RÉSUMÉ

ABSTRACT Background: Iron overload is frequent in patients with chronic liver disease, associated with shorter survival after liver transplantation in patients with hereditary hemochromatosis. Its effect on patients without hereditary hemochromatosis is unclear. The aim of the study was to study the clinical impact of iron overload in patients who underwent liver transplantation at an academic tertiary referral center. Methods: We performed a retrospective cohort study including all patients without hereditary hemochromatosis who underwent liver transplantation from 2015 to 2017 at an academic tertiary referral center in Mexico City. Explant liver biopsies were reprocessed to obtain the histochemical hepatic iron index, considering a score ≥ 0.15 as iron overload. Baseline characteristics were compared between patients with and without iron overload. Survival was estimated using the Kaplan-Meier method, compared with the log-rank test and the Cox proportional hazards model. Results: Of 105 patients included, 45% had iron overload. Viral and metabolic etiologies, alcohol consumption, and obesity were more frequent in patients with iron overload than in those without iron overload (43% vs. 21%, 32% vs. 22%, p = 0.011; 34% vs. 9%, p = 0.001; and 32% vs. 12%, p = 0.013, respectively). Eight patients died within 90 days after liver transplantation (one with iron overload). Complication rate was higher in patients with iron overload versus those without iron overload (223 vs. 93 events/100 person-months; median time to any complication of 2 vs. 3 days, p = 0.043), without differences in complication type. Fatality rate was lower in patients with iron overload versus those without iron overload (0.7 vs. 4.5 deaths/100 person-months, p = 0.055). Conclusion: Detecting iron overload might identify patients at risk of early complications after liver transplantation. Further studies are required to understand the role of iron overload in survival.

Objetivo: la ferritina es importante en el almacenamiento de hierro intracelular, en una forma soluble no tóxica. Sus niveles en la gestación se la relacionan con la salud de la madre y con su descendencia. El objetivo es escribir los niveles séricos de ferritina y prevalencia de déficit de ferritina, así como los factores sociodemográficos asociados en gestantes de Colombia. Metodología: estudio transversal; análisis secundario de la Encuesta de Situación Nutricional de Colombia, 2015. Se evaluaron en 1.234 embarazadas con edades entre 12 y 48 años: sus características sociodemográficas y antropométricas, la distribución de los niveles séricos y la prevalencia de déficit de ferritina. Para estimar la asociación entre las diferentes variables sociodemográficas y los niveles séricos, o la prevalencia de déficit de ferritina, se utilizaron modelos de regresión multivariables. Resultados: la prevalencia de deficiencia de ferritina fue de 44.5 % (IC 95 % 40.1 % a 49.0 %), los niveles séricos de ferritina oscilaron entre 4 µg/L y 295,7 µg/L, con un promedio de 29.3 µg/L (IC 95 % 26,5 µg/L-32.2 µg/L). Las gestantes del segundo (OR (OR 2.19 IC 95 % 1.50 a 3.19) y tercer trimestre (OR 3.84 IC 95 % 2.68 a 5.50), aquellas que residen en la región Atlántica (OR 2.18 IC 95 % 1.25 a 3.82) y en la región Orinoquia (OR 2.41 IC 95 %1.19 a 4.88), mostraron asociación con el déficit de ferritina. Conclusión: se halló alta prevalencia en el déficit de ferritina en gestantes colombianas.


Introduction: Ferritin is important in the storage of intracellular iron, in a non-toxic soluble form. Its levels during pregnancy are related to the health of the mother and her offspring. Objective: To describe the serum ferritin levels and the prevalence of ferritin deficiency, and the associated sociodemographic factors in pregnant women in Colombia. Methodology: Cross-sectional study; secondary analysis of the Nutritional Situation Survey of Colombia, 2015. The following were evaluated in 1,234 pregnant women aged between 12 and 48 years: their sociodemographic and anthropometric characteristics, the distribution of serum levels, and the prevalence of ferritin deficiency. To estimate the association between the different sociodemographic variables and serum levels, or the prevalence of ferritin deficiency, multivariate regression models were used. Results: The prevalence of ferritin deficiency was 44.5% (95% CI 40.1% to 49.0%), serum ferritin levels ranged from 4 µg/L to 295.7 µg/L, with a average of 29.3 µg/L (95% CI 26.5 µg/L - 32.2 µg/L). Pregnant women in the second (OR (OR 2.19 95% CI 1.50 to 3.19) and third trimester (OR 3.84 95% CI 2.68 to 5.50), those residing in the Atlantic region ( OR 2.18 95% CI 1.25 to 3.82) and in the Orinoquia region (OR 2.41 95% CI 1.19 to 4.88), showed an association with ferritin deficiency. Conclusion: A high prevalence of ferritin deficiency was found in Colombian pregnant women.

