RESUMEN

BACKGROUND: Evidence for the management of moderate-to-severe postpartum anemia is limited. A randomized trial is needed; recruitment may be challenging. STUDY DESIGN AND METHODS: Randomized pilot trial with feasibility surveys. INCLUSION: hemoglobin 65-79 g/L, ≤7 days of birth, hemodynamically stable. EXCLUSION: ongoing heavy bleeding; already received, or contraindication to intravenous (IV)-iron or red blood cell transfusion (RBC-T). Intervention/control: IV-iron; RBC-T; or IV-iron and RBC-T. PRIMARY OUTCOME: number of recruits; proportion of those approached; proportion considered potentially eligible. SECONDARY OUTCOMES: fatigue, depression, baby-feeding, and hemoglobin at 1, 6 and 12 weeks; ferritin at 6 and 12 weeks. Surveys explored attitudes to trial participation. RESULTS: Over 16 weeks and three sites, 26/34 (76%) women approached consented to trial participation, including eight (31%) Maori women. Of those potentially eligible, 26/167 (15.6%) consented to participate. Key participation enablers were altruism and study relevance. For clinicians and stakeholders the availability of research assistance was the key barrier/enabler. Between-group rates of fatigue and depression were similar. Although underpowered to address secondary outcomes, IV-iron and RBC-T compared with RBC-T were associated with higher hemoglobin concentrations at 6 (mean difference [MD] 11.7 g/L, 95% confidence interval [CI] 2.7-20.7) and 12 (MD 12.8 g/L, 95% CI 1.5-24.2) weeks, and higher ferritin concentrations at 6 weeks (MD 136.8 mcg/L, 95% CI 76.6-196.9). DISCUSSION: Willingness to participate supports feasibility for a future trial assessing the effectiveness of IV-iron and RBC-T for postpartum anemia. Dedicated research assistance will be critical to the success of an appropriately powered trial including women-centered outcomes.

RESUMEN

BACKGROUND: Intravenous iron (IV-iron) is used as an alternative to, or alongside, red blood cell transfusion (RBC-T) to treat more severe postpartum anemia (PPA), although optimal treatment options remain unclear. No previous systematic reviews have examined IV-iron and RBC-T, including patient-reported outcomes and hematological responses. METHODS: A systematic review and meta-analysis of randomized trials comparing IV-iron and RBC-T with each other, oral iron, no treatment, and placebo for the treatment of PPA. Key inclusion criteria were PPA (hemoglobin < 12 g/dL) and IV-iron or RBC-T as interventions. Key exclusion criteria were antenatal IV-iron or RBC-T. Fatigue was the primary outcome. Secondary outcomes included hemoglobin and ferritin concentrations, and adverse events. From 27th August 2020 to 26th September 2022, databases, registries, and hand searches identified studies. A fixed-effect meta-analysis was undertaken using RevMan (5.4) software. The quality of the studies and the evidence was assessed using the Cochrane Risk of Bias table, and Grading of Recommendations, Assessment, Development, and Evaluation. This review is registered with the Prospective Register of Systematic Reviews (CRD42020201115). RESULTS: Twenty studies and 4196 participants were included: 1834 assigned IV-iron, 1771 assigned oral iron, 330 assigned RBC-T, and 261 assigned non-intervention. Six studies reported the primary outcome of fatigue (1251 participants). Only studies of IV-iron vs. oral iron (15 studies) were available for meta-analysis. Of these, three reported on fatigue using different scales; two were available for meta-analysis. There was a significant reduction in fatigue with IV-iron compared to oral iron (standardized mean difference - 0.40, 95% confidence interval (CI) - 0.62, - 0.18, I2 = 0%). The direction of effect also favored IV-iron for hemoglobin (mean difference (MD) 0.54 g/dL, 95% confidence interval (CI) 0.47, 0.61, I2 = 91%), ferritin, (MD 58.07 mcg/L, 95% CI 55.74, 60.41, I2 = 99%), and total adverse events (risk-ratio 0.63, 95% CI 0.52, 0.77, I2 = 84%). The overall quality of the evidence was low-moderate. DISCUSSION: For all outcomes, the evidence for RBC-T, compared to IV-iron, non-intervention, or dose effects of RBC-T is very limited. Further research is needed to determine whether RBC-T or IV-iron for the treatment of PPA is superior for fatigue and hematological outcomes.

