Iron therapy supplementation in inflammatory bowel disease patients with iron deficiency anemia: findings from a real-world analysis in Italy

BACKGROUND

This real-world analysis evaluated iron therapy supplementation in inflammatory bowel disease patients with iron-deficiency anemia, considering disease progression and healthcare resource consumption.

METHODS

A retrospective observational study was conducted using administrative databases of a pool of Italian healthcare entities, covering about 9.3 million beneficiaries. Between January 2010 and September 2017, adult patients were enrolled in the presence of either hospitalization or active exemption code for ulcerative colitis/Crohn's disease, or one vedolizumab prescription. Iron-deficiency anemia was identified by at least one prescription for iron and/or hospitalization for iron-deficiency anemia and/or blood transfusion (proxy of diagnosis). Patients were divided in untreated and iron-treated during 12-month follow-up and analyzed before and after propensity score matching. Disease progression, was evaluated through inflammatory bowel disease-related hospitalizations and surgeries, and healthcare resource utilization was assessed.

RESULTS

Overall, 1753 patients were included, 1077 (61.4%) treated with iron therapy and 676 (38.6%) untreated. After propensity score matching, 655 patients were included in each group. In unbalanced cohorts, disease progression was significantly reduced in patients receiving iron therapy compared to the untreated (11.0% vs. 15.7%, P  < 0.01), and this trend was maintained also after applying propensity score matching. The overall mean cost/patient was significantly lower in iron-treated than untreated (4643€ vs. 6391€, P  < 0.01).

CONCLUSION

The findings of this real-world analysis suggest that iron therapy was associated with significant benefits in inflammatory bowel disease patients with iron-deficiency anemia, in terms of both disease progression and healthcare resource utilization.

Safety and efficacy of East Asian herbal medicine for iron deficiency anemia in children and adolescents: a systematic review and meta-analysis

Background

This systematic review and meta-analysis aimed to evaluate the efficacy and safety of East Asian herbal medicine (HM) for iron deficiency anemia (IDA) in children and adolescents.

Methods

Twelve electronic databases were searched in 28 May 2023 for randomized controlled trials (RCTs) evaluating the efficacy of HM in children with IDA. The primary outcome measures for treatment included blood hemoglobin and serum ferritin levels, whereas the secondary outcomes included the total effective rate (TER), incidence of adverse events (AEs), average healing time, and hematologic indicators related to IDA. Meta-analysis was performed using Review Manager 5.4 and R studio 4.3 software, and subgroup analyses were performed according to the different groups (type of intervention and duration of treatment). The effect size measures used were the risk ratio, mean difference, and standardized mean difference with 95% confidence intervals. The risk of bias was assessed using a revised Cochrane risk of bias tool for randomized trials, and the quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation tools.

Results

The meta-analysis included 28 studies. Five studies compared the efficacy of HM alone with that of oral iron alone, whereas 23 compared the efficacy of a combination of HM and oral iron with that of oral iron alone. The meta-analysis revealed that the HM treatment group showed significant improvements in all outcome measures compared to those observed in the oral iron group. Moreover, HM significantly reduced the incidence of gastrointestinal AE, compared to that associated with oral iron. Among the 28 studies, the most commonly used HM prescription was Xingpi Yanger Granules, and the most commonly used botanical drug was Astragali Radix, followed by Atractylodis Rhizoma Alba and Angelicae Sinensis Radix.

Conclusion

This meta-analysis identified evidence of the efficacy and safety of HM in children with IDA. Compared to conventional oral iron therapy, HM improved IDA-related blood markers and TER, with fewer AEs and shorter mean healing times. However, further well-designed, large-scale clinical trials are necessary to strengthen the evidence of the efficacy and safety of botanical drugs.

Intravenous iron infusions in pediatric patients: A retrospective review of efficacy and safety

Pediatric iron deficiency anemia (IDA) is often treated with oral iron supplementation as the first-line therapy despite poor adherence. This single-institution retrospective chart review of pediatric patients was conducted to assess the safety, efficacy, and adherence of intravenous (IV) iron infusions compared to oral iron therapy in patients who had failed a trial of oral iron supplementation. We reviewed medical records of patients aged 1-21 with IDA who received at least one IV iron infusion at Cooper University Hospital between 2016 and 2021. Paired t-tests compared pre-infusion and post-infusion hematologic indices of hemoglobin (Hgb), mean corpuscular volume, red blood cell count, red cell distribution width, ferritin, total iron binding capacity, iron stores, and iron saturation. We compared adherence and adverse reactions to both oral iron supplementation and IV iron infusions using McNemar's test. A total of 107 subjects were included (mean age of 12.7 years). Hgb, ferritin, iron, and iron saturation between pre-infusion and post-final infusion significantly improved (p < 0.001). Hgb, ferritin, and iron improved when subcategorizing by race and etiology of IDA. Adherence to IV iron infusions (70.1%) was significantly greater than adherence to oral iron therapy (43.0%). There were also significantly fewer adverse effects with IV iron infusions (3.7%) compared to oral iron (77.9%). We demonstrated the safety, efficacy, and improved adherence of IV iron infusions compared to oral iron supplementation for treatment of pediatric IDA in patients who were unable to tolerate oral iron supplementation. Future studies could compare adherence to multiple doses of IV iron infusions in contrast with other single-dosing IV iron formulations.

Thrombin generation assay in platelet-poor plasma in children with iron deficiency anemia

OBJECTIVES

Iron deficiency anemia (IDA) is the most common type of anemia in childhood and it leads to a hypercoagulable state. We investigated endogenous thrombin production in platelet-poor plasma before and after oral iron replacement in children with IDA using the thrombin generation assay (TGA).

METHODS

A total of 72 children diagnosed with IDA (IDA group) and 60 healthy children (control group) were included in the study. Blood samples were collected from the patients before and 1 month after oral iron replacement. TGA parameters [lag time, time to peak, peak height, endogenous thrombin potential (ETP)] were studied.

RESULTS

In the IDA group, the lag time and time to peak decreased by 8.3% and 10.6%, respectively, and the endogenous thrombin potential (ETP) and peak height both increased by 30% compared to those of the control group. Compared to the values before iron replacement, 1 month after iron replacement, the lag time and time to peak increased by 8.7% and 5%, respectively, and the ETP and peak height decreased by 31% and 31.3%, respectively, and became similar to those of the control group.

CONCLUSION

Children with IDA have increased endogenous thrombin production in platelet-poor plasma and a tendency for hypercoagulability. These changes are reversible, and the ETP values become similar to those of healthy children 1 month after iron replacement.

Assessment of fetal cardiac functions in pregnant women with anemia: prospective, case-control study

OBJECTIVE

To compare the fetal cardiac functions between pregnant women with iron deficiency anemia (IDA) and healthy controls.

METHODS

This single-center, prospective, case-control study was conducted at a tertiary hospital. A total of 150 patients, including 50 patients with IDA and 100 healthy pregnant women at 30-34 weeks of gestation, were included in the study. Of the patients with anemia, 20 had mild anemia, 18 had moderate anemia, and 12 had severe anemia. Pulsed-wave Doppler, M-mode, and tissue Doppler imaging (TDI) were performed to evaluate fetal cardiac functions. The fetal cardiac score was calculated using the systolic, diastolic, and global hemodynamic function parameters.

RESULTS

The myocardial performance index and isovolumetric relaxation time were significantly higher in the IDA group than the control group, while isovolumetric contraction time was similar. Among the tricuspid and mitral valve diastolic parameters, the E, A, and E/A values were significantly lower in the IDA group (p<0.001). Mitral and tricuspid annular plane systolic excursions (MAPSE and TAPSE, respectively) were significantly lower in the IDA group (p<0.001). The IDA group also had significantly lower values for the TDI parameters, mitral and tricuspid E', A', S', E'/A' and a significantly higher E/E' ratio (p<0.001). Upon examination of anemia subgroups, a significant decrease was observed in the tricuspid and mitral A, E, and E/A in those with severe anemia (p<0.001). M-mode Doppler analysis revealed significantly lower TAPSE and MAPSE in the patient group with severe anemia. According to the subgroup comparison of TDI findings, the patients with severe anemia had significantly lower tricuspid and mitral E', A', S' and E'/A' (p<0.001) values and a significantly higher E/E' ratio (p<0.001). The fetal cardiac score was significantly higher in the maternal IDA group compared to the control group. A significant negative correlation was found between maternal hemoglobin level and fetal cardiac score (p<0.001).

CONCLUSIONS

There may be changes in the systolic and diastolic cardiac functions of the fetuses of pregnant women with IDA. This study showed an increased E/E' ratio in the fetuses of pregnant women with IDA, suggesting a decrease in fetal heart maturation. Within the IDA group, fetal cardiac functions were more affected in those with severe anemia. This article is protected by copyright. All rights reserved.

