TOPLINE:
.
METHODOLOGY:
- There is limited information on the populations disproportionately affected by the recent global mpox outbreak, particularly in individuals with HIV and racial and ethnic minorities.
- To investigate morphologic and clinical presentations of mpox in diverse populations, researchers conducted a review of the records of 54 individuals (mean age, 42.4 years) diagnosed with mpox at a San Francisco clinic for patients with HIV or at high risk for HIV, between June and October 2022.
- All patients were assigned male at birth, and three identified themselves as transgender women.
- Morphologic descriptions were documented through either photographic evidence or physical examination notes.
TAKEAWAY:
- Pustules or pseudopustules were the most common morphologic finding in 57.1% of the White non-Hispanic patients and 62.5% of the patients of color (P = .72).
- White non-Hispanic patients were more likely to have no prodromal symptoms (50.0% vs 17.5%; P = .02) and were more likely to have genital lesions (78.6% vs 40.0%; P = .01) than patients of color. These differences were significant or nearly significant when White non-Hispanic patients were compared with Hispanic patients but not in other ethnic or racial groups.
- There were no differences in HIV viral loads or CD4 counts between racial and ethnic groups, and no variations in clinical presentations were observed based on CD4 counts.
- Patients with higher HIV viral loads were more likely to have concurrent sexually transmitted infections (57.1% vs 25%; P = .03).
- Symptoms resolved in all patients, regardless of medical intervention, within weeks of initial presentation, and there were no hospitalizations or deaths.
IN PRACTICE:
Considering that HIV viral burden was not significantly different between White non-Hispanic patients and patients of color, the difference in presentation of the prodrome “may indicate disparities in vulnerable populations,” the authors wrote, noting that more research in large groups is needed to confirm their results.
SOURCE:
The study, led by Richard W. Kim, BS, from the University of California San Francisco, was published online in the Journal of the American Academy of Dermatology.
LIMITATIONS:
Inclusion of “other” racial category in the records highlighted potential inaccuracies in data representation.
DISCLOSURES:
The study received no external funding. The authors did not declare any competing interests.
