- The effect of Neydharting mud-pack therapy on knee osteoarthritis: a randomized, controlled, double-blind follow-up pilot study. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 21.
The aim of this study was to evaluate the effects of Neydharting mud-pack therapy on the clinical parameters and quality of life in patients with knee osteoarthritis. In this double-blind, randomized, follow-up study on 53 patients with knee osteoarthritis, one group received hot mud-pack therapy, whereas the other (control) group was treated with hot packs of a substance manufactured on 10 occasions for 2 weeks. Western Ontario and McMaster Universities Arthritis Index (WOMAC), EuroQoL-5D quality-of-life measure and need for analgesics and non-steroidal anti-inflammatory drugs were recorded before treatment, at the end of treatment (at Week 2), and at Weeks 6 and 12. The WOMAC and the EQ5D quality-of-life scores improved from the baseline to the end of treatment in both groups, and further improvement was observed during the follow-up period (p < 0.001, respectively, in both groups). The need for medications for knee joint pain improved in both groups, and these changes were significant only in the mud-treated group (p < 0.001), but not in the control group (p = 0.106) compared to baseline. The number of patients requiring medications for knee joint pain showed a continuous downward trend at the subsequent post-treatment visits by the mud-treated group, and these changes became significant by Visit 4 compared to baseline (p = 0.016). The control group showed only temporary and not significant decrease. The difference was not significant between the groups in any of the outcome parameters at any visits. The Neydharting mud pack has a favorable effect on the clinical parameters, quality of life, and need for medications in patients with knee osteoarthritis. To evaluate the chemical effect, the number of patients should be increased.
- Anti-cyclic citrullinated peptide (anti-CCP) antibodies with brucellosis. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 18.
Anti-cyclic citrullinated peptide (anti-CCP) was positive in 11.5 % and rheumatoid factor was positive in 8.8 % of the patients with Brucella. After a comparative evaluation, we have found out that there was not a statistical significance concerning the anti-CCP levels between the patients with brucellosis and healthy control.
- Treatment of ankylosing spondylitis with TNF blockers: a meta-analysis. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 18.
Biological agents directed against tumor necrosis factor (TNF) represent therapeutic options for patients with ankylosing spondylitis with high disease activity despite use of non-steroidal anti-inflammatory drugs. To evaluate the efficacy and safety of the anti-TNF agents infliximab, etanercept, adalimumab, golimumab, and certolizumab for the treatment of ankylosing spondylitis, we performed a systematic review of randomized clinical trials on adult patients with ankylosing spondylitis using articles culled from the EMBASE, MEDLINE, Cochrane Controlled Trials Register and LILACS databases (September/2012), manual literature search, and the gray literature. Study selections and data collection were performed by two independent reviewers, with disagreements solved by a third reviewer. The following outcomes were evaluated: ASAS 20 response, disease activity, physical function, vertebral mobility, adverse events, and withdraws. The meta-analysis was performed using the Review Manager(®) 5.1 software by applying the random effects model. Eighteen studies were included in this review. No study of certolizumab was included. Patients treated with anti-TNF agents were more likely to display an ASAS 20 response after 12/14 weeks (RR 2.21; 95 % CI 1.91; 2.56) and 24 weeks (RR 2.68; 95 % CI 2.06; 3.48) compared with controls, which was also true for several other efficacy outcomes. Meta-analysis of safety outcomes and withdraws did not indicate statistically significant differences between treatment and control groups after 12 or 30 weeks. Adalimumab, infliximab, etanercept, and golimumab can effectively reduce the signs and symptoms of the axial component of ankylosing spondylitis. Safety outcomes deserve further study, especially with respect to long-term follow-ups.
- Validation of an Adapted Arabic Version of Fibromyalgia Syndrome Impact Questionnaire. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 17.
Fibromyalgia (FM) is the most common chronic pain syndrome encountered in medical practice, affecting females more than males, and the estimated prevalence of FM in Egypt is 1.3 %. The aim was to translate and adapt the Fibromyalgia Impact Questionnaire (FIQ) into Arabic and assess reliability and validity. The Arabic version of Fibromyalgia Impact Questionnaire (FIQ-A) was adapted following the forward/backward translation approach. Fifty-one female patients with FM were studied to assess psychometric properties of the FIQ-A. Reliability was analyzed by the correlation coefficient between test and retest. Internal consistency was checked by the Cronbach's alpha coefficient. Construct validity was assessed comparing FIQ-A with Health Assessment Questionnaire (HAQ), Health Assessment Questionnaire of Fibromyalgia (FHAQ), The Medical Outcome Survey Short-Form-36 (SF-36), and the Total Visual Analog Scale (TVAS) for FM symptom, and feasibility was assessed by the time taken in completing the FIQ-A and the proportion of patients completed the questionnaire. Patients studied were 33.2 ± 9.8 years old. Translation was concordant. Adaptation affected 4 sub-items of physical function. Test-retest correlation coefficient was 0.89 for total FIQ-A and Cronbach's alpha was 0.76. Excellent to good statistically significant correlations (p < 0.05) were found between the FIQ-A items and HAQ, FHAQ, and SF-36. The FIQ-A is a reliable, valid for measuring health status and physical function in Arabic-speaking FM patients.
