Research Abstract

【研究の背景と方法】
Epstein-Barrウイルス(EBV)によるBリンパ球増殖症は、肝臓移植術後1ヶ月後以降好発し、5-10%のレシピエントにみられる、日和見感染症である。頻度的にはウイルス感染症として、サイトメガロウイルスについで二番目であるが、重篤化すると致死率が高いことと、特異的治療法が一般的にないことから、移植患者にとってもっとも警戒すべき感染症の一つである。発熱、咽頭痛、リンパ節腫大、肝脾腫などの臨床症状およびEBVのvirus capsid antigen値および末梢血リンパ球のEBV encoded small nuclear RNA (EBER)のin situハイブリダイゼーション(ISH)の所見にてEBV感染症の診断を24例の小児患者に行った。まず従来のEBER ISHとキットを使用した方法(ニチレイ(株))、ついでファルマ社のマイクロプローブ染色装置を用いて、レシピエント末梢血リンパ球を検体として、EBER ISHを施行し、結果と所要時間を比較検討する。
【研究結果】
所要時間は従来法で平均23時間、マイクロプローブ染色法で5.8時間であった。マイクロプローブ染色法においては、特定の条件設定は必要なかった。陽性症例は両方法において一致していた。
