Comparison of clinical course of Mpox among HIV‐negative and HIV‐positive patients: A 2022 cohort of hospitalized patients in Central Europe
Abstract
Mpox has become the most significant orthopoxviral infection among humans. Since May 2022, there has been a multicountry outbreak of mpox across six continents. Retrospective observational cohort study of 94 patients with probable or confirmed mpox of whom 86.2% were hospitalized in Hospital for Infectious Diseases in Warsaw, Poland between May 16 and October 30, 2022. Most patients were young (median age: 31, IQR: 25−43 years), predominantly (88.3%) Polish men who have sex with men exposed most commonly in Poland (82.7%), Spain (6.2%), or Germany (4.9%). The median observed mpox incubation period was 7 (IQR: 4−8) days with the median hospitalization time of 7 (range: 2−24, IQR: 5−11) days. History of sexually transmitted infections (STIs) was common in the group (previous syphilis or hepatitis C virus in 33.3% and 17.3%, respectively, 6.2% of early syphilis or gonorrhea). A significant proportion (n = 43, 45.7%) of mpox cases were people with human immunodeficiency virus (HIV), all except one were on stable and virologically effective (88.4% with HIV viral load 50 skin lesions the course of the disease was self‐limited with no severe cases or deaths. There were no significant clinical or laboratory differences or complication rates between patients with and without HIV coinfection. Epidemiological and clinical characteristics of mpox in Poland are similar to other countries, but there were no targeted, population oriented interventions or vaccination programs. Mpox…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 94 participants or records.
