    Progressive macular hypomelanosis in Singapore: a clinico-pathological study

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 6 2006
    Sujith Prasad W. Kumarasinghe MBBS
    Introduction, Progressive macular hypomelanosis (PMH), a condition of uncertain etiology, is characterized by asymptomatic hypopigmented macules predominantly located on the trunk. To date, there are no reports from South-East Asia concerning this condition. We sought to record the clinical features of PMH in Asian patients, identify etiologic factors, and study the structural and ultrastructural features of melanocytes in this disorder. Methods, Patients who presented to the National Skin Center with acquired, hypopigmented macules on the trunk, without a history of inflammation or infection, were recruited. Erythrocyte sedimentation rate (ESR), complete blood count, fasting blood glucose, liver function tests, skin scrapings for fungi, and skin biopsy specimens (from lesional and normal skin) were obtained. Biopsies were stained with hematoxylin and eosin (H&E), Fontana Masson, an immunohistochemical panel for identification of melanocyte differentiation antibodies (HMB 45, Melan A, and S100) and CD 68. Electron microscopy (EM) was also performed. The patients were evaluated every 3 months. Results, During a 9 month period, eight patients (all Chinese) presented with hypopigmented, ill-defined, confluent macules involving the lower aspect of the trunk. There were four men and four women, and the mean age was 25.9 years (range 19,45 years). Skin scrapings were negative for fungi and laboratory tests were normal. Microscopic evaluation of skin biopsy speciments showed reduced pigmentation of lesional as compared with normal appearing skin, but H&E-stained sections revealed only minimal histologic differences between lesional and normal skin. EM demonstrated a statistically significant (P = 0.047, Wilcoxon Signed Rank Test, Wilcoxon 95% CI 0.02,0.62) higher ratio of stage IV and late stage III (dark) melanosomes in normal vs. lesional skin. Conclusions, PMH may occur among young adults in Singapore. Its etiology is uncertain. The melanin content of lesional skin appears to be less than that in normal sites. EM shows a higher ratio of immature melanosomes in lesional vs. normal skin. [source]


    Iron and vitamin deficiencies, endocrine and immune status in patients with primary Sjögren's syndrome

    ORAL DISEASES, Issue 3 2001
    IMC Lundström
    OBJECTIVES: To study the prevalence of iron and vitamin deficiencies, endocrine disorders and immunological parameters in patients with primary Sjögren's syndrome (1°SS). DESIGN AND SUBJECTS: At the time of the establishment of the diagnosis of 1°SS in 43 consecutive patients, a clinical examination including haematological analyses was performed. The patients' medical records were also reviewed. SETTING: Patients referred for diagnosis to The University Hospital, Linköping, a secondary or tertiary referral hospital serving the middle part of southern Sweden. RESULTS: In total, current or previously treated iron and vitamin deficiencies were registered for 63% of the 1°SS patients (iron 51%, vitamin B12 25%, folate 9%). Current low ferritin was noted in 24%, low iron saturation in 37%, decreased vitamin B12 in 13% and folate in 9%. Thyroid disease was found in a total of 33% and 30% had had autoimmune thyroiditis. Three patients (7%) had verified diabetes mellitus. Erythrocyte sedimentation rate (ESR) was raised in 65% of the patients and 84% had a polyclonal increase of Ig. Rheumatoid factor (RF) was detected in 85%, antinuclear antibody (ANA) in 74%, anti-SS-A in 88% and anti-SS-B in 73% of the patients. CONCLUSION: Iron and vitamin deficiencies and thyroid diseases are common in patients with 1°SS. Since these disorders often are treatable and may affect the patients' distress as well as their immune and exocrine function, an active, recurrent search for deficiencies, endocrine diseases and other frequently recorded disorders is recommended.

    Objective To determine the construct and criterion validity of the British Isles Lupus Assessment Group 2004 (BILAG-2004) index for assessing disease activity in systemic lupus erythematosus (SLE). Methods Patients with SLE were recruited into a multicenter cross-sectional study. Data on SLE disease activity (scores on the BILAG-2004 index, Classic BILAG index, and Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K]), investigations, and therapy were collected. Overall BILAG-2004 and overall Classic BILAG scores were determined by the highest score achieved in any of the individual systems in the respective index. Erythrocyte sedimentation rates (ESRs), C3 levels, C4 levels, anti,double-stranded DNA (anti-dsDNA) levels, and SLEDAI-2K scores were used in the analysis of construct validity, and increase in therapy was used as the criterion for active disease in the analysis of criterion validity. Statistical analyses were performed using ordinal logistic regression for construct validity and logistic regression for criterion validity. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Results Of the 369 patients with SLE, 92.7% were women, 59.9% were white, 18.4% were Afro-Caribbean and 18.4% were South Asian. Their mean ± SD age was 41.6 ± 13.2 years and mean disease duration was 8.8 ± 7.7 years. More than 1 assessment was obtained on 88.6% of the patients, and a total of 1,510 assessments were obtained. Increasing overall scores on the BILAG-2004 index were associated with increasing ESRs, decreasing C3 levels, decreasing C4 levels, elevated anti-dsDNA levels, and increasing SLEDAI-2K scores (all P < 0.01). Increase in therapy was observed more frequently in patients with overall BILAG-2004 scores reflecting higher disease activity. Scores indicating active disease (overall BILAG-2004 scores of A and B) were significantly associated with increase in therapy (odds ratio [OR] 19.3, P < 0.01). The BILAG-2004 and Classic BILAG indices had comparable sensitivity, specificity, PPV, and NPV. Conclusion These findings show that the BILAG-2004 index has construct and criterion validity.

    Association of components of the metabolic syndrome with the appearance of aggregated red blood cells in the peripheral blood.

    DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 2 2005
    An unfavorable hemorheological finding
    Abstract Background Components of the metabolic syndrome are associated with low-grade inflammation. This can be accompanied by the synthesis of sticky proteins and erythrocyte aggregation. Methods The degree of erythrocyte aggregation was evaluated by a simple slide test and image analysis along with other markers of the acute-phase response, including the white blood cell count (WBCC), erythrocyte sedimentation rate (ESR), fibrinogen and high sensitivity C-reactive protein (hs-CRP) concentrations. Patients were categorized in four groups according to the absence or presence of 1, 2 and 3 or more components of the metabolic syndrome. Results We examined a total of 1447 individuals (576 women and 871 men) who gave their informed consent for participation. A significant cardiovascular risk factors, age and hemoglobin adjusted correlation was noted between the degree of erythrocyte aggregation and the number of components of the metabolic syndrome (r = 0.17, p < 0.0005). This correlation was better than that observed for clottable fibrinogen (r = 0.13 p < 0.0005), for ESR (r = 0.11 p < 0.0005) or WBCC (r = 0.13 p < 0.0005). A somewhat better correlation was noted for hs-CRP (r = 0.26 p < 0.0005). Conclusions The multiplicity of components of the metabolic syndrome is associated with enhanced erythrocyte aggregation, probably related to the presence of multiple adhesive macromolecules in the peripheral blood. The enhanced aggregation might contribute to capillary slow flow, tissue deoxygenation as well as vasomotor tone changes in the presence of multiple components of this syndrome.

