Antiretroviral Treatment Failure and Associated Factors Among HIV-Infected Children on Antiretroviral Therapy: A Retrospective Study.

Background HIV/AIDS-associated morbidity and mortality have reduced since the introduction of antiretroviral therapy (ART). Treatment failure is one of the causes of mortality, morbidity, and the development of drug-resistant viral strains. Therefore, this research aims to assess the prevalence and associated factors of treatment failure among children with HIV/AIDS on antiretroviral therapy attending the University of Gondar Specialized Referral Hospital, Northwest Ethiopia. Methods A retrospective study was conducted on 200 children registered for ART from 2005 to 2017. Data regarding patients' socio-demographic, baseline clinical characteristics, and treatment-related information were collected through a review of their medical records. Data were entered into Epi-info version 3.5.3 and analyzed using statistical package for social sciences (SPSS) version 21 software. To summarize characteristics of the study participant's descriptive statistics were done. Bivariable and multivariable binary logistic regression were fitted to identify factors associated with treatment failure. The odds ratio and 95% confidence interval (CI) were calculated to assess the strength of the association and P-value 36 months) (AOR= 1.01; 95% CI: 1.34-2.89), and regimen change (AOR=9.22; 95% CI: 3.36-25.03) were factors of ART failure. Conclusion In this study, there is significant treatment failure among HIV-infected children. Having co-infection, being on ART for a long period, regimen change, and being male were found to be independent factors of treatment failure in children. Therefore, timely identification and monitoring of ART failure should be necessary to enhance the benefit and to prevent further complications. Prophylaxis for opportunistic infections such as co-trimoxazole preventive therapy should continue to recover the immunological status of the child.
