Hematological changes among HIV-Positive persons on antiretroviral therapy at a tertiary hospital in Ghana

Abstract

BACKGROUND: Haematological abnormalities such as anaemia, leucopenia, and thrombocytopenia are common complications of Human Immunodeficiency Virus (HIV) infection. Few researchers have studied the changes in HIV positive patients before and during antiretroviral therapy (ART) in Ghana. This study is aimed at determining the haematological profile of people living with HIV (PLHIV) at baseline and whilst on ART in a tertiary facility in Cape Coast, Ghana. METHODS: This was an analytical cross-sectional study with a retrospective component among PLHIV assessing ART services at the Cape Coast Teaching Hospital, Ghana. Full blood count (FBC) test was performed on blood samples and the results were analyzed and categorized based on WHO definitions. RESULTS: A total of 440 participants were included. The mean haemoglobin level (g/dL) for females at baseline, 6 months after ART and during this study were 9.6 (±1.8), 10.9 (±1.4) and 11.6 (±1.4); and 10.2 (±2.1), 11.6 (±1.7) and 11.8 (±1.6) for males. At baseline, the commonest type of anaemia for both females and males was microcytic hypochromic anaemia. The mean platelet count was 382 x 109/l at baseline but reduced to 298 x 109/L after 6 months on ART. Among male participants in this study, the main factor associated with being anaemic after 6 months on ART was the ART regimen with non-Zidovudine based regimen, having reduced odds of anaemia of OR 0.3 (95%CI 0.1 – 0.9), pvalue of 0.04. Among females, having plasma viral load >1000 copies per ml was found to have increased odds of being anaemic (OR 1.4, 95%CI 0.7 – 2.6), though not statistically significant (P-value of 0.32). CONCLUSION: The prevalence of anaemia, though improved on ART, was high among PLHIV. It is essential to ensure that full blood count of PLHIV in Ghana are done regularly, at all levels of service provision, with appropriate referral systems in place. The change to the current TDF based preferred first line ART regimen must also be enforced to reduce the potential risks associated with AZT use. This will improve outcome for PLHIV.
