One hundred patients, 55 males and 45 females (age range 13-78 years) were divided into 2 groups. Group-I patients received rHuEPO and ACE inhibitors/ARBs while Group-II patients received rHuEPO with other antihypertensives such as calcium channel blockers or beta-adrenergic receptor blockers. Monthly increment in hematocrit (HCT%) was monitored in both groups for 4 continuous months. One-way ANOVA on Dunn's, univariate and multivariate analyses were carried out to determine any significant improvement in erythropoiesis between the 2 treatment groups.RESULTS: Monthly increase in HCT% was significantly greater in the group that was treated with rHuEPO and antihypertensives other than ACE inhibitors/ARBs compared with that treated with ACE inhibitors/ARBs, an effect observed even at a higher dose of rHuEPO, and the patients were iron replete.CONCLUSIONS: The present data from our population confirms that ACE inhibitors/ARBs interfere with rHuEPO therapy for treatment of anemia in CRF. The ACE inhibitors/ARBs inhibit erythropoiesis induced by rHuEPO in CRF patients, therefore, simultaneous use of ACE inhibitors/ARBs and rHuEPO should be carried out with caution.
