要旨 Crohn病(以下,CD)に合併したアミロイドーシス(以下,AMY)は,CD 230例中11例で4.8%であった.CD発症後のAMY累積合併率は,5年で0.96%,10年で1.61%,20年で5.23%,25年で14.5%であった.合併率は,CD発症が20歳未満の症例,広範囲の小腸病変を有する症例が有意に高かった.アミロイドの生検陽性率は,胃・十二指腸は100%,直腸は70%であった.尿蛋白はAMY診断前にみられることが多く,平均3.0年で人工血液透析が開始となった.4例はAMY診断から0.2~3.7年で死亡された.AMYの画像の特徴は,アミロイド沈着を反映して,胃角部のひび割れたような粘膜,微細顆粒状隆起の多発からなる粗糙な粘膜であり,面の要素を持つ,びまん性の病変であった.
The incidence of AMY(amyloidosis)associated with CD(Crohn's disease)was 4.8%(11 of 230 cases). The 5-, 10-, 20-, and 25-year cumulative AMY complication rates after CD development were 0.96, 1.61, 5.23, and 14.5%, respectively. The complication rate was significantly higher in patients with a CD onset age younger than 20 years and those with extensive small intestinal lesions. The amyloid positive rate on biopsy was 100%in the stomach/duodenum and 70% in the rectum. Urinary protein was frequently detected before AMY was diagnosed, and hemodialysis was initiated after 3.0 years on average. Four patients died 0.2-3.7 years after the diagnosis of AMY. Imaging of amyloid deposition revealed a crack-like appearance of the gastric angle mucosa, rough mucosa due to many fine granule-like protrusions, and diffuse lesions with surface elements.
