BackgroundPersons with HIV (PWH) with persistently low CD4 counts despite efficacious antiretroviral therapy could have higher hospitalization risk.MethodsIn six US and Canadian clinical cohorts, PWH with virologic suppression for ≥1 year in 2005-2015 were followed until virologic failure, loss to follow-up, death, or study end. Stratified by early (Years 2-5) and long-term (Years 6-11) suppression and lowest pre-suppression CD4 count 500 cells/μL had an aIRR of 1.44 during early suppression (95% CI 1.01-2.06), and 1.67 (1.03-2.72) during long-term suppression. Among patients with lowest pre-suppression CD4 ≥200 (56%), patients with current CD4 351-500 versus >500 cells/μL had an aIRR of 1.22 (0.93-1.60) during early suppression and 2.09 (1.18-3.70) during long-term suppression.ConclusionsVirologically suppressed patients with lower CD4 counts experienced higher hospitalization rates, and could potentially benefit from targeted clinical management strategies.

BackgroundTo assess the possible impact of antiretroviral therapy improvements, aging, and comorbidities, we examined trends in all-cause and cause-specific hospitalization rates among persons with HIV (PWH) from 2005 to 2015.MethodsIn 6 clinical cohorts, we followed PWH in care (≥1 outpatient CD4 count or HIV load [VL] every 12 months) and categorized ICD codes of primary discharge diagnoses using modified Clinical Classifications Software. Poisson regression estimated hospitalization rate ratios for calendar time trends, adjusted for demographics, HIV risk factor, and annually updated age, CD4, and VL.ResultsAmong 28 057 patients (125 724 person-years), from 2005 to 2015, the median CD4 increased from 389 to 580 cells/µL and virologic suppression from 55% to 85% of patients. Unadjusted all-cause hospitalization rates decreased from 22.3 per 100 person-years in 2005 (95% confidence interval [CI], 20.6-24.1) to 13.0 in 2015 (95% CI, 12.2-14.0). Unadjusted rates decreased for almost all diagnostic categories. Adjusted rates decreased for all-cause, cardiovascular, and AIDS-defining conditions, increased for non-AIDS-defining infection, and were stable for most other categories.ConclusionsAmong PWH with increasing CD4 counts and viral suppression, unadjusted hospitalization rates decreased for all-cause and most cause-specific hospitalizations, despite the potential effects of aging, comorbidities, and cumulative exposure to HIV and antiretrovirals.

Background In the Southeastern United States, the 2022 mpox outbreak disproportionately impacted people who are black and people with HIV (PWH). Methods We analyzed a cohort of 395 individuals diagnosed with mpox across 3 health care systems in Atlanta, Georgia between 1 June 2022 and 7 October 2022. We present demographic and clinical characteristics and use multivariable logistic regression analyses to evaluate the association between HIV status and severe mpox (per the US Centers for Disease Control and Prevention definition) and, among PWH, the associations between CD4+ T-cell count and HIV load with severe mpox. Results Of 395 people diagnosed with mpox, 384 (97.2%) were cisgender men, 335 (84.8%) identified as black, and 324 (82.0%) were PWH. Of 257 PWH with a known HIV load, 90 (35.0%) had > 200 copies/mL. Severe mpox occurred in 77 (19.5%) individuals and there was 1 (0.3%) death. Tecovirimat was prescribed to 112 (28.4%) people, including 56 (72.7%) people with severe mpox. In the multivariable analysis of the total population, PWH had 2.52 times higher odds of severe mpox (95% confidence interval [CI], 1.01–6.27) compared with people without HIV. In the multivariable analysis of PWH, individuals with HIV load > 200 copies/mL had 2.10 (95% CI, 1.00–4.39) times higher odds of severe mpox than PWH who were virologically suppressed. Lower CD4+ T-cell count showed a significant univariate association with severe mpox but was not found to be significantly associated with severe mpox in multivariable analysis. Conclusions PWH with nonsuppressed HIV loads had more mpox complications, hospitalizations, and protracted disease courses than people without HIV or PWH with suppressed viral loads. PWH with nonsuppressed HIV loads who are diagnosed with mpox warrant particularly aggressive monitoring and treatment. [ABSTRACT FROM AUTHOR]

The 2022 mpox outbreak primarily involved sexual transmission among men who have sex with men and disproportionately affected persons with human immunodeficiency virus (HIV). We examined viral dynamics and clinical features in a cohort evaluated for mpox infection at a comprehensive HIV clinic in Atlanta, Georgia. Viral DNA was found in 8 oropharyngeal and 5 anorectal specimens among 10 mpox cases confirmed by lesion swab polymerase chain reaction. Within-participant anatomic site of lowest cycle threshold (Ct) value varied, and lower Ct values were found in oropharyngeal and anorectal swabs when corresponding symptoms were present. This provides insight into mpox infection across multiple anatomic sites among people with HIV. [ABSTRACT FROM AUTHOR]