    Rheological determinants of red blood cell aggregation in diabetic patients in relation to their metabolic control

    DIABETIC MEDICINE, Issue 2 2002
    K. Elishkevitz
    Abstract Aims To determine whether increased red blood cell adhesiveness/aggregation in diabetic patients is related to the extent of their metabolic control. Methods We measured erythrocyte adhesiveness/aggregation in a group of 85 adult patients with diabetes mellitus by using citrated venous whole blood and a simple slide test. The erythrocyte adhesiveness/aggregation was determined by measuring the size of the spaces that are formed between the aggregated erythrocytes. We divided the patients into those with either low or high erythrocyte adhesiveness/aggregation values. Results The erythrocyte adhesiveness/aggregation values of the two groups differed significantly in terms of their fibrinogen concentration, erythrocyte sedimentation rate, high sensitive C-reactive protein (CRP), total cholesterol and triglyceride concentrations. There was no difference between the two groups regarding the concentrations of HbA1c. Logistic regression was applied to construct a model to predict the belonging of a patient in the low or high erythrocyte adhesiveness/aggregation group. A linear regression was applied to construct a model to predict the erythrocyte adhesiveness/aggregation values. Both models turned out to include gender, age, fibrinogen, triglyceride, retinopathy, coronary artery disease and age and gender interaction. Neither HbA1c nor CRP entered the models. Conclusions The degree of erythrocyte adhesiveness/aggregation and several variables of the acute-phase response in patients with diabetes mellitus are not directly related to the degree of metabolic control as evaluated by means of HbA1c concentration. Diabetic patients might benefit from rheological or anti-inflammatory interventions regardless of their metabolic control. [source]


    Investigations on the Structural Damage in Human Erythrocytes Exposed to Silver, Gold, and Platinum Nanoparticles

    ADVANCED FUNCTIONAL MATERIALS, Issue 8 2010
    P. V. Asharani
    Abstract Human erythrocytes or red blood cells (RBCs), which constitute 99% of blood cells, perform an important function of oxygen transport and can be exposed to nanoparticles (NPs) entering into the human body during therapeutical applications involving such NPs. Hence, the haemocompatibility of the Ag, Au, and Pt NPs on human RBCs is investigated. The parameters monitored include haemolysis, haemagglutination, erythrocyte sedimentation rate, membrane topography, and lipid peroxidation. The findings suggest that platinum and gold NPs are haemocompatible compared to Ag NPs. Erythrocytes exhibit significant lysis, haemagglutination, membrane damage, detrimental morphological variation, and cytoskeletal distortions following exposure to Ag NPs at a concentration of 100,µg,mL,1. Exposure of Ag+ to RBCs shows no lysis or deterioration, implying that the observed toxicity is solely due to NPs. The haemolyzed erythrocyte fraction has the ability to induce DNA damage in nucleated cells. Additionally, multiple pits and depressions are observed on RBC membrane following exposure to Ag NPs (50,µg,mL,1 onwards). Hence, it is apparent that Ag NPs exhibit toxicity on RBCs and on other cells that are exposed to NP-mediated haemolyzed fractions. [source]


    Effect of tick parasitism on the health status of a passerine bird

    FUNCTIONAL ECOLOGY, Issue 6 2008
    D. J. A. Heylen
    Summary 1Little information is available on the ecological interactions between ticks and their hosts under natural conditions, and particularly so for avian hosts. To understand this host,parasite interaction it is necessary to assess the physiological harm ticks can do to their host. 2We combined observational and experimental (field and laboratory) data to examine the effects of a common tick species with major economic importance, the sheep tick (Ixodes ricinus), on the health status of a common passerine bird, the great tit (Parus major). 3In the laboratory experiment a parallel group design was carried out in which the birds of the experimental group were infested with 3,10 nymphs, whereas the birds of the control group were kept free of ticks and received a sham treatment. Both groups were stratified according to age and sex. Health parameters were measured the day before and 3 days after infestation or sham treatment: haematocrit level, erythrocyte sedimentation rate, leucocyte concentration and general body condition (body mass corrected for body size). 4No effects of age were observed on any of the health parameters. The decrease in haematocrit level in the experimental group was significantly greater than in the control group. Moreover, infested males suffered more blood depletion than infested females. The increase in sedimentation rate was greater in the experimental group than in the control group. Surprisingly, no treatment effects were found on leucocyte concentrations, which may indicate immunoregulation by the ticks on components of the birds' cellular immune response. Also no difference in general body condition between the treatment groups was found. None of the infested birds died during infestation. 5Lower haematocrit levels in infested birds, but unaffected leucocyte concentrations and general body condition are confirmed by field data (experimental and observational) of adult birds during breeding season. 6Neither haematocrit level nor general body condition was associated with parasite intensity among infested birds, suggesting that immature Ixodes ricinus are not resource limited at high natural densities. Still, the measurable direct harm caused by sheep tick infestations calls for further study on its importance for the evolutionary ecology of passerine hosts. [source]


    Effects of food abundance and predictability on body condition and health parameters: experimental tests with the Hooded Crow

    IBIS, Issue 4 2002
    Camilla Acquarone
    It has been shown that small passerines can counteract variability of food resources by actively regulating their body reserves through an increase of mass. However, the effects of food predictability on body mass regulation and other body parameters, such as immune functions, in larger species have been little studied. To analyse the response of the Hooded Crow Corvus corone to food abundance and predictability, we performed three experiments with controlled food provisioning under laboratory conditions. Body mass, TOBEC (total body electrical conductivity) lean mass index, blood parameters and immune organ masses were measured at the beginning and end of a 15-day period. In the first experiment, the food release was predictable (same amount each day) but the quantity of food delivered to five groups of birds varied (37, 75, 100, 150 or 300 g/day). Low food levels induced a greater decrease in mass accompanied by an increase in erythrocyte sedimentation rate. In the second experiment, the same average quantity of food (100 g) was supplied according to either predictable or unpredictable (random) schedules. In this case, the crows lost more mass, and their erythrocyte sedimentation rate increased when food was unpredictable. In the third experiment, the same average quantity of food (150 g) was supplied according to either a predictable schedule or two schedules with different levels of variability. The group with a low level of variability did not differ from the control, while the group with a highly variable feeding schedule lost more mass. In this group, the higher mass loss was associated with greater variation of the erythrocyte sedimentation rate and a reduced Phytohaemagglutinin index of immunocompetence and haematocrit value. The results of experiments 2 and 3 contrast with findings in other passerines, which increase their mass when food availability is unpredictable. It appears that a body mass decrease in the Hooded Crow can be induced by a reduction of either food abundance (exp. 1) or food predictability (exp. 2, 3), and it is accompanied by a worsening of health state.

