The Impact of Achieving Sustained Viral Response with Direct Antiviral Agents in in HCV/HIV Co-infected Patients.

BACKGROUND

Co-infection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) affects approximately 2.2 million people globally and is associated with accelerated liver disease progression, increased morbidity, and reduced quality of life (QoL). While direct-acting antivirals (DAAs) have revolutionized HCV treatment with high cure rates, evidence of their long-term impact on liver-related QoL and associated metabolic or immunologic shifts in HIV/HCV co-infected populations remains limited.

OBJECTIVES

To evaluate the effect of achieving sustained virologic response (SVR) with DAAs on long-term QoL in HIV/HCV co-infected patients and to examine associated changes in CD4 count, kidney function, and glucose levels.

METHODS

This retrospective observational study was conducted at the Rambam Health Care Campus, between 2015 and 2019. We collected demographic, clinical, and laboratory data from all patients with HIV/HCV co-infection. QoL was evaluated for at least 6 months after the end of treatment. Metabolic variables were collected before and after treatment to test the effects of treatment.

RESULTS

All 70 patients in the cohort achieved SVR. Successful treatment with DAAs resulted in a significant decrease in liver enzymes and globulin levels, and a substantial increase in CD4. A significant improvement in QoL after treatment was noticed in both sexes, regardless of liver fibrosis stage. FIB-4 calculations 6 months and 1 year after the end of therapy showed improved fibrosis levels after SVR.

CONCLUSIONS

The use of DAAs in HCV/HIV co-infected patients has improved the long-term QoL, metabolic factors, and fibrosis stage.
