In 2022, mpox virus spread globally with 99% of cases in non-endemic countries. People living with HIV (PLHIV) are disproportionally affected, often with more severe clinical features and outcomes. The AAD/ILDS Dermatology COVID-19, Monkeypox (mpox), and Emerging Infections registry captured mpox cases from 13 non-endemic countries in a de-identified REDCap registry. We aimed to examine cutaneous symptomatology and outcomes in cases of mpox in PLHIV. Of 119 reported cases, 44 were PLHIV (35%). Cases were 98% male, with a median age of 38 years, located in Europe (57%) and the U.S. (39%). Nearly half of PLHIV reported skin lesions as their initial sign (45%), and 43 (98%) reported skin lesions during illness. The primary initial lesion locations were peri-anal (34%) and genito-inguinal (34%). Co-infection with other sexually transmissible infections (STI) was more common in PLHIV, 57% vs. 38% in all-registry cases (p<0.01). The most common co-infections were gonorrhea, syphilis, and chlamydia. Time to resolution was 17 days, 3 days shorter than all-registry cases, which may be due to higher use of Tecovirimat in PLHIV (36% vs. 25% in all-registry cases; p<0.01). There were no differences in the frequency of hospitalization or scarring. One death was reported. Overall, cutaneous lesion count was similar in PLHIV and all-registry cases. Lesion location was more frequently reported in the peri-anal and genito-inguinal regions. Sample size was insufficient to detect differences in length of infection, hospitalization, or scarring in PLHIV. Co-infections were more common in PLHIV, highlighting a need for co-testing for STIs during mpox evaluation.
