Analysis of Mycoplasma pneumoniae IgM antibody measurements in patients with Mycoplasma pneumoniae in Nanning

目的分析南宁市2013年肺炎支原体(MP)抗体检测结果,了解其感染状况及病原流行病学特点。方法采用被动明胶颗粒凝集法检测9 115例拟诊断为呼吸道感染患者血清MP抗体。结果 9 115例呼吸道患者检出MP阳性例数为4 558例,检出阳性率为50.00%,其中男性检出阳性率为46.75%,女性检出阳性率为54.13%,女性检出率高于男性,差异有统计学意义(P<0.05);不同年龄组中检出率最高为4岁^(60.60%)及8岁^(69.89%),≤1岁及>60岁以上患者阳性检出率最低分别为28.00%、28.26%,不同年龄组间差异有统计学意义(P<0.05);全年每月均可发病,冬季检出率最高,不同季节间差异有统计学意义(P<0.05)。结论南宁市2013年MP感染在性别、年龄、季节存在差异;女性发病率高于男性,4~20岁为主要易感人群,全年均可发,以冬季为高发期。

Objective To analyze Mycoplasma pneumoniae （MP） IgM antibody testing results in in 2013, and to understand the infection information and epidemiological characteristics of pathogens. Nanning Methods Sera Mycoplasma pneumoniae （MP） antibodies detection were performed by using passive gelatin particle agglutination in 9115 patients suspected-diagnosed with respiratory tract infection. Results Of 9115 cases, 4558 cases of 50.00% positive results were obtained, the positive rate of 46.75% was obtained in males test, and the positive rate of 54.13% was obtained in females test. Infection incidences of females were higher than males, there was statistically significant difference （ P 〈0.05）. In different age group, the highest positive rates of 60.60% and 69.89% were obtained in people aged over 4 years and in people aged over 8 years, respectively. The lower positive rates of 28.00% and 28.26% were obtained in infants under age 1 and in patients over the age of 60, the difference between the age groups was statistically significant （ P d0.05）. MP infection occurred in the whole year, the incidence rate was highest in winter; the difference between the season groups was statistically significant （ P 〈0.05）. Conclusion Mycoplasma pneumoniae infection in Nanning city in 2013 in relation to gender, age, season, there are significant differences. Infection incidences of females were higher than males. People aged 4 - 20 years was the main vulnerable group. MP infection occurred in the whole year, the incidence rate was highest in winter.
