Inclusion Criteria:

  • Cirrhosis with ascites.

Exclusion Criteria:

  • Evidence of chronic kidney disease Stage 4.
  • Patients with Model for End-Stage Liver Disease (MELD) score > 40 (since these patients are unlikely to survive a 90-day follow-up period).
  • Acute or chronic use of circulatory support device.
  • Mechanical ventilation for greater than 7 consecutive days.
  • AKI occurring in the setting of burns, obstructive uropathy, allergic interstitial nephritis, acute or rapidly progressive glomerulonephritis, vasculitis, hemolytic uremic syndrome, thrombotic thrombocytopenic purpura (TTP), malignant hypertension, scleroderma renal crisis, atheroembolism, functional or surgical nephrectomy, cyclosporine or tacrolimus nephrotoxicity. No evidence of intrinsic parenchymal renal disorder, ultrasonic evidence of obstructive uropathy or proteinuria greater than 500 mg/day.
  • Presence of any organ transplant at any time.
  • Metastatic malignancy which is actively being treated or may be treated by chemotherapy or radiation during the subsequent three-month period after study protocol therapy.
  • Severe, uncontrolled cardiac disease.
  • Chronic immunosuppression.
  • Medical history of HIV or AIDS.
  • Current Do Not Attempt Resuscitation (DNAR), Allow Natural Death (AND), or withdrawal of care status, or anticipated change in status within the next 7 days.
  • Patient is moribund or chronically debilitated for whom full supportive care is not indicated.
  • Dry weight >150 kg.
  • Platelet count <30,000/mm3.
  • Concurrent enrollment in another interventional clinical trial. Patients enrolled in clinical studies where only measurements and/or samples are taken (i.e., no test device or test drug used) are allowed to participate
  • Use of any other investigational drug or device within the previous 30 days
  • Patient is a prisoner.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Selective Cytopheretic Device

Arm Description

Subjects will be placed on Selective Cytopheretic Device (SCD) for planned daily 24 hour therapy for up to 7 consecutive days.

Outcomes

Primary Outcome Measures

Number of serious adverse events related to selective cytopheretic device (SCD)
Number of deaths related to selective cytopheretic device
Number of events of significant clotting within the device as assessed by visual inspection
Source documentation will record either present, absent, or not-assessed
Number of unforeseen malfunction(s) that results in the need for discontinuation
Number if events with evidence of leakage (i.e., cracking/breakage of a port, connector, SCD casing cartridge or tubing).

Secondary Outcome Measures

Dialysis independence
Dialysis independence at days 1-5 post SCD, and at days 30 and 90 (+/- 7 days). Dialysis independence will be assessed using the medical record.
Change in renal function
As measured by serum creatinine from baseline (prior to dialysis initiation) at days 1-5 post SCD and at days 30 and 90 (among survivors and those free from dialysis).
Change in liver function
Measured by blood tests of liver function parameters such as AST, ALT, alkaline phosphatase
Change in liver function
Measured by blood test of bilirubin
Change in coagulation parameters
Coagulation parameters include Prothrombin Time (PT), Activated Partial Thromboplastin Time (PTT), and International Normalized Ratio (INR) all reported in seconds
Change in model for end-stage liver disease (MELD) score
MELD score is a number that ranges from 6 (least sick) to 40 (most sick) based on blood tests which ranks the degree of sickness from liver disease.

Intervention Name(s)
Selective Cytopheretic Device
Intervention Description
The Selective Cytopheretic Device (SCD) treatment will be delivered using a two-cartridge system using a type of dialysis equipment commonly used for conventional hemodialysis therapy. The SCD cartridge will be added immediately post-hemofilter to the circuit of a standard hemodialysis system, and treatment will be delivered for 24 hours. Blood exchange will occur using a dialysis catheter.