Does millet consumption contribute to raising blood hemoglobin levels compared to regular refined staples?: a systematic review and meta-analysis

Millets are recognized for their health and nutritional values, and the United Nations declared 2023 the International Year of Millets. Among the several health and nutritional benefits of millets, their impact on hemoglobin concentration is important since anemia is a major public health issue in many countries. To investigate the effect of millet (including sorghum) consumption on hemoglobin concentration in the blood, a systematic review and meta-analysis were conducted. Thirteen published studies featuring randomized control trials involving 590 individuals in the intervention group and 549 control individuals were eligible for the meta-analysis. The difference-in-differences analysis revealed highly significant (p < 0.01) positive effects of millet consumption on hemoglobin concentration, with an effect size of +0.68 standardized mean difference units. The change in hemoglobin concentration observed in the intervention group was +13.6%, which is statistically significant (p < 0.0005), compared to that in the control group, which was +4.8% and not statistically significant (p = 0.1362). In four studies, the consumption of millets in the intervention group demonstrated a change from mild anemia to normal status among children, whereas there was no change in the control group. The findings provide evidence that the consumption of millets can improve blood hemoglobin concentration, likely resulting from increased iron intake. Further research is needed involving the assessment of iron content and bioavailability to better understand the effect variation among millet types and the mechanisms involved.

Endoscopic findings and predictors of gastrointestinal lesions in children with iron deficiency anemia

Iron deficiency anemia (IDA) can be caused by occult gastrointestinal (GI) blood loss; however, the endoscopic findings in children with anemia are unclear. The study aimed to determine the frequency and factors related to lesions in children with IDA undergoing endoscopy. We retrospectively analyzed the clinical and endoscopic findings of children with a laboratory-based diagnosis of IDA. Of 58 patients, 36 (62.1%) had upper GI tract lesions, with erosive gastritis being the most common lesion. Further, 26 patients underwent concomitant colonoscopy, and 12 (46.2%) had lower GI tract lesions. Overall, 44 (75.9%) patients had lesions in either the upper or lower GI tract. Helicobacter pylori infection was detected in 13 patients (22.4%). Patients with lesions found by endoscopy had significantly lower hemoglobin level (8.9 vs. 10.0 g/dL, p = 0.047) and mean corpuscular volume (75.5 vs. 80.9 fL, p = 0.038). The proportion of patients with previous treatment for IDA was also higher in those with lesions on endoscopy. In multivariate analysis, age of ≥10 years (odds ratio [OR], 6.00; 95% confidence Interval [CI], 0.56-10.75) and positive fecal occult blood test (FOBT) findings (OR, 2.25; 95% CI, 0.14-4.52) were factors related to GI lesions. The presence of GI symptoms was not associated with GI lesions. A high proportion of GI lesions were found by endoscopy in children with IDA in this study. Endoscopy should be considered in children with IDA even without GI symptoms, especially in older children, and those with positive FOBT results.

Effect of IV ferric carboxy maltose for moderate/severe anemia: a systematic review and meta-analysis

Introduction

Anemia remains a prevalent global health issue with varying severity. Intravenous iron supplementation, particularly with ferric carboxymaltose (FCM), has appeared as a possible therapeutic intervention for individuals with moderate to severe anemia. The study aimed to assess the efficacy and safety of ferric carboxymaltose (FCM) in reducing anemia.

Methods

We searched electronic databases, registries, websites, e-libraries, reference lists of reviews, citations, etc. We included randomized control trials (RCTs), non-RCTs, and single-arm studies, while observational studies, case series, and case studies were excluded. Two reviewers independently screened the studies and extracted the data. We included studies of moderate-to-severely anemic Indians and excluded Indians with other comorbidities. We assessed the risk of bias and the overall quality of evidence (QoE) using GRADE GDT.

Result

We identified 255 studies and included 14 studies (11 RCT, one non-RCT, and two single-arm studies) with 1,972 participants for qualitative analysis and 10 studies in the meta-analysis. All the included studies detailed the use of FCM for anemia. The primary outcomes assessed in the included studies were anemia, hemoglobin, and adverse events. The outcomes assessed ranged from 2 weeks to 12 weeks. The risk of bias varied across different studies with different outcomes. FCM is consistent with a fewer number of adverse events as compared to other interventions and provides "moderate" to "very low" QoE.

Conclusion

A slow single infusion of 1 gram of FCM is well-tolerated, safe, and effective in treating iron deficiency anemia (IDA) and surpasses other interventions (Iron Sucrose Complex (ISC), Iron sucrose, and ferrous ascorbate) in elevating hemoglobin levels and replenishing iron stores.

Iron Deficiency and Vitamin D Deficiency Are Associated with Sleep in Females of Reproductive Age: An Analysis of NHANES 2005-2018 Data

BACKGROUND

Iron and vitamin D deficiencies have been implicated in sleep disturbance. Although females are more susceptible to these deficiencies and frequently report sleep-related issues, few studies have examined these associations in females.

OBJECTIVE

This study investigates the association of iron and vitamin D deficiencies on sleep in a nationally representative sample of females of reproductive age.

METHODS

We used 2 samples of 20-49-y-old non-pregnant females from National Health and Nutrition Examination Survey (NHANES) 2005-2008 (N = 2497) and NHANES 2005-2010 and 2015-2018 (N = 6731) to examine the associations of iron deficiency (ID), iron deficiency anemia (IDA), vitamin D deficiency (VDD), vitamin D inadequacy (VDI), and the joint association of both deficiencies with sleep duration, latency, and quality. Sleep outcomes were measured using a self-reported questionnaire. We used the body iron model based on serum ferritin and serum soluble transferrin receptor to identify ID, along with hemoglobin to identify IDA cases. In addition, 25-hydroxyvitamin D levels were used to determine VDD and VDI cases. Logistic regression was used to evaluate these associations, adjusting for potential confounders. In addition, we assessed the multiplicative and additive interactions of both deficiencies.

RESULTS

ID and IDA were associated with poor sleep quality, with 1.42 [95% confidence interval (CI): 1.02, 2.00)] and 2.08 (95% CI: 1.29, 3.38) higher odds, respectively, whereas VDD and VDI were significantly associated with short sleep duration, with 1.26 (95% CI: 1.02, 1.54) and 1.22 (95% CI: 1.04, 1.44) higher odds, respectively. Subjects with both nutritional deficiencies had significantly higher odds of poorer sleep quality compared with subjects with neither condition. For sleep quality, a significant multiplicative interaction was observed between ID and VDD (P value = 0.0005). No associations were observed between study exposures and sleep latency.

CONCLUSIONS

Among females of reproductive age, iron and vitamin D deficiencies are associated with sleep health outcomes. The potential synergistic effect of both deficiencies warrants further assessment.

Reticulocyte hemoglobin equivalent as a marker to assess iron deficiency: A large pediatric tertiary care hospital study

INTRODUCTION

Detection of iron deficiency (ID) remains challenging. We aimed to evaluate the performance of reticulocyte hemoglobin equivalent (Ret-He) as a potential diagnostic marker to assess ID and iron deficiency anemia (IDA) in a large pediatric cohort.

METHODS

A total of 3158 patients (aged 15 days to 19 years with a median age of 8.5 years; 60.2% female) were retrospectively studied. Statistical analysis was performed (a) to evaluate relationship of Ret-He with other relevant complete blood count and iron panel parameters; (b) to compare the levels of Ret-He in ID and IDA groups to a control group; and (c) to assess sensitivity and specificity of Ret-He in ID, IDA, and anemia without ID groups.

RESULTS

Ret-He values were significantly positively correlated to ferritin and transferrin saturation (TSAT). The median Ret-He was significantly lower in ID. A Ret-He cutoff of ≤30.0 pg distinguished cases of ID from the control group with a sensitivity of 90.2%, specificity of 59.5%, and area under curve (AUC) of 0.88. Ret-He showed better diagnostic performance in the IDA group and acceptable performance for ID without anemia. The sensitivity, specificity, and AUC were 90.1%, 80.9%, and 0.93 for IDA at cutoff value of ≤27.4 pg, and 80.8%, 51.1%, and 0.70 for ID without anemia at cutoff value of ≤30.8 pg, respectively.

CONCLUSION

Our large pediatric tertiary care hospital study demonstrates that Ret-He is a reliable marker to help confirm IDA in pediatric population. However, further studies are needed for its use to capture the early stages of ID.

Bilateral Sudden Hearing Loss in Iron Deficiency Anemia

The present study describes an unusual case of bilateral sudden hearing loss associated with iron deficiency anemia. Although hematologic disorders such as anemia or leukemia have been reported to be associated with sudden hearing loss, bilateral sudden hearing loss, which was presented as the first manifestation of iron deficiency anemia, has not been reported. A 74-year-old man presented with simultaneous bilateral sudden hearing loss without vertigo. A complete blood count test revealed a hemoglobin level of 6.4 g/dL and a ferritin level of 14.5 mg/mL, indicating iron deficiency anemia. Postcontrast 3D FLAIR MRI showed enhancement of the bilateral cochlea, vestibules, and lateral semicircular and posterior semicircular canals. After treatment, the patient's hearing loss partially improved.

Artificial intelligence-driven diagnosis of β-thalassemia minor & iron deficiency anemia using machine learning models

Background

Iron deficiency anemia (IDA) and b-thalassemia minor (BTM) are the two most common causes of microcytic anemia, and although these conditions do not share many symptoms, differential diagnosis by blood tests is a time-consuming and expensive process. CBC can be used to diagnose anemia, but without advanced techniques, it cannot differentiate between iron deficiency anemia and BTM. This makes the differential diagnosis of IDA and BTM costly, as it requires advanced techniques to differentiate between the two conditions. This study aims to develop a model to differentiate IDA from BTM using an automated machine-learning method using only CBC data.

