Abstract
(1) Background: Postpartum anemia is a common maternal complication and is recognized as a cause of impaired quality of life, reduced cognitive abilities, and fatigue. Efficient iron supplementation for the treatment of postpartum anemia is an essential component of high-quality maternal care. The optimal mode of iron supplementation has not been determined yet, whether oral or intravenous. The objective of this study was to compare postpartum anemia treatment with intravenous ferric carboxymaltose, intravenous ferric derisomaltose, and oral ferrous sulfate. (2) Methods: A single-center, open-label, randomized controlled trial. Women with hemoglobin < 100 g/L within 48 h postpartum were randomly allocated to receive intravenous ferric carboxymaltose, intravenous ferric derisomaltose, or oral ferrous sulfate. Intravenous iron was given in one or two doses, while ferrous sulfate was given as two 80 mg tablets once daily. The primary outcome was maternal fatigue measured by the Multidimensional Fatigue Inventory (MFI) six weeks postpartum. Hemoglobin, ferritin, and transferrin saturation levels were analyzed as secondary outcomes. A Kruskal-Wallis test was used for group comparison (p < 0.05 significant). (3) Results: Three hundred women were included. The MFI score at six weeks postpartum did not differ between groups (median 38 (inter-quartile range (IQR) 29-47) in the ferric carboxymaltose group, median 34 (IQR 26-42) in the ferric derisomaltose group, and median 36 (IQR 25-47) in the ferrous sulfate group; p = 0.26). Participants receiving oral iron had lower levels of hemoglobin (135 (131-139) vs. 134 (129-139) vs. 131 (125-137) g/L; p = 0.008), ferritin (273 (198-377) vs. 187 (155-246) vs. 24 (17-37) µg/L; p < 0.001) and transferrin saturation (34 (28-38) vs. 30 (23-37) vs. 24 (17-37) %; p < 0.001) than those receiving ferric carboxymaltose or ferric derisomaltose. (4) Conclusions: Intravenous ferric carboxymaltose, intravenous ferric derisomaltose, and oral ferrous sulfate had similar impacts on maternal fatigue at six weeks postpartum despite improved laboratory parameters in the intravenous groups.

Systematic reviews. 2024;13(1):9
Abstract
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, I(2) = 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, I(2) = 91%), ferritin, (MD 58.07 mcg/L, 95% CI 55.74, 60.41, I(2) = 99%), and total adverse events (risk-ratio 0.63, 95% CI 0.52, 0.77, I(2) = 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.

Clinical outcome post treatment of anemia in pregnancy with intravenous versus oral iron therapy: a systematic review and meta-analysis
Pandey, A. K., Gautam, D., Tolani, H., Neogi, S. B.
Scientific reports. 2024;14(1):179
Abstract
Oral iron therapy is often the most common way of treating anaemia; however intravenous iron is considered effective due to rapid iron replenishment. We have dearth of evidence on clinical outcomes post treatment of anaemia. We have searched studies published in English in PubMed, Cochrane, Scopus, ProQuest, and Google Scholar. Our study analysed the clinical outcomes amongst neonates and mother and the adverse events post treatment and assessed the mean change in maternal haemoglobin concentration in both the groups. Forest plots for the clinical outcomes are presented. From a total of 370 studies, 34 Randomized and quasi experimental studies comparing clinical outcomes post-treatment of anaemia in pregnancy were included for quantitative evidence synthesis. Pooled results of maternal clinical outcomes using random effect model [OR: 0.79 (95% CI 0.66; 0.95); 10 outcomes; 17 studies] showed statistically significant difference among both the groups [Moderate quality evidence]; however no significant difference [OR: 0.99 (95% CI 0.86; 1.14); 7 outcomes; 8 studies] have been observed for neonatal complications [Low quality evidence]. The study found that pregnant women receiving IV iron were significantly less likely to experience adverse events as compared with those receiving oral iron [OR 0.39; (95% CI 0.26-0.60)]; 34 studies; 13,909 women; [Low quality evidence]. Findings from meta-regression analysis showed that IV iron is more likely to reduce maternal complications by 21% compared to oral iron. Increase in odds of adverse maternal outcomes was observed due to increase in gestational age and publication year but no effect for the type of drug used. IV iron increases Hb more and at a higher pace than oral iron. Intravenous iron is more likely to avert adverse maternal outcomes and adverse reactions. However, there is no conclusive evidence on its effectiveness on individual maternal outcome or neonatal outcome/s. Protocol registered with PROSPERO CRD42022368346).

