RESUMO

Iron is an essential trace element for various cellular proteins and for biological processes in all cells. Severe iron deficiency (ID) impairs haem synthesis, reduces erythropoiesis and causes iron deficiency anaemia (IDA). Iron restriction in anaemia of inflammation is mainly due to retention of iron in macrophages. This condition is known as 'functional iron deficiency'. A review of studies performed in Europe shows that the prevalence of ID and IDA in young children varies by region. It is more common in eastern than western European countries. This overview summarises information on the need for iron supplementation in children, and the current understanding of the regulatory mechanisms of iron homeostasis and ironrestricted erythropoiesis. The causes of anaemia during infection and the usefulness of classical and new indicators to distinguish absolute from functional iron deficiency are discussed.

RESUMO

INTRODUCTION: Iron deficiency anaemia (IDA) is common in patients with heart failure (HF) and is associated with advanced HF and increased mortality. Intravenous iron supplementation increases exercise tolerance, improves quality of life, and decreases symptoms among patients with HF with reduced ejection fraction (HFrEF) and iron deficiency. Despite this, many patients are not screened or treated for IDA. We aimed to increase rates of screening and treatment of IDA among HF patients through the introduction of curated materials to aid HF clinicians with appropriate screening and treatment. METHODS: We conducted a retrospective chart review to identify the baseline number of HFrEF patients screened and treated for IDA at two ambulatory cardiology clinics in Toronto, Ontario. A quality improvement initiative was then introduced, which consisted of education and curated materials to aid clinicians in the screening and treatment of IDA among HFrEF patients. The proportion of patients screened and treated for IDA preintervention and postintervention were compared using χ2 tests of Independence. RESULTS: In the preintervention cohort, 36.3% (n=45) of patients with anaemia were screened for IDA. Among those screened, 64.4% (n=29) had IDA. Only 17.2% (n=5) of these were treated with IV iron. After implementation of the quality improvement initiative, 90.9% (n=60) of patients with anaemia were screened for IDA (p<0.001) and 90.3% (n=28) of those with IDA were treated with IV iron (p<0.001). CONCLUSION: The introduction of curated materials to aid clinicians was associated with increased rates of screening and treatment of IDA among ambulatory HFrEF patients. Further work is required to identify barriers and implement strategies to increase screening and treatment rates of IDA among HFrEF patients.

RESUMO

The association between anemia and outcomes in glioblastoma patients is unclear. We analyzed data from 1346 histologically confirmed adult glioblastoma patients in the TriNetX Research Network. Median hemoglobin and hematocrit levels were quantified for 6 months following diagnosis and used to classify patients as anemic or non-anemic. Associations of anemia and iron supplementation of anemic patients with median overall survival (median-OS) were then studied. Among 1346 glioblastoma patients, 35.9% of male and 40.5% of female patients were classified as anemic using hemoglobin-based WHO guidelines. Among males, anemia was associated with reduced median-OS compared to matched non-anemic males using hemoglobin (HR 1.24; 95% CI 1.00-1.53) or hematocrit-based cutoffs (HR 1.28; 95% CI 1.03-1.59). Among females, anemia was not associated with median-OS using hemoglobin (HR 1.00; 95% CI 0.78-1.27) or hematocrit-based cutoffs (HR: 1.10; 95% CI 0.85-1.41). Iron supplementation of anemic females trended toward increased median-OS (HR 0.61; 95% CI 0.32-1.19) although failing to reach statistical significance whereas no significant association was found in anemic males (HR 0.85; 95% CI 0.41-1.75). Functional transferrin-binding assays confirmed sexually dimorphic binding in resected patient samples indicating underlying differences in iron biology. Anemia among glioblastoma patients exhibits a sex-specific association with survival.

