Magnitude and Factors Associated with Cytopenia Among Children on Highly Active Antiretroviral Therapy at Hawassa University College of Medicine and Health Science, Sidama Region, Southern Ethiopia.

Abstract

The most common abnormality in HIV-infected children is cytopenia, a hematological complication characterized by a decline in any of the blood cell lines. It is associated with a higher risk of morbidity and mortality. Therefore, this study aimed to assess the prevalence and associated factors of cytopenia among HIV-positive children on highly active antiretroviral therapy (HAART). Hospital-based cross-sectional study design was conducted on HIV-positive children on HAART from July to September 2020. Socio-demographic and clinical characteristics of the study participants' data were collected using a structured questionnaire. Hematological parameters from the blood sample were analyzed using Ruby Cell-Dyne 300 hematology auto-analyzer. The data were analyzed using SPSS version 20. Logistic regression was used to assess the predictors of cytopenia among the study participants. P-values of less than 0.05 are considered statistically significant. Two hundred seventy-three HAART-experienced children were enrolled in this study, and 50.9% were females. At baseline, 40.7% of children were anemic. The overall magnitude of cytopenia among the study participants was 26.7%. The prevalence of anemia, thrombocytopenia, leucopenia and neutropenia among children was 11.4%, 4.0%, 14.3%, and 18.3%, respectively. Patients with an undetectable viral load (AOR = 0.5, CI = 0.3-0.9) are 50% less likely to report cytopenia. HAART-experienced children living in rural areas are more likely to develop cytopenia (AOR = 2.6, CI = 1.3-5.2) than those living in urban areas. Hematologic abnormalities are common problems among children on highly active antiretroviral therapy. Therefore, routine investigation of hematological and immunological changes following appropriate therapeutic interventions is recommended.
