Clay ingestion induced hypokalemic paralysis: a rare case report in an elderly female with severe iron deficiency anemia

Hypokalemic paralysis is a rare neuromuscular disorder characterized by painless muscle weakness resulting from low potassium levels, most commonly presenting during adolescence. In this case report, we detail the presentation and management of an 80-year-old female who experienced sudden onset bilateral limb weakness. Initial clinical assessment revealed the absence of reflexes and hypotonia in all four limbs without any gastrointestinal or neurological symptoms. Comprehensive diagnostic evaluation identified severe iron deficiency anemia and an unusual history of clay ingestion due to pica as the underlying causes of her hypokalemic paralysis. Treatment included intravenous and oral potassium supplementation, as well as packed cell volume transfusions, leading to a significant improvement in her symptoms and normalization of her potassium levels. This case highlights the need to consider atypical etiologies, such as pica-induced clay ingestion, in the differential diagnosis of hypokalemic paralysis, particularly in elderly patients with nutritional deficiencies. Early recognition and appropriate management are critical for favourable outcomes.

Safety and efficacy of ferric carboxymaltose in management of iron deficiency anemia in pregnant and peripartum women

Background: Anemia during pregnancy, often attributed to iron deficiency, poses substantial risks to both maternal and fetal health. This retrospective study aims to evaluate the safety and efficacy of intravenous ferric carboxymaltose (FCM) in managing anemia among pregnant women.Methods: The study encompasses women who received FCM treatment for anemia during pregnancy between October 2023 and March 2024 at SSG hospital, Vadodara. Key outcomes evaluated include maternal safety and pregnancy outcomes. Prospective observational study; Treatment effectiveness was assessed by repeat hemoglobin (Hb) measurements and patient report of well-being in the postpartum period. Safety was assessed by analysis of adverse drug reactions and fetal heart rate monitoring during the infusion.Results: A total of 50 patients were included. The intravenous administration of FCM notably raised hemoglobin levels in all pregnant female participants compared to initial levels. Monitoring of fetal heart rate showed no adverse effects attributable to the medication. No severe side effects were observed.Conclusions: This prospective observational study suggests that FCM represents a safe and effective therapeutic option for managing anemia during pregnancy. Despite study limitations, the findings underscore the potential of FCM in addressing this prevalent concern, advocating for its consideration in clinical practice.

Resumen Objetivo: El objetivo del presente estudio es evaluar en nuestro medio la prevalencia de anemia en el preoperatorio de la cirugía cardiovascular, su incidencia postoperatoria y su evolución durante el primer mes. Métodos: Se realizó un estudio de cohorte prospectivo en el que se incluyeron todos los pacientes sometidos a cirugía cardiovascular central intervenidos durante el periodo del 01/09/2021 al 01/09/2022 en un hospital universitario. Se realizó seguimiento clínico y de laboratorio previo a la cirugía, al quinto y al día treinta del postoperatorio. Se comparó a los grupos con y sin anemia preoperatoria. Resultados: La prevalencia de anemia en el preoperatorio fue del 32.1%. La incidencia de anemia en el postoperatorio fue del 96% en el grupo de pacientes sin anemia previa. Al mes de la cirugía un 73 y un 90% de los pacientes, con y sin anemia preoperatoria respectivamente, persistían anémicos. Los pacientes con anemia preoperatoria tuvieron una menor recuperación de sus valores de hemoglobina al mes. Se observó una tendencia a mayor mortalidad y una mayor necesidad de derivación a centros de rehabilitación postegreso hospitalario en aquellos con anemia preoperatoria. Conclusiones: En este trabajo se evidenció una alta prevalencia e incidencia de anemia en el perioperatorio de las cirugías cardiovasculares. Así como su subtratamiento y elevada persistencia durante el mes posterior a la cirugía.

