Impact of direct-acting antiviral treatment of hepatitis C on the quality of life of adults in Ukraine.

BACKGROUND: Direct-acting antivirals (DAAs) are highly effective in achieving sustained virologic response among those with chronic hepatitis C virus (HCV) infection. Quality of life (QOL) benefits for an HCV-infected population with high numbers of people who inject drugs and people living with HIV (PLHIV) in Eastern Europe have not been explored. We estimated such benefits for Ukraine. METHODS: Using data from a demonstration study of 12-week DAA conducted in Kyiv, we compared self-reported QOL as captured with the MOS-SF20 at study entry and 12 weeks after treatment completion (week 24). We calculated domain scores for health perception, physical, role and social functioning, mental health and pain to at entry and week 24, stratified by HIV status. RESULTS: Among the 857 patients included in the final analysis, health perception was the domain that showed the largest change, with an improvement of 85.7% between entry and week 24. The improvement was larger among those who were HIV negative (104.4%) than among those living with HIV (69.9%). Other domains that showed significant and meaningful improvements were physical functioning, which improved from 80.5 (95% CI 78.9-82.1) at study entry to 89.4 (88.1-90.7) at 24 weeks, role functioning (64.5 [62.3-66.8] to 86.5 [84.9-88.2]), social functioning (74.2 [72.1-76.2] to 84.8 [83.2-86.5]) and bodily pain (70.1 [68.2-72.0] to 89.8 [88.5-91.1]). Across all domains, QOL improvements among PLHIV were more modest than among HIV-negative participants. CONCLUSION: QOL improved substantially across all domains between study entry and week 24. Changes over the study period were smaller among PLHIV.

Attitudes and potential barriers towards hepatitis C treatment in patients with and without HIV coinfection.

This study aimed to assess attitudes and potential barriers towards treatment in patients with hepatitis C virus (HCV) infection, comparing those with and without HIV coinfection. A cross-sectional survey of 82 HCV-infected adults with and without HIV was conducted in greater Los Angeles between November 2013 and July 2015. Overall, there were 53 (64.6%) with HIV coinfection, 20 (25.0%) with self-reported cirrhosis, and 22 (26.8%) with a history of prior HCV treatment. Of all, 93.2% wanted HCV treatment, but 45.9% were unwilling/unable to spend anything out of pocket, 29.4% were waiting for new therapies, and 23.5% were recommended to defer HCV treatment. HIV/HCV-coinfected patients were more likely to want treatment within one year (90.2% versus 68.2%, p = 0.02), more willing to join a clinical trial (74.5% versus 8.0%, p < 0.01), more willing to take medications twice daily (86.3% versus 61.5%, p = 0.01), and more likely to prefer hepatitis C treatment by an infectious diseases/HIV physician (36.7% versus 4.0%, p < 0.01). Of all, 77.1% of coinfected patients were willing to change antiretroviral therapy if necessary to treat HCV, but only 48.0% of patients were willing to take a medication if it had not been studied in HIV-positive patients. Treatment preferences differ between HIV/HCV-coinfected and HCV-monoinfected patients. Despite a strong willingness among the study cohort to start HCV treatment, other factors such as cost, access to medications, and provider reluctance may be delaying treatment initiation.

Performance of the Pooled Cohort atherosclerotic cardiovascular disease risk score in hepatitis C virus-infected persons.

Chronic hepatitis C virus (HCV) infection has been associated with an increased risk for cardiovascular disease (CVD). The recommended Pooled Cohort atherosclerotic cardiovascular disease (ASCVD) risk equation for estimation of 10-year CVD risk has not been validated in HCV-infected populations. We examined the performance of the ASCVD risk score in HCV-infected persons, using the national Electronically Retrieved Cohort of HCV Infected Veterans to derive a cohort of HCV-infected and uninfected subjects without baseline ASCVD, hepatitis B, or HIV infection, and with low-density lipoprotein cholesterol level<190 mg/dL. Performance of the ASCVD risk equation was assessed by Cox proportional hazard regression, C-statistics and Hosmer-Lemeshow statistic. The cohort included 70 490 HCV-infected and 97 766 HCV-uninfected men with mean age of 55 years, 56% White and 29% Black. Incident CVD event rates were similar between the two groups (13.2 and 13.4 events/1000 person-years), with a higher incidence of coronary heart disease events in the HCV-uninfected group and of stroke events in the HCV-infected group. Adjusting for ASCVD risk score, HCV infection was associated with higher risk for an ASCVD event in the subgroup with baseline ASCVD risk ≥7.5% (HR: 1.19, P<.0001). C-statistics were poor in both the HCV-infected and uninfected groups (0.60 and 0.61, respectively). By Hosmer-Lemeshow test, the ASCVD risk equation overestimated risk amongst lower risk patients and underestimated risk amongst higher risk patients in both the HCV-infected and uninfected groups. Further investigation is needed to determine whether a modified equation to accurately predict ASCVD risk in HCV-infected persons is warranted.
