Surveillance analysis of Mycobacterium tuberculosis and HIV co-infection in Liaoning Province from 2016 to 2021
Objective To analyze the surveillance of Mycobacterium tuberculosis/HIV(TB/HIV)co-infection in Liaoning Province from 2016 to 2021,providing a scientific basis for formulating future prevention and control measures applicable to the province-wide co-infection.Methods A descriptive analysis was conducted on patient registration,two-way screening,and treatment information from the annual report of patients with TB/HIV co-infection in Liaoning Province from 2016 to 2021.Results From 2016 to 2021,222 cases of TB/HIV co-infection were registered in Liaoning Province,accounting for 0.16％(222/136 709)of TB patients and 1.42％(222/15 584)of HIV/AIDS patients.In HIV/AIDS,the symptom screening rate was 96.01％,showing a downward trend(x2trend=982.28,P＜0.05).The TB detection rate was 0.47％,also showing a downward trend(x2trend=36.56,P＜0.05),while the chest radiograph or sputum detection rate was 94.61％,showing an overall upward trend(x2trend=96.5,P＜0.05).Among TB patients,65 188 were tested for HIV antibodies,with a detection rate of 47.68％,which showed an overall upward trend(x2trend=3 326.38,P＜0.05).There were 39 HIV-positive cases detected,with the positive detection rate in TB patients decreasing from 0.12％to 0.07％.From 2016 to 2021,the majority of co-infected patients were male and ≥15 years old,with 496 cases(92.36％)of males and 41 cases(7.64％)of females.Among the 537 patients with co-infection,47 cases(8.75％)received anti-tuberculosis therapy alone,72 cases(13.41％)received anti-HIV therapy alone,and 408 cases(75.98％)received combined therapy,with an overall downward trend(x2trend=9.54,P＜0.05).Conclusions Focus should be placed on the male population and those aged ≥15 years,with future efforts aimed at enhancing two-way screening work among TB and HIV/AIDS patients and improving the rate of combined treatment.