Abstract Objective: The aim of this study is to evaluate the prevalence of anemia in the preoperative period of cardiovascular surgery, its postoperative incidence and its evolution during the first month in our setting. Methods: A prospective cohort study was carried out in which all patients undergoing central cardiovascular surgery operated during the period 09/01/2021-09/01/2022 in a university hospital were included. Clinical and laboratory follow-up was carried out prior to surgery, on the fifth and on the 30th postoperative day. Groups with and without preoperative anemia were compared. Results: The prevalence of anemia in the preoperative period was 32.1%. The incidence of anemia in the postoperative period was 96% in the group of patients without previous anemia. One month after surgery, 73 and 90% of the patients, with and without preoperative anemia, respectively, remained anemic. Patients with preoperative anemia had less recovery of their hemoglobin values at one month. A trend towards higher mortality and a greater need for referral to post-hospital discharge rehabilitation centers was observed in those with preoperative anemia. Conclusions: In this work, a high prevalence and incidence of anemia in the perioperative period of cardiovascular surgeries was evidenced. As well as its subtreatment and high persistence during the month after surgery.

Factores asociados a anemia ferropénica en lactantes y preescolares / Factors associated with iron deficiency anemia in infants and preschoolers

Introducción: La anemia se define como una afección en la cual el número de glóbulos rojos o la concentración de hemoglobina dentro de estos se encuentran por debajo del límite inferior, 11 gr/dl para menores entre 6 a 59 meses. La OMS calcula que a nivel mundial la anemia presenta una prevalencia del 42% en los niños menores de 5 años. Objetivos: Realizar una revisión panorámica de diversas publicaciones científicas acerca de los factores asociados a la anemia ferropénica en preescolares. Materiales y métodos: La revisión se realizó a través de la búsqueda electrónica de diversos artículos científicos relacionados con el tema. Se utilizó la pregunta PEO: ¿Cuáles son los factores asociados a anemia ferropénica en lactantes y preescolares? Se seleccionaron los artículos publicados desde el 2017 hasta el 2022. Resultados: De los 48 artículos encontrados en la revisión, 33 fueron descartados por no cumplir con nuestros criterios de selección, quedando 15 artículos para esta revisión. Basado en 12 artículos revisados, se halló que los factores que se asocian a anemia en menores de 5 años eran por problemas socioeconómicos, déficit de micronutrientes altos en hierro en dieta, madre con antecedente de anemia, la edad materna, falta de educación, entre otros. Conclusión: Los factores predisponentes para la presencia de anemia ferropénica en los menores de 5 años más importantes fueron los relacionados con la edad materna, el nivel socioeconómico y educativo de la madre que conllevan el déficit de hierro del menor.

Introduction: Anemia is defined as a condition in which the number of red blood cells or the hemoglobin concentration within red blood cells is below the lower limit, 11 g/dL for children aged 6-59 months. The WHO estimates that worldwide anemia has a prevalence of 42% in children under 5 years of age. Objectives: To perform an overview review of various scientific publications on the factors associated with iron deficiency anemia in preschoolers. Materials and methods: The review was carried out through an electronic search of various scientific articles related to the subject. The PEO question was used: What are the factors associated with iron deficiency anemia in infants and preschoolers? Articles published from 2017 to 2022 were selected. Results: Of the 48 articles found in the review, 33 were discarded for not meeting our selection criteria, leaving 15 articles for this review. Based on 12 articles reviewed, it was found that the factors associated with anemia in children under 5 years of age were socioeconomic problems, deficiency of micronutrients high in iron in the diet, mothers with a history of anemia, maternal age, lack of education, among others. Conclusion: The most important predisposing factors for the presence of iron deficiency anemia in children under 5 years of age were those related to maternal age, socioeconomic and educational level of the mother that lead to iron deficiency in the child.

