[Frequency of anaemia and indications for treatment with epoetin in chronic renal failure at the pre-dialysis stage].

Objectives: To determine the degree of anaemia corresponding to the decreasing levels of renal function in patients with chronic renal failure (CRF) and not yet on dialysis, and to assess the indications for treatment with recombinant erythropoeitin (epoetin).

Methods: We studied the relationship between haemoglobin (Hb) concentration and creatinine clearance (Ccr) in 403 consecutive patients with CRF regularly monitored in nephrology consultations between January 1 and June 30, 1999, and who received appropriate iron and vitamin supplementation. These patients were then followed-up until June 30, 2000 or until maintenance dialysis was initiated.

Incidence of anaemia, and use of epoetin therapy in pre-dialysis patients: a prospective study in 403 patients.

Background: Recent American and European guidelines recommend that epoetin therapy should be considered whenever the blood haemoglobin (Hb) level is <10-11 g/dl in dialysis patients and in pre-dialysis patients. Thus, data on the current prevalence of anaemia with respect to the degree of chronic renal insufficiency are needed in order to determine the potential indications of epoetin therapy in the pre-dialysis period.

Methods: We prospectively studied 403 consecutive ambulatory pre-dialysis patients whose serum creatinine (Scr) was 200 micro mol/l or more at their first passage at our out-patient clinic between January 1 and June 30, 1999.
