Platelets, conventionally recognized for their pivotal roles in hemostasis and thrombosis, have emerged as multifunctional players in immune responses. In the context of Human Immunodeficiency Virus (HIV) infection, platelets exhibit intricate interactions influencing viral pathogenesis, immune activation, and disease progression. This review aims to provide an in-depth analysis of the diverse roles played by platelets in modulating HIV infection, shedding light on their impact on viral dynamics, immune responses, and associated pathophysiological processes. The paper addresses platelet-driven alterations in coagulation pathways and endothelial function in the context of HIV, emphasizing their role in HIV-associated coagulopathies, endothelial activation, and consequent vascular dysfunction. Additionally, the involvement of platelets in the development of HIV-associated comorbidities such as cardiovascular complications, neurocognitive impairment, and systemic inflammation is discussed, delineating platelet-driven mechanisms contributing to the pathogenesis of these conditions and their implications for disease outcomes. In conclusion, the multifaceted roles of platelets in HIV infection underscore their significance beyond hemostasis, offering potential insights into therapeutic avenues and highlighting the need for further investigations to decode the complexity of platelet-driven modulation of HIV infection.

Antiretroviral therapy (ART) has revolutionized the management of HIV infection, significantly reducing morbidity and mortality in individuals living with the virus. However, the influence of ART on maternal eosinophil levels during pregnancy remains a topic of interest and debate. This review explores the current understanding of how ART affects eosinophil levels in pregnant women living with HIV, considering both the potential mechanisms underlying these changes and their clinical implications. Keywords such as HIV, antiretroviral therapy, pregnancy, eosinophils, immune response, and maternal health are utilized to delve into relevant literature and provide insights into this complex interaction. Understanding the impact of ART on maternal eosinophil levels can contribute to optimizing the management of HIV during pregnancy, ensuring maternal health, and promoting favorable pregnancy outcomes.