    Probiotic preparation VSL#3 induces remission in children with mild to moderate acute ulcerative colitis: A pilot study

    INFLAMMATORY BOWEL DISEASES, Issue 5 2009
    Hien Q. Huynh MD
    Abstract Background: Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) that has periods of exacerbated symptoms and periods that are symptom-free. The treatment of active UC with probiotic bacteria could possibly induce remission. We evaluated the clinical efficacy and safety profile of probiotic preparation VSL#3 in the treatment of mild to moderate acute UC in the pediatric population. Methods: Eighteen eligible patients between the ages of 3,17 with mild to moderate acute UC received open-label VSL#3 daily in 2 divided doses for 8 weeks. The disease activity pre- and post-VSL#3 therapy was assessed by the simple clinical colitis activity index (SCCAI); Mayo ulcerative colitis endoscopic score; inflammatory markers: erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP); serum cytokine profiling; and rectal tissue microbial profiling done at baseline and at week 8. Results: Thirteen patients completed 8 weeks of VSL#3 treatment and 5 patients were withdrawn due to lack of improvement. Remission (defined as SCCAI ,3) was achieved in 56% of children (n = 10); response (decrease in SCCAI ,2, but final score ,5) in 6% (n = 1); and no change or worsening in 39% (n = 7). Post-VSL#3 treatments demonstrated a bacterial taxonomy change in rectal biopsy. The VSL#3 was well tolerated in clinical trials and no biochemical and clinical adverse effects attributed to VSL#3 were identified. Conclusions: Treatment of pediatric patients diagnosed with mild to moderate UC with VSL#3 resulted in a remission rate of 56% and a combined remission/response rate of 61%.

    Efficacy of infliximab in pediatric Crohn's disease: A randomized multicenter open-label trial comparing scheduled to on demand maintenance therapy

    INFLAMMATORY BOWEL DISEASES, Issue 3 2009
    Frank M. Ruemmele MD
    Abstract Background: Infliximab (IFX) is efficacious in inducing remission in severe forms of pediatric Crohn's disease (CD). Adult studies indicate that IFX is also safe and well tolerated as maintenance therapy. The present study aimed to evaluate in a prospective manner the efficacy and safety of IFX as maintenance therapy of severe pediatric CD comparing scheduled and "on demand" treatment strategies. Methods: Forty children with CD (nonpenetrating, nonstricturing as well as penetrating forms, mean age: 13.9 ± 2.2 years) with a severe flare-up (Harvey,Bradshaw Index [HBI] ,5, erythrocyte sedimentation rate [ESR] >20 mm/h) despite well-conducted immunomodulator therapy (n = 36 azathioprine, n = 1 mercaptopurine, n = 3 methotrexate) combined with steroids were included in this randomized, multicenter, open-label study. Three IFX infusions (5 mg/kg) were administered at week (W)0/W2/W6. At W10, clinical remission (HBI <5) and steroid withdrawal were analyzed and IFX responders were randomized to maintenance therapy over 1 year: group A, scheduled every 2 months; group B, "on demand" on relapse. Results: In all, 34/40 children came into remission during IFX induction therapy (HBI: 6.7 ± 2.5 (WO) vs. 1.1 ± 1.5 (W10); P < 0.001). At the end of phase 2, 15/18 (83%) patients were in remission in group A compared to 8/13 (61%) children in group B (P < 0.01), with a mean HBI of 0.5 versus 3.2 points (group A versus B, P = 0.011). In group A, 3/13 (23.1%) children experienced a relapse compared to 11/12 (92%) children in group B. No severe adverse event occurred during this trial. Conclusions: IFX is well tolerated and safe as maintenance therapy for pediatric CD, with a clear advantage when used on a scheduled 2-month basis compared to an "on demand" basis.

    Impaired intestinal iron absorption in Crohn's disease correlates with disease activity and markers of inflammation

    INFLAMMATORY BOWEL DISEASES, Issue 12 2006
    Gaith Semrin MD
    Abstract Background: Anemia in patients with Crohn's disease (CD) is a common problem of multifactorial origin, including blood loss, malabsorption of iron, and anemia of inflammation. Anemia of inflammation is caused by the effects of inflammatory cytokines [predominantly interleukin-6 (IL-6)] on iron transport in enterocytes and macrophages. We sought to elucidate alterations in iron absorption in pediatric patients with active and inactive CD. Methods: Nineteen subjects with CD (8 female, 11 male patients) were recruited between April 2003 and June 2004. After an overnight fast, serum iron and hemoglobin levels, serum markers of inflammation [IL-6, C-reactive protein (CRP), and erythrocyte sedimentation rate], and a urine sample for hepcidin assay were obtained at 8 am. Ferrous sulfate (1 mg/kg) was administered orally, followed by determination of serum iron concentrations hourly for 4 hours after the ingestion of iron. An area under the curve for iron absorption was calculated for each patient data set. Results: There was a strong inverse correlation between the area under the curve and IL-6 (P = 0.002) and area under the curve and CRP levels (P = 0.04). Similarly, the difference between baseline and 2-hour serum iron level (,[Fe]2hr) correlated with IL-6 (P = 0.008) and CRP (P = 0.045). When cutoff values for IL-6 (>5 pg/mL) and CRP (>1.0 mg/dL) were used, urine hepcidin levels also positively correlated with IL-6 and CRP levels (P = 0.003 and 0.007, respectively). Conclusions: Subjects with active CD have impaired oral iron absorption and elevated IL-6 levels compared with subjects with inactive disease. These findings suggest that oral iron may be of limited benefit to these patients. Future study is needed to define the molecular basis for impaired iron absorption. [source]


    Efficacy and tolerance of infliximab in children and adolescents with Crohn's disease

    INFLAMMATORY BOWEL DISEASES, Issue 6 2004
    Dr. Thierry Lamireau
    Abstract Infliximab, a monoclonal antibody against tumor necrosis factor-alpha, has been shown to be effective for the treatment of refractory Crohn's disease in adult patients, but experience in pediatrics is limited. This retrospective study included 88 children and adolescents, 39 girls and 49 boys, with a median age of 14 years (range 3.3,17.9). Infliximab was indicated for active disease (66%) and/or fistulas (42%) that were refractory to corticosteroids (70%), and/or other immunosuppressive (82%) agents, and/or parenteral nutrition (20%). Patients received 1 to 17 infusions (median 4) of 5 mg/kg (range 3.8,7.3) of infliximab during a median time period of 4 months (1,17 months). Infusion reaction was noted in 13 patients (15%), with a total of 16 reactions in 450 infusions (4%). At Day 90 after the first infusion of infliximab, symptoms improved in 49% of patients, whereas 29% of patients were in remission and 13% of patients relapsed. From Day 0 to Day 90, Harvey,Bradshaw score decreased from 7.5 to 2.8 (P < 0.001), C-reactive protein from 36 to 16 mg/L (P < 0.01), and 1-hour erythrocyte sedimentation rate from 35 to 17 mm (P < 0.01). Dosage of corticosteroids decreased from to 0.59 to 0.17 mg/kg/d (P < 0.001); 53% of patients could be weaned of corticosteroids and 92% of parenteral nutrition. Treatment with infliximab is well tolerated and effective in most children and adolescents with Crohn's disease that is refractory to conventional immunosuppressive therapy. Nevertheless, long-term efficacy remains to be shown, and further studies are urgently needed to precisely determine the best modality of continuing treatment. [source]