Hepcidin and inflammation associated with iron deficiency in childhood obesity - A systematic review

Abstract Objectives: This paper aims to review data on the association of obesity and iron deficiency in children and adolescents, exposing the possible involvement of hepcidin and interleukin-6 (IL-6), obesity's inflammation biomarkers. Data source: Articles from PUBMED and WEB OF SCIENCE database with no chronological limit were reviewed to write this systematic review. Keywords such as children, obesity, iron deficiency, and hepcidin were used. After deleting duplicated and review articles, 91 were screened, and 39 were selected as eligible. Sixteen articles were included because they involved serum hepcidin levels in obese children and adolescents as outcomes. Summary of findings: Finally, those 16 articles were organized in two tables: one includes therapeutic interventions, and the other does not. As hepcidin was discovered in 2000, the first articles that presented serum hepcidin's quantification in obese children and adolescents, homeostasis iron markers, and their possible association with obesity's inflammatory environment began to be published in 2008. Conclusions: Obesity's chronic inflammation state leads to the production of IL-6, which acts as a signaling molecule for hepcidin synthesis, resulting in iron deficiency, which is common in obese children and adolescents who respond inadequately to iron supplementation. On the other hand, that population responds adequately to therapeutic intervention programs that lead to weight loss, guaranteeing iron homeostasis improvement. Therefore, perhaps it is time to discuss serum hepcidin level quantification as part of evaluating children and adolescents with iron deficiency, which could guide clinical choices that might lead to better therapeutic outcomes.

Riesgos y beneficios de la profilaxis con sulfato ferroso en lactantes nacidos a término con niveles de hemoglobina y ferremia desconocidos / Risks and benefits of iron supplementation in full-term infants with unknown hemoglobin and ferritin levels

La seguridad y eficacia de los programas de suplementación con hierro a lactantes, está actualmente en discusión. El objetivo de esta revisión fue identificar estudios sobre riesgos y beneficios de la suplementación con hierro profiláctico en lactantes menores de un año, nacidos a término, con niveles de hemoglobina (Hb) y ferremia desconocidos. Se realizó una búsqueda en Pubmed y Cochrane, identificando 3 revisiones sistemáticas y metaanálisis. Estos estudios arrojaron resultados que indican mejoras en los niveles séricos de hierro y hemoglobina como resultado de la suplementación con hierro. Sin embargo, no se observó un beneficio significativo en el desarrollo cognitivo de los lactantes. Los efectos adversos más reportados son los gastrointestinales, efectos en el crecimiento (menor ganancia de talla y peso) y menor absorción de zinc. En resumen, la evidencia en cuanto a la profilaxis con hierro en lactantes es limitada, lo que nos lleva a recomendar un seguimiento cercano de los lactantes que reciben suplementos de hierro, con el objetivo de detectar posibles eventos adversos. Es fundamental evaluar cuidadosamente los riesgos y beneficios de esta intervención antes de su implementación (AU)

The safety and efficacy of iron supplementation programs for infants are currently under discussion. The objective of this review was to identify studies on the risks and benefits of prophylactic iron supplementation in infants under one year of age, born at term, with unknown hemoglobin (Hb) and serum iron levels. The search was conducted on Pubmed and Cochrane, identifying three systematic reviews and meta-analyses. The results indicate improvements in serum iron and hemoglobin levels as a result of iron supplementation. However, a significant benefit in infant cognitive development was not observed. The most reported adverse effects were gastrointestinal, effects on growth (reduced height and weight gain), and reduced zinc absorption. In summary, the evidence regarding iron prophylaxis in infants is limited, leading us to recommend close monitoring of infants receiving iron supplements to detect potential adverse events. It is crucial to carefully assess the risks and benefits of this intervention before implementation (AU)

Iron pill associated duodenitis: a less recognised clinical entity

Iron supplementation is a widely prescribed treatment for anemia, but its association with gastrointestinal complications, specifically duodenitis, remains inadequately acknowledged in clinical practice. One of the common oral iron preparations to treat iron deficiency anemia is ferrous sulphate. Iron preparations have been known to cause gastric side effects, including gastritis and duodenitis. This case report explores the emerging concern of iron pill-associated duodenitis, shedding light on the potential adverse effects of oral iron supplementation on the duodenal mucosa. Existing literature and clinical cases are reviewed to highlight the connection between iron pill consumption and duodenal inflammation. From asymptomatic cases to severe symptoms like abdominal pain and gastrointestinal bleeding, the clinical spectrum is diverse. Histopathological analysis of endoscopic biopsies reveals characteristic features of duodenitis linked with iron deposits, raising concerns about long-term consequences. In conclusion, this case underscores the significance of recognizing iron pill-associated duodenitis as a distinct clinical entity, necessitating further investigation for optimized patient care and the safe administration of iron supplements in managing anemia.

