Improvement in health-related quality of life (HRQoL) is frequently reported as a potential benefit of treatment with direct acting antivirals (DAA) in patients with chronic hepatitis C virus (HCV) infection . Thereby, most of the available data were obtained from clinical trials that might have limited generalizability . Moreover, median increase of HRQoL does not necessarily reflect a clinical relevant change in all patients . This study aimed to investigate the impact of DAA therapy on the likelihood for clinically important improvements of HRQoL in a real-world setting.
Methods: Short-Form 36 (SF-36) data were completed between Feb 1, 2014 and Feb 9, 2018 by participants of the DHC-R (German- Hepatitis C-Registry), a national real-world cohort of over 15,500 HCV infected patients . SF-36 levels at week 12 to 24 (FU12/24) after end of treatment were compared to baseline (BL) levels . Minimal clinically important difference in mental and physical component summary scales (MCS and PCS) was defined as an increase of ≥2.5. Potential predictors (e.g. age, comorbidities, sex) of HRQoL changes were analyzed using a multivariate linear regression model .
Results: A total of 1,180 patients were analyzed, of whom 1,153 (97 .7%) achieved sustained virological response after DAA therapy . Overall, a statistically significant increase in HRQoL was documented for PCS (mean increase=2; p<0 .001) and MCS (mean increase=5; p<0 .001) affecting 62% and 68% of patients, respectively . This improvement was robust among various subgroups of patients including those with active drug usage as well as opioid substitution therapy . However, 59% and 43% of all patients failed to achieve a clinically important improvement (≥2.5) in MCS and PCS. Patients with lower MCS and PCS levels at BL had the highest chances for a clinically important increase in MCS (p=0 .022) and PCS (p<0 .001) after DAA therapy . Within the subgroup of low MCS scores at BL a BMI >30 kg/m2 (p=0 .034) and no SVR (p=0 .005) were identified as independent risk factors for failing to gain a clinically important increase of MCS. Age ≥65years (p=0.001) and depression (p=0 .010) were associated with no clinically important improvement of PCS.
Conclusion: DAA treatment is associated with an improvement of HRQoL in patients with chronic HCV infection . Patients with low MCS or PCS baseline values benefit most from DAA treatment. Nevertheless, roughly half of the patients fail to achieve a clinically important improvement . Figure: Proportion of patients with changes in SF-36 MCS and PCS at FU12/24 after DAA therapy .