RESUMEN

BACKGROUND AND OBJECTIVES: Hematinic deficiency irrespective of anemia is not uncommon in patients with heart failure. We studied the prevalence, distribution, and etiology of anemia in patients with heart failure with reduced ejection fraction (HFrEF) and compared it with non-anemic patients. METHODS: Congestive heart failure (CHF) was diagnosed by modified Framingham criteria and ejection fraction (EF) <40%. Iron deficiency (ID) anemia was defined as serum ferritin level <100 ng/ml (absolute) or 100-300 ng/ml with transferrin saturation <20% (functional). Vitamin B12 and folate deficiency were defined as <200pg/ml and <4ng/ml respectively. RESULT: 688 patients with HFrEF were studied with an overall mean age of 57.2±13.8 years, and males outnumbering females (62.3% vs. 37.7%). Coronary artery disease (44.2%), dilated cardiomyopathy (46.8%), and valvular heart disease (6.7%) were major causes of CHF.Anemia was found in 63.9% of patients. Vit B12 deficiency, and folate deficiency were found in 107 (15.55%), and 54 (7.85%) subjects, respectively. Absolute ID was detected in 186 (42.27%) patients with anemia and 84 (33.87%) patients without anemia, while functional ID was present in 80 (18.18%) patients with anemia and 29 (11.69%) patients without anemia. Vitamin B12 deficiency was noted in 70 (15.9%) patients with anemia and 37 (14.9%) patients without anemia, while folate deficiency was noted in 31 (7.04%) patients with anemia and 23 (9.2%) patients without anemia. Hematinic deficiency among the study population was distributed equally among patients irrespective of EF, NYHA class, socioeconomic class diet pattern. CONCLUSION: The study shows that hematinic deficiency was seen even in non-anemic patients irrespective of diet pattern. Supplementation could be a strong strategy to improve outcomes in these patients of heart failure irrespective of anemia and should be evaluated in prospective studies.

RESUMEN

BACKGROUND: Iron supplementation and erythropoiesis-stimulating agent (ESA) administration represent the hallmark therapies in preoperative anemia treatment, as reflected in a set of evidence-based treatment recommendations made during the 2018 International Consensus Conference on Patient Blood Management. However, little is known about the safety of these therapies. This systematic review investigated the occurrence of adverse events (AEs) during or after treatment with iron and/or ESAs. METHODS: Five databases (The Cochrane Library, MEDLINE, Embase, Transfusion Evidence Library, Web of Science) and two trial registries (ClinicalTrials.gov, WHO ICTRP) were searched until 23 May 2022. Randomized controlled trials (RCTs), cohort, and case-control studies investigating any AE during or after iron and/or ESA administration in adult elective surgery patients with preoperative anemia were eligible for inclusion and judged using the Cochrane Risk of Bias tools. The GRADE approach was used to assess the overall certainty of evidence. RESULTS: Data from 26 RCTs and 16 cohort studies involving a total of 6062 patients were extracted, on 6 treatment comparisons: (1) intravenous (IV) versus oral iron, (2) IV iron versus usual care/no iron, (3) IV ferric carboxymaltose versus IV iron sucrose, (4) ESA+iron versus control (placebo and/or iron, no treatment), (5) ESA+IV iron versus ESA+oral iron, and (6) ESA+IV iron versus ESA+IV iron (different ESA dosing regimens). Most AE data concerned mortality/survival (n=24 studies), thromboembolic (n=22), infectious (n=20), cardiovascular (n=19) and gastrointestinal (n=14) AEs. Very low certainty evidence was assigned to all but one outcome category. This uncertainty results from both the low quantity and quality of AE data due to the high risk of bias caused by limitations in the study design, data collection, and reporting. CONCLUSIONS: It remains unclear if ESA and/or iron therapy is associated with AEs in preoperatively anemic elective surgery patients. Future trial investigators should pay more attention to the systematic collection, measurement, documentation, and reporting of AE data.