Association of iron deficiency anemia with acute bronchiolitis in children below 2 years of age

Background: Bronchiolitis is the leading cause of respiratory distress in small children and one of the main causes of hospitalization in children <2 years of age. Anemia is also identified as a risk factor for lower respiratory tract infection. Iron deficiency is considered the most common cause of anemia in developing countries. As anemia is highly prevalent in children of our country, this study was undertaken to evaluate whether iron deficiency anemia is associated with acute bronchiolitis.Method: This Cross-Sectional Analytical study was carried out in the Department of Paediatrics, Sir Salimullah Medical College Mitford Hospital (SSMCMH), Dhaka, during the period of December 2021 to November 2022 after obtaining ethical approval to explore the association between iron deficiency anemia and bronchiolitis. Hemoglobin level, RBC indices, TWBC count, serum iron, TIBC level, Transferrin saturation, and PBF were investigated and compared in all children with bronchiolitis and control. For this purpose, a total number of 71 patients were enrolled in the study and among them, 35 children with bronchiolitis were considered as cases, and 36 healthy children without bronchiolitis were considered as control, who were matched with age. After taking written informed consent from parents/legal guardians, a detailed history and thorough clinical examination and laboratory investigations were carried out on each child. Data were recorded in separate case record form and analyzed by SPSS version 23.0.Results: The mean age was found 12.1�7 months in cases and 14.1�9 months in controls. Male participants (47, 66.2%) were the predominant group in the study and female participants were (24, 33.8%). Exclusive breastfeeding was found in 10 (28.6%) cases and 25 (71.4%) controls. There was a statistically significant difference in Hb (gm/dl), MCV (fl), S.Iron (礸/dl), Transferrin Saturation (%) and RDW-CV (%) between cases and controls (p<0.05). Among 35 cases, 25 (67.6%) had Iron Deficiency Anemia and statistical difference between the case and control was significant (p=0.001) with an odds ratio of 5.0.Conclusion: Iron deficiency anemia has a significant association with bronchiolitis. A larger and more extensive study was recommended.

Research progress of Hp infection and blood system related diseases / 重庆医学

Helicobacter Pylori(Hp)is a spiral bacterium that colonized on the surface of gastric muco-sal epithelium.It is the main cause of gastrointestinal diseases because human is the only natural host and can survive in gastric acid.In recent years,relevant clinical studies have shown that Hp infection is closely related to hematological diseases such as allergic purpura(HSP),immune thrombocytopenic purpura(ITP),iron de-ficiency anemia(IDA),megaloblastic anemia(MA),lymphoma,leukemia and so on.Therefore,for Hp infec-tion,early diagnosis and treatment are of great significance for improving the efficacy of hematological diseases.

Study on the Distribution of Traditional Chinese Medicine Constitution in Pregnant Women with Iron Deficiency Anemia and Its Influencing Factors / 广州中医药大学学报

