Abstract

Serum and nasopharyngeal IgA antibody levels were estimated in 20 malnourished children and 20 matched healthy controls after immunization with a single dose of live attenuated measles or poliovirus vaccine. Seroconversion and serum neutralizing antibody titres were comparable in the two groups. Secretory IgA antibody was detected significantly less often in undernourished children; the time of its first appearance was delayed-and its maximum level was significantly lower. Impaired secretory antibody response in malnourished children may contribute to slow inadequate recovery from viral and enterobacterial infections and predispose to lifethreatening complications.

摘要

在20名营养不良儿童和20名匹配的健康对照儿童中,给予单剂量减毒活麻疹或脊髓灰质炎疫苗免疫后,测定血清和鼻咽部IgA抗体水平。两组的血清转化和血清中和抗体滴度相当。营养不良儿童中分泌型IgA抗体的检测频率明显较低;其首次出现的时间延迟,且最高水平显著降低。营养不良儿童分泌性抗体反应受损可能导致从病毒和肠道细菌感染中恢复缓慢且不完全,并易引发危及生命的并发症。
