Hepatitis C--a risk factor for gallstone disease

Area of Science:

• Hepatology
• Gastroenterology
• Epidemiology

Background:

• Chronic liver disease is a known risk factor for gallstone formation.
• Previous studies suggest a link between Hepatitis C Virus (HCV) infection and gallstones, but often failed to control for confounding factors like cirrhosis.
• This research specifically investigates the HCV-gallstone association while excluding other gallstone risk factors.

Purpose of the Study:

• To determine if Hepatitis C Virus (HCV) infection is an independent risk factor for gallstone disease.
• To quantify the association between HCV and gallstones in a controlled cohort.

Main Methods:

• A cross-sectional study involving 2000 patients undergoing abdominal ultrasound across four hospitals in Rawalpindi, Pakistan, over 18 months.
• Hepatitis C Virus (HCV) antibody testing using ELISA was performed on all participants.
• Abdominal ultrasonography was utilized to diagnose the presence or absence of gallstones.

Main Results:

• Patients with Hepatitis C Virus (HCV) exhibited a significantly higher prevalence of gallstones compared to seronegative individuals (p = 0.001).
• Gallstone incidence was notably higher in males within the HCV-positive group (p < 0.001).
• A significant association was observed between HCV infection and gallstones in younger patients, specifically those aged 40 years or younger (p < 0.001).

Conclusions:

• Hepatitis C Virus (HCV) infection is associated with an increased risk of developing gallstone disease.
• The link between HCV infection and gallstones is more pronounced in male patients.
