RESUMEN

INTRODUCTION: Up to 24.2% Malaysians are estimated to be affected by anaemia. Iron deficiency is the most common nutritional deficiency leading to anaemia. Oral iron therapy may not be well tolerated or efficient. Ferric carboxymaltose (FCM), a non-dextran intravenous iron formulation, may be an appealing alternative for iron replacement therapy. This retrospective study aimed to investigate the efficacy and safety of intravenous FCM infusion for the management of iron deficiency anaemia in a single centre in Malaysia. MATERIALS AND METHODS: All patients who received at least one dose of 500 mg intravenous FCM infusion from January to December 2023 in Bukit Tinggi Medical Centre (BTMC) were identified from the electronic medical record database. Inclusion criteria were patients: (1) ≥ 14 years old and (2) with iron deficiency anaemia. The primary outcome was the mean change in haemoglobin level before treatment and 30 day after treatment. Secondary outcomes included reasons for intravenous FCM infusion, median dose, adverse drug reactions, mean change in haemoglobin levels for different subgroups and percentage of patients with normalised haemoglobin after treatment. The efficacy outcome was analysed using per-protocol analysis while the safety outcome used intention-to-treat analysis. Paired t-test was used to compare the mean difference between the haemoglobin measurements before and 30-day after treatment. RESULTS: A total of 144 administrations were given to 141 patients requiring intravenous iron replacement therapy during the 1-year study period in BTMC. Intravenous FCM infusion was administered for the management of iron deficiency related to: (1) increased blood loss, including menorrhagia, haemorrhoids and GI-related surgery, (2) low iron intake, including poor nutrition and gastrointestinalrelated malabsorption and (3) haematological disorders, including autoimmune haemolytic anaemia, myelodysplastic syndrome, diffuse large B-cell lymphoma and idiopathic thrombocytopaenia purpura. The median dose of intravenous FCM infusion was 1000 mg. At 30 day post-infusion, the mean haemoglobin level increased significantly from 8.9 g/L to 11.6 g/L (p < 0.05), an increase of 2.68 g/L (95% CI: 2.45 - 2.90 g/L). No adverse drug reactions were reported. Subgroup analysis showed that patients with haematological disorders had significantly higher improvement in haemoglobin levels after intravenous iron infusion compared to those without. At 7-day, 14-day, 21-day post-infusion, 33% (33/99), 34% (34/99) and 36% (36/99) patients had a normalised haemoglobin level, respectively. The proportion of patients with a normalised haemoglobin level increased to 36% (36/99) and 42% (42/99) at 30-day and 90-day post-infusion. CONCLUSION: Within the limit of this single-centre retrospective study, intravenous FCM infusion was well tolerated and effective in increasing the haemoglobin level among patients with iron deficiency anaemia.

RESUMEN

BACKGROUND: Treatment of end stage renal disease (ESRD) is based on preserving renal functions. Since renal anemia is frequently detected, we use parenteral iron treatments in patients with chronic kidney disease (CKD). However, there need to be more precise and sufficient studies on the effect of these treatments on the rate of decrease in the glomerular filtration rate (GFR). Therefore, we conducted a study comparing the rates of change in renal function in patients who had used parenteral iron for at least five years. METHODS: Our study is a retrospective cohort study, and 180 patients with CKD (86 women, 94 men, mean age: 63.5 ± 11.4 years) who had been followed and treated in nephrology outpatient clinics for at least five years and met the study criteria were included in the study. Patients were divided into three groups for iron therapy: not receiving iron therapy, iron carboxy maltose (ICM), and iron sucrose (IS) parenterally. Each group consisted of 60 people. The first and last creatinine and GFR values were compared for a 5-year follow-up in each group. RESULTS: There was no significant difference between the two groups, those using and those not using iron, regarding creatinine increase and GFR decrease rate. Additionally, no significant difference was detected in the GFR decline rates of patients using ICM and IS. CONCLUSIONS: This study reduces the concerns that correcting anemia through parenteral iron therapy in patients with CKD may harm renal function.

