Comparative outcomes of direct-acting antiviral treatment in patients with HIV-Hepatitis C co-infection: insights from a single center experience in Colombia. LE INFEZIONI IN MEDICINA 2023; 31:374-383. [PMID: 37701377 PMCID: PMC10495049 DOI: 10.53854/liim-3103-11] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 07/26/2023] [Indexed: 09/14/2023]
Abstract
Background Direct-acting antivirals (DAA) were introduced to Latin America with the aim of eliminating hepatitis C (HCV) in the region. There are scarce data on the outcomes of people living with HIV and HCV treated with these medications in Colombia. This study compares the outcomes of patients with HIV-HCV co-infection and HCV mono-infection treated with DAAs. Methods Retrospective observational study including patients ≥18 years old with HCV infection treated with DAAs from August 2017 to December 2019 in a comprehensive center in Colombia. The main outcome was sustained virologic response (SVR). Secondary outcomes included reinfection, relapse and adverse events. Results We included 223 individuals with HCV treated with DAAs; 142 (63.6%) individuals were mono-infected and 81 (36.3%) co-infected. Genotypes 1b (49.7%) and 4 (33.9%) were the most common. Overall SVR after DAA treatment was 96.8%. Relapse rate was 2.24%, reinfection rate was 6.28% and adverse events occurred in 27.8% of cases. SVR was comparable in patients with co- and mono-infection (95% vs 97.8%, p=0.245). Conclusion DAA were effective in mono-infected (HCV) and co-infected (HCV/HIV) patients and reinfection was high in this last group.

Hepatitis C Virus Micro-elimination Among People With HIV in San Diego: Are We on Track? Open Forum Infect Dis 2023; 10:ofad153. [PMID: 37065984 PMCID: PMC10099471 DOI: 10.1093/ofid/ofad153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 03/20/2023] [Indexed: 04/18/2023] Open
Abstract
Background Rising incidence of hepatitis C virus (HCV) among people with HIV (PWH) in San Diego County (SDC) was reported. In 2018, the University of California San Diego (UCSD) launched a micro-elimination initiative among PWH, and in 2020 SDC launched an initiative to reduce HCV incidence by 80% across 2015-2030. We model the impact of observed treatment scale-up on HCV micro-elimination among PWH in SDC. Methods A model of HCV transmission among people who inject drugs (PWID) and men who have sex with men (MSM) was calibrated to SDC. The model was additionally stratified by age, gender, and HIV status. The model was calibrated to HCV viremia prevalence among PWH in 2010, 2018, and 2021 (42.1%, 18.5%, and 8.5%, respectively), and HCV seroprevalence among PWID aged 18-39 years, MSM, and MSM with HIV in 2015. We simulate treatment among PWH, weighted by UCSD Owen Clinic (reaching 26% of HCV-infected PWH) and non-UCSD treatment, calibrated to achieve the observed HCV viremia prevalence. We simulated HCV incidence with observed and further treatment scale-up (+/- risk reductions) among PWH. Results Observed treatment scale-up from 2018 to 2021 will reduce HCV incidence among PWH in SDC from a mean of 429 infections/year in 2015 to 159 infections/year in 2030. County-wide scale-up to the maximum treatment rate achieved at UCSD Owen Clinic (in 2021) will reduce incidence by 69%, missing the 80% incidence reduction target by 2030 unless accompanied by behavioral risk reductions. Conclusions As SDC progresses toward HCV micro-elimination among PWH, a comprehensive treatment and risk reduction approach is necessary to reach 2030 targets.

Syphilis testing and diagnosis among people with HIV engaged in care at four United States clinical sites, 2014-2018. Clin Infect Dis 2021; 75:483-492. [PMID: 34788808 DOI: 10.1093/cid/ciab944] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Despite rising rates of syphilis among people with HIV (PWH) in the United States, there is no optimal syphilis screening frequency or prioritization. METHODS We reviewed records of all PWH in care between January 1, 2014 and November 16, 2018 from four sites in the CFAR Network of Integrated Clinical Systems Cohort (CNICS; N=8455). We calculated rates of syphilis testing and incident syphilis and used Cox proportional hazards models modified for recurrent events to examine demographic and clinical predictors of testing and diagnosis. RESULTS Participants contributed 29568 person-years of follow-up. The rate of syphilis testing was 118 tests per 100 person-years (95%CI: 117-119). The rate of incident syphilis was 4.7 cases per 100 person-years (95%CI: 4.5-5.0). Syphilis diagnosis rates were highest among younger cisgender MSM and transgender women, Hispanic individuals, people who inject drugs, and those with detectable HIV RNA, rectal infections, and hepatitis C. CONCLUSION We identified PWH who may benefit from more frequent syphilis testing and interventions for syphilis prevention.
