Background:
A prevalence of 1.2% of coeliac disease (CD) in patients with chronic hepatitis C was recently reported, suggesting a possible epidemiological link between these two diseases. However, other studies have not found this relationship.
Aim:
To conduct a French multicentre prospective study to assess the prevalence of CD in hepatitis C virus (HCV)-infected patients.
Methods:
Between June 2003 and November 2005, 624 consecutive HCV-positive out-patients were tested for antiendomysial IgA antibodies (AEA), antigliadin IgA and IgG antibodies (AGA). Patients with positive AEA or IgA AGA and positive IgG AGA in a context of a high suspicion of CD were asked to undergo gastroscopy with duodenal biopsies.
Results:
Isolated IgA AEA, IgA AGA and IgG AGA were 0.16%, 5.7% and 4.4%, respectively. Gastroscopy was required for 39 patients, 31 were performed (eight refusals), but only 25 duodenal biopsies were performed as six patients had cirrhosis. CD was never detected.
Conclusions:
The prevalence of CD in HCV-positive patients was 0% (95% confidence interval: 0-0.59%), but there is a low prevalence of CD in the whole French population.

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...
