Use of intravenous iron in patients with iron deficiency and chronic heart failure: Real-world evidence

Introduction and objectivesTreatment with intravenous iron in patients with heart failure (HF) and iron deficiency (ID) improves symptoms, however its impact on survival and safety is unknown. We aimed to evaluate the management of ID and anemia with intravenous iron in patients with HF and long-term safety of intravenous iron.MethodsWe evaluated anemia and ID in patients with chronic HF at 3 university hospitals. Anemia was defined using the World Health Organization definition and ID was defined as ferritin <100 ug/L or a Transferrin Saturation <20% if ferritin between 100 and 299 ug/L. We assessed treatment with intravenous iron during follow-up and its association with mortality and HF hospitalizations using multivariate cox regression analysis.ResultsWe included 2,114 patients, median age 72 years and 57% had reduced left ventricular ejection fraction. ID was present in 55% and ID and anemia in 29%. Treatment with intravenous iron was used in 24% of patients with ID and 34% of patients with ID and anemia. In patients with ID, after multivariate adjustment, treatment with intravenous iron was associated with lower all-cause mortality: HR = 0.38 (0.28–0.56), lower cardiovascular mortality: HR = 0.34 (0.20–0.57) and no differences in HF hospitalizations: HR = 1.15 (0.88–1.50). Similar outcomes were found for patients with anemia and ID.ConclusionsIn a real-world cohort of patients with HF, treatment with intravenous iron was used in one third of patients with ID and anemia and appears safe in mid-term follow-up.     

Comparative analysis of iron status and other hematological parameters in preeclampsia†

Objective: To compare serum ferritin (SF) concentrations and other hematological parameters between patients with preeclampsia (PE) and normal pregnant women of the same gestational period who received supplemental iron during pregnancy.

Methods: Prospective, comparative, observational pilot study that included 31 women with PE and 30 healthy pregnant women, at 20 weeks’ of gestation. Ferritin, iron and complete blood cell count were compared between groups.

Results: In comparison with controls, preeclamptic patients had a higher weight, body mass index, and arterial pressure. Serum ferritin and serum iron were higher in patients with PE (median: 36.5?μg/l vs. 20.9?μg/l and 103.9?μg/dl vs. 90.8?μg/dl) with a significant difference (P?=?0.019 and P?=?0.345). SF values >40?μg/l correlated with PE (r?=?0.281; P?=?0.032). A platelet count less than 100?×?10⁹/l was higher in the PE group than in the control group (13% vs. 3%, P?=?0.354).

Conclusion: Higher SF levels, despite being within normal range, were associated with PE. The incidence of thrombocytopenia was higher in preeclamptic women, however, the remaining hematological parameters were similar in both groups.     

Increased iron absorption in patients with chronic heart failure and iron deficiency

BackgroundIron deficiency (ID) is common in patients with chronic heart failure (CHF), but the underlying causes are not fully understood. We investigated whether ID is associated with decreased iron absorption in patients with CHF.Methods and ResultsWe performed an oral iron-absorption test in 30 patients and 12 controls. The patients had CHF with reduced (n = 15) or preserved (n = 15) ejection fraction and ID, defined as s-ferritin < 100 µg/L, or s-ferritin 100–299 µg/L and transferrin saturation < 20%. The controls had no HF or ID and were of similar age and gender. Blood samples were taken before and 2 hours after ingestion of 100 mg ferroglycin sulphate. The primary endpoint was the delta plasma iron at 2 hours. The delta plasma iron was higher in the group with HF than in the control group (median increase 83.8 [61.5;128.5] µg/dL in HF vs 47.5 [30.7;61.5] µg/dL in controls, P = 0.001), indicating increased iron absorption. There was no significant difference between the groups with preserved or reduced ejection fraction (P = 0.46).ConclusionWe found increased iron absorption in patients with CHF and ID compared to controls without ID and HF, indicating that reduced iron absorption is not a primary cause of the high prevalence of ID in patients with CHF.Clinical Trial RegistrationEudraCT 2017-000158-21     

Intravenous iron supplementation may be superior to observation in acute isovolemic anemia after gastrectomy for cancer

