Comparison of clinical manifestations in mpox patients living with HIV versus without HIV: A systematic review and meta‐analysis

Abstract

AbstractCurrently, many cases of mpox patients living with the human immunodeficiency virus (HIV) have been reported. Immunocompromised mpox patients, including those living with HIV are noted for an increased risk for severe symptoms; however, existing studies did not focus on the statistical comparison of mpox outcomes associated with HIV. Thus, we conducted a systematic review and meta‐analysis to evaluate and compare the clinical manifestations of mpox in people living with HIV (PLWH) and people without HIV. In this systematic review and meta‐analysis, PubMed/MEDLINE, Embase, and Google Scholar were searched up to March 7, 2023. A random effects model was used to calculate the pooled prevalence along with the 95% confidence intervals (CI), and the odds ratio and its corresponding 95% CIs were calculated to elucidate the significance of each clinical feature for mpox patients with and without HIV. In this study, we included 99 published papers with 2413 patients with mpox (median age, 35.5 years; PLWH n = 1151) from 27 countries across six continents. The odds ratio of the mpox outcomes with PLWH in comparison to patients without HIV was found to be significant for skin rash (1.24, 95% CI: 1.01–1.53), proctitis (2.03, 95% CI: 1.36–3.04), cough (0.57, 95% CI: 0.33–0.98), and diarrhea (3.85, 95% CI: 1.24–11.98). The odds ratio of mpox patients with HIV for historical infections of syphilis was 2.14 (95% CI: 1.38–3.32), compared with those without HIV. This is the first international and comprehensive study that performed a systematic review and meta‐analysis to statistically measure mpox manifestations according to HIV status. As clinical features related to mucosal contact were characteristically pronounced in PLWH, our systematic review provides insight that the primary invasion site of infection strongly relates to the outcomes of mpox.