Methods

This retrospective study included 396 individuals, consisting of 216 IDAs and 180 BTMs. The work was divided into three parts. The first section focused on the individual effects of hematological parameters on the differentiation of IDA and BTM. The second part discusses traditional methods and discriminant indices used in diagnosis. In the third section, models developed using artificial neural networks (ANN) and decision trees are analysed and compared with the methods used in the first two sections.

Differentinating between non-transfusion dependant β-thalassemia and iron deficinecy anemia in children using ROC and logistic regression analysis: two novel discrimination indices designed for pediatric patients

Introduction

This cross-sectional study enrolled a group of 271 children with microcytic anemia in order to test the performance of 41 single and 2 composite formulas andindices in distinguishing between β-thalassemia (β-thal) and iron deficiency anemia (IDA) in the pediatric population.

Methods

Optimal pediatric cut-off values from the previously published formulas and indices were generated using ROC analysis. Logistic regression in R using generalized linear models (GLM) generated two new indices.

Results

Formulas and indices with optimal cut-offvalues in children with accuracy ≥90% were (in descending order): Matos & Carvalho index, MDHL(Telmissani) formula, England and Fraser formula, Pornprasert index, Sirachainan index, Telmissani (MCHD) formula, CRUISE index, Hameed index, Sargolzaie formula and Zaghloul II index. The CroThalDD-LM1 index has an accuracy of 93.36% (AUC 0.986, 95% CI 0.975-0.997), while the second CroThalDD-LM2 index utilizes absolute reticulocyte count alongside CBC variables, with an accuracy of 96.77% (AUC 0.985, 95% CI 0.988-0.999).

Discussion and conclusion

We recommend using aforementioned formulas and indices with corrected cut-off values and accuracy >90% alongside two new proposed indices. A comparison of both native and these new indices is encouraged. These are the first discrimination indices generated and designed precisely for the pediatric population, which includes preschool children.

Describing and Comparing Patient Factors Associated with Use of Parenteral Iron before and after Implementation of an Order Set for Parenteral Iron (DECODE IRON)

Background

In select clinical scenarios, IV administration of iron is suitable for management of iron deficiency anemia; however, for most patients, oral administration of iron is the mainstay of treatment. At the Red Deer Regional Hospital Centre, in Red Deer, Alberta, high utilization of IV iron has resulted in limited access to this medication for the treatment of ambulatory patients, as well as significant usage of health care resources.

Objectives

The primary objective was to compare patient characteristics, specifically pretreatment laboratory test results and previous use of oral iron, among those receiving IV iron therapy in an ambulatory setting before and after implementation of an iron sucrose order set. For secondary objectives, the aforementioned groups were compared with regard to meeting the diagnostic criteria for iron deficiency anemia, with or without pretreatment oral iron or blood transfusion, and the dosing characteristics for IV iron.

Methods

A retrospective electronic chart review was performed for ambulatory patients who received IV iron between January 1, 2020, and January 31, 2022.

Results

A total of 436 unique treatment courses were included in the analysis. The following pretreatment laboratory results were observed before and after implementation of the iron sucrose order set: mean hemoglobin 105.8 (standard deviation [SD] 21.9) g/L versus 102.2 (SD 18.5) g/L; mean of mean corpuscular volume (MCV) 82.2 (SD 9.4) fL versus 79.2 (SD 8.9) fL; and median ferritin 7 (interquartile range [IQR] 4-12) μg/L versus 6 (IQR 4-11) μg/L. Only the difference in MCV values was statistically significant (p = 0.001).

Conclusions

The implementation of an iron sucrose order set for ambulatory patients did not have a significant effect on pretreatment laboratory parameters among patients for whom IV iron was prescribed. Further stewardship initiatives could be beneficial in improving the appropriateness of IV iron use.

Effects of a second iron-dextran injection administered to piglets during lactation on differential gene expression in liver and duodenum at weaning

Six female littermate piglets were used in an experiment to evaluate the mRNA expression in tissues from piglets given one or two 1 mL injections of iron dextran (200 mg Fe/mL). All piglets in the litter were administered the first 1 mL injection < 24 h after birth. On day 7, piglets were paired by weight (mean body weight = 1.72 ± 0.13 kg) and one piglet from each pair was randomly selected as control (CON) and the other received a second injection (+Fe). At weaning on day 22, each piglet was anesthetized, and samples of liver and duodenum were taken from the anesthetized piglets and preserved until mRNA extraction. differential gene expression data were analyzed with a fold change cutoff (FC) of |1.2| P < 0.05. Pathway analysis was conducted with Z-score cutoff of P < 0.05. In the duodenum 435 genes were significantly changed with a FC ≥ |1.2| P < 0.05. In the duodenum, Claudin 1 and Claudin 2 were inversely affected by + Fe. Claudin 1 (CLDN1) plays a key role in cell-to-cell adhesion in the epithelial cell sheets and was upregulated (FC = 4.48, P = 0.0423). Claudin 2 (CLDN2) is expressed in cation leaky epithelia, especially during disease or inflammation and was downregulated (FC = -1.41, P = 0.0097). In the liver, 362 genes were expressed with a FC ≥ |1.2| P < 0.05. The gene most affected by a second dose of 200 mg Fe was hepcidin antimicrobial peptide (HAMP) with a FC of 40.8. HAMP is a liver-produced hormone that is the main circulating regulator of Fe absorption and distribution across tissues. It also controls the major flows of Fe into plasma by promoting endocytosis and degradation of ferroportin (SLC4A1). This leads to the retention of Fe in Fe-exporting cells and decreased flow of Fe into plasma. Gene expression related to metabolic pathway changes in the duodenum and liver provides evidence for the improved feed conversion and growth rates in piglets given two iron injections preweaning with contemporary pigs in a companion study. In the duodenum, there is a downregulation of gene clusters associated with gluconeogenesis (P < 0.05). Concurrently, there was a decrease in the mRNA expression of genes for enzymes required for urea production in the liver (P < 0.05). These observations suggest that there may be less need for gluconeogenesis, and possibly less urea production from deaminated amino acids. The genomic and pathway analyses provided empirical evidence linking gene expression with phenotypic observations of piglet health and growth improvements.

Cytomorphometric analysis of buccal mucosal cells in iron deficiency anemia: A cross-sectional study

Background

Worldwide, at any given moment, more individuals have iron deficiency anemia (IDA) than any other health problems. Very few studies have been conducted to evaluate changes in oral mucosa in IDA. The present study is undertaken for cytomorphometric analysis of buccal mucosal cells in IDA. Nuclear diameter (ND), cell diameter (CD), nuclear area (NA), cell area (CA), and nuclear-cytoplasmic ratio (N/C) are measured and compared in buccal mucosal cells of IDA patients and controls.

Aims

To evaluate cytomorphometric changes in epithelial cells of oral mucosa in IDA and to compare these changes with the controls.

Settings and Design

A cross-sectional study.

Methods and Materials

Forty cases of IDA and forty cases of control group were selected for the study. IDA cases were diagnosed with decreased Hb level, MCV, MCH, MCHC and confirmed by decreased serum iron and increased total iron-binding capacity levels. Cytomorphometric analysis of buccal mucosa was performed to study CA, CD, NA, ND, and N/C ratio.

Statistical Analysis Used

Statistical analysis was done using t- test in SPSS software version 4.

Result

Results of our study showed increased cell area, cell diameter, nuclear area, nuclear diameter, and nuclear-cytoplasmic ratio in anemic group as compared to controls.

Conclusion

The study suggests that individuals with IDA regardless of clinically visible oral lesions show cytological changes in oral mucosal epithelium. Knowledge of quantitative alterations in oral epithelial cells of IDA patients is important as these alterations are similar to those seen in precancerous and radiation-induced changes. Cytomorphometry is an efficient tool to understand the extent of cellular changes that occur in oral epithelial cells in IDA.

Cost-utility analysis of ferric derisomaltose versus ferric carboxymaltose in patients with inflammatory bowel disease and iron deficiency anemia in England

AIMS

Anemia is the most common extraintestinal complication of inflammatory bowel disease (IBD), with approximately half of cases caused by iron deficiency (ID). Intravenous iron is the preferred ID anemia (IDA) treatment where oral iron is contraindicated, ineffective or not tolerated, or where ID correction is urgent. The objective was to evaluate the cost-utility of ferric derisomaltose (FDI) versus ferric carboxymaltose (FCM) in patients with IBD and IDA in England, in whom IV iron treatment is preferred.

MATERIALS AND METHODS

A patient-level simulation model was developed, capturing quality of life (QoL) differences based on SF-36v2 data from the PHOSPHARE-IBD randomized controlled trial, monitoring and incidence of post-infusion hypophosphatemia, and number of iron infusions required. Analyses were conducted over a five-year time horizon from the Department of Health and Social Care (DHSC) perspective, with healthcare provider and societal perspectives adopted in separate analyses. Future costs and effects were discounted at 3.5% per annum and one-way and probabilistic sensitivity analyses were performed.

RESULTS

FDI increased quality-adjusted life expectancy by 0.075 QALYs versus FCM from 2.57 QALYs to 2.65 QALYs per patient. Patients receiving FDI required 1.63 fewer iron infusions over the five-year time horizon, driving infusion-related cost savings of GBP 496 per patient (GBP 2,188 versus GBP 1,692) from the DHSC perspective. Costs of monitoring and treating hypophosphatemia after FCM were GBP 226, yielding total savings of GBP 722 per patient (GBP 2,414 versus GBP 1,692) over the five-year time horizon. FDI also led to reduced costs versus FCM in the societal and provider analyses and was therefore the dominant intervention across all three perspectives.

