[The use of plasmapheresis in the combined treatment of pregnant patients with pyelonephritis].

The results of pyelonephritis treatment in 48 pregnant patients are analyzed. Twenty-three patients were administered routine antibacterial therapy, in 25 ones plasmapheresis was added to it. Immunity status of all the patients was examined. Antibiotic therapy was conducive to improvement of the patients' status, to a reduction of the renal inflammation severity, though it did not completely eliminate immunodeficiency signs. B lymphocyte and immunoglobulin levels persisted reduced. Plasmapheresis promoted a more swift elimination of clinical and laboratory signs of pyelonephritis and virtually completely liquidated immunodeficiency.
