Intravenous ferric carboxymaltose versus oral ferrous sulphate for the treatment of moderate to severe postpartum anaemia in Nigerian women (IVON-PP): protocol for an open-label randomised controlled type 1 hybrid effectiveness-implementation trial.

INTRODUCTION: Postpartum anaemia is often caused by iron deficiency with onset during the antepartum period and can be exacerbated by excessive blood loss at birth. Its prevalence is estimated as 50-80% in low-income and middle-income countries. It poses adverse consequences on the mother and negatively impacts her ability to care for her newborn. Prompt treatment of postpartum anaemia is thus important. Adherence to oral iron is reportedly low in Nigeria due to its side effects and forgetfulness by the mothers. Intravenous iron such as ferric carboxymaltose, given as a single dose, might help overcome adherence issues, but investigation in a high-quality randomised control trial in Nigeria is first required while evaluation of challenges around its implementation is also warranted. OBJECTIVE: To determine the clinical effectiveness, tolerability and safety, of using intravenous ferric carboxymaltose (intervention) vs oral ferrous sulphate (control) for treating moderate to severe iron deficiency anaemia in postpartum women and to evaluate implementation of ferric carboxymaltose in treating postpartum anaemia in Nigeria. METHODS AND ANALYSIS: This study is an open-label randomised controlled trial with a concurrent implementation study. It is a hybrid type 1 effectiveness-implementation design conducted in four states across Northern and Southern Nigeria. A total of 1400 eligible and consenting women with postpartum moderate to severe anaemia (haemoglobin concentration <100 g/L) will be randomised to intravenous ferric carboxymaltose; a single dose at 20 mg/kg to a maximum of 1000 mg infusion administered at enrolment (intervention) or oral ferrous sulphate; 200 mg (65 mg elemental iron) two times per day from enrolment until 6 weeks postpartum (control). The primary outcome, proportion of participants who are anaemic (Hb <110 g/L) at 6 weeks postpartum will be analysed by intention-to-treat. Haemoglobin concentration, full blood count, serum iron, serum ferritin, transferrin saturation and total iron binding capacity will be measured at specific intervals. Implementation outcomes such as acceptability and feasibility of using ferric carboxymaltose for postpartum anaemia treatment in Nigeria will be assessed. ETHICS AND DISSEMINATION: This study is approved by the ethics committee of the teaching hospitals, Ministry of Health of the four states as required, National Health Research Ethics Committee and the drug regulatory agency, National Agency for Food and Drug Administration and Control (NAFDAC). Findings of this research will be presented at conferences and will be published in international peer-reviewed journals and shared with stakeholders within and outside Nigeria. TRIAL REGISTRATION NUMBER: International standard randomised controlled trial number: ISRCTN51426226.

Recovery of left ventricular systolic function in peripartum cardiomyopathy: an observational study from rural Tanzania.

BACKGROUND: The aim of this study was to evaluate the recovery rate of the left ventricular systolic function of women diagnosed with peripartum cardiomyopathy receiving specialized care in rural Tanzania. METHODS: In this observational study, women diagnosed with peripartum cardiomyopathy at a referral center in rural Tanzania between December 2015 and September 2021 were included. Women diagnosed between February and September 2021 were followed prospectively, those diagnosed between December 2015 and January 2021 were tracked back for a follow-up echocardiography. All participants received a clinical examination, a comprehensive echocardiogram, and a prescription of guideline-directed medical therapy. The primary outcome was recovery of the left ventricular systolic function (left ventricular ejection fraction > 50%). RESULTS: Median age of the 110 participants was 28.5 years (range 17-45). At enrolment, 49 (45%) participants were already on cardiac medication, 50 (45%) had severe eccentric hypertrophy of the left ventricle, and the median left ventricular ejection fraction was 30% (range 15-46). After a median follow-up of 8.98 months (IQR 5.72-29.37), 61 (55%) participants were still on cardiac medication. Full recovery of the left ventricular systolic function was diagnosed in 76 (69%, 95% CI 59.6-77.6%) participants. In the multivariate analysis, a higher left ventricular ejection fraction at baseline was positively associated with full recovery (each 5% increase; OR 1.7, 95% CI 1.10-2.62, p = 0.012), while higher age was inversely associated (each 10 years increase; OR 0.40, 95% CI 0.19-0.82, p = 0.012). CONCLUSION: Left ventricular systolic function recovered completely in 69% of study participants with peripartum cardiomyopathy from rural Tanzania under specialized care.

