The Effect of Low-dose Cyclosporine (100 mg Once Daily) for Chronic Vogt-Koyanagi-Harada Disease.

Abstract

Purpose: To determine the effect of low-dose cyclosporine (CyA) treatment for patients with chronic Vogt-Koyanagi-Harada (VKH) disease resistance to systemic corticosteroid treatment. Methods: We retrospectively evaluated patients diagnosed with chronic VKH disease resistance to systemic corticosteroid treatment at Japan Community Health Care Organization (JCHO) Osaka Hospital between March 2013 and March 2016. We followed the observation with systemic low-dose CyA (100 mg once daily) treatment of these patients. The patients were divided into two groups, anterior ocular inflammation group and posterior ocular inflammation group. Demographic data were reviewed, including age, gender, the existence of inflammation at the initial visit and three months after CyA treatment, and side effect. Results: Twenty-three eyes of thirteen patients with chronic VKH disease were included in this study (11 women, 2 men; mean age, 54.6±11.9 years). Nine cases showed anterior ocular inflammation and seven cases showed posterior ocular inflammation (includes overlapping cases). Thirteen of fourteen eyes in the anterior ocular inflammation group subsided at three months after CyA treatment, and ten of thirteen eyes in the posterior ocular inflammation group subsided at three months after treatment. We had to stop the treatment in one patient because of severe increase of serum triglyceride. Conclusions: Low-dose CyA treatment was effective in patients with chronic VKH resistance to systemic corticosteroid treatment. Our results suggest that this treatment was more effective in the anterior ocular inflammation group than in the posterior ocular inflammation group; however, a larger number of patients and longer observation periods are needed to confirm these results.