    A case of progressive pseudorheumatoid arthropathy of ,childhood' with the diagnosis delayed to the fifth decade

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 10 2006
    A. CEFLE
    Summary Progressive pseudorheumatoid arthropathy of childhood (PPAC) is a rare single gene disorder which is frequently misdiagnosed as juvenile rheumatoid arthritis. It is characterised with arthralgia, joint contractures, bony swelling of metacarpophalangeal and interphalangeal joints and platyspondyly. Clinical and laboratory signs of joint inflammation such as synovitis, a high erythrocyte sedimentation rate and an elevated C-reactive protein level are usually absent. Although the disease begins early in life (usually between 3 and 8 years of age), the diagnosis may be delayed. In the present case report, we describe a male patient diagnosed with PPAC at the age of 46 years, although he had been exhibiting the typical radiological and clinical features of the disease since the age of 7 years.

    Giardia lamblia intestinalis: a new pathogen with possible link to Kikuchi,Fujimoto disease.

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 12 2004
    An additional element in the disease jigsaw
    Summary A 16-year-old Caucasian girl of Albanian origin was admitted to the hospital complaining of intermittent fever (38 °C) for a week, nausea, vomiting, and abnormal laboratory findings (elevated serum aminotransferases levels AST/ALT 77/40 U/l and erythrocyte sedimentation rate 80 mm/first hour, as well as leukopenia 2.5 × 103/mm3), which were found in a blood examination. Physical examination revealed slight hepatomegaly and splenomegaly, as well as cervical and axillary lymphadenopathy. A diagnostic open lymph node biopsy was performed and Kikuchi,Fujimoto disease (KFD) was established based on the characteristic histological pattern. Other abnormal laboratory findings were C-reactive protein 6.8 mg/dl and serum lactate dehydrogenase 900 U/l. Her history included a diarrhoea syndrome 2 months before the present admission, during the summer holidays, for which she was treated with metronidazole. At that time, characteristic cysts of giardia lamblia intestinalis were observed in the stools. Herein, we present this case hypothesising that the protozoal infection caused by the giardia lamblia intestinalis was probably triggering an immune response leading to KFD. The patient's age in combination with this firstly reported protozoal pathogen, as a triggering agent leading to KFD, consist a very interesting originality. Additionally, some review data is also given. [source]


    Steroid responsiveness in a case of Riedel's thyroiditis and retroperitoneal fibrosis

    INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2004
    P.K. Moulik
    Summary Riedel's thyroiditis is a rare chronic inflammatory disease of the thyroid characterised by an invasive fibrotic process. We present a lady with newly diagnosed hypothyroidism, rapidly enlarging hard, fixed goitre, strongly positive thyroid antibodies and raised erythrocyte sedimentation rate (ESR). A tru-cut biopsy confirmed Riedel's struma. Regression of the goitre and reduction of antibody titres occurred after starting prednisolone, which was stopped after 10 months. Six months later, she presented with renal failure due to retroperitoneal fibrosis that was successfully treated by reinstitution of steroids and ureteric stenting. Very high titres of thyroid antibodies and hypothyroidism predating development of goitre suggest coexistence of Hashimoto's thyroiditis and Riedel's thyroiditis. Tru-cut biopsy obviated the need for open thyroidectomy. A predominantly inflammatory as opposed to fibrotic thyroid histology may predict good response to steroids. Relapse following steroid withdrawal may not only be in the thyroid but also at other sites. [source]


    Tuberculosis verrucosa cutis: antitubercular therapy, a well-conceived diagnostic criterion

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 3 2005
    Virendra N. Sehgal MD
    A 39-year-old housewife sustained inadvertent trauma to the right index finger about 6 years ago, whilst stitching clothes. A couple of weeks later, the site of trauma became hard and gritty. Ever since, it has progressed slowly, without any appreciable outward sign. It was not associated with any discomfort/pain. Consequent on an opinion from a surgeon, it was decided to operate on the right index finger. During the operation, under local anesthesia, a hard and gritty material was removed. The material was subjected to histopathologic study. Several stitches were applied to the wound. It failed to respond to antimicrobial therapy over a 4-week period, prompting the patient to seek another opinion. Examination of the skin surface revealed a plaque with an irregular configuration on and around the distal interphalangeal joint of the right index finger. It was erythematous and pigmented. The top of the plaque was irregular and had alternating elevations and depressions (Fig. 1). Diascopy was negative for apple jelly nodule. A bacillus Calmette,Guérin (BCG) vaccination scar was identified on the left deltoid. There was no regional lymphadenopathy or systemic abnormality. Mantoux test with intradermal injection of 0.1 mL SPAN's tuberculin (purified protein derivative/5 tuberculin units/0.1 mL) (Span Diagnostic Ltd., Murat, India) was negative after 72 h. Investigations, including total and differential leukocyte count, erythrocyte sedimentation rate, serum biochemistry, and renal and liver function tests, were within the normal range, as was a chest X-ray. Figure 1. Tuberculosis verrucosa cutis before (a) and after (b) antitubercular therapy (ATT) Hematoxylin and eosin-stained sections prepared from the biopsy taken from the lesion revealed noteworthy changes in the epidermis and the dermis. The former was marked by the presence of hyperkeratosis, acanthosis, and papillomatosis, whilst the latter contained tubercle granulomas. Each of the granulomas was well formed and consisted of large numbers of lymphocytes, histiocytes, and foreign body (Langerhans') giant cells (Fig. 2). Caseation necrosis and acid-fast bacilli could not be demonstrated. The preceding revelations were fairly conducive to the diagnosis. Accordingly, antitubercular therapy (ATT), comprising 450 mg of rifampicin, 300 mg of isonicotinic acid hydrazide, and 800 mg of ethambutol, was recommended for oral administration each day for 60 days. The outcome of the treatment was satisfactory, resulting in perceptible regression of the skin lesion (Fig. 1b). The patient was advised to continue the treatment for another 30 days, after which 450 mg of rifampicin and 300 mg of isonicotinic acid hydrazide were to be continued for another 6 months. Figure 2. Tuberculosis verrucosa cutis depicting well-formed tubercle(s) comprising lymphocytes, histiocytes, neutrophils, and a few giant cells (hematoxylin and eosin, × 100) [source]