AIM:To determine whether the application of postoperative intravenous(IV)-iron for acute isovolemic anemia after gastrectomy for cancer may be effective.METHODS:Among 2078 gastric cancer patients who underwent surgery between February 2007 and August2009 at the National Cancer Center Korea,368 patients developed post-operative anemia[hemoglobin-(Hb)-level<9 g/dL]within the first postoperative week.Patients requiring transfusions were excluded.IV-iron was administered to 63 patients(iron group).Sixty patients were observed without treatment(observation group).The clinical outcomes of the groups were compared concerning clinicopathologic data,morbidity,and changes in Hb levels using Fisher’s exact test,Student’s t-test and the Z-test.RESULTS:The initial Hb level was higher in the iron group than in the observation group(7.3±1.0 g/dL vs8.4±0.5 g/dL,P<0.001).The slope of the changes in the Hb level was significantly higher in the iron group than in the observation group(0.648±0.054 vs 0.349±0.038,P<0.001).The Hb level 1 and 3 mo postoperatively increased from 10.7±1.3 to 11.9±1.3g/dL in the iron group(P=0.033)and from 10.1±1.0to 10.8±1.4 g/dL in the observation group(P<0.001).The postoperative hospital stay was significantly longer in the iron group than in the observation group(10.5±6.8 d vs 7.6±5.5 d,P=0.011).There were no significant differences in the major and surgical complications between the groups(6.3%vs 13.3%,P=0.192;9.5%vs 3.3%,P=0.164).CONCLUSION:IV-iron supplementation may be an effective treatment for post-operative isovolemic postgastrectomy anemia and may be a better alternative than observation.     

Prevalence of iron deficiency anemia and iron deficiency in a pediatric population with inflammatory bowel disease

Objectives: Iron deficiency is the most common cause of anemia in children with inflammatory bowel disease, although the real prevalence is unknown. Intravenous iron is suggested as the first line treatment. This study aims to determine the prevalence of iron deficiency anemia in children with inflammatory bowel disease followed in a Pediatric Gastroenterology Unit of a tertiary center and to evaluate this unit's experience with intravenous iron.

Materials and methods: A retrospective cohort study was designed involving children with inflammatory bowel disease followed in that unit between January 2001 and April 2016. Laboratory results were collected at the moment of diagnosis, after one-year follow-up and prior each IV iron administration performed during the study period. Anemia was defined according to World Health Organization criteria and the iron deficiency was defined using recent guidelines.

Results: Were studied 69 patients 71% had CD and 29% UC. 50.7% were female. Mean patient age at diagnosis was 13.3 years (range 1--17 years). Prevalence of ID and IDA at diagnosis was 76.8% and 43.5%, respectively. After one year follow-up, those values decreased to 68.1% (p?=?.182) and 21.7% (p?=?.002), respectively. Hemoglobin significantly increased (p?<?.001). Intravenous iron was administered to 92.8% of patients. No adverse reactions were reported.

Conclusions: Intravenous iron is the first line in the treatment of Iron deficiency anemia in Inflammatory Bowel disease and it is safe and effective. Persistent anemia and iron deficiency are common.     

Treatment with Noripurum EV® is effective and safe in pediatric patients with inflammatory bowel disease and iron deficiency anemia

Objectives: To evaluate the therapeutic response and adverse effects of Noripurum EV^® in children and adolescents with inflammatory bowel disease (IBD) and iron deficiency anemia.

Materials and methods: Cohort study involving patients with Crohn’s disease (CD) and ulcerative colitis (UC) who received treatment for iron deficiency anemia with Noripurum EV^®. Anemia was defined according to WHO 2011 criteria. Iron deficiency anemia was established when ferritin <30µg/l and transferrin saturation <16%. Iron deficiency anemia and anemia of chronic disease were established when ferritin was between 30 and 100µg/l and transferrin saturation <16%. The total dose of Noripurum EV^® was estimated by the Ganzoni formula and divided into weekly administrations. When there was an increase in hemoglobin (Hb) by a minimum of 2g/dl and or when Hb reached the target determined by WHO, treatment was considered a therapeutic success.

Results: Noripurum EV^® was administered to 16 patients (9.3% of total patients with IBD). Ten (65.5%) were male, the mean (SD) age was 11.3(4.6) years old, 75%(12/16) had CD and 25%(4/16) had UC. All patients presented an increase in Hb (p?<?.001) at a mean (SD) of 2.8(1.3)g/dl, after median and interquartile range(IQR) of 4.5(3.0–6.0) weeks that iron infusions were completed. It was found that the proportion of patients that achieved therapeutic success (68.8%) was statistically higher (p?=?.031) than those who did not (31.2%). No adverse events were reported.

