[Serological assessment of destructive processes in the pharynx in conservative and cryosurgical treatment of patients with chronic hypertrophic laryngitis].

The examination of 29 patients with chronic pharyngitis before the treatment, 10 and 30 days after treatment and 18 controls without ENT pathology revealed that the patients' blood and oral fluid contained the antigen inherent for pharyngeal tissue in 24.1 and 89.6% cases, respectively. This antigen was not found in the controls. The appearance of the tissue antigen in the blood and oral fluid may result from destruction of the inflammed tissue and may entail autoimmune reaction. 10 days after conservative anti-inflammatory treatment 12 patients exhibited a temporary clinical and serological effect--improvement of general condition, attenuation of destructive processes, blood and oral levels of the autoantigen and humoral autoimmune reaction to the tissue antigen. 20 days after the treatment clinical and laboratory manifestations renewed. 10 days after cryosurgery antigenemia and autoimmune reaction persisted but 30 days after the treatment the antigen was found neither in the blood nor in the oral fluid, autoimmune reaction declined. This indicates termination of the inflammation and correlates with clinical results.
