Effects of oral alpha-lipoic acid supplement on some blood biochemical parameters and clinical status in women with rheumatoid arthritis.

Protocol summary

Summary
In this double blind randomized controlled trial the effects of alpha-lipoic acid supplement on some biochemical markers and clinical status in rheumatoid arthritis patients will be evaluated. Women with RA who are at 20-50 years of age and meet the inclusion criteria will be recruited from clinics of Tabriz University of Medical Sciences. After describing the research, if patients want to attend in our study, an informed written consent will be taken. Eventually, 70 patients will be entered the study and they will be allocated randomly into intervention or placebo group to receive alpha-lipoic acid or maltodextrin (each group receives 2 capsules a day for 8 weeks and each capsule contains 600 mg alpha-lipoic acid or maltodextrin). At the beginning of the study an interviewer fill in a demographic questionnaire (including information about age, job, disease history, etc). Before and after the intervention, anthropometric measurements (BMI, waist and hip circumferences) and disease activity score-28 will be evaluated. At baseline and final, fasting blood samples will be gathered to test hsCRP, TNFa,IL-6, RF ,MMP-3, ICAM-1, VCAM-1, lipid profile (TC, TG, HDL -C and LDL-C), TAC, MDA and arylesterase activity in serum as well as SOD and GSH-Px activities in whole blood. Also, 3-day dietary records, physical activity level and anxiety status will be assessed by special questionnaires before and after the study. Finally, biochemical, clinical, anthropometric and dietary data will be statistically analyzed