RÉSUMÉ

Diabetes mellitus(DM)is a common metabolic disease,and its hyperglycemia can induce many complications and even threaten human health and life.Ferritinophagy,currently a research focus,has been proven to be related to the occurrence and development of DM and its complications.Ferritinophagy,which is cell-selective,is mediated by nuclear receptor coactivator 4(NCOA4),which degrades ferritin in autophagosomes and releases excessive iron ions so that irons are overloaded and ROS are accumulated.This process contributes to the upstream ferroptosis.This article reviews the mechanism of ferritinophagy and its pathogenesis in DM and its complications,and further analyzes the effects of regulated ferritinophagy on DM and its complications,pro-viding new insight into the prevention and treatment of DM and its complications.

RÉSUMÉ

Ferroptosis is an iron-dependent form of regulated cell death,which is distinct from apoptosis,ne-crosis,and pyroptosis.Recent studies have found that activators of ferroptosis,such as Erastin,can activate autophagy-re-lated proteins,induce the formation of autophagosomes,and ultimately release ferric ions to mediate ferroptosis.This pro-cess,called ferritinophagy,is initiated by the binding of an autophagic cargo receptor protein,nuclear receptor coactivator 4(NCOA4),to iron-laden ferritin.The transfer of NCOA4-ferritin to the lysosome by ferritinophagy results in the proteoly-sis of ferritin,and,in turn,the release of its iron content and lipid-reactive oxygen species(ROS)accumulation.Ferritin-ophagy has been closely associated with central nervous system disorders,circulatory system diseases,and cancer.Fur-thermore,the regulation mechanism of ferritinophagy is also a hot topic in the study of iron-dependent cell death process.With the in-depth study of ferritinophagy,great progress has been made in the study of key components of ferritinophagy as well as its molecular mechanisms and processes.However,a comprehensive summary of the methods for detecting ferritin-ophagy is still unclear.To further deepen the understanding of ferritinophagy and its detection methods,this review focus-es on the concept,characteristics,methods,and precautions during detection of ferritinophagy.This review provided ex-perimental reference for subsequent researchers and promoting the progress of research related to ferritinophagy.

RÉSUMÉ

【Objective】 To investigate the correlation of serum 25-hydroxyvitamin D3 [25-(OH)D3], albumin (ALB) and ferritin (SF) with Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) score in preschool children with malnutrition, and to analyze the predictive value of these factors on clinical outcomes, so as to provide reference for improving clinical outcomes. 【Methods】 Totally 90 preschoolers with malnutrition in Fuzhou Children′s Hospital from August 2021 to August 2022 were selected as the observation group, and 60 healthy preschool children during the same period were selected as the control group. Nutritional guidance was provided to the preschoolers for a consecutive 3-month period, followed by monitoring and recording the incidence of malnutrition and iron deficiency anemia within 3 months after treatment. 【Results】 The levels of serum 25-(OH)D3, ALB and SF were lower in the observation group compared to the control group, while the STAMP score was higher in the observation group (t=9.700, 6.047, 4.771, 26.976, P<0.05). The levels of serum 25-(OH)D3, ALB and SF in preschool children with malnutrition showed a negative correlation with the STAMP score (r=-0.813, -0.792, -0.829, P < 0.05). After 3 months of treatment, the levels of serum 25-(OH)D3, ALB and SF, as well as the difference between pre- and post-treatment levels, were lower in children with adverse clinical outcomes compared to those with good clinical outcomes (t=3.622, 2.189, 2.163, 8.704, 4.354, 5.296, P< 0.05). When the difference in serum 25-(OH)D3, ALB and SF before and after treatment was small, preschool children with malnutrition had a higher risk of adverse clinical outcomes [25-(OH)D3:OR=7.250, 95%CI: 3.008 - 17.476; ALB: OR=9.167, 95%CI: 2.954 - 28.444; SF: OR=5.730, 95%CI: 2.364 - 13.890]. The combined predictive value of serum 25-(OH)D3, ALB and SF before and after treatment had an AUC value of 0.927, higher than that of any single index. The decision curve analysis (DCA) showed that the combined prediction scheme of these factors had a clinical net benefit in predicting the clinical outcome of preschool children with malnutrition. 【Conclusions】 Low serum levels of 25-(OH)D3, ALB and SF are indicative of a higher risk of adverse clinical outcomes. Utilizing the combined prediction of these factors before and after treatment shows high accuracy in predicting clinical outcomes.