RESUMEN

Anemia, particularly iron deficiency anemia (IDA), is a prevalent health issue globally and in Saudi Arabia, especially among young adult females. This study investigates the association between anemia and academic achievement among female students at the Female Health Campus of Jazan University, Jazan, Saudi Arabia. This cross-sectional study included 118 randomly selected participants aged 18-22. A validated questionnaire was administered to the study participants. The participants underwent blood tests for complete blood count (CBC) parameters and iron profile analysis. The study reported that 52.5% of the female students had anemia and low serum iron levels. Regarding academic performance, significant positive correlations were found between various CBC parameters including white cell count, hemoglobin, hematocrit, mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration, and serum iron. However, no significant correlations were observed between red blood cell count and platelet count with academic performance. Demographic variables were also associated with a higher odds ratio of anemia. The study highlights the prevalence of anemia among female students and its potential impact on academic achievement. The current study underscores the importance of addressing anemia in young adult females and implementing appropriate interventions to improve their educational outcomes.


L'anémie, en particulier l'anémie ferriprive (IDA), est un problème de santé répandu dans le monde et en Arabie Saoudite, en particulier chez les jeunes femmes adultes. Cette étude examine l'association entre l'anémie et la réussite scolaire chez les étudiantes du Campus de santé féminine de l'Université de Jazan, Jazan, Arabie Saoudite. Cette étude transversale a inclus 118 participants sélectionnés au hasard âgés de 18 à 22 ans. Un questionnaire validé a été administré aux participants à l'étude. Les participants ont subi des analyses de sang pour les paramètres de la formule sanguine complète (CBC) et une analyse du profil en fer. L'étude a révélé que 52,5 % des étudiantes souffraient d'anémie et de faibles taux de fer sérique. En ce qui concerne les résultats scolaires, des corrélations positives significatives ont été trouvées entre divers paramètres de CBC, notamment le nombre de globules blancs, l'hémoglobine, l'hématocrite, le volume cellulaire moyen, l'hémoglobine cellulaire moyenne, la concentration moyenne d'hémoglobine cellulaire et le fer sérique. Cependant, aucune corrélation significative n'a été observée entre le nombre de globules rouges et le nombre de plaquettes avec les résultats scolaires. Les variables démographiques étaient également associées à un rapport de cotes plus élevé d'anémie. L'étude met en évidence la prévalence de l'anémie chez les étudiantes et son impact potentiel sur la réussite scolaire. L'étude actuelle souligne l'importance de lutter contre l'anémie chez les jeunes femmes adultes et de mettre en œuvre des interventions appropriées pour améliorer leurs résultats scolaires.

RESUMEN

BACKGROUND: The physiological requirements for iron and folic acid in pregnancy are a significant challenge to achieve through normal dietary intake, especially in low resource settings. The World Health Organization recommends daily oral iron and folic acid supplementation (IFAS) to prevent maternal anaemia and related adverse effects in community settings where the prevalence of anaemia during pregnancy is > 40%. The objective of this study was to assess the routine uptake of prenatal iron-folic acid supplementation and associated factors among pregnant women at peri-urban areas of Dodoma City, Tanzania. METHODS: A cross-sectional study was conducted in peri-urban areas. Data was collected through face-to-face interviews and review of records from maternal clinic card (RCH 4 card). Routine uptake of iron-folic acid supplementation was defined as pregnant woman who reported taking iron-folic acid supplements at least once within the past seven days prior to data collection. Frequency and percentage were used to report respondents' characteristics and uptake of prenatal iron-folic acid supplementation. Chi-square test and logistic regression were conducted to determine the relationship and association of routine uptake of iron-folic acid supplementation with respondents' characteristics. RESULTS: The total respondents were 452. Overall routine uptake of iron-folic acid supplementation was 35.6% (161). The majority of the respondents (66.5%) initiated iron-folic acid supplementation during the second trimester of pregnancy. Most of the respondents (86.3%) obtained IFA supplements at the health centers where they were receiving antenatal care. The prevalence of routine uptake of iron-folic acid supplementation was significantly higher among women in the third trimester of pregnancy (54.9%), those with more than a five-year interval since last pregnancy (40.6%), those with at least four antenatal care (ANC) visits (73.7%) and women who had undergone haemoglobin testing in the current pregnancy (63.0%). Factors associated with routine uptake of iron-folic acid supplementation were; frequency of ANC visits (AOR = 1.69) and haemoglobin testing (AOR = 3.02). CONCLUSION: Approximately one third of the pregnant women took iron-folic acid supplementation at least once a week. The current frequency for intake of iron-folic acid supplementation can be described as intermittent. This practise is unacceptable for prevention of maternal anaemia and associated adverse pregnant outcomes. Frequency of ANC visits and haemoglobin testing during pregnancy were found to be associated with routine uptake of iron-folic acid supplements. Stakeholders are urged to consider novel systems for provision of prenatal IFAS in community settings with limited access to health-care professionals to ensure a timely and continuous supply of supplements.