Guyton perspective in managing peripartum cardiomyopathy patient with pulmonary edema: a case report.

BACKGROUND: Peripartum cardiomyopathy (PPCM) is a potentially life-threatening pregnancy-related condition characterized by left ventricular dysfunction and heart failure, typically occurring in the peripartum period. Individuals with a history of preeclampsia and hypertension are particularly prone to developing PPCM. Recent research suggests that the condition may be triggered by vascular dysfunction influenced by maternal hormones in the late stages of gestation. The onset of left heart failure results in decreased cardiac output, leading to insufficient perfusion, which in turn, contributes to pulmonary edema and exacerbates tissue hypoxia. This cardiovascular response activates the neurohumoral system, causing peripheral vasoconstriction and elevating both mean capillary filling pressure (MCFP) and central venous pressure (CVP). Early administration of furosemide reduces volume overload due to negative cumulative fluid balance gaining and vasodilation, which increases the velocity of intravascular refilling and causes interstitial edema to resolve. This will decrease interstitial fluid pressure, resulting in decreased mechanical compression to systemic capillary and systemic vein pressure, thus decreasing MCFP and CVP subsequently. Reduced CVP also contributes to increased venous return by decreasing the gradient pressure between MCFP and CVP, resulting in increased cardiac output (CO) and improved tissue oxygenation. CASE: A 33-year-old Asian woman, para 3 at full term pregnancy, admitted to the intensive care unit (ICU) after c-section and tubectomy due to shortness of breath and palpitation. Based on history taking, physical examination and echocardiography the patient fulfilled the criteria of PPCM which was also complicated by pulmonary edema. Despite impending respiratory failure, the patient rejected intubation and continuous positive airway pressure (CPAP), and was given oxygen supplementation through nasal cannula. Furosemide was given rapidly continued by maintenance dose and CVP was monitored. Antihypertensive drug, anticoagulants, and bromocriptine were also administered. After achieving negative cumulative fluid balance the patient's symptoms resolved and was discharged one week later. CONCLUSION: There is a correlation between negative cumulative fluid balance and reduced central venous pressure after early furosemide therapy. Suspicion for PPCM should not be lowered in the presence of preeclampsia, it could delay appropriate treatment and increase the mortality.

Predictive modeling of postpartum blood pressure spikes.

