Viral Load Pattern of HIV Positive Children and Adolescents Attending a Paediatric Infectious Diseases Clinic in Owerri, Nigeria

Abstract

Background: The Viral load (VL) test measures the number of copies of HIV RNA in one milliliter of blood and is the preferred antiretroviral therapy (ART) monitoring strategy. Viral suppression is defined as patients having ≤ 1000 copies of viral RNA/ml of blood.
 Methods/Materials: This study involved the retrospective review of viral load test result of patients aged 2-19years living with HIV/AIDS and enrolled in the treatment programme of the Paediatric infectious diseases clinic of the Federal University Teaching hospital Owerri.
 Results: 117 patients met the inclusion criteria and 103 were virally suppressed giving a suppression rate of 88%. Majority of those virally suppressed were in the 15-19 age group. A logistic regression analysis to ascertain the impact of age, gender, drug regimen, and duration on ARTs on the likelihood of viral suppression showed that age, gender, and drug regimen were not significant predictors of viral suppression (p > 0.05). However, duration on ARTs was a significant predictor (p < 0.01), with patients who had been on ARTs for greater than 24 months having higher odds of viral suppression (OR = 5.42, 95% CI = 1.84-15.93) compared to those who had been on ARTs for 0-6 months.
 Conclusion: Our study provides important insights into the viral load pattern of children and adolescents living with HIV/AIDS in Owerri. It highlights the importance of early initiation of ART, adherence to ART regimen, and routine viral load monitoring to achieve and maintain viral suppression.