RESUMEN

Iron deficiency anemia (IDA) is prevalent in exclusively breastfed (EBF) Thai infants. However, in Thailand, iron supplementation guidelines for EBF infants are not available. This prospective open-label study aimed to estimate the prevalence of IDA in 9-month-old EBF infants after receiving iron supplementation from 4 months of age until they consumed adequate iron-rich food. Forty-seven healthy, 4-month-old EBF infants were prescribed 1 mg/kg/day ferrous sulfate. Their complementary food records from 6 to 9 months were calculated for daily iron intake. Complete blood count and iron study were performed at 9 months of age. The results showed that the prevalence of IDA at 9 months was 6.4%. An employed caregiver and the male sex of the baby were significantly associated with iron deficiency. The food record revealed that the median daily iron intake was less than the Thai dietary reference intake recommendation. In summary, the prevalence of IDA in infants with 9 months of exclusive breastfeeding who received iron supplementation was lower than the background rate (25.7%) when iron was not prescribed. Most infants did not have adequate iron in complementary foods. Iron supplementation should be prescribed routinely during 4-9 months of age in healthy Thai EBF infants.

RESUMEN

AIM: Comparative analysis of clinical, anamnestic, and laboratory and instrumental data of patients with chronic heart failure (CHF) and iron deficiency (ID) diagnosed according to the AHA/ESC/RSC criteria, and CHF patients diagnosed with ID based on decreased transferrin saturation (TSAT) ≤19.8% or serum iron (Fe) ≤13 µmol/l. MATERIAL AND METHODS: An additional analysis of the ID-CHF-RF study was performed. The analyzed population included 498 patients (198 women) with CHF. In addition to the ID criteria provided by the protocol (AHA/ESC/RSC criteria: ferritin <100 µg/l or ferritin from 100 to 299 µg/l and TSAT<20%), concentrations of ID biomarkers were assessed, which showed high sensitivity and specificity for the diagnosis of ID compared to the morphological picture of the bone marrow (TSAT<19.8% or Fe ≤13 µmol/l). Subgroups of patients with ID determined only by the AHA/ESC/RSC criteria, only by the TSAT≤19.8% and Fe ≤13 µmol/l criteria, and by both were analyzed. RESULTS: ID diagnosed by the AHA/ESC/RSC criteria was found in 83.1% of patients. The TSAT ≤19.8% and Fe ≤13 µmol/l criteria revealed ID in 74.5% of patients. In 341 patients (76.8%), ID was diagnosed using both criteria. Patients with ID diagnosed by the TSAT≤19.8% and Fe≤13 µmol/l criteria, compared with patients with ID diagnosed by the AHA/ESC/RKO criteria, had a 50% lower Fe (9.8 µmol/l vs. 19.4 µmol/l) and a higher incidence of anemia (43.3% vs. 23.3%) and diabetes mellitus (DM) (36.7% and 24.7%). Also, these patients had higher values of body mass index (BMI) and NT-proBNP concentration (2317 [1305;9092] vs. 1691 [709;3856] pg/ml), and lower LV EF values (41.5 [29.0;54.5]% vs. 45.0 [34.0;54.0]%), respectively. The most severe course of CHF and the greatest changes in laboratory tests associated with ID and anemia were observed in patients with ID determined by two criteria. Patients in this group were older, with a higher BMI, more frequent presence of atrial fibrillation, and higher NT-proBNP (4182 [1854;9341] pg/ml). CONCLUSION: Patients with isolated low ferritin are characterized by less severe clinical and functional impairment compared to patients with low TSAT or Fe. At the same time, patients with ferritin higher than 300 µg/l and low TSAT and/or Fe were characterized by very severe CHF and a low functional status, although this may not be related with ID. Thus, the use of the ferritin-based criteria of ID may lead to overdiagnosis of ID in some patients and, at the same time, miss some of the most "severe" patients who likely require the ID correction. Patients with ID who show a decrease in all three parameters are likely to benefit most from Fe supplementation. It is advisable to perform additional studies on the effect of Fe supplements on the course and prognosis of the disease in this cohort of patients.

