About

CASTRO1 is a study to investigate the reduction of C-reactive protein (CRP) by therapeutic apheresis (CRP-apheresis) in patients after primary treatment of ischemic stroke.

The term therapeutic apheresis commonly refers to medical procedures, where pathogenic constituents are being removed from the circulating blood. Elimination is performed by adsorbers outside the body in an extracorporeal circulation. For removal of the pathogenic substances the plasma is separated from the blood (circulation) to pass the adsorber. The purified plasma is merged with the solid blood components thereafter and returned to the patient.

The adsorber "PentraSorb® CRP" used for CRP apheresis is CE-certified. It is designated to the selective depletion of C-reactive protein from human blood.

Full description

The purpose of the study is to evaluate the safety and efficacy of CRP apheresis in patients following ischemic stroke. CRP apheresis is to be conducted with the aim of reducing cerebral damage following the guideline-appropriate primary therapy of ischemic stroke.

A possible protective effect of CRP apheresis will be assessed by clinical scores, laboratory determination of immunologic parameters and determination of the size of the infarct area by magnetic resonance imaging (MRI).

The study will be randomized, controlled and monocentric.

Inclusion criteria

3 participants in 2 patient groups

Apheresis group
Experimental group
Description:
10 patients receive a maximum of 3 apheresis treatments at intervals of 24 ± 12 hours each (from the beginning of the preceding treatment). The first treatment starts within 72 hours after infarction or, in case of an unclear time window, within presumed 72 hours after the patient was last seen free of symptoms. No further treatments are carried out if the CRP concentration before the start of a treatment is \<10 mg/l or if the patient has been discharged from hospital. For each treatment, 1.5 - 2.5 times the plasma volume is processed. The duration of each treatment is approximately 4-6 hours.
Treatment:
Device: CRP apheresis
Control group
No Intervention group
Description:
10 patients of the control group receive the same examinations as arm 1 (verum group) but no apheresis treatments after ischemic stroke.
