Older person with rheumatoid arthritis (RA) make up an increasing proportion of those treated with biologic disease modifying anti-rheumatic agents (DMARDs). The safety of these agents may differ for this subgroup of older RA patients, yet effects have generally not been selectively studied in this population.
A strong association between chondrocalcinosis, resulting from calcium pyrophosphate dihydrate (CPPD) deposition, and knee osteoarthritis (OA) is firmly established. However, despite the association, a causative pathogenic role for CPPD crystals on the progression of articular degeneration in the knee has not been definitively demonstrated.
Although compelling, no clear-cut links between dietary factors and the risk of developing rheumatoid arthritis (RA) have been confirmed. Recent investigations have implicated increased consumption of red meat as a risk factor for incident inflammatory arthritis.
The molecular mechanisms leading to erosive joint damage in some, but not all, patients with rheumatoid arthritis (RA) are incompletely understood. Downstream effects of inflammatory cytokines produced by rheumatoid synovium include the induction of RANKL, a powerful osteoclast activator, the action of which is physiologically opposed by its naturally occurring antagonist osteoprotegerin (OPG).
Changes in disease activity during pregnancy and the peri-partum period have long been recognized features of systemic autoimmune disease. Moreover, as certain autoimmune diseases, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), frequently affect women of childbearing age, there is the potential for the disease to affect pregnancy outcomes. However, despite the frequency […]