Abstract
OBJECTIVES This study aimed to explore whether the type of iron preparation used to treat postpartum anaemia affects the incidence of postpartum depression and whether the risk of postpartum depression is higher in postpartum patients with anaemia who were adequately treated compared to the general postpartum population. STUDY DESIGN Single-center, open-label, randomized trial. Women were allocated to receive intravenous ferric carboxymaltose, intravenous ferric derisomaltose or oral ferrous sulphate. Intravenous iron was given in one or two doses, while ferrous sulphate as two 80 mg tablets once daily. Primary outcome was postpartum depression measured by Edinburgh Postnatal Depression Scale (EPDS) six weeks postpartum. Haematological parameters were analyzed as secondary outcomes. Kruskal-Wallis test was used for group comparison (p < 0.05 significant). The chi-square test was applied to compare categorical variables as well as the group of all subjects treated for anaemia in the study with the historical data for the Slovenian postpartum population. RESULTS Three-hundred women with postpartum anemia (hemoglobin < 100 g/L within 48-hours postpartum) were included between September 2020 and March 2022 in tertiary perinatal center. Most characteristics were similar across groups. EPDS score at six weeks postpartum did not differ between groups. The treatment modality of postpartum anaemia did not have a statistically significant effect on the EPDS score six weeks after treatment (p = 0.10), nor did it have a statistically significant effect on the difference in EPDS scores before and after treatment (p = 0.68). The proportions of participants who scored 10 or more points on the EPDS scores at six weeks postpartum were not statistically different between the groups (p = 0.79). The proportion of participants with an EPDS score of 10 or more at six weeks postpartum in the total study population did not differ significantly from previously reported proportion of postpartum women with EPDS score of 10 or more in the general population (12 % vs. 21 %; p < 0.001). CONCLUSIONS Maternal depression at 6 weeks postpartum did not differ in women treated for postpartum anemia with intravenous ferric carboxymaltose, intravenous ferric derisomaltose or oral ferrous sulphate. Participants with postpartum anaemia who are adequately treated with either oral or intravenous iron preparations are not at a higher risk of postpartum depression than the general population at six weeks postpartum.

Transfusion. 2023
Abstract
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%) Māori 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.

Abstract
BACKGROUND To our knowledge, there is no prior randomized trial on the efficacy of Mojeaga remedy (a special blend of Alchornea cordifolia, Pennisetum glaucum and Sorghum bicolor extracts) when co-administered with standard-of-care for correction of anemia in obstetrics practice. This study determined the efficacy, safety and tolerability of Mojeaga as adjunct to conventional oral iron therapy for correction of anemia in obstetric population. METHODS A pilot open-label randomized clinical trial. Participants with confirmed diagnosis of anemia in three tertiary hospitals in Nigeria were studied. Eligible participants were randomized 1:1 to either Mojeaga syrups 50 mls (200mg/50mls) administered three times daily in conjunction with conventional iron therapy (Mojeaga group) for 2 weeks or conventional iron therapy alone without Mojeaga (standard-of-care group) for 2 weeks. Repeat hematocrit level were done 2 weeks post-initial therapy. Primary outcome measures were changes in hematocrit level and median hematocrit level at two weeks post therapy. Maternal adverse events and neonatal outcomes (birth anomalies, low birthweight, preterm rupture of membranes and preterm labor) were considered the safety outcome measures. Analysis was by intention-to-treat. RESULTS Ninety five participants were enrolled and randomly assigned to the Mojeaga group (n = 48) or standard-of-care group (n = 47). The baseline socio-demographic and clinical characteristics of the study participants were similar. At two weeks follow-up the median rise in hematocrit values from baseline (10.00±7.00% vs 6.00±4.00%;p<0.001) and median hematocrit values (31.00±2.00% vs 27.00±3.00%;p<0.001) were significantly higher in the Mojeaga group. There were no treatment-related serious adverse events, congenital anomalies or deaths in the Mojeaga group and incidence of other neonatal outcomes were similar (p>0.05). CONCLUSION Mojeaga represents a new adjuvants for standard-of-care option for patients with anemia. Mojeaga remedy is safe for treating anemia during pregnancy and puerperium without increasing the incidence of congenital anomalies, or adverse neonatal outcomes.

