    Lasthénie de Ferjol syndrome: a rare disease with fascinating history

    INTERNAL MEDICINE JOURNAL, Issue 5 2010
    M. Karamanou
    Abstract In our paper, we present the fascinating story of Lasthénie de Ferjol syndrome. A rare self-induced iron deficiency anaemia caused by surreptitious blood-letting. The French haematologist Jean Bernard first described the syndrome and named it after the heroine of Barbey d' Aurevilly's novel The Story without a Name. This factitious anaemia presents a great challenge for physicians even today, both in diagnosis and in therapy. [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]

    Nitric oxide and changes of iron metabolism in exercise

    BIOLOGICAL REVIEWS, Issue 4 2002
    ZHONG MING QIAN
    ABSTRACT Accumulated data imply that exercise itself might not lead to a true iron deficiency or ,sport anaemia' in a healthy athlete who has adequate iron intake. The higher prevalence of iron deficiency anaemia in younger female athletes might be not due to exercise itself, but probably results from dietary choices, inadequate iron intake and menstruation. These factors can also induce iron deficiency or anaemia in the general population. However, exercise does affect iron metabolism, leading to low or sub-optimal iron status. The underlying mechanism is unknown. In this review, recent advances in the study of the effect of exercise on iron metabolism and nitric oxide, and the relationship between nitric oxide and iron status in exercise are discussed. A hypothesis that increased production of nitric oxide might contribute to sub-optimal iron status in exercise is proposed. [source]

    Iron plus folate is more effective than iron alone in the treatment of iron deficiency anaemia in pregnancy: a randomised, double blind clinical trial

    BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 9 2002
    Jorge Juarez-Vazquez
    Objective To evaluate whether folate supplementation to iron is able to accelerate solving of iron deficiency anaemia in pregnancy. Design Multicentre, double blind, randomised clinical trial. Setting Nine hospital gynaecologic units located in Mexico. Population Three hundred seventy-one women with iron deficiency anaemia between 14 and 27 weeks of pregnancy. Methods Random allocation of the study population to receive 80 mg iron proteinsuccinylate, with or without 0.370 mg folinic acid daily for 60 days. Main outcome measure Haemoglobin concentration increase. Results Combined iron and folate therapy showed a better therapeutic response: the increase in haemoglobin levels from baseline was 1.42 (0.14) g/dL for women treated with both compounds vs 0.80 (0.125) g/dL for those given iron only (P < 0.001). A multivariable regression analysis showed that this effect was independent of basal levels of blood iron, ferritine and serum folate and was more evident in women with more severe anaemia. In the 64 women belonging to the subgroup defined by the per-protocol (PP) population and the lowest quartile of baseline haemoglobin values (mean 8.96, range 5.9,9.8 g/dL), the increase at day 60 was estimated 2.3 (0.53) g/dL for the combined therapy vs 0.5 (0.5) g/dL for iron only (P= 0.07). No significant differences in tolerability were observed between the two groups. Conclusion Folate supplementation is recommended in pregnant women with iron deficiency anaemia irrespective of the serum levels of folate. [source]

    The ratio of serum transferrin receptor and serum ferritin in the diagnosis of iron status

    BRITISH JOURNAL OF HAEMATOLOGY, Issue 1 2001
    Babatyi I. Malope
    Laboratory tests used in the diagnosis of iron status lack specificity in defining iron deficiency anaemia (IDA) and anaemia of inflammation (AI). The serum transferrin receptor (sTfR) may provide more information in this regard. The iron status of 561 pre-school children was determined and classified using the conventional measurements. The value of the concentration of sTfR, the ratio of sTfR (µg/ml) to LogSF (µg/l) (TfR-Index), and the Log of the ratio of sTfR (µg/l) to SF (µg/l) , (LogTfR:Fer ratio), in the classification of the iron status were determined by comparing their distributions across the classification of iron status. Although there were significant differences in sTfR and TfR-Index across the categories of iron status, there was considerable overlap. All subjects with iron deficiency had LogTfR:Fer ratio >,2·55, whereas in all subjects classified as AI it was < 2·55, thus clearly separating the two. The LogTfR:Fer ratio was not able to exclude IDA in the presence of inflammation. However, in cases of combined IDA and AI the LogTfR:Fer ratio was <,2·55 but increased to >,2·55 after resolution of the inflammation. This novel method of calculating the LogTfR:Fer ratio may provide a more precise classification of the iron status of children. [source]

