韶钢社区老年人有症状尿路感染与无症状性菌尿病原菌分布特点研究

Study on the pathogen distribution characteristics of symptomatic urinary tract infection and asymptomatic bacteriuria in the elderly of Shaogang community

目的探讨韶钢社区老年人有症状尿路感染与无症状性菌尿病原菌分布特点。方法 300例尿微生物培养结果阳性老年患者为研究对象,依据是否出现尿路感染症状分为无症状组(232例)和有症状组(68例)。分析比较两组一般资料、实验室检测结果、病原菌感染特点。结果无症状组年龄(71.3±4.6)岁大于有症状组的(68.5±3.7)岁,差异具有统计学意义(P<0.05);两组性别、合并疾病对比,差异均无统计学意义(P>0.05)。两组患者主要感染菌群均为革兰阴性菌大肠埃希菌,无症状组为37.50%(117/312),有症状组为38.46%(30/78);其次为革兰阳性菌屎肠球菌,无症状组为12.50%(39/312),有症状组为12.82%(10/78)。无症状组尿白细胞含量(142.5±13.2)个/μl明显低于有症状组的(718.3±25.8)个/μl,差异具有统计学意义(P<0.05);两组尿细菌含量对比,差异无统计学意义(P>0.05)。结论老年人尿路感染发病率较高,且以无症状性为主,感染菌群主要为革兰阴性菌,其次为革兰阳性菌,且无症状患者尿白细胞含量明显低于有症状患者,但两者尿细菌含量差异不明显。

Objective To discuss the pathogen distribution characteristics of symptomatic urinary tract infection and asymptomatic bacteriuria in the elderly of Shaogang community. Methods A total of 300 elderly patients with positive results of urine microbial culture were divided into two groups: asymptomatic group(232 cases) and symptomatic group(68 cases). The general data, laboratory test results, and pathogen infection characteristics of the two groups were analyzed and compared. Results The age(71.3±4.6) years old of asymptomatic group was older than that of symptomatic group(68.5±3.7) years old, and the difference was statistically significant(P<0.05). There was no statistically significant difference in gender and comorbidities between the two groups(P>0.05). The main infection bacteria in the two groups were gram-negative Escherichia coli, with 37.50%(117/312) in the asymptomatic group and 38.46%(30/78) in the symptomatic group, followed by gram-positive Enterococcus faecium, with 12.50%(39/312) in the asymptomatic group and 12.82%(10/78) in the symptomatic group. Urine leukocyte content(142.5±13.2) pieces/μl in asymptomatic group was significantly lower than that in symptomatic group(718.3±25.8) pieces/μl, and the difference was statistically significant(P<0.05). There was no statistically significant difference in urine bacterial content between the two groups(P>0.05). Conclusion The elderly have a higher incidence of urinary tract infections, and they are mainly asymptomatic, and the infection flora is mainly Gram-negative bacteria, followed by Gram-positive bacteria, and the content of urine leukocytes in asymptomatic patients is significantly lower than that of symptomatic patients, but the difference in urine bacterial content is not obvious.