RESUMEN

Patient Blood Management (PBM) is an evidence-based, multidisciplinary, patient-centred approach to optimizing the care of patients who might need a blood transfusion. This systematic review aimed to collect the best available evidence on the effectiveness of preoperative iron supplementation with or without erythropoiesis-stimulating agents (ESAs) on red blood cell (RBC) utilization in all-cause anaemic patients scheduled for elective surgery. Five databases and two trial registries were screened. Primary outcomes were the number of patients and the number of RBC units transfused. Effect estimates were synthesized by conducting meta-analyses. GRADE (Grades of Recommendation, Assessment, Development and Evaluation) was used to assess the certainty of evidence. We identified 29 randomized controlled trials (RCTs) and 2 non-RCTs comparing the effectiveness of preoperative iron monotherapy, or iron + ESAs, to control (no treatment, usual care, placebo). We found that: (1) IV and/or oral iron monotherapy may not result in a reduced number of units transfused and IV iron may not reduce the number of patients transfused (low-certainty evidence); (2) uncertainty exists whether the administration route of iron therapy (IV vs oral) differentially affects RBC utilization (very low-certainty evidence); (3) IV ferric carboxymaltose monotherapy may not result in a different number of patients transfused compared to IV iron sucrose monotherapy (low-certainty evidence); (4) oral iron + ESAs probably results in a reduced number of patients transfused and number of units transfused (moderate-certainty evidence); (5) IV iron + ESAs may result in a reduced number of patients transfused (low-certainty evidence); (6) oral and/or IV iron + ESAs probably results in a reduced number of RBC units transfused in transfused patients (moderate-certainty evidence); (7) uncertainty exists about the effect of oral and/or IV iron + ESAs on the number of patients requiring transfusion of multiple units (very low-certainty evidence). Effect estimates of different haematological parameters and length of stay were synthesized as secondary outcomes. In conclusion, in patients with anaemia of any cause scheduled for elective surgery, the preoperative administration of iron monotherapy may not result in a reduced number of patients or units transfused (low-certainty evidence). Iron supplementation in addition to ESAs probably results in a reduced RBC utilization (moderate-certainty evidence).

RESUMEN

BACKGROUND: We explored the association of anemia severity in patients with chronic kidney disease (CKD) and anemia treatment with work productivity in China. METHODS: Cross-sectional survey data from Chinese physicians and their CKD patients were collected in 2015. Physicians recorded demographics, disease characteristics, and treatment. Patients completed the Work Productivity and Activity Impairment questionnaire. Data were stratified by dialysis-dependence, hemoglobin (Hb) level, and anemia treatment. RESULTS: Based on data from 1,052 patients (704 non-dialysis-dependent [NDD] and 348 dialysis-dependent [DD] patients), prescribed anemia treatment differed significantly across Hb levels (P < 0.001). In NDD patients, anemia treatment also differed significantly by on-treatment Hb level (P < 0.001). In treated NDD patients with Hb < 10 g/ dL, Hb 10 to 12 g/dL, and Hb > 12 g/dL, 31%, 59%, and 38% of patients, respectively, were prescribed oral iron, and 34%, 19%, and 0% of patients, respectively, were prescribed oral iron with erythropoiesis-stimulating agents (ESA). NDD patients were less likely to be prescribed any anemia treatment, and ESA specifically, than DD patients. When treated, 67% and 45% of NDD and DD patients, respectively, had Hb ≥ 10 g/dL (P < 0.001). Overall work and activity impairment differed significantly across Hb levels in NDD and DD patients, with the least impairment observed at the highest Hb level. CONCLUSION: Approximately 40% of NDD patients and 60% of DD patients receiving anemia treatment had Hb < 10 g/dL. Compared with mild anemia patients, severe anemia patients were more likely to be treated for anemia and have impaired work productivity. Chinese CKD patients could benefit from improved anemia treatment.

