To identify triggering factors for the next inflammatory episode of recurrent acute anterior uveitis (RAAU), a 1:1 case–control study was conducted. We interviewed RAAU patients with recent acute anterior uveitis attack and quiescent controls for their information during a previous month using Srithanya Stress Test (ST-5) and questionnaires about potential triggering factors. Asymptomatic controls were matched for age (± 5 years), sex, and HLA-B27. There were 39 pairs of cases and controls. Patients who recently experienced a uveitis attack demonstrated higher mean ST-5 scores (3.7 ± 2.9 vs 0.7 ± 1.1) and shorter sleep time (6.3 ± 1.4 vs 7.4 ± 0.7 h per day) compared with their controls. In the multivariate conditional logistic regression analysis, ST-5 score ≥ 3 (OR 9.07, 95% CI 1.14–72.16, p = 0.037) and sleep time < 7 h per day (OR 12.12, 95% CI 1.37–107.17, p = 0.025) were more likely to trigger a uveitis attack in RAAU accounted for patients’ age, sex, HLA- B27 positivity, and presence of concurrent anti-inflammatory drugs for co-existing diseases. Other suspected triggering factors were not found to have any significant association. In short, stress and inadequate sleep may lead to the future episode of acute anterior uveitis in RAAU. Both physical and emotional stress management should be advised to RAAU patients to minimize recurrences and further complications.

Asymptomatic controls were matched for age (±5 years), sex, and HLA-B27. There were 39 pairs of cases and controls. Within 1-month before the interview, patients who recently experienced a uveitis attack demonstrated higher mean ST-5 scores (3.7±2.9 vs 0.7±1.1) and shorter sleep time (6.3±1.4 vs 7.4±0.7) compared with their controls. In the multivariate conditional logistic regression analysis, ST-5 score ≥3 (OR 9.17; 95%CI 1.15-72.84, p=0.036) and sleep time <7 hours per day (OR 11.57; 95% CI 1.42-94.55, p=0.022) were more likely to trigger a uveitis attack in RAAU accounted for age, sex, and HLA-B27 positivity of the patients. Other suspected triggering factors were not found to have any significant association. In short, emotional stress and inadequate sleep are the major triggering factors that lead to the future episode of acute anterior uveitis in RAAU. Both physical and emotional stress management may be helpful to minimize recurrences and further complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
