[Immunodeficiency states in lung diseases and the possible ways for their correction]

The author discusses problems on the mechanisms of formation of immunodeficiency state in pulmonary diseases. It is suggested that T-cell deficit revealed in pulmonary pathology is caused by several factors (intoxication, mediators of allergic-reactions immune complexes, C-reactive protein, hormones, endorphin-like substances etc.), the removal of which furthers normalization of the immune system. Data are reported on the possible variants of secondary immunodeficiency states and the main regularities for immunocorrection are discussed.