BACKGROUND: Hypertensive disorders of pregnancy are one of the leading causes of maternal morbidity and mortality worldwide. Management of these conditions can pose many clinical dilemmas and can be particularly challenging during the immediate postpartum period. Models for predicting and managing postpartum hypertension are necessary to help address this clinical challenge. OBJECTIVE: This study aimed to evaluate predictive models of blood pressure spikes in the postpartum period and to investigate clinical management strategies to optimize care. STUDY DESIGN: This was a retrospective cohort study of postpartum women who participated in remote blood pressure monitoring. A postpartum blood pressure spike was defined as a blood pressure measurement of ≥140/90 mm Hg while on an antihypertensive medication and a blood pressure measurement of ≥150/100 mm Hg if not on an antihypertensive medication. We identified 3 risk level patient clusters (low, medium, and high) when predicting patient risk for a blood pressure spike on postpartum days 3 to 7. The variables used in defining these clusters were peak systolic blood pressure before discharge, body mass index, patient systolic blood pressure per trimester, heart rate, gestational age, maternal age, chronic hypertension, and gestational hypertension. For each risk cluster, we focused on 2 treatments, namely (1) postpartum length of stay (<3 days or ≥3 days) and (2) discharge with or without blood pressure medications. We evaluated the effectiveness of the treatments in different subgroups of patients by estimating the conditional average treatment effect values in each cluster using a causal forest. Moreover, for all patients, we considered discharge with medication policies depending on different discharge blood pressure thresholds. We used a doubly robust policy evaluation method to compare the effectiveness of the policies. RESULTS: A total of 413 patients were included, and among those, 267 (64.6%) had a postpartum blood pressure spike. The treatments for patients at medium and high risk were considered beneficial. The 95% confidence intervals for constant marginal average treatment effect for antihypertensive use at discharge were -3.482 to 4.840 and - 5.539 to 4.315, respectively; and for a longer stay they were -5.544 to 3.866 and -7.200 to 4.302, respectively. For patients at low risk, the treatments were not critical in preventing a blood pressure spike with 95% confidence intervals for constant marginal average treatment effect of 1.074 to 15.784 and -2.913 to 9.021 for the different treatments. We considered the option to discharge patients with antihypertensive use at different blood pressure thresholds, namely (1) ≥130 mm Hg and/or ≥80 mm Hg, (2) ≥140 mm Hg and/or ≥90 mm Hg, (3) ≥150 mm Hg and/or ≥ 100 mm Hg, or (4) ≥160 mm Hg and/or ≥ 110 mm Hg. We found that policy (2) was the best option with P<.05. CONCLUSION: We identified 3 possible strategies to prevent outpatient blood pressure spikes during the postpartum period, namely (1) medium- and high-risk patients should be considered for a longer postpartum hospital stay or should participate in daily home monitoring, (2) medium- and high-risk patients should be prescribed antihypertensives at discharge, and (3) antihypertensive treatment should be prescribed if patients are discharged with a blood pressure of ≥140/90 mm Hg.

Posterior reversible encephalopathy syndrome in a patient with late postpartum eclampsia.

RATIONALE: Posterior reversible encephalopathy syndrome (PRES) is a rare complication commonly associated with headache and acute changes in blood pressure that results from a variety of causes, culminating in vasogenic cerebral edema in the occipital and parietal lobes of the brain. PATIENT CONCERNS: We report here a woman who suffered from headache, generalized tonic-clonic seizures, and cortical blindness in the late postpartum period. DIAGNOSES: Posterior reversible encephalopathy syndrome. INTERVENTIONS: The patient was treated with amlodipine besylate tablets for hypertension, dehydration with mannitol and glycerin fructose, and antispasmodic treatment with sodium valproate and oxcarbazepine. OUTCOMES: On day 2, the patient became conscious, headache and vision improved. One week later, symptoms and signs disappeared, blood pressure returned to normal, and brain MRI lesions disappeared in re-examination. LESSONS: Eclampsia associated with PRES is reversible in most cases, but it is a serious and potentially life-threatening obstetric emergency. If adequate treatment is provided in a timely manner, most women will make a full recovery. Attention needs to be paid to timely and adequate treatment, as well as appropriate follow-up and support for patients with PRES.

Successful management of peripartum cardiomyopathy in a Kenyan setting: a case series.

Peripartum cardiomyopathy is a rare life-threatening condition occurring in previously healthy women with symptoms mimicking those of normal pregnancy and is associated with a high mortality rate. A high index of suspicion coupled with a sound understanding of the disease is crucial to correctly diagnose and manage the patients to improve final maternal outcomes. In this report, we present a total of five cases of peripartum cardiomyopathy in women aged 22 to 38 years who presented between 3 and 21 days postpartum. All patients presented with severely reduced ejection fractions indicative of heart failure and were immediately admitted to our facility. A timely diagnosis was made and patients started on a combination of antibiotics, anticoagulants, and anti-heart failure medication. Despite the severity of the disease upon presentation, early diagnosis and precise management of the disease were essential in achieving favorable patient outcomes. Therefore, this report provides crucial knowledge about the presentation and progression of peripartum cardiomyopathy and presents a treatment protocol from a Kenyan perspective that was successfully employed in the management of all five cases.

