Selected AbstractsStratified analyses for selecting appropriate target patients with diabetic peripheral neuropathy for long-term treatment with an aldose reductase inhibitor, epalrestatDIABETIC MEDICINE, Issue 7 2008N Hotta Abstract Aims The long-term efficacy of epalrestat, an aldose reductase inhibitor, in improving subjective symptoms and nerve function was comprehensively assessed to identify patients with diabetic peripheral neuropathy who responded to epalrestat treatment. Methods Stratified analyses were conducted on data from patients in the Aldose Reductase Inhibitor,Diabetes Complications Trial (ADCT). The ADCT included patients with diabetic peripheral neuropathy, median motor nerve conduction velocity , 40 m/s and with glycated haemoglobin (HbA1c) , 9.0%. Longitudinal data on HbA1c and subjective symptoms of the patients for 3 years were analysed (epalrestat n = 231, control subjects n = 273). Stratified analyses based on background variables (glycaemic control, grades of retinopathy or proteinuria) were performed to examine the relationship between subjective symptoms and nerve function. Multiple logistic regression analyses were conducted. Results Stratified subgroup analyses revealed significantly better efficacy of epalrestat in patients with good glycaemic control and less severe diabetic complications. In the control group, no improvement in nerve function was seen regardless of whether symptomatic benefit was obtained. In the epalrestat group, nerve function deteriorated less or improved in patients whose symptoms improved. The odds ratio of the efficacy of epalrestat vs. control subjects was approximately 2 : 1 (4 : 1 in patients with HbA1c , 7.0%). Conclusion Our results suggest that epalrestat, an aldose reductase inhibitor, will provide a clinically significant means of preventing and treating diabetic neuropathy if used in appropriate patients. [source] Prevention of secondary stroke and transient ischaemic attack with antiplatelet therapy: the role of the primary care physician roleINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 10 2007H. S. Kirshner Summary Background:, Stroke risk is heightened among patients who have had a primary stroke or transient ischaemic attack (TIA). The primary care physician is in the best position to monitor these patients for stroke recurrence. Because stroke recurrence can occur shortly after the primary event, guidelines recommend initiating antiplatelet therapy as soon as possible. Aspirin, with or without extended-release dipyridamole (ER-DP), and clopidogrel are options for such patients. Low-dose aspirin (75,150 mg/day) has the same efficacy as higher doses but with less gastrointestinal bleeding. Clopidogrel remains an option for prevention of secondary events and may benefit patients with symptomatic atherothrombosis, but its combined use with aspirin can harm patients with multiple risk factors and no history of symptomatic cerebrovascular, cardiovascular or peripheral vascular disease. Results:, Low dose aspirin is effective in secondary stroke prevention. Trials assessing aspirin plus ER-DP have shown that the combination is more effective than aspirin monotherapy in preventing stroke, with efficacy increasing among higher risk patients, notably those with prior stroke/TIA. Clopidogrel does not appear to have as much advantage over aspirin in secondary stroke prevention as aspirin plus ER-DP. Smoking cessation and cholesterol, blood glucose and blood pressure control are also important concerns in preventing recurrent stroke. In choosing pharmacological therapy, the physician must consider the individual patient's risk factors and tolerance, as well as other issues, such as use of aspirin among patients with ulcers. Conclusion:, Antiplatelet therapy is effective in secondary stroke prevention. Low dose aspirin can be used first-line, but aspirin plus ER-DP improves efficacy. Clopidogrel is another option in secondary stroke prevention, especially for aspirin-intolerant patients, but it appears to have less advantage over aspirin than aspirin plus ER-DP, and its combined use with aspirin has only marginally better efficacy and increased bleeding risk. [source] A double blind, randomized, placebo controlled study to evaluate the efficacy of erythromycin in patients with knee effusion due to osteoarthritisINTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 1 2009Shahram SADREDDINI Abstract Objective:, The efficacy of erythromycin in treatment of knee effusion due to osteoarthritis was evaluated. Method:, We assessed efficacy and safety of erythromycin during 16 weeks in patients enrolled in a randomized double-blind study. One hundred and eight patients with knee effusion due to osteoarthritis (OA) received 12-week courses of erythromycin or placebo allocated randomly, and were followed for 4 months. Acetaminophen 650 