Long or complicated mpox in patients with uncontrolled HIV infection

# metadata.dc.description.abstract[].value
To date, former research about the impact of HIV infection on mpox poor outcomes is still limited and controversial. Therefore, the aim of this study was to assess the impact of HIV on the clinical course of mpox, in a large population of patients from Spain. Nationwide case-series study. Patients from 18 Spanish hospitals, with PCR-confirmed mpox from April 27, 2022 to June 30, 2023 were included in this study. The main outcome was the development of long or complicated (LC) mpox, defined as: (i) duration of the clinical course >= 28 days, or; (ii) disseminated disease, or: (iii) emergence of severe complications. One thousand eight hundred twenty-three individuals were included. Seven hundred eighty-six (43%) were people living with HIV (PLWH), of whom 11 (1%) had a CD4 cell count<200 cells/mm(3) and 33 (3%) <350 cells/mm(3). HIV viral load >= 1000 cp/mL was found in 27 (3%) PLWH, none of them were on effective ART. Fifteen (60%) PLWH with HIV-RNA >= 1000 cp/mL showed LC versus 182 (29%) PLWH with plasma HIV-RNA load<1000 copies/mL and 192 (24%) individuals without HIV infection (p<0.001). In multivariate analysis, adjusted by age, sex, CD4 cell counts and HIV viral load at the time of mpox, only plasma HIV-RNA >= 1000 cp/mL was associated with a greater risk of developing LC mpox [adjusted OR=4.06 (95% confidence interval 1.57-10.51), p=0.004]. PLWH with uncontrolled HIV infection, due to lack of ART, are at a greater risk of developing LC mpox. Efforts should be made to ensure HIV testing is carried out in patients with mpox and to start ART without delay in those tested positive.
