title: Celiac disease onset after pegylated interferon and ribavirin treatment of chronic hepatitis C.
abstract: OBJECTIVE
  Report of a case of a woman patient who developed celiac disease after pegylated interferon alpha-2a and ribavirin use for chronic hepatitis C.
  
  
  METHODS
  A 34-year-old woman with chronic hepatitis C, genotype 3, receiving pegylated interferon alpha-2a and ribavirin for 6 months, developed progressive malaise and anemia 6 months after the end of treatment.
  
  
  RESULTS
  Additional investigation revealed duodenal villous atrophy and positivity for anti-endomysium and anti-gliadin antibodies. Celiac disease diagnosis was performed and symptoms and laboratory abnormalities improved after gluten-free diet.
  
  
  CONCLUSIONS
  Celiac disease must be ruled out in patients with malabsorption complaints in or after interferon (or pegylated interferon) therapy. Screening for celiac disease with detection of anti-endomysium antibodies would be done in susceptible patients.
