Effect of Direct-acting Antivirals Treatment on Renal Function Among HCV-infected Patients / 中山大学学报(医学科学版)

ABSTRACT

； ObjectiveTo explore the effect of direct-acting antiviral treatment on renal function in patients with chronic hepatitis C. MethodsA total of 123 HCV-infected patients receiving DAAs treatment at the Third Affiliated Hospital of Sun Yat-sen University from January 2017 to December 2021 were included in this study. To explore the renal function in patients with chronic hepatitis C treated with direct-acting antivirals， serum creatinine values were collected before， during and after the treatment， which were used to estimate the eGFR by the MDRD equation to assess the changes in renal function. ResultsOf the 123 patients enrolled， 67.5%（n=83）were male， and the mean age of participants was （50±11） years old. The mean follow-up period was 24 weeks . Comorbidities included cirrhosis in 26.8%， and diabetes in 10.6%. Meanwhile， 11.4% of the cohort had eGFR < 60 mL/（min ·1.73 m2）， 33.3% of the cohort had eGFR 60 to 90 mL/（min ·1.73 m2）， and 55.3% had eGFR≥90 mL/（min ·1.73 m2）. No decrease in renal function was seen among all the HCV-infected patients at the end of treatment or the follow-up period after treatment. However， compared with the eGFR at the baseline， eGFR in CKD2 patients in the follow-up period was improved 【（88.65±15.52） mL/（min ·1.73 m2）vs （78.12 ±7.60） mL/（min ·1.73 m2）， P< 0.001】. And 14.6% （n=18） of patients experienced progressive deterioration of renal function. Logistic regression analysis showed that diabetes could predict the deterioration of renal function （OR=4.663， P=0.016）. ConclusionsOur study shows renal function is not impair among HCV-infected patients following DAAs treatment， and renal function in CKD2 patients have improvements. However， HCV-infected patients with diabetes mellitus are at a high risk of renal impairment and closely monitoring of renal function is still needed.