AIM: To observe the effects of Liuwei Dihuang Tang on the expression levels of ferritin, recombinant solute carrier family 7 member 11(SLC7A11), glutathione(GSH), and glutathione peroxidase 4(GPX4)in retinal of aging model rats.METHODS: A total of 45 SD rats were randomly divided into a blank group, a model group, and a traditional Chinese medicine(TCM)group, with 15 rats in each group. The blank group was intraperitoneally injected with physiological saline, while the model group and TCM group were intraperitoneally injected with D-galactose [500 mg/(kg·d)]. At the same time, the TCM group was orally administered with Liuwei Dihuang Tang [6.75 g/(kg·d)], while the blank group and model group were orally administered with equal volume of physiological saline for 8 consecutive wk. The expression levels of ferritin, SLC7A11, GSH, and GPX4 in the retinal tissues of rats in each group were detected.RESULTS: The expression of ferritin in the retinal tissue of the model group was increased compared to the blank group(P&#x003C;0.05), while the expression of GSH, SLC7A11, and GPX4 was reduced(P&#x003C;0.05). The expression of GSH, SLC7A11, and GPX4 in the retina tissue of rats in the TCM group was higher than that in the model group(P&#x003C;0.05).CONCLUSIONS: Liuwei Dihuang Tang may exert a delaying effect on retinal aging by regulating the ferroptosis pathway.

RÉSUMÉ

Objective To investigate the relationship between combined plasma ferritin and triglyceride (TG) concentrations in early pregnancy and the risk of gestational diabetes mellitus (GDM). Methods A total of 1 000 pregnant women who had antenatal care at the Sixth Hospital of Wuhan from January 2021 to January 2023 were selected as the research subjects. The cut-offs of ferritin and TG were analyzed by using unrestricted cube splines. All participants were divided into 4 groups according to the cut‐off values of ferritin and TG. Associations between combined ferritin and TG concentrations and GDM risk were estimated using multivariable logistic regression models. Results A total of 158 (15.8%) participants were diagnosed with GDM. The ferritin and TG levels in early pregnancy of pregnant women in the GDM group were significantly higher than those in the non-GDM group (P<0.05). After adjusting for potential confounders, the OR for the risk of developing GDM after combining ferritin with TG was 2.35 (1.65, 3.35). Couclusion The increase in plasma ferritin and TG concentrations in early pregnancy is positively correlated with the increased risk of GDM. Pregnant women with high plasma ferritin (˃65.7 ng/mL) and high TG (˃1.9mmoL/L) have the greatest risk of GDM.

Abstract This controlled study investigated metabolic changes in non-vaccinated individuals with Long-COVID-19, along with their connection to the severity of the disease. The study involved 88 patients who experienced varying levels of initial disease severity (mild, moderate, and severe), and a control group of 29 healthy individuals. Metabolic risk markers from fasting blood samples were analyzed, and data regarding disease severity indicators were collected. Findings indicated significant metabolic shifts in severe Long-COVID-19 cases, mainly a marked drop in HDL-C levels and a doubled increase in ferritin levels and insulin resistance compared to the mild cases and controls. HDL-C and ferritin were identified as the leading factors predicted by disease severity. In conclusion, the decline in HDL-C levels and rise in ferritin levels seen in Long-COVID-19 individuals, largely influenced by the severity of the initial infection, could potentially play a role in the persistence and progression of Long-COVID-19. Hence, these markers could be considered as possible therapeutic targets, and help shape preventive strategies to reduce the long-term impacts of the disease.

