Background:

Common Variable Immunodeficiency (CVID) is the most frequent type of severe primary immunodeficiency (PID). Clinical manifestations of CVID occur at any age; nevertheless, they are more frequent between the age of 6 and 10 years, and between the age of 20 and 40 years. In medical literature, there are hardly any diagnostic reports on CVID after 50 years of age.

Clinical case:

A 58-year-old man with a clinical history of repeated infections since the age of 35. The tests showed a decrease in IgG, IgA, and specific antibodies, without any other causes of hypogammaglobulinemia. The CVID diagnosis was made and the patient received treatment with human immunoglobulin replacement and a reinforcement of personal and environmental hygiene. The patient stopped presenting repeated infections.

Conclusion:

Diagnoses made after the age of 50, although they’re late, they are fundamental to the recovery of the patient. In the referred case, replacement with human immunoglobulin allowed an improvement in the quality of life.