RESUMEN

BACKGROUND AND OBJECTIVES: Large, randomized, controlled trials targeting higher hemoglobin level with erythropoiesis-stimulating agents for Western patients with CKD showed harm. However, the effect of anemia correction using erythropoiesis-stimulating agents may differ between CKD subpopulations. The Prevention of ESKD by Darbepoetin Alfa in CKD Patients with Non-diabetic Kidney Disease study, a multicenter, randomized, open-label, parallel-group study, aimed to examine the effect of targeting hemoglobin levels of 11-13 g/dl using darbepoetin alfa with reference to a low-hemoglobin target of 9-11 g/dl on kidney outcome in patients with advanced CKD without diabetes in Japan. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We enrolled 491 patients with CKD without diabetes, and an eGFR of 8-20 ml/min per 1.73 m2. Of these 491 patients, 239 and 240 were ultimately assigned to the high- and low-hemoglobin groups, respectively (12 patients were excluded). The primary outcome was a kidney composite end point (starting maintenance dialysis, kidney transplantation, eGFR≤6 ml/min per 1.73 m2, and 50% reduction in eGFR). RESULTS: Mean hemoglobin levels were 11.2±1.1 and 10.0±0.9 g/dl in the high- and low-hemoglobin groups, respectively, during the mean study period of 73.5±29.7 weeks. The kidney composite end point occurred in 105 (44%) and 116 (48%) patients in the high- and low-hemoglobin groups, respectively (log-rank test; P=0.32). The adjusted Cox proportional hazards model showed that the hazard ratio for the high- versus low-hemoglobin group was 0.78 (95% confidence interval, 0.60 to 1.03; P=0.08). Cardiovascular events occurred in 19 (8%) and 16 (7%) patients in each group, respectively, with no significant between-group difference (log-rank test; P=0.66). CONCLUSIONS: Targeting a higher hemoglobin level (11-13 g/dl) with darbepoetin alfa did not improve kidney outcome compared with targeting a lower hemoglobin level (9-11 g/dl) in patients with advanced CKD without diabetes. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER: Prevention of ESKD by Darbepoetin Alfa in CKD Patients with Non-diabetic Kidney Disease (PREDICT), NCT01581073.

RESUMEN

Aims: The overall cost and health-related quality of life (HRQoL) associated with current treatments for chronic kidney disease (CKD)-related anemia are not well characterized. A systematic literature review (SLR) was conducted on the costs and HRQoL associated with current treatments for CKD-related anemia among dialysis-dependent (DD) patients. Materials and methods: The authors searched the Cochrane Library, MEDLINE, EMBASE, NHS EED, and NHS HTA for English-language publications. Original studies published between January 1, 2000 and March 17, 2017 meeting the following criteria were included: adult population; study focus was CKD-related anemia; included results on patients receiving iron supplementation, red blood cell transfusion, or erythropoiesis stimulating agents (ESAs); reported results on HRQoL and/or costs. Studies which included patients with DD-CKD, did not directly compare different treatments, and had designs relevant to the objective were retained. HRQoL and cost outcomes, including healthcare resource utilization (HRU), were extracted and summarized in a narrative synthesis. Results: A total of 1,625 publications were retrieved, 15 of which met all inclusion criteria. All identified studies included ESAs as a treatment of interest. Two randomized controlled trials reported that ESA treatment improves HRQoL relative to placebo. Across eight studies comparing HRQoL of patients achieving high vs low hemoglobin (Hb) targets, aiming for higher Hb targets with ESAs generally led to modest HRQoL improvements. Two studies reported that ESA-treated patients had lower costs and HRU compared to untreated patients. One study found that aiming for higher vs lower Hb targets led to reduced HRU, while two other reported that this led to a reduction in cost-effectiveness. Limitations: Heterogeneity of study designs and outcomes; a meta-analysis could not be performed. Conclusions: ESA-treated patients undergoing dialysis incurred lower costs, lower HRU, and had better HRQoL relative to ESA-untreated patients. However, treatment to higher Hb targets led to modest HRQoL improvements compared to lower Hb targets.

