Thrombocytopenic purpura and coeliac disease.

In a child with immune thrombocytopenic purpura (ITP) the findings of circulating reticulin antibodies and IgA and IgG gliadin antibodies suggested the diagnosis of coeliac disease. This was verified by small intestinal biopsy. In spite of a gluten-free diet the thrombocytopenia persisted. The association of ITP and coeliac disease was previously described in adults but to our knowledge this is the first report of the coexistence of ITP and coeliac disease in a child.
