Anemia is a common feature of diabetes and chronic kidney disease (CKD) mainly due to erythropoietin (EPO) deficiency and uremic toxicity. Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) have been established as first-choice medications for the treatment of diabetic nephropathy. However, there are conflicting data regarding their impact on hemoglobin levels in patients with diabetic nephropathy. We evaluated the prevalence of anemia in 101 patients with diabetes mellitus type II and CKD at stage III-IV (group A) compared with 101 non-diabetic patients with similar renal function (group B). Moreover, we evaluated the impact of ACE inhibitors and ARBs on patients' anemia. Anemia was observed in 60 patients in group A and in 47 patients in group B (P < 0.01). Thirty-one (31) patients in group A and 19 patients in group B were receiving exogenous EPO for correction of renal anemia (P <0.05). Mean values of hemoglobin did not show significant differences (12.5 ± 1.8 vs 12.6 ± 1.7 g/dL) between the two groups. Seventy-five patients in group A and 52 patients in group B were receiving ACE inhibitors and/or ARBs (P <0.01), but, after multivariate analysis, we could not detect any association between anemia and the prescription of these medications. Anemia is more common in diabetic patients with CKD stage III-IV than in non-diabetic patients with similar renal function. Our results indicate that ACE inhibitors and ARBs are not a significant cause of anemia for both populations.