Conclusion: Noripurum EV^® in pediatric patients with IBD and iron deficiency anemia was effective and safe, making it an appropriate option for the clinical management of these patients.     

Inflammatory bowel disease and anemia: intravenous iron treatment

Objectives: The main objective of our study was to determinate the effectiveness of intravenous iron treatment with ferric carboxymaltose in inflammatory bowel disease (IBD) patients. Our other objectives were to study parameters that would predict a good response to the treatment and to chart out possible side-effects of the treatment.

Materials and methods: In our retrospective chart review study we collected clinical data and laboratory results related to IBD from medical records of 87 IBD patients who were treated with ferric carboxymaltose in Helsinki University Hospital between 2014 and 2016.

Results: The mean increase in hemoglobin levels of the patients was 24.6?g/l (+?24%) after one month, 27.6?g/l (+?27%) after three months and 26.0?g/l (+?27%) after six months. Nine out of 87 treated patients (10.3%) reported side-effects during the iron infusion. A linear regression model assessing the change in hemoglobin levels after six months demonstrated close correlation with transferrin receptor count (p?=?.004) and ferritin (p?=?.016) with an adjusted R square of 0.463.

Conclusion: Ferric carboxymaltose was found to be an effective and well tolerated treatment for iron deficiency anemia in patients with IBD. The results of our study further strengthen the current knowledge of the effectiveness and safety of the treatment.     

High-dose fast infusion of parenteral iron isomaltoside is efficacious in inflammatory bowel disease patients with iron-deficiency anaemia without profound changes in phosphate or fibroblast growth factor 23

Objective: Iron isomaltoside (Monofer^®) is a high-dose intravenous iron preparation with good tolerability and efficacy in inflammatory bowel disease (IBD) patients with iron deficiency anaemia (IDA). This trial evaluates the safety and efficacy, including effect on intact fibroblast growth factor 23 (iFGF23) of a high single dose and cumulative doses of iron isomaltoside in IBD patients with IDA.

Materials and methods: The trial was a prospective, open-label, multi-centre trial conducted in IBD patients with IDA. Based upon haemoglobin (Hb) levels at baseline and weight, the patients received 1500, 2000, 2500 or 3000?mg of iron isomaltoside infused in single doses up to 2000?mg. The outcome measurements included adverse drug reactions (ADRs) and changes in haematology and biochemistry parameters.

Results: Twenty-one IBD patients with IDA were enrolled, receiving 1500 (seven patients), 2000 (eight patients), 2500?mg (four patients) or 3000 (two patients) mg of iron. No serious ADRs were observed. Four patients experienced nine mild to moderate ADRs (hypersensitivity, pyrexia, vomiting, constipation, abdominal pain, dyspepsia (two events) and eye allergy (two events)). In total, 15 (75%) patients had an increase in Hb of ≥2.0?g/dL during the trial, with normalisation of ferritin. No changes in iFGF23 or clinically significant hypophosphataemia were found.

Conclusion: Rapid infusions of high-dose iron isomaltoside, administered as single doses up to 2000?mg and cumulative doses up to 3000?mg, were without safety concerns and were efficacious in increasing Hb levels in IBD patients. Iron isomaltoside did not induce profound phosphate wasting via increased iFGF23 levels.     

The impact of timing of intravenous iron supplementation on preoperative haemoglobin in patients scheduled for major surgery

