ABSTRACT
Introduction: Common variable immunodeficiency (IDVC) is a relatively frequent primary immunodeficiency due to antibody deficiency. It is considered a genetic disorder due to the presence of mutations in genes that code for a particular component of the adaptive immune system. It is characterized by a decrease in serum levels of IgG, IgA and sometimes IgM. The clinical picture is highly variable and four clinical phenotypes are described.Case presentation: A 16-year-old patient, who presented from the first year of life had high and low respiratory infections, complicated and uncomplicated. There were more than 10 episodes in a year, mainly of bacterial etiology, with multiple admissions and broad-spectrum antimicrobial treatments. Personal and family history of asthma, atopic dermatitis and recurrent eczemas were reported. He also presented gastrointestinal disorders of different causes and milk intolerance. On one occasion, he was admitted for an adenian syndrome, which was interpreted as an infectious mononucleosis. Immunological studies were performed due to a complicated pneumonia finding a decrease in serum IgG levels and a decrease in the CD19 positive lymphocyte population was confirmed by flow cytometry. He was treated with intravenous gammaglobulins with good response.
Conclusions: In the presence of bacterial infections, mainly of bacterial origin, it is important to think about this disease, since diagnosis and timely treatment improve the patient’s quality of life.