mg/day was used in both groups, while they received no other anti-inflammatory drugs (such as corticosteroid or nonsteroidal anti-inflammatory drugs) during the course of the study. Our patients were divided in two groups, erythromycin in doses of 200 mg four times per day was given to the first group (51 patients) over the first 3 months of the study and in the second group we used placebo with the same dosage and schedule (53 patients). Outcomes improvement for the erythromycin-treated group was assessed by a significantly higher mean score from baseline to the end of the trial, compared with placebo group. Patients were examined monthly during the treatment period. Measurement values included recording of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire subscales (pain, stiffness and function), range of motion and knee circumference. Results:, Erythromycin produced a higher response rate than placebo in treatment of knee effusion due to OA. Significant reduction in knee circumference (P < 0.0005) and pain (P < 0.001) with functional improvement (P < 0.0005) were seen. At the first month after treatment, 11.8% (6 patients) in erythromycin and 9.4% (5 patients) in placebo groups had 50% pain reduction, which was not significant (P = 0.75). At the fourth month, 50% reduction of pain was seen in 45.1% (23 patients) of the erythromycin and 11.3% (6 patients) of the placebo group. This was statistically significant (P < 0.0005). Erythromycin treatment was well tolerated and mild adverse events caused no discontinuation during the study. Conclusion:, This is a placebo-controlled study of macrolid efficacy on knee effusion due to OA in a short period. Results of this research showed the better efficacy of erythromycin in controlling effusion and pain with functional improvement in patients with knee effusion due to OA. [source] Efficacy and Safety of Rofecoxib 12.5 mg Versus Nabumetone 1,000 mg in Patients with Osteoarthritis of the Knee: A Randomized Controlled TrialJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2004Alan J. Kivitz MD Objectives: To evaluate the use of starting doses of rofecoxib and nabumetone in patients with osteoarthritis (OA) of the knee. Design: A 6-week, randomized, parallel-group, double-blind, placebo-controlled study. Setting: One hundred thirteen outpatient sites in the United States. Participants: A total of 1,042 male and female patients aged 40 and older with OA of the knee (>6 months). Interventions: Rofecoxib 12.5 mg once a day (n=424), nabumetone 1,000 mg once a day (n=410), or placebo (n=208) for 6 weeks. Measurements: The primary efficacy endpoint was patient global assessment of response to therapy (PGART) over 6 weeks, which was also specifically evaluated over the first 6 days. The main safety measure was adverse events during the 6 weeks of treatment. Results: The percentage of patients with a good or excellent response to therapy as assessed using PGART at Week 6 was significantly higher with rofecoxib (55.4%) than nabumetone (47.5%; P=.018) or placebo (26.7%; P<.001 vs rofecoxib or nabumetone). Median time to first report of a good or excellent PGART response was significantly shorter in patients treated with rofecoxib (2 days) than with nabumetone (4 days, P=.002) and placebo (>5 days, P<.001) (nabumetone vs placebo; P=.007). The safety profiles of rofecoxib and nabumetone were generally similar, including gastrointestinal, hypertensive, and renal adverse events. Conclusion: Rofecoxib 12.5 mg daily demonstrated better efficacy over 6 weeks of treatment and quicker onset of OA efficacy over the first 6 days than nabumetone 1,000 mg daily. Both therapies were generally well tolerated. [source] Lactobionic acid in a natural alkylpolyglucoside-based vehicle: assessing safety and efficacy aspects in comparison to glycolic acidJOURNAL OF COSMETIC DERMATOLOGY, Issue 1 2010Marija Tasic-Kostov BSc Summary Background/aims, Lactobionic acid (LA) is a newer cosmeceutical active belonging to the class of alpha-hydroxyacids (AHAs), showing advantages over them. The aim of part I of this study was to compare efficacy and irritation potential of LA vs. glycolic acid (GA) from two types of vehicles , gel and emulsion. In part II, effects of LA-containing emulsions based on a new, natural emulsifier of alkylpolyglucoside (APG) type were evaluated. Methods, Skin bioengineering was used on 77 healthy volunteers to assess: color as erythema and melanin (MI) index, transepidermal water loss, electrical capacitance and pH of the skin. In part I of the study, the parameters were measured after occlusion and periodically during 2 weeks of test samples application; in part II parameters were measured periodically during 4 weeks. Results/conclusion, LA-containing samples has produced better skin performance when compared with corresponding GA-containing ones, particularly the