Objective To investigate the distribution of traditional Chinese medicine(TCM)constitution in pregnant women with iron deficiency anemia(IDA)and its related influencing factors,so as to provide a reference for the TCM prevention and treatment of IDA in pregnancy.Methods A total of 109 eligible patients with IDA during pregnancy were included in the study.The general data of pregnant women,the TCM constitution types and relevant laboratory indicators including serum ferritin(Fer),hemoglobin(Hb)and mean corpuscular volume(MCV)were collected.Statistical analyses were conducted on the distribution of TCM constitution types of IDA pregnant women and its related influencing factors as well as the pregnancy outcomes.Results(1)The 109 IDA pregnant women were predominated by biased constitution types,accounted for 60 cases(55.05％).The distribution of the constitution types of 109 IDA pregnant women was as follows:balanced constitution(49 cases,44.95％)>damp-heat constitution(13 cases,11.93％)>yang deficiency constitution(12 cases,11.01％)>yin deficiency constitution(11 cases,10.09％)>qi deficiency constitution(10 cases,9.17％)>qi stagnation constitution(9 cases,8.26％)>blood stasis constitution(3 cases,2.75％)>phlegm-damp constitution(2 cases,1.83％).(2)Comparison of Hb and MCV levels in IDA pregnant women with various constitution types showed no statistically significant differences(P>0.05),but Fer level in IDA pregnant women with damp-heat constitution was significantly higher than that in IDA pregnant women with balanced constitution(P<0.01),and the probability of occurrence of amniotic opacity in IDA pregnant women with damp-heat constitution was significantly higher than that in IDA pregnant women with balanced constitution and other biased constitution types(P<0.05).Conclusion Damp-heat constitution is the most common TCM constitution type in pregnant women with IDA,followed by yang deficiency constitution,yin deficiency constitution and qi deficiency constitution.The damp-heat constitution may be the susceptible constitution of pregnant women with IDA,and IDA pregnant women with damp-heat constitution have significantly higher Fer level than those with balanced constitution,and also have the higher probability of occurrence of amniotic opacity than those with balanced constitution and other biased constitution types.

Establishment of reference intervals for serum sTfR and sTfR/lgSF in apparently healthy adults in Wuhan / 中国输血杂志

【Objective】 To establish reference intervals for serum soluble transferrin receptor (sTfR) and sTfR/log serum ferritin index (sTfR/lgSF) in apparently healthy adults in the Wuhan area, so as to provide reference for clinical diagnosis and treatment of iron deficiency and iron-deficiency anemia. 【Methods】 A total of 273 individuals from the Wuhan Aisa General Hospital, including health examination participants and blood donors, were selected to measure sTfR, other iron metabolism indicators and high sensitivity C-reactive protein(hsCRP). The sTfR/lgSF values were calculated and reference intervals for sTfR and sTfR /lgSF were established using the percentile method (P2.5 to P97.5). Spearman correlation analysis was used to evaluate the relationships between sTfR, sTfR/lgSF, and other iron metabolism indicators, as well as hsCRP. 【Results】 The sTfR levels (M, mg/L) between males and females (1.01 vs 1.07) were not statistically significant (P>0.05), but the sTfR/lgSF levels if males were significantly lower than those in females (0.45 vs 0.62)(P0.05). The reference interval for STfR was (0.72-1.68) mg/L, the sTfR/lgSF reference interval was (0.31-0.88) for males, and (0.37-1.19) for females. Correlation analysis showed no correlation between sTfR, sTfR/lgSF and hsCRP (r=0.043, P>0.05; r=-0.064, P>0.05), while serum ferritin(SF), serum iron(SI), transferrin saturation(TSAT)were correlated with hsCRP (r=0.128, P0.05), while sTfR/lgSF was significantly correlated with and SF (r=-0.685, P<0.01). 【Conclusion】 Preliminary reference intervals for serum sTfR and sTfR/lgSF in apparently healthy adults in the Wuhan has been established. sTfR and sTfR/lgSF are not affected by inflammatory factors and are significant for identifying iron deficiency in anemia patients with elevated serum ferritin caused by inflammation.

