Selenium and zinc supplementation in HIV-infected patients


Background: The Human Immunodeficiency Virus (HIV) epidemic is still a public health concern. Micronutrient deficiencies can fasten the progression of this syndrome. Selenium and zinc are essential trace elements, which exert antioxidant and anti-inflammatory activities in HIV infection. The present overview aimed to evaluate the current knowledge from systematic reviews (SRs) of the effects of selenium and zinc supplementation in HIV patients to show the most updated and comprehensive summary of previous SRs. Methods: The current study was performed according to the guidelines of the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) statements. To assess the quality of articles we used the Measurement Tool to Checklist Assess Systematic Reviews (AMSTAR). PubMed/Medline, Web of Science, Scopus, and EMBASE databases and Google Scholar web search engine were searched up until March 2022, using relevant keywords. Results: Among 3731 articles assessed, five and four studies met the inclusion criteria for selenium and zinc supplementation, respectively. Four studies found that selenium supplementation can be effective in delaying CD4 decline in HIV-infected patients. In four SRs, the dosage of selenium supplementation was 200 μg/day. Three studies, however, reported no significant effect of zinc supplementation on CD4 cell counts, and HIV viral load. The dosage of zinc supplementation ranged from 12 to 100 mg/day. The intervention duration ranged from 2 weeks to 18 months. Conclusion: In the present study, we identified some clinical evidence of a potential beneficial effect of selenium supplementation in HIV-infected patients.
