[The pathological anatomy of secondary immunodeficiency].

Secondary immunodeficiency is a polyetiological syndrome resulting mainly from the influence of exogenic factors and manifesting in the lack of immune response and nonspecific defence. Adequate documentation of secondary immunodeficiency revealing its role in the cause-result relationship when analysing the course of disease will improve not only evaluation of events but will create the conditions for the correction of secondary immunodeficiency the feasibility of which is proven experimentally.
