[The role of biomedical interventions in HIV prevention: Pre-exposure Prophylaxis (PrEP)]

Knowledge domain and emerging trends in HIV pre-exposure prophylaxis: A visualization analysis via CiteSpace

Background

As an effective strategy that reduces transmission among people at high risk of human immunodeficiency virus (HIV), pre-exposure prophylaxis (PrEP) has revolutionized HIV prevention. Our study aims to provide a reference for the development of relevant research and the formulation of prevention and control policies for HIV.

Methods

Through CiteSpace software, this study aims to present a comprehensive overview of the HIV PrEP knowledge structure, hotspots, and frontiers. We searched the Web of Science Core Collection for studies published between 2012 and 2022 related to HIV PrEP, and 3,243 papers remained after selection.

Results

The number of HIV PrEP publications has increased over the past few years. A close integration and exchange of HIV PrEP research findings has taken place between countries and authors. Major ongoing research trends include long-term injection PrEP, the impact of chlamydia on HIV PrEP, and individual awareness of and attitudes toward HIV PrEP. Thus, more attention should be paid to innovations and breakthroughs in drugs, the factors that affect HIV transmission and susceptibility, and the future promotion of public acceptance of HIV PrEP.

Conclusion

This study offers a systematic, objective, and comprehensive analysis of the related articles. It will assist scholars in understanding the dynamic evolution of HIV PrEP research and identifying future research areas to better advance the development of the field.

Antiretroviral Therapy-Induced Dysregulation of Gene Expression and Lipid Metabolism in HIV+ Patients: Beneficial Role of Antioxidant Phytochemicals

Human immunodeficiency virus (HIV) infection has continued to be the subject of study since its discovery nearly 40 years ago. Significant advances in research and intake of antiretroviral therapy (ART) have slowed the progression and appearance of the disease symptoms and the incidence of concomitant diseases, which are the leading cause of death in HIV+ persons. However, the prolongation of ART is closely related to chronic degenerative diseases and pathologies caused by oxidative stress (OS) and alterations in lipid metabolism (increased cholesterol levels), both of which are conditions of ART. Therefore, recent research focuses on using natural therapies to diminish the effects of ART and HIV infection: regulating lipid metabolism and reducing OS status. The present review summarizes current information on OS and cholesterol metabolism in HIV+ persons and how the consumption of certain phytochemicals can modulate these. For this purpose, MEDLINE and SCOPUS databases were consulted to identify publications investigating HIV disease and natural therapies and their associated effects.
