Abstract

Background Acarbose was found to decrease inflammatory parameters in diabetic mellitus (DM) patients. However, whether acarbose reduces the risk of rheumatoid arthritis (RA) and collagen-induced arthritis (CIA) with immunomodulatory effects has not been established.

Objectives To examine the influence of acarbose on RA risk in DM patients and on the incidence and severity of CIA in mice.

Methods In a nationwide, matched case–control study, we identified 723 incident RA cases and selected 7,230 age-, sex- and RA diagnosis date–matched controls from all newly treated DM patients. The effect of acarbose was tested by conditional logistic regression analyses adjusting for potential confounders. In a CIA mouse study, acarbose was orally administered from day -7 to 38 after type II collagen (CII) immunization and arthritis activity was evaluated by arthritic score and the joint histopathology. Levels of cytokines and anti-CII antibodies were detected by ELISA. The expansion of CII-specific lymphocytes in the lymph nodes were determined by [3H] thymidine incorporation assay.

Results Use of acarbose >16950 mg per year was associated with a lower RA risk (odds ratio [OR] 0.60; 95% CI, 0.41–0.89). Acarbose at a dose of 500 mg/kg/day attenuated arthritis incidence, severity and proinflammatory cytokines expressions including TNF-α, IL-6 and IL-17A in paw tissues of CIA mice. Acarbose further decreased the production of anti-CII-IgG, and IL-17A and IFN-g by collagen-reactive lymph node cells in CIA mice. However, the expression of IL-10 was significantly increased in acarbose-treated mice compared with the control mice.

Conclusions The use of acarbose decreased the risk of RA in DM patients and the incidence of CIA in mice. Acarbose also attenuated the severity of CIA with anti-inflammatory and immunomodulatory effects.
