[Examining of humoral immunity on mycobacteria antigens in sarcoidosis].
Antibodies to Mycobacterium tuberculosis antigens H37Rv and reverse strains previously isolated from patients with sarcoidosis with granular isolates were determined in 50 patients with sarcoidosis (including 16 patients isolating granular types) and 56 patients with tuberculosis, by using ELISA and immunoblotting. Serum antibodies from patients with sarcoidosis were ascertained to more commonly react in ELISA with the antigen (ultrasound disintegrant (USDs) obtained from reverse mycobacteria isolated (initially) from patients with sarcoidosis (AGS) than with the USD of the M. tuberculosis H37Rv (AGT) and, on the contrary, serum antibodies from patients with tuberculosis more frequently reacted with the M. tuberculosis H37Rv. The spectrum of serum antibodies from patients with sarcoidosis greatly differed at immunoblotting with AGS and AGT. There was most commonly a reaction with the antigenic determinants 79, 27, 30, and 50 kDa to AGS and that of the determinants 17, 35, 32 kDa to AGT.
