On the dynamics of antistreptolysin-o and c-reactive protein titers in various forms of rheumatism

To assess the reactivity of the body in rheumatism, depending on the phase of the process in modern rheumatology, immuno-biological tests are widely used - such as skin tests according to V.I. Ioffe, the detection of anti-streptococcal antibodies, as well as indicators of the severity of the process - the determination of C-reactive protein and microbial antigen (V. Tsonchev, St. Kolarov, N. Popov, At. Karakashov). According to most authors (A.N. Nesterov, J.-J. Rappoport, etc.), antistreptolysin-O titers increase in the acute period of rheumatism, as well as in relapses. At the same time, there is a well-known correspondence between the dynamics of antibody titers and the activity of the rheumatic process.
