A normocytic normochromic anemia is one of the first signs of renal failure. Since anemia increases morbidity and mortality, its elimination is one of the essential objectives of the treatment. Human recombinant erythropoietin (rHuEPO) has changed the therapeutical approach to anemia. The aim of the present study was to compare efficacy of anemia correction in peritoneal dialysis patients depending on treatment and dialysis modality. The study is the retrospective analysis of 64 patients who presented to our Clinic in 2003. Eighteen (28.13%) patients were treated with rHuEPO, 14 (28%) underwent continuous ambulatory peritoneal dialysis (CAPD), 2 (100%) - automated peritoneal dialysis (APD) and 2 (33.3%) - intermittent peritoneal dialysis (IPD). Mean hemoglobin level was 98.6?17.82 g/l in patients treated with rHuEPO versus 98.81?15.14 g/I in patients without rHuEPO treatment. Erythropoietin requirements were 3392.85?1211.77 IU/week. AII patients received iron supplementation during rHuEPO therapy. Mean serum ferritin levels were 463.41 ?360 ?g/l. Transferrin saturation (TSAT) was 0.35?0.16%. No difference of serum iron and TSAT levels was found between CAPD and IPD patients. The degree of anemia significantly differed between CAPD and IPD patients. A total of 17.11% of PD patients were given blood transfusions, most frequently during the first three months after the onset of dialysis. Our conclusion is that the number of patients receiving rHuEPO should be increased, as 50% of our patients should be substituted, while only 28% are being treated. As 50% of patients receiving rHuEPO failed to reach target Hgb levels, higher EPO doses should be considered. Iron stores should be continuously monitored, particularly in patients receiving rHuEPO, since iron deficiency is an important problem for patients undergoing peritoneal dialysis, especially during erythropoietin therapy. Oral iron supplementation is satisfactory in the majority of patients, and iron-gluconate is absorbed better than iron-sulphate. If required, intra-venous iron bolus is safe and efficient. Continuous peritoneal dialysis treatment improves blood count more effectively compared to intermittent procedures, as hemoglobin levels are significantly higher in patients with comparable iron stores. Peritoneal dialysis is particularly efficient in improving the blood count in diabetics, since no significant difference of anemia between patients affected by diabetes mellitus and the others could be found in our study.

Intravenous Iron Therapy

Introduction. Normocytic, normochromic anemia is one of the first signs of chronic renal failure and it is common in patients on chronic dialysis treatment. It causes decrease in oxygen supply to tissues, increases cardiac minute volume, causes left ventricular hyperthrophy, cardiac insufficiency, disorders related to cognitive functions and immune response, and increases morbidity and mortality rates. The leading cause of anemia in patients on chronic peritoneal dialysis (PD) is iron depletion and most patients on PD need oral or parenteral iron supplementation. The aim of this study was to evaluate our first experience with bolus intravenous ferrogluconate therapy in patients on chronic peritoneal dialysis at the Nephrology Clinic of the Clinical Center of Serbia (CCS). Material and Methods. We examined 11 patients, 7 males and 4 females, mean-age 49 years (range 31 to 68 years) on chronic PD. All patients received blood transfusions, oral or intramuscular iron supplementation before 465 to 665 mg ferrogluconate therapy was given in 500 ml. saline intravenous infusion; 5 of them were on erythropoietin therapy and 2 of them started with EPO therapy after the ferrogluconate therapy. Results. The blood count improved during the first 3 months after application of bolus intravenous iron therapy (ferrogluconate); erythropoietin dose was not increased during the follow-up. Some patients suffered from side effects during infusion and 6 patients received the complete treatment. Discussion. Blood count improves in a number of patients affected by end-stage renal disease during the first months on continuous ambulatory peritoneal dialysis (CAPD) treatment. But a large number of patients on chronic CAPD treatment are iron-depleted and they require oral or parenteral substitution. Side effects and complications of intravenous iron therapy were not severe and only one patient suffered from allergic manifestations. Ferremia and blood count improved in patients who did not receive erythropoietin during the follow-up, and patients on erythropoietin therapy required lower doses after receiving the intraveonous iron therapy. Conclusion. Blood count improvement and the lack of severe side effects speak in favor of further iron supplementation with bolus intravenous iron replacement. .