lack of both skin irritation and skin barrier impairment. When used in vehicles based on a new APG-emulsifier, LA and GA have shown better efficacy, emphasizing the importance of vehicle on the effects of topical actives. LA (6%) in the emulsion based on APGs could be proposed as an alternative to low-molecular AHAs in cosmeceuticals. [source] Infliximab improves inflammation and anthropometric measures in pediatric Crohn's diseaseJOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 4 2010Daniel M Sinitsky Abstract Background and Aim:, Infliximab (IFX) is a monoclonal antibody licensed to treat medically refractory Crohn's disease (CD). Our aim was to elucidate the effects of IFX therapy on clinical, growth and serum parameters in children with CD in a single pediatric center in Sydney, Australia. Methods:, A retrospective case series review of children treated with IFX for CD at Sydney Children's Hospital, Australia was undertaken, with a review of outcomes after starting IFX. Main outcome measures were response and remission (as measured according to improvements in Pediatric Crohn's Disease Activity Index scores and Physician Global Assessment), laboratory markers (C-reactive protein, erythrocyte sedimentation rate, hemoglobin, white cell count, lymphocytes, neutrophils, platelets, albumin) and growth (Z scores). Results:, The 16 patients included had a mean age at first infusion of 13.0 years (1.25,17.5 years). Six of 12 patients (with adequate data available) were in remission at 2 weeks following the first infusion. At 1 year, 10 of 12 patients (83%) were in remission. Mean C-reactive protein and erythrocyte sedimentation rate had fallen significantly (P < 0.05) at 2 weeks (from 29 to 7 mg/L and 40 to 19 mm/h, respectively). Positive trends were observed for all other parameters, excluding lymphocytes and white cell count. At 1 year, mean Z score for body mass index improved significantly from ,0.9 to ,0.1 (P < 0.01). Conclusions:, Disease activity subsides in most children treated with IFX for CD. IFX therapy also improves some growth parameters. The pattern of improvement requires further elucidation, as the results in the present study suggest differing dosing frequency of infusion may achieve better efficacy. [source] Alternate delivery route for amifostine as a radio-/chemo-protecting agentJOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 7 2008Natalie P. Praetorius Amifostine (ethiofos, WR-2721) is an organic thiophosphate prodrug that serves as an antineoplastic adjunct and cytoprotective agent useful in cancer chemotherapy and radiotherapy. The selective protection of certain tissues of the body is believed to be due to higher alkaline phosphatase activity, higher pH and vascular permeation of normal tissues. Amifostine is conventionally administered intravenously before chemotherapy or radiotherapy. It is approved by the Food and Drug Administration (FDA) to reduce cumulative renal toxicity associated with repeated administration of cisplatin in patients with advanced ovarian cancer. It was originally indicated to reduce the cumulative renal toxicity from cisplatin in non-small cell lung cancer although this indication was withdrawn in 2005. Amifostine is also FDA approved for patients with head and neck cancer to reduce the incidence of moderate to severe xerostomia in patients who are undergoing postoperative radiation treatment where the radiation port includes a substantial portion of the parotid glands. The potential of amifostine as a cytoprotective agent is unlikely to be fully realized if the method of administration is restricted to intravenous administration. Attempts have been made to develop non-invasive methods of delivery such as transdermal patches, pulmonary inhalers, and oral sustained-release microspheres. It is the goal of this article to explore non-intravenous routes of administration associated with better efficacy of the drug. This review will primarily focus on the variety of more recently studied (2002 and later) alternative modes for amifostine administration, including subcutaneous, intrarectal and oral routes. [source] The tolerance and efficacy of a postponed retreatment with infliximab in Crohn's disease primary respondersALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 12 2009D. LAHARIE Summary Background, In Crohn's disease (CD) patients naïve to immunomodulators primary responding to infliximab (IFX) induction, maintenance with scheduled IFX or with immunomodulators is possible. The benefit of additional IFX infusions after failure of maintenance with immunomodulators is not known. Aim, To assess the efficacy and factors associated with efficacy of postponed IFX retreatment. Methods, All CD primary responders to an IFX induction regimen in maintenance with immunomodulators were retrospectively included when they received at least one