Investigation of pulmonary Legionella pneumophila infections in 1951 patients

目的调查医院1951例肺部嗜肺军团菌感染患者状况。方法收集医院2011年1月1日-12月31日呼吸科门诊和住院肺部感染患者血清标本1951份,采用军团菌属(Lp)抗体快速金标记检定卡进行嗜肺军团菌IgG抗体的检测;采用SPSS 12.0统计软件进行统计分析。结果 2011年1-12月嗜肺军团菌感染率分别为:0、0、3.33%、3.57%、3.45%、0、0.90%、0、0、2.11%、11.17%、17.09%,3-5、10-12月嗜肺军团菌感染率较高,其中12月份最高;男性感染率为2.90%,女性为3.59%,男女性嗜肺军团菌感染率差异无统计学意义;14～20、21～30、31～40、41～50、51～60、61～70、>70岁组患者嗜肺军团菌感染率分别为:5.66%、7.14%、5.08%、5.03%、4.44%、1.68%、1.89%,>61岁老年患者嗜肺军团菌感染率较低,而14～60岁年龄段嗜肺军团菌感染率较高,其中21～30岁组嗜肺军团菌感染率最高。结论秋冬季和春季是嗜肺军团菌的高发季节;嗜肺军团菌感染无性别的差异;嗜肺军团菌感染有年龄的差异,>61岁老年患者嗜肺军团菌感染较低,中青年嗜肺军团菌感染率较高。

OBJECTIVE To investigate the status of pulmonary Legionella pneumophila （LP） infections in 1951 sufferers in Wuxi. METHODS A total of 1951 serum specimens from 1951 pulmonar.y infection sufferers with respiratory diseases treated in the hospital from Jan 1st, 2011 to Dec 31st, 2012 were collected and the LP：IgG was tested with a g01d rapid screen test card ,the data were analyzed by using the SPSS 12.0 software. RESULTS The positive rates of LP infections in Jan--Dec 2011 were respectively as follows ：0, 0,3.33%, 3.57%, 3.45%, 0, 0.90% ,0,0,2.11%, 11： 17% ,and 17.09% ,which were higher in March, April, May, October, November and December, with the ＇highest in December. The positive rates of the males and females were 2. 90% and 3.59%, respectively, the difference in the infection rate between the two genders was not statistically significant. The positive rate of LP infections as 5.66% in the 14 20 age group, 7.14% in the 21-30 age group, 5.08% in the 31-40 age group, 5.03% in the 41-50 age group, 4.44% in the 51-60 age group, 1.68% in the 61-70 age group ,and 1.89% in the more than 70 age group, and the positive rate of LP infections in the patients with more than 61 years of age was relatively low, which was relatively high in the 14-60 age group of patients and was highest in the 21-30 age group of patients. CONCLUSION LP infection is correlated with the season and tends to burst in the autumn-winter period and spring. Additionally, the LP infection dose not differ between the genders but between the age. The positive rate of the LP infection is relatively low in the patients aged more then 61 years old and is highest in the young adults.