LIMITATIONS

The analysis did not capture patient adherence, hypophosphatemic osteomalacia, or fractures.

CONCLUSIONS

Results showed that FDI improved patient QoL and reduced direct healthcare expenditure versus FCM in patients with IBD and IDA in England.

Correlation of Anemia Due to Poor Iron Status With Obesity at King Fahad Medical City, Riyadh, Saudi Arabia

Background Saudi Arabia has a high prevalence of chronic diseases such as obesity. Moreover, iron deficiency anemia (IDA) in developing countries is the most prevalent type of anemia. This study aims to assess the correlation between anemia related to poor iron status and obesity. Methods A cross-sectional observational study was conducted at the obesity center in King Fahad Medical City, Saudi Arabia, from April to September 2020. Two hundred and forty participants were needed to be included in the study. The data was gathered by utilizing a designed data collection form. Socio-demographic data, weight and height, questions related to the history of anemia, and gynecological data (for females) were collected. The data was analyzed using SPSS (Statistical Package for Social Science) version 28.0. Descriptive statistics were used to present numerical and categorical data and a Chi-square test was conducted to assess the correlation between categorical variables. Informed written consent was obtained from all participants and ethical approval was obtained from the Ethical Board Committee in King Fahad Medical City. Results The study included 240 participants. Two-thirds of the study population are females (64.6%), 66.7% are married, and 65.8% have obesity. Almost one-half of the study population (46%, N=128) was diagnosed with IDA with malnourishment being the most common reason for IDA (88.2%). The results indicated a correlation between obesity and the prevalence of IDA. The prevalence of IDA among participants with obesity (60.4%) was significantly higher compared to non-obese participants (39.5%), p=0.002. The study found that females and underweight individuals have a higher prevalence of IDA (p<0.001). Conclusion Results of the present study suggest that obesity could be associated with a risk of IDA. In addition, Saudi women could be more prone to IDA than men. Further prospective controlled studies among diverse populations in Saudi Arabia including laboratory assessment of inflammatory markers and iron status are required to better understand the correlation between obesity and IDA.

Survival After Wait-and-See Approach in Older Patients With Unexplained Iron Deficiency Anemia in Primary Care: A Practice Evaluation

OBJECTIVES

Guidelines recommend upper and lower gastrointestinal endoscopic evaluation for patients without a clear physiological explanation for iron deficiency anemia (IDA). However, the consequences of watchful waiting in older patients with unexplained IDA in general practice are unknown. The aim of this study was to investigate characteristics and survival of patients with an unexplained IDA in general practice who refrain from medical specialist evaluation.

DESIGN

Historical prospective study.

SETTING AND PARTICIPANTS

Patients aged ≥70 years with IDA coded in their medical records were selected from the Dutch Academic General Practitioner Development Network (AHON) database.

METHODS

Based on their medical records, patients with an unexplained IDA were classified as (1) referred for medical specialist evaluation, or (2) no or noninvasive evaluation in general practice.

RESULTS

Compared to patients who were referred for medical specialist evaluation (n = 235, 47.8%), patients who had no or noninvasive evaluation (n = 257; 52.5%) were older (median respectively 79 vs 82 years old, P < .01) and more likely to have congestive heart failure (respectively 17.4% and 26.1%, P = .02) and dementia (respectively 2.6% and 8.9%, P < .01). Two-year survival was significantly higher in patients who were referred for medical specialist evaluation compared to patients who had no or noninvasive evaluation (respectively, 83.9% and 75.5%, P = .02).

CONCLUSIONS AND IMPLICATIONS

Although mortality was significantly higher in the older and more comorbid patients who had no or noninvasive evaluation in general practice, survival was still high in this patient group. Therefore, non-guideline adherence and a wait-and-see approach could be discussed in a shared-decision-making consultation.

Prevalence of Undiagnosed Iron Deficiency Anemia and Associated Factors Among Female Undergraduate Medical Students in Makkah, Saudi Arabia

INTRODUCTION

Iron deficiency anemia is the most common type of anemia according to the World Health Organization. Females are more likely to be affected than males. There are several factors causing iron deficiency anemia, such as increased loss of iron, decreased intake of iron, and increased utilization of iron. There are limited research studies evaluating the risk factors that cause anemia among female medical students in Saudi Arabia. For this, the study aimed to identify the prevalence of undiagnosed iron deficiency anemia (IDA) among young female university students and to identify if there is any correlation between IDA and several factors including dietary habits, psychological stress, anxiety status, and body mass index.

MATERIALS AND METHODS

A cross-sectional observational study was performed between October 2022 and December 2022 with a sample of 100 healthy female students aged between 19 and 23 years, who were studying at the medical colleges of Umm Al-Qura University, Saudi Arabia. Blood samples were collected to perform complete blood count and iron profile tests. Also, a survey was done to find correlation between iron deficiency anemia and dietary intake, drinks, stress, anxiety, and body mass index (BMI). Independent t-test or Mann-Whitney U test were used to compare values for non-anemic with anemic participants, and linear regression tests were used to analyze differences between non-anemic and anemic participants' dietary intake factors and stress and anxiety scores. The level of significance was set at p<0.05.

RESULTS

The findings represent an overall prevalence of iron deficiency anemia in female medical students based on the lab finding results. Thus, students were divided into two following groups: anemic (13%) with hemoglobin (Hb) concentration <12 g/dL and non-anemic (84%) with Hb concentration ≥12 g/dL. When comparing the two groups, results showed significant differences in the majority of RBC indices (hematocrit {HCT}, mean corpuscular volume {MCV}, mean corpuscular hemoglobin {MCH}, red cell distribution width {RDW}) and iron profiles, p-value was <0.05. On evaluation of the different types of food consumption, the mean iron intake was around 7 mg/day, and in 65% of the participants, it was below the estimated average requirement (EAR) of iron (8.1 mg/dL). The perceived stress scale (PSS) shows that 63% of the participants experienced moderate stress and 58% reported severe anxiety by the generalized anxiety disorder (GAD) scale. In multiple linear regression, iron was positively associated with hemoglobin concentrations, whereas stress scores were negatively associated with hemoglobin concentrations.

CONCLUSION

There is a relatively low prevalence of anemia and most of it was found of the microcytic type, indicating that this condition is a common health issue among local female college students. There was no independent association between stress or anxiety and hemoglobin levels.

Hemochromatosis in an Adult Female With Previous Iron Deficiency Anemia on Iron Supplementation

A 56-year-old female presented with a diagnosis of iron deficiency anemia over three years prior (on oral iron supplementation) and presented with altered mental status. She was admitted to the Coronary Care Unit for troponinemia and T-wave inversions. Two-dimensional echocardiography revealed hypokinesia of the left ventricle (LV) anterior wall with reduced ejection fraction. The patient was stabilized on metoprolol and heparin infusions, but heparin was discontinued after iron studies revealed overload (iron: 159 ug/dL, 100% saturation, ferritin: 1480 ng/mL). Cardiac MRI revealed mixed concentric-eccentric LV hypertrophy, raising concern for severe iron overload. Mutation analysis of the HFE  (homeostatic iron regulator) gene responsible for hereditary hemochromatosis was negative for a homozygous mutation. Hematology was consulted to establish outpatient follow-up and consider treatments for the acquired hemochromatosis. Acquired hemochromatosis typically occurs in the setting of multiple blood product transfusions. Oral supplementation is typically mitigated by limited bioavailability. Follow-up was needed to track the patient's iron deficiency anemia and identify resolution and potential toxicity. Further research into predisposing factors for hemochromatosis in patients on oral supplementation without HFE mutations is indicated.

Maternal and Neonatal Outcomes of Iron Deficiency Anemia: A Retrospective Cohort Study

INTRODUCTION

Understanding the outcomes of anemia in pregnancy is critical. Since no study has been conducted regarding the maternal and neonatal outcomes of iron-deficiency anemia in Hormozgan province of Iran, this study aims to assess the maternal and neonatal outcomes of iron-deficiency anemia in women who gave birth in Hormozgan province from January 2020 to January 2022.

METHODS

 We retrospectively assessed all singleton pregnant women who gave birth at a tertiary hospital in Bandar Abbas, Hormozgan province, Iran, for two years. We divided all women into iron-deficiency anemic and non-iron-deficiency anemic women. Iron-deficiency anemia was defined as hemoglobin less than 10.5 mg/dl at the time of admission without any other hemoglobinopathy, such as sickle cell anemia or thalassemia. Using electronic patient records, data were extracted from the Iranian Maternal and Neonatal Network (IMaN Net), a valid national system. Since the information of birth under 24 weeks of gestation is not recorded in this system, we excluded all deliveries under 24 weeks of gestation. The outcome measures of the study were demographic factors (age, education, residency place, access to prenatal care, smoking), obstetrical factors (parity, labor induction, fetal presentation, mode of delivery), and maternal and neonatal outcomes (the incidence of preeclampsia, gestational diabetes, placenta abruption, postpartum hemorrhage, maternal need for blood transfusion, maternal need for intensive care unit, preterm birth, low birth weight, intrauterine growth retardation, birth asphyxia, stillbirth, and neonatal intensive care admission). Chi-square tests were used to compare differences between iron-deficiency anemic and non-iron-deficiency anemic women. Logistic regression models were used to assess the effect of iron-deficiency anemia on maternal and neonatal outcomes. The result was presented as odds ratio (OR) or adjusted odds ratio (aOR) after adjusting for covariates and a 95% confidence interval (CI).  Results: The incidence of iron-deficiency anemia was 2.97%. Education and residency were among the demographic factors that differed significantly between groups. Iron-deficiency anemia was more frequent in those with higher education and women who lived in rural areas. In terms of obstetrical factors, method of delivery was the only significantly different factor between groups. Iron-deficiency anemic mothers had substantially more instrumental deliveries than non-iron-deficiency anemic mothers (4.3% vs. 0.8%), while the incidence of cesarean section was lower. Based on logistic regression in terms of maternal and neonatal outcomes, iron-deficiency anemic women had a substantially higher risk of the need for maternal blood transfusion (aOR: 6.54, 95%CI: 4.72-8.15), postpartum hemorrhage (aOR: 1.54, 95%CI: 0.71-2.11), preterm birth (aOR: 0.98, 95%CI: 0.45-1.13), low birth weight (aOR: 1.04, 95%CI: 0.78-2.01), intrauterine growth retardation (aOR: 1.30, 95%CI: 0.99-2.10), and neonatal intensive care admission (aOR: 1.06, 95%CI: p.52-2.72), after adjusting for educational level, residency place, and method of delivery.

