Coupled Plasma Filtration Adsorption
Coupled Plasma Filtration Adsorption
 Coupled Plasma Filtration Adsorption
An extracorporeal blood purification technic which
includes 2 steps :
1. A plasma adsorption loop
2. A hemofiltration
This allows to remove small and medium molecules
by hemofiltration while specific removal of larger ones
such as inflammatory mediators of bilirubin are
removed by adsorption

Bilirubin Adsorbent Column for Plasma
Perfusion
• 1998年, 日本學者提出
1. Hemodialysis, HD: 只能清除小分子水溶性毒素，無法有效移除
膽紅素以改善肝衰竭病徵
2. Hemofiltration, HF: 無法有效清除與白蛋白結合之膽紅素，因
此也不建議使用
3. Plasma Exchange, PE: 大量輸注血漿，需考量有感染血液傳播
性疾病以及過敏反應等之風險

CPFA in ICU
• For Liver Failure
• The sorbent removes bilirubin, pro
and anti-inflammatory mediators
• Blood flow : 180-200 ml/min
• Hemofiltration flow : 35ml/kg/hr
• Plasma flow : 20% x blood flow
• Duration : 4-8 hours
• Sessions :Based on the clinical
condition, 1-4 per patient
Note : the same circuit with different sorbents can be used for severe
sepsis or septic shock, or renal ABO incompatibility

 CPFA clinical use
Case Report 1
 27-year-old man with Weil’s syndrome who was
admitted to ICU with septic shock and anuria
refractory to fluid therapy, ARDS, and hepatic
involvement (intubation, MV support and
vasopressor infusion)
 Weil’s syndrome: leptospirosis characterized by
jaundice, renal failure and hemorrhagic diathesis.
 Pathogenesis: leptospires and with the subsequent
systemic inflammatory response
Coupled plasma filtration-adsorption in Weil’s syndrome: case report,
R. MORETTI,MINERVA ANESTESIOLOGICA, 2011/08
Case Report 1
 CPFA was started early after the onset of septic shock
 Five courses of CPFA were performed.
 Each course lasted for 10 h with 14 h interval
 Day 2: Weaning from vasopressors
 Day 6: Weaning from ventilation
 Day 8: Creatinine clearance: 63 ml/min
 Day 11: Discharged
Coupled plasma filtration-adsorption in Weil’s syndrome: case report,
R. MORETTI (Italy),MINERVA ANESTESIOLOGICA, 2011/08
Case Report 2
 2 patients:
 After liver transplantation
 1#: Aarly allograft dysfunction (Bil: 25.5)
 2#: Hyperbilirubinemia linked to chronic rejection (Bil:22)
 Accept 3 cycles (6 hours) of CPFA
 Bilirubin promptly decreased in both cases (Bil: 4; 2)
 Each cycle of treatment lowered the bilirubin by ~40%
 CPFA: a potential inexpensive short-lasting device to
treat hyperbilirubinemia after liver surgery or
transplantation.
U. Maggi (Italy),Transplantation Proceedings, 45, 2715e2717 (2013)
A pilot study
 Subjects: Ten patients with hyperdynamic septic
shock
 Interventions: Patients were randomly allocated
to 10 hrs of either
 CPFA (treatment A)
or
 CVVHDF (Continuous venovenous hemodiafiltration
(treatment B)

CPFA: A Single Center Experience
(Universiti Kebangsaan Malaysia Medical Centre)
 Patients and Methods:
 A retrospective review: septic patients who
received CPFA
 All patients were initially treated according to the
‘surviving sepsis care bundle’ with fluid
resuscitation, antibiotics, and inotropes
 CPFA was started after a nephrologists’
assessment (already had AKI and metabolic
acidosis)

CPFA: A Single Center Experience
(Universiti Kebangsaan Malaysia Medical Centre)
 25 patients with sepsis received CPFA
 15 M, 10 F, mean age 49.60 ± 18.97 years
 All patients received one cycle of CPFA with
median duration of 5 (1-10) hours
 Technical problems: filter clotting as CPFA was
performed heparin free (citrate)
 14 (56%) patients died within 28 days of
treatment.
Rizna Abdul Cader ,Nephro-Urology Monthly. 2013 September; 5(4):891-6
CPFA in Patients With Severe Acute Pancreatitis
 Observational cohort study, 25 patients with SAP
 12 received CPFA plus CVVH treatment(group 1)
 13 received CVVH therapy (group 2)
 All the patients underwent 10-day intervention.
 Compared with 2 group
 Better in grope 1 (P<0.01): PaO2/FiO2, mean arterial
pressure, serum amylase, and blood urine nitrogen
 Reduced in group 1 (all P<0.01): Serum TNF-a, IL-1b,
IL-6
 28-day survival rate of group 1 was higher than that in
group 2

CPFA in Patients With Severe Acute Pancreatitis
 CPFA combined with CVVH was an effective
and safe method for treatment of SAP
patients
 Mechanism: effect on regulating the level of
cytokines and serum amylase

able to reduce mortality and prevent organ
failures in septic shock patients in intensive
care unit (ICU)
 Study Type: Interventional
 Study Design:
 Allocation: Randomized
 Endpoint Classification: Efficacy Study
 Intervention Model: Parallel Assignment
 Primary Outcome Measures : Hospital mortality

Take Home Message
 CPFA , as an artificial liver support system, can be
also used for treatment of sepsis, septic shock
and severe acute pancreatitis
 Circuit and seeting:
 Large RCT for the relationship of CPFA used and
mortality was still proceeding
