上海市普陀区病原学阳性敏感肺结核患者家庭内密切接触者结核感染筛查情况及发病影响因素分析OACSTPCD
Screening of latent tuberculosis infection and analysis of morbidity influencing factors in household contacts of positive and sensitive pulmonary tuberculosis patients in Putuo District,Shanghai
目的:分析上海市普陀区病原学阳性敏感肺结核患者家庭内密切接触者结核分枝杆菌潜伏感染(latent tuberculosis infection,LTBI)发病情况及其影响因素.方法:采用前瞻性研究方法,以2018-2021年上海市普陀区确诊的病原学阳性敏感肺结核患者及其家庭内密切接触者为研究对象,采用γ-干扰素释放试验对密切接触者开展结核感染筛查,并在首次调查后的3、6、12个月内向密切接触者提供自愿的LTBI检测,计算LTBI累计感染率;采用二分类logistic回归方法分析指示病例特征对家庭内密切接触者发生LTBI的影响,并通过结核病登记报告系统随访识别密切接触者中活动性肺结核发病情况,计算其近期(截至2022年12月31日)的人年发病密度.结果:2018-2021年共纳入确诊肺结核患者168例,识别家庭内密切接触者284名,首次筛查LTBI感染率为26.8％(76/284),一年内累计感染率为34.5％(98/284).多因素分析结果显示,在第2个月末痰检结果仍为阳性的指示病例是家庭内密切接触者发生LTBI的危险因素(OR=7.167,95％CI:2.399～26.587,P=0.001).284名家庭内密切接触者共观察了720.17人年,5例新发现肺结核患者近期发病密度为6.94/1000人年(5/720.17人年),LTBI阳性肺结核近期发病密度[15.76/1000人年(4/253.83人年)]与LTBI阴性肺结核[2.14/1000人年(1/466.34人年)]差异无统计学意义(x2=2.607,P=0.106).结论:结核病患者家庭内密切接触者结核病感染风险高,尤其是第2个月末痰检结果仍为阳性的指示病例家庭内密切接触者发生LTBI的风险更高,应加强涂阳结核病患者的及时诊断和有效治疗,有效预防结核病在家庭内密切接触者中的传播.
Objective:To analysed the screening of latent tuberculosis infection(LTBI)and the morbidity influencing factors in household contacts of positive and sensitive pulmonary tuberculosis(PTB)patients in Putuo District,Shanghai.Methods:This was a prospective study,the study subjects were the household contacts of positive and sensitive PTB patients who tested for Mycobacterium tuberculosis infection by y-interferon release test in Putuo District from 2018 to 2021.After the first screen,the household contacts were followed up and tested for LTBI voluntarily within 3,6,12 months to calculate the cumulative infection rate.Binary logistic regression were used to analyze the risk factors of index cases on the LTBI of household contacts.The new cases were identified through the Tuberculosis Registration and Reporting System and short-term(end 202-12-03)incidence density of TB in household contacts were calculated.Results:From 2018 to 2021,a total of 168 PTB cases and 284 household contacts were enrolled in the study.The infection rate of the first screening test was 26.8％(76/284)and the cumulative infection rate was 34.5％(98/284)within one year.The results of multivariate analysis showed that the positive 2-month sputum examination of index cases was a risk factor for LTBI in household contacts(OR=7.167,95％CI:2.399-26.587,P=0.001).The short-term incidence density of 284 household contacts was 6.94/1000 person-years with 720.17 observation person-years.Five new cases were detected among and the short-term incidence density was 6.94/1000 person-years(5/720.17 person-years).There were no significant difference in the incidence density of PTB between LTBI household contacts(15.76/1000 person-years(4/253.83 person-years))and non-infected individuals(2.14/1000 person-years(1/466.34 person-years))(x2=2.607,P=0.106).Conclusion:The infection risk was high in household contacts of PTB patients.Index cases with positive 2-month sputum examination result had higher risks of generating LTBI.The timely diagnosis and effective treatment of smear-positive household contacts should be strengthened to effectively prevent the spread of tuberculosis in household contacts.
