B2 microglobulin in the diagnosis and prognosis of postoperative infectious complications in the pulmonary surgery

: The radioimmunoassay was used to study blood serum B2-M levels in 56 patients with pulmonary diseases (lung carcinoma in 20, chronic suppurative lung disease in 20, and benign lung disease in 16 patients) before the operation and in the early postoperative period. The control group was formed of 21 practically healthy individuals. A direct correlation between the character of the course of the postoperative period in patients with benign and chronic pulmonary diseases and the dynamics of changes of immunoreactivity (IR) was found. A favorable course of the postoperative period was marked by an increase of IR, in postoperative infectious complications IR did not change. Dynamics of IR was not revealed in patients with lung carcinoma, irrespective of the course of the postoperative period.