CONCLUSIONS

Despite the higher incidence of postpartum hemorrhage and maternal blood transfusion, we found no increase in maternal intensive care unit admission risk. Regarding neonatal outcomes, iron-deficiency anemia was linked to preterm birth, low birth weight, intrauterine growth retardation, and neonatal intensive care admission.

Assessing the occurrence and severity of pre- and postendodontic pain in anemic and healthy female patients

OBJECTIVES

The objective of this current survey was to assess both the occurrence and severity of pre- and post-endodontic pain among female individuals, distinguishing between those with anemia and those without.

MATERIALS AND METHODS

In the current study, we included a total of 60 women with anemia (hemoglobin < 11) and those without anemia (hemoglobin > 13). We recorded the occurrence and severity of pain before and at 24, 48, and 72 h following root canal treatment using a visual analog scale (VAS) ranging from 0 to 10. Additionally, we collected data on patient age, tooth type, as well as pulpal and periapical conditions. Statistical analysis was carried out using two-way ANOVA, pairedt-tests, and Pearson correlation coefficient. The significance level for statistical tests was set at p ≤ .05.

RESULTS

The incidence of preoperative pain in both anemic and non-anemic patients was 80%. The total incidence of post-operative pain was recorded as 71.7% (82.2% in anemic and 61.1% in non-anemic women). Compared with the pretreatment pain incidence and intensity, the values increased in 24 h but declined in 48 h and 72 h after treatment. Considering the posttreatment pain intensity, the mean values were higher in the three time intervals (24, 48, and 72 h) in anemic patients. Pulpal and periapical status, in contrast to age and tooth type, significantly contributed to the intensity of posttreatment pain.

CONCLUSION

Regarding the importance of pain phenomenon in human life, it is recommended to consider anemia as an important risk factor for post-endodontic pain. Early diagnosis and analgesic treatment interventions in anemic females, alongside the pain control during root canal treatment, could promote the patient's satisfaction and quality of care.

Iron Surveillance and Management in Gastro-Intestinal Oncology Patients: A National Physician Survey

PURPOSE

Iron deficiency (ID) is a complication of gastrointestinal (GI) cancers that may manifest as iron deficiency anemia (IDA). Serum ferritin monitoring and oral iron supplementation have the limitations of being falsely elevated and poorly absorbed, respectively. This study aims to assess the discordance in surveillance, treatment practices, and awareness of ID/IDA in GI cancer patients by Canadian physicians treating these patients.

METHODS

From February 2020 to September 2021, a 22-question electronic survey was sent to medical oncologists (MOs), surgical oncologists (SOs), and gastroenterologists (GEs). The survey collected information about four domains: physician demographics, surveillance practices, treatment practices, and awareness of ID/IDA in GI cancer patients and ASCO/ASH guidelines.

RESULTS

A total of 108 (34 MOs, 19 SOs, and 55 GEs) of the 872 (12.4%) invited physicians completed the survey. Of these, 26.5% of MOs, 36.8% of SOs, and 70.9% of GEs measured baseline iron parameters, with few continuing surveillance throughout treatment. Ferritin was widely measured by MOs (88.9%), SOs (100%), and GEs (91.4%). Iron was supplemented if ID/IDA was identified pre-treatment by 66.7% of MOs, 85.7% of SOs, and 94.2% of GEs. Parenteral iron was prescribed by SOs (100%), while oral iron was prescribed by MOs (83.3%) and GEs (87.9%). Only 18.6% of physicians were aware of the ASCO/ASH guidelines regarding erythropoiesis-stimulating agents with parenteral iron for treating chemotherapy-induced anemia.

CONCLUSION

Results illustrate variations in practice patterns for IDA management across the different physician specialties. Moreover, there appeared to be gaps in the knowledge and care surrounding evidence-based IDA management principles which may contribute to poor clinical outcomes.

Gastric and colonic metastases of malignant melanoma diagnosed during endoscopic evaluation of symptomatic anemia presenting as angina: a case report

A 72-year-old man visited cardiology for exertional chest pain, lightheadedness, and fatigue. Six years prior, he was surgically treated for cutaneous malignant melanoma of the lower back. After a negative cardiac work-up, primary care diagnosed severe iron deficiency anemia. Emergent upper and lower gastrointestinal (GI) endoscopy revealed simultaneous melanoma metastases to the stomach and colon with discrete macroscopic features. Metastatic disease, including brain, lung, and bone, was discovered on imaging. Treatment included immunotherapy with nivolumab and stereotactic radiosurgery of the brain metastases, and our patient has remained in continued remission even after 2 years. Melanoma with GI tract (GIT) metastasis has a poor prognosis and rarely presents symptomatically or with synchronous gastric and colonic lesions. This case illustrates the importance of early primary care involvement to expedite work-up for multifocal GI metastases in patients with a remote melanoma history presenting with symptoms related to iron deficiency anemia (IDA).

Literature Review and a Relevant Case of Pediatric Collagenous Gastritis: A Rare but Important Etiology of Iron-Deficiency Anemia

An adolescent male with fatigue, weight loss, and iron-deficiency anemia failed to improve with iron supplementation and a gluten-free diet. Endoscopy revealed collagenous gastritis. Pediatric patients with refractory iron deficiency and family history of autoimmune disorders should be referred to pediatric gastroenterology for evaluation of collagenous gastritis and celiac disease.

Two Novel α-Thalassemia Mutations CD 39 -C [Thr > Pro] and CD 109 ACC > CCC [Thr > Pro] Identified in Two Chinese Families: A Case Report

We reported the identification of two rare α-thalassemia silent carriers with novel HBA1 mutations of CD 39 -C [Thr > Pro] (HBA1: c.114del; p.Thr39Profs*11) and CD 109 ACC > CCC [Thr > Pro] (HBA1: c.325A > C; p. Thr109Pro), respectively. The two probands were pregnant women diagnosed with mild hypochromic anemia or microcytic hypochromic anemia by routine blood tests. They started iron therapy before taking differential diagnosis from iron deficiency anemia. After wait and watch approach, they both accepted thalassemia genetic screening, which identified CD 39 -C [Thr > Pro] and CD 109 ACC > CCC [Thr > Pro], respectively. Due to inappropriate iron therapy, worse anemia and iron overload were noticed in the first proband, but no obvious side effect was found in both probands. Functional analysis showed that, relative to the wild type, CD 39 -C [Thr > Pro] considerably reduced the expression of the HBA1 protein while CD 109 ACC > CCC [Thr > Pro] only had a minor impact. Our study highlighted the importance of gestational thalassemia screening based on next-generation sequencing for identifying novel rare thalassemia variants and increased our understanding about the relationship between genotype and phenotype of α-thalassemia.

Implications of Iron Deficiency Anaemia on Glycemic Dynamics in Diabetes Mellitus: A Critical Risk Factor in Cardiovascular Disease

BACKGROUND

Iron deficiency anemia (IDA) is a highly prevalent comorbidity in patients with diabetes, with rates estimated between 13% and 47% across studies. Iron deficiency anemia may potentially influence hemoglobin A1c (HbA1c) values, which are routinely measured to monitor long-term glycemic control in diabetes. Some evidence suggests that HbA1c may be lower in diabetics with IDA due to increased red blood cell turnover. However, current evidence elucidating the effects of IDA on HbA1c and diabetes outcomes remains inconsistent and inconclusive.

OBJECTIVE

This cross-sectional study aimed to evaluate the relationship between IDA, HbA1c levels, and glycemic dynamics in patients with diabetes mellitus.

METHODS

The study sample included 143 adult patients diagnosed with diabetes, recruited from outpatient clinics in Saudi Arabia. Iron deficiency anemia was identified through serum ferritin <100 ng/mL, transferrin saturation <20%, and hematologic parameters. The HbA1c levels were measured using standardized laboratory methods. Daily glucose profiles were obtained by continuous glucose monitoring (CGM) in a subset of patients to assess glycemic dynamics.

RESULTS

The prevalence of IDA was 39.9% among the diabetic cohort. Patients with IDA had a numerically higher mean HbA1c of 7.2% compared to 6.8% in non-anemic diabetics, suggesting a potential effect of IDA on HbA1c. Those with IDA also spent more time in hyperglycemic ranges, along with greater glucose variability based on CGM data. Iron deficiency measures, including low ferritin and high red cell distribution width (RDW), showed weak positive correlations with HbA1c levels.

