Prevalence of Mycobacterium tuberculosis and HIV co-infections in Zhenjiang City from 2014 to 2021
Objective To investigate the prevalence of Mycobacterium tuberculosis and HIV co-infections in Zhenjiang City from 2014 to 2021,so as to provide insights into improvements in the control strategy for M.tuberculosis and HIV co-infections.Methods The dual screening of tuberculosis cases and HIV-infected individuals,and the registration,treatment and prognosis of cases with M.tuberculosis and HIV co-infections were collected from National Tuberculosis Management Information System of China and Zhenjiang Municipal annual report tables for management of M.tuberculosis and HIV co-infections and analyzed.Results A total of 1228 newly reported HIV-infected patients were detected in Zhenjiang City from 2014 to 2021,with a tuberculosis screening rate of 99.10％and a tuberculosis detection rate of 1.15％(14 cases),and 6 303 previously reported HIV-infected cases were identified,with a tuberculosis screening rate of 99.76％and a tuberculosis detection rate of 0.14％(9 cases).A total of 9 801 newly reported tubercu-losis cases were identified in Zhenjiang City from 2014 to 2021,with an HIV screening rate of 76.78％and a positive HIV detection rate of 0.07％(5 cases).The proportion of tuberculosis screening was all＞98％ among HIV-infected patients across the city,and the percentage of HIV screening was all＞60％ among tuberculosis patients across the city.Among 28 patients with M.tuberculosis and HIV co-infections,22 cases underwent simultaneously anti-tuberculosis therapy and antiretroviral treatment(78.57％),one case receiving antiretroviral treatment alone(3.57％),2 cases undergoing anti-tuberculosis therapy(7.14％)and 3 cases untreated(10.71％).Of 24 patients with M.tuberculosis and HIV co-infections that underwent anti-tuberculosis therapy,19 cases received successful anti-tuber-culosis therapy,with a success rate of 79.17％.Conclusions Dual screening is an important approach for early identification of M.tu-berculosis and HIV co-infections.Notably,screening of tuberculosis among newly reported HIV-infected individuals facilitates early iden-tification of M.tuberculosis and HIV co-infections.
