ABSTRACT
OBJECTIVE:
Uveitis is a common manifestation of various autoimmune diseases and can lead to severe visual impairment. Hydroxychloroquine (HCQ) is an antimalarial drug that is also used to treat autoimmune diseases. The aim of this study was to investigate the association between HCQ use and the incidence of uveitis in patients with autoimmune diseases, as well as to identify potential risk factors for the development of uveitis in this study.METHODS:
We conducted a population-based cohort study using a nationwide database to investigate the incidence of uveitis in patients with autoimmune diseases who received HCQ treatment. We selected non-HCQ comparison cohort at a 11 ratio by propensity score matching on age, sex, index date, urbanization, income, comorbidities, and medications. The data were analyzed using Cox proportional hazards models, and propensity score matching (PSM) was used to reduce selection bias.RESULTS:
Our study included 15 822 patients with autoimmune diseases. After 11 PSM, there were 4555 individuals in both the HCQ group (n = 4555) and the non-HCQ group (n = 4555). The multiple Cox proportional hazard regression analysis was used for the estimation of adjusted hazard ratios on uveitis. After PSM, the adjusted hazard ratio for the HCQ group was 0.74 (95% CI = 0.58-0.95). These findings suggest that HCQ may play a protective role in reducing the risk of uveitis in patients with autoimmune diseases, including rheumatoid arthritis, Sjogren's syndrome, and systemic lupus erythematosus groups. The Kaplan-Meier survival curves also showed a significantly lower incidence of uveitis in the HCQ group (log-rank = 0.0229) after PSM.CONCLUSION:
HCQ use is associated with a lower incidence of uveitis in patients with autoimmune diseases. Further studies are needed to confirm this association and to investigate the underlying mechanisms.Key words