Lancet (London, England). 2023
Abstract
BACKGROUND Anaemia affects 46% of pregnancies in Africa; oral iron is recommended by WHO but uptake and adherence are suboptimal. We tested a single dose of a modern intravenous iron formulation, ferric carboxymaltose, for anaemia treatment in Malawian pregnant women. METHODS In this open-label, individually randomised controlled trial, we enrolled women with a singleton pregnancy of 13-26 weeks' gestation in primary care and outpatient settings across two regions in southern Malawi. Women were eligible if they had capillary haemoglobin of less than 10·0 g/dL and negative malaria rapid diagnostic test. Participants were randomised by sealed envelope 1:1. Assessors for efficacy outcomes (laboratory parameters and birthweight) were masked to intervention; participants and study nurses were not masked. Participants were given ferric carboxymaltose up to 1000 mg (given once at enrolment in an outpatient primary care setting), or standard of care (60 mg elemental iron twice daily for 90 days), along with intermittent preventive malaria treatment. The primary maternal outcome was anaemia at 36 weeks' gestation. The primary neonatal outcome was birthweight. Analyses were performed in the intention-to-treat population for mothers and liveborn neonates, according to their randomisation group. Safety outcomes included incidence of adverse events during infusion and all adverse events from randomisation to 4 weeks' post partum. The trial is registered with ANZCTR, ACTRN12618001268235. The trial has completed follow-up. FINDINGS Between Nov 12, 2018, and March 2, 2021, 21 258 women were screened, and 862 randomly assigned to ferric carboxymaltose (n=430) or standard of care (n=432). Ferric carboxymaltose did not reduce anaemia prevalence at 36 weeks' gestation compared with standard of care (179 [52%] of 341 in the ferric carboxymaltose group vs 189 [57%] of 333 in the standard of care group; prevalence ratio [PR] 0·92, 95% CI 0·81 to 1·06; p=0·27). Anaemia prevalence was numerically lower in mothers randomly assigned to ferric carboxymaltose compared with standard of care at all timepoints, although significance was only observed at 4 weeks' post-treatment (PR 0·91 [0·85 to 0·97]). Birthweight did not differ between groups (mean difference -3·1 g [-75·0 to 68·9, p=0·93). There were no infusion-related serious adverse events or differences in adverse events by any organ class (including malaria; ≥1 adverse event: ferric carboxymaltose 183 [43%] of 430 vs standard of care 170 [39%] of 432; risk ratio 1·08 [0·92 to 1·27]; p=0·34). INTERPRETATION In this malaria-endemic sub-Saharan African setting, treatment of anaemic pregnant women with ferric carboxymaltose was safe but did not reduce anaemia prevalence at 36 weeks' gestation or increase birthweight.

Intravenous Iron Compared With Oral Iron Supplementation for the Treatment of Postpartum Anemia: A Randomized Controlled Trial
Saad, A. F., Stepanek, R., Kothmann, M., Wilson-Jimenez, M., McCoy, L., Aguillon, B., Salazar, A., Saade, G. R.
Obstetrics and Gynecology. 2023;141(6):1052-1055
Abstract
Postpartum anemia is a significant maternal comorbidity that affects 50% of patients in the United States. It has been associated with maternal impaired cognition, depression, and fatigue, ultimately affecting mother–child bonding and neonatal care. Oral iron supplementation is currently the first-line treatment for women with iron-deficiency anemia postpartum. The effectiveness of oral iron is diminished by variability in absorption, discomforting side effects, and poor compliance, limitations that can be overcome with intravenous (IV) iron. However, IV iron is costly and needs to be administered under supervision in a hospital or outpatient clinical setting. We performed a pragmatic, double-blinded, feasibility randomized controlled trial of daily oral compared with IV iron administered after delivery but before hospital discharge. We found that patients randomized to IV iron had higher hemoglobin levels after 6 weeks postpartum than those randomized to oral iron. Our trial shows that it is feasible to administer IV iron during the delivery admission and that larger multicenter clinical trials are warranted.

