Quantitative levels of immunoglobulin E (IgE) were determined in samples of sera obtained from 29 patients with proven moderate to far- advanced tuberculosis. The sensitive radioimmunoassay test for IgE was used. Statistical analysis of the results revealed no difference in IgE values as compared to a control group of normal sera. In contrast to other chronic pulmonary infections, such as bronchopulmonary aspergillosis, the IgE level in pulmonary tuberculous infection is of no diagnostic significance. Simultaneous determination of levels of immunoglobulins G, A, M, and D (IgG, IgA, IgM, IgD) in these same sera by radial immunodiffusion showed elevated IgG and lowered IgM levels in the tuberculous patients, confirming previous studies. The significance of these alterations in immunoglobulin levels is unclear and may represent a secondary phenomenon rather than a primary host response.