additional IFX infusion after week 14. Efficacy was defined as clinical response at week 4 and absence of intolerance leading to discontinuation. Results, Sixty-one patients were retreated with IFX with a 38-week median time from induction. Efficacy was achieved in 80% patients. Twelve patients had no clinical benefit: seven acute hypersensitivity reactions and five loss of response. By multivariate analysis, the only factor associated with no efficacy was a median time >50 weeks from induction to retreatment (odds ratio = 7.38; 95%CI: 1.38,39.59; P = 0.02). Conclusion, Postponed retreatment with IFX in CD primary responders should be administered within 50 weeks after induction, for better efficacy and tolerance. [source] REVIEW: Preventing mother-to-child transmission of HIV: successes and challengesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 9 2005James McIntyre Mother-to-child transmission of HIV continues to be a major cause of infant morbidity and mortality in resource-poor settings. Intrapartum and postpartum nevirapine-based regimens have been introduced in many settings. New research has shown that better efficacy can be achieved with the addition of single-dose nevirapine to short course zidovudine regimens, and that selection of nevirapine-resistant virus can be reduced with a short postpartum combination antiretroviral cover. Women who need antiretroviral therapy for their own health should receive it in pregnancy, and access for pregnant women needs to be expanded urgently. The reduction of transmission through breastfeeding remains a challenge. [source] Pulsed dye laser vs. intense pulsed light for port-wine stains: a randomized side-by-side trial with blinded response evaluationBRITISH JOURNAL OF DERMATOLOGY, Issue 2 2009A. Faurschou Summary Background, Pulsed dye lasers (PDLs) are considered the treatment of choice for port-wine stains (PWS). Studies have suggested broadband intense pulsed light (IPL) to be efficient as well. So far, no studies have directly compared the PDL with IPL in a randomized clinical trial. Objectives, To compare efficacy and adverse events of PDL and IPL in an intraindividual randomized clinical trial. Methods, Twenty patients with PWS (face, trunk, extremities; pink, red and purple colours; skin types I,III) received one side-by-side treatment with PDL (V-beam Perfecta, 595 nm, 0·45,1·5 ms; Candela Laser Corporation, Wayland, MA, U.S.A.) and IPL (StarLux, Lux G prototype handpiece, 500,670 and 870,1400 nm, 5,10 ms; Palomar Medical Technologies, Burlington, MA, U.S.A.). Settings depended on the preoperative lesional colour. Treatment outcome was evaluated by blinded, clinical evaluations and by skin reflectance measurements. Results, Both PDL and IPL lightened PWS. Median clinical improvements were significantly better for PDL (65%) than IPL (30%) (P = 0·0004). A higher proportion of patients obtained good or excellent clearance rates with the PDL (75%) compared with IPL (30%) (P = 0·0104). Skin reflectance also documented better results after PDL (33% lightening) than IPL (12% lightening) (P = 0·002). Eighteen of 20 patients preferred to receive continued treatments with PDL (P = 0·0004). No adverse events were observed with PDL or IPL. Conclusions, Both the specific PDL and IPL types of equipment used in this study lightened PWS and both were safe with no adverse events. However, the PDL conveyed the advantages of better efficacy and higher patient preference. [source] Critical review of oral drug treatments for diabetic neuropathic pain,clinical outcomes based on efficacy and safety data from placebo-controlled and direct comparative studiesDIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 3 2005Hugo Adriaensen Abstract The present review aims to evaluate the efficacy and safety of a selection of oral treatments for the management of painful diabetic neuropathy. A literature review was conducted retrieving placebo-controlled and direct comparative studies with a selection of oral treatments for painful diabetic neuropathy. All studies were analyzed with regard to efficacy and tolerability. Efficacy was evaluated as the percentage improvement in pain intensity between baseline and endpoint. Tolerability was evaluated by means of study discontinuations due to adverse events and by incidence of drug-related adverse events. The analyzed trials enrolled different patient populations with mostly small numbers of patients. The great variability in dosages and dose titration schemes, cross-over designs with variable wash-out periods, and other design schemes made comparison between the different studies difficult. Gabapentin, lamotrigine, tramadol, oxycodone, mexiletine, and acetyl-L-carnitine were the only treatments studied in large (at least 100 patients), placebo-controlled parallel group trials. It is concluded that standardization in design