RESUMEN

BACKGROUND AND OBJECTIVES: Erythropoiesis-stimulating agents correct anemia of CKD but may increase cardiovascular risk. We compared cardiovascular outcomes and all-cause mortality associated with monthly methoxy polyethylene glycol-epoetin beta with those of the shorter-acting agents epoetin alfa/beta and darbepoetin alfa in patients with anemia of CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a multicenter, open-label, noninferiority trial in which patients were randomized to receive methoxy polyethylene glycol-epoetin beta or reference erythropoiesis-stimulating agents, stratified by maintenance or correction treatment status and C-reactive protein level. The trial had a prespecified noninferiority margin of 1.20 for the hazard ratio (HR) for the primary end point (a composite of all-cause mortality, nonfatal myocardial infarction or stroke, adjudicated by an independent blinded committee). This trial is registered with ClinicalTrials.gov, number NCT00773513. RESULTS: In total, 2818 patients underwent randomization, received methoxy polyethylene glycol-epoetin beta or a reference agent, and were followed for a median of 3.4 years (maximum, 8.4 years). In the modified intention-to-treat analysis, a primary end point event occurred in 640 (45.4%) patients in the methoxy polyethylene glycol-epoetin beta arm, and 644 (45.7%) in the reference arm (HR 1.03; 95% confidence interval [95% CI], 0.93 to 1.15, P=0.004 for noninferiority). All-cause mortality was not different between treatment groups (HR 1.06; 95% CI, 0.94 to 1.19). Results in patient subgroups on dialysis or treated in the correction or maintenance settings were comparable to the primary analysis. CONCLUSIONS: In patients with anemia of CKD, once-monthly methoxy polyethylene glycol-epoetin beta was noninferior to conventional, shorter-acting erythropoiesis-stimulating agents with respect to rates of major adverse cardiovascular events or all-cause mortality.

RESUMEN

BACKGROUND AND OBJECTIVES: The study was conducted to identify a conversion factor for switching from previous erythropoiesis-stimulating agents (ESAs) to continuous erythropoietin receptor activator-methoxy polyethylene glycol-epoetin beta (C.E.R.A.) and to document the efficacy and long-term safety of C.E.R.A. in pediatric patients with anemia of CKD undergoing hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In this open-label, multicenter study, patients aged 6-17 years, with stable chronic anemia of CKD, undergoing hemodialysis received C.E.R.A. every 4 weeks, at a starting dose determined by previous weekly epoetin alfa/beta or darbepoetin dosing. After a 16-week dose-titration and a 4-week evaluation period, patients with stable hemoglobin could enter a 1-year optional safety extension. RESULTS: A total of 64 patients were enrolled. A conversion factor (4 µg every 4 weeks for each weekly dose of 125 IU epoetin alfa/beta or 0.55 µg darbepoetin) was identified that allowed patients to maintain hemoglobin within target levels on switching to C.E.R.A. from another ESA. Using this conversion factor, the adjusted mean change in hemoglobin from baseline to evaluation was -0.09 g/dl (95% confidence interval, -0.45 to 0.26); 81% of patients maintained hemoglobin within 10.0-12.0 g/dl and 75% maintained hemoglobin within 1.0 g/dl of baseline. Results were consistent across age groups (6-11 and 12-17 years) and previous ESA. Thirty-seven patients entered the safety extension period and 17 completed 73 weeks of treatment. Most withdrawals were for kidney transplantation. A total of 70% of patients had hemoglobin within 10.0-12.0 g/dl at last observation, and 62% were within ±1.0 g/dl of baseline. Safety was similar to studies in adult patients, with no new signal detected. CONCLUSIONS: Using a defined conversion factor, 4-weekly C.E.R.A. was efficacious in maintaining hemoglobin levels in pediatric patients with stable anemia of CKD undergoing hemodialysis, switching from maintenance treatment with epoetin alfa/beta or darbepoetin. Safety was consistent with the known C.E.R.A. safety profile in adults.