RESUMEN

BACKGROUND: The present study is a type of exploratory qualitative studies and applied research. The approach of this study is a prospective policy analysis in which we will formulate appropriate policy options to prevent and control iron deficiency anemia in Iran. METHODS AND MATERIALS: Current study is a multi-method research with an analysis for policy approach containing three phases. First, through a literature review study, policies, programs and interventions of different countries to control and prevent anemia caused by iron deficiency will be identified. Then, in the qualitative phase of the study, the challenges, barriers, facilitators of the policies and programs implemented and ongoing in Iran will be examined. The content and policy-making process, as well as the context and role of stakeholders and actors will be analyzed using the framework of the policy triangle and analysis of the policy process using the Kingdon's multiple streams model. Then, the proposed initial policy options will be developed. In the next phase, an expert panel contain experts, authorities and policymakers will be formed and the proposed options will be reviewed and categorized. In order to prioritize policy options and evaluate their feasibility in Iran, the Delphi technique and the policy options analysis framework of the Centers for Disease Control and Prevention (CDC) will be used. At the end, policy options will be selected based on the highest score and will be presented as appropriate policy options. CONCLUSION: Prospective policy analysis allows the selection of potentially practical and effective policy options to control iron deficiency anemia. The findings of current study will be presented as reports and research articles for policy makers.

RESUMEN

Anemia is highly prevalent globally, especially in young children in low-income countries, where it often overlaps with a high burden of diarrheal disease. Distribution of iron interventions (as supplements or iron-containing multiple micronutrient powders, MNPs) is a key anemia reduction strategy. Small studies in Africa indicate iron may reprofile the gut microbiome towards pathogenic species. We seek to evaluate the safety of iron and MNPs based on their effects on diversity, composition, and function of the gut microbiome in children in rural Bangladesh as part of a large placebo-controlled randomized controlled trial of iron or MNPs given for 3 months (ACTRN12617000660381). In 923 infants, we evaluate the microbiome before, immediately following, and nine months after interventions, using 16S rRNA gene sequencing and shotgun metagenomics in a subset. We identify no increase in diarrhea with either treatment. In our primary analysis, neither iron nor MNPs alter gut microbiome diversity or composition. However, when not adjusting for multiple comparisons, compared to placebo, children receiving iron and MNPs exhibit reductions in commensal species (e.g., Bifidobacterium, Lactobacillus) and increases in potential pathogens, including Clostridium. These increases are most evident in children with baseline iron repletion and are further supported by trend-based statistical analyses.

