[Extracorporeal detoxification of the body and the B system of immunity in acute peritonitis].

65 patients with acute peritonitis of various etiology have been examined. It has been established that marked toxemia in the early postoperative period, normal relative B-lymphocyte content, low level of EAC-RFC with moderate to high content of receptors to sheep red blood cells are prognostically unfavourable. The level of intermediate molecular mass polypeptides (IMMP) above 0.4 units and absolute absence of B lymphocytes with high receptor density during one postoperative week seem threatening and are an indication for hemosorption (HS). HS in patients with high toxin content was accompanied by a positive clinical effect related to its non-specific stimulation of qualitative and functional B-lymphocyte properties including their receptor apparatus due to IMMP removal from blood.
