Predictive factors and adalimumab efficacy in managing chronic recurrence Vogt-Koyanagi-Harada disease.

ABSTRACT

BACKGROUND: This study explores prognostic factors influencing Vogt-Koyanagi-Harada (VKH) disease and observes the efficacy and safety of Adalimumab (ADA) in treating recurrence in Vogt-Koyanagi-Harada (VKH) patients. METHODS: A retrospective study was conducted on all patients diagnosed with VKH disease at Beijing Tongren Hospital between 2020 and 2023. Clinical data included initial and final visual acuity, age, gender, ocular complications, treatment modalities, disease duration, and recurrence frequency. RESULTS: A total of 62 VKH patients were included, comprising 34 in the acute-resolved group and 28 in the chronic-recurrent group. The mean age of patients in the acute-resolved group was 38.29 ± 15.46 years, while the mean age of chronic-recurrent group had a 49.00 ± 16.43 years. Initial best-corrected visual acuity (BCVA) examination at the first visit showed an average BCVA of 0.64 ± 0.29 logMAR in the acute-resolved group and 1.38 ± 0.54 logMAR in the chronic-recurrent group (p = 0.002). During follow-up, ocular complications were observed in 29.4% of the acute-resolved group patients and 41.7% of the chronic-recurrent group patients (P = 0.006). "Sunset glow fundus" was observed in 23.5% of the acute-resolved group and 64.3% of the chronic-recurrent group patients (P = 0.001). Poor initial BCVA (P = 0.046) and the occurrence of "sunset glow fundus" (P = 0.040) were significantly associated with progression to the chronic recurrent phase. Logistic regression analysis revealed that older age at onset (P = 0.042) and the occurrence of "sunset glow fundus" (P = 0.037) were significant predictors for progression to the chronic recurrent phase. ADA significantly reduced anterior chamber inflammatory cells (P = 0.000) and vitreous cavity inflammatory cells (P = 0.001) in the chronic-recurrent group, and markedly decreased the recurrence rate in VKH patients (P = 0.009). CONCLUSION: In comparison to acute-resolved patients, chronic-recurrent patients exhibited poorer initial BCVA and a significantly increased incidence of "sunset glow fundus." Older age at onset and the occurrence of "sunset glow fundus" at diagnosis are crucial predictive factors for VKH patients progressing to the chronic recurrent phase. ADA effectively alleviates refractory VKH disease and is generally well-tolerated.