In the treatment of anemia of chronic renal failure, the most common cause of recombinant human erythropoietin (rhEPO) resistance is iron deficiency. In peritoneal dialysis (PD) patients, oral iron therapy is an accepted and convenient method of iron supplementation. The effectiveness of oral iron, however, is limited by many factors, including gastrointestinal side effects and poor gastric absorption. This study prospectively compared the efficacy of single intravenous infusion of total dose iron (ITDI group) given in an outpatient setting with oral iron (oral group) for the treatment of anemia in PD patients. Twenty-five adult stable PD patients with baseline hematocrit 25 to 35% were entered into the study. Thirteen patients with serum transferrin saturation (TSAT) < 25% received ITDI, and 12 patients with TSAT between 25 and 35% received oral iron. One patient in the oral group received emergent blood transfusion and was excluded from analysis. Hematocrit and iron indices were measured at monthly intervals. Doses of rhEPO were adjusted monthly to maintain target hematocrit at 35%. At the end of the study (6 mo), despite similar baseline mean hematocrit (31.0 +/- 0.9 versus 33.0 +/- 1.0%), comparable mean baseline weekly rhEPO dose (7886 +/- 1449 versus 6370 +/- 1553 U/wk), and significantly lower level of mean TSAT (11.3 +/- 3.5 versus 30.1 +/- 3.5%; P < 0.05), the ITDI group when compared with the oral group had significantly higher mean hematocrit (36.0 +/- 1.0 versus 31.4 +/- 1.1%; P < 0.05) and TSAT (33.7 +/- 3.7 versus 22.6 +/- 4.0%; P < 0.05) values. In addition, the final mean dose of weekly rhEPO was significantly lower in the ITDI group (4799 +/- 981 versus 9998 +/- 1027 U/wk; P < 0.05). No patient in the ITDI group developed an adverse reaction to intravenous iron. It is concluded that ITDI represents a more efficacious method of iron supplementation in PD patients receiving rhEPO. Moreover, ITDI is safe and well tolerated and can be administered in an outpatient setting.

The clinical pharmacology of human recombinant erythropoietin (epoetin) was studied in order to compare the effectiveness of various routes and dosing schedules in dialysis patients. Thirty-six patients received epoetin beta three times a week i.v. for at least 12 wk. The mean dose needed to achieve target hemoglobin was 225 +/- 36 U/kg per week (median dose, 180 U/kg per week). Twenty-eight of 36 patients who were converted to a once-a-week i.v. schedule increased their requirements to 429 +/- 50 U/kg per week in order to maintain a target hematocrit of 33 to 40 vol%. Twelve of 28 patients could maintain their target hematocrit when dosed once a week s.c. at 84 +/- 10 U/kg. The other 16 patients required 137 +/- 15 U/kg per week divided into two doses. In the entire group of 28 patients, the weekly requirement for epoetin was reduced by 50% when the s.c. route was used two or three times a week. Pharmacokinetic studies performed during chronic therapy indicated rapid clearance of erythropoietin (t1/2 of 6.8 +/- 0.3 h). Single i.v. doses greater than 150 U/kg were required to increase basal erythropoietin by 30 mU/mL at 44 h postdosing. With s.c. dosing, such increments in erythropoietin levels frequently persisted beyond 60 h because of prolonged and slow absorption. Pharmacokinetic simulations in conjunction with clinical correlation of the erythropoietic response suggest that the duration that the erythropoietin levels are maintained, and not the absolute peaks, is the primary determinant of efficacy. This may result from nonlinearity in the dose response. Pharmacokinetic simulation also indicated that i.v. dosing could not maintain adequate interdialytic erythropoietin levels, whereas s.c. dosing could. Cost analysis indicated that the use of s.c. dosing two or three times a week at an average total weekly dose of 110 to 120 U/kg is effective treatment of anemia in most dialysis patients.

The total amount of iron available from normal body stores and usual dietary intake might be so small as to limit the rate and magnitude of the polycythemic response to high altitude. To evaluate this problem the influence of iron supplementation on blood hemoglobin concentrations was observed in ten members of a Himalayan expedition during the course of their ascent of a 25,660-ft peak. Half the group received iron supplements in large doses both orally and parenterally; the other five obtained only the iron present in the normal high altitude diet. Hemoglobin concentrations in both groups increased by 33% over 2 months. No significant difference in hemoglobin concentrations between the two groups was noted at any time during the course of the study. It is concluded that normal iron stores plus dietary iron were adequate to meet the needs of increased hemoglobin synthesis at high altitude in the five individuals who received no iron supplementation.

Abstract Background and Aims Transferrin saturation (TSAT) is an indicator of iron deficiency or overload, but its relationship with mortality in patients with different stages of chronic kidney disease (CKD) is unclear. We investigated the association of TSAT with mortality in CKD patients. Method In 479 CKD patients (97 CKD3-4 patients, 298 CKD5 non-dialysis patients and 84 peritoneal dialysis patients; median age 58 years, 67% males, 33% cardiovascular disease, CVD, and 29% diabetes), biomarkers of iron status (plasma iron, TSAT, transferrin and ferritin), systemic inflammation (high sensitivity C-reactive protein, hsCRP, and interleukin-6, IL-6) and nutritional status were assessed. During median follow-up of 35.6 months, 139 (29%) patients died, and 176 (37%) patients underwent renal transplantation. Patients were stratified into low (n=157) and high (n=322) TSAT tertile groups. All-cause and CVD mortality risk were analyzed with competing risk regression with renal transplantation as competing risk. Results TSAT [median 23% (IQR 17-30%)] was negatively associated with presence of DM and CVD, body mass index, hsCRP, IL-6, Framingham´s CVD risk score (FRS), erythropoietin resistance index (ERI) and iron supplementation, and positively associated with hemoglobin, ferritin and s-albumin. In competing risk analysis, low tertile of TSAT was independently associated with increased all-cause mortality risk (sHR=1.50, 95%CI 1.05-2.14) after adjusting for CKD stages, 1-SD of FRS, 1-SD of hemoglobin, 1-SD of hsCRP, 1-SD of ESA dose and iron supplementation (Figure 1). Conclusion TSAT was inversely associated with mortality risk in CKD patients. When evaluating clinical outcomes of CKD patients, iron status using TSAT as a predictive marker, should be considered.