Evaluation of rational use of intravenous iron in patients with iron deficient anemia and abnormal uterine bleeding in gynaecology / 中国药师

Objective To investigate the application of intravenous iron in patients with abnormal uterine bleeding(AUD)and iron deficiency anemia(IDA)in gynecology,to establish the drug utilization evaluation(DUE)standard,and to comprehensively evaluate the rationality of the clinical application of intravenous iron by analytic hierarchy process(AHP),so as to provide reference for the rational use of intravenous iron in clinical practice.Methods The medical records of patients with AUD and IDA from January to December 2022 in the First Affiliated Hospital of Anhui University of Science and Technology were collected,and the special rationality of the drug was evaluated from the aspects of indications,route and frequency of administration,daily dosage,solvent,combination medication,and contraindications of iron sucrose injection,and the DUE standard of the drug was formulated.AHP was used to analyze and evaluate 113 archived cases of intravenous iron in gynecology from January to December 2022.Results A total of 113 patients were treated with iron sucrose injection,and the indications,route of administration,solvent,contraindications,and allergic reactions were reasonable.The main unreasonableness was that the frequency of administration was inappropriate,the daily dose was inappropriate,the combination was not appropriate,the total iron supplement was not up to standard,and there was no continuous drug monitoring after medication.The case scores 90～100,70～<90 and 60～<70 were 6(5.31%),106(93.81%)and 1(0.88%),respectively.Conclusion Patients with AUD and IDA should pay attention to the dosage,total amount of iron supplementation,combined application of drugs and continuous medication monitoring after intravenous iron supplementation,so as to improve the rationality of their use.

Association entre l'anémie ferriprive et les convulsions fébriles chez les enfants âgés de 6 mois à 60 mois à Yaoundé / Iron Deficiency Anemia and Febrile Seizures in Children Aged 6 to 60 Months in Yaounde

Introduction.Les convulsions fébriles (CF) sont l'une des affections neurologiques les plus courantes de l'enfance. Plusieurs théories, telles que l'anémie ferriprive, ont été proposées comme pathogénie de cette affection. L'objectif de cette étude était de déterminer l'association entre l'anémie ferriprive et les convulsions fébriles chez les enfants âgés de 6 mois à 60 mois.Méthodologie. Il s'agissait d'une étude cas-témoins menée de Janvier à Mai 2021 chez 43 enfants ayant des CF (cas) et 43 enfants fébriles sans convulsions (témoins) admis dans deux hôpitauxà Yaoundé. Les deux groupes étaient appariés en fonction de l'âge et du sexe. Chez tous, le taux d'hémoglobine, le volume globulaire moyen(VGM), la teneur corpusculaire moyenne en hémoglobine (CCMH) et la ferritine plasmatique ont été déterminés.Résultats.L'âge moyen était de 23 mois. Les antécédents familiaux de convulsions fébriles(CF)étaient retrouvés dans 27,9 % des cas. Les CF simples étaient les plus fréquentes (69,8%) avec une prédominance des crises tonicocloniques généralisées (74,4%). Les infections ORL et le paludisme étaient les causes de la fièvre dans 72,1% des cas. Les enfants avec convulsions fébriles avaient trois fois plus de risque d'avoir une anémie comparée aux témoins (P), par contre les valeurs moyennes , TCMH n'étaient pas significativement différents dans les deux groupes. Les deux groupes présentaient une carence martiale mais sans différence significative. Conclusion.Les enfants avec CF présentaient plus d'anémie, mais la carence en fer bien que présente dans les deux groupes l'était sans différence significative

ntroduction.Febrile convulsions (FC) are one of the most common neurological disorders in childhood. Several theories, such as iron deficiency anemia, have been proposed as the pathogenesis of this condition. The aim of this study was to determine the association between iron deficiency anemia and febrile convulsions in children aged 6 to 60 months. Methodology.This was a case-control study conducted from January to May 2021 involving 43 children with FC (cases) and 43 febrile children without convulsions (controls) admitted to two hospitals in Yaoundé. The two groups were matched for age and sex. Hemoglobin levels, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), and plasma ferritin levels were determined in all participants. Results.The average age was 23 months. Family history of febrile convulsions (FC) was found in 27.9% of cases. Simple FC were the most common (69.8%) with a predominance of generalized tonic-clonic seizures (74.4%). ENT infections and malaria were the causes of fever in 72.1% of cases. Children with febrile convulsions were three times more likely to have anemia compared to controls (P= 0.028), however, the average values of MCV and MCHC were not significantly different in the two groups. Both groups had iron deficiency but without significant differences. Conclusion.Children with FC had more anemia, but iron deficiency

