ABSTRACT
The IgG subclass deficiency is defined as a significant decrease in the serum concentrations of one or more subclasses of IgG in a patient whose total IgG concentration is normal. IgG subclass deficiency can predispose to recurrent sinopulmonary infections. A 29-year-old female patient with a 4-year history of bronchial asthma presented with cough, sputum, dyspnea, and recurrent respiratory infections. She had frequently been treated with antibiotics and systemic steroids for recurrent respiratory infections and acute asthma exacerbations. Chest X-ray and computed tomography showed pectus excavatum and bronchial wall thickening without lung parenchymal abnormalities. On immunological evaluation, she was found to have a low serum IgG3, with normal total IgG concentration. Under diagnosis of selective IgG3 deficiency, she was started on monthly infusions of intravenous immunoglobulin (IVIG) therapy. The frequency and severity of respiratory infections and acute asthma exacerbations were markedly decreased during 3 years of IVIG therapy. Our case report suggests that a patient who has underlying selective IgG3 deficiency and asthma may benefit from IVIG therapy as this can significantly reduce the incidence and severity of recurrent respiratory infections and acute asthma exacerbations.
