LMWH Infusion as Anticoagulation for Home HD

Phase 4
Conditions
Endstage Renal Disease
Interventions
Registration Number
NCT02957877
Lead Sponsor
Alice Ho Miu Ling Nethersole Hospital
Brief Summary

There is a lack of data in the literature about the use of low-molecular weight heparin (LMWH) as anticoagulation for nocturnal home hemodialysis (NHHD). This study aims to evaluate the efficacy and safety of LMWH, administered by infusion method, as compared to unfractionated heparin as anticoagulation for NHHD treatment.

Detailed Description

Low-molecular weight heparin (LMWH) and unfractionated heparin (UFH) are established systemic anticoagulants for the patients who receive conventional thrice-weekly hemodialysis in absence of significant bleeding risk. For the patients who undergo nocturnal home hemodialysis (NHHD), LMWH is seldom utilized because of the need of an additional bolus injection during a long dialysis treatment, which is impractical as the patients are sleeping during hemodialysis. Moreover, there is a potential risk of LMWH accumulation due to its longer half-life. As there is a paucity of data in the literature on the use of LMWH for NHHD treatment, this trial is conducted to assess the safety and efficacy of LMWH, administered by infusion method, in this particular group of dialysis patients.

UFH armUnfractionated heparin8-hour hemodialysis is performed on alternate day for a week at the dialysis unit (i.e. 3 sessions) by using unfractionated heparin as anticoagulation
LMWH armNadroparin8-hour hemodialysis is performed on alternate day for a week at the dialysis unit (i.e. 3 sessions) by using low-molecular weight heparin (nadroparin) as anticoagulation
Primary Outcome Measures
NameTimeMethod
Prothrombin timePre-dialysis; the 2nd, 4th, 6th and 8th hours of dialysis

Prothrombin time is monitored in both of the LMWH and UFH arms

Anti-Xa levelPre-dialysis; the 2nd, 4th, 6th and 8th hours of dialysis; 24 hours after administration of LMWH

Anti-Xa level is only monitored in the LMWH arm

Activated partial thromboplastin timePre-dialysis; the 2nd, 4th, 6th and 8th hours of dialysis

Activated partial thromboplastin time is monitored in both of the LMWH and UFH arms

Dialyser urea and creatinine clearancesAt 15 mins after starting hemodialysis and 15 mins before the end of hemodialysis

Dialyser urea and creatinine clearances are evaluated in both of the LMWH and UFH arms

Dialyser thrombus scoreAt the end of hemodialysis (8th hour)

Dialyser thrombus score is evaluated in both of the LMWH and UFH arms