    Blue rubber bleb nevus syndrome

    ACTA PAEDIATRICA, Issue 4 2010
    M Agnese
    Abstract Blue Rubber Bleb Nevus Syndrome (BRBNS) is a rare condition characterized by multiple venous malformations involving the skin and internal organs. The gastrointestinal tract is always involved and intestinal haemorrhage is the most frequent clinical manifestation associated with iron deficiency anaemia. We describe a 10-year-old girl who, since birth, presented numerous venous malformations all over her body and a lymphangioma in the right leg. At the age of 5 years, she also had a severe episode of gastric bleeding requiring a blood transfusion. From this episode, she is suffering from chronic anaemia and this is the reason for admission into our hospital. The endoscopic examination of the gastrointestinal tract revealed multiple giant venous malformations in the oesophagus, stomach, duodenum and in all visible sections of the colon. Endoscopy is the gold standard technique for the diagnosis of BRBNS with GI lesions and also allows immediate therapeutic measures such as argon plasma coagulation, laser photocoagulation, sclerotherapy or band ligation. In addition, pharmacological treatments based on corticosteroids, interferon alfa, vincristine or octreotide have been described for BRBNS. Conclusion:, Blue Rubber Bleb Nevus Syndrome is a congenital cutaneous and gastrointestinal haemangiomatosis. Its morbidity and mortality depends on involvement of visceral organs and particularly on GI bleeding. The treatment is based on pharmacological or surgical therapy. Overall, the most important step is the follow-up to the presence and the evolution of GI lesions and the possible bleeding. [source]

    Beta-cell, thyroid, gastric, adrenal and coeliac autoimmunity and HLA-DQ types in type 1 diabetes

    CLINICAL & EXPERIMENTAL IMMUNOLOGY, Issue 2 2001

    The autoimmune attack in type 1 diabetes is not only targeted to , cells. We assessed the prevalence of thyroid peroxidase (aTPO), parietal cell (PCA), antiadrenal (AAA) and endomysial antibodies (EmA-IgA), and of overt autoimmune disease in type 1 diabetes, in relation to gender, age, duration of disease, age at onset, ,-cell antibody status (ICA, GADA, IA2A) and HLA-DQ type. Sera from 399 type 1 diabetic patients (M/F: 188/211; mean age: 26 ± 16 years; duration: 9 ± 8 years) were tested for ICA, PCA, AAA and EmA-IgA by indirect immunofluorescence, and for IA2A (tyrosine phosphatase antibodies), GADA (glutamic acid decarboxylase-65 antibodies) and aTPO by radiobinding assays. The prevalence rates were: GADA 70%; IA2A, 44%; ICA, 39%; aTPO, 22%; PCA, 18%; EmA-IgA, 2%; and AAA, 1%. aTPO status was determined by female gender (, = , 1·15, P = 0·002), age (, = 0·02, P = 0·01) and GADA +,(, = 1·06, P = 0·02), but not by HLA-DQ type or IA2A status. Dysthyroidism (P < 0·0001) was more frequent in aTPO + subjects. PCA status was determined by age (, = 0·03, P = 0·002). We also observed an association between PCA + and GADA +,(OR = 1·9, P = 0·049), aTPO +,(OR = 1·9, P = 0·04) and HLA DQA1*0501-DQB1*0301 status (OR = 2·4, P = 0·045). Iron deficiency anaemia (OR = 3·0, P = 0·003) and pernicious anaemia (OR = 40, P < 0·0001) were more frequent in PCA + subjects. EmA-IgA + was linked to HLA DQA1*0501-DQB1*0201 + (OR = 7·5, P = 0·039), and coeliac disease was found in three patients. No patient had Addison's disease. In conclusion, GADA but not IA2A indicate the presence of thyrogastric autoimmunity in type 1 diabetes. aTPO have a female preponderance, PCA are weakly associated with HLA DQA1*0501-DQB1*0301 and EmA-IgA + with HLA DQA1*0501-DQB1*0201.

    Iron deficiency and iron deficiency anaemia during infancy and childhood

    ACTA PAEDIATRICA, Issue 4 2004
    Rolf Zetterströ
    The present definition of iron deficiency and iron deficiency anaemia is under debate. Our present figures for the prevalence of iron deficiency in infants and toddlers are thus disputed. Conclusion: Better understanding of the regulation of iron metabolism and requirement during the critical early period of growth and development is needed for relevant control of iron deficiency anaemia.