A survey of the National CAPD Registry population was conducted to assess the distribution of hematocrit levels in a large group of peritoneal dialysis patients, to characterize the anemia of the population, and identify factors which relate to variation in hematocrit levels. A random sample of 812 patients was selected from the Registry population. Information was provided on 608 patients. Characteristics of sampled patients were similar to the Registry population as a whole. The mean hematocrit level in this cohort was 29.4% and the median was 29%. Recent peritonitis, time on CAPD, folate therapy, androgen therapy, and iron therapy had no obvious influence on hematocrit distributions. Significantly higher hematocrits were seen in males, whites, and patients with polycystic kidney disease. Significantly lower hematocrits were seen in surgically anephric patients and in patients who had received transfusions 60 days before the survey. Eighty-nine percent of patients had not received a transfusion 60 days prior to the survey. Some patients, especially those with hematocrits below the median, might benefit from recombinant erythropoietin therapy.

Background This study was conducted to evaluate the risk of developing acute pancreatitis (AP) and the fatality from AP in hemodialysis (HD) and peritoneal dialysis (PD) patients, using the claims data of Taiwan National Health Insurance. Methods From patients with newly diagnosed end-stage renal disease (ESRD) in 2000–2010, we identified a PD cohort ( N = 9,766), a HD cohort ( N = 18,841), and a control cohort ( N = 114,386) matched by sex, age, and the diagnosis year of the PD cohort. We also established another 2 cohorts with 9,744 PD patients and 9,744 propensity score-matched HD patients. The incident AP and fatality from AP were evaluated for all cohorts by the end of 2011. Results The adjusted hazard ratios (HRs) of acute pancreatitis were 5.68 (95% confidence interval [CI] = 5.05 – 6.39), 4.91 (95% CI = 4.32 – 5.59), and 7.47 (95% CI = 6.48 – 8.62) in the all dialysis, HD, and PD patients, compared with the controls, respectively. Peritoneal dialysis patients had an adjusted HR of 1.41 (95% CI = 1.21 – 1.65) for AP, compared with propensity score-matched HD patients. Peritoneal dialysis patients under icodextrin treatment had a lower incidence of AP than those without the treatment, with an adjusted HR of 0.59 (95% CI = 0.47 – 0.73). There was no significant difference in the 30-day mortality from AP between HD and PD patients. Conclusions Peritoneal dialysis patients were at a higher risk of developing AP than HD patients. Icodextrin solution could reduce the risk of developing AP in PD patients.

Payment Schemes

Background Cost is always a big issue for dialysis patients. In the present study, we analyzed the effect of different payment schemes on dialysis adequacy and clinical outcome in our peritoneal dialysis program. Methods This is a single-center cohort study. A total of 175 patients who began dialysis from January 2006 to December 2007 were included. Baseline data, including volume status, dietary intake and nutrition status, dialysis adequacy, and sodium removal were collected at 6 months after peritoneal dialysis. Based on the different payment schemes, the patients were divided into 2 groups, higher payment group (GHP, 130 cases, with more than 85% reimbursement), and lower payment group (GLP, 45 cases, with less than 50% payment or totally self-paid). Patients were followed up until dropout or until December 31, 2013. Results At baseline, patients in the 2 groups had nearly the same residual renal function. But the GLP group patients dialyzed at a lower dose (4,516.91 ± 1,768.20 mL vs 6,058.17 ± 2,013.43 mL, p < 0.001). They had lower creatinine clearance (51.64 ± 24.23 L/w vs 70.54 ± 30.27 L/w, p < 0.001), sodium removal (2.23 ± 1.29 g vs 2.77 ± 1.29 g, p = 0.027), and fluid removal (970.33 ± 545.97 mL vs 1,146.66 ± 460.93 mL, p = 0.038). Normalized by height (in meters), the GLP group patients still had a lower normalized dialysis dose (2,890.61 ± 1084.44 mL/m vs 3,761.34 ± 1,237.10 mL/m, p < 0.001). Baseline nutritional and dietary parameters were comparable except that a lower daily protein intake (42.73 ± 10.99 g vs 47.26 ± 14.30 g, p = 0.032) and higher serum urea level (23.43 ± 6.88 mmol/L vs 19.84 ± 5.92 mmol/L, p < 0.001) were presented in the GLP group. There was no difference in volume status. During the follow-up, Kaplan-Meier analysis showed that there was no significant difference in patient survival and technique survival. In multivariate Cox regression analysis, after adjusting for related factors, payment was again not a strong predictor of survival in the study population. Conclusion Our study found that GLP group patients were adherent to lifestyle modification with lower dialysis doses, and they also had nearly the same long-term clinical outcome as the GHP group patients. Thus, lower dialysis doses combined with controlled dietary intake may be an effective approach to solve the dialysis problem for the low socio-economic status (SES) population.