RESUMEN

BACKGROUND: Despite routine iron supplementation for pregnant women in South Africa, anaemia and iron deficiency (ID) in pregnancy remain a public health concern. OBJECTIVE: To determine the associations between iron status and birth outcomes of pregnant women attending antenatal clinic at a regional hospital in Bloemfontein. METHODS: In this cross-sectional study of 427 pregnant women, blood was taken to analyze biomarkers of anaemia (haemoglobin), iron status (ferritin and soluble transferrin receptor) and inflammation (C-reactive protein and α-1-acid glycoprotein). A questionnaire was used to collect information about birth outcomes (birth weight and gestational age at birth), HIV exposure, sociodemographics, iron supplement intake, and maternal dietary iron intake using a validated quantified food frequency questionnaire. RESULTS: The median (Q1, Q3) weeks of gestation of participants was 32 (26, 36) at enrolment. Anaemia, iron deficiency (ID), ID anaemia (IDA) and ID erythropoiesis (IDE) were present in 42%, 31%, 19% and 9.8% of participants, respectively. Median (Q1, Q3) dietary and supplemental iron intake during pregnancy was 16.8 (12.7, 20.5) mg/d and 65 (65, 65) mg/d, respectively. The median (max-min) total iron intake (diet and supplements) was 81 (8.8-101.8) mg/d, with 88% of participants having a daily intake above the tolerable upper intake level of 45 mg/d. No significant associations of anaemia and iron status with low birth weight and prematurity were observed. However, infants born to participants in the third hemoglobin (Hb) quartile (Hb > 11.3-12.2 g/dL) had a shorter gestation by 1 week than those in the fourth Hb quartile (Hb > 12.2 g/dL) (p = 0.009). Compared to pregnant women without HIV, women with HIV had increased odds of being anaemic (OR:2.14, 95%CI: 1.41, 3.247), having ID (OR:2.19, 95%CI: 1.42, 3.37), IDA (OR:2.23, 95%CI: 1.36, 3.67), IDE (OR:2.22, 95%CI: 1.16, 4.22) and delivering prematurely (OR:2.39, 95%CI: 1.01, 5.64). CONCLUSION: In conclusion, anaemia, ID, and IDA were prevalent in this sample of pregnant women, despite the reported intake of prescribed iron supplements, with HIV-infected participants more likely to be iron deficient and anaemic. Research focusing on the best formulation and dosage of iron supplementation to enhance iron absorption and status, and compliance to supplementation is recommended, especially for those living with HIV infection.

RESUMEN

SummaryChildhood proptosis is an emergency with prevalence of 1.2% in hospital admissions. It has a wide spectrum of aetiologies ranging from infective and inflammatory to neoplastic. Iron deficiency anaemia (IDA)-induced extramedullary haematopoesis (EMH) is known to cause hepatosplenomegaly but proptosis is very rare. We describe a girl in middle childhood with subacute bilateral proptosis because of orbital EMH, secondary to chronic nutritional IDA. There was no hepatosplenomegaly. Haemogram depicted severe microcytic hypochromic anaemia with wide red cell distribution width. Red blood cell indices were suggestive of IDA, but serum ferritin was elevated. Bone marrow examination showed absent iron and MRI brain was suggestive of EMH tissue in the orbits. Red blood cell transfusion was given before attempting a biopsy after which the proptosis dramatically reduced and disappeared. IDA is a common entity that rarely can cause EMH at sites other than liver and spleen.

RESUMEN

BACKGROUND/OBJECTIVES: Iron (Fe) is a co-factor for enzymes of the developing brain necessitating sufficient supply. We investigated the effects of administering ferric derisomaltose/Fe isomaltoside (FDI) subcutaneously to Fe-deficient (ID) pregnant rats on cerebral and hepatic concentrations of essential metals and the expression of iron-relevant genes. METHODS: Pregnant rats subjected to ID were injected with FDI on the day of mating (E0), 14 days into pregnancy (E14), or the day of birth (postnatal (P0)). The efficacy was evaluated by determination of cerebral and hepatic Fe, copper (Cu), and zinc (Zn) and gene expression of ferroportin, hepcidin, and ferritin H + L in pups on P0 and as adults on P70. RESULTS: Females fed an ID diet (5.2 mg/kg Fe) had offspring with significantly lower cerebral and hepatic Fe compared to female controls fed a standard diet (158 mg/kg Fe). Cerebral Cu increased irrespective of supplying a standard diet or administering FDI combined with the standard diet. Hepatic hepcidin mRNA was significantly lower following ID. Cerebral hepcidin mRNA was hardly detectable irrespective of iron status. CONCLUSIONS: In conclusion, administering FDI subcutaneously to ID pregnant rats on E0 normalizes fetal cerebral and hepatic Fe. When applied at later gestational ages, supplementation with additional Fe to the offspring is needed to normalize cerebral and hepatic Fe.

