Contributions of a group-based exercise program for coping with fibromyalgia: a qualitative study giving voice to female patients.

Numerous quantitative studies have illustrated the potential usefulness of exercise programs for women with fibromyalgia. However, a deeper understanding of the physical and especially psychosocial benefits of exercise therapy from the subjective perspective of this population is still needed. This study was conducted with 25 women who had fibromyalgia and were participating in a nine-month, group-based exercise program. The aim was to provide an in-depth description and analysis of the perceived physical and psychosocial benefits of participation. Qualitative data were collected through observation, interviews, and focus groups. The exercise program not only alleviated the physical symptoms of fibromyalgia, but social interactions within the group helped to counteract the isolation, frustration, and depression often associated with this chronic condition. The data from this study may contribute to a deeper understanding of the benefits of exercise for women with fibromyalgia and might be useful for the improvement of future exercise programs for this population.

Interferon regulatory factor 5 gene polymorphism confers risk to several rheumatic diseases and correlates with expression of alternative thymic transcripts.

OBJECTIVES: Polymorphisms in genes related to the IFN pathway were investigated for susceptibility to rheumatic diseases and correlation with gene expression in thymus. METHODS: Forty-five polymorphisms were genotyped in Norwegian patients with RA (n = 518), JIA (n = 440), SLE (n = 154) and healthy controls (n = 756). Forty-two thymic samples were used for gene expression analysis. Six hundred and fifty SLE patients and 737 healthy controls from Spain were available for replication. RESULTS: We found a novel association between interferon regulatory factor 5 (IRF5), rs2004640 and JIA, in particular with the polyarthritis RF-negative patients [odds ratio (OR) = 1.60; 95% confidence interval (CI) 1.17, 2.20; P = 0.003]. Also, we confirmed the associations between rs2004640 and SLE (OR = 1.95; 95% CI 1.50, 2.53; P = 3.75 × 10(-7)), which was further strengthened in a meta-analysis (OR = 1.44; 95% CI 1.36, 1.52; P = 2.11 × 10(-37)). Suggestive evidence of association between rs2004640 and RA was found in the Norwegian discovery cohort (OR = 1.19; 95% CI 1.02, 1.40; P = 0.029) and strengthened in a meta-analysis (OR = 1.11; 95% CI 1.05, 1.18; P = 0.00028). Expression levels of exon 1B IRF5 transcripts were dependent on the presence of the rs2004640 T risk allele in thymic tissue, while exon 1A transcript levels correlated with IRF5 promoter CGGGG-indel variants. CONCLUSION: The IFN pathway gene, IRF5, is a common susceptibility factor for several rheumatic and autoimmune diseases, and risk variants are correlated with expression of alternative IRF5 transcripts in thymus implying a regulatory role.
