[Dynamics of humoral immune response to Treponema pallidum proteins p17 and p41 at early stages of syphilis].

| Abstract |
In 60 blood sera from syphilis patients the titers of IgG to T. pallidum antigens p17 and p41 were detected with the use of the test system based on the recombinant analogues of T. pallidum proteins. The study revealed that primary syphilis was characterized by considerable prevalence of IgG to protein p41 with the total antibody level being low, while early latent syphilis was characterized mainly by considerable prevalence of IgG to protein p17 in the presence of high titers of antibodies. In secondary syphilis the sera contained a high total antibody level and a wide range of IgG ratios to individual antigens. On the basis of the data obtained the dynamics of immune response to antigens p17 and p41 at the early stages of the disease was hypothetically plotted. The curves of antibody levels had a wave-like character with the phase shifts of peaks for individual proteins and very low antibody titers (less than 1:100) in the negative peak areas. Conclusions were made that it was necessary to use the mixture of antigens in the production of the test systems and, when designing reference panels of sera, to include sera with extremely low titers of antibodies to individual proteins.