RESUMEN

Iron is an essential nutrient in living organisms with multiple vital functions. Iron deficiency (ID) can cause long term health consequences beyond iron deficiency anemia (IDA). The high prevalence of ID and its long-term effects in patients with obesity and after metabolic and bariatric surgery (MBS) is recognized. Nevertheless, there is limited knowledge of the optimal route or dose for treatment of patients with obesity and post-MBS, and an evidence-based universal guideline for prevention and treatment of ID in short- and long-term post-MBS (PMBS) is not yet available. ID in the general population is currently treated with oral or parenteral iron, where oral iron treatment is considered the preferred option with parenteral iron as a second-line treatment in case there is intolerance or lack of response to oral iron. In patients with obesity with chronic low-grade inflammation and PMBS patients with altered gut anatomy and function, there are also alterations in the bioavailability and higher risks of side effects of available oral irons. The conclusions of current studies exploring effective treatment of iron deficiency in this population have been inconsistent and further well-planned randomized and prospective studies are needed. This is a narrative review of the literature on the available treatment options and strategies for treatment of ID in PMBS patients to recognize the knowledge gaps and provides topics of future research.

RESUMEN

OBJECTIVE: To evaluate and compare the blood transfusion requirements during delivery in third-trimester pregnant women with iron deficiency anaemia (IDA) who were treated with intravenous (IV) ferric carboxymaltose (FCM) versus those treated with oral iron supplementation. STUDY DESIGN: Comparative study. Place and Duration of the Study: Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkiye, from January 2017 to December 2022. METHODOLOGY: Pregnant women with haemoglobin (Hb) levels <10 g/dL in their third trimester were included. One group (n = 50) received IV FCM, while the other group (n = 96) received oral iron therapy. Key outcome measures included Hb levels at delivery and the need for a postpartum blood transfusion. Inclusion criteria were third-trimester pregnancy with IDA, and exclusion criteria included haematological or chronic systemic diseases and high-risk pregnancies. RESULTS: The mean initial Hb levels in the third trimester of pregnancy in the FCM group and oral iron group were 8.31 ± 0.96 g/dL and 9.29 ± 1.20 g/dL, respectively (p <0.001). The mean Hb levels in the delivery room were 11.09 ± 1.38 and 9.44 ± 1.16 g/dL, respectively (p <0.001). The rates of postpartum erythrocyte transfusion requirement were 6% (n = 3) and 18.75% (n = 18), respectively (p = 0.037). CONCLUSION: IV FCM administration to pregnant patients with IDA during the third trimester was found to be more effective than oral iron treatment in reducing blood transfusion rates.

RESUMEN

BACKGROUND Pseudomelanosis duodeni (PD) is a rare incidental endoscopic finding characterized by flat, discrete speckles of dark pigment, usually in the proximal duodenum. PD is associated with chronic conditions, including end-stage renal disease, hypertension, and diabetes, and with certain medications, including oral iron supplements and sulfur-containing antihypertensives. CASE REPORT A 56-year-old woman presented with lower abdominal pain, intermittent rectorragia, and a history of peptic ulcer disease and iron-deficiency anemia, treated with oral iron supplements. She was hemodynamically stable, and laboratory test results were pertinent only for microcytic anemia. In the workup of iron-deficiency anemia, esophagogastroduodenoscopy was performed, showing findings suspicious for PD, which was confirmed by pathology. Colonoscopy revealed large internal hemorrhoids, and hemorroidectomy was scheduled during the same admission. Duodenum biopsies showed edematous villosities and large clusters of pigmented macrophages, with golden-brown cytoplasm positively stained with Perl's Prussian blue stain, indicating the presence of iron inside the macrophages. These findings confirmed the PD diagnosis. The pigment in PD is composed primarily of iron and sulfur, with iron being the main component, as seen in staining. In our case, we present findings of PD along with lower gastrointestinal bleeding manifesting as hemmoroidal bleeding. Giving the anatomical nature of hemorrhoids and that our patient was on oral iron therapy, the most likely mechanism behind the development of PD in our case was related to the oral iron therapy. CONCLUSIONS PD is a benign disorder of the duodenum. Further studies are needed to investigate its long-term outcomes and to formulate optimal management strategies.

