目的分析河北省秦皇岛地区成人肺炎支原体感染流行情况,为防治支原体感染提供科学依据。方法用颗粒凝集试剂盒检测2 426份临床疑似肺炎支原体感染者的血清抗体,判断肺炎支原体感染者并分析其流行病学资料。结果肺炎支原体抗体(MP-Ig M)总检出率为9.4%;女性阳性率11.8%(143/1 216),男性7.1%(86/1 210);春、夏、秋、冬4季阳性率分别为7.8%、5.8%、10.7%和12.0%;16~44岁、45~59岁、60岁以上患者的MP-Ig M阳性率分别为20.8%、7.6%、3.0%,以上性别、季节、年龄的差异均有统计学意义(P<0.01)。门诊为肺炎支原体抗体阳性率高的标本来源,门诊23.1%(82/355),病房7.1%(147/2 071)。结论河北省秦皇岛地区成人肺炎支原体抗体阳性率女性高于男性,冬季和青壮年分别是成人肺炎支原体感染的高峰季节和高峰年龄组,门诊为肺炎支原体抗体阳性率高的标本来源。
Objective To analyze the prevalence of mycoplasma pneumoniae infection in Qinhuangdao of Hebei Province and provide a scientific basis for the prevention and treatment of mycoplasma infection. Methods Two hundred and sixty-six serum samples from patients with suspected Mycoplasma pneumoniae infection were detected by particle agglutination kit. The prevalence of Mycoplasma pneumoniae was determined and the epidemiological data were analyzed. Results The total positive rate of Mycoplasma pneumoniae antibody (MP-Ig M) was 9.4%. The positive rate was 11.8% (143/1 216) in women and 7.1% (86/1 210) in males. The positive rates in spring, summer, autumn and winter were The positive rates of MP-Ig M in patients aged 16-44, 45-59 and 60 years old were 20.8%, 7.6% and 3.0%, respectively. The positive rates of MP-Ig M in patients aged above 60 years old were 7.8%, 5.8%, 10.7% and 12.0% The differences of seasons and ages were statistically significant (P <0.01). Outpatient samples of mycoplasma pneumoniae antibody positive rate of source, outpatient 23.1% (82/355), ward 7.1% (147/2 071). Conclusions The positive rate of Mycoplasma pneumoniae antibodies in Qinhuangdao of Hebei Province is higher than that in males. The peak season and the peak age group of adult patients with Mycoplasma pneumoniae infection in winter and young adults respectively. The out-patient was the source of specimens with high positive rate of Mycoplasma pneumoniae.