CONCLUSION

Iron deficiency anemia is highly prevalent among Saudi diabetic patients and is potentially associated with inaccurate HbA1c values and poor short-term glycemic control. However, larger controlled studies are warranted to conclusively investigate mechanisms linking IDA to alterations in HbA1c and glycemic dynamics. Optimized screening and treatment of IDA may lead to more accurate diabetes monitoring and improved outcomes.

Expert consensus on improving iron deficiency anemia management in obstetrics and gynecology in Asia

Iron deficiency anemia (IDA) is a major health burden among women in Asia. Key issues in IDA management in Asia are under-diagnosis and under-treatment. The lack of Asia-specific guidelines, and suboptimal utilization of treatment compounds the management of IDA. To address these gaps, a panel of 12 experts in obstetrics, gynecology, and hematology from six regions in Asia convened to review current practices and clinical evidence and provide practical guidance on IDA diagnosis and management in Asian women. The Delphi approach was used to obtain objective opinions and attain consensus on statements pertaining to awareness, diagnosis, and management of IDA. In total, 79 statements attained consensus and are summarized to provide guidance on raising awareness of IDA and approaches for improved diagnosis and treatment of IDA among women in various settings: pregnancy, postpartum, heavy menstrual bleeding, gynecologic cancers, and perioperative care. This clinician-led consensus integrates appropriate recommendations based on clinical evidence and best practices and is intended to guide decision making in the management of iron deficiency/IDA in women. The expert panel raises a call for timely diagnosis and utilization of appropriate treatment, including use of high-dose intravenous iron, stringent blood management, and interdisciplinary collaboration, for optimization of IDA management among women in Asia.

Fermented Goat's Milk Contributes to the Recovery of Iron Deficiency Anemia via Modulation of the Gut Microbiome

Iron deficiency anemia (IDA) is a global public health concern affecting 1.6 billion people worldwide. The administration of iron supplements during the treatment of IDA adversely affects the intestinal barrier function and the composition and functionality of the intestinal microbiome, both of which are already altered during IDA. For this reason, it is of great interest to develop nutritional strategies aimed at alleviating these gut alterations associated with IDA and its treatment. In this sense, fermented goat's milk (FGM) was studied due to its nutritional quality. Our findings showed that in anemic animals the consumption of a FGM-based diet, compared to a standard diet, had positive modulatory effects on the intestinal microbiome. FGM-based diet restored intestinal dysbiosis, the intestinal barrier functionality, and bacterial translocation, contributing to a more efficient recovery of IDA. Therefore, FGM is a useful nutritional tool to ease intestinal alterations occurring during IDA and during its treatment.

Exploring the Impact of Blood Disorders on Dental Caries

Blood comprises various cellular elements and serves as our immune system's second line of defense. Deviations from its normal composition can have adverse effects on health. At the same time, the oral mucosa in the oral cavity functions as the body's first line of defense, and any anomalies or diseases within it can give rise to both systemic and oral complications. If left untreated, caries can lead to severe tooth damage or extraction, potentially affecting an individual's nutrition and overall health. This review article focuses on the importance of understanding the intricate relationship between blood disorders and oral health. It underscores the profound impact of oral manifestations of blood disorders such as β-thalassemia, sickle cell disease, iron deficiency anemia, leukemia, hemophilia, Plummer-Vinson syndrome, erythroblastosis fetalis, Fanconi anemia, cyclic neutropenia, and acute lymphoblastic leukemia on the overall well-being of an individual.

Case report]

Rendu-Osler-Weber disease or hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disease. It is characterized by vascular dysplasia with the formation of telangiectasias on the skin, mucous membranes of the respiratory and digestive tracts, arteriovenous malformations (AVMs) in the internal organs, which is manifested by bleeding. Diagnosis is based on Curacao criteria: recurrent and spontaneous nosebleeds, multiple telangiectases on the characteristic localizations, AVMs in one or more of the internal organs, a family history of HHT (i.e. first-degree relative who meets these same criteria for definite HHT). Therapy is aimed at preventing and stopping gastrointestinal, nosebleeds, correction of iron deficiency anemia. A promising method of therapy is the use of angiogenesis inhibitors, in particular bevacizumab. The article presents a description of a clinical case of HHT in a 49-year-old woman with telangiectisia on the mucous membrane of the tongue, gastrointestinal tract and liver AVMs.

Are Twin Pregnancies at Higher Risk for Iron and Calcium Deficiency than Singleton Pregnancies?

The aim of this study was to compare the iron and calcium status in singleton and twin pregnancies and to assess whether there is an increased risk for iron and calcium deficiency in twin gestation. The study included 105 singleton and 9 twin pregnancies at or above 35 weeks of gestation. Information on prenatal supplementation with iron or calcium was acquired, and adverse perinatal outcomes were recorded. Biosamples from all 114 mothers and 73 newborns (61 singleton and 12 twin newborns) were finally analyzed. Total iron and calcium concentrations in serum were measured through total reflection X-ray fluorescence analysis. The results indicated no significant differences in maternal serum iron and calcium concentrations between singleton and twin pregnancies. Similarly, iron and calcium concentrations in newborn umbilical cord serum samples were not different between singleton and twin pregnancies. The comparison of total iron and calcium between mothers and umbilical cord serum indicated significantly lower concentrations in the mothers, with the differences being not homogenous but rather pair-specific. A significant positive correlation between maternal serum and umbilical cord serum calcium concentration was noticed. Prenatal iron supplementation was associated with higher iron concentrations in both mothers and newborns, supporting the efficiency of supplementation and the quality of the study methods. Collectively, the data indicate no significant differences in serum iron and calcium concentrations with regard to singleton or twin pregnancies and the efficiency of iron supplementation during pregnancy for increasing iron status.

Network pharmacology and molecular docking to explore the mechanism of Sheng Xue Bao mixture against iron deficiency anemia

Based on network pharmacology and molecular docking, we investigated the mechanism of action of Sheng Xue Bao mixture (SXBM) in treating iron deficiency anemia (IDA). We screened the HERB and traditional Chinese medicine systems pharmacology database and analysis platform databases to identify the active ingredients and targets of SXBM. The targets associated with "iron deficiency anemia" were collected from GeneCards, TTD, and OMIM databases. A component-target interaction network was constructed using Cytoscape 3.8.2. The protein-protein interaction network of candidate targets was generated using the STRING database and visualized with Cytoscape 3.8.2 software. Core modules obtained from clustering analysis were subjected to Gene Ontology and Kyoto encyclopedia of genes and genomes enrichment analysis. Finally, molecular docking validation of key targets and active components was performed using Autodock Vina software. A total of 174 active components and 111 genes were identified as potential active components and targets for IDA treatment, including quercetin, kaempferol, luteolin, beta-sitosterol, and other flavonoids as main active components. Gene Ontology enrichment analysis show that interleaved genes are enriched in 2328 biological processes, 71 cellular component expression processes, and 157 molecular function processes. Kyoto encyclopedia of genes and genomes analysis mainly envolved Prostate cancer, Hepatitis B, Kaposi sarcoma-associated herpesvirus infection, Endocrine resistance, Lipid and atherosclerosis, Central carbon metabolism in cancer, Human cytomegalovirus infection and HIF-1 signaling pathway. STAT3, SRC, PIK3R1, and GRB2 were selected as core targets. The molecular docking results demonstrated strong interactions between key components and their respective target proteins. Network pharmacological analysis suggested that SXBM could treat IDA by regulating various biological processes and related signaling pathways. It laid the foundation for further elucidating the molecular mechanism of SXBM treatment of IDA.

Anemia and Associated Risk Factors in Pediatric Patients

Anemia is the most common hematologic abnormality identified in children and represents a major global health problem. A delay in diagnosis and treatment might place patients with anemia at risk for the development of rare but serious complications, including chronic and irreversible cognitive impairment. Identified risk factors contributing to the development of anemia in children include the presence of nutritional deficiencies, environmental factors, chronic comorbidities, and congenital disorders of hemoglobin or red blood cells. Pediatricians, especially those in the primary care setting, serve a particularly critical role in the identification and care of those children affected by anemia. Prompt recognition of these risk factors is crucial for developing appropriate and timely therapeutic interventions and prevention strategies.

Iron Deficiency Anemia Presenting With Pancytopenia: A Study From India

INTRODUCTION

Iron deficiency anemia (IDA) is the most common cause of anemia worldwide. IDA is commonly associated with thrombocytosis and normal or slightly decreased leukocyte count. Sometimes it can present with thrombocytopenia, but rarely present with pancytopenia. Here we are presenting six cases of severe iron deficiency presenting with pancytopenia, which responded to iron replenishment.

METHODS

 This 12-month observational study was conducted in the Department of General Medicine at a tertiary care Centre in India. All cases of pancytopenia (after exclusion of other causes) with IDA were included. IDA was established with the help of a complete blood count (CBC), peripheral smear examination, serum iron studies, and serum ferritin.  Results: In our study, CBC at four weeks later of iron transfusion without other supplementation showed significant improvement in hematological parameters.

CONCLUSION

 Severe iron deficiency is a reversible etiology of pancytopenia. It should be kept as a differential diagnosis of pancytopenia if common causes of pancytopenia are ruled out.