Abstract
INTRODUCTION Anemia among pregnant women is one of the major health concerns for healthcare workers. The management becomes a concern in the pregnancy where the question arises of which is better the intravenous iron sucrose or the oral ferrous sulfate tablets. To answer this, a randomized control trial comparing both the treatment options in a tertiary care government hospital was set up in the hilly terrains of India. This study discusses the effectiveness and practical aspect of using both, which seems to be the better out of both, and why. METHODS The study was conducted as a parallel-group, open-label randomized controlled trial (RCT) in the Department of Obstetrics and Gynecology of a tertiary care government hospital in India, with approximately 4,000 delivery loads annually. Ethical clearance was obtained from the institute's ethics committee (IEC), and the trial was registered with the Clinical Trial Registry of India (REF/2022/06/055013). Two hundred sixty-eight pregnant women between 18 and 45 years of age with moderate iron deficiency anemia (IDA) (hemoglobin (Hb) 7-9g/dl, microcytic-hypochromic, and serum ferritin <30ng/ml) were included in the study. Patients were randomly divided into two groups: group 1 with 134 patients to receive intravenous iron sucrose and group 2 with 134 patients to receive oral ferrous sulfate tablets. RESULTS The intravenous iron sucrose is superior in terms of tolerability and correction of iron deficiency anemia during pregnancy. CONCLUSION It yields a quicker rise in Hb and serum ferritin with no major side effects. In the difficult terrain of Himachal Pradesh, this makes IV iron sucrose a better option for anemic pregnant women who do not have easy access to health facilities resulting in a large number of them reaching hospitals with moderate to severe anemia at a later gestation.
PICO Summary
Population
Pregnant women with moderate iron deficiency anaemia (n= 268).
Intervention
Intravenous iron sucrose (n= 134).
Comparison
Oral ferrous sulfate tablets (n= 134).
Outcome
All women were followed up at four weeks after drug administration and at 36 weeks of gestation to check for the rise in serum ferritin and haemoglobin (Hb). The mean Hb after four weeks of therapy was 11.76 ± 1.29g/dl and 10.84 ± 0.67g/dl in the intravenous iron sucrose and oral ferrous sulfate group, respectively. The Hb at four weeks post-treatment was significantly higher in the intravenous group compared to the oral group. The mean Hb (g/dl) at 36 weeks of gestation was 12 ± 1.1g/dl and 11.28 ± 0.59g/dl in the intravenous iron sucrose and oral ferrous sulfate groups, respectively. The difference between the two groups was statistically significant. The rise in haemoglobin was 3.48g/dl and was significantly high in the intravenous iron sucrose group compared to the oral ferrous sulfate group which was 2.39g/dl after four weeks of treatment. The rise was 3.6g/dl and 2.82g/dl in the intravenous iron sucrose and oral ferrous sulfate group, respectively, at 36 weeks of gestation, and the difference was significant.

American journal of obstetrics & gynecology MFM. 2023;:101064
Abstract
BACKGROUND Iron deficiency anemia in pregnancy is highly prevalent and presents significant risk to patients. Initial treatment is often with oral medication. We hypothesized that intravenous ferumoxytol would result in superior treatment of anemia as compared to oral ferrous sulfate. OBJECTIVE Investigate whether two infusions of intravenous ferumoxytol are superior to the use of twice-daily oral ferrous sulfate for the treatment of iron deficiency anemia in pregnancy. STUDY DESIGN A randomized controlled trial was performed in which anemic participants (hemoglobin <11gd/L and hematocrit <33%) were allocated to receive either two infusions of 510mg of intravenous ferumoxytol approximately 7 days apart or 325mg oral ferrous sulfate twice daily from enrollment to the end of their pregnancy. Participants were randomized in a 1:1 ratio to each treatment. Our primary outcome was change in maternal hemoglobin. Secondary outcomes included maternal iron indices, maternal safety and maternal tolerability. RESULTS There were 124 participants (N = 62 per group). In the intravenous iron group, the mean change in hemoglobin was 1.86 g/dL (95% CI 1.57 g/dL - 2.14 g/dL) and in the oral group was 0.79 g/dL (95% CI 0.42 g/dL - 1.17 g/dL) (p<0.0001). The median change in ferritin between groups was 64.5 (range 31 - 364) vs 8 (range -436 - +167) (p=0.0001). The median change in iron between groups was also statistically significant with 47.5 ug/dL (range -133 ug/dL - +664 ug/dL) in the intravenous group vs 8.5 ug/dL (range -313 ug/dL -+437 ug/dL) in the oral iron group (p=0.001). CONCLUSION Intravenous ferumoxytol was well-tolerated, and it was associated with statistically significant increases in maternal hemoglobin, hematocrit, iron, and ferritin compared to oral ferrous sulfate.
