Polysubstance Use and Related Risk Behaviors among People Who Inject Drugs in Kenya Preparing for Hepatitis C Virus Treatment. Viruses 2024; 16:1277. [PMID: 39205251 PMCID: PMC11359571 DOI: 10.3390/v16081277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Revised: 08/07/2024] [Accepted: 08/09/2024] [Indexed: 09/04/2024] Open
Abstract
Polysubstance use (PSU), injection drug use (IDU), and equipment sharing are associated with bloodborne infection (BBI) transmission risk, particularly Hepatitis C Virus (HCV), yet data on PSU in low- and middle-income countries (LMICs) is limited. We report on baseline PSU, medication-assisted treatment (MAT) engagement, and motivation to reduce IDU among 95 people who inject drugs (PWID) who accessed needle and syringe programs (NSP) in Nairobi and Coastal Kenya prior to HCV treatment. Bivariate and multivariate logistic regression were used to examine the associations between PSU and behaviors that confer HCV transmission and acquisition risks. Most participants (70.5%) reported PSU in the last 30 days, and one-third (35.8%) reported PSU exclusive to just heroin and cannabis use. Common combinations were heroin and cannabis (49.3%), and heroin, cannabis, and bugizi (flunitrazepam) (29.9%). Participants at baseline were receiving MAT (69.5%), already stopped or reduced IDU (30.5%), and were HIV-positive (40%). PSU was significantly associated with IDU (p = 0.008) and the number of times (p = 0.016) and days (p = 0.007) injected in the last 30 days. Participants reported high PSU and equipment sharing, despite high MAT engagement. While co-locating BBI treatment within existing harm reduction services is necessary to promote uptake and curb re-infection, tailored services may be needed to address PSU, particularly in LMICs.

HCV-HIV co-infection in people who inject drugs: Barriers to treatment and cure of HCV infection in the era of DAAs, a prospective study in Athens, Greece. HIV Med 2024.

Abstract
OBJECTIVES HIV/hepatitis C virus (HCV) co-infection among people who inject drugs (PWID) remains a global health problem. The goal of our study was to evaluate, in a real-world setting, success rates of sustained virological response (SVR) using direct-acting antivirals (DAAs) to treat a population of PWID living with HCV/HIV. METHODS This was a prospective single-center observational study. We collected demographic, socioeconomic, and clinical data pertaining to HIV and HCV infection in PWID with several barriers to care. We identified risk factors for SVR failure. RESULTS Among 130 individuals retained to HIV care, we planned HCV treatment in 119/130 (91.5%); 106/119 (89.1%) started treatment with DAAs and 100/106 (94.3%) completed treatment. People not starting treatment were more often in active opioid drug use (odds ratio [OR] 0.25; 95% confidence interval [CI] 0.07-0.97, p = 0.045) and benzodiazepine abuse (OR 0.25; 95% CI 0.07-0.95, p = 0.042). Only 86/100 (86%) were tested for SVR at 12 weeks (SVR12) and 72/86 (83.7%) achieved SVR. PWID in opioid substitution programmes tended to return for SVR12 testing more often (54.7% vs. 30%, p = 0.081). Individuals in active opioid drug use (OR 0.226; 95% CI 0.064-0.793, p = 0.02) or with poor adherence (OR 0.187; 95% CI 0.043-0.814, p = 0.025) were less likely to achieve SVR. At the end of our study period, 113/119 (95%) treatment-eligible patients remained alive. HCV infection was cured in 68/113 (61.1%) people. CONCLUSIONS Our findings underscore the importance of prioritizing combatting substance use to achieve HCV elimination goals. A systematic approach with effort to overcome barriers to receiving and completing treatment and encourage to enrol in opioid substitution programmes if not possible to completely abstain from use, can help increase chances of HCV cure.

A community-based strategy to eliminate hepatitis C among people who inject drugs in Vietnam. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 37:100801. [PMID: 37693880 PMCID: PMC10485672 DOI: 10.1016/j.lanwpc.2023.100801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 02/27/2023] [Accepted: 05/10/2023] [Indexed: 09/12/2023]
Abstract
Background Towards hepatitis C elimination among people who inject drugs (PWID), we assessed the effectiveness of a strategy consisting of a community-based respondent-driven sampling (RDS) as wide screening, a simplified and integrated hospital-based care, and prevention of reinfection supported by community-based organisations (CBO), in Hai Phong, Vietnam. Methods Adults who injected heroin were enrolled in a RDS survey implemented in two CBO premises. Rapid HIV and HCV tests were done on site, and blood was taken for HCV RNA testing. Those with detectable HCV RNA were referred with CBO support to three public hospitals for 12-week sofosbuvir/daclatasvir, plus ribavirin for patients with cirrhosis. Participants were followed-up 12 weeks post-treatment (SVR12) and 48 weeks after enrolment. The primary endpoint was the rate of undetectable HCV RNA participants at 48 weeks. Findings Among the 1444 RDS survey participants, 875 had hepatitis C. Their median age was 41 years (IQR 36-47), 96% were males, 36% were HIV-coinfected. Overall, 686 (78.4%) started sofosbuvir/daclatasvirs, and 629 of the 647 (97.2%) patients tested at SVR12 were cured. At week 48 (581/608) 95.6% had undetectable HCV RNA, representing 66.4% of all PWID identified with hepatitis C. The reinfection rate after SVR12 was 4/100 person-years (95% CI: 2-7). Interpretation Our strategy, involving CBO and addressing all steps from wide HCV screening to prevention of reinfection, stands as a promising approach to eliminate HCV among PWID in low and middle-income countries. Funding France ANRS|MIE (#ANRS12380). The RDS survey was implemented with grants from the NIDA (#R01DA041978) and ANRS|MIE (#ANRS12353).