and reporting for comparison of treatments is needed. Validated questionnaires for evaluation of the efficacy and safety should be further developed. Based on the reviewed randomised controlled trials, gabapentin shows good efficacy, a favourable side-effect profile with lack of drug interactions and therefore it may be a first choice treatment in painful diabetic neuropathy, especially in the elderly. However, head to head trials of current treatments are lacking and therefore randomized controlled trials are required to address this issue. Copyright © 2005 John Wiley & Sons, Ltd. [source] An open-label trial of Korean red ginseng as an adjuvant treatment for cognitive impairment in patients with Alzheimer's diseaseEUROPEAN JOURNAL OF NEUROLOGY, Issue 8 2008J.-H. Heo Background and purpose:, Ginseng is one of the most popular herbs worldwide. Ginseng has various medical applications, and it seems to have significant effects as a cognition-enhancing drug. In this study, we examined the efficacy of Korean red ginseng (KRG) as an adjuvant therapy to conventional anti-dementia medications in patients with Alzheimer's disease. Methods:, The trial was designed as a 12-week randomized study. Sixty-one patients (24 males and 37 females) with Alzheimer's disease were randomly assigned to one of the following treatment groups: low-dose KRG (4.5 g/day, n = 15), high-dose KRG (9 g/day, n = 15) or control (n = 31). The Alzheimer's Disease Assessment Scale (ADAS), Korean version of the Mini-Mental Status Examination (K-MMSE) and Clinical Dementia Rating (CDR) scale were used to assess the change in cognitive and functional performance at the end of the 12-week study period. Results:, The patients in the high-dose KRG group showed significant improvement on the ADAS and CDR after 12 weeks of KRG therapy when compared with those in the control group (P = 0.032 and 0.006 respectively). The KRG treatment groups showed improvement from baseline MMSE when compared with the control group (1.42 vs. ,0.48), but this improvement was not statistically significant. Conclusions:, KRG showed good efficacy for the treatment of Alzheimer's disease; however, further studies with larger samples of patients and a longer efficacy trial should be conducted to confirm the efficacy of KRG. [source] Tianeptine and paroxetine in major depressive disorder, with a special focus on the anxious component in depression: an international, 6-week double-blind study,HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 3 2001Jean Pierre Lepine Abstract Tianeptine (37.5,mg/day) and paroxetine (20,mg/day) were compared in a population of depressive patients without past or current history of co-morbid anxiety and/or important anxiolytic treatment. In a 6-week, double blind trial, the special focus was on anxious symptoms. Both drugs showed good efficacy on depressive symptomatology, assessed with MADRS and HDRS, but no difference was detected between tianeptine and paroxetine, for any assessment criterion. Despite the choice of selected depressive patients, without any co-morbid anxious disorder, anxiety scale scores at inclusion (HAMA and BAS) were appreciable but correlated poorly with depressive scores. Both tianeptine and paroxetine improved the apparent anxious component in depression. Tolerability of both drugs was good, although significantly better with tianeptine. Thus tianeptine and paroxetine are effective and safe treatments for major depression and may also act directly on the anxious component of the psychopathology.

Amyloidotic polyneuropathies may be genetic in their origin or present in association with a number of chronic inflammatory dysimmune disorders. We report on three patients affected by predominantly sensitive polyneuropathy, monoclonal gammopathy and amyloidosis. Patient 1. Woman, 72 years old, with a one year history of painful paraesthesias, ataxic gait and demyelinating predominantly sensitive polyneuropathy at 4 limbs also with involvement of sympathetic fibres. Blood protein electrophoresis showed a monoclonal gammopahty (IgG-k) with normal bone marrow biopsy and positivity for amyloid at fat biopsy. The patient has been treated with melphalan 0.2 mg/Kg/day+prednisone 100 mg/day for 7 days each month for 6 months with good efficacy and only a transient reduction in platelet and white blood cells count. Patient 2. Man, 60 years old, new diagnosis of diabetes with a 9 month history of painful paraesthesias and hyposthenia, a demyelinating sensory-motor polyneuropathy at 4 limbs. The patient presented an IgG-, monoclonal gammopathy with normal bone marrow biopsy, fat biopsy but not sural nerve biopsy positive for amyloid. The patient underwent melphalan+prednisone therapy, with insulinic control of glycemia. He presented a clear-cut improvement in sensitive-motor symptomatology. Patient 3. Man, 72 years old, with a 