Most liver tumours may be identified at early stages in cirrhotic patients treated with direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection, a study reports. Risk factors for increased risk of hepatocellular carcinoma following DAA therapy include male sex, diabetes and noninvasive markers of liver fibrosis.

Normal alanine aminotransferase protects against hepatic events in CHB patients

24 Sep 2018

In patients with chronic hepatitis B (CHB) infections on nucleos(t)ide analogue (NA) treatment, normal on-treatment alanine aminotransferase (ALT) levels are associated with lower risks of hepatic events, a recent study has shown.

Using data from the Clinical Data Analysis and Reporting System of Hong Kong, researchers evaluated serial on-treatment ALT levels of 21,182 CHB patients (mean age 51±13 years). ALT <30 and <19 U/L in males and females, respectively, were considered as normal. Composite hepatic events, including hepatocellular carcinoma, were the study outcomes.

Of the participants, 10,438 achieved normal on-treatment ALT levels within 12 months of NA treatment, while 10,745 did not. Only a minority (3.0 percent; n=627) of the patients developed the primary study outcome of composite hepatic events over a mean follow-up period of 4.0±1.7 years. Most of these were hepatocellular carcinoma (2.4 percent; n=509).

The cumulative hepatic event rates were lower in those with normal vs elevated on-treatment ALT at different time points: 3 months (4.27 percent vs 4.76 percent; p=0.083), 6 months (3.60 percent vs 5.24 percent; p<0.001), 9 months (3.44 percent vs 5.57 percent; p<0.001) and 12 months (3.51 percent vs 5.70 percent; p<0.001).

These were confirmed in fully adjusted Cox regression analyses, which showed that the risk of composite hepatic events were significantly lower in those with normal vs elevated ALT at 3 months (adjusted hazard ratio [HR], 0.61; 95 percent CI, 0.49–0.77; p<0.001), 6 months (adjusted HR, 0.55; 0.45–0.67; p<0.001), 9 months (adjusted HR, 0.54; 0.44–0.65; p<0.001) and 12 months (adjusted HR, 0.51; 0.42–0.61; p<0.001).