RESUMEN

OBJECTIVE: Anemia in patients presenting for elective surgery is associated with increased morbidity, allogeneic blood transfusion, and delay of surgery. Extract of sorghum bicolor has been shown to have hemopoietic, immune-stimulating, and antioxidant effects in rats and in patients with HIV. The aim of this study was to determine the effect of the extract in patients with preoperative anemia booked for myomectomy. METHODS: Consenting patients (N = 66) were randomly assigned to two groups. The test group (n = 34) was given folic acid 5 mg/d, 200 mg iron tablet three times daily, and 500 mg/d of the extract. The control group (n = 32) was given the same doses of folic acid and iron for a period of 3 wk. Blood samples were taken at baseline and weekly for full blood cell count and liver and kidney function tests. Participants were screened for tuberculosis, HIV, hepatitis, and sickle cell anemia. RESULTS: Increases in red blood cell count, hematocrit, and hemoglobin concentration in participants in the test group were highly significant (P < 0.0002, P < 0.0001, and P < 0.0001, respectively). Participants in the control group had a significant increase in the hemoglobin concentration (P > 0.04). The changes in liver enzymes, urea, and creatinine for participants in the test group were within the normal ranges. CONCLUSION: The addition of the extract of sorghum bicolor to routine hematinics is superior to the use of routine hematinics alone. Although the difference is not statistically significant, the extract will correct preoperative anemia in an additional 15% of the patients.

RESUMEN

INTRODUCTION: Chronic heart failure (HF) is frequently accompanied by one or more comorbidities. The presence of comorbidities in chronic HF is strongly correlated to HF severity and impaired outcome. AREAS COVERED: This review will address several comorbidities with high prevalence and/or high impact in patients with chronic HF, including diabetes, anemia, hematinic deficiencies, and hyperkalemia. The background and subsequent pharmacotherapeutic options of these comorbidities will be discussed. For this review, a MEDLINE search was performed. EXPERT OPINION: Heart failure is increasingly considered a multimorbid syndrome, including metabolic derangements and chronic inflammation. Persistent metabolic derangements and low-grade inflammation might lead to progression of HF and the development of comorbidities. Although several comorbidity-specific drugs became available in the past decade, most of these therapies are studied in relatively small cohorts using surrogate end-points. Therefore, larger studies are needed to address whether treating these comorbidities will improve patient outcome in chronic HF.

Iron is one among the major metals present in the earth's crust and is essential for sound sustenance of human body. Its deficiency leads to various health ailments. Contemporary medicine advises iron supplements in iron deficiency anemia. Ayurvedic classics also quote significant information about administration of iron. Lauha Kalpas are the unique compound herbo-mineral formulations where iron (Lauha) is used as a major ingredient. Relevant literature (Bhaishajya Ratnavali, Charaka Samhita, Rasendra Sara Samgraha etc.) reviewed to gather information about Lauha Kalpas. Critical analysis of these Lauha Kalpas reveals that ancient seers administered iron in a better acceptable form. Unlike popular understanding these are not only Khalviya preparations; but Churna (powders), Avaleha (confectionaries), Rasakriya (solidified decoctions), and Putapaka (incinerated) form of preparations are also found. Apart from solid dosage forms, semisolid dosage forms mentioned in classics are very much useful. Unfortunately most of the formulations are not found in the market. Hence Pharmaceutical firms may bring these unique dosage forms in to the market to supply the healthcare needs of the community. It is interesting that iron preparations are used in Ayurveda in different medical conditions apart from anemia (Pandu). This leaves a scope for further researches on different dosage forms of iron and their indications.