Malignancy-related mir-210, mir-373 and let-7 levels are affected in iron deficiency anemia

Background

Hypoxia is the hallmark of iron deficiency anemia (IDA) and in hypoxic environment, significant changes are observed in malignancy-related microRNAs (miRNA). Our aim is to examine whether there is any difference in the levels of miR-210, miR-373 and let-7, which are directly related to malignancies in patients with IDA.

Methods

Thirty-five female patients with IDA between the ages of 18-65 and 10 healthy controls were included in the study. Patients who received oral iron therapy, who had inflammatory disease, and who were pregnant were excluded from the study. Student t Test was used for comparing variables with normal distribution in two independent groups, and Mann-Whitney U Test was used for variables without normal distribution. Comparison of categorical data was made using the chi-square test.

Results

The mean hemoglobin and ferritin level were 10,78±0,93 and 6.28±5,76 respectively. Plasma miR-210 expression were found as -7.27±2.23 and -6.15±0,88 in IDA and control group respectively (p = 0.022). Plasma miRNA-373 were -7.36±2,58 and -6,96±1,93 and let-7 expression were 2.14±2,15 and 3,57±2,21 in IDA and control group. (p = 0.65 and p = 0.20, respectively).

Conclusions

Plasma miR-210 expression was significantly up-regulated and miR-373 and let-7 expression was down-regulated, though insignificantly, in IDA group.

Comparison of iron isomaltoside ferumoxytol with iron sucrose for iron deficiency anemia: a meta-analysis of randomized controlled trials

Introduction

The efficacy of iron isomaltoside ferumoxytol versus iron sucrose to treat iron deficiency anemia remains controversial. We conduct this meta-analysis to explore the influence of iron isomaltoside ferumoxytol versus iron sucrose on iron deficiency anemia.

Methods

We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through March 2021 for randomized controlled trials (RCTs) assessing the effect of iron isomaltoside ferumoxytol versus iron sucrose on iron deficiency anemia. Meta-analysis was performed using the random-effect model.

Results

Four RCTs involving 3892 patients were included in the meta-analysis. Overall, compared with iron sucrose for iron deficiency anemia, iron isomaltoside showed similar change of Hb (SMD=0.14; 95% CI=-0.07 to 0.35; P=0.18), Hb responder (SMD=1.41; 95% CI=0.71 to 2.81; P=0.33), serum ferritin (SMD=15.13; 95% CI=-23.45 to 53.71; P=0.44), and transferrin saturation (SMD=1.20; 95% CI=-1.08 to 3.47; P=0.30). However, iron isomaltoside further improved serum-ferritin at week 2 than iron sucrose (SMD=204.79; 95% CI=38.23 to 371.35; P=0.02).

Conclusions

Iron isomaltoside ferumoxytol showed comparable efficacy to iron sucrose for the treatment of iron deficiency anemia.

Serum iron levels in tuberculosis patients and household contacts and its association with natural resistance-associated macrophage protein 1 polymorphism and expression

BACKGROUND

Iron deficiency can impair immune function, increasing tuberculosis (TB) susceptibility and severity. The research aimed to investigate iron deficiency anemia in TB patients and household contacts and its association with natural resistance-associated macrophage protein 1 (NRAMP1) polymorphism and expression.

METHODS

The levels of iron, ferritin, and transferrin were measured in the serum by ELISA (Enzyme-Linked Immunosorbent Assay). NRAMP1 polymorphisms were determined by polymerase chain reaction (PCR) and sequencing. NRAMP1 gene expression was measured by real-time PCR. Interferon-gamma release assay (IGRA) checked on household contacts to screen household contacts with positive IGRA as the control.

RESULTS

This study involved 35 TB cases and 35 TB contacts. The results showed that the serum Fe levels were found to be lower in the TB case group (median 149.6 μmol/L) than in the positive IGRA household contacts group (median 628.53 μmol/L) with a p-value <0.001. Meanwhile, ferritin levels in TB cases tended to be higher, in contrast to transferrin, which was found to tend to be lower in TB cases than household contacts but did not show a significant difference. This study found no association between the polymorphism of exon 15 D543 and active TB. However, NRAMP1 gene expression was lower in TB cases than in positive IGRA household contacts (p = 0.011). Besides, there was a positive correlation between NRAMP1 gene expression and serum Fe levels (r = 0.367, p = 0.006). TB was associated with decreased NRAMP1 gene expression (OR 0.086 95% CI 0.02-0.366, p = 0.001). Besides, TB was associated with low Fe levels (OR 0.533 95% CI 0.453-0.629, p < 0.001).

CONCLUSION

Comparing the TB case to the household contacts group, decreased serum Fe levels were discovered in the TB case group. This study also shows a correlation of NRAMP1 gene expression to Fe levels in TB patients and household contacts and describes that TB may lead to decreased Fe levels by downregulating NRAMP1 expression.

What is wrong in doing good?

Hypophosphataemia is a common side-effect in patients with iron deficiency anaemia treated with ferric carboxymaltose, which is not a class effect of all intravenous (IV) iron formulations. The report by Chu et al. shows that moderate and severe hypophosphataemia is common and can even require IV supplementation of phosphate with unknown long-term consequences. Commentary on: Chu et al. Incidence and predictors of hypophosphataemia after ferric carboxymaltose use-a 3-year experience from a single institution in Singapore. Br J Haematol 2023;202:1199-1204.

Patient-Reported Outcomes After Ferric Carboxymaltose Treatment for Iron Deficiency Anemia: A Prospective Observational Study

Background

Iron deficiency anemia (IDA) is a common cause of fatigue and impaired quality of life. The present study aimed to evaluate the impact of intravenous iron supplementation with ferric carboxymaltose (FCM) on fatigue, physical function, and general health among patients with IDA attending routine clinical care.

Methods

This was a prospective, single arm, observational study of adult patients prescribed with intravenous FCM for the treatment of IDA during routine clinical care. We used Patient-Reported Outcomes Measurement Information System (PROMIS) instruments to evaluate fatigue (PROMIS Short Form v1.0 13a [FACIT-Fatigue]), general health status (PROMIS Scale v1.2), and physical function (PROMIS Short Form v2.0 4a) before and at 3 and 6 months after FCM treatment.

Results

A total of 152 patients were enrolled. Mean age was 47.4 ± 16.0 years and 82.2% were female. Mean serum hemoglobin was 10.2 ± 1.4 g/dL at baseline. All patients were treated with at least one FCM dose at baseline, with 77.6% receiving a two-dose treatment course. The mean baseline FACIT-Fatigue score was 61.0 ± 9.0, improving significantly to 50.2 ± 9.5 at 3 months after FCM treatment. A minimum 5-point improvement, pre-defined as clinically meaningful, was seen in the FACIT-Fatigue, PROMIS Global Physical Health, Global Mental Health and PROMIS Physical Function scores for 72.7%, 52.8%, 41.7% and 39.8% of patients at 3 months (p < 0.0001 for each change from baseline), with statistically significant improvement continuing at 6 months. Mean serum hemoglobin was significantly increased at both 3 and 6 months (12.8 g/dL [N = 44] and 12.4 g/dL [N = 54], respectively).

Conclusion

IDA patients attending routine clinical practice reported substantial levels of fatigue and impairments in physical function and global health prior to intravenous iron treatment. Patients experienced significant improvements in fatigue symptoms, physical function, and global health at 3 months after treatment with FCM, which were sustained at 6 months.

Multifocal Abscesses, Necrotizing Fasciitis, Iron Deficiency Anemia, and Hypophosphatemia Induced by Ferric Carboxymaltose Infusions: Report of a Case of Hereditary Hemorrhagic Telangiectasia

Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant vascular dysplasia in which disrupted angiogenesis leads to increased formation of mucocutaneous telangiectasias or major vascular malformations. Iron deficiency anemia and recurrent abscesses are commonly reported in these patients, reinforcing screening and targeted therapies for these conditions. We report a 50-year-old man with HHT affected by repeated episodes of iron deficiency anemia secondary to recurrent epistaxis requiring frequent intravenous iron infusions. He eventually developed hypophosphatemia and hyperphosphaturia secondary to ferric carboxymaltose. He also had a history of recurrent multifocal abscesses, including a severe presentation of necrotizing fasciitis, requiring multiple surgical interventions. Despite the identification of hypogammaglobulinemia, only after consistent dental treatment and antibiotic prophylaxis did the abscesses stop recurring. We highlight the need for careful consideration of all possible complications inherent to the disease itself but also those related to comorbidities or existing treatments.

Prevalence and Impact of Malnutrition in Hospitalizations Among Celiac Diseases: A Nationwide Analysis

BACKGROUND/AIMS

Celiac disease (CD) is a T-cell-mediated gluten sensitivity that results in villous atrophy in the small intestine, leading to chronic malabsorption. Patients with celiac disease are prone to malnutrition. We assessed the impact of malnutrition on in-hospital outcomes in patients with CD.

MATERIALS AND METHODS

Patients with a primary discharge diagnosis of CD between January 2016 and December 2019 were included in the National Inpatient Sample Database. Data were collected on patient demographics, hospital characteristics, the Charlson Comorbidity Index (CCI), and concomitant comorbidities. The association between malnutrition and outcomes, including mortality, deep vein thrombosis (DVT), pulmonary embolism (PE), sepsis, acute kidney injury (AKI), length of stay (LOS), and total hospitalization charges (THC), was analyzed using the multivariate regression model.