BackgroundAnaemia is frequent and an independent risk factor for morbidity and mortality in patients undergoing surgery. Iron deficiency (ID) is the main cause for anaemia and can be corrected by intravenous (IV) iron. The aim of this study was to investigate the timing of preoperative IV iron supplementation on preoperative haemoglobin (Hb) level.Materials and methodsSurgical patients were screened for the presence of anaemia and ID from November 2015 to January 2020. In case of ID or iron deficiency anaemia (IDA), patients received IV iron supplementation. The timing of IV iron supplementation on preoperative Hb level was analysed by days and time frames clustered by 5 days before surgery.ResultsIn total, 404 patients with IV iron supplementation were analysed. In all patients, IV iron was administered with a median (interquartile range [IQR]) of 3.0 (1.0; 9.0) days before surgery. Preoperative Hb level increased steadily starting from 6 days (0.13 [±1.2] g/dL) until 16 days before surgery (1.75 [±1.1] g/dL). Group comparison revealed a median preoperative Hb change of −0.2 (−0.5; 0.2) g/dL for days 1–5, 0.2 (0.0; 0.7) g/dL for days 6–10, 0.7 (0.2; 1.1) g/dL for days 11–15, 0.7 (0.2; 1.8) g/dL for days 16–20, 0.9 (0.3; 1.7) g/dL for days 21–25, 1.5 (0.4; 2.6) g/dL for days 26–30, and 0.6 (0.0; 1.7) g/dL for >31 days. Three patients received multiple administrations of IV iron which resulted in an increase in Hb of >4 g/dL.DiscussionSupplementation of IV iron to increase Hb concentration preoperatively may be most effective if administered at least ten days before surgery.     

A Phase III,randomized, open‐label trial of ferumoxytol compared with iron sucrose for the treatment of iron deficiency anemia in patients with a history of unsatisfactory oral iron therapy

Iron deficiency anemia (IDA) is the most common form of anemia worldwide. Although oral iron is used as first‐line treatment, many patients are unresponsive to or cannot take oral iron. This Phase III, open‐label, non‐inferiority study compared the efficacy and safety of ferumoxytol, a rapid, injectable intravenous (IV) iron product with low immunological reactivity and minimal detectable free iron, with IV iron sucrose in adults with IDA of any cause. Patients (N = 605) were randomized 2:1 to receive ferumoxytol (n = 406, two doses of 510 mg 5 ± 3 days apart) or iron sucrose (n = 199, five doses of 200 mg on five nonconsecutive days over 14 days) and followed for 5 weeks. Ferumoxytol demonstrated noninferiority to iron sucrose at the primary endpoint, the proportion of patients achieving a hemoglobin increase of ≥2 g dL^?1 at any time from Baseline to Week 5 (ferumoxytol, 84.0% [n = 406] vs. iron sucrose, 81.4% [n = 199]), with a noninferiority margin of 15%. Ferumoxytol was superior to iron sucrose (2.7 g dL^?1 vs. 2.4 g dL^?1) in the mean change in hemoglobin from Baseline to Week 5 (the alternative preplanned primary endpoint) with P = 0.0124. Transferrin saturation, quality‐of‐life measures, and safety outcomes were similar between the two treatment groups. Overall, ferumoxytol demonstrated comparable safety and efficacy to iron sucrose, suggesting that ferumoxytol may be a useful treatment option for patients with IDA in whom oral iron was unsatisfactory or could not be used.

Comparative efficacy and safety of intravenous ferric carboxymaltose and iron sucrose for iron deficiency anemia in obstetric and gynecologic patients: A systematic review and meta-analysis

Introduction:Iron deficiency anemia (IDA) is common among obstetric and gynecologic patients. This systematic review aimed to assess the comparative efficacy and safety of commonly used intravenous (IV) iron formulations, ferric carboxymaltose (FCM), and iron sucrose (IS) in the treatment of IDA in obstetric and gynecologic patients.Methods:We systematically searched PubMed, EMBASE, Cochrane CENTRAL, and Google Scholar for eligible randomized controlled trials (RCTs) comparing IV iron replacement using FCM and IS up to October 2019. The primary outcome was to compare the efficacy of FCM and IS, assessed by measuring serum hemoglobin (Hb) and ferritin levels before and after iron replacement. The secondary outcome was to compare the safety of FCM and IS, assessed by the incidence of adverse events during iron replacement. The meta-analysis was performed using RevMan 5.3.Results:We identified 9 RCTs with 910 patients (FCM group, n = 456; IS group, n = 454). Before iron replacement, FCM and IS group patients had similar baseline Hb (mean difference [MD], 0.04 g/dL; 95% confidence interval [CI], −0.07 to 015; I² = 0%; P = 0.48) and ferritin levels (MD, −0.42 ng/mL; 95% CI, −1.61 to 0.78; I² = 45%; P = 0.49). Following iron replacement, patients who received FCM had higher Hb (MD, 0.67; 95% CI, 0.25–1.08; I² = 92%; P = 0.002) and ferritin levels (MD, 24.41; 95% CI, 12.06–36.76; I² = 75%; P = 0.0001) than patients who received IS. FCM group showed a lower incidence of adverse events following iron replacement than IS group (risk ratio, 0.53; 95% CI, 0.35–0.80; I² = 0%; P = 0.003). Serious adverse events were not reported in any group.Conclusion:FCM group showed better efficacy in increasing Hb and ferritin levels and a favorable safety profile with fewer adverse events compared with IS group for IDA treatment among obstetric and gynecologic patients. However, this meta-analysis was limited by the small number of RCTs and high heterogeneity.Trial registration:The review was prospectively registered with the International Prospective Registry of Systematic Reviews (https://www.crd.york.ac.uk/prospero/, registration number CRD42019148905).     

