摘要: Renal symptoms can accompany infectious diseases in two periods: (i) at the time of onset infection, or (ii) after a latent period corresponding to needed for production human antibodies. In first case we talk about early, intrainfectious para-infectious nephritis, and latter, postinfectious glomerulonephritis. Early nephritis is caused with all certainty by primary toxic effects, while development glomerulonephritis antigen-antibody reaction plays decisive role. It was realized as early beginning this century that scarlatinal an allergic disease [265]. Since then number explanations have been put forward aetiology pathomechanism post-streptococcal including theory autoimmunization. Nevertheless, no final solution problem has reached. Some authors are opinion autoimmunization not cause but consequence renal disease.
