The article presents a study which examined the reported cases of laboratory-confirmed Monkeypox (mpox) virus infections in California to determine the mpox-associated hospitalization by JYNNEOS vaccination status. Also cited are the cases of hospitalization among people infected with human immunodeficiency virus (HIV), and the demographic characteristics of unvaccinated mpox patients.

High prevalences of HIV and other sexually transmitted infections (STIs) have been reported in the current global monkeypox outbreak, which has affected primarily gay, bisexual, and other men who have sex with men (MSM) (1-5). In previous monkeypox outbreaks in Nigeria, concurrent HIV infection was associated with poor monkeypox clinical outcomes (6,7). Monkeypox, HIV, and STI surveillance data from eight U.S. jurisdictions* were matched and analyzed to examine HIV and STI diagnoses among persons with monkeypox and assess differences in monkeypox clinical features according to HIV infection status. Among 1,969 persons with monkeypox during May 17-July 22, 2022, HIV prevalence was 38%, and 41% had received a diagnosis of one or more other reportable STIs in the preceding year. Among persons with monkeypox and diagnosed HIV infection, 94% had received HIV care in the preceding year, and 82% had an HIV viral load of <200 copies/mL, indicating HIV viral suppression. Compared with persons without HIV infection, a higher proportion of persons with HIV infection were hospitalized (8% versus 3%). Persons with HIV infection or STIs are disproportionately represented among persons with monkeypox. It is important that public health officials leverage systems for delivering HIV and STI care and prevention to reduce monkeypox incidence in this population. Consideration should be given to prioritizing persons with HIV infection and STIs for vaccination against monkeypox. HIV and STI screening and other recommended preventive care should be routinely offered to persons evaluated for monkeypox, with linkage to HIV care or HIV preexposure prophylaxis (PrEP) as appropriate.

Background: Given the challenges and costs associated with implementing HIV-1 incidence assay testing, there is great interest in evaluating the use of commercial HIV diagnostic tests for determining recent HIV infection. A diagnostic test with the capability of providing reliable data for the determination of recent HIV infection without substantial modifications to the test protocol would have a significant impact on HIV surveillance. The Abbott ARCHITECT HIV Ag/Ab Combo Assay is an antigen/antibody immunoassay, which meets the criteria as the first screening test in the recommended HIV laboratory diagnostic algorithm for the United States. Methods: In this study, we evaluated the performance characteristics of the ARCHITECT HIV Ag/Ab Combo signal-to-cutoff ratio (S/Co) for determining recent infection, including estimation of the mean duration of recent infection (MDRI) and false recent rate (FRR), and selection of recency cutoffs. Results: The MDRI estimates for the S/Co recency cutoff of 400 is within the 4 to 12 months range recommended for HIV incidence assays, and the FRR rate for this cutoff was 1.5%. Additionally, ARCHITECT Combo S/Co values were compared relative to diagnostic test results from two prior prospective HIV-1 diagnostic studies in order to validate the use of the S/Co for both diagnostic and recency determination. Conclusion: Dual-use of the ARCHITECT Combo assay data for diagnostic and incidence purposes would reduce the need for separate HIV incidence testing and allow for monitoring of recent infection for incidence estimation and other public health applications.

Background Infective endocarditis (IE) is a life-threatening bacterial infection of the heart valves, most often diagnosed in older persons and persons with prior cardiac surgery. It is also associated with injection drug use, a behavior that has increased in recent years along with the US opioid crisis. Methods We conducted a retrospective cohort analysis of commercial and Medicaid health insurance databases to estimate incident cases of IE in the United States in 2017, stratified by persons living with human immunodeficiency virus (HIV), hepatitis C virus (HCV), and opioid use disorder (OUD). We also estimated annual percentage changes (EAPCs) in IE from 2007–2017 among persons with commercial insurance. Results The weighted incidence rate of IE was 13.8 cases per 100 000 persons among persons with commercial insurance, and 78.7 among those with Medicaid. The incidence rate of IE among commercially insured persons increased slightly from 2007–2017 (EAPC, 1.0%). It decreased among commercially insured persons living with HIV, from 148.0 in 2007 to 112.1 in 2017 (EAPC, −4.3%), and increased among those with HCV infection, from 172.4 in 2007 to 238.6 in 2017 (EAPC, 3.2%). Among persons aged 18–29 years with HCV infection, IE increased from 322.3 in 2007 to 1007.1 in 2017 (EAPC, 16.3%), and among those with OUD it increased from 156.4 in 2007 to 642.9 in 2017 (EAPC, 14.8%). Conclusions The incidence rate of IE increased markedly among young persons with HCV infections or OUD. This increase appears to parallel the ongoing national opioid crisis. Harm reduction with syringe services programs, medications for opioid use disorder, and safe injection practices can prevent the spread of HIV, HCV, and IE. [ABSTRACT FROM AUTHOR]

