E.5 End points |
E.5.1 | Primary end point(s) |
Primary evaluation criteria will be the duration in days of extrarenal epuration |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Safety of ECZ injections. Adverse reactions of ECZ
Duration of ARF will be evaluated as follow: urine output measurement, GFR estimated with the Schwartz 2009 assay (based on creatinin plasma levels), ionogram, proteinuria.
Renal sequels will be evaluated at 1, 6 and 12 months after last injection of ECZ: blood pressure, GFR, ionogram, proteinuria and microalbuminuria.
Hematological abnormalities will be evaluated as follow:
• Duration of the thrombocytopenia
• Duration of the hemolytic anemia
Blood parameters of CAP will be evaluated with plasmatic dosages of the complement components C3 and CD46.
Inhibition of the TCC will be evaluated trough the CH50 assay and plasmatic free ECZ levels.
Incidence of extrarenal manifestations:
• Neurological involvement (seizures, coma, focal deficit)
• Cardiac involvement (cardiac failure, ischemic myocarditis, conduction or rhythm troubles)
• Digestive involvement (pancreatitis, hepatitis, hemorrhagic colitis, bowel perforation, rectal prolapsus)
