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.

Objective To explore the safety and efficacy of intravenous (IV) iron sucrose in maintenance peritoneal dialysis (PD). Design Randomized, controlled, parallel-group single-center trial. Setting Blood Purification Center of Chaoyang, Beijing Capital University of Medical Science, China. Methods 46 patients on PD were involved in this trial. 26 patients received IV iron sucrose (200 mg iron) once per week for 4 weeks then once every other week for a further 4 weeks. The other 20 patients received oral ferrous succinate, 200 mg three times per day, for 8 weeks. Hemoglobin, hematocrit, serum ferritin (SF) level, and transferrin saturation (TSAT) were assessed at baseline and then again after 2, 4, and 8 weeks of treatment. Results There were no differences between the IV and oral groups in terms of sex, age, duration of PD, mean dialysate dosage per day, erythropoietin dosage per week, or hematological parameters at baseline. After 4 and 8 weeks of treatment, mean Hb and Hct were significantly increased in the IV group and were also significantly higher than those in the oral group. Levels of SF and TSAT were also significantly increased in the IV group, and significantly higher than in the oral group. After 8 weeks, the response rate in the IV group was 94.8%, which was significantly higher than that in the oral group. The mean erythropoietin dose was significantly lower in the IV group than in the oral group. Hb, Hct, SF, and TSAT levels were maintained between 4 and 8 weeks in the IV group despite the decrease in dose frequency. There were no adverse events with IV iron. Eight patients in the oral group had adverse gastrointestinal effects. Conclusion IV iron sucrose is safe in PD patients. It increases Hb levels and serum iron parameters more effectively than oral iron; it is well tolerated and can permit reductions in the required dose of erythropoietin.

Intravenous Iron Supplementation

The vast majority of erythropoietin (EPO)–treated peritoneal dialysis (PD) patients require iron supplementation. Most authors and clinical practice guidelines recommend primary oral iron supplementation in PD patients because it is more practical and less expensive. However, numerous studies have clearly demonstrated that oral iron therapy is unable to maintain EPO-treated PD patients in positive iron balance. Once patients become iron-deficient, intravenous iron administration has been found to more effectively augment iron stores and hematologic response than does oral therapy. We recently performed a prospective, cross-over trial in 28 iron-replete PD patients and showed that twice-monthly outpatient iron polymaltose infusions (200 mg) were a practical and safe alternative to oral iron. That treatment produced significant increases in hemoglobin concentration and body iron stores. The additional expense of intravenous iron therapy was completely offset by reductions in EPO dosage. Careful monitoring of iron stores is important in patients receiving intravenous iron supplementation in view of epidemiologic links with infection and cardiovascular disease. Nevertheless, a growing body of evidence suggests that, as has been found for hemodialysis patients, intravenous iron therapy is superior to oral iron supplementation in EPO-treated PD patients.

The Impact

Iron deficiency anaemia (IDA) is a worldwide healthcare problem affecting approximately 25% of the global population. The most common IDA treatment is oral iron supplementation, which has been associated with gastrointestinal (GI) side effects such as constipation and bloating. These can result in treatment non-adherence and the persistence of IDA. Intravenous iron does not cause GI side effects, which may be due to the lack of exposure to the intestinal lumen. Luminal iron can cause changes to the gut microbiota, aiding the promotion of pathogenic species and decreasing beneficial protective species. Iron is vital for methanogenic archaea, which rely on iron for growth and metabolism. Increased intestinal methane has been associated with slowing of intestinal transit, constipation, and bloating. Here we explore the literature to understand a potential link between iron and methanogenesis as a novel way to understand the mechanism of oral iron supplementation induced GI side effects.

Background: Anemia is commonly observed in patients with chronic kidney disease (CKD) as soon as the glomerular filtration rate falls below than 30 ml/min. CKD patients frequently have iron deficiency. The use of both erythropoiesis-stimulating agents (ESA) and iron therapy is the backbone of anemia management in CKD. For this reason, an adequate iron supply is mandatory to achieve the optimal therapeutic benefit of erythropoiesis stimulating agents (ESAs). Many groups agree that anemia in peritoneal dialysis (PD) patients is less severe than in hemodialysis (HD) patients and that there are important differences in treatment practices for anemia between PD and HD patients. Methods: Analysis of the Anemia module of the French Language Peritoneal Dialysis Registry (RDPLF) register from the database set up in 2005 with a study of the period 2010-2017. Results: Data from 568 patients who participated in the Anemia module were analysed during the 2010-2017 follow-up period. Their median age were 71 years, 42% were female, median dialysis vintage was 13 months, 40,5% of patients had diabetes mellitus, 74% of patients were treated with ESA, 23% were on oral iron and only 11% have received intravenous iron. In terms of biological assessment, the average hemoglobin level was close to 12 g/dl and median CRP was close to 5 mg/l. For the iron balance, ferritin reached an average level of 270 µg/l in 2013 and stabilized in 2017 at 200 µg/l. The transferrin saturation coefficient always fluctuated between 23 % and 25 % from year 2010 to year 2017. Conclusion: The results of the Anemia module of RDPLF register appear to be in line with the target values of the ERA-EDTA latest European guideline on anemia (ERBP 2013) and show the low use of intravenous iron in PD (usually as second line therapy).

