Inherited antithrombin deficiency and end stage renal disease.
Antithrombin is a potent inhibitor of the coagulant effect of thrombin. In the latter half of 20th century, many families have been described in which an autosomaly dominant inherited antithrombin deficiency has caused severe venous thromboembolic disease in successive generations. The important complication is severe venoocclusive disease by deep venous thrombus. Some inherited antithrombin deficient patients developed renal failure because of fibrin deposition in the kidney glomeruli or renal vein thrombus, and therefore the need for replacement therapy for end stage renal disease (ESRD). Although an inherited antithrombin deficiency with renal failure is rare, prevention against renal failure in such patients, and their renal replacement therapy for ESRD are important. Proteinuria decreases plasma antithrombin level leading to more severe hyper-coagulation state. Therefore early in renal disease, it may be prudent for adaptation of anti-coagulation therapy even if recurrent thrombosis has not occurred. All replacement therapy (hemodialysis, transplantation or peritoneal dialysis) for ESRD are available for such thrombophilic disorders. Anticoagulation agents working without aggravation of antithrombin effects (Argatroban, Nafamostat mesilate etc.) are useful for hemodialysis. The renal allograft recipients with thrombophilia seem to be at risk of developing an acute rejection or other vascular event. Peritoneal dialysis is potentially a good adaptation for such thrombophilic disorders. However which therapy has the best mortality and morbidity outcomes is not clear. Physicians and Surgeons must pay attention to the coagulation state and thrombophilia in ESRD patients, give strong consideration for adequate anti-coagulation therapy and review the best renal replacement modality for each patient.