RESUMEN

Iron deficiency (ID) and restlessness are associated with sleep/wake-disorders (e.g., restless legs syndrome (RLS)) and neurodevelopmental disorders (attention deficit/hyperactivity and autism spectrum disorders (ADHD; ASD)). However, a standardized approach to assessing ID and restlessness is missing. We reviewed iron status and family sleep/ID history data collected at a sleep/wake behavior clinic under a quality improvement/quality assurance project. Restlessness was explored through patient and parental narratives and a 'suggested clinical immobilization test'. Of 199 patients, 94% had ID, with 43% having a family history of ID. ADHD (46%) and ASD (45%) were common conditions, along with chronic insomnia (61%), sleep-disordered breathing (50%), and parasomnias (22%). In unadjusted analysis, a family history of ID increased the odds (95% CI) of familial RLS (OR: 5.98, p = 0.0002, [2.35-15.2]), insomnia/DIMS (OR: 3.44, p = 0.0084, [1.37-8.64]), and RLS (OR: 7.00, p = 0.01, [1.49-32.93]) in patients with ADHD, and of insomnia/DIMS (OR: 4.77, p = 0.0014, [1.82-12.5]), RLS/PLMS (OR: 5.83, p = 0.009, [1.54-22.1]), RLS (OR: 4.05, p = 0.01, [1.33-12.3]), and familial RLS (OR: 2.82, p = 0.02, [1.17-6.81]) in patients with ASD. ID and restlessness were characteristics of ADHD and ASD, and a family history of ID increased the risk of sleep/wake-disorders. These findings highlight the need to integrate comprehensive blood work and family history to capture ID in children and adolescents with restless behaviors.

RESUMEN

Iron deficiency (ID) is common during gestation and in early infancy and has been shown to adversely affect cardiac development and function, which could lead to lasting cardiovascular consequences. Ketone supplementation has been shown to confer cardioprotective effects in numerous disease models. Here, we tested the hypothesis that maternal ketone supplementation during gestation would mitigate cardiac dysfunction in ID neonates. Female Sprague-Dawley rats were fed an iron-restricted or iron-replete diet before and throughout pregnancy. Throughout gestation, iron-restricted dams were given either a daily subcutaneous injection of ketone solution (containing ß-hydroxybutyrate [ßOHB]) or saline (vehicle). Neonatal offspring cardiac function was assessed by echocardiography at postnatal days (PD)3 and 13. Hearts and livers were collected post-mortem for assessments of mitochondrial function and gene expression profiles of markers oxidative stress and inflammation. Maternal iron restriction caused neonatal anemia and asymmetric growth restriction at all time points assessed, and maternal ßOHB treatment had no effect on these outcomes. Echocardiography revealed reduced ejection fraction despite enlarged hearts (relative to body weight) in ID offspring, resulting in impaired oxygen delivery, which was attenuated by maternal ßOHB supplementation. Further, maternal ketone supplementation affected biochemical markers of mitochondrial function, oxidative stress and inflammation in hearts of neonates, implicating these pathways in the protective effects conferred by ßOHB. In summary, ßOHB supplementation confers protection against cardiac dysfunction in ID neonates and could have implications for the treatment of anemic babies.

