Rituximab as a treatment for refractory immune thrombocytopenia during pregnancy.

Immune thrombocytopenia (ITP) is most common in women during their reproductive years. When a low platelet count occurs for the first time during pregnancy, the differential diagnosis includes pregnancy-specific conditions. Although ITP is the most common cause of thrombocytopenia early in pregnancy, pregnancy-related thrombocytopenia develops mainly in late gestation. As maternal and neonatal outcomes are usually favourable, ITP per se is not a contraindication for pregnancy. We report the case with a literature review of patient with ITP, whose diagnosis was established in early pregnancy. This condition was refractory to first-line treatments, such as high-dose steroids and intravenous immunoglobulin and other splenectomy-sparing approaches, as rituximab, having the control been reached on the third trimester after splenectomy. Although not effective in this case, we still believe that rituximab should be considered before surgery during pregnancy.

A meta-analysis of ferric carboxymaltose versus other intravenous iron preparations for the management of iron deficiency anemia during pregnancy.

Objective: We conducted a meta-analysis of randomized clinical trials evaluating the clinical effects of ferric carboxymaltose therapy compared to other intravenous iron in improving hemoglobin and serum ferritin in pregnant women. We also assessed the safety of ferric carboxymaltose vs. other intravenous iron. Data source: EMBASE, PubMed, and Web of Science were searched for trials related to ferric carboxymaltose in pregnant women, published between 2005 and 2021. We also reviewed articles from google scholar. The keywords "ferric carboxymaltose," "FCM," "intravenous," "randomized," "pregnancy," "quality of life," and "neonatal outcomes" were used to search the literature. The search was limited to pregnant women. Selection of studies: Studies related to ferric carboxymaltose in pregnancy were scanned. Observational studies, review articles, and case reports were excluded. Randomized studies in pregnant women involving ferric carboxymaltose and other intravenous iron formulations were shortlisted. Of 256 studies, nine randomized control trials were selected. Data collection: Two reviewers independently extracted data from nine selected trials. Data synthesis: The final effect size for increase in hemoglobin after treatment was significant for ferric carboxymaltose vs. iron sucrose/iron polymaltose (standard mean difference 0.89g/dl [95% confidence interval 0.27,1.51]). The final effect size for the increase in ferritin after treatment was more for ferric carboxymaltose vs. iron sucrose/iron polymaltose (standard mean difference 22.53µg/L [-7.26, 52.33]). No serious adverse events were reported with ferric carboxymaltose or other intravenous iron. Conclusion: Ferric carboxymaltose demonstrated better efficacy than other intravenous iron in increasing hemoglobin and ferritin levels in treating iron deficiency anemia in pregnant women.

The Experience of Anaemia and Ingesting Oral Iron Supplementation in Pregnancy: A Qualitative Study.

INTRODUCTION: The objective of this study was to understand the experience of iron deficiency anaemia requiring oral iron in pregnancy and the factors affecting compliance with oral iron supplementation. Participants' understanding regarding the possible consequences of anaemia in pregnancy was also explored. Feedback on a proposed randomised controlled trial of daily versus alternate day oral iron in pregnancy was sought. MATERIALS & METHODS: Following ethical approval, fourteen semi-structured one-to-one interviews were carried out using an interview tool with open-ended questions. Recruitment was carried out through social media and from an antenatal out-patient setting. Interviews were audio-recorded, transcribed and analysed thematically. RESULTS: Fatigue emerged as a predominant and troubling symptom. Awareness was often highlighted through friends/family and from healthcare professionals, particularly in first pregnancies. Knowledge surrounding the potential short-term and long-term adverse consequences of untreated anaemia however was limited. Gastro-intestinal side-effects, a previous experience of poor tolerance and forgetfulness all negatively impacted compliance with oral iron supplementation in pregnancy. Routine, a perceived improvement in fatigue with supplementation and reduced dose frequency recurred as themes which positively affected compliance. Pregnancy as a motivating factor recurred as a theme in analysis. The role of diet was felt to be important. Knowledge of iron-rich foods and absorption aids and inhibitors was good, but practice on optimal ingestion of oral iron supplementation varied. Feedback on trial acceptability was positive with the benefit of extra supportive care noted. Incorporating study visits with routine care was advised in view of time constraints. This area of research was perceived as important. CONCLUSION: In order to successfully reduce the rates of iron deficiency anaemia in pregnancy, it is crucial that all factors affecting compliance with oral iron are considered. Providing women with the important information on the possible consequences of sub optimally treated anaemia may help to improve this public health issue.