    Cutaneous sarcoid-like granulomas with alveolar hemorrhage and c-ANCA PR-3

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 9 2004
    Natividade Rocha MD
    A 28-year-old woman, employed as a leather factory worker, noted asymptomatic, well-delimited plaques on both knees, 6 years ago. The plaques were violaceous with a smooth surface. One appeared over a post-traumatic scar from childhood (Fig. 1). Two years later, she began to complain of symptoms suggestive of polyarthritis, first of the small joints of the hands (proximal interphalanges) and then of the larger joints (wrists, elbows, and knees). She was diagnosed with rheumatoid arthritis and began treatment with nonsteroidal anti-inflammatory drugs for 1 month without any change. Deflazacort, 12 mg/day, and hydroxychloroquine, 400 mg/day, were administered for 3 months, with improvement of her articular complaints, but not her skin lesions. Figure 1. Well-delimited, violaceous plaques with a smooth surface on the knees, one over an old post-traumatic scar One year later, she complained of dysphonia, which remitted spontaneously after some weeks. After one additional year, she noted papules, with similar characteristics to the plaques, on the elbows, and two well-delimited orange-to-brown plaques on the forehead (Fig. 2). Figure 2. Orange,brown plaques symmetrically placed on the forehead During the fifth year of the disease, she was referred for the first time to a dermatologist, who biopsied one of the knee lesions. The histologic result was compatible with "sarcoid granuloma." At that time, she presented with skin lesions as her only complaint. Sarcoidosis was suspected based on a chest X-ray, which revealed hilar lymphadenopathy and diffuse accentuation of the interstitium. In November 2000, she suddenly developed fever (40 °C), cough with hemoptysis, dysphonia, and subcutaneous nodules on the palmar surface of the fingers of both hands that were painless, well-delimited, 5 mm in diameter, and firm (Fig. 3). She reported a weight loss of 12 kg in the previous 3 months. Pulmonary condensation was found on auscultation, and she had palpable hepatomegaly. Peripheral lymphadenopathy was not present. Figure 3. Painless, well-delimited, firm subcutaneous nodules on the palmar surface of the fingers Laboratory investigations revealed normochromic, normocytic anemia (hemoglobin, 7.7 g/dL), iron deficit, a white blood cell count of 16,000/µL with neutrophilia, an erythrocyte sedimentation rate of 130 mm/h, elevation of liver enzymes, a slight increase in angiotensin-converting enzyme (ACE) level (72 U/L), hypergammaglobulinemia (IgG, 3350 mg/dL), antinuclear antibody (ANA) of 1 : 320, and a slight increase in CD4 and decrease in CD8 lymphocytes with normal cellular morphology in blood. Renal function, urine sediment, urine and serum calcium, complement (C4), dsDNA, antimitochondrial antibody, direct and indirect Coombs test, antineutrophil cytoplasmic antibody (ANCA), tuberculin skin tests, viral markers of hepatitis B, C, and human immunodeficiency virus (HIV), electrocardiogram (ECG), ophthalmic examinations, and culture for infectious agents in blood and sputum were all normal or negative. Computed tomography (CT) scan showed an infiltrate in the upper right pulmonary lobule with a central cavity and bilateral hilar lymphadenopathy (Fig. 4). Homogeneous hepatosplenomegaly was present. The bronchoalveolar lavage (BAL) showed a slight lymphocytic increase predominantly of CD8 cells and hemosiderosis. Stains for infectious agents, including acid-fast bacillus, fungi, Mycoplasma, and Legionella, were negative. Three biopsies from the forehead, elbows, and knees showed well-formed noncaseating epithelioid cell granulomas with giant cells of the Langhans type in the dermis, suggestive of sarcoidosis (Figs 5 and 6). A fourth biopsy from a finger nodule demonstrated inflammatory infiltration of the dermis and necrosis with cellular debris. Vasculitis was not seen (Fig. 7). Figure 4.

Nevertheless, on the first evaluation after hospitalization, the CT scan showed persistence of the pulmonary cavity (Fig. 8). A repeat ANCA determination was positive (cytoplasmic pattern, c-ANCA) at 1 : 640 by indirect immunofluorescence (IIF). Antiproteinase-3 antibody was demonstrated at 78 by enzyme-linked immunosorbent assay (ELISA). Figure 8. Computed tomography scan showing persistence of the pulmonary cavity She underwent an open lung biopsy which revealed intra-alveolar hemorrhage and scanty noncaseating epithelioid cell granulomas of the sarcoidosis type in the peripheral blood vessels without vasculitis. A diagnosis of Wegener's granulomatosis was made and she began prednisolone (1 mg/kg/day) and oral cyclophosphamide (2 mg/kg/day). One year later, she is asymptomatic, the skin lesions have completely remitted, c-ANCA is negative, and the CT scan shows partial regression of the pulmonary cavity. [source]


    A case of necrobiotic xanthogranuloma without paraproteinemia presenting as a solitary tumor on the thigh

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 6 2003
    Sung Eun Chang MD
    A 82-year-old Korean woman had had a 6-month history of an asymptomatic, flat, hard, red to brown tumor on her right thigh. This lesion had been slowly enlarging with an advancing margin. She had noted gradually developing pain associated with necrosis and ulceration on the lesion. Examination revealed a solitary, 8 × 7.5 cm, yellow to dark red, telangiectatic tumor with multiple areas of punched out ulceration and a peripheral elevated yellowish margin on the right inner upper thigh (Fig. 1). No clinically similar lesions on the periorbital area or other sites were seen. Histologic examination revealed a massive palisading granulomatous infiltration with several layers of extensive bands of necrobiotic zone in the entire dermis and deep subcutaneous tissue (Fig. 2a). In the granulomatous infiltrate in the dermis and subcutis, many various-shaped, some bizarre, angulated, foreign-body type multinucleated giant cells, many Touton giant cells, and a few Langhans giant cells were found to be scattered (Fig. 2b). There were numerous xanthomatized histiocytes. Dense infiltration of lymphoplasma cells was seen in the periphery of the granuloma and perivascularly. Conspicuous granulomatous panniculitis composed of lymphoplasma cells, polymorphonuclear cells, foam cells, and Touton and foreign-body giant cells was also seen. However, cholesterol clefts and lymphoid follicles were not seen. Subcutaneous septae were widened by necrobiotic change and fibrosis with thrombosed large vessels. Gram, Gomeri-methenamine silver and acid-fast stains were negative. The necrobiotic areas were positive to alcian blue. Laboratory investigation revealed elevated white blood cell counts, anemia and elevated erythrocyte sedimentation rate. The following parameters were within the normal range: lipids, glucose, renal and liver function tests, serum complements, serum immunoglobulins, cryoglobulins and antinuclear antibodies. The findings of chest X-ray, skull X-ray and ectorcardiography were normal. Serum electrophoresis and serum immunoelectrophoresis revealed no abnormality. The patient was diagnosed as having necrobiotic xanthogranuloma without paraproteinemia. She was treated with oral steroid (0.5,0.6 mg/kg) and NSAIDS for 1 month with partial improvement of pain and the lesion ceased to enlarge. In the following 1 year of follow-up, with only intermittent NSAIDS, her lesion did not progress and there were no signs of systemic involvement or new skin lesions. Figure Figure 1 .

