An unusual case of sinusitis

Common Variable Immunodeficiency (CVID) is the commonest form of severe antibody deficiency. It is characterized by reduced levels of IgG (<400 mg/dL) and low IgA and/or IgM levels, recurrent bacterial infections, impaired antibody responses despite the presence of B Cells and normal or near normal T immunity in 60% of patients. There is a high mortality from infections without treatment. The main stay treatment is to replace the immunoglobulins.

We describe a British soldier with a 10 year history of recurrent chest infections, sinusitis and otitis media. He repeatedly presented 2 to 3 times a year complaining of either a green nasal discharge or a cough productive of yellow/green sputum. He presented three years ago with severe sinusitis which resulted in investigations highlighting hypogammaglobulinaemia. Subsequently he was started on immunoglobulin therapy with Flebogamma 40 g three weekly.

Despite being a relatively rare condition, CVID when diagnosed, can be easily treated and improve patients' prognosis. Medical Officers should be aware of the condition as a differential diagnosis for individuals presenting with recurrent infections.