Clinical outcome post treatment of anemia in pregnancy with intravenous versus oral iron therapy: a systematic review and meta-analysis.

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).

The incidence, complications, and treatment of iron deficiency in pregnancy.

Iron deficiency and/or iron deficiency anemia (IDA) complicate nearly 50% of pregnancies globally, negatively impacting both maternal and fetal outcomes. Iron deficiency can cause a range of symptoms that range from aggravating to debilitating including fatigue, poor quality of life, pagophagia, and restless leg syndrome. Iron deficiency and IDA are also associated with maternal complications including preterm labor, increased rates of cesarean delivery, postpartum hemorrhage, and maternal death. Fetal complications include increased rates of low birth weight and small for gestational age newborns. Prenatal maternal anemia has also been associated with autism spectrum disorders in the neonate, although causation is not established. Deficiency in the newborn is associated with compromised memory, processing, and bonding, with some of these deficits persisting into adulthood. Despite the prevalence and consequences associated with iron deficiency in pregnancy, data show that it is routinely undertreated. Due to the physiologic changes of pregnancy, all pregnant individuals should receive oral iron supplementation. However, the bioavailability of oral iron is poor and it is often ineffective at preventing and treating iron deficiency. Likewise, it frequently causes gastrointestinal symptoms that can worsen the quality of life in pregnancy. Intravenous iron formulations administered in a single or multiple dose series are now available. There is increasing data suggesting that newer intravenous formulations are safe and effective in the second and third trimesters and should be strongly considered in pregnant individuals without optimal response to oral iron repletion.

Screening, Treatment, and Monitoring of Iron Deficiency Anemia in Pregnancy and Postpartum.

Iron deficiency anemia is the most prevalent form of anemia worldwide. In the United States, clinicians routinely screen for iron deficiency anemia upon initiation of prenatal care, at the start of the third trimester, and prior to birth. Treatment of iron deficiency anemia generally begins with oral supplementation of elemental iron, which is associated with adverse gastrointestinal effects. These adverse effects can decrease adherence, leading to subtherapeutic treatment. Newer evidence highlights the benefits of early screening for iron deficiency before the onset of anemia, as well as the use of intravenous iron to expedite the treatment of iron deficiency anemia. More research is needed on the potential consequences of over-supplementation and iron deficiency without anemia to guide treatment. This article reviews the evidence for best practices for screening, treatment, and continued monitoring of iron deficiency anemia during pregnancy and postpartum. Maternal, fetal, and neonatal implications are reviewed, as well as the risks and benefits of treatment options. Finally, an evidence-based algorithm is proposed to guide clinicians on continued monitoring after treatment.

Desiderosmia: a manifestation of iron deficiency in pregnancy.

A pregnant woman in her 20s presented with an excessive desire to smell a specific household cleaning product. She was found to have severe iron deficiency anaemia and her symptoms resolved following intravenous iron supplementation. She described symptoms of fatigue, shortness of breath and olfactory cravings. The specific scent could not be replicated with other smells and the woman had to significantly modify her lifestyle to accommodate the excessive desire. She had a similar experience during her prior pregnancy which resolved after the correction of severe iron deficiency anaemia. This unique symptom has been described as desiderosmia: iron deficiency manifesting as olfactory cravings. This underappreciated but useful symptom is defined as a separate entity to pica, as there is an absence of desire to ingest the product. Desiderosmia can harm mother and baby through inhalation of potentially harmful fumes; hence, women who describe this symptom should be assessed for iron deficiency anaemia.

Is every other day iron supplementation effective for the treatment of the iron deficiency anemia in pregnancy?

AIM: To understand if every other day iron supplementation may be as effective as daily iron intake in anemic pregnant women. METHODS: This case-control study was conducted at a tertiary hospital in Turkey. The study randomly categorized women into two groups as daily intake (n = 124) vs every other day intake (n = 140) of 100 mg daily oral ferrous fumarate. The numbers of women recruited from the study were 13 and 34 in two groups. Thus, for analysis, there were 111 women in the daily group and 106 women in the other group. The current study obtained hemoglobin (Hb) and ferritin levels two times to evaluate the effects of treatment, noting initial levels before drug administration, and a second blood sample was obtained after two months. Two groups were compared according to the increase in Hb and ferritin levels. The study asked the women whether they experienced gastrointestinal side effects. RESULTS: The ferritin levels increased 4.9 ± 4.2 ng/mL in the daily intake group and 3.9 ± 2.9 ng/mL in every other day group (p = .215). The Hb increased 1.4 ± 0.7 g/dL in the daily intake group and 1.6 ± 0.6 g/dL in the other group (p = .021). Gastrointestinal side effects appeared in 47 (17.8%) out of 264 women. The rate of gastrointestinal side effect was lower in every other day group (41.4% vs 15.1%, p = .0057). CONCLUSION: Every other day iron supplementation is as effective as daily intake for treating iron deficiency anemia with lesser gastrointestinal side effects during pregnancy.