Association between preoperative anemia optimization and major complications after non-cardiac surgery: a retrospective analysis

Abstract Background: Anemia is common in the preoperative setting and associated with increased postoperative complications and mortality. However, it is unclear if preoperative anemia optimization reduces postoperative complications. We aimed to assess the association between preoperative anemia optimization and a composite endpoint of major cardiovascular, renal, and pulmonary complications and all-cause mortality within 30 days after noncardiac surgery in adult patients. Methods: In this retrospective analysis preoperative anemia was defined as hemoglobin concentration below 12.0 g.dl−1 in women and 13.0 g.dl−1 in men within 6 months before surgery. A propensity score-based generalized estimating equation analysis was used to determine the association between preoperative anemia optimization and the primary outcome. Moreover, mediation analysis was conducted to investigate whether intraoperative red blood cell transfusion or duration of intraoperative hypotension were mediators of the relation between anemia optimization and the primary outcome. Results: Fifty-seven hundred anemia optimized, and 8721 non-optimized patients met study criteria. The proportion of patients having any component of the composite of major complications and all-cause mortality was 21.5% in the anemia-optimized versus 18.0% in the non-optimized, with confounder-adjusted odds ratio estimate of 0.99 (95% CI 0.86-1.15) for anemia optimization versus non-optimization, p = 0.90. Intraoperative red blood cell transfusion had a minor mediation effect on the relationship between preoperative anemia optimization and the primary outcome, whereas duration of intraoperative hypotension was not found to be a mediator. Conclusion: Preoperative anemia optimization did not appear to be associated with a composite outcome of major in-hospital postoperative cardiovascular, renal, and pulmonary complications and all-cause in-hospital mortality.

Ambos grupos con incremento de 1 g/dL entre la hemoglobina inicial y final (p < 0.01), con una diferencia de medias entre el aumento de los grupos con p = 0.4. Con disminución significativa de la epigastralgia y la náusea. CONCLUSIONES: El tratamiento intermitente con sulfato ferroso incrementa las concentraciones de hemoglobina igual que un esquema continuo, pero con menos efectos adversos.

Abstract OBJECTIVE: To compare hemoglobin concentrations in pregnant women with iron deficiency anemia who received intermittent versus continuous treatment with 200 mg oral ferrous sulfate. In addition, to compare the incidence of side effects of intermittent versus continuous treatment. MATERIALS AND METHODS: Randomized, non-blinded, clinical trial conducted at the Unidad Médica de Alta Especialidad Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, IMSS, in patients aged 18 to 35 years attended between January and March 2023 with 30 or more weeks of pregnancy, diagnosis of iron deficiency anemia (operationally defined only with a blood biometry lower than 11 g/dL, with hypochromia and microcytosis), without a history of chronic degenerative disease. Statistical analysis was performed in SPSS v21 program, distribution and characteristics of the sample with univariate analysis, followed by bivariate analysis with Student's t and mean difference. A value of p < 0.05 was considered statistically significant. RESULTS: Thirty-two patients were studied: 16 with continuous and 16 with intermittent regimen. Both groups with increase of 1 g/dL between initial and final hemoglobin (p < 0.01), with a mean difference between groups increase with p = 0.4. With significant reduction in epigastralgia and nausea. CONCLUSIONS: Intermittent treatment with ferrous sulfate increases hemoglobin concentrations.

