Anti-PF4/heparin antibodies are associated with arteriovenous fistula thrombosis in non-diabetic hemodialysis patients

Aim Anti-platelet factor 4/heparin complex antibodies (anti-PF4/heparin Ab) have been found to cause heparin-induced thrombocytopenia (HIT), a clinical syndrome thrombocytopenia and thrombosis. There is still controversy as to whether the presence of anti-PF4/heparin antibodies in hemodialysis patients augments clot formation in access fistula thrombosis, peripheral artery disease (PAD), and coronary heart disease (CHD).
