The indirect fluorescent-antibody technique was compared with indirect and mu-capture enzyme-linked immunosorbent assays for the detection of respiratory syncytial virus (RSV) immunoglobulin M (IgM) in the elderly. Sera from 47 patients (mean age, 70 years) with acute lower respiratory tract infections caused by RSV were investigated. Specific IgM was detected in 81% (38 of 47) of the patients. The fluorescent-antibody technique, which gave 70% positive results, proved to be the most sensitive of the three methods. An IgM response was seldom seen in sera from the elderly within the first week of disease, but was present in 85% of sera (33 of 39) collected between days 11 and 30 of disease. In some patients it persisted for more than 6 weeks. Detection of IgM was found to be a useful tool for the diagnosis of RSV infections in elderly patients.
为检测老年人呼吸道合胞病毒(RSV)免疫球蛋白M(IgM),对间接荧光抗体技术与间接和μ捕获酶联免疫吸附试验进行了比较。研究了47例(平均年龄70岁)由RSV引起的急性下呼吸道感染患者的血清。在81%(47例中的38例)的患者中检测到特异性IgM。荧光抗体技术的阳性结果为70%,被证明是三种方法中最敏感的。在疾病的第一周内,老年人血清中很少出现IgM反应,但在疾病第11天至30天之间采集的血清中,85%(39例中的33例)出现了IgM反应。在一些患者中,IgM反应持续超过6周。发现检测IgM是诊断老年患者RSV感染的有用工具。