RESUMEN

Anemia and malnutrition are common complications of end-stage renal disease. They increase the morbidity and mortality of end-stage renal disease patients and affect their quality of life. However, the mechanisms of anemia and malnutrition are already known, and their therapeutic guidelines are being established. Appropriate iron supplementation and the development of erythropoiesis-stimulating agents have made anemia easier to manage than in the past. In addition, adequate protein and calorie intake have allowed end-stage renal disease patients to maintain a neutral or positive nitrogen balance. These therapeutic approaches have decreased the morbidity and mortality of these end-stage renal disease patients. This review is a summary of the treatment of anemia and nutrition in end-stage renal disease, based on the Kidney Disease Outcomes Quality Initiative (KDOQI) guideline on anemia and other anemia guidelines, and also on the KDOQI guideline on nutrition and European Best Practice Guideline (EBPG) on nutrition.

RESUMEN

PURPOSE: This study was undertaken to examine whether differences exist in the hemoglobin variability according to the types of erythropoiesis stimulating agent (ESA) in hemodialysis (HD) patients. METHODS: Clinical data were retrospectively analyzed from 72 patients on maintenance hemodialysis who were using darbepoetin alfa (n=27), epoetin beta (n=27), and epoetin alpha (n=18). As parameters of hemoglobin variability, hemoglobin cycling, the variance of hemoglobin and the SD/mean of hemoglobin were analyzed. Hemoglobin cycling was defined as the presence of cycles with an amplitude >1.5 g/dL and lasting more than 2 months. RESULTS: Hemoglobin cycling was present in 53 (73.6%) out of 72 HD patients. Hemoglobin cycling in patients receiving darbepoetin alfa had greater frequency (1.63+/-0.93 vs. 1.00+/-0.88 times/year, p<0.05), amplitude (2.88+/-1.48 vs. 1.88+/-1.60 g/dL, p<0.05), and velocity (1.21+/-0.74 vs. 0.73+/-0.66 g/dL/month, p<0.05) than that in patients receiving epoetin beta. The variance of hemoglobin in patients receiving epoetin beta (0.79+/-0.53 g/dL) was smaller than that in patients receiving darbepoetin alfa (1.29+/-0.70 g/dL, p<0.05) and epoetin alfa (1.08+/-0.52 g/dL, p<0.05). Also, the ratio of SD/mean of hemoglobin in patients receiving epoetin beta (8.20+/-2.59%) was lower than that in patients receiving darbepoetin alfa (10.81+/-2.10%, p<0.05) and epoetin alfa (10.30+/-2.10%, p<0.05). CONCLUSION: Hemoglobin variability is differential according to various ESAs, and it may be less with epoetin beta compared with darbepoetin alpha and epoetin alpha.

RESUMEN

We investigated the relation between maternal anaemia and neonatal iron status in 97 mothers and their babies. Haemoglobin [Hb], serum iron, total iron binding capacity and serum ferritin were determined. Mothers were divided into 3 groups: iron-deficient anaemic [22.7%], non-anaemic iron-deficient [27.8%] and non-anaemic non-iron-deficient [49.5%]. There was no significant difference in the mean ages of the 3 groups but there were significant differences in relation to parity, Hb and serum ferritin levels. There was no significant difference in the mean value of serum iron or total iron binding capacity among the neonates of the 3 groups. Babies of iron-deficient anaemic mothers had significantly lower levels of serum ferritin [115.3 ng/mL] than nonanaemic, non-iron-deficient mothers [204.8 ng/mL] but not compared with the non-anaemic iron-deficient group. Maternal iron deficiency may affect iron status in their babies and predispose them to iron deficiency
