Time from diagnosis to treatment in vulnerable populations versus general population: Do we testand-treat our HCV patients in the same way?

ABSTRACT

Background: Stigma and poor linkage to care, amplified in the setting of the COVID-19 pandemic, are significant barriers for treating hepatitis C (HCV) in vulnerable patients, reducing our ability to implement a rapid test and treat (TnT) strategy with minimal monitoring within a simple patient cascade, as currently available HCV therapies would allow us to do This real-world analysis evaluates our ability to implement this approach in both general (GP) and vulnerable (VP) populations Methods: HCV-infected patients from 32 clinical cohorts in 8 countries treated with sofosbuvir/ velpatasvir without a history of decompensation or prior NS5A-inhibitor exposure were included in this analysis The VP included prisoners, homeless patients and patients with mental disorders Time to treatment (TT) between the most recent HCV RNA measurement and treatment initiation was estimated based on available data Results: A total of 2449 patients were included, 937 in GP (58% males), 1512 (72% males) in VP (59% with mental disorders, 31% homeless, 10% imprisoned) Mean age [standard deviation] was 55 [14] and 50 [14] years in GP and VP respectively Genotype 3 was observed in 35% and 33% respectively, compensated cirrhosis confirmed in 20% and 18% of GP versus VP. The median TT [MTT, interquartile range] was 55 days [23- 107] in GP and 60 days [27-132] in VP The longest MTT of 66 days [32-134] was observed in patients with mental disorders MTT was 63 days [29-149] in prisoners and 27 days [13-71] among the homeless Only 13% of GP and 8% of VP were treated the same day of diagnosis, and 70% of GP and 63% of VP were treated within 3 months In patients with mental disorders only 4% were treated the same day of diagnosis Cure rates were high and consistent with previously reported cure rates Conclusion: MTT varies across HCV patient groups, from over 6 months to 1 day This analysis shows that a quick treatment start is possible, both in general population and in vulnerable populations, supporting the feasibility of a TnT approach in all populations New strategies should be considered to engage patients with mental disorders in this model of care more effectively.
