BACKGROUND: A mild anaemia is often found in patients with congestive heart failure (CHF), but its significance is uncertain. In an open uncontrolled study we investigated the effect of correcting this anaemia [haemoglobin (Hb) 9.5-11.5 g%] with subcutaneous (s.c.) erythropoietin (Epo) and intravenous (i.v.) iron (Fe) in 179 patients, 84 type II diabetics and 95 non-diabetics, with moderate to severe CHF which was resistant to maximally tolerated doses of standard CHF medications. METHODS: Epo, s.c., was given every 1-3 weeks to achieve and maintain the Hb at 12.5 g%. Fe (Fe sucrose-Venofer) was added i.v. as necessary to maintain the Fe stores. Duration of treatment was 11.8 + 8.2 months. RESULTS: With the Epo-Fe treatment the Hb increased from 10.41 +/- 1.0 to 13.1 +/- 1.3 g% in diabetics and from 10.5 +/- 1.0 to 12.9 +/- 1.2 g% in non-diabetics. Comparing the diabetics and non-diabetics, the New York Heart Association functional class improved by 34.8 and 32.4%, respectively. breathlessness and/or fatigue, as measured by a self-administered Visual Analogue Scale, improved by 69.7 and 67.4%, and the left ventricular ejection fraction improved by 7.4 and 11.5%, respectively. The number of hospitalizations fell by 96.4 and 95.3%, respectively, compared with the pre-treatment period. Although the glomerular filtration rate (GFR) was falling at a rate of approximately 1 ml/min/month before the study in both groups, neither the mean serum creatinine nor the GFR changed significantly during the study period. The mean dose of Epo needed, measured in IU/week/kg body weight, was similar in the two groups. CONCLUSION: The correction of the mild anaemia that was found in diabetics and non-diabetics with resistant CHF and mild to moderate chronic renal failure improved the cardiac function and patient functional status, stabilized the renal function and markedly reduced the need for hospitalization.
