Elite Journal of Medical Sciences, 2024; 2(9):85-97 1 Understanding the Relationship between Aplastic Anemia and HIV: A Review *Emmanuel Ifeanyi Obeagu Department of Medical Laboratory Science, Kampala International University, Uganda. *Corresponding authour: Emmanuel Ifeanyi Obeagu, Department of Medical Laboratory Science, Kampala International University, Uganda, emmanuelobeagu@yahoo.com, ORCID: 0000-0002- 4538-0161 Abstract Aplastic anemia (AA) is a rare and life-threatening condition characterized by bone marrow failure, leading to pancytopenia and severe immunosuppression. The interplay between AA and human immunodeficiency virus (HIV) infection presents a complex clinical challenge, as HIV can exacerbate bone marrow dysfunction through direct viral effects, chronic immune activation, and antiretroviral therapy (ART)-related myelotoxicity. This review explores the intricate relationship between AA and HIV, highlighting the pathophysiological mechanisms, clinical manifestations, diagnostic challenges, and prognostic factors that influence patient outcomes. Effective management of AA in the context of HIV requires a comprehensive, individualized approach that balances the need for restoring hematopoiesis, controlling HIV replication, and preventing opportunistic infections. Key management strategies include optimizing ART regimens to minimize myelotoxicity, considering immunosuppressive therapy (IST) in severe cases, and exploring hematopoietic stem cell transplantation (HSCT) as a potential curative option. Supportive care, including transfusions, infection prevention, and nutritional support, plays a critical role in stabilizing patients and improving quality of life. Keywords: Aplastic anemia, HIV, bone marrow failure, pancytopenia, immunosuppression Introduction Aplastic anemia (AA) is a rare hematologic disorder characterized by the failure of bone marrow to produce sufficient blood cells, leading to pancytopenia—a reduction in red blood cells, white blood cells, and platelets. The condition can result in severe anemia, increased susceptibility to infections, and a higher risk of bleeding due to thrombocytopenia. The etiology of AA is diverse, with causes ranging from genetic predispositions and autoimmune disorders to environmental exposures such as radiation, chemicals, and certain medications. Viral infections, including those caused by hepatitis viruses and Epstein-Barr virus, are also recognized as potential triggers of AA.
