Three cases of adult coeliac disease with severe vitamin B12 deficiency not accompanied by folate or iron depletion are presented. Two of the patients had the extremely rare combination of coeliac disease and lack of intrinsic factor and autoimmune thrombocytopenic purpura. A close association between coeliac disease and autoimmunity is indicated by the development of autoimmune thyroiditis in the third patient. Vitamin B12 malabsorption caused by coeliac disease is emphasized as a pathogenetic mechanism of megaloblastic anaemia.

A patient had a rare association of celiac disease, keratoconjunctivitis sicca, and autoimmune thrombocytopenia. Both the malabsorption and the thrombocytopenia responded to prednisone therapy. The development of three different autoimmune disorders in this patient may be related to the presence of HLA-B8 and HLA-Dw3, the prevalence of which is known to be increased in celiac disease and keratoconjunctivitis sicca and that of HLA-B8 in autoimmune thrombocytopenic purpura. Despite the fact that thrombocytopenia is rarely encountered in celiac disease, it is suggested that an autoimmune mechanism should be excluded in patients with this combination.
