鸟分枝杆菌复合体(MAC)生物体在AIDS患者中引起播散性疾病。微生物通过未知机制穿透胃肠道粘膜,并被固有层中的巨噬细胞吞噬。这些细胞不能杀死微生物,MAC通过粘膜下组织传播。淋巴引流将分枝杆菌运送到腹部淋巴结,生物体从那里进入血液。血行播散可发生在许多部位,但脾、骨髓和肝是最常见的。组织破坏是罕见的,MAC疾病的大多数体征和症状是由于细胞因子的产生。MAC很少是死亡的直接原因,但会增加重复感染的风险;死亡可能由营养不良或其他感染引起。
Mycobacterium avium complex (MAC) organisms cause disseminated disease in patients with AIDS. The organisms penetrate the gastrointestinal mucosa by unknown mechanisms and are phagocytosed by macrophages in the lamina propria. These cells cannot kill the organisms, and MAC spreads through the submucosal tissue. Lymphatic drainage transports mycobacteria to abdominal lymph nodes, from which the organisms enter the bloodstream. Hematogenous spread can occur to many sites, but spleen, bone marrow, and liver are the most common. Tissue destruction is rare, and most signs and symptoms of MAC disease are due to elaboration of cytokines. MAC is rarely the direct cause of death but increases the risk for superinfection; death may result from malnutrition or other infections.
