[Common variable immunodeficiency and total villous atrophy regressive after gluten-free diet].

A patient with a commun variable immunodeficiency (CVID) is hospitalized for chronic symptoms of malabsorption (weigh loss and diarrhea). The duodenal histology show a total villous atrophy. Investigations are negative and a gluten free diet is given. Symptoms of malabsorption disappear and improvement is histologically confirmed. Our observation suggest that the coincidence of gluten sensitive enteropathy and CVID is possible and clinicians should be aware of this association and should consider giving a gluten free diet. The sensitivity of serologic testing in this conditions is unknown.
