Increased Levels of IgG4 Subclass in 5 Patients with Acquired Respiratory Disease

Abstract
5 sera from a series of more than 1,000 serum samples from hospitalized patients tested by immunoelectrophoresis were selected for further examination because of a disproportional increase in the anodic part of IgG. A marked polyclonal increase in IgG4 subclass level was detected in each of these sera. While the patients suffered from a variety of diseases (e.g. Loeffler’s syndrome, leiomyosarcoma, periarteritis nodosa, chronic bronchitis, and mycosis fungoides, respectively), they all had an acquired respiratory disease as the only common clinical denominator.