Labile plasma iron,more practical and more sensitive to iron overload in myelodysplastic syndromes

Objectives: In order to gain an insight into labile plasma iron (LPI) in iron metabolism microenvironment in MDS.

Methods: We performed ELISA, quantitative real-time polymerase chain reaction, flow cytometry, MRI T2* assays to test LPI, iron biochemical parameters, and liver iron concentration (LIC) among 22 MDS patients.

Results: LPI has a statistical difference (P?P?=?0.086 by ANOVA). After DFO treatment, serum hepcidin expression increased from 301.26?±?59.78 to 340.33?±?49.78?µg/l (P?=?0.032), while hepcidin/ASF was upregulated gradually from 0.16?±?0.08 to 0.22?±?0.03 (P?=?0.045). APAF-1 expression (P?=?0.047) and erythroid apoptosis rate (P?=?0.009) decreased significantly, respectively. No statistical difference was found in EPO (P?=?0.247) and GDF15 expression (P?=?0.172). LIC dropped from 9.83?±?4.84 to 6.28?±?4.01?mg/g dry weight (P?P?=?0.594). LPI has a closer connection to LIC than ASF (r?=?0.739, P?r?=?0.321, P?=?0.034).

Discussion: LPI seems to be a real-time indicator which reflects body iron loading status instantaneously. Despite the limited knowledge available on LPI speciation in different types and degrees of IO, LPI measurements can be and are in fact used for identifying systemic IO and for initiating/adjusting chelation regimens.     

Intravenous iron sucrose versus oral iron supplementation for the treatment of iron deficiency anemia in patients with inflammatory bowel disease--a randomized, controlled, open-label, multicenter study

OBJECTIVES: Anemia is a frequent complication in patients with inflammatory bowel disease (IBD). The optimal route for iron supplementation to replenish iron stores has not been determined so far. We therefore evaluated the efficacy and safety of intravenous iron sucrose as compared with oral iron sulfate for the treatment of iron deficiency anemia (IDA) in patients with IBD. METHODS: A randomized, prospective, open-label, multicenter study was performed in 46 patients with anemia and transferrin saturation 相似文献   

Iron replacement therapy in inflammatory bowel disease patients with iron deficiency anemia: A systematic review and meta-analysis

Background and aimsIron deficiency anemia (IDA) is a common problem in patients with Inflammatory Bowel Disease (IBD) and has a significant negative impact on quality of life. The aim was to compare the clinical efficacy of intravenous (IV) versus oral (PO) iron replacement in adult IBD with iron deficiency anemia (IDA).MethodsA systematic search for randomized controlled trials comparing the efficacy of IV versus PO iron therapy in the treatment of IDA in adult IBD patients. The primary outcome was the mean change in the hemoglobin at the end of study and secondary outcomes include mean change in ferritin, clinical disease activity index, quality of life score and the adverse reaction rate.ResultsThe search strategy identified 757 articles while only three industry-funded articles met the inclusion criteria for systematic review and meta-analysis. The total sample size was 333 patients with 203 patients receiving IV therapy. IV route was associated with a 6.8 g/L higher mean hemoglobin increment and 110 μg/L higher mean ferritin increment. The IBD activity index and Quality of Life scores were comparable between the two treatment groups. More adverse events were reported in the oral treatment group with the odds for discontinuation being 6.2 (CI 2.2, 17.1).ConclusionsIntravenous iron treatment is better tolerated and more effective than oral iron treatment in improving ferritin. The higher hemoglobin gain with the IV route was small and of uncertain clinical significance. The combined sample size of the included studies was small and further clinical trials are required.