Peripartum Cardiomyopathy with the Cardiac Function Restored by Cabergoline.

Peripartum cardiomyopathy (PPCM) is a left ventricular systolic dysfunction associated with heart failure (HF) in late-term pregnancy or peripartum. A 29-year-old pregnant woman with no history of cardiac disease noted lower extremity edema around 34 weeks' gestation with significant weight gain. She delivered twins via caesarean section, and the edema regressed postpartum. On postpartum day 4, however, she experienced difficulty breathing at night and was diagnosed with HF owing to PPCM. HF treatment along with cabergoline was initiated. With low prolactin blood levels, her symptoms and cardiac function improved over time. This case demonstrated the usefulness of anti-prolactin therapy with cabergoline in PPCM.

Peripartum cardiomyopathy: a rare cause of acute heart failure.

A woman in her early 30s presented herself with acute dyspnoea and elevated D-dimers 5 weeks after delivery of her second child. Echocardiographic findings showed signs of acute left ventricular failure, and an MRI confirmed a non-ischaemic dilated left heart failure compatible with peripartum cardiomyopathy. The antihormonal therapy with bromocriptine during 6 weeks and an intensive heart failure therapy led to an amelioration of the heart function within 3 years, but full recovery was not yet observed.

[Peripartum Cardiomyopathy]. / Peripartale Kardiomyopathie.

Peripartum cardiomyopathy (PPCM) is a rare but potentially life-threatening heart disease, with onset in the last month of pregnancy or in the first months after delivery in previously heart-healthy women. PPCM patients typically present with heart failure due to left ventricular (LV) dysfunction with an LV ejection fraction (EF) < 45 %. In the last years clinical and experimental studies contributed to a better understanding of the pathophysiology and the clinical course of PPCM. In the context of oxidative stress, the nursing hormone prolactin is cleaved into a smaller antiangiogenic and proapoptotic 16k Da form, leading to myocardial dysfunction. In an animal model this can be prevented by treatment with the dopamine agonist bromocriptine, which suppresses prolactin release. This therapeutic approach was confirmed in several clinical studies. Therefore, the current guidelines recommend a treatment consisting of a heart failure treatment according to current guidelines in combination with the dopamine agonist bromocriptine. If the diagnosis is made early and the treatment is started immediately, the prognosis is good compared to other forms of cardiomyopathies, as LV function recovers in most cases.In the acute phase the severity of heart failure differs among PPCM patients. Some patients present with mild forms, whereas some PPCM patients display severely reduced LV function and cardiogenic shock. Especially the latter cases are still challenging, as treatment with ß1-adrenergic receptor agonists is associated with progression of heart failure and a worse cardiac outcome. Therefore, patients with cardiogenic shock complicating PPCM should be treated in centers experienced in mechanical circulatory support in combination with bromocriptine treatment.

Case report: the management for a gestational hypertensive woman with influenza A virus pneumonia and peripartum cardiomyopathy.