    An unusual association of pemphigus vulgaris with hyperprolactinemia

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2002
    MNAMS, Sujay Khandpur MD
    A 21-year-old unmarried woman presented with oral ulcerations and generalized, itchy, fluid-filled, skin lesions of 10 days' duration. The lesions ruptured spontaneously, resulting in extensive denuded areas covered by crusts. One month prior to this, she experienced pain and enlargement of both breasts with galactorrhea. Her menstrual cycles were normal initially, but later she developed menstrual irregularities. No past history suggestive of any other systemic or skin disease, including atopy or drug allergies, could be obtained. Her family history was not contributory. Dermatologic examination revealed multiple, flaccid bullae and extensive denuded areas of skin covered with crusts over the scalp, face, trunk, and upper and lower limbs (Fig. 1). Bulla spread sign and Nikolsky's sign were positive. The oral mucosa, including the lips, buccal surface, tongue, and palate, showed multiple erosions covered with necrotic slough. The rest of the mucocutaneous and systemic examination was within normal limits. Figure 1. Extensive erosions and flaccid bullae over the trunk with breast enlargement The patient's diagnostic work-up revealed: hemoglobin, 11.2 g%; total leukocyte count, 7400/mm3; differential leukocyte count, P62L34E2M2; erythrocyte sedimentation rate, 34 mm/h. A peripheral blood smear examination, urinalysis, blood sugar, and renal and liver function tests were normal. Venereal Disease Research Laboratory (VDRL) test and enzyme-linked immunoabsorbent assay (ELISA) for human immunodeficiency virus (HIV) were nonreactive. Antinuclear antibody, lupus erythematosus (LE) cell, rheumatoid factor, and anti-dsDNA levels were normal. Serum protein electrophoresis demonstrated increased levels of immunoglobulin G (IgG) antibody. The serum prolactin level was significantly raised to 139.49 ng/mL (normal, 3.6,18.9 ng/mL). The sex hormone levels, however, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and progesterone, were within normal limits. The thyroid hormone profile was also unaltered. Chest X-ray was normal. Ultrasound of the abdomen and pelvis revealed no visceral abnormality and computerized tomography (CT) scan of the pituitary sella showed no adenoma. Mammography was negative for breast malignancy. A Tzanck smear prepared from the base of the erosion showed multiple acantholytic cells and lymphocytes. Histologic examination from an intact vesicle was suggestive of pemphigus vulgaris (PV), showing a suprabasal cleft with acantholytic cells and the basal layer demonstrating a "row of tombstones" appearance (Fig. 2). Direct immunofluorescence (DIF) revealed the intercellular deposition of IgG and C3 throughout the epidermis in a "fishnet pattern." Indirect immunofluorescence (IIF) test performed on rat esophagus for circulating IgG antibody was positive in a titer of 1 : 120. Figure 2. Photomicrograph showing suprabasal cleft with "row of tombstones" appearance, suggestive of pemphigus vulgaris (hematoxylin and eosin, × 40) Based on the clinical and immunohistological features, a diagnosis of PV with idiopathic hyperprolactinemia was made. The patient was treated with bromocriptine mesylate (Tablet Proctinal, Glaxo Wellcome Ltd, India) at a dose of 2.5 mg twice a day. After 2 months of therapy, significant improvement in the skin lesions was observed. The existing lesions re-epithelialized with a drastic reduction in the number and distribution of new vesicles. However, no change in the mucosal erosions was noticed. IIF test demonstrated a lower antibody titer (1 : 40). The breast complaints also improved with a reduction in serum prolactin level to 6.5 ng/mL. The patient refused further treatment as she experienced nausea and dizziness with bromocriptine. After 2 weeks, the disease relapsed with the appearance of new vesicles over the forearms, abdomen, back, and thighs. She again complained of breast tenderness and galactorrhea, and the serum prolactin level was 95 ng/mL. The IgG titer increased to 1 : 120. Hence, treatment with oral prednisolone (2 mg/kg/day) and bromocriptine (2.5 mg twice a day) with an antiemetic was initiated. After 6 weeks, the skin lesions had cleared completely, the breast symptoms had improved, menses had become regular, and the prolactin level had decreased to 4 ng/mL. IIF test was negative for circulating antibody. Steroids were tapered off and maintenance therapy with bromocriptine at a dose of 2.5 mg/day was continued. [source]


    Lichenoid photodermatitis associated with nimesulide

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2001
    Umit Tursen MD
    An 81-year-old-female patient presented with a 2 week history of erythematous to violaceous lichenoid papules and plaques exhibiting a reticulated pattern on the ,,V'' area of the chest and dorsal hands. Fine, whitish reticulated networks were present over the surface of many well developed papules. The lesions were sharply demarcated and moderately pruritic (Fig. 1). Figure 1. ,Violaceous lichenoid papules with reticular pattern located on the ,,V'' area of the chest The result of routine complete blood cell count, urinalysis, erythrocyte sedimentation rate, liver and kidney function tests were within normal limits. Antinuclear and anti-DNA antibodies were negative, and total C3 and C4 complement levels were normal. Hepatitis B surface antigen, anti-Hepatitis B surface antigen, anti-Hepatitis B core IgM antibody were negative, while anti-Hepatitis C virus antibody was positive. A skin biopsy specimen obtained from the neck of our patient revealed an interface lichenoid dermatitis accompanied by individual necrotic epidermal keratinocytes, parakeratosis and eosinophils in the infiltrate (Fig. 2). Figure 2. ,Interface lichenoid dermatitis accompanied by individual necrotic epidermal keratinocytes and parakeratosis (Hematoxylin and eosin; original magnification, × 200) Nimesulide therapy was stopped and the patient was treated with topical corticosteroids and systemic antihistamines. The eruption resolved within 5 days. The rash returned following nimesulide rechallenge. [source]


    Juvenile psoriatic arthritis with nail psoriasis in the absence of cutaneous lesions

    INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 1 2000
    Carola Duran-McKinster MD
    A 4-year-old white boy without a significant family history had morning stiffness and painful swelling of his left knee and ankle, right elbow, and dorsolumbar region of 2 months' evolution. The following laboratory studies were within normal limits: complete blood cell count, C-reactive protein (CRP), latex, antistreptolysin, and antinuclear antibodies. Rheumatoid factor was negative and an increase in the erythrocyte sedimentation rate (ESR) was detected (56 mm/h). The pediatric department made an initial diagnosis of juvenile rheumatoid arthritis, and treatment with acetylsalicylic acid at 100 mg/kg/day and naproxen at 10 mg/kg/day was started. A thick, yellowish toenail was diagnosed as onychomycosis. No mycologic investigations were performed. Intermittent episodes of painful arthritis of different joints were present. The radiographic features of the peripheral joints included: narrow joint spaces, articular erosions, soft tissue swelling, and diffuse bony demineralization. Characteristic bilateral sacroiliitis and a swollen tendon sheath on the left ankle were detected. At 11 years of age the nail changes had extended to five other toenails and to four fingernails, were yellow,brown in color, and showed marked subungual hyperkeratosis ( Figs 1, 2). The rest of the nails showed significant nail pitting. Trials of griseofulvin alternated with itraconazole in an irregular form for five consecutive years resulted in no clinical improvement, which prompted a consultation to our dermatology department. On three different occasions, KOH nail specimens were negative for fungus, but the presence of parakeratotic cells aroused the suspicion of psoriasis. A complete physical examination was negative for psoriatic skin lesions. A nail bed biopsy specimen was characteristic of nail psoriasis ( Fig. 3). Figure 1. Thickened nails with severe subungual hyperkeratosis in five fingernails Figure 2. Secondary deformity of nail plate. No "sausage" fingers were observed Figure 3. Light microscopic appearance of a nail biopsy specimen showing parakeratotic hyperkeratosis, elongation of interpapillary processes, and Munroe abscess (arrow) (hematoxylin and eosin stain, ×40) The following human leukocyte antigens (HLAs) were positive: A9, A10, B12, B27, Cw1, Bw4, DR6, DR7, DQ1, DQ2, and DR53. A diagnosis of juvenile psoriatic arthritis associated with nail psoriasis was made. Toenail involvement became so painful that walking became very difficult. Occlusive 40% urea in vaseline applied to the affected toenails for 48 h resulted in significant improvement. Currently, the patient is 20 years old with nail involvement, but no psoriatic skin lesions have ever been observed. [source]