Long-term effects of an oral iron chelator,deferasirox, in hemodialysis patients with iron overload

Abstract

Background/Purpose

Retention of excess iron from transfused blood in organs in patients with renal anemia may lead to various systemic complications. Iron chelating agents such as deferasirox (DFX) decrease such iron overload. This study assessed the efficacy, safety, and tolerability of DFX in hemodialysis (HD) patients with iron overload.

Methods

We retrospectively (February 2008 to June 2012) reviewed data for eight HD patients with end-stage renal disease who were prescribed DFX (15 mg/kg/day) for transfusion-induced iron overload. Baseline and post-treatment levels of hematocrit, ferritin, erythropoietin (EPO), transferrin saturation (TSAT), total and unsaturated iron-binding capacity (TIBC and UIBC, respectively), and blood transfusion volumes were measured. Treatment efficacy was evaluated by observing changes in ferritin and TSAT during the study period; monthly EPO doses and blood transfusions were also recorded. Safety was evaluated in the form of adverse events.

Results

DFX administration caused statistically significant reductions in TSAT (68.2–49.2%; P = 0.036) and ferritin (3133.1–1215.6 ng/ml; P = 0.017). Significant post-treatment increases in UIBC (63.3–196.6 µg/dl; P = 0.018) and TIBC (210.0–422.4 µg/dl; P = 0.012) were also observed. While there were no significant differences in hematocrit values or EPO requirements after treatment, significant reductions in average monthly transfusion volumes (P = 0.026) were recorded. DFX was generally well tolerated; common adverse effects included nausea, vomiting, diarrhea, and abdominal pain.

Conclusion

DFX significantly improved iron metabolism in HD patients with iron overload and had an acceptable frequency of adverse effects.     

A Pilot Evaluation of the Long-term Effect of Combined Therapy With Intravenous Iron Sucrose and Erythropoietin in Elderly Patients With Advanced Chronic Heart Failure and Cardio-Renal Anemia Syndrome: Influence on Neurohormonal Activation and Clinical Outcomes

BackgroundThe prognosis in elderly patients with advanced chronic heart failure (CHF) and cardio-renal anemia syndrome (CRAS) is ominous, and treatment alternatives in this subset of patients are scarce.Methods and ResultsTo assess the long-term influence of combined therapy with intravenous (IV) iron and erythropoietin (rHuEPO) on hemoglobin (Hb), natriuretic peptides (NT-proBNP), and clinical outcomes in elderly patients with advanced CHF and mild-to-moderate renal dysfunction and anemia (CRAS) who are not candidates for other treatment alternatives, 487 consecutive patients were evaluated. Of them, 65 fulfilling criteria for entering the study were divided into 2 groups and treated in an open-label, nonrandomized fashion: intervention group (27, combined anemia therapy) and control group (38, no treatment for anemia). At baseline, mean age was 74 ± 8 years, left ventricular ejection fraction was 34.5 ± 14.1, Hb was 10.9 ± 0.9 g/dL, creatinine was 1.5 ± 0.5 mg/dL, NT-proBNP was 4256 ± 4952 pg/mL, and 100% were in persistent New York Heart Association (NYHA) Class III or IV. At follow-up (15.3 ± 8.6 months), patients in the intervention group had higher levels of hemoglobin (13.5 ± 1.5 vs. 11.3 ± 1.1; P < .0001), lower levels of natural log of NT-proBNP (7.3 ± 0.8 vs. 8.0 ± 1.3, P = .016), better NYHA functional class (2.0 ± 0.6 vs. 3.3 ± 0.5; P < .001), and lower readmission rate (25.9% vs. 76.3%; P < .001). In the multivariate Cox proportional hazards model, combined therapy was associated with a reduction of the combined end point all-cause mortality or cardiovascular hospitalization (HR 95%CI 0.2 [0.1-0.6]; P < .001).ConclusionLong-term combined therapy with IV iron and rHuEPO may increase Hb, reduce NT-proBNP, and improve functional capacity and cardiovascular hospitalization in elderly patients with advanced CHF and CRAS with mild to moderate renal dysfunction.     