RÉSUMÉ

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.

RÉSUMÉ

SUMMARY OBJECTIVE: The aim of this study was to assess the role of elevated serum ferritin levels in the onset, pathological progression and prognosis of nonalcoholic fatty liver disease. Nonalcoholic fatty liver disease has been rapidly increasing worldwide. Despite extensive research on the pathogenesis of nonalcoholic fatty liver disease, a lack of sufficient clinical research on the relationship between nonalcoholic fatty liver disease and serum ferritin levels remains. METHODS: We analysed 968 patients with type 2 diabetes mellitus who underwent liver ultrasound examination and had their serum ferritin levels measured. The presence of nonalcoholic fatty liver disease and advanced liver fibrosis was determined through abdominal ultrasound examination and the nonalcoholic fatty liver disease fibrosis score. RESULTS: Compared to that in the non-nonalcoholic fatty liver disease group, the presence of hyperferritinemia was significantly more common in the nonalcoholic fatty liver disease group (83.3 vs. 56.3%, p=0.005). When patients with nonalcoholic fatty liver disease were stratified by the nonalcoholic fatty liver disease fibrosis score, those with advanced liver fibrosis exhibited a higher prevalence of hyperferritinemia (56.3, 78.9, and 88.9% for none, simple steatosis, and advanced fibrosis, respectively; p for trend=0.002). In multivariate logistic regression, liver fibrosis was independently associated with hyperferritinemia (odds ratio [OR] 1.45; 95% confidence interval [CI] 1.18-2.02; p=0.014), and this association remained significant in male patients after adjusting for other risk factors (OR 2.66; 95% CI 1.43-5.48; p=0.026). CONCLUSION: Identifying nonalcoholic fatty liver disease patients at a risk of developing nonalcoholic steatohepatitis and advanced fibrosis is crucial for implementing timely interventions and improving patient outcomes. This study highlights the potential utility of serum ferritin levels as a serum biomarker for identifying nonalcoholic steatohepatitis patients and those at a risk of late-stage fibrosis, particularly in male patients with nonalcoholic fatty liver disease.

La vacunación y el sexo femenino prevalecieron entre los moderados, mientras los hombres y las enfermedades crónicas entre los graves. Se manifestaron mayores niveles de los tres biomarcadores analizados en el grupo grave (Mann-Whitney p 0,5; p < 0,05). Conclusiones: La presencia de comorbilidades crónicas y de individuos no vacunados predominó entre los pacientes graves. Se demostró una estrecha correlación entre los biomarcadores analizados en ambos grupos de pacientes. Los biomarcadores mostraron capacidad discriminante entre la enfermedad COVID-19 moderada y grave(AU)


Introduction: The COVID-19 pandemic continues to challenge healthcare systems. The stratification of affected patients from biomarkers, a less invasive strategy, is still controversial. Objective: To check the discriminating capacity of ferritin, C-reactive protein and D-dimer in patients with moderate and severe COVID-19. Methods: A cross-sectional design was applied from June to November 2021. The qualitative variables and age were recorded by review of the patient's clinical records. The determination of the aforementioned biomarkers was carried out at the time of inclusion in the study using the Roche reagents in the HITACHI Cobas C 311 analyzer. The SPSS statistical program was used for analyzing dates. Results: There was a predominance of hypertensive patients in both groups. Vaccination and female sex prevailed among the moderate ones, while men and chronic diseases among the severe ones. Higher levels of the three analyzed biomarkers were observed in the severe group (Mann-Whitney test p < 0.05). The association between these was significant in both groups (Spearman correlation, p < 0.05). 366 μg/L of ferritin; 36.25 mg/L of C- reactive protein and 1.02 μg/mL of D-dimer, acceptably distinguished between severe and moderate (area under the curve ˃ 0.5; p < 0.05). Conclusions: The presence of chronic comorbidities and unvaccinated individuals predominated among severe patients. A close correlation was shown between the biomarkers analyzed in both patient groups. Biomarkers showed discriminating capacity between moderate and severe COVID-19 disease(AU)

