[Plasma ceruloplasmin in patients with hepatorenal insufficiency].

Changes in plasma ceruloplasmin levels were studied by enzyme immunoassay in 81 patients with the acute hepatorenal insufficiency syndrome (AHIS). Changed plasma ceruloplasmin concentration was detected in the first days of the disease, this change depending on AHIS severity and unrelated to the disease cause. A lowering of plasma ceruloplasmin level below 0.75 mg/ml is considered to be a poor prognostic sign. Measurement of plasma ceruloplasmin is a test available for clinical laboratories, it is highly sensitive, accurate, and reproducible.