BACKGROUND: Peripartum cardiomyopathy (PPCM) is defined as an idiopathic cardiomyopathy occurring in the last month of pregnancy or the first 6 months postpartum without an identifiable cause. PPCM is suspected to be triggered by the generation of a cardiotoxic fragment of prolactin and the secretion of a potent antiangiogenic protein from the placental, but no single factor has been identified or defined as the underlying cause of the disease. Influenza virus can cause PPCM through immune-mediated response induced by proinflammatory cytokines from host immunity and endothelial cell dysfunction. We report a case in a parturient woman undergoing a cesarean delivery, who had influenza A pneumonia and PPCM. CASE PRESENTATION: A parturient woman at 40 weeks and 1 day of gestation who had experienced gestational hypertension accompanied by pulmonary edema developed hypotension after undergoing an emergency cesarean delivery. An elevation of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) was noted, and echocardiography revealed a left ventricular ejection fraction of 20%. She underwent a nasopharyngeal swab test, in which influenza A antigen was positive. She was diagnosed as having PPCM and received anti-viral treatment. After antiviral treatment, hemodynamic dysfunction stabilized. We present and discuss the details of this event. CONCLUSION: PPCM is a heart disease that is often overlooked by medical personnel. Rapid swab tests, serum creatine kinase measurement, and echocardiography are imperative diagnostic approaches for the timely recognition of virus-associated cardiomyopathy in peripartum women with influenza-like disease and worsening dyspnea, especially during the epidemic season. Prompt antiviral treatment should be considered, particularly after PPCM is diagnosed.

Implementation of a protocol for management of antepartum iron deficiency anemia: a prospective cohort study.

BACKGROUND: In randomized trials, antepartum intravenous iron sucrose is effective at improving predelivery hemoglobin in iron deficiency anemia. Yet, there is a gap between this knowledge and its implementation into care. OBJECTIVE: We aimed to determine if the implementation of a standardized protocol for the management of antepartum anemia outside of a clinical trial improves intravenous iron sucrose utilization and clinical outcomes. STUDY DESIGN: We performed a prospective cohort study evaluating the incorporation of an anemia protocol into routine clinical care for women with antepartum hemoglobin <11.0 g/dL. Our protocol, developed with multidisciplinary stakeholders, included (1) serial third trimester hemoglobin assessment, (2) oral iron supplementation for antepartum hemoglobin 9.5-11 g/dL, and (3) antepartum intravenous iron sucrose use (300 mg weekly for 3 weeks) for hemoglobin <9.5 g/dL. We compared 6-months preimplementation (January 2018 to June 2018) to 6-months postimplementation (January 2019 to June 2019). The outcomes evaluated were antepartum intravenous iron sucrose utilization, the number of intravenous iron sucrose dosages, predelivery hemoglobin, and blood transfusion. RESULTS: A total of 1423 women were included (pre=778; post=645) without significant baseline differences. The antepartum hemoglobin nadir was no different between the groups (pre: 10.2; interquartile range [9.6-10.6] vs post: 10.2; interquartile range [9.6-10.6]; P=.77). The implementation of a standardized protocol for the management of antepartum anemia was associated with 80% increased odds of receiving intravenous iron sucrose than the preimplementation group (pre: 4.8% vs post: 8.2%, P=.008; odds ratio, 1.79; 95% confidence interval, [1.16-2.77]). The implementation of a standardized protocol for the management of antepartum iron deficiency anemia was also associated with higher hemoglobin at admission for delivery (pre: 10.9; interquartile range [10.1-11.6] vs post: 11.0; interquartile range [10.3-11.7], P=.048). There were no significant differences between the groups in blood product transfusion (pre: 7.1% vs post: 5.1%, P=.13). CONCLUSION: Implementation of a standardized antepartum anemia protocol is associated with increased intravenous iron sucrose utilization and improvement in predelivery hemoglobin.

Impact of autoantibodies against the M2-muscarinic acetylcholine receptor on clinical outcomes in peripartum cardiomyopathy patients with standard treatment.

