目的:对小儿反复呼吸道感染(RRTI)的影响因素进行探究。方法:选择23例正常健康儿童为对照组,23例RRTI患儿为病例组,分别对可能导致他们免疫功能缺陷的16项因素作检测分析。结果:免疫抑制剂的错误使用、缺铁性贫血以及维生素等微量元素缺乏都可能是小儿RRTI的发病原因。结论:有效防治营养性疾病、指导合理喂养以及逐渐加强对儿童的保健能在一定程度上减少RRTI发病因素。
Objective: To investigate the influential factors of recurrent respiratory tract infection (RRTI) in children. Methods: Twenty-three healthy children were selected as the control group. Twenty-three RRTI children were selected as the case group. Sixteen factors that may cause their immune dysfunction were detected and analyzed. RESULTS: Incorrect use of immunosuppressive agents, iron deficiency anemia, and lack of trace elements such as vitamins may be responsible for the pathogenesis of RRTI in children. Conclusion: The effective prevention and treatment of nutritional diseases, to guide the rational feeding and gradually strengthen the health care of children can reduce the incidence of RRTI to some extent.