Rebound of platelet count in a patient with type 2 calreticulin-mutant essential thrombocythemia in the postpartum period: A case report.

INTRODUCTION: Essential thrombocythemia (ET) is an uncommon myeloproliferative neoplasm. It is more common in females; 20% of them are below 40 years old. The optimal management of ET during pregnancy and postpartum periods is still not well established. PATIENT CONCERN: We report a case of a young lady with type 2 calreticulin-mutant ET who developed a marked rebound in her platelet count (reaching 2030 × 103/µL) 2 weeks after premature delivery of her baby (24th week of gestation). She was on Pegylated Interferon alfa 2-a during pregnancy (her platelet was around 500 × 103/µL during the second trimester), but she had stopped it on her own from the 20th week of gestation. DIAGNOSIS: Postpartum rebound of platelet count due to medication non-compliance. INTERVENTION AND OUTCOME: We resumed her regular Pegylated Interferon, and subsequently, her platelet count reduced dramatically within 4 weeks to an acceptable level (684 × 103 /µL). CONCLUSION: The guideline is still not well-established regarding the optimal approach for postpartum rebound of platelet count in patients with ET. It is still unclear if the platelet count will fall spontaneously without intervention after the rebound phase. Further research is required to establish the optimal management of ET during the postpartum phase. This case emphasizes the importance of platelet count follow-up during the postpartum period and outlines our management approach in such cases.

Oral Iron Supplementation in Pregnancy: Current Recommendations and Evidence-Based Medicine.

OBJECTIVE: To review the evidence about universal iron supplementation in pregnancy to prevent maternal anemia. METHODS: Bibliographic research of randomized and controlled clinical trials, meta-analyses, systematic reviews, and clinical guidelines, published between August 2009 and August 2019, using the MeSH terms: iron; therapeutic use; pregnancy; anemia, prevention and control. RESULTS: We included six clinical guidelines, three meta-analyses and one randomized controlled clinical trial. DISCUSSION: Most articles point to the improvement of hematological parameters and reduction of maternal anemia risk, with supplementary iron. However, they do not correlate this improvement in pregnant women without previous anemia with the eventual improvement of clinical parameters. CONCLUSION: Universal iron supplementation in pregnancy is controversial, so we attribute a SORT C recommendation strength.

OBJETIVO: Rever a evidência sobre a necessidade de suplementação universal de ferro na gravidez para prevenção de anemia materna. MéTODOS: Pesquisa bibliográfica de ensaios clínicos aleatorizados e controlados, metanálises, revisões sistemáticas e normas de orientação clínica, publicados entre agosto de 2009 e agosto de 2019, utilizando os termos MeSH: iron, terapêuticas use; pregnancy; anemia, preventivos and control. RESULTADOS: Incluímos seis normas de orientação clínica, três metanálises e um ensaio clínico randomizado e controlado. DISCUSSãO: A maioria dos artigos aponta para a melhoria dos parâmetros hematológicos e redução do risco de anemia materna por meio da suplementação com ferro. Todavia, eles não correlacionam a melhoria destes parâmetros em grávidas sem anemia prévia com a eventual melhoria de parâmetros clínicos. CONCLUSõES: A suplementação universal com ferro na gravidez é controversa, pelo que atribuímos uma força de recomendação SORT C.

Iron Deficiency Anemia in Pregnancy.

