title: Effects of the duration of initial oral corticosteroid treatment on the recurrence of inflammation in Vogt-Koyanagi-Harada disease.
abstract: OBJECTIVE
  To evaluate the effects of the duration of oral corticosteroid treatment on the recurrence of inflammation in Vogt-Koyanagi-Harada (VKH) disease.
  
  
  METHODS
  Retrospective analysis of 35 VKH patients who received oral corticosteroid during the first attack of VKH with a minimum follow-up of 6 months. Patients were divided into two groups on the basis of the oral corticosteroid treatment duration of less than 6 months or 6 months or more. Kaplan-Meier survival and Cox-regression analyses were carried out to compare the recurrence rates of inflammation in the two groups.
  
  
  RESULTS
  The mean age of onset was 42.5 years and the mean follow-up duration was 3.6 years. During the follow-up period, 10 (58.8%) of the 17 patients who received oral corticosteroid for less than 6 months compared with 2 (11.1%) of the 18 patients who had treatment for 6 months or more developed recurrence of inflammation (P=0.003). Cox-regression analysis showed that the duration of oral corticosteroid treatment for less than 6 months was the only significant risk factor for recurrence of VKH after adjustment for age, gender, and the initial dosage of oral corticosteroid treatment (adjusted odds ratio=8.8, P=0.008). Patients who received oral corticosteroid treatment for less than 6 months were also more likely to have one eye with visual acuity of 20/200 or worse (P=0.016).
  
  
  CONCLUSIONS
  Early withdrawal of oral corticosteroid is associated with increased risk of recurrence of VKH and worse visual prognosis. Oral corticosteroid should be tapered off slowly and maintained for at least 6 months for the treatment of acute VKH.
