Incidence and predictors of tuberculosis among children on antiretroviral therapy at northeast Ethiopia comprehensive specialized hospitals, 2022; A multicenter retrospective follow-up study
Abstract
Introduction: Around the world, tuberculosis (TB) is the most common cause of mortality and morbidity in both adults and children. The incidence of tuberculosis (TB) is increased worldwide by co-infection with the human immunodeficiency virus (HIV), particularly in Sub-Saharan Africa. As a result, the study aimed to determine the incidence and predictors of tuberculosis among children on antiretroviral therapy at northeast Ethiopia Comprehensive Specialized Hospitals. Methods: An institution-based retrospective follow-up study was carried out in northeast Ethiopia’s Comprehensive Specialized Hospitals, among 362 children on antiretroviral therapy from January 1, 2007, to September 30, 2021. The data were entered into Epi Data version 4.6.1 and then exported to STATA version 16 for analysis. Bivariate and multivariable Cox proportional hazards model was used to discover tuberculosis predictors. Variables with a p-value of <0.05 at 95% confidence intervals in the multivariable Cox proportional hazard model were considered statistically significant. Results: Among the 358 Human Immunodeficiency Virus-infected children, two-thirds (69.3%) were over ten years old. The overall tuberculosis incidence rate was 2.0 (95%CI: 1.5–2.6) per 100 person-years with a total of 2452 years of observations. WHO clinical stages III and IV [AHR: 3.2 (95% CI 1.8–5.5)], being severely stunted [AHR = 2.1 (95% CI, 1.5–358)], and “Fair” and “poor” adherence levels to antiretroviral therapy [AHR = 4.0 (95% CI 1.5–10.8)] were independent predictors of tuberculosis. Conclusion: The incidence of tuberculosis in children infected with HIV/AIDS was high in this study. The risk of tuberculosis (TB) in HIV/AIDS-infected children has been linked to WHO stages III and IV, severe stunting, and ''Fair'' and ''Poor'' ART adherence. As a result, children with HIV/ADIS should be evaluated on a regular basis in order to improve the quality of ART services and reduce the incidence rate of tuberculosis among children.
