Popis: | Introduction: Sarcoidosis is a multisystem granulomatous disease of unknown origin. Pathogenetic involvement of Mycobacterium tuberculosis has frequently been discussed in the aetiology of sarcoidosis; however, studies still remain contradictory. Objective: We addressed the question of mycobacterial involvement in the pathogenesis of sarcoidosis by analysing cellular immune responses to mycobacterial antigens. Methods: We examined the interferon (IFN)-γ production by enzyme-linked immunospot in response to purified protein derivate (PPD) mycobacterial-specific antigen early secretory antigenic target (ESAT)-6 and culture filtrate protein (CFP)-10 by peripheral blood mononuclear cells (PBMCs) and bronchoalveolar-lavage mononuclear cells (BALMCs) of patients with pulmonary sarcoidosis, smear-negative tuberculosis and controls. Results: Release of IFN-γ in response to ex vivo contact with PPD, ESAT-6 or CFP-10 by BALMC and PBMC were comparable among patients with sarcoidosis and controls (PBMC P = 0.2326; BALMC P = 0.1767) and were less frequently observed in both groups compared to patients with tuberculosis (BALMC P |