RESULTS

A total of 187310 patients with CD were included in the analysis. Patients with CD and malnutrition had a higher risk of mortality (adjusted odds ratio [aOR], 2.08; p<0.001), AKI (aOR=1.18, p=0.003), and DVT (aOR=1.53; p<0.001) compared to patients with CD without malnutrition. No significant difference was noted in the rates of sepsis and PE. Patients with malnutrition also had a prolonged LOS (2.89 days; p<0.001) and higher THC ($22252.18; p<0.001) compared to patients without malnutrition.

DISCUSSION

Patients with CD and malnutrition are at high risk of worse outcomes. Early identification of malnutrition in CD can help prevent morbidity and mortality. Even strict adherence to a gluten-free diet has been associated with malnutrition. Further studies identifying factors associated with malnutrition in CD and the impact of interventions to prevent and treat malnutrition are encouraged.

Heavy menstrual bleeding, iron deficiency, and iron deficiency anemia: Framing the issue

For girls and women in their reproductive years, the symptom of heavy menstrual bleeding (HMB) is the most common cause of iron deficiency (ID), including the extreme manifestation of iron deficiency anemia (IDA). It is recognized that these two clinical entities are not only ubiquitous, but their interrelationship is poorly appreciated and frequently normalized by society, healthcare providers, and affected girls and women themselves. Both HMB and ID/IDA adversely impact quality of life-HMB during the episodes of bleeding and ID daily as long as the ID exists. These combined issues undermine the lives of reproductive-aged girls and women of all ages, from menarche to menopause. At the same time, pervading culture and the often insidious nature of these disorders frequently lead to societal normalization, including by healthcare professionals. The effects on cognitive function as well as the related work and school absenteeism and presenteeism can undermine the efforts and function of women in all walks of life, be they students, educators, employers, or employees. There is also an increasing body of evidence suggesting that ID, even in early pregnancy, may adversely impact fetal neurodevelopment with enduring effects on a spectrum of cognitive and psychological disorders-effects that can have widespread impacts on society. Collectively, this critically important evidence begs the implementation of diagnostic and management guidelines aimed at identifying iron-deficient girls and women, repleting their iron stores, and, when present, effectively treating the most common reason for the problem-the various causes of the symptom of HMB.

Tackling Anemia in Pregnant Women in India: Reviewing the Obstacles and Charting a Path Forward

This study examined the obstacles and factors influencing the prevention and treatment of anemia among pregnant women in India. Maintaining antenatal care is essential, leading to favorable birth outcomes and healthier offspring. However, inadequate consumption of essential nutrients is widespread among pregnant women, particularly in lower and middle-income economies such as India, contributing to high maternal and infant mortality rates. The factors influencing anemia prevention and treatment are categorized into individual, socioeconomic, interpersonal, and organizational levels. This study discussed the prevalence of anemia among pregnant women in different states of India. It highlights the interventions and initiatives the government and World Health Organization (WHO) have implemented to address the issue while also emphasizing the need for comprehensive approaches that effectively address the multiple levels of influence needed to prevent and treat anemia. It calls for increased awareness, improved education, and better healthcare services to ensure proper nutrition and iron supplementation. Strengthening healthcare systems and involving family members and healthcare providers in supporting pregnant women are crucial for successful anemia prevention and treatment programs.

The importance of iron deficiency in pregnancy on fetal, neonatal, and infant neurodevelopmental outcomes

The role of iron in neurodevelopment has long been recognized, and the adverse effects of early-life iron deficiency on brain development and subsequent function across the lifespan continue to be a subject of research. A greater appreciation of the contribution of maternal preconceptional iron status and fetal iron accretion to offspring, postnatal iron status, and brain health across the lifespan has occurred over the past decade. This paradigm shift in thinking links two previously relatively siloed literatures: neonatal iron deficiency and postnatal iron deficiency. The understanding that iron accretion during the fetal period strongly influences postnatal iron balance has led to an appreciation of the importance and value of ensuring proper fetal iron loading. This article reviews the dynamics of fetal iron metabolism, the role of iron in the developing fetal brain, the short- and long-term neurobehavioral consequences of fetal iron underloading, and the potential mechanisms that account for the long-term effects of fetal/neonatal iron deficiency.

Optimizing diagnosis and treatment of iron deficiency and iron deficiency anemia in women and girls of reproductive age: Clinical opinion

Iron deficiency (ID) is the world's most common disorder and one of the top five causes of years lived with disability. Whereas low serum ferritin is diagnostic of ID, ferritin-an acute phase reactant-may be elevated in inflammatory states and the first trimester of pregnancy even if ID exists. Consequently, in early pregnancy or chronic inflammation, percent transferrin saturation (TSAT) measurement is the best indicator of iron status. Unfortunately, current guidelines do not recommend routine screening for ID in either pregnant or nonpregnant women in the absence of anemia. This circumstance should be urgently reviewed based on available data. While oral formulations have long been the standard for iron replacement therapy and are widely available and inexpensive, oral iron is frequently associated with adverse gastrointestinal effects for the majority-a major reason for poor adherence, inadequate repletion, and persisting ID symptoms and sequellae. Although safe intravenous iron administration was introduced in the mid-1950s, formulations with cores binding the elemental iron more tightly became available in the 2000s, allowing complete and safe replacement, even in a single setting. Prospectively acquired neonatology evidence reports oral iron's failure to reach the developing fetus when the mother is iron deficient. Consequently, while oral iron remains frontline in the first trimester because of insufficient safety data for intravenous iron, the author recommends that the intravenous route should be the gold standard for second-trimester ID when hemoglobin concentrations are less than 10.5 g/dL and for all iron-deficient women in their third trimester.

Contemporary evaluation of women and girls with abnormal uterine bleeding: FIGO Systems 1 and 2

Abnormal uterine bleeding (AUB) is common, often debilitating, and may affect over 50% of reproductive-aged women and girls. Whereas AUB is a collection of symptoms that include intermenstrual bleeding and abnormalities in period duration, cycle length, and regularity, it is heavy menstrual bleeding (HMB) that is most contributory to iron deficiency and related anemia. It is apparent that AUB, in general, and HMB, in particular, remain underrecognized and underreported. FIGO created two systems for assessing and classifying AUB. FIGO System 1 defines the bleeding pattern using four primary descriptors: frequency, duration, regularity, and flow volume. FIGO System 2 provides a structured classification system of possible causes of AUB, using the acronym PALM-COEIN. "PALM" refers to structural causes of AUB (Polyp, Adenomyosis, Leiomyoma, Malignancy), and "COEI" refers to nonstructural causes (Coagulopathy, Ovulatory dysfunction, Endometrial, and Iatrogenic). The "N" is reserved for those entities that are currently not otherwise classified. Using FIGO System 1 as a gateway to FIGO System 2 streamlines the investigation of reproductive-aged women and girls with AUB. Understanding the pathogenesis of the FIGO System 2 "PALM-COEIN" causes helps interpret investigations and the onward management of AUB. Numerous evidence gaps exist concerning AUB; however, if researchers and trialists universally adopt FIGO Systems 1 and 2 for the assessment and diagnosis of AUB, clear translatable research findings can be applied globally.

Overview of iron deficiency and iron deficiency anemia in women and girls of reproductive age

Over 50% of pregnant women are anemic and the majority of these are iron deficient. Micronutrient deficiency, the symptom of heavy menstrual bleeding in nonpregnant individuals, and loss of blood associated with pregnancy and obstetric delivery contribute to iron deficiency (ID). Poor outcomes with low maternal iron can affect not only the pregnancy but can also have major bearings on the offspring. Correction of ID and iron deficiency anemia (IDA) in pregnant and prepregnant populations with single-dose intravenous iron supplementation may offer improved outcomes. A harmonization process that incorporates all major randomized controlled trials studying the use of single-dose IV iron compared with oral iron may suggest actions for changing the global trajectory of ID/IDA for women and girls of reproductive age.

Machine Learning Prediction of Iron Deficiency Anemia in Chinese Premenopausal Women 12 Months after Sleeve Gastrectomy

Premenopausal women, who account for more than half of patients for bariatric surgery, are at higher risk of developing postoperative iron deficiency anemia (IDA) than postmenopausal women and men. We aimed at establishing a machine learning model to evaluate the risk of newly onset IDA in premenopausal women 12 months after sleeve gastrectomy (SG). Premenopausal women with complete clinical records and undergoing SG were enrolled in this retrospective study. Newly onset IDA after surgery, the main outcome, was defined according to the age- and gender-specific World Health Organization criteria. A linear support vector machine model was developed to predict the risk of IDA after SG with the top five important features identified during feature selection. Four hundred and seven subjects aged 31.0 (Interquartile range (IQR): 26.0-36.0) years with a median follow-up period of 12 (IQR 7-13) months were analyzed. They were divided into a training set and a validation set with 285 and 122 individuals, respectively. Preoperative ferritin, age, hemoglobin, creatinine, and fasting C-peptide were included. The model showed moderate discrimination in both sets (area under curve 0.858 and 0.799, respectively, p < 0.001). The calibration curve indicated acceptable consistency between observed and predicted results in both sets. Moreover, decision curve analysis showed substantial clinical benefits of the model in both sets. Our machine learning model could accurately predict newly onset IDA in Chinese premenopausal women with obesity 12 months after SG. External validation was required before the model was used in clinical practice.
