目的　探讨儿童哮喘对肾功能的损伤。方法　用RIA法测定 2 1例正常儿童 ,5 4例哮喘急性发作期及 2 4例缓解期患儿尿 β2 MG ,Alb及IgG含量。结果　急性期哮喘儿尿微量蛋白明显高于正常对照组 ,重度发作组升高尤著 ,缓解期降至正常。结论　哮喘急性发作可引起可逆性肾损伤。 Objective To investigate the effects of childhood asthma on renal function. Methods The urinary β2 MG, Alb and IgG levels in 21 normal children, 54 acute exacerbations and 24 children with remission were measured by RIA method. Results In the acute phase, the urinary microalbuminuria in asthmatic children was significantly higher than that in the normal control group, especially in the severe seizure group and normal in the remission period. Conclusion The acute attack of asthma can cause reversible renal injury.
