Among these, the bone marrow, the primary site for hematopoiesis, undergoes substantial alterations during HIV infection, profoundly influencing erythropoiesis—the process of red blood cell production. Anemia, a prevalent hematologic complication in HIV-infected individuals, often serves as a marker of disease progression and impacts overall health outcomes. This paper aims to delve into the intricate relationship between HIV-associated bone marrow alterations and their consequential effects on erythropoiesis. The mechanisms underlying bone marrow changes in HIV infection, including direct viral effects, dysregulation of cytokine networks, and inflammatory processes, significantly disrupt the delicate balance necessary for efficient erythropoiesis. The impact of these alterations on erythropoiesis manifests through ineffective red blood cell production, decreased erythropoietin responsiveness, and shortened red blood cell lifespan. Chronic inflammation further complicates erythropoietic processes, contributing to the development and perpetuation of anemia in HIV-infected individuals. Therapeutic interventions encompass a multifaceted approach, including antiretroviral therapy (ART) to control viral replication, erythropoiesis-stimulating agents, and adjunctive nutritional support to manage anemia. However, emerging research targeting bone marrow microenvironmental factors and novel agents stimulating erythropoiesis offer promising avenues for future therapeutic development.
