12 patients suffering from sarcoidosis have been studied in addition to clinical and bioptic investigations, they were submitted to intradermal reaction with PPD, Candida Albicans and Kveim's antigen. Lymphocytes from the 12 patients were placed in culture and stimulated with phytohaemagglutinin (PHA), pokeweed mitogen (PWM), concanavalin A (CON-A), PPD, Candidin and Kveim's antigen. Six patients proved positive to Kveim's antigen in vivo, and four of them (66%) in vitro also. No patient was immunodepressed. Of the 6 patients negative to Kveim's antigen both in vivo and in vitro, 4 were clearly immunodepressed, as shown by the reduced mitogen response, the negative response to antigen stimulation, and to the intradermal reaction. The results are discussed in the light of recent findings regarding the role of the immunocompetent system in sarcoidosis.

Abstract

12 patients suffering from sarcoidosis have been studied in addition to clinical and bioptic investigations, they were submitted to intradermal reaction with PPD, Candida Albicans and Kveim's antigen. Lymphocytes from the 12 patients were placed in culture and stimulated with phytohaemagglutinin (PHA), pokeweed mitogen (PWM), concanavalin A (CON-A), PPD, Candidin and Kveim's antigen. Six patients proved positive to Kveim's antigen in vivo, and four of them (66%) in vitro also. No patient was immunodepressed. Of the 6 patients negative to Kveim's antigen both in vivo and in vitro, 4 were clearly immunodepressed, as shown by the reduced mitogen response, the negative response to antigen stimulation, and to the intradermal reaction. The results are discussed in the light of recent findings regarding the role of the immunocompetent system in sarcoidosis.