15 year history of ulcerous rectocolites. Since 1998 started complaining of paraesthesias and disaesthesias at four limbs associated with gait disturbances. The patient presented an IgG-, monoclonal gammopathy with normal bone marrow aspiration and elevated serum Interleukin-6 levels, fat biopsy positive for amyloid, and high anti-MAG antibodies titer (1:100000). Because of RCU, melphalan therapy was excluded and the patient is at the moment under fludarabine (25 mg/m2/day) ev for 5 days each 6 weeks for 6 bouts. [source] Annotation: The use of psychotropic medications in children: an American viewTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 2 2003Mark L. Wolraich Background: Psychotropic medications have become an integral component in the treatment of children with mental illnesses. Methods: Selective reviews of the empirical evidence for the efficacy of psychotropic medications and studies of their use patterns were reviewed. Results: Very strong efficacy for at least the short-term benefits and safety of stimulant medications was found and some good efficacy and safety evidence for the treatment of anxiety and depressive disorders with seratonin reuptake inhibitors (SSRI) was also found. Efficacy for tricyclic antidepressants to treat attention deficit hyperactivity disorder was found but the presence of significant side effects makes them less the drugs of choice. Other medications are presented but with less rigorous evidence. Studies of use found that stimulant medications are extensively prescribed in the US by both psychiatrists and primary care physicians. SSRI are also prescribed extensively but not to the extent of stimulants and are more frequently prescribed by psychiatrists. Conclusions: There is now good evidence for the efficacy of some psychotropic agents and their use is an integral component in the management of childhood mental illnesses. [source] Photodynamic therapy using light-emitting diodes for the treatment of viral wartsTHE JOURNAL OF DERMATOLOGY, Issue 10 2009Akiko OHTSUKI Abstract Photodynamic therapy with topical 5-aminolevulinic acid is an effective and safe treatment for actinic keratosis and superficial non-melanoma skin cancer. Further, some studies have reported good efficacy when using photodynamic therapy to treat viral warts. The light-emitting diode is an incoherent, narrow-spectrum light source. The purpose of this study is to evaluate the efficacy of photodynamic therapy using a light-emitting diode for viral warts. Six patients with a total of 41 foot and hand warts were recruited in this study. They were treated with 20% 5-aminolevulinic acid cream under occlusion for 5 h. Thereafter, the treated area was irradiated with the light from a red light-emitting diode (633 ± 6 nm) with a dose of 126 J/cm2. This treatment was repeated at 2- or 3-week intervals. The rate of improvement observed in patients was 68.3%. The adverse effects included mild to moderate pain and erythema, which was well-tolerated by all six patients. No patients withdrew from the study due to the adverse effects. Photodynamic therapy with topical 5-aminolevulinic acid using the light from a red light-emitting diode has the advantage of non-invasiveness, minimal associated adverse reactions, and production of good results in a significant proportion of cases: therefore, it is an alternative treatment for recalcitrant viral warts. [source] Efficacy of traditional and biologic agents in different clinical phenotypes of adult-onset Still's diseaseARTHRITIS & RHEUMATISM, Issue 8 2010Stefano Franchini Objective To evaluate the efficacy of antiinflammatory agents, steroids, immunosuppressants, and biologic agents in patients with adult-onset Still's disease (AOSD) who have either chronic articular disease or nonchronic disease. Methods Forty-five patients with AOSD were seen and followed up for at least 2 years at our institution, from 1991 to 2008. The majority of patients were treated with several therapeutic regimens; a total of 152 efficacy trials were administered. Data regarding the type of medication, the dosage used, and the outcome of these trials were collected and analyzed. Results Our data showed that the efficacy of monotherapy with a nonsteroidal antiinflammatory drug was very low (16%) and confirmed good efficacy of steroid therapy (63%), particularly in patients without chronic articular disease (78%). Patients whose disease did not respond to steroid therapy at the time of disease onset were at risk of the subsequent development of chronic arthritis. Disease-modifying antirheumatic drug (DMARD) monotherapy was successful in controlling steroid-resistant or steroid-dependent disease in 60% of patients. Methotrexate and cyclosporine showed the best response rates. The combination of high-dose steroids and cyclosporine was administered to successfully control some acute