Seronegative autoimmune hepatitis presenting after diagnosis of coeliac disease: a case report.

The relationship between liver dysfunction and coeliac disease is well established, ranging from transaminitis to chronic liver disease. In this report, we describe for the first time the development of a 'seronegative' autoimmune hepatitis in a teenager previously diagnosed with coeliac disease. He had normal liver function tests (LFTs) at diagnosis and was strictly compliant with a gluten-free diet. On screening blood tests at 1 year post diagnosis, he presented with raised LFTs leading to a diagnosis of autoimmune hepatitis on liver biopsy, successfully treated with mycophenolate mofetil. By using screening LFTs, we may well have prevented this patient from developing disease complications.
