Association of HIV Infection and Hospitalization among Mpox Cases: a Systematic Review and Meta-Analysis

Mpox is a viral zoonotic disease that has seen a resurgence in recent years, with outbreaks reaching beyond its traditional endemic zones in Central and West Africa to parts of Europe and North America. The relationship between human immunodeficiency virus (HIV) infection and mpox outcomes, particularly hospitalization rates, remains underexplored despite the known immunosuppressive effects of HIV. This systematic review and meta-analysis aimed to clarify the association between HIV infection and the likelihood of hospitalization in mpox cases. A literature search was conducted through PubMed, Embase, Web of Science, Scopus, and the Cochrane Library up until August 10, 2024. The eligibility criteria focused on observational studies that evaluated hospitalization rates among mpox cases, distinguishing between HIV-positive and HIV-negative individuals. Newcastle-Ottawa Scale was used for evaluating study quality. The meta-analysis used a random-effects model to accommodate expected study heterogeneity using R software (V. 4.4). The search yielded 686 records, with 14 studies meeting the inclusion and exclusion criteria after screenings and full-text assessments. The pooled analysis revealed a 56.6
