要約 目的:Vogt-小柳-原田病(VKH)症例について病型別の臨床所見の検討を行った。
対象と方法:2007年1月1日〜2020年12月31日に福岡大学病院で初発VKHと診断され入院治療を行った37症例を乳頭炎型と剝離型に分け,入院時年齢,初診時視力,入院期間,体重当たりプレドニゾロン(PSL)換算ステロイド総投与量,ステロイド全身投与期間,ステロイド30mgに減量するまでの期間,最終視力,再発の有無について検討した。
結果:全症例は37例で,平均年齢(±標準偏差)は50.9±17.4歳(12〜82歳),男性13例,女性24例で,女性に多かった。乳頭炎型10例,剝離型27例で,それぞれの平均年齢は60.5歳と47.4歳であり,有意に乳頭炎型で高かった。再発は全体の9例(24.3%)であり,乳頭炎型の3例(33%),剝離型の6例(22%)で再発した。病型別再発率は剝離型で22%,乳頭炎型で30%であった。初診時視力,入院期間,体重当たりPSL換算ステロイド総投与量,ステロイド全身投与期間,ステロイド30mgに減量するまでの期間,最終視力については両群に有意差はなかった。
結論:乳頭炎型は発症年齢が高く,剝離型に比べ再発も多い傾向にあり注意が必要である。VKHに対するステロイド全身投与は,年齢や病型ごとに考慮すべきことが示唆された。
Abstract Purpose:To describe the clinical features of patients with Vogt-Koyanagi-Harada disease(VKH)from the standpoint of clinical types.
Methods:Thirty seven patients initially diagnosed with VKH and treated at Fukuoka University Hospital between 2007 and 2020 were divided into cases of papillitis or serous retinal detachment types. The two groups were statistically evaluated for the following items:Age at admission, initial visual acuity, hospitalization period, total dose of prednisolone per body weight-equivalent steroids administered, duration of steroid administration, the period until the systemic dose of corticosteroids is reduced to 30 mg per day final visual acuity, and the presence of recurrence.
Results:Of the 37 patients(13 men, 24 women), 10 cases of papillitis type and 27 cases of serous retinal detachment type were observed, respectively. The mean(±standard deviation)age of the groups was 60.5±12.3 years and 47.4±17.8 years, respectively, and a significantly higher mean age was observed in patients with papillitis type than those with serous retinal detachment type. Recurrence rate was 24.3% in all patients, including 33% in the papillitis type and 22% in the serous retinal detachment type.
Conclusions:Papillitis type tended to have a higher age of onset and more recurrences than serous retinal detachment type, and careful attention is required toward this finding. Systemic administration of steroids for VKH should be considered according to age and type of disease.
