Common variable hypogammaglobulinemia associated with intestinal lymphoid hyperplasia

A case of adult common variable hypogammaglobulinemia with nodular lymphoid hyperplasia characterized by malabsorption and enteric protein loss, probably due to bacterial overgrowth, is reported. This clinical condition is of particular interest because of the unusual pathology and the lack of an efficient treatment. The association between common variable hypogammaglobulinaemia and nodular lymphoid hyperplasia must be considered in young adults with recurrent respiratory tract infection, gastrointestinal symptoms, diarrhoea, hypogammaglobulinemia and low serum albumin.