OBJECTIVES: To evaluate the impact of autoantibodies against the M2-muscarinic receptor (anti-M2-R) on the clinical outcomes of patients receiving the standard treatment for peripartum cardiomyopathy (PPCM). METHODS: A total of 107 PPCM patients who received standard heart failure (HF) treatment between January 1998 and June 2020 were enrolled in this study. According to anti-M2-R reactivity, they were classified into negative (n = 59) and positive (n = 48) groups, denoted as the anti-M2-R (-) and anti-M2-R (+) groups. Echocardiography, 6-min walk distance, serum digoxin concentration (SDC), and routine laboratory tests were performed regularly for 2 years. The all-cause mortality, cardiovascular mortality, and rehospitalisation rate for HF were compared between the two groups. RESULTS: A total of 103 patients were included in the final data analysis, with 46 in the anti-M2-R (+) group and 57 in the anti-M2-R (-) group. Heart rate was lower in the anti-M2-R (+) group than in the anti-M2-R (-) group at the baseline (102.7 ± 6.1 bpm vs. 96.0 ± 6.4 bpm, p < 0.001). The initial SDC was higher in the anti-M2-R (+) group than in the anti-M2-R (-) group with the same dosage of digoxin (1.25 ± 0.45 vs. 0.78 ± 0.24 ng/mL, p < 0.001). The dosages of metoprolol and digoxin were higher in the anti-M2-R (-) patients than in the anti-M2-R (+) patients (38.8 ± 4.6 mg b.i.d. vs. 27.8 ± 5.3 mg b.i.d., p < 0.0001, respectively, for metoprolol; 0.12 ± 0.02 mg/day vs. 0.08 ± 0.04 mg/day, p < 0.0001, respectively, for digoxin). Furthermore, there was a greater improvement in cardiac function in the anti-M2-R (-) patients than in the anti-M2-R (+) patients. Multivariate analysis identified negativity for anti-M2-R as the independent predictor for the improvement of cardiac function. Rehospitalisation for HF was lower in the anti-M2-R (-) group, but all-cause mortality and cardiovascular mortality were the same. CONCLUSIONS: There were no differences in all-cause mortality or cardiovascular mortality between the two groups. Rehospitalisation rate for HF decreased in the anti-M2-R (-) group. This difference may be related to the regulation of the autonomic nervous system by anti-M2-R.

The outcomes of pregnant and postpartum patients with cerebral venous sinus thrombosis after anticoagulant therapy.

BACKGROUND: To describe the outcome of the patients with cerebral venous sinus thrombosis (CVST) during pregnancy and postpartum treated with anticoagulant therapy. METHODS: This is a retrospective cohort study and patients with CVST were collected from October 2009 to March 2018. Patients were divided into pregnancy-related (occurred during pregnancy and postpartum) group and non-pregnancy-related. Recovery rate at 12 months after anticoagulant therapy, adverse events, characteristics of patients with poor outcomes were statistically analyzed. RESULTS: Fifty-eight pregnancy-related CVST patients (17 pregnancy and 41 postpartum) as study group and 76 non-pregnancy-related CVST women as control group were enrolled. Study group was statistically different to control group in several baseline variables. More pregnancy-related patients had modified rankin scale (mRS) = 5 (15.5% vs 11.8%, P = 8.1×10-3) before anticoagulant therapy. At 12 months heparinization, difference in recovery rate was not statistically significant (80% vs 87.5%, P = .29) between 2 groups. No differences were found of adverse events between 2 groups. Patients with poor outcomes had less sigmoid sinus thrombosis (16.7% vs 61.5%, P = .14), more coma (41.2% vs 17.2%, P = 5.2×10-7), more mRS = 4 (33.3% vs 19.2%, P = 1.63 × 10-4), more mRS = 5 (66.7% vs 9.6%, P = 1.63 × 10-4) before treatment. CONCLUSION: Pregnancy-related CVST patients had severer condition before treatment, but can achieve comparable recovery rate at 12 months after anticoagulant therapy with non-pregnancy-related women. Pregnancy-related patients with poor prognosis had less sinus sigmoid occlusion, more coma, high mRS at admission.

Risk factors for needing postpartum antihypertensive medications with hypertensive disorders: Timing of diagnosis, presence of proteinuria, and severity of disease.