Retention in HIV care and viral suppression rates remain suboptimal, especially among people with HIV (PWH) facing complex barriers to care such as mental health conditions, substance use disorders, and housing insecurity. The Center for Adherence, Retention, and Engagement Support (CARES) program utilizes an interdisciplinary team that delivers integrated services in a drop-in setting to provide individualized care to PWH with complex psychosocial needs. We describe the CARES program and evaluate its effectiveness in retaining patients in care to achieve virological suppression. We characterized 119 referrals of PWH experiencing homelessness, mental health conditions, and substance use disorders to CARES between 2011 and 2017, and collected data for a 24-month observation period through 2019. Outcomes of patients who participated in CARES were compared with those who were referred but did not participate. The primary outcome was viral suppression (<200 copies/mL) at least once during 2-year follow-up. Retention in care (≥2 completed medical visits ≥90 days apart in each year post-referral) was a secondary outcome. Of 119 PWH referred to CARES, 59 participated with ≥2 visits. Those who participated in CARES were more likely to achieve viral suppression [adjusted odds ratio (aOR) 3.50, 95% confidence interval (CI) 1.19–10.32] and to be retained in care (aOR 3.73, 95% CI 1.52–9.14) compared with those who were referred but did not participate. This analysis found that the CARES program improved retention in care and viral suppression among PWH with complex psychosocial needs and suggests that it may represent a useful model for future programming.

Background Persons with human immunodeficiency virus (PWH) may experience a cycle of engaging and disengaging in care referred to as "churn." While human immunodeficiency virus (HIV) churn is predicted to be more prevalent in the southern United States (US), it has not been well characterized in this region. Methods We conducted a retrospective cohort study involving PWH newly establishing care at a large urban clinic in Atlanta, Georgia, from 2012 to 2017, with follow-up data collected through 2019. The primary exposure was churn, defined as a ≥12-month gap between routine clinic visits or viral load (VL) measurements. We compared HIV metrics before and after churn and assessed the risk of future churn or loss to follow-up. Results Of 1303 PWH newly establishing care, 81.7% were male and 84.9% were Black; 200 (15.3%) experienced churn in 3.3 years of median follow-up time. The transmissible viremia (TV) rate increased from 28.6% prechurn to 66.2% postchurn (P <.0001). The 122 PWH having TV on reengagement had delayed time to subsequent viral suppression (adjusted hazard ratio, 0.59 [95% confidence interval {CI},.48–.73]), and PWH returning to care contributed disproportionately to the community viral load (CVL) (proportion of CVL/proportion of patients, 1.96). Churn was not associated with an increased risk of subsequent churn (adjusted odds ratio [aOR], 1.53 [95% CI,.79–2.97]) or loss to follow-up (aOR, 1.04 [95% CI,.60–1.79]). Conclusions The rate of churn in a southern US clinic was high, and those who experienced churn had increased TV at reentry and disproportionately contributed to the CVL and likely contributing to ongoing HIV transmission.

Background. Studies evaluating response to treatment with Highly Active Antiretroviral Therapy (HAART) fail to examine Haitian patients living in the U.S. as a distinct group. Methods. This study was designed to determine the effectiveness of HAART in Haitians compared with other minority groups. We conducted a retrospective cohort study of HIV patients from two clinics. The cohort included 96 Hispanics, 60 African Americans, and 49 Haitians, after reviewing a total of 891 charts. Results. At 96 weeks, fewer Haitians (58.5%) achieved a suppressed viral load than African American (74.1%) or Hispanic (82.8%) patients (p=.021). Median CD4 counts at baseline were lowest among Haitians, with 158 cells/mm3, compared with African Americans, 176 cells/mm3 and Hispanics, 199 cells/mm3. Conclusions. Haitians are not doing as well on HAART as other groups. This may be explained by linguistic, cultural, or other barriers that are not currently addressed by the health care system in the United States. [ABSTRACT FROM AUTHOR]

• Detection of mpox virus at mucosal sites will be critical in any future outbreak. • The Xpert® Mpox assay is one of two CLIA-waived assays with FDA EUA. • Oropharyngeal, anorectal and cutaneous lesion swabs were tested. • We included 20 patients with suspicion for cutaneous mpox, 10 were confirmed cases. • The Xpert® had 100 % positive agreement with our reference assay across sample types. • 5 of 5 oropharyngeal and 7 of 8 anorectal specimens spiked at 2x LOD were detected. Anorectal and oropharyngeal exposures are implicated in sexual transmission of mpox, but authorized assays in the United States are only validated with cutaneous lesion swabs. Diagnostic assays for anorectal and oropharyngeal swabs are needed to address potential future outbreaks. The Cepheid Xpert® Mpox is the first point-of-care assay to receive FDA emergency use authorization in the United States and would be a valuable tool for evaluating these sample types. Our exploratory study demonstrates 100 % positive agreement with our in-house PCR assay for natural positive anorectal and oropharyngeal specimens and 92 % sensitivity with low-positive spiked specimens. The Xpert® assay detected viral DNA in specimens not detected by our reference PCR assay from four participants with mpox DNA at other sites, suggesting it may be more sensitive at low viral loads. In conclusion, the validation of the Xpert® for oropharyngeal and anorectal sample types can be rapidly achieved if clinical need returns and prospective samples become available.