RESUMEN

Iron deficiency in pregnancy is related to many poor health outcomes, including anemia and low birth weight. A small number of previous studies have identified maternal body mass index (BMI) as a potential risk factor for poor iron status. Our objective was to examine the association between pre-pregnancy BMI, iron status, and anemia in a nationally representative sample of US adult women. We used data from the National Health and Nutrition Examination Survey (NHANES; 1999-2010) for pregnant women ages 18-49 years (n = 1156). BMI (kg/m2) was calculated using pre-pregnancy weight (self-reported) and height (measured at examination). Iron deficiency (ID) was defined as total body iron (calculated from serum ferritin and transferrin receptor using Cook's equation) < 0 mg/kg and anemia as hemoglobin < 11 g/dL. Associations were examined using weighted linear and Poisson regression models, adjusted for confounders (age, race/ethnicity, education, and trimester). Approximately 14% of pregnant women had ID and 8% had anemia in this sample. Ferritin and total body iron trended slightly lower (p = 0.12, p = 0.14) in women with pre-pregnancy BMI in the normal and overweight categories compared to the underweight and obese categories; hemoglobin concentrations were similar across BMI groups (p = 0.76). There were no differences in the prevalence of ID or anemia in women with pre-pregnancy overweight and obesity (ID: overweight, adjusted prevalence ratio (PR) = 1.27, 95%CI: 0.89-1.82; obesity, PR = 0.75, 95%CI: 0.39-1.45; anemia: overweight, PR = 1.08, 95%CI: 0.53-2.19; obesity, PR = 0.99, 95%CI: 0.49-2.01) compared to women with a normal BMI. Findings from these US nationally representative data indicate that total body iron, serum hemoglobin, ID, and anemia in pregnancy do not differ by pre-pregnancy BMI. Since ID and anemia during pregnancy remain significant public health concerns, NHANES should consider measuring current iron status in upcoming cycles.

RESUMEN

Elemental iron powders are used as food fortificants to reduce the incidence of iron deficiency anemia. However, many commercially available iron powders are relatively untested in vivo. The purpose of this study was to determine the hemoglobin regeneration efficiency (HRE) and relative iron bioavailability (RBV) of an electrolytic elemental iron powder (EIP), by treating anemic rats with 14 d iron repletion diets fortified with four different concentrations (12, 24, 36, or 48 mg iron/kg diet) of EIP and bakery-grade ferrous sulfate monohydrate (FS; FeSO4•H2O), or no added iron (control); n = 9-12/group. The HRE of FS was significantly higher (p ≤ 0.05) than EIP at each concentration of dietary iron tested. For EIP, the HREs (ratios) of diets containing 12, 24, 36, and 48 mg iron/kg were 0.356, 0.205, 0.197, and 0.163, respectively. For both EIP and FS, HRE was inversely associated with increasing dietary iron. The RBVs (%) of iron from EIP in diets at 12, 24, 36, and 48 mg iron/kg as compared to FS were 64.5, 59.1, 50.6, and 54.3%, respectively. Overall, findings show that at the concentrations of iron tested, EIP has RBVs greater than 50% and is an effective fortification agent to replenish hemoglobin and correct iron deficiency anemia.

RESUMEN

In Bangladesh, groundwater, the principal source of drinking water, contains predominantly high levels of iron. Drinking groundwater is associated with good iron status in populations. Against this backdrop, iron supplementation is often associated with side effects, which reduces its intake compliance. However, the level of iron in groundwater is not consistent, and low levels exist in many areas of the country. In the present study, we examined the role of groundwater with a low concentration of iron in the prevention of anemia in Bangladeshi children. In 2018, a cross-sectional study was conducted in Bangladesh among children aged 2-5 years (n = 122) who drank groundwater containing a low level of iron (0-<2 mg/L). The combined intake of iron was calculated from the key sources-diet, groundwater, and the simulated intake of MNPs. The intakes of iron were compared against the standard reference intake. The children's hemoglobin levels were measured using a photometer. The combined intake of iron from diet, groundwater with low levels of iron, and the simulated consumption of low-iron MNP in children was 5.8 ± 2.0 and 6.9 ± 2.5 mg/day, comprising 193% and 169% of the Estimated Average Requirements in the 2-3-year-old and 4-5-year-old subgroups, respectively. The combined intake of bioavailable iron from dietary and low-iron groundwater was 0.42 ± 0.023 and 0.22 ± 0.019 mg/day in children exposed to groundwater concentrations of 0.8-<2.0 mg/L and 0.0-<0.8 mg/L, respectively (p < 0.001). The mean concentration of hemoglobin in the respective groups was 12.17 ± 0.94 g/dL and 11.91 ± 0.91 g/dL (p = 0.30). The combined intake of iron from diet and the low-iron groundwater was associated with maintenance of hemoglobin concentration at the non-anemic level in > 90% of the children. The findings highlight the protective influence of the low concentration of iron in the drinking groundwater against childhood anemia in Bangladesh.
