A new study adds to the evidence that metabolic factors play an important role in the pathogenesis of rheumatoid arthritis (RA). In this large, prospective cohort study, Liu et al. found that increased physical activity among women was associated with a reduced risk of RA…
New research has examined the effect of obesity on inflammatory markers, specifically C-reactive protein (CRP) level and erythrocyte sedimentation rate, in patients with rheumatoid arthritis (RA). Researchers found higher BMIs were associated with higher CRP levels in women both with and without RA, suggesting the phenomenon is related to adiposity and not an indication of disease activity. For men with RA, low BMI was associated with higher CRP levels, which proved to be RA-specific but not a direct causal effect of adiposity…
Research from Gloersen et al. suggests the systemic effects of obesity, as measured by leptin, may play a role in the severity of pain experienced by patients with hand osteoarthritis.
Obesity has an established systemic inflammatory component. Could that be a trigger for the inflammation seen in rheumatoid arthritis (RA) and other rheumatic diseases? Although there is no direct scientific evidence, both mechanistic and epidemiologic clues do give some intriguing suggestions of a possible link. “At first, we thought that fat was involved only in…