Predictors of hepatitis C cure among people who inject drugs treated with directly observed therapy supported by peer case managers in Kenya. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 113:103959. [PMID: 36758335 PMCID: PMC10034760 DOI: 10.1016/j.drugpo.2023.103959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 01/12/2023] [Accepted: 01/19/2023] [Indexed: 02/10/2023]
Abstract
BACKGROUND & AIMS Directly observed therapy (DOT) maximizes adherence and minimizes treatment gaps. Peer case managers (PCM) have also shown promise as a component of integrated HCV treatment strategies. DOT and PCM-support have been underexplored, particularly in low- and middle-income countries (LMICs). The objective of this study was to evaluate predictors of sustained virologic response (SVR) among people who inject drugs (PWID) attending medication-assisted treatment (MAT) and needle and syringe programs (NSP) sites in Kenya. METHODS We recruited PWID accessing MAT and NSP in Nairobi and Coastal Kenya. PWID were treated with ledipasvir/sofosbuvir using DOT supported by PCMs. We used bivariate and multivariate logistic regression to examine the impact of sociodemographic, behavioral, and clinical factors on SVR. RESULTS Among 92 PWID who initiated HCV treatment, 79 (86%) were male with mean age of 36.3 years (SD=±6.5); 38 (41%) were HIV-positive, and 87 (95%) reported injecting drugs in the last 30 days. Just over half of participants were genotype 1a (55%), followed by genotype 4a (41%) and mixed 1a/4a (3%). Most participants, 85 (92%) completed treatment and 79 (86%) achieved SVR. While sociodemographic and behavioral factors including recent injection drug use were not significantly associated with achieving SVR, being fully adherent (p=0.042), number of doses taken (p=0.008) and treatment completion (p= 0.001) were associated with higher odds of achieving SVR. CONCLUSIONS DOT with PCM-support was an effective model for HCV treatment among PWID in this LMIC setting. Adherence was the most important driver of SVR suggesting DOT and PCM support can overcome other factors that might limit adherence. Further research is necessary to ascertain the effectiveness of other models of HCV care for PWID in LMICs given NSP and MAT access is variable, and DOT may not be sustainable with limited resources.

Challenges and best practices for hepatitis C care among people who inject drugs in resource limited settings: focus group discussions with healthcare providers in Kenya. Glob Public Health 2022; 17:3627-3637. [PMID: 35941717 PMCID: PMC9898079 DOI: 10.1080/17441692.2022.2110919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 08/02/2022] [Indexed: 02/06/2023]
Abstract
People who inject drugs (PWID) living with Hepatitis C (HCV) in low- and middle-income countries face substantial barriers to HCV care. We sought to gain healthcare providers' perspectives on challenges and best practices for HCV care provision among PWID in Kenya. We conducted three focus group discussions (FGD) with 23 healthcare providers working with PWID living with HCV in Nairobi and Mombasa. Transcribed interviews were analysed thematically. Overarching themes regarding HCV prevention and treatment were: (1) lack of HCV-related knowledge at the provider and patient levels; (2) stigmatisation of people living with HCV and PWID; and (3) difficulties among PWID with navigating the healthcare system. Some providers suggested systematically integrating HCV care into existing PWID-specific harm reduction programs to improve HCV care provision as well as creating national HCV guidelines to guide clinicians. This study highlights the need for national HCV treatment guidelines and increased public HCV education, as well as culturally sensitive models integrating HCV care into programs PWID are already accessing. These strategies will be useful in improving access to HCV care among PWID and has the potential to decrease HCV transmission and prevalence among this vulnerable population.

Abstract
OBJECTIVES People who inject drugs (PWID) in Kenya have high HIV (range across settings: 14-26%) and hepatitis C virus (HCV; 11-36%) prevalence. We evaluated the impact of existing and scaled-up interventions on HIV and HCV incidence among PWID in Kenya. DESIGN HIV and HCV transmission model among PWID, calibrated to Nairobi and Kenya's Coastal region. METHODS For each setting, we projected the impact (percent of HIV/HCV infections averted in 2020) of existing coverages of antiretroviral therapy (ART; 63-79%), opioid agonist therapy (OAT; 8-13%) and needle and syringe programmes (NSP; 45-61%). We then projected the impact (reduction in HIV/HCV incidence over 2021-2030), of scaling-up harm reduction [Full harm reduction ('Full HR'): 50% OAT, 75% NSP] and/or HIV (UNAIDS 90-90-90) and HCV treatment (1000 PWID over 2021-2025) and reducing sexual risk (by 25/50/75%). We estimated HCV treatment levels needed to reduce HCV incidence by 90% by 2030. RESULTS In 2020, OAT and NSP averted 46.0-50.8% (range of medians) of HIV infections and 50.0-66.1% of HCV infections, mostly because of NSP. ART only averted 12.9-39.8% of HIV infections because of suboptimal viral suppression (28-48%). Full HR and ART could reduce HIV incidence by 51.5-64% and HCV incidence by 84.6-86.6% by 2030. Also halving sexual risk could reduce HIV incidence by 68.0-74.1%. Alongside full HR, treating 2244 PWID over 2021-2025 could reduce HCV incidence by 90% by 2030. CONCLUSION Existing interventions are having substantial impact on HIV and HCV transmission in Kenya. However, to eliminate HIV and HCV, further scale-up is needed with reductions in sexual risk and HCV treatment.
