Abstract

Summary: Guidelines recommend evaluating persistent alteration of liver tests in HCV‐infected patients after sustained virological response (SVR) and its influence on liver disease progression. We studied the prevalence, etiology, associated factors and evolutionary implications of persistent alteration of liver tests in HCV patients after direct‐acting antivirals (DAA)‐induced SVR. This was a prospective study of HCV‐infected patients and SVR after DAA. Those with another previously diagnosed liver disease were excluded. Persistent alteration of liver tests was defined as any increase in ALT, AST or GGT at SVR12 and SVR24. Causes were determined according to standard clinical practice, including liver biopsy and follow‐up transient elastography. A total of 1112 patients were included (70.8% males, median age 53 years, 38.8% cirrhosis, 34.9% interferon‐experienced, 56.8% HIV‐coinfected). Persistent alteration of liver tests was detected in 130/1112 patients (11.7% [95%CI: 9.7‐13.6]). Its frequency differed between HCV‐monoinfected (45/480: 9.4% [95%CI: 6.7‐12.1]) and HIV‐coinfected (85/632: 13.5% [95%CI: 10.7‐16.2]) ( P = .046). In multivariable analysis, cirrhosis (OR 2.12; 95%CI: 1.28‐3.53; P = .004) and baseline transient elastography values (OR 1.03; 95%CI: 1.01‐1.04; P = .000) were associated with persistent alteration of liver tests. The main etiologies were clinical diagnosis suggestive of nonalcoholic fatty liver disease in 47 (36.2%), alcohol in 30 (23.1%) and drug consumption in 19 (14.6%). Baseline and follow‐up transient elastography was performed in 594 patients and showed a significantly different decrease in patients who did or did not have a persistent alteration of liver tests (−21.1% vs −30%, respectively; P = .003), independently of sex, HIV status or baseline TE value. In conclusion, persistent alteration of liver tests is not infrequent after SVR. It is associated with cirrhosis and baseline transient elastography, and the main cause is fatty liver. According to transient elastography changes, persistent alteration of liver tests seems to affect the course of liver disease.
