Background: We previously demonstrated at the Ward 86 HIV clinic in San Francisco that long-acting cabotegravir/rilpivirine (LA-CAB/RPV) can rapidly lead to viral suppression (VS) in people with HIV (PWH) with viremia due to adherence challenges. We now evaluate VS durability in this population.

Methods: We conducted a retrospective cohort study of PWH who started LA-CAB/RPV with viremia (HIV RNA viral load [VL]≥50 copies/mL) before December 2022. Our primary outcome was VS (VL<50 copies/mL) with LA-CAB/RPV persistence (not discontinued or late by >14 days) at 48 weeks, using the closest VL to 48+/-8 weeks. We also describe viral failure (VF), defined as <2-log VL decline at 4 weeks or VL≥200 copies/mL after initial VS with emergent CAB- or RPV-associated resistance mutations; and overall 48-week VS including those switched to alternative ART.

Results: Fifty nine PWH initiated LA-CAB/RPV with viremia and were included in analysis; 49% had CD4<200 cells/µL and median baseline VL was 42,900 copies/mL (Q1-Q3 5,272-139,038). At 48 weeks, 47 met the primary outcome of VS with LA-CAB/RPV persistence (80%; 95%CI 67-89%). Five had VF with resistance (three with RPV-associated mutations, two with CAB and RPV-associated mutations) and one was lost-to-follow-up. At week 48, two of those with VF were suppressed on alternative regimens (lenacapavir+BIC/TAF/FTC and CAB+lenacapavir). Overall week 48 VS on either LA-CAB/RPV or alternative ART was 92% (54/59).

Conclusions: In PWH initiating LA-CAB/RPV with initial viremia, 48-week VS (<50 copies/mL) was 92%. Long-acting ART can be an important tool for improving VS among patients who face adherence challenges to oral ART.

Shortages of antimicrobial agents rank second among all pharmaceutical classes and are persistent and increasing. Underlying reasons for shortages include manufacturing and quality issues, market economics, and changes in demand. Antimicrobial shortages result in compromised outcomes, higher treatment costs, contribute to antibiotic resistance, and may lead to increased adverse effects.

This paper is part of a clinical practice guideline update on the risk assessment, diagnostic imaging, and microbiological evaluation of complicated intra-abdominal infections in adults, children, and pregnant people, developed by the Infectious Diseases Society of America. In this paper, the panel provides a recommendation for risk stratification according to severity of illness score. The panel's recommendation is based on evidence derived from systematic literature reviews and adheres to a standardized methodology for rating the certainty of evidence and strength of recommendation according to the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach.

This article is part of a clinical practice guideline update on the risk assessment, diagnostic imaging, and microbiological evaluation of complicated intraabdominal infections in adults, children, and pregnant people, developed by the Infectious Diseases Society of America. In this article, the panel provides recommendations for diagnostic imaging of suspected acute cholecystitis and acute cholangitis. The panel's recommendations are based on evidence derived from systematic literature reviews and adhere to a standardized methodology for rating the certainty of evidence and strength of recommendation according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.
