Prevalence and Predictors of Cytopenias in HIV-Infected Adults at Initiation of Antiretroviral Therapy in Mehal Meda Hospital, Central Ethiopia.

BACKGROUND

Hematologic abnormalities are common complications of patients infected with HIV associated with accelerated deterioration in CD4+ cell counts, disease progression, poor quality of life and death. Few studies have evaluated the magnitude of cytopenias at the initiation of antiretroviral therapy (ART) in sub-Saharan Africa. The aim of this study was to determine the prevalence and predictors of cytopenias among HIV-infected adults at initiation of ART in a resource-limited setting in Ethiopia.

METHODS

A cross-sectional study was conducted among HIV-infected adults initiating ART at the HIV care and treatment clinic of Mehal Meda Hospital between September 2008 and June 2019. Demographic, clinical and laboratory data of patients were collected from medical records. Anemia was defined according to WHO guidelines as hemoglobin concentration <12 g/dl for non-pregnant females and <13 g/dl for males. Leucopenia was defined as total white blood cell count <4.0 × 10 cells/μL and thrombocytopenia as platelet count <150 × 10 cells/μL. Logistic regression analysis was used to determine factors associated with the presence of cytopenias.

RESULTS

Out of the total 566 patients included, 36.6% (95% CI 32.7-40.6%) had anemia, 17.1% (95% CI 14.2-20.4%) had leucopenia and 14.5% (95% CI 11.8-17.6%) had thrombocytopenia. A total of 53.2% (95% CI 49.1-57.3%) of patients had at least one form of cytopenia, 14.1% (95% CI 11.4-17.2%) had bicytopenia, and only 0.5% had pancytopenia. Factors associated with the presence of any cytopenia in multivariable analysis were male sex, advanced clinical disease stage, low CD4+ cell count, low BMI, and decreased renal function.

CONCLUSION

A substantial burden of cytopenias was detected among HIV-infected adults enrolled for care and treatment services in our setting. Patients with HIV infection should be screened for hematological abnormalities at initiation of ART because of its potential for morbidity and mortality during ART.
