Possibility to Stop Perdialytic Heparin Therapy in Hemodialysed Patients With HeprAN ™ Membrane and Treated by Long-term Anticoagulation With VKA (REMARK)

July 3, 2020 updated by: CHU de Reims

Feasibility to Stop Perdialytic Heparin Therapy in Hemodialysed Patients With HeprAN ™ Membrane and Treated by Long-term Anticoagulation With VKA

Use HeprAN ™ membrane (coated with heparin) should be allow the success of dialysis sessions, with adequate dialysis parameters, in patients treated by long-term anticoagulation with VKA, without addition of heparin perdialytic.

Less use of heparin (UFH or LMWH) during hemodialysis session should be allow a decrease of bleedings (moderate or major) and blood transfusions for hemodialysed patients with HeprAN ™ membrane and treated by long-term anticoagulation with VKA

Detailed Description

The aim will be to study possibility of hemodialysis sessions success, without perdialytic anticoagulation but with adequate dialysis parameters (defined by the patient's Kt / V machine), in patients treated by long-term anticoagulation with VKA and dialysed with the HeprAN ™ membrane.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: single-arm study
Chronic hemodialysis patients for at least 3 months at Reims University Hospital, treated by long-term anticoagulation with VKA and dialysed with the HeprAN ™ membrane
Drug: Decrease per-dialytic heparin therapy
Week 1: maintenance's dose stop Week 2: 50% drop in the loading dose Week 3: complete cessation of heparin therapy during the session.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Failure of heparin withdrawal in patients treated by long-term anticoagulation with VKA and dialysed with the HeprAN ™ membrane, verify adequate dialysis parameters
Time Frame: 3 weeks

Failure is defined by

  • early interruption of the dialysis session (<95% of the prescribed time) for :
  • extracorporeal circuit coagulation
  • recurrent venous pressure alarm causing blood pump shutdown or
  • Lower quality of dialysis compared to the quality before stopping perdialytic anticoagulation (defined as Kt/V less than - 2SD for 3 consecutive sessions)
3 weeks