Effects of intravenous iron saccharate on improving severe anemia in rheumatoid arthritis patients

Anemia in rheumatoid arthritis (RA) is multifactorial. Iron deficiency, either definite or relative (defect in iron utilization), exists in RA patients with anemia. Intravenous iron therapy is indicated in severe and symptomatic cases or those with conditions precluding use of oral iron, but its safety and long-term efficacy have not been well-established. Forty severe anemic (hemoglobin < 9 g/dL) RA patients with or without demonstrable bone marrow iron stain were enrolled in this study. Fractionated administration of intravenous iron saccharate was undertaken and the median follow-up time was 1 year. All patients exhibited significant elevations of hemoglobin 3 months after treatment, which were more pronounced in the nonstainable iron marrow subjects {median (interquartile range): 3.8 (2.9–4.8) g/dL versus 2.9 (2.0–3.0) g/dL, p < 0.01}. Thereafter, hemoglobin remained at a plateau level that lasted during the observation period. Throughout the whole course, none of the cases exhibited side effects or flare up of disease activities. The use of intravenous iron saccharate, preferably administrated in a fractionated way, is effective in the correction of severe anemia in RA patients, especially those with nonstainable iron marrow.     

Treatment of anaemia in inflammatory bowel disease with iron sucrose

Background: Inflammatory bowel disease (IBD)‐associated anaemia usually responds to intravenous iron. If not, additive treatment with erythropoietin has been proposed. The objective of the present retrospective study was to evaluate the effectiveness of treatment with iron sucrose alone. Methods: Sixty‐one patients with IBD and anaemia (average haemoglobin 97?g/L) were treated with iron sucrose (iron dose 1.4?±?0.5?g). The indications for iron sucrose were poor response and/or intolerance to oral iron. Treatment response was defined as an increase in haemoglobin of ≥20?g/L or to normal haemoglobin levels (≥120?g/L). Two independent investigators retrospectively assessed laboratory variables, clinical findings, and concomitant medication. Results: Two patients were transferred to other hospitals after treatment and therefore could not be evaluated. Fifty‐four of the remaining 59 patients (91%) responded within 12 weeks. Sixty percent of the patients had responded within 8 weeks. Five patients had no or only a partial response to iron sucrose of which three had prolonged gastrointestinal blood losses. Eight patients with normal or elevated levels of ferritin could be considered to have anaemia of chronic disease, and all of them responded to iron sucrose. During a follow‐up period of 117?±?85 (4–291) (mean?±?s (standard deviation) (range)) weeks 19 patients (32%) needed at least one second course of iron sucrose because of recurrent disease. Conclusions: Anaemia associated with IBD can be successfully treated with intravenously administered iron sucrose, provided that bowel inflammation is treated adequately and enough iron is given. Treatment with iron sucrose is safe. Follow‐up of haemoglobin and iron parameters to avoid further iron deficiency anaemia is recommended.     

Sequential treatment of anemia in ulcerative colitis with intravenous iron and erythropoietin.

BACKGROUND: Intravenous iron and erythropoietin have been shown to be effective in Crohn's disease-associated anemia. The aim of this study was to test the sequential treatment of anemia in ulcerative colitis with intravenous iron in the first phase and erythropoietin in the second. PATIENTS AND METHODS: Twenty patients with ulcerative colitis-associated anemia (hemoglobin < or = 10.5 g/dl) entered this open-label trial. In the first phase all patients received intravenous iron saccharate for 8 weeks. A response was defined as an increase in hemoglobin > or = 2.0 g/dl; a final hemoglobin >10.5 g/dl was regarded as full response, < or = 10.5 g/dl as partial response. A hemoglobin increase < 2.0 g/dl was regarded as nonresponse. In the second phase (n = 4) erythropoietin was initiated in patients without response. Patients with partial response were continued on iron saccharate for another 8 weeks. RESULTS: During the first phase the hemoglobin increased from 8.3 to 11.9 g/dl (mean hemoglobin difference 3.6+/-2.3 g/dl, p < 0.001). Fifteen patients (75%) showed a full response (mean hemoglobin difference 4.5+/-1.5 g/dl), 1 (5%) a partial response (hemoglobin difference 2.1 g/dl) and 4 no response (mean hemoglobin difference 0.4+/-1.8 g/dl) with a need for blood transfusions in a single patient. In the second study phase erythropoietin was highly effective in previous nonresponders (mean hemoglobin difference 3.3+/-1.9 g/dl). The single patient with partial response had a minor hemoglobin increase (hemoglobin difference 1.0 g/dl). CONCLUSION: Most patients with ulcerative colitis-associated anemia improve on intravenous iron alone. Erythropoietin is effective in those who do not respond.