RÉSUMÉ

Introduction:Haemoglobin levels are usually used to diagnose neonatal anaemia. By the time haemoglobin levels drop, body iron is depleted. Serum ferritinis the standard measure for assessment of iron levels in neonates and detects iron deficiency earlier than haemoglobin levels. Aims:To determine the prevalence of low haemoglobin and ferritin levels amongst term and preterm newborn babies. To determine the value of serum ferritin in the diagnosis of low iron stores amongst term and preterm newborns. Methodology:This was a cross sectional descriptive study carried out at the Neonatal Intensive Care Unit of the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria between June and December 2014. The study included 140 newborns of all birth weights delivered at the UNTH. These were categorized into preterm (gestational age <37 completed weeks) and term (gestational age ≥37 completed weeks. Babies with C-reactive protein levels > 10mg/dl, who were intra-uterine growth restricted, and whose mothers had conditions associated with low iron stores were excluded from the study. Anthropometric measurements were done for all subjects. Haemoglobin estimation and ferritin assay were carried out and the prevalence of neonatal anaemia was determined using each of these. Results:The range of haemoglobin concentration in the study population was 12.22g/gl –22.80g/dl. The mean serum haemoglobin concentrations were 15.69mg/dl ± 1.58 and 16.45 ± 1.92 in the preterm and term babies respectively (t = 2.557, P= .0116). The prevalence of low haemoglobin concentrations amongst both preterm and term babies was zero= .024). The range of serum ferritin level in the studypopulation was 20.6μg/l -296μg/l. The mean serum ferritin levels were 63.13μg/l ± 23.93 and 133.67μg/l ± 50.14 in the preterm and term babies respectively (t = 10.623, P< .001). The prevalence of low serum ferritin in the study population was 22.14%, but was higher in preterm than term babies 35.7% vs 8.6%: (OR –5.926, 95% C.I OR = 2.248 –15.619)(P<.001).Conclusion:Serum ferritin assay is more useful than haemoglobin as an indicator of anaemia during the neonatal period.

RÉSUMÉ

Background: Infective endocarditis (IE) is characterised by a concentration of infection inside the heart; it is caused by a bacterial or fungal infection of the endocardial surface of the heart; and it is linked with substantial morbidity and death.The aim of this research was to assess serum ferritin as an admission predictor of in-hospital prognosis in subjects with IE. Methods: This case control researchincluded60subjects diagnosed with IEon the basis of the modified duke's criteria.Subjects were allocated equally into two groups: group I: IE subjects who were further subdivided into two groups based on presence or absence of major adverse cardiovascular events (subgroup A: 19 patients who showed IE complications or major adverse cardiac events during hospitalization and subgroup B: 11 patients who showed a smooth course during hospitalization without major adverse cardiac events or IE complications) and IE subjects as well as age and sex matched 30 healthy subjects. Results: serum ferritin level were significantly increased in group I than group II (P value<0.05). Serum ferritin level was significantly increased in subgroup A than subgroup B (P value<0.001). serum ferritin can significantly predict bad outcome (P value<0.001) with AUC of 0.964 (95% CI: 0.881 – 0.995). At cut off >1200, serum ferritin can significantly predict bad outcome with 94.44% sensitivity, 92.86% specificity, 85% PPV and 97.5% NPV. Conclusions: Serum ferritin was significantly increased in IE subjects who experiencedproblems on admission as compared to IE subjects who didn’t.

