Background
HCV prevalence estimates among people who inject drugs (PWID) in
Ukraine is high (60%-90%), yet barriers to HCV treatment and
care remain substantial including limited access to direct acting antiviral
(DAA) medications. A feasibility scale-up project implemented HCV treatment
in community-based settings to improve access to DAA treatment for key
populations in this context.
Methods
Using program-level data and verified medical records, we describe
the development, implementation processes and outcomes for HCV treatment for
PWID and other risks groups. Most participants (76%) received a
combination of sofosbuvir, pegylated interferon, and ribavirin for 12 weeks.
Treatment enrollment started in June 2015; the first two waves are reported.
Data on demographics, HIV characteristics, HCV genotype and RNA levels,
including sustained virologic response (SVR) were obtained from verified
medical records. We used logistic regression to examine the independent
correlates of achieving a SVR.
Results
The project was implemented in 19 healthcare institutions from 16
regions of Ukraine, mainly within AIDS specialty centers. Our analytical
sample included 1,126 participants who were mostly men (73%) and the
majority were HIV co-infected (79%). Treatment retention was
97.7% and the proportion of participants who achieved SVR for the
1,029 (91%) with complete data was 94.3% (95% CI
92.8%â95.7%). PWID who were currently injecting had
comparable SVR rates (89.2%, 95% CI
81.5â94.5%) to PWID not injecting (94.4%,
95% CI 92.4â96.1), PWID on methadone (94.4%,
95%CI 92.4â96.1), and âotherâ risk group
(95.2%, 95% CI 91.3â97.7). Independent factors
associated with achieving a SVR were females sex (AOR: 3.44, 95% CI
1.45â8.14), HCV genotype 3 (AOR: 4.57, 95% CI 1.97 - 10.59)
compared to genotype 1. SVR rates in PWID actively injecting did not differ
significantly from any other group.
Conclusion
Both patient-level and structural factors influence HCV treatment
scale-up in Ukraine, but patient-level outcomes confirm high levels of
achieving SVR in PWID, irrespective of injection and treatment status.
