The primary objective of this study is to determine whether a dose-adjusted prophylaxis fondaparinux regimen of 2.5 mg subcutaneously administered q 48 hr in patients with renal failure achieves peak and trough levels similar to patients with normal renal function, and protects patients from developing VTE. Our hypothesis is that a dose-adjusted fondaparinux regimen, which extends the dosing interval from q24 to q48 in patients with estimated creatinine clearance of < 30 ml/min will be safe and effective.

Primary Outcome Measures:
  • Efficacy of the adjusted dose in achieving peak and trough levels similar to patients without renal failure [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Levels will be assessed throughout the study

Secondary Outcome Measures:
  • Safety [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]
    Safety will be assessed through monitoring for bleeding as well as doppler monitoring at the beginning and end of the study.

Arms Assigned Interventions
Experimental: Renal failure, on IHD
These are patients with renal failure, on intermittent dialysis
Drug: Fondaparinux
2.5 mg every 48 hours
Other Name: Arixtra
Experimental: Renal failure, on CRRT Drug: Fondaparinux
2.5 mg every 48 hours
Other Name: Arixtra
Experimental: Renal failure, not on dialysis
These are patients with acute kidney injury not yet on dialysis
Drug: Fondaparinux
2.5 mg every 48 hours
Other Name: Arixtra

Detailed Description:

We will be studying fondaparinux 2.5 mg subcutaneously every 48 hr in three distinct patient groups: 1) Acute kidney failure without hemodialysis, 2) Acute kidney failure with intermittent hemodialysis and 3) Acute renal failure with continuous renal replacement therapy. All patients will be assessed for efficacy of the dose. Efficacy will be assessed by following clinically for any evidence of VTE, either deep venous thrombosis or pulmonary embolism. In addition, lower extremity duplex studies will be performed at baseline and at the end of the study period to assess for DVT.

Secondary objectives will be safety and accumulation. Safety will be determined by assessment of clinically significant bleeding, defined as a drop in Hgb of > 2gm in 24 hr, or the need for red blood cell transfusion related to bleeding. Accumulation may occur in renal failure and will be studied throughout the ICU stay through reevaluation of levels over time.
