[Affinity sorbents having magnetic properties in the clinical picture and diagnosis of communicable and non-communicable diseases]. / Affinnye sorbenty s magnitnymi svoistvami v klinike i diagnostike infektsionnykh i neinfektsionnykh zabolevanii.

ABSTRACT

Affine magnetic sorbents which have no analogs in the practice of our country have been for the first time developed for the rapid diagnosis of various life-threatening diseases (plague, cholera, anthrax, glanders, meliodosis, tularemia, leptospirosis, dysentery, viral hepatitis A) and for the identification of their causative agents. The efficacy of new magnet-controlling test systems has been repeatedly confirmed by their applications in epidemiological events and emergencies in the epidemiological surveillance of viral hepatitis A in Stavropol and in the Caucasian Mineralnye Vody towns, Stavropol Territory (1994), in the identification of cholera patients, in the detection of transmission factors, when monitoring during large epidemic out-bursts of cholera in Stavropol (1990), Daghestan (1994), as well as in the microbiological monitoring during military conflicts in the Chechen Republic (1995). The application of the sorbents has shown that their sensitivity is 4-5 times as much as that of conventional serological assays. In addition, biotechnologies for the production of polyacrylamide and composite aluminosilicate affine immunosorbents with magnetic properties have been developed. They have been used as the basis for designing immobilized granulated antigen reagents for the immunodiagnosis, differential diagnosis, evaluation of the time course and severity of a disease, the efficiency of therapy in patients with systemic scleroderma, proliferative arthritis, systemic lupus erythematosus, juvenile rheumatoid arthritis, osteochondrosis.
