[Common variable immunodeficiency. Report of a case and review of the literature].

A ten year old boy was referred to the allergy clinic due to a chronic history of upper respiratory infections, otitis media, recurrent sinusitis, wheezing and chronic cough that initiated at six years of age. He did have some very small lymph nodes in the cervical area. Serum immunoglobulins were very low which suggested the diagnosis of a common variable immuno-deficiency, a disease with features of increased susceptibility to infection, diarrhea, malabsorption and major complications that include bronchiectasis, autoantibody formation, and autoimmune disease. The patient received IVIG and has doing well.
