Rome, Italy, Wednesday 16 June 2010: Alcohol consumption is associated with a significantly reduced risk of developing several arthritic conditions including Rheumatoid Arthritis (RA), Osteoarthritis (OA), reactive arthritis, psoriatic arthritis and spondylarthropathy, according to results of a new study presented today at EULAR 2010, the Annual Congress of the European League Against Rheumatism in Rome, Italy. Regardless of the type of arthritis, all patients reported drinking less alcohol than controls, leading to questions around the inflammatory pathways behind the effects seen.
In this Dutch study, alcohol consumption was associated with a significantly lower risk of developing RA (Odds Ratio (OR) 0.27 (0.22-0.34), Osteoarthritis (OR 0.31, (0.16-0.62), spondylarthropathy (OR 0.34, 0.17-0.67), psoriatic arthritis (OR 0.38, 0.23-0.62), and reactive arthritis (OR 0.27, 0.14-0.52). A particularly protective effect was shown in the RA population with the presence of Anti-Citrullinated Protein Antibodies (ACPA, potentially important surrogate markers for diagnosis and prognosis in RA), (OR 0.59, 0.30-0.99).
Interestingly, researchers also found that the degree of systemic inflammation in patients was shown to increase as the amount of alcohol consumed decreased (p=0.001) and that there was no dose response relationship (low 0.12 (0.08-0.18), moderate 0.46 (0.36-0.59), high 0.17 (0.12-0.25)) between the amount of alcohol consumed and the risk of arthritis development. Researchers hypothesise that there could be two explanations for this inflammatory effect; either that patients with more severe disease activity consume less alcohol due to associated changes in their lifestyle, or that the presence of alcohol in the system could protect against the development of systemic inflammation.
"We know from previous research that alcohol consumption may confer a protective effect against developing RA, our data have shown that this effect may apply to oth