Anemia is defined as a low red blood cell count, a low hematocrit, or a low hemoglobin concentration. In pregnancy, a hemoglobin concentration of less than 11.0 g/dL in the first trimester and less than 10.5 or 11.0 g/dL in the second or third trimester (depending on the guideline used) is considered anemia. Anemia is the most common hematologic abnormality in pregnancy. Maternal anemia is associated with adverse fetal, neonatal and childhood outcomes, but causality is not established. Maternal anemia increases the likelihood of transfusion at delivery. Besides hemodilution, iron deficiency is the most common cause of anemia in pregnancy. The American College of Obstetricians and Gynecologists recommends screening for anemia with a complete blood count in the first trimester and again at 24 0/7 to 28 6/7 weeks of gestation. Mild anemia, with a hemoglobin of 10.0 g/dL or higher and a mildly low or normal mean corpuscular volume (MCV) is likely iron deficiency anemia. A trial of oral iron can be both diagnostic and therapeutic. Mild anemia with a very low MCV, macrocytic anemia, moderate anemia (hemoglobin 7.0-9.9 g/dL) or severe anemia (hemoglobin 4.0-6.9 g/dL) requires further investigation. Once a diagnosis of iron deficiency anemia is confirmed, first-line treatment is oral iron. New evidence suggests that intermittent dosing is as effective as daily or twice-daily dosing with fewer side effects. For patients with iron deficiency anemia who cannot tolerate, cannot absorb, or do not respond to oral iron, intravenous iron is preferred. With contemporary formulations, allergic reactions are rare.

RAPIDIRON: Reducing Anaemia in Pregnancy in India-a 3-arm, randomized-controlled trial comparing the effectiveness of oral iron with single-dose intravenous iron in the treatment of iron deficiency anaemia in pregnant women and reducing low birth weight deliveries.

BACKGROUND: Anaemia is a worldwide problem and iron deficiency is the most common cause. In pregnancy, anaemia increases the risk of adverse maternal, foetal and neonatal outcomes. India's anaemia rate is among the highest in the world with India's National Family Health Survey indicating over 50% of pregnant women were affected by anaemia. India's Anaemia Mukt Bharat-Intensified National Iron Plus Initiative aims to reduce the prevalence of anaemia among reproductive-age women, adolescents and children by 3% per year and facilitate the achievement of a Global World Health Assembly 2025 objective to achieve a 50% reduction of anaemia among women of reproductive age. However, preliminary results of the NFHS-5 survey completed in 2020 indicate that anaemia rates are increasing in some states and these targets are unlikely to be achieved. With oral iron being the first-line treatment for iron deficiency anaemia (IDA) in pregnancy, these results are likely to be impacted by the side effects, poor adherence to tablet ingestion and low therapeutic impact of oral iron. These reports suggest a new approach to treating IDA, specifically the importance of single-dose intravenous iron infusions, may be the key to India effectively reaching its targets for anaemia reduction. METHODS: This 3-arm, randomized controlled trial is powered to report two primary outcomes. The first is to assess whether a single dose of two different intravenous formulations administered early in the second trimester of pregnancy to women with moderate IDA will result in a higher percentage of participants achieving a normal for pregnancy Hb concentration at 30-34 weeks' gestation or just prior to delivery when compared to participants taking standard doses of oral iron. The second is a clinical outcome of low birth weight (LBW) (< 2500 g), with a hypothesis that the risk of LBW delivery will be lower in the intravenous iron arms when compared to the oral iron arm. DISCUSSION: The RAPIDIRON trial will provide evidence to determine if a single-dose intravenous iron infusion is more effective and economically feasible in reducing IDA in pregnancy than the current standard of care.

A randomized controlled trial comparing the efficacy, tolerability, and cost of oral iron preparations in iron-deficiency anemia in pregnancy.

OBJECTIVE: To evaluate the efficacy, tolerability, and cost of four commonly prescribed oral iron preparations: ferrous sulfate (FS), ferrous fumarate (FF), ferrous ascorbate (FA), and carbonyl iron (CI) in the treatment of iron-deficiency anemia (IDA) in pregnant women. METHODS: It was a prospective, randomized, open-label, blinded endpoint (PROBE) design with four parallel active control groups: FS, FF, FA, CI. The primary outcome was the proportion of participants becoming non-anemic (Hb ≥ 11 g%) at the end of the study period. The secondary outcomes were the proportion of participants achieving normal red blood corpuscular indices such as mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration; the proportion of participants achieving normal iron indices such as serum iron, serum ferritin, total iron-binding capacity, and transferrin saturation; and comparison of incidence of any adverse events between treatment groups and comparison of costs of individual drug therapy between treatment groups. RESULTS: One hundred and twenty patients were randomized to four different groups (n = 30). The results of the present study show that all the four iron salts at the dose of 200 mg elemental iron per day were equally effective in improving hemoglobin concentration and other hematological parameters. The adverse effects were more common in the FF group (56.7%). The pharmacoeconomic analysis showed that all the drugs are equally cost-effective. CONCLUSION: To conclude from the results of the present study, it can be said that FS, FF, FA, and CI are equally effective in treating IDA and they can be prescribed interchangeably.

