慢性腹泻是某些原发免疫缺陷病人的主要并发症,免疫缺陷病人易因一般和毒力较低的病毒引起慢性致死性感染。本文研究轮状病毒(RV)在免疫缺陷儿腹泻中的作用及其在免疫缺陷儿和正常儿间感染的临床过程是否有差异。研究组共有23例原发缺陷性疾病的患儿,年龄为4个月～18岁。对照组包括46例因急性胃肠炎住院,年 Chronic diarrhea is a major complication in some patients with primary immunodeficiency. Patients with immunodeficiency are at risk for chronic, lethal infections due to lower rates of general and virulent viruses. This article studies the role of rotavirus (RV) in diarrhea in immunocompromised children and whether there is any difference in the clinical course of infection between immunocompromised and normal children. Study group, a total of 23 cases of primary defects of children, aged 4 months to 18 years. The control group included 46 cases hospitalized for acute gastroenteritis, year