- Evaluation of the mean platelet volume in secondary amyloidosis due to familial Mediterranean fever. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 15.
Familial Mediterranean fever (FMF) is an inflammatory disorder that is leading cause of secondary amyloidosis (AA). This study was designed to investigate the level of mean platelet volume (MPV) in AA. Seventy-four FMF, 29 AA patients and 180 healthy controls, were included. There was no significant difference between the cases in terms of sex and age. MPV levels were measured in all groups. In the FMF group, MPV level was significantly higher when compared to the control group. MPV level was significantly lower in AA group in comparison with the FMF and healthy control groups. In summary, our present study showed low MPV values in AA due to FMF.
- Serum macrophage migration inhibitory factor levels are correlated with response to tocilizumab therapy in patients with rheumatoid arthritis. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 14.
To examine the relationship between serum cytokine levels and response to tocilizumab in patients with RA. The disease status of 21 RA patients was assessed at baseline and after 12 weeks of tocilizumab treatment, using the clinical disease activity index (CDAI). Clinical response to tocilizumab was defined as an improvement of >50 % from the baseline CDAI. Serum cytokine levels were quantified using double-ligand ELISA for TNF-α, IL-6, CCL2, CCL3, CXCL8, CXCL10, CX3CL1, and macrophage migration inhibitory factor (MIF). After 12 weeks of tocilizumab treatment, there was a significant overall reduction in RA disease activity (CDAI), from 22.4 ± 11.3 to 9.2 ± 6.6 (p < 0.0001), across the entire patient group. After 12 weeks of tocilizumab treatment, 14 patients achieved a >50 % improvement (the responder group), but there were no significant responses in the other 7 patients (the non-responder group). The erythrocyte sedimentation rate levels, the positive % of anti-cyclic citrullinated protein antibody and patients (%) receiving methotrexate in combination with tocilizumab were significantly higher in the responder group than in the non-responder group. Although serum baseline levels of CCL2 and CXCL8 were higher in the responder group than in the non-responder group, there were no significant changes in these chemokine levels after treatment. The serum MIF levels, but not the levels of other cytokines, in the responder group were significantly decreased after tocilizumab treatment. Our results suggest that tocilizumab differentially regulates serum cytokine profiles in patients with RA, and MIF regulation in patients with active RA may be sensitive to anti-IL-6 therapy.
- Association between leptin and systemic lupus erythematosus. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 11.
Leptin, the product of ob gene, is a 16-kDa nonglycosylated peptide hormone produced by adipocytes that regulates appetite and energy expenditure at the hypothalamic level. As is known to be a satiety factor that can regulate body weight by inhibiting food intake and stimulating energy expenditure, leptin is a pleiotropic hormone whose multiple effects include regulation of endocrine function, reproduction and immunity. Since leptin has been considered to be a pro-inflammatory cytokine, investigations of leptin in the pathogenesis of autoimmune diseases have been detected, such as systemic lupus erythematosus, rheumatoid arthritis and osteoarthritis. Recently, the role of leptin in the modulation of immune response and inflammation has been discussed in the autoimmune diseases increasingly but less in systemic lupus erythematosus (SLE). Therefore, this article will focus on the current understanding of the role of leptin with such similar pathogenic mechanism in SLE in order to provide insights which may assist in the development of leptin-based approaches for the treatment of SLE.
- Evaluation of the association between Hispanic ethnicity and disease activity and severity in a large cohort of patients with juvenile idiopathic arthritis. [JOURNAL ARTICLE]
- Rheumatol Int 2013 May 10.
To examine the association between ethnicity and disease activity in patients with juvenile idiopathic arthritis (JIA), and to determine the association of ethnicity with disease severity and disability in this population. CARRAnet, a US database containing information (collected between May 2010 and June 2011) on almost 3,000 subjects with JIA, was used. Demographic variables were compared between Hispanic patients and non-Hispanic patients. Mann-Whitney and chi-square tests were used to compare indicators of disease activity, as well as imaging evidence of joint damage, and Childhood Health Assessment Questionnaire (CHAQ) scores between ethnicities. Two linear regression models were used to determine the association of ethnicity with number of active joints in JIA, and the association between ethnicity and disability (CHAQ scores). A total of 2,704 patients with JIA (277 Hispanic; 2,427 non-Hispanic) were included. Income and health insurance coverage were higher in non-Hispanics. RF-positive polyarticular JIA, positive RF and anti-CCP, as well as use of systemic steroids were more frequent in Hispanics. Imaging evidence of joint damage was present in 32 % of the Hispanic patients compared to 24 % of the non-Hispanic patients (p = 0.008). In multivariate linear regression analyses, the number of active joints was significantly higher in Hispanics than in non-Hispanics (p = 0.03), as well as CHAQ scores (p = 0.003), after adjusting for confounders. Hispanic patients with JIA had higher disease activity than non-Hispanic patients, as well as higher disease severity and disability. Since ethnicity influences disease activity, severity, and disability, different management and treatment plans should be planned accordingly.
