ACE inhibitors do not induce recombinant human erythropoietin resistance in hemodialysis patients.
Angiotensin-converting enzyme (ACE) inhibitors may exacerbate anemia in patients with chronic renal failure, as well as in dialysis patients. To better answer this question, a prospective, crossover study was conducted to evaluate the effect of ACE inhibitors on recombinant human erythropoietin (rHuEPO) requirements in hemodialysis patients. Patients administered an ACE inhibitor when entering the study remained on this drug for the initial 4 months and were then switched to another antihypertensive agent for 4 more months. Patients not initially administered an ACE inhibitor were switched to lisinopril at 4 months. rHuEPO doses were adjusted using a sliding scale based on weekly laboratory hematocrit values. The inclusion criteria were met by 51 patients undergoing dialysis. Demographics were as follows: 61% were women, 64% were black, 46% had diabetes, average age was 53.2 +/- 13.3 years, and time on hemodialysis was 38.0 +/- 44.5 months. Thirty-three patients completed the study. Hematocrit averaged 32.7% +/- 1.9% while on ACE inhibitor therapy and 33.1% +/- 2.1% off ACE inhibitor therapy (P = 0.217). There was no difference in rHuEPO dose per treatment during each period (3,500 +/- 1,549 U on ACE inhibitor therapy versus 3,312 +/- 1,492 U off ACE inhibitor therapy; P = 0.300). No significant differences were found in degree of blood pressure control or various clinical and laboratory parameters that might be associated with rHuEPO resistance between the two periods. Similarly, no differences were found in hospitalization days, duration of infections, or transfusion requirements. These findings suggest that ACE inhibitors do not contribute to rHuEPO resistance in hemodialysis patients.

Lisinopril pharmacokinetics and erythropoietin requirement in haemodialysis patients.
There is ongoing controversy whether angiotensin-converting enzyme inhibitors (ACE-I) contribute to anaemia by causing hyporesponsiveness to erythropoiesis-stimulating agents (ESA). However, it is unknown whether or not plasma levels or area under the curve (AUC) of ACE-I are associated with responsiveness to ESA therapy.. We examined the association between lisinopril AUC, lisinopril plasma levels and ESA requirements that was assessed using an ESA index [(ESA IU/week/body weight kg)/(haemoglobin g/dL)]. After screening 184 haemodialysis patients, 14 fulfilled the inclusion criteria, mainly long-term use of oral lisinopril in the upper end of dosage range for this population with stable haemoglobin levels and intravenous ESA therapy. Lisinopril plasma levels were measured at eight different time points (predialysis, immediate post-dialysis and hourly for 6h thereafter; AUC1), and the seven post-dialysis lisinopril plasma levels were used for calculation of AUC2.. The mean ESA index of all patients was 27·90±25·84 (IU/week/kg)/(g/dL). Average lisinopril AUC1 was 1212·48±1209·75 [mg*h/L], whereas AUC2 averaged 947·67±977·07 [mg*h/L]. Two patients (14%) had no detectable lisinopril plasma levels, indicating their noncompliance. There was no association between ESA index and AUC or plasma levels of lisinopril at any time point for all 14 or for the 12 compliant patients.. Our study shows that long-term, high-dose lisinopril therapy has no effect on ESA responsiveness. Thus, avoidance or a dose reduction of ACE-I in dialysis patients will not necessarily lead to reduced ESA requirements and costs.

Progression of renal failure with anaemia and multiple effects of angiotensin-converting enzyme inhibitor in rats with renal mass reduction.
Several factors such as proteinuria and renal fibrosis may be important in the progression of many forms of chronic renal diseases. The purposes of the current study were to investigate the progressive renal failure of the rats with surgical renal mass reduction (RMR) and the effect of the angiotensin-converting enzyme (ACE) inhibitor, lisinopril, and to document correlation of several factors associated with progressive renal failure. Rats were subtotal (5/6) nephrectomized by resection of the renal poles and sham-operated. The functional, histological and haematological changes of the rats were studied for up to 10 weeks. After 2 weeks of RMR, oral administration of lisinopril (10 mg kg(-1) per day) was performed for 8 weeks. RMR resulted in progressive renal failure with proteinuria, monocyte/macrophage (ED1+) infiltration, anaemia as assessed by haemoglobin and haematocrit (Htc), renal hypertrophy as assessed by left kidney to body weight ratio (BKW/BW), and renal fibrosis as assessed by glomerular lesions and tubulointerstitial changes. Lisinopril exhibited renoprotection with antiproteinuric effect and inhibition of monocyte/macrophage (ED1+) infiltration. However, beneficial effect of lisinopril on anaemia was not observed. At 10 weeks after surgery, severity of proteinuria positively correlated with plasma creatinine (Pcr), BKW/BW, histological damage, and systolic blood pressure, and negatively correlated with haemoglobin. Severity of tubulointerstitial changes positively correlated with Pcr and blood urea nitrogen, and negatively correlated with haemoglobin and Htc. Moreover, monocyte/macrophage (ED1+) infiltration positively correlated with severity of proteinuria and tubulointerstitial changes. These findings strongly support that proteinuria, monocyte/macrophage infiltration and renal fibrosis appear to play principal roles in the progressive renal failure with anaemia and renoprotection of ACE inhibition may be mediated by multiple actions of ACE inhibitor. The present study confirms that rats with RMR is useful to explore target molecules for renoprotective drugs and evaluate renoprotective effect of new molecular entities.
