Monitoring HIV viral load and CD4+ T cell count is critical in managing AA, as these parameters provide insights into immune function and disease progression. This review examines the role of viral load and CD4+ count monitoring in the context of AA, highlighting how these indicators influence disease management and therapeutic outcomes. Effective management of AA in HIV-infected individuals requires a comprehensive approach that integrates regular monitoring with targeted therapeutic strategies. HIV viral load monitoring is essential for assessing the effectiveness of antiretroviral therapy (ART) and controlling HIV replication. High viral loads are associated with increased immune dysfunction and exacerbation of AA, making regular monitoring crucial for optimizing ART and preventing further bone marrow suppression. Similarly, CD4+ T cell count serves as a key marker of immune status and can guide treatment adjustments. A low CD4+ count reflects significant immunosuppression, which can worsen AA and increase infection risk, highlighting the need for ongoing assessment and management. Keywords: Aplastic anemia, HIV, viral load, CD4+ count, hematologic monitoring, Introduction Aplastic anemia (AA) is a severe hematologic disorder characterized by bone marrow failure, leading to pancytopenia and a range of clinical manifestations, including fatigue, bleeding, and susceptibility to infections. This condition results from the inadequate production of red blood cells, white blood cells, and platelets due to the compromised function of the bone marrow. In the