life-threatening complications. Only 6 patients had disease that was both steroid resistant and DMARD resistant. Treatment with biologic agents eventually led to satisfactory control of disease manifestations in 5 (83%) of these 6 patients. Conclusion Steroids were less effective in patients with chronic articular disease than in those with nonchronic disease. The administration of DMARDs early after disease onset could be beneficial in patients with steroid-resistant disease who are at risk of the development of chronic articular disease. Biologic agents proved to be highly effective in both steroid-resistant and DMARD-resistant AOSD. [source] Aurothiomalate inhibits cyclooxygenase 2, matrix metalloproteinase 3, and interleukin-6 expression in chondrocytes by increasing MAPK phosphatase 1 expression and decreasing p38 phosphorylation: MAPK phosphatase 1 as a novel target for antirheumatic drugsARTHRITIS & RHEUMATISM, Issue 6 2010Riina Nieminen Objective Aurothiomalate is a disease-modifying antirheumatic drug that suppresses inflammation and retards cartilage degradation and bone erosion in arthritis. The molecular mechanisms of action of aurothiomalate are not known in detail. MAPK pathways are major signaling pathways in inflammation that regulate the production of many inflammatory and destructive factors in arthritis. The purpose of the present study was to investigate the effects of aurothiomalate on the activity of p38 MAPK and on the expression of MAPK phosphatase 1 (MKP-1), cyclooxygenase 2 (COX-2), matrix metalloproteinase 3 (MMP-3), and interleukin-6 (IL-6) in immortalized murine H4 chondrocytes and in intact human and murine cartilage. Methods Protein expression was examined by Western blotting or by enzyme-linked immunosorbent assay, and messenger RNA (mRNA) expression was examined by real-time reverse transcription,polymerase chain reaction analysis. The mediator role of MKP-1 was investigated by using small interfering RNA (siRNA) methods to down-regulated MKP-1 expression in chondrocytes in culture and by comparing the responses in intact cartilage from MKP-1,deficient and wild-type mice. The effects of aurothiomalate were also confirmed in human rheumatoid cartilage by using tissue samples obtained at the time of total knee replacement surgery. Results Aurothiomalate inhibited IL-1,,induced COX-2 expression and prostaglandin E2 production by destabilizing COX-2 mRNA, as did the p38 MAPK inhibitor SB203580. Interestingly, aurothiomalate also increased the expression of MKP-1 and reduced the IL-1,,induced phosphorylation of p38 MAPK. Knockdown of MKP-1 by siRNA significantly impaired the ability of aurothiomalate to inhibit the phosphorylation of p38 MAPK and the expression of COX-2, MMP-3, and IL-6. Likewise, aurothiomalate reduced COX-2, MMP-3, and IL-6 expression in articular cartilage from patients with rheumatoid arthritis, as well as in articular cartilage from wild-type mice but not from MKP-1,/, mice. Conclusion Our findings indicate a novel mechanism for the antiinflammatory and antierosive actions of aurothiomalate, through increased expression of MKP-1, which leads to reduced activation of p38 MAPK and suppressed expression of COX-2, MMP-3, and IL-6. The results suggest that manipulation of MKP-1 levels is a promising new mechanism to be directed in the search and development of novel antiinflammatory and antierosive compounds that have the good efficacy of gold compounds but not their toxicity. [source] Efficacy and tolerability of zonisamide as add-on in brain tumor-related epilepsy: preliminary reportACTA NEUROLOGICA SCANDINAVICA, Issue 3 2009M. Maschio Background,, Zonisamide (ZNS) is an antiepileptic drug (AED) with broad spectrum action that demonstrated a good efficacy in controlling seizures as add-on in adult and pediatric epilepsy. To date there have been no studies on ZNS in patients with brain tumor-related epilepsy (BTRE). Aim of the study,, To evaluate efficacy and tolerability of ZNS as add-on in BTRE. Methods, We followed six patients suffering from BTRE who had already been treated with other AEDs and who had had not experienced adequate seizure control. Three patients underwent chemotherapy while being treated with ZNS. Mean duration of follow-up was 8 months. Results,, Mean seizure number in the last month prior to the introduction of ZNS had been 27.7/month. ZNS mean dosage was of 283.3 mg/day. At last follow-up, the mean seizure number was reduced to 8.8/month. Responder rate was 83.3%. Two patients discontinued the drug because of side effects. There were no other reported side effects. Conclusions,, Preliminary data on the use of ZNS in add-on in patients with BTRE indicate that this drug may represent a valid alternative as add-on in this particular patient population. However, larger samples are necessary to draw definitive conclusions. [source] |
