Nonalcoholic Fatty Liver Disease Risk Factors Affect Liver-Related Outcomes After Direct-Acting Antiviral Treatment for Hepatitis C.

ABSTRACT:

Introduction

In hepatitis C (HCV) patients, obesity and/or diabetes may increase the risk of liver-related outcomes. We aimed to determine whether diabetes and/or obesity are associated with adverse outcomes in direct-acting antiviral (DAA)-treated HCV patients.

Methods

We conducted a retrospective study of 33,003 HCV-infected, DAA-treated Veterans between 2013 and 2015. Body mass index was used to categorize patients into underweight (< 18.5 kg/m²), normal weight (18.5 to < 25 kg/m²), overweight (25 to < 30 kg/m²), obesity I (30 to < 35 kg/m²), and obesity II-III (> 35 kg/m²). Diabetes was defined by ICD-9/10 codes in association with hemoglobin A1c > 6.5% or medication prescriptions. Patients were followed from 180 days post-DAA initiation until 2/14/2019 to assess for development of cirrhosis, decompensations, hepatocellular carcinoma (HCC), and death. Multivariable Cox proportional hazards regression models were used to determine the association between diabetes and/or obesity and outcomes.

Results

During a mean follow-up of 3 years, 10.1% patients died, 5.0% were newly diagnosed with cirrhosis, 4.7% had a decompensation and 4.0% developed HCC. Diabetes was associated with an increased risk of mortality (AHR = 1.25, 95% CI 1.10-1.42), cirrhosis (AHR = 1.31, 95% CI 1.16-1.48), decompensation (AHR = 1.74, 95% CI 1.31-2.31), and HCC (AHR = 1.32, 95% CI 1.01-1.72) among patients without baseline cirrhosis. Compared to normal-weight persons, obese persons had a higher risk of cirrhosis, but overweight and obese persons had lower risk of mortality and HCC.

Conclusions

In this large DAA-treated Veterans cohort, pre-DAA diabetes increases mortality and liver-related events independent of SVR. Continued vigilance is warranted in patients with diabetes despite SVR. Elevated BMI categories appear to have improved outcomes, although further studies are needed to understand those associations.

Project description:Abstract Background and Aim The aim of this study was to identify the factors associated with liver‐related and non‐liver‐related mortality of patients with hepatitis C virus (HCV) after sustained virologic response (SVR) to direct‐acting antiviral agents (DAAs). Methods We conducted a retrospective, single‐center cohort study of HCV patients cured by DAAs. Results A total of 330 patients with SVR to DAAs were eligible. The median follow‐up period was 3.38 years (inter‐quartile range: 2.03–4.58). The cumulative liver‐related or non‐liver‐related mortality rates at 1, 3, and 5 years were 0.00 or 1.29%, 2.87 or 3.60%, and 5.10 or 9.46, respectively. Among the liver‐related deaths, 9 of the 10 were from liver cancer. Among the non‐liver‐related deaths, the most common cause was malignancy. Through multivariate analysis using the Cox proportional hazard model, diabetes mellitus (DM, hazard ratio 13.1, 95% confidence interval 2.81–61.3) and a history of hepatocellular carcinoma (HCC, 12.8, 2.76–59.2), independently predicted liver‐related death. No variables were associated with non‐liver‐related death. Conclusion Our findings suggest that DM and a history of HCC are risk factors for liver‐related mortality of HCV patients cured by DAAs. These results indicate that early management of HCV and HCC surveillance of diabetic patients after SVR are important to increase the chance of survival. Further studies are needed to confirm the association of DM and HCC history with survival. Very few studies have assessed the factors associated with liver‐related mortality in patients with sustained virologic response (SVR) following direct‐acting antiviral agents (DAA) treatment. The findings of our cohort study are that diabetes mellitus and a history of hepatocellular carcinoma (HCC) are risk factors for the liver‐related mortality of HCV patients cured by DAA. The results indicate that early management of HCV and HCC surveillance of diabetic patients after SVR are important to increase the chance of survival.
