Prevalence of Leucopenia and Associated Factors before and after Initiation of ART among HIV-Infected Patients, North East Ethiopia: Cross-Sectional Study.

Abstract

BackgroundLeucopenia is the commonest hematological abnormaly that occurs in patients with human immune deficiency virus (HIV) infection. The magnitude and related factors of leucopenia during the time of ART are not characterized in Ethiopia. This study aimed to assess the prevalence of leucopenia before and after the initiation of ART among HIV patients attending Debre Berhan Referral Hospital (DBRH), North East Ethiopia.MethodsA cross-sectional study was conducted from September to December 2020 in DBRH, North-East Ethiopia. A total of 272 patients on ART were selected by simple random sampling techniques. Socio-demographic and clinical characteristics of the study participants were collected by standard questionnaires. Measurements of leucocyte count and CD4 counts were made by Sysmex XT 2000i hematology analyzer and BD FACS count CD4 analyzer, respectively. Statistical analysis of data was done by SPSS version 23. Logistic regression was done and a P-value<0.05 was taken as statistically significant.ResultsThe prevalence of leucopenia, neutropenia, and lymphopenia were 20.9%, 7.0%, and 6.6% before initiation of ART and 15.4%, 1.1, and 4.4% after initiation of ART, respectively. There was a significant difference in total white blood cell count, absolute neutrophil count, and total lymphocyte count between patients on ART and ART naïve patients. HIV patients whose cluster of differentiation (CD4) counts were <200 cells/µL and patients on a zidovudine (AZT)-based regimen were more likely to have leucopenia than HIV patients whose CD4 counts were ≥ 200 cells/µL and on a tenofovir (TDF)-based regimen.ConclusionIn this study, the prevalence of leucopenia, neutropenia, and lymphopenia has shown a significant decrement after the initiation of ART. HIV patients with low CD4 count and on an AZT-based regimen are more likely to have leucopenia, neutropenia, and lymphopenia. Based on our findings, we recommend that the health care professional routinely investigate and should treat leucopenia.
