Migratory pneumonia caused by common variable immunodeficiency disorder

Recurrent respiratory infections are important causes for bronchiectasis which can also be caused by a severe or poorly treated single infective event. With the widespread usage of vaccines for whooping cough and measles and the efficacy of anti-tuberculosis chemotherapy, the latter cause has receded as predisposing factor to developing bronchiectasis especially in the developed world. Primary antibody deficiency syndromes (PADS) are uncommon causes for recurrent respiratory infections and bronchiectasis. The importance of a timely diagnosis of such conditions is that treatments are available and can prevent the development of bronchiectasis. I here report the case of a young gentleman who suffered from recurrent pneumonias for seven years before identifying common variable immunodeficiency disorder as the underlying disease.