    Interleukin-10 gene promoter polymorphism in Polish rheumatoid arthritis patients

    INTERNATIONAL JOURNAL OF IMMUNOGENETICS, Issue 4 2010
    A. Paradowska-Gorycka
    Summary Interleukin (IL)-10 is an important multifunctional cytokine with both anti-inflammatory and immunoregulatory effects in rheumatoid arthritis (RA). In the present study, we evaluated the frequency and potential impact of IL-10 promoter polymorphisms on susceptibility to and severity of RA in Polish in , patients with a high disease activity (mean DAS 28 C-reactive protein 5.25). DNA was obtained from 244 RA patients and 106 healthy controls. The ,592C/A and ,1082G/A IL-10 gene polymorphisms were amplified by polymerase chain reaction with restriction endonuclease mapping. The frequency of the IL-10-592CA, -592AA genotypes (respectively: 30% vs 5% and 7% vs 0%) and allele ,592A (37% vs 5%) were significantly higher in RA patients as compared with a control group. We did not find any association of the IL-10-592C/A genotype distribution with disease parameters, except for an increased ESR (erythrocyte sedimentation rate) in patients with the ,592CC genotype as compared with those with ,592CA or ,592AA genotypes (P = 0.01). The frequency of the IL-10-1082GG genotype was lower (P = 0.0001), and that of the IL-10-1082GA genotype was higher (P = 0.009) in RA patients comparing with the control group. In RA patients with ,1082GA or ,1082AA genotypes the time duration of the disease (P = 0.03), Health Assessment Questionnaire (HAQ) Score (P = 0.04) and PLT count (P = 0.001) were significantly increased as compared with subjects with ,1082GG genotype. Presented findings indicate that IL-10-592C/A and IL-10-1082G/A polymorphisms may be considered genetic risk factors for RA susceptibility and severity. [source]


    Variation in the matrix metalloproteinase-3, -7, -12 and -13 genes is associated with functional status in rheumatoid arthritis

    INTERNATIONAL JOURNAL OF IMMUNOGENETICS, Issue 2 2007
    S. Ye
    As matrix metalloproteinases (MMPs) play an important role in rheumatoid arthritis, we investigated whether variation in MMP genes was associated with functional disability in rheumatoid arthritis patients. A cohort of patients with seropositive rheumatoid arthritis were recruited and genotyped for the MMP1-1607 1G > 2G, MMP3-1612 5A > 6A, MMP7-153C > T, MMP7-181G > A, MMP12-82A > G and MMP13-77A > G polymorphisms. Genotypes were then analysed in relation to functional disability assessed by Steinbrocker index and Health Assessment Questionnaire (HAQ) score. We detected an association between the MMP13-77 A > G polymorphism and Steinbrocker index, with patients of the A/A genotype having higher score than patients of the A/G or G/G genotype (P = 0.005), and the association remained significant after adjusting for age, sex, erythrocyte sedimentation rate, presence of erosive disease, Ritchie score, prednisolone therapy and years of diagnosis (P = 0.003). We also observed a relationship of Steinbrocker index with the MMP3-1612 5A > 6A, MMP7-181 A > G and MMP12-82A > G polymorphisms (P = 0.082, P = 0.037 and P = 0.045). No association was detected between the MMP1-1607 1G > 2G and MMP7-153C > T polymorphisms and either Steinbrocker index or HAQ score. These results suggest that MMP3, MMP7, MMP12 and MMP13 genotypes may play a role in determining functional status of rheumatoid arthritis. [source]


    Evaluation of Ves-Matic Cube 200 , an automated system for the measurement of the erythrocyte sedimentation rate

    INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 1p2 2010
    E. PEROVIC
    Summary Ves-Matic Cube 200 is fully automated analyzer that performs erythrocyte sedimentation rate (ESR) measurement using the standard ethylenediaminetetraacetic acid blood sample tube, thus markedly reducing the analytical time and avoiding the need for an extra blood sample. The aim of this study was to assess the automatic Ves-Matic Cube 200 system for the measurement of ESR in comparison with the original International Council for Standardization in Hematology reference method (Westergren). The evaluation comprised accuracy which was established using a 95% confidence interval (CI) for the mean difference between Ves-Matic Cube 200 and Westergren method (mean of difference: 0.47 ± 6.84 mm/h; 95% CI: ,0.376 to 1.325 mm/h), within-run imprecision for samples with ESR values of 9, 42 and 95 mm/h (coefficients of variation: 9.19%, 13.88% and 5.66%, respectively) and method comparison (, = 0.95; Passing-Bablok regression equation: Y = ,0.0435 + 1.0435 X; bias: ,0.5; limits of agreement: ,13.9 to 12.9). Stability was estimated after 24 h storage either at 4 °C and room temperature (mean of differences: ,1.91 mm/h; 95% CI: ,4.852 to 1.037 mm/h and mean of differences: ,12.48 mm/h; 95% CI: ,16.580 to ,8.390 mm/h, respectively). The obtained results suggest that the Ves-Matic Cube 200 automated analyzer is reliable system for the measurement of ESR in clinical laboratories. [source]


    Quality counts: new parameters in blood cell counting

    INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 3 2009
    C. BRIGGS
    Summary Recently several parameters have been introduced to the complete blood count such as nucleated red blood cells, immature granulocytes; immature reticulocyte fraction, immature platelet fraction and red cell fragments as well as new parameters for detection of functional iron deficiency. Leucocyte positional parameters, which may diagnose specific diseases (e.g. differentiate between abnormal lymphocytes in leukaemia and viral conditions and may also detect malarial infection) are now available. At this time they are only used for research; however, generally such parameters later become reportable. One manufacturer's routine analyser allows measurement of cells by flow cytometry using monoclonal antibodies. Currently, there are no accredited external quality assessment schemes (EQAS) for these parameters. For a number of parameters, on some instruments, there is no internal quality control, which brings into question whether these parameters should be used for clinical decision making. Other more established parameters, such as mean platelet volume, red cell distribution width and the erythrocyte sedimentation rate do not have EQAS available. The UK National EQAS for General Haematology held a workshop earlier this year in 2008 to discuss these parameters. Participants were asked to provide a consensus opinion on which parameters are the most important for inclusion in future haematology EQAS. [source]