Objectives. To describe and control an outbreak of HIV infection among people who inject drugs (PWID). Methods. The investigation included people diagnosed with HIV infection during 2015 to 2018 linked to 2 cities in northeastern Massachusetts epidemiologically or through molecular analysis. Field activities included qualitative interviews regarding service availability and HIV risk behaviors. Results. We identified 129 people meeting the case definition; 116 (90%) reported injection drug use. Molecular surveillance added 36 cases to the outbreak not otherwise linked. The 2 largest molecular groups contained 56 and 23 cases. Most interviewed PWID were homeless. Control measures, including enhanced field epidemiology, syringe services programming, and community outreach, resulted in a significant decline in new HIV diagnoses. Conclusions. We illustrate difficulties with identification and characterization of an outbreak of HIV infection among a population of PWID and the value of an intensive response. Public Health Implications. Responding to and preventing outbreaks requires ongoing surveillance, with timely detection of increases in HIV diagnoses, community partnerships, and coordinated services, all critical to achieving the goal of the national Ending the HIV Epidemic initiative.

In 2012, antiretroviral (ARV) treatment guidelines expanded indications and recommended antiretroviral treatment for all HIV-infected persons in the United States, regardless of CD4 cell count. This analysis describes ARV prescriptions among commercially insured HIV-infected adults from 2012 to 2014. We analyzed persons aged 18-64 years from 2012 to 2014 Truven Health MarketScan Commercial Claims and Encounters® database. We identified HIV-infected persons who had at least one inpatient or two outpatient medical claims and identified pharmacy claims using National Drug Codes. We calculated changes over time in ARV prescription and performed a multivariable regression analysis to examine differences in ARV prescriptions by age, sex, and geographic region. We identified 29,419 HIV-infected persons in 2012, 26,380 in 2013, and 25,414 in 2014. Overall percentage with ARV prescription increased by 7.3%. There was a 23% increase in ARV prescriptions among people new to care and a 6% increase among people already established in care. In 2014, more persons who were new to HIV care did not have an ARV prescription compared to persons established in HIV care (37.5% vs 19.3%, respectively; p  < 0.001). The percentage of persons without an ARV prescription was highest for persons residing in the Northeast (30.8%) compared to those residing in the West (21.7%), North Central (15.9%) and South (16.5%) and was higher among women (26.2%) compared to men (19.5%) (p < 0.001). Uptake of ARV medication has increased since the guidelines expanded their indications in 2012. Despite improvements from 2012 to 2014, a significant proportion of HIV-infected adults with a commercial health insurance plan were not prescribed ARV medications. Insurance-based strategies could be a novel method to increase the percentage of HIV-infected adults who receive optimal care in the United States. [ABSTRACT FROM AUTHOR]

Objectives: To estimate the number of men in the U.S. military who are gay, bisexual, or other men who have sex with men (MSM) to inform the development of military and other federal policies. Study design: We analyzed data from the National Surveys of Family Growth to estimate the number of U.S. men who were gay, bisexual, or MSM, and who had served in the military, compared to those who did not serve. We stratified using hierarchical categories of gay, bisexual, and other MSM to compare proportions in the military and general population. Results: We found that 4.23% of men self-reported as gay, bisexual, or other MSM among men who served in the military, compared to 4.14% among men who had not served (p = 0.93). When stratified, we found that 0.78% self-reported as gay among men who served in the military, compared to 2.12% among men who had not served (p<0.001). Conclusions: The proportion of men who identified as a gay was lower in the military than in the general population. This finding might have been influenced by historical military policies related to sexual orientation. [ABSTRACT FROM AUTHOR]
