Effect of hemodialysis on contact group of coagulation factors, platelets, and leukocytes

Earlier reports have suggested possible activation and consumption of factor XII during hemodialysis. To investigate this possibility, a series of in vivo and in vitro experiments were conducted using different dialysis membranes and two different dialysates (acetate and bicarbonate). Factors XII and XI activities, factor XII concentration, and high-molecular-weight kininogen were measured. In addition, platelet count, white blood cell count, and hematocrit were monitored. Contrary to the previous reports, no discernible consumption of factor XII, factor XI, or high-molecular-weight kininogen was found irrespective of the type of membrane or the composition of the dialysate used. Transient leukopenia was noted with cellulosic membranes, whereas none occurred with polyacrylonitrile dialyzers. The composition of dialysate did not affect the white blood cell count during dialysis.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