    Improved preoperative iron status assessment by soluble transferrin receptor in elderly patients undergoing knee and hip replacement

    INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 6 2006
    M. BASORA
    Summary A poor preoperative haemoglobin (Hb) status is frequently encountered among adult patients scheduled for corrective surgery of the locomotive system, representing the main risk factor for blood transfusion. The soluble transferrin receptor (sTfR) has become a highly specific parameter for the detection of iron deficits as it can differentiate between iron deficiency anaemia and anaemia of chronic disease, because of the lack of effect by associated inflammation, unlike ferritin. The objectives of this study were to evaluate patients with the prevalence of risk for transfusion, the effect of inflammation on ferritin (F) values and functional iron deficiency in elderly patients with advanced degenerative arthropathy scheduled for hip or knee replacement. This observational, prospective study included patients over 50 years, operated for hip or knee replacements between April and June 2004. Of 218 patients studied, 87 (39%) presented with Hb levels between 10 and 13 g/dl. The prevalence of functional iron deficit was 27% (sTfR > 1.76 mg/l), while only 8.6% of patients displayed F levels below normal. As expected, C-reactive protein levels were elevated in 24.8% of patients and erythrocyte sedimentation rate was elevated in 50%. These inflammatory markers did not correlate with levels of either F or sTfR. Multiple factors can affect F levels, such as the inflammatory status of osteoarthritis in the elderly, obesity, nonsteroidal anti-inflammatory drugs therapy and low physical performance. As sTfR is not affected by inflammation, it has emerged as a primary parameter for the evaluation of iron status during preoperative assessment among patients scheduled for arthroplasty surgery. Our data strongly suggest that sTfR measurement contributes to improve patient management. [source]


    The erythrocyte adhesiveness/aggregation test for the detection of an acute phase response and for the assessment of its intensity

    INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 4 2002
    N. Maharshak
    Summary We have developed a simple slide test and image analysis to reveal the state of erythrocyte adhesiveness/aggregation in the peripheral blood of patients with various degrees of the humoral acute phase response. The significant correlation between the results of the erythrocyte adhesiveness/aggregation test (EAAT), the erythrocyte sedimentation rate and fibrinogen concentration support the notion that it is possible to use the EAAT as a marker for the intensity of the acute phase response. Within a group of 860 individuals, we were able to differentiate effectively between groups of patients with a different intensity of humoral acute phase response. The present study confirms previous observations that support the applicability of the EAAT to routine clinical practice. [source]


    Infectious discitis in adults: 9 years experience from Al-Yarmouk Teaching Hospital in Baghdad, Iraq

    INTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 2 2008
    Riyadh A. SAKENI
    Abstract Aim:, The objective of this study was to analyse the presentation, aetiology, diagnosis, management, and outcome of infectious discitis. Methods:, A screening prospective case-finding study was carried out at Al-Yarmouk teaching hospital in Baghdad, Iraq from 1997 to 2006. Fifty adult patients (12 men and 38 women) were diagnosed with infectious discitis from different referral sources. The diagnosis was based on laboratory biochemical tests, isolation of micro-organisms from blood and needle aspiration tissue, and radiological investigations including magnetic resonance images (MRI). Results:, Of the 50 cases, 32 (64%) patients presenting within 4 weeks, 94% had pelvic and abdominal surgical interventions, 70% presented with severe neck pain and 36% had neurological deficits. Marked elevation of erythrocyte sedimentation rate and high serum C-reactive protein levels were observed in all patients. Positive blood, percutaneous disc aspiration and surgical exploration samples for Staphylococcus aureus, Streptococcus viridans, E. coli, Pseudomonas aureginosa and Candida albicans were found. Radiological images showed that disc involvement did not exceed more than one intervertebrate disc with two adjacent vertebrae. The clinical outcome was full recovery (86%), residual neurological deficits (10%) and death (4%). Conclusions:, Infectious discitis in adults should be suspected in every case presenting with severe neck or back pain, followed by pelvic or abdominal surgical interventions. Therefore, MRI techniques should be performed on every case and an early empirical antibiotic therapy is advised. [source]


    The Debrecen Stroke Database: demographic characteristics, risk factors, stroke severity and outcome in 8088 consecutive hospitalised patients with acute cerebrovascular disease

    INTERNATIONAL JOURNAL OF STROKE, Issue 5 2009
    D. Bereczki
    Background High stroke mortality in central,eastern European countries might be due to higher stroke incidence, more severe strokes or less effective acute care than in countries with lower mortality rate. Hospital databases usually yield more detailed information on risk factors, stroke severity and short-term outcome than population-based registries. Patients and methods The Debrecen Stroke Database, data of 8088 consecutively hospitalised patients with acute cerebrovascular disease in a single stroke centre in East Hungary between October 1994 and December 2006, is analysed. Risk factors were recorded and stroke severity on admission was scored by the Mathew stroke scale. The modified Glasgow outcome scale was used to describe patient condition at discharge. Results Mean age was 68±13 years, 11·4% had haemorrhagic stroke. The rate of hypertension on admission was 79% in men, and 84% in women, 40·3% of men and 19·8% of women were smokers, and 34% of all patients had a previous cerebrovascular disease in their history. Case fatality was 14·9%, and 43% had some disability at discharge. Outcome at discharge was worse with higher age, higher glucose, higher blood pressure, higher white cell count and erythrocyte sedimentation rate and more severe clinical signs on admission. In multivariate analysis admission blood pressure lost its significance in predicting outcome. Conclusions In this large Hungarian stroke unit database hypertension on admission, smoking and previous cerebrovascular disease were more frequent than in most western databases. These findings indicate major opportunities for more efficient stroke prevention in this and probably other eastern European countries. [source]


    The Schnitzler syndrome: Chronic urticaria and monoclonal gammopathy , an autoinflammatory syndrome?

    JOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 8 2008
    Elisabeth Eiling
    Summary Schnitzler syndrome describes the simultaneous occurrence of monoclonal gammopathy and chronic urticaria with at least two additional minor symptoms (arthralgia, bone pain, fever of uncertain origin, hepato- or splenomegaly, lymphadenopathy, increased erythrocyte sedimentation rate, leukocytosis/thrombocytosis or increased bone density). Schnitzler syndrome is not wellknown and very likely under-recognized. Comprehensive diagnostic examinations are necessary to rule out other diseases, especially those of hematologic origin. Close interdisciplinary collaboration is mandatory. The etiology of Schnitzler syndrome is unclear, but the rapid response to the interleukin-1 receptor inhibitor anakinra underlines the pivotal role which the proinflammatory cytokine interleukin-1 may play in the pathophysiology of this potentially autoinflammatory disorder.
