title: [Evaluation of treatment of anemia with erythropoietin in patients with multiple myeloma].
abstract: Multiple myeloma is very frequently associated with anaemia which has the character of hypo-proliferative anaemia of chronic diseases. In this type of anaemia the erythropoietin formation is frequently inadequate. According to data in the literature pharmacological doses of erythropoietin lead to an increase of the haemoglobin concentration in blood. Erythropoietin (Eprex Cilag) was administered to 11 patients whose haemoglobin concentration was lower than 100 g/l. The results from 10 patients were finally evaluated. During the first month all patients were given erythropoietin - 150 U/kg three times per week. Unless during the first month of treatment the haemoglobin concentration increased by 10 g/l, the dose was doubled to 300 U/kg. In patients where the haemoglobin value had risen above 120 g/l, the authors assessed an individual maintenance dose. In case three-month erythropoietin treatment did not lead to an increase of haemoglobin by 20 g/l as compared with the baseline value, erythropoietin administration was discontinued. The haemoglobin concentration increased by 20 g/l in a total of 8 (80%) of 10 evaluated patients. In all five patients where the haemoglobin concentration increased by 20 g/l during the first month, the endogenous erythropoietin concentration was less than 60 U/l. In another three patients the mentioned therapeutic response was recorded only during the 2nd or 3rd month of treatment after the erythropoietin dose had been increased. These three patients had higher baseline concentrations of endogenous erythropoietin, 100 to 350 U/l. During treatment no undesirable effects of erythropoietin were observed. Erythropoietin is a useful drug for anaemic patients with the diagnosis of multiple myeloma. According to the results of the authors work and data in the literature it is obvious that in patients with endogenous serum erythropoietin below 100 U/l a rapid riae of haemoglobin can be observed already during the first month. Patients with a higher baseline concentration of endogenous erythropoietin (100 to 500 U/l) respond less frequently to treatment and larger doses of erythropoietin must be administered. In patients with an erythropoietin value above 500 U/l there is a minimal probability that a response will be produced.
