RESUMO
Early UK surveillance data revealed that people living with HIV were overrepresented among cases of monkeypox (mpox). However, it remains unknown whether mpox infection is more severe in people living with well-controlled HIV. All laboratory-confirmed mpox cases presenting between May and December 2022 to one London hospital service were identified via pathology reporting systems. We extracted demographic and clinical data to allow comparison of clinical presentation and severity of mpox among people with and without HIV. We identified 150 people with mpox (median age 36 years, 99.3% male, 92.7% reporting sex with other men). HIV status was available for 144 individuals, 58 (40.3%) of whom were HIV positive (only 3/58 had CD4 cell counts <200 cells/mm3 and 5/58 had HIV RNA >200 copies/mL). People with HIV had similar clinical presentations to those without HIV, including indicators of more widespread disease, such as extragenital lesions (74.1% vs. 64.0%, p = .20) and nondermatological symptoms (87.9% vs. 82.6%, p = .38). People with HIV also experienced a similar time from onset of symptoms to discharge from all inpatient or outpatient clinical follow-up (p = .63) and total time under follow-up (p = .88) compared with people without HIV. A similar proportion of people with HIV required review in the hospital emergency department (36.2% vs. 25.6%, p = .17) or admission to hospital (19.0% vs. 9.3%, p = .09). There were no recorded deaths. In this cohort of people with mpox, there was a high prevalence of HIV coinfection, the majority of which was well-controlled. We find no evidence that people with well-controlled HIV experienced more severe mpox infection.
