Tecovirimat Treatment of People With HIV During the 2022 Mpox Outbreak : A Retrospective Cohort Study.

BACKGROUND: The recent mpox outbreak has disproportionately affected people with HIV (PWH) and resulted in the first widespread use of the novel antiviral tecovirimat. Whether treatment outcomes differ between PWH and those without HIV is unknown. OBJECTIVE: To compare the clinical presentation and treatment outcomes of PWH and HIV-negative persons with mpox virus (MPXV) infection treated with tecovirimat. DESIGN: Retrospective cohort study of patients treated with tecovirimat for confirmed MPXV infection from June to August 2022. SETTING: Two academic medical centers in New York City. PARTICIPANTS: The study included 196 persons treated with tecovirimat from 20 June to 29 August 2022. Of 154 testing positive for MPXV, 72 were PWH and 4 had a CD4 count lower than 0.20 × 109 cells/L. MEASUREMENTS: Patient demographic characteristics, clinical presentation, treatment outcomes, and safety data for tecovirimat. RESULTS: Indications for tecovirimat treatment were similar between the PWH and HIV-negative groups. Four participants had serious adverse events; none were attributed to tecovirimat. Three of these 4 participants had HIV infection, and 2 had CD4 counts less than 0.20 × 109 cells/L. Twenty-two percent of participants had nonsevere adverse effects. Groups had similar rates of hospitalization, indications for treatment, and co-occurring infections, but PWH had fewer days from symptom onset to treatment (7.5 vs. 10). There was no difference in treatment outcomes, including days to improvement or rate of persistent symptoms. LIMITATION: Patients with mpox who were not treated with tecovirimat were not followed routinely and therefore lacked comparable outcome data, limiting evaluation of efficacy. CONCLUSION: In our cohort of patients treated with tecovirimat for severe mpox, HIV status did not seem to affect treatment outcomes. PRIMARY FUNDING SOURCE: National Institutes of Health.

Effect of Participative Web-Based Educational Modules on HIV and Sexually Transmitted Infection Prevention Competency Among Medical Students: Single-Arm Interventional Study.

BACKGROUND: The number of new HIV diagnoses in the United States continues to slowly decline; yet, transgender women and men who have sex with men remain disproportionately affected. Key to improving the quality of prevention services are providers who are comfortable broaching the subjects of sexual health and HIV prevention with people across the spectrum of gender identities and sexual orientations. Preservice training is a critical point to establish HIV prevention and sexual health education practices before providers' practice habits are established. OBJECTIVE: The study aimed to develop participative web-based educational modules and test their impact on HIV prevention knowledge and awareness in future providers. METHODS: Sexual health providers at an academic hospital, research clinicians, community engagement professionals, and New York City community members were consulted to develop 7 web-based educational modules, which were then piloted among medical students. We assessed knowledge of HIV and sexually transmitted infection prevention and comfort assessing the prevention needs of various patients via web-based questionnaires administered before and after our educational intervention. We conducted exploratory factor analysis of the items in the questionnaire. RESULTS: Pre- and postmodule surveys were completed by 125 students and 89 students, respectively, from all 4 years of training. Before the intervention, the majority of students had heard of HIV pre-exposure prophylaxis (122/123, 99.2%) and postexposure prophylaxis (114/123, 92.7%). Before the training, 30.9% (38/123) of the students agreed that they could confidently identify a patient who is a candidate for pre-exposure prophylaxis or postexposure prophylaxis; this increased to 91% (81/89) after the intervention. CONCLUSIONS: Our findings highlight a need for increased HIV and sexually transmitted infection prevention training in medical school curricula to enable future providers to identify and care for diverse at-risk populations. Participative web-based modules offer an effective way to teach these concepts.

Staphylococcus epidermidis Protection Against Staphylococcus aureus Colonization in People Living With Human Immunodeficiency Virus in an Inner-City Outpatient Population: A Cross-Sectional Study.

BACKGROUND: People living with human immunodeficiency virus (PLWH) have been disproportionally affected by methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection, in particular by clones USA300 and USA500. However, the contribution of epidemiological, bacterial, and immunological risk factors to the excess of S aureus in PLWH remain incompletely understood. METHODS: In this cross-sectional study, we determined the prevalence and molecular epidemiology of S aureus colonization in 93 PLWH attending an urban human immunodeficiency virus (HIV) clinic. Participants completed a structured interview assessing demographic information and risk factors for MRSA. Swabs were obtained from the nose, throat, and groin and cultured for S aureus and Staphylococcus epidermidis. RESULTS: Most participants had well controlled HIV infection (89, 96% CD4 >200). Thirty-six (39%) individuals were colonized with S aureus at 1 or more body sites, including 6 (6%) with MRSA. Regular gym use was a risk factor for S aureus but not MRSA carriage. In contrast, S epidermidis was present in almost all individuals (n = 84, 90%), predominantly in the nares (n = 66, 71%). Using generalized estimating equation models, we observed that the odds of S aureus colonization were significantly and drastically reduced when S epidermidis was detected (P = .0001). After controlling for site, gender, and age, we identified that the odds of S aureus colonization were 80% less if S epidermidis was present (adjusted odds ratio, 0.20; 95% confidence interval, .09-.45; P < .0001). CONCLUSIONS: Taken together, we observed a lower prevalence of S aureus and MRSA colonization than has been previously reported in PLWH. In this cohort, colonization with S epidermidis was protective against S aureus colonization.
