Common variable immunodeficiency, insulin-dependent diabetes mellitus and celiac disease

Common variable immunodeficiency is a disorder characterised by hypogammaglobulinemia with B-lymphocytes in peripheral blood and repeated infections. We report a child with a diagnosis of diabetes mellitus and celiac disease during lactation, and in whom common variable immunodeficiency was diagnosed at the age of 5. During evolution of the disease he presented multiple respiratory infections in spite of substitution therapy with gamma globulins. He presented pulmonary fibrosis with a pulmonary volume reduced, and a spirometric restrictive patron. Immunologically, he presents reduction in CD4 lymphoid population. He expresses the alleles DQ2 A1 0501 and B1 which are strongly associated with susceptibility to insulin-dependent diabetes mellitus and celiac disease, but don't express antigens HLA class II DR3 and DR4 that are more frequent in these entities. The main disease and all the complications had affected his curve pondostatural.