OBJECTIVES: Evaluate the association between the need for post-partum antihypertensive medications in patients with hypertensive disorders of pregnancy (HDP) and the following: timing of disease onset (antepartum vs. intrapartum), presence of proteinuria, and severity of disease. STUDY DESIGN: This was a retrospective cohort study. We reviewed the charts of 204 patients diagnosed with HDP: 106 were diagnosed antepartum and 98 diagnosed intrapartum. Patients withchronichypertensionwereexcluded. MAIN OUTCOME MEASURES: The need for outpatient antihypertensive medications at time of hospital discharge was the primary outcome. We performed logistic regression of covariates and a stratified analysis for each specific HDP (gestational hypertension (GHTN), preeclampsia and preeclampsia with severe features). RESULTS: While the diagnosis of HDP in the antepartum period was a statistically significant risk factor for needing postpartum anti-hypertensive medications at discharge in bivariate analysis RR 2.07 (1.27-3.37), p = 0.001, it did not remain significant after correction for the covariates RR 1.41 (0.45-4.49), P = 0.55. However, the presence of proteinuria was an independent risk factor after logistic regression. Compared to GHTN, there was a significant difference in the need for postpartum anti-hypertensive medications in patients with preeclampsia OR 10.70 (1.54-74.42), p = 0.017 and in preeclampsia with severe features OR 112.14 (20.05-627.22), p < 0.001. CONCLUSION: Timing of onset of HDP (antepartum vs. intrapartum) was not an independent risk factor for needing antihypertensive medications postpartum. However, proteinuria and the presence of severe features were. Patients with proteinuria and those with severe disease may warrant closer surveillance in the post-partum period than those without proteinuria.

Addition of oral iron bisglycinate to intravenous iron sucrose for the treatment of postpartum anemia-randomized controlled trial.

BACKGROUND: Studies that have compared the effectiveness of oral with intravenous iron supplements to treat postpartum anemia have shown mixed results. The superiority of one mode of treatment vs the other has yet to be demonstrated. Therefore, despite guidelines and standards of care, treatment approaches vary across practices. A single 500 mg dose of iron sucrose, which is higher than what is usually administered, has not been evaluated to treat postpartum moderate to severe anemia. OBJECTIVE: This study aimed to compare the efficacy of intravenous iron sucrose alone with intravenous iron sucrose in combination with oral iron bisglycinate supplementation in treating moderate to severe postpartum anemia. STUDY DESIGN: A randomized controlled trial was conducted between February 2015 and June 2020. Women with postpartum hemoglobin level of ≤9.5 g/dL were treated with 500 mg intravenous iron sucrose after an anemia workup, which ruled out other causes for anemia. In addition to receiving intravenous iron, women were randomly allocated to receive either 60 mg of oral iron bisglycinate for 45 days or no further iron supplementation. The primary outcome was hemoglobin level at 6 weeks after delivery. Secondary outcomes were iron storage parameters and quality of life. RESULTS: Of 158 patients who participated, 63 women receiving intravenous and oral iron, and 44 women receiving intravenous iron-only, completed the study and were included in the analysis. Baseline and obstetrical characteristics were similar between the study cohorts. Although statistically significant, postpartum hemoglobin levels were only 0.4 g/dL higher in the intravenous and oral iron than intravenous iron-only cohort (12.4 g/dL vs 12.0 g/dL, respectively; P=.03), with a respective increase from baseline of 4.2 g/dL vs 3.7 g/dL (P=.03). There was no difference in the rate of women with hemoglobin level of <12.0 or 11.0 g/dL. Iron storage and health quality were not different between the cohorts. Oral iron treatment was associated with 29% rate of adverse effects. Compliance and satisfaction from treatment protocol were high in both cohorts. CONCLUSION: Intravenous 500 mg iron sucrose treatment alone is sufficient to treat postpartum anemia without the necessity of adding oral iron treatment.