Coronavirus disease 2019 (COVID-19) in a pregnant women with treatment resistance thrombocytopenic purpura with and suspicion to HELLP syndrome: a case report.

BACKGROUND: Coronavirus disease 2019 (COVID-19) still is a global emergency. According to the studies, pregnant women are of the at risk populations and any underlying disease(s) might even worsen their condition. The aim of this study is reporting a complex case of immune thrombocytopenic purpura (ITP) during pregnancy who has been diagnosed with COVID-19 as well as suspicion of HELLP syndrome. CASE PRESENTATION: A 24-year-old woman with a platelet count of 6000/mL and resistance to conventional therapies was referred. A day after starting 0.5 g/day of methylprednisolone for her, fever and a decrease in SpO2 presented. According to the paraclinical investigations, COVID-19 was diagnosed and the conventional COVID-19 treatments started for her (the methylprednisolone pulse stopped). Due to the increased liver enzymes and low platelet count, with suspicion of HELLP syndrome, cesarean section surgery was performed which resulted in a healthy neonate. Then, the methylprednisolone pulse was restarted for and she developed an increase in the platelet count. CONCLUSION: It is not clear how COVID-19 and pregnancy affected the patient's condition and the underlying disease; however, it seems the delivery and/or restarting the methylprednisolone pulses caused improvement in her condition.

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).

The effect of Lactiplantibacillus plantarum 299v together with a low dose of iron on iron status in healthy pregnant women: A randomized clinical trial.

INTRODUCTION: Iron deficiency during pregnancy is a global health problem and is associated with adverse pregnancy outcomes. The aim of this randomized, double-blind, placebo-controlled study was to evaluate the effect of Lactiplantibacillus plantarum 299v (Lp299v, 1010 colony forming units), 4.2 mg iron, 12 mg ascorbic acid and 30 µg folic acid (Lp) on iron status in healthy, non-anemic, pregnant Swedish women. MATERIAL AND METHODS: A total of 326 women were randomized to receive Lp (n = 161) or placebo (n = 165) twice daily from gestational week 10-12 until end of pregnancy or until the potential start of iron therapy. The primary endpoint was serum ferritin at week 28. RESULTS: Intake of Lp attenuated the decrease in serum ferritin from baseline to week 28 (p = 0.003) and week 35 (p Ë‚ 0.001) and resulted in reduced prevalence of iron deficiency (59% vs 78%, p = 0.017) and iron deficiency anemia (7.4% vs 21%, p = 0.023) at week 35. Intake of Lp also resulted in beneficial effects on the soluble transferrin receptor (p = 0.011) and total body iron (p Ë‚ 0.001) at week 35. Gestational length and birthweight were comparable between groups. The proportion of women reporting adverse events during the study was comparable between groups. CONCLUSIONS: Intake of Lp from early pregnancy was safe, attenuated the loss of iron stores and improved iron status in healthy pregnant women.

Accidentally discovered high INR in pregnancy unmasks an inherited factor VII (FVII) deficiency that is paradoxically associated with thrombotic tendency.

A 32-year-old multiparous obese woman was referred to our center at 37 weeks of twin gestation. She was referred for birth planning following an accidentally discovered high international normalised ratio (INR) in routine preoperative labs. Her history was significant for recurrent pregnancy-associated deep venous thrombosis as well as two early pregnancy losses. Further work-up revealed transaminitis, mild splenomegaly and high lupus anticoagulant titre. A multidisciplinary team of physicians from the high-risk pregnancy, anaesthesiology, haematology, gastroenterology and hepatology departments put a management plan; it culminated into uncomplicated delivery of the patient by repeated caesarian section. The team was also able to figure out the cause of the patient's high INR that is associated with thrombophilia rather than haemophilia.

Intravenous ferric derisomaltose for the treatment of iron deficiency anemia.

Intravenous (IV) iron is the therapy of choice when oral iron is ineffective or poorly tolerated, yet use has been limited by fears of hypersensitivity reactions (HSRs). Newer formulations that bind iron more tightly and release it more slowly have made the risk of serious or severe HSRs very low. One such formulation, ferric derisomaltose, has been approved in the United States for delivery of 1000 mg iron in a single IV infusion. Ferric derisomaltose rapidly repletes iron parameters with low rates of serious or severe HSRs. Single-infusion iron repletion offers convenience, eliminates adherence concerns, and reduces healthcare resource utilization.