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.

Abstract Objectives Iron deficiency anemia (IDA) is a widespread nutritional deficiency. Iron supplementation with ferrous sulfate (FeSO4) is the most common strategy to treat IDA; however, the compliance with daily FeSO4 administration is poor, due to contraindicating side effects. Previously, we have reported that A. oryzae (Ultimine®; ULT) is a novel iron source. Therefore, the objective of this study was to determine the biochemical assessment, non-transferrin bound iron (NTBI) and commonly related gastrointestinal side effects to assess the safety of A. oryzae compared to FeSO4. Methods Female participants (n = 16) with serum ferritin concentrations 40 µg/L were randomized to a double-blind, 9-wk cross-over study with a 3-wk placebo washout period between treatments. Oral iron supplements (65 mg Fe), FeSO4 and ULT were administered for 21 consecutive days for each subject. Side effect questionnaires were collected 3d/wk over the 9-wk study period. Side effects and biochemical markers (nausea, heartburn, abdominal pain, fatigue, headache, diarrhea, constipation, oxidative stress and liver and kidney function) from iron supplementation were evaluated, along with serum iron, % transferrin saturation (TS) and NBTI 8 h curves. Results Serum iron, TS, and NTBI were all markedly higher with FeSO4 at each time-point from 2–8 hours (P < 0.001) compared to ULT, whereas NTBI was undetected. Among treatments, FeSO4 resulted in higher inflammation, though not statistically significant. Compliance based on returned pills was higher with ULT (97.3%) than placebo and FeSO4 (95.2% and 93.2%, respectively). Subjects taking FeSO4 reported abdominal discomfort 2% more than ULT, which was not significantly different. FeSO4 caused marginally higher incidence of combined nauseation, constipation and diarrhea when subjects were taking FeSO4 (P < 0.07). Iron status was maintained similarly by both oral iron supplements. Oxidative stress, inflammation, kidney and liver function markers were not elevated with ULT supplementation, suggesting safety of its consumption. Conclusions Better compliance and less gastrointestinal related side effects were reported with ULT compared to FeSO4, while maintaining normal iron status. Our data suggests ULT is a safe oral iron supplement for treatment of IDA. Funding Sources Cura Global Health, Inc.

Current iron supplementation practice in geriatric patients is erratic and lacks evidence-based recommendations. Despite potential benefits in this population, intravenous iron supplementation is often withheld due to concerns regarding pharmacy expense, perceived safety issues, and doubts regarding efficacy in elderly patients. This retrospective, observational cohort study aimed to evaluate the safety and efficacy of intravenous ferric carboxymaltose (FCM, Ferinject) in patients aged >75 years with iron deficiency anaemia (IDA). Within a twelve-month data extraction period, the charts of 405 hospitalised patients aged 65–101 years were retrospectively analysed for IDA, defined according to WHO criteria for anaemia (haemoglobin: <13.0 g/dL (m)/<12.0 g/dL (f)) in conjunction with transferrin saturation <20%. Of 128 IDA patients screened, 51 (39.8%) received intravenous iron. 38 patient charts were analysed. Mean cumulative dose of intravenous FCM was 784.4 ± 271.7 mg iron (1–3 infusions). 18 patients (47%) fulfilled treatment response criteria (≥1.0 g/dL increase in haemoglobin between baseline and hospital discharge). AEs were mild/moderate, most commonly transient increases of liver enzymes (n= 5/13.2%). AE incidence was comparable with that observed in patients <75 years. No serious AEs were observed. Ferric carboxymaltose was well tolerated and effective for correction of Hb levels and iron stores in this cohort of IDA patients aged over 75 years.

Background. The potential benefits of administering a dose of intravenous iron in patients with moderate postpartum anaemia rather than oral iron alone remains unproven.Aims.To determine whether a single injection of intravenous iron followed by a 6-week course of oral iron is as effective over 6 months in restoring normal haemoglobin levels and replenishing iron stores in women with moderate postpartum anaemia as a course of oral iron alone in women with mild postpartum anaemia.Materials and Methods. Retrospective two-arm cohort study in women with mild postpartum anaemia (haemoglobin 9.6–10.5 g/dL) prescribed iron daily for 6 weeks (N=150) and women with moderate postpartum anaemia (haemoglobin 8.5–9.5 g/dL), given a single 500 mg injection of intravenous iron followed by iron daily for 6 weeks (N=75). Haemoglobin and ferritin were measured 6 months postpartum.Results. Haemoglobin returned to similar mean levels in both groups. Ferritin levels were statistically significantly higher in the intravenous + oral group (57.7±49.3 μg/L versus32.9±20.1 μg/L).Conclusions.Despite lower baseline haemoglobin, intravenous iron carboxymaltose was superior to oral iron alone in replenishing iron stores in moderate postpartum anaemia and may prove similarly beneficial in mild postpartum anaemia.
