ABSTRACT
INTRODUCTION: Rheumatoid arthritis (RA) is one of the most prevalent autoimmune diseases worldwide. Some researchers have suggested that the serum vitamin D (Vit D) level may relate to disease activity. The current study was designed to identify the correlation between vitamin D prescription and prevention of relapses in rheumatoid arthritis. PATIENTS AND METHOD: A double blinded, randomized controlled trial study was performed using 80 RA patients. RA was controlled and patients were in remission during the past 2 months. Serum level of Vit D in the studied patients was below 30 ng/dl. Patients were randomly allocated to receive Vit D or placebo. In the 6-month follow-up period, the Disease Activity Score 28 (DAS28) was used in case of relapses as an index of RA activity to compare the two groups. RESULTS: The flare rate was not different between two groups (p > 0.05). The odds ratio of the rate of decline in patients of the trial group compared with the control group was 1.17 (not significant; p > 0.05). The mean DAS28 between the two patient groups was not significant (p > 0.05). CONCLUSION: A low Vit D level was not identified to be a risk factor for RA severity or flare ups; however, although not statistically significant, Vit D treatment might be clinically effective. Further studies are needed with more emphasis on the issue of cost effectiveness and clinical importance to provide more information.

INTRODUCTION: Frozen shoulder or adhesive capsulitis is a relatively common encountered musculo-skeletal disease in which arouses following soft tissue involvement of glenohumeral joint and presents with pain and limitation of shoulder' active and passive motions. The incidence of frozen shoulder among diabetic patients is about 10-20%, stiffness in such patients is more severe and should be managed actively. Local Glucocorticoid injection, NSAIDs and physiotherapy each can relief the symptoms. The aim of this study was to compare the efficacy of glenohumeral injection of Glucocorticoid with NSAIDs in frozen shoulder of diabetic patients. METHOD: The randomized clinical trial study conducted during Feb 2009-Aug 2010 on diabetic patients with frozen shoulder that were referred to rheumatology and endocrinology clinics, Yazd, Iran. Diagnostic criteria of capsulitis were pain of shoulder and range of motion limitation in all directions. The patients were divided into 2 groups, patients of first group received NSAID while the latter group were undergone intra-articular corticosteroid injection. After 1 week, home exercise was done for both group and evaluation of the patients after first visit was done likewise 2nd, 6th, 12th and 24th weeks. All registered data were transformed into SPSS-15 software and analyzed. RESULTS: Totally 57 patients (19 males (33.3%) and 38 females (66.7%) were included in the analysis. There was no significant difference between sex (P=0.4) and age (P=0.19) of patients. No significant relation was detected between 2 groups after 24 weeks according to range of motion in flexion (P=0.51), abduction (P=0.76), external rotation (0.12) and internal rotation (P=0.91). Also any significant difference in pain score was not detected (P=0.91). CONCLUSION: Based on our study, both intra-articular corticosteroid and NSAID are effective in treatment of adhesive capsulitis and there is no significant difference between efficacies of these 2 treatment modalities in diabetic patients.
