Background:
The key endpoint for treatment efficacy in chronic hepatitis C (CHC) is the absence of a detectable virus at 24 weeks after treatment. This study aims to determine the long-term clinical outcomes in patients with CHC after interferon and ribavirin treatment and the factors that influence them.
Methods:
A retrospective study was conducted on 259 patients with CHC between 2003 and 2021, and the patients were divided into treated (n = 159) and untreated (n = 100) groups. The median observation duration was four years for the treated group (range: 1-15 years) and four years for untreated groups (range: 1-14 years).
Results:
The mean ages of the treated and untreated groups were 47.38 ± 9.07 and 51.17 ± 8.38 years, respectively. Regardless of whether antiviral therapy had been administered, patients with undetectable hepatitis C virus (HCV) load had a lower risk of developing liver cirrhosis and hepatocellular carcinoma (HCC) than patients with detectable HCV load (p < 0.05). Furthermore, patients with HCV genotype 1b were more likely to develop cirrhosis and HCC than patients with HCV non-genotype 1b (p < 0.05). Based on the results of multivariate analysis, age of 50 years and above (hazard ratio [HR] = 6.74, 95% confidence interval [CI] = 2.79-16.28) and infection with HCV genotype 1b (HR = 2.43, 95% CI = 1.06-5.56) were significant predictors of liver cirrhosis and HCC development, whereas undetectable HCV RNA load (HR = 0.14, 95% CI = 0.43-0.46) was a protective factor.
Conclusions:
During the long-term follow-up, no cases of HCC were discovered in patients with undetectable HCV RNA load. Nevertheless, long-term monitoring is still required in patients with liver cirrhosis, since it increases the risk for developing liver cancer.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
