获得性免疫缺陷综合征(AIDS)是一种由人类 T 细胞白血病Ⅲ型病毒(HTLV-Ⅲ)引起的以继发性严重免疫缺陷为特征的传染病。胃肠道为 AIDS 时许多机会性感染的靶器官,因此胃肠道感染是 AIDS 及 AIDS相关复合症(ARC)常见的临床表现且为致死的重要原因。晚近有人甚至认为胃肠道感染可能作为一种辅助因素参与 AIDS 的发病过程。本文综述 AIDS 时常见的胃肠道感染,并对其与 AIDS 发病机理之间的关系加以简要讨论。一、胃肠道感染的常见表现(一)白色念珠菌感染:AIDS 患者出现口腔及食管念珠菌感染非常多见,且常同时合并巨细胞病毒等感染。临床表现为
Acquired immunodeficiency syndrome (AIDS) is an infectious disease characterized by secondary severe immunodeficiency caused by human T-cell leukemia type III virus (HTLV-III). Gastrointestinal tract is a target organ of many opportunistic infections when AIDS is caused. Therefore, gastrointestinal tract infection is a common clinical manifestation of AIDS and AIDS-related complex (ARC) and is an important cause of lethality. Recently, some people even think that gastrointestinal infections may participate as a cofactor in the pathogenesis of AIDS. This article reviews the common gastrointestinal infections in AIDS and briefly discusses their relationship with the pathogenesis of AIDS. First, the common manifestations of gastrointestinal infections (A) Candida albicans infection: AIDS patients with oral and esophageal candidiasis is very common, and often combined with cytomegalovirus and other infections. Clinical manifestations of
