Massachusetts General Hospital Guidelines* for
the use of Recombinant Human Activated Protein C (rhAPC) in Severe Sepsis
Volume XI, Issue 10
Inclusion Criteria
To be considered for rhAPC therapy the patient should have:
- A known or suspected site of infection as indicated by one or more
of the following:
- Purulent sputum or respiratory sample or a CXR with new infiltrates not
explained by a non-infectious process
- Spillage of bowel contents noted during an operation
- Radiographic or physical exam evidence of an infected collection
- White blood cells in a normally sterile body fluid
- Positive Blood culture
- Evidence of infected mechanical hardware by physical or radiological exam
- Evidence of systemic inflammation syndrome as indicated by at least 3
of the following:
- Fever or hypothermia: core temp > 38° C or < 36° C
- Respiratory Dysfunction as defined as
1)Tachypnea: > 20 breaths/minute or
2) Mechanical ventilation for an acute process or
3)PaCO2<32mm Hg
- Heart rate:> to 90 beats/minute.
Patient only needs to meet 2 of the other criteria if:
1) the patient has a pacemaker, or
2) the patient is on pharmacological therapy for a pre-existing tachycardia
- White Blood Cell Count: > 12,000 cells/mm3 or <
4000 cells/mm3 or 10% bands on WBC differential
- Sepsis-Induced Organ Failure Criteria:
Note: Organ failures may not be explained by another non-sepsis illness,
and cannot be greater than 48 hours old in duration
The patient must either have evidence of septic shock defined as:
- The need for vasopressors to maintain adequate blood pressure after an adequate
volume replacement or fluid challenge
OR
In the absence of septic shock, the patient should have 2 or more
of the following organ failures:
- Respiratory: PaO2/FIO2 ratio < 200
- Renal: Urine output < 0.5 ml/kg/hr for 2 hour in the face of adequate
intravascular volume (CVP > 8 or PAWP > 12), or after
an adequate fluid challenge (12 cc/kg) has been given
- Hematologic: Thrombocytopenia (as defined as < 80,000 platelets/ mm3
but >30,000 platelets/ mm3) or a 50% drop in the last 3 days
- Unexplained metabolic acidosis: pH < 7.30 with an elevated plasma lactate
level that is > 1.5 times the upper limit of normal
Exclusion Criteria
- Patients with surgery in the previous 12 hours
- Thrombocytopenia < 30,000 platelets/mm3
- Patient requiring therapeutic doses of heparin (> 15000 Units/day)
to treat a thrombotic condition within the previous 8 hours, LMWH at a dose
higher than prophylaxis within in the previous 12 hours
- Patients who have received systemic thrombolytic therapy within the past
3 days, ASA > 650 mg/day within the past 3 days, Glycoprotein IIb/IIIa
antagonists within the past 7 days, warfarin within the past 4 days, or clopidogrel
or ticlopidine within the past 4 days
- INR >3 or aPTT>100 seconds
- Evidence of post-operative bleeding
- Evidence of active and clinically significant gastrointestinal bleeding
- Patients with a central nervous system mass lesion, stroke within 3 months,
history of AVM, cerebral aneurysm, intracranial surgery, or history of severe
head trauma requiring hospitalization
- Patients with cirrhosis (history of esophageal varicies, portal hypertension,
or Child's Class C)
- Patients with a new nephrostomy tube or evidence of a bleeding complication
following a percutaneous procedure, e.g.:
a)Decreasing Hgb
b)Flank hematoma after femoral line placement
- Patients with unexplained mental status changes or neurologic exam changes
in whom a CT scan has not been performed to rule out a mass lesion or CNS
bleed
- Patients with end-stage disease processes in which there is not a commitment
to aggressive management of the patient
- Patients enrolled in a clinical trial involving a molecule that targets
the coagulation cascade
- Patients with pulmonary, splenic or liver contusions following trauma
- Patients with an epidural catheter in place within 12 hours of initiation
of therapy w rhAPC
- Pediatric patients only with approval of Pediatric Infectious Disease or
unless treating purpura fulminans
Guidelines for Monitoring rhAPC Use
- rhAPC should be dosed based on patient ideal body weight
a)for males:50Kg + 2.3Kg for every inch in height over 5 feet
b)for females:45Kg + 2.3Kg for every inch of height over 5 feet
c)for patients weighing less than ideal body weight, actual weight should
be used
- Patients should be given 24 mcg/kg/hr of rhAPC as a continuous infusion
for 96 hours.
- If a surgery or percutaneous procedure or epidural catheter needs to be
performed, rhAPC should be stopped 2 hours prior to the procedure.
rhAPC can be restarted 1 hour after a percutaneous procedure and 12 hours
after a surgical procedure, lumbar puncture or epidural catheter removal if
adequate hemostasis has been achieved.
- If evidence of GI bleeding occurs, rhAPC should be stopped and the cause
of the bleeding investigated
- Patients receiving rhAPC should be on some form of gastroprotective agent
such as sucralfate, a histamine-2 antagonist, or a proton-pump inhibitor.
- If a patient requires full-dose therapeutic heparin for the treatment of
a thrombotic event, the rhAPC infusion should be stopped.
- If a patient requires renal replacement therapy, attempts should be made
to run the dialysis with rhAPC alone, if clotting occurs, the lowest dose
of heparin necessary to maintain the patency of the dialysis filter should
be used.
Approval Process
- rhAPC is NOT a STAT agent.
- Orders for rhAPC received in the pharmacy between 10 pm and 7 am will be
dealt with after 7 am (except in the case of meningococcal infections).
- The pharmacist will review the review the case for eligibility. In all cases,
Infectious Disease consultation is required to ensure appropriate antibiotic
coverage during rhAPC use. In the event the patient is deemed ineligible,
and the attending physician of record wishes to proceed, the case will be
brought to one of the prenamed intensivist sponsors for adjudication
- Routine review of the appropriate use of this agent will be performed