RÉSUMÉ

Objectives: To assess intelligence Quotient (IQ) in transfusion dependent ?-thalassemia major patients using Malin Intelligence Scale for Indian Children (MISIC) and to correlate verbal IQ (VIQ), performance IQ (PIQ) and full scale IQ (FSIQ) with serum ferritin levels and annual blood transfusion requirements. Methods: Cross-sectional study design, enrolling 100 patients of transfusion-dependent ?-thalassemia aged 6 years to 15 years 11 months. IQ was assessed using MISIC. Results: Mean (SD) full scale IQ was 95.96 (7.23). IQ was ‘average’ in most of the patients. There was a significant negative correlation of serum ferritin levels with object assembly (r=-0.215, P=0.034) component of PIQ; annual blood requirement with general comprehension component of VIQ (r=-0.275, P=0.006) and age at diagnosis with PIQ (r=-0.273, P=0.006). There was a significant linear correlation of PIQ (r=0.280, P=0.005) and FSIQ (r=0.274, P=0.006) with pre-transfusion hemoglobin. Conclusion: IQ correlates with age at diagnosis and average annual pre-transfusion hemoglobin. This highlights the importance of early diagnosis and maintenance of satisfactory hemoglobin levels

RÉSUMÉ

In both the earlier waves of COVID-19 variants, severe and fatal respiratory disease like acute respiratory distress syndrome (ARDS) became more fatal in population with comorbid conditions. Therefore, early identi?cation of severe COVID-19 is very important for individual's precise management, including antiviral, oxygen support and intensive care unit (ICU) management. First case of COVID-19 got reported in the medical record of India on 30th January 2020 in a student who had returned from Wuhan, China. In 2020 and 2021 it was found that individuals with increased serum ferritin and LDH level landed up with severe and very severe COVID-19 if not treated timely and correctly. So correlation between S. Ferritin and LDH in 1st and 2nd wave was required to evaluate the condition of patients who remained admitted in critical care unit with or without comorbid conditions. This is hospital based cross- sectional observational study on 50-50 (total-100) critically ill patients admitted during 2020 and 2021 respectively. We found that In 2020 during the 1st wave serum LDH and serum Ferritin levels were signi?cantly high with the mean value of 481.65 U/L and 532.56 ng/ml respectively and in 2021 during 2nd wave serum LDH and serum Ferritin levels were again signi?cantly high with the mean value of 488.43 U/L and 667.27 ng/ml respectively. In 2020 patients with comorbid conditions showed S. LDH and Ferritin mean value of 543.47 U/L and 582.63 ng/ml respectively and in 2021 during 2nd wave it showed S.LDH and Ferritin levels mean value of 672.72 U/L and 727.38 ng/ml respectively. Both in?ammatory markers were signi?cantly more increased in the critically ill patients who presented with co-morbidities. This study will provide improved con?dence to health workers working in remote areas and COVID-19 hospitals in predicting transfer of COVID-19 patients to tertiary care hospitals for critical care management at the earliest.

RÉSUMÉ

Background: Term small for gestational age (SGA) babies are at risk for developing iron deficiency anemia. The association between maternal and infant iron stores is not clear. Objective: To assess proportion of term SGA neonates developing iron deficiency anemia by 10 weeks of age, and measure correlation between iron profile and hepcidin of babies at birth and at 10 weeks of age with maternal iron profile. Design: Prospective cohort study conducted from November, 2018 to April, 2020. Participants: 120 term SGA babies and their mothers. Intervention: Hemogram, iron profile and serum hepcidin (every fourth case) estimated in mother, cord blood and baby at 10 weeks. Babies developing anemia at 6 weeks detected by hemogram and ferritin were started on iron supplementation and excluded from the study. Outcome: Proportion of babies developing iron deficiency anemia at 10 weeks of age. Results: 35 (29.2%) of 120 term SGA babies developed anemia (hemoglobin <9 g/dL) at 6 weeks. Proportion of infants who developed iron deficiency anemia (hemoglobin <9 g/dL and serum ferritin <40 µ/dL) at 6 and 10 weeks of age was 14.2% and 23.3%, respectively. No significant correlation was found bet-ween hemoglobin, iron and hepcidin of the baby in cord blood and at 10 weeks of age with that of mothers. Serum hepcidin in babies at birth (137.5 ng/mL) were higher than maternal values (128 ng/mL). Conclusion: A significant proportion of term SGA infants developed anemia during early infancy, irrespective of maternal iron status.