Iron deficiency anemia as a risk factor for pulp disease in children from the central Peruvian jungle: a case‒control study

Abstract Aim To investigate iron-deficiency anemia as a risk factor for dental pulp disease in children from the central Peruvian jungle. Methodology A case-control study was carried out with 270 children, of which 90 referred to cases and 180, to controls. Patients with pulp disease were diagnosed according to the criteria of the Association of Endodontists and the American Board of Endodontics. A specific questionnaire was used to assess ferrous sulfate consumption, maternal education level, maternal age, occupation, and household income. Data were analyzed using Pearson's correlation coefficient and a binary logistic regression. Results Iron deficiency anemia offers a risk factor for pulp disease in children (OR 7.44, IC 95% 4.0-13.8). According to multivariate analysis using binary logistic regression, ferrous sulfate consumption (OR 13.8, IC 95% 5.6.33.9), maternal education level (OR 2.4, IC 95% 1.1-5.3), maternal age (OR 7.5, IC 95% 2.9-19.4), household income (OR 4.0, IC 95% 1.6-9.6), and caries (OR 10.7, IC 95% 4.5-25.7) configured independent factors that were statistically associated with pulp disease. Conclusion Iron deficiency anemia, ferrous sulfate consumption, maternal education level, maternal age, household income, and dental caries were positively associated with pulp disease in children

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

Abstract 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.

Serum levels of phoenixin and nesfatin in patients with iron, vitamin B12 or vitamin D deficiency: a comparative study / Níveis séricos de fenixina e nesfatina em pacientes com deficiência de ferro, vitamina B12 ou vitamina D: um estudo comparativo

ABSTRACT Objective Micronutrient deficiencies are recognized as critical factors contributing to the global burden of disease. Phoenixin-14 and nesfatin-1 newly discovered neuropeptides which have been related to various physiological processes and potential therapeutic applications. This study was conducted to test whether circulating concentrations of nesfatin-1 and phoenixin-14 were altered in individuals with iron, vitamin B12, vitamin D and combined deficiencies. Method Our study group consists of 33 patients with iron deficiency, 30 patients with vitamin B12 deficiency, 33 patients with vitamin D deficiency, 32 patients with combined deficiency, 24 patients who received vitamin D supplementation and 32 control subjects. Serum nesfatin-1 and phoenixin-14 concentrations were determined measured by Enzyme-Linked ImmunoSorbent Assay method. Results Serum phoenixin-14 values were significantly lower in subjects with iron, vitamin B12, vitamin D and combined deficiency compared with the healthy group. After vitamin D supplementation, serum phoenixin-14 levels did not differ significantly with the healthy group. Serum nesfatin-1 concentrations were significantly lower in subjects with iron, vitamin B12 and combined deficiency compared with the healthy group. There was no significant difference in nesfatin-1 values between those with vitamin D deficiency, those taking vitamin D3 supplements and the healthy controls. Conclusion Significant differences in phoenixin-14 and nesfatin-1 levels between iron, vitamin D, vitamin B12 deficiency and the healthy control group supports that these molecules related to the pathogenesis of micronutrient deficiencies. Phoenixin-14 and nesfatin-1 may be considered potential biomarkers of micronutrient deficiencies.

A new effect of intravenous iron treatment in pregnancy: contraction in nonstress test and timing of labor

SUMMARY OBJECTIVE: The aim of this study was to elucidate the cause and results of contractions occurring in term pregnant women receiving intravenous iron therapy. METHODS: During 2019-2020, 136 pregnant women beyond 35 weeks of gestation, who received intravenous iron treatment due to iron deficiency anemia, were included through retrospective screening. Iron deficiency anemia was defined as having hemoglobin levels <10 g/dL and ferritin levels <15 ng/mL, and the pregnant women underwent nonstress test before and after treatment. RESULTS: The average treatment week for the pregnant women was 36.82±0.74, and the presence of regular contractions in post-treatment follow-up nonstress tests was 72.1% (n=98). The average week of birth was 38.48±1.60. Pregnant women with contractions who had previous cesarean were found to have a mean delivery week of 36.82±0.67, which was statistically significant earlier than for nulliparous and multiparous women (p<0.001). Conclusion: In pregnant women with iron deficiency anemia who were beyond 35 weeks, temporary regular contractions may be observed in the nonstress test following intravenous iron replacement. We think that this effect may lead to early term birth in pregnant women with a history of cesarean section. It needs to be confirmed by further prospective studies and animal studies.
