Erythropoietin levels during theophylline treatment in premature infants.
Mean erythropoietin levels were somewhat higher in premature infants receiving theophylline than in untreated infants with a comparable degree of anemia. These results differ from those in adults and may reflect the oxygenation of the theophylline-treated patients or the developmental regulation of erythropoietin production in response to adenosine receptor antagonists.