RESUMO

AIMS: Heart failure (HF) patients with anaemia tend to have a worse outcome, with increased hospitalization rates, decreased exercise tolerance, and higher mortality compared to those without anaemia. Limited research exists on the association between selenium deficiency and anaemia specifically in HF patients, despite previous findings of a correlation in different populations. The BIOSTAT-CHF study demonstrated that higher selenium levels in HF patients were associated to a lower risk of anaemia and iron deficiency. This study investigates the relationship between selenoprotein P (SELENOP) concentrations, a major contributor and functional biomarker of selenium transport, and anaemia, Hb levels, and iron status in hospitalized HF patients. METHODS AND RESULTS: SELENOP was analysed in 320 hospitalized HF subjects, with complete data available for 310 subjects. The relationships between continuous SELENOP concentrations and 1) Hb concentrations, 2) anaemia (Hb < 115 g/L (women), <130 g/L (men)), and 3) iron status (as measured by transferrin receptor 1 (TfR1) which increases in iron deficiency) were evaluated using multivariable logistic and linear regression models. Additionally, SELENOP concentrations in the lowest quartile were related to anaemia, haemoglobin, and iron state in multivariable logistic and linear models. The mean age of the study population was 75.0 ± 11.6 years, and 30% were women. Anaemia was present in 133 subjects (42.9%). SELENOP concentrations were positively correlated with haemoglobin concentrations (0.238; P < 0.001) and negatively with TfR1 concentrations (-0.238, P < 0.001). In multivariable regression models, higher SELENOP concentrations were associated with higher Hb concentrations (B = 3.23; P = 0.002) and lower TfR1 concentrations (B = -0.20; P < 0.001). Furthermore, SELENOP deficiency was associated with lower Hb concentrations (B = -7.64: P = 0.001), higher TfR1 concentrations (B = 0.31; P = 0.003), and higher odds of anaemia in HF patients (odds ratio 2.17; 95% confidence interval 1.23-3.82; P = 0.008). CONCLUSIONS: In hospitalized heart failure patients, lower concentrations of SELENOP were associated with higher prevalence of anaemia.

RESUMO

BACKGROUND: Worldwide, iron deficiency anemia is the most prevalent nutritional deficiency disorder and the leading cause of anemia in children, especially in developing countries. When present in early childhood, especially if severe and prolonged, iron deficiency anemia can result in neurodevelopmental and cognitive deficits, which may not always be fully reversible even following the correction of iron deficiency anemia. OBJECTIVE: This article aimed to familiarize physicians with the clinical manifestations, diagnosis, evaluation, prevention, and management of children with iron deficiency anemia. METHODS: A PubMed search was conducted in February 2023 in Clinical Queries using the key term "iron deficiency anemia". The search strategy included all clinical trials (including open trials, non-randomized controlled trials, and randomized controlled trials), observational studies (including case reports and case series), and reviews (including narrative reviews, clinical guidelines, and meta-analyses) published within the past 10 years. Google, UpToDate, and Wikipedia were also searched to enrich the review. Only papers published in the English literature were included in this review. The information retrieved from the search was used in the compilation of the present article. RESULTS: Iron deficiency anemia is most common among children aged nine months to three years and during adolescence. Iron deficiency anemia can result from increased demand for iron, inadequate iron intake, decreased iron absorption (malabsorption), increased blood loss, and rarely, defective plasma iron transport. Most children with mild iron deficiency anemia are asymptomatic. Pallor is the most frequent presenting feature. In mild to moderate iron deficiency anemia, poor appetite, fatigability, lassitude, lethargy, exercise intolerance, irritability, and dizziness may be seen. In severe iron deficiency anemia, tachycardia, shortness of breath, diaphoresis, and poor capillary refilling may occur. When present in early childhood, especially if severe and prolonged, iron deficiency anemia can result in neurodevelopmental and cognitive deficits, which may not always be fully reversible even with the correction of iron deficiency anemia. A low hemoglobin and a peripheral blood film showing hypochromia, microcytosis, and marked anisocytosis, should arouse suspicion of iron deficiency anemia. A low serum ferritin level may confirm the diagnosis. Oral iron therapy is the first-line treatment for iron deficiency anemia. This can be achieved by oral administration of one of the ferrous preparations, which is the most cost-effective medication for the treatment of iron deficiency anemia. The optimal response can be achieved with a dosage of 3 to 6 mg/kg of elemental iron per day. Parenteral iron therapy or red blood cell transfusion is usually not necessary. CONCLUSION: In spite of a decline in prevalence, iron deficiency anemia remains a common cause of anemia in young children and adolescents, especially in developing countries; hence, its prevention is important. Primary prevention can be achieved by supplementary iron or iron fortification of staple foods. The importance of dietary counseling and nutritional education cannot be overemphasized. Secondary prevention involves screening for, diagnosing, and treating iron deficiency anemia. The American Academy of Pediatrics recommends universal laboratory screening for iron deficiency anemia at approximately one year of age for healthy children. Assessment of risk factors associated with iron deficiency anemia should be performed at this time. Selective laboratory screening should be performed at any age when risk factors for iron deficiency anemia have been identified.

RESUMO

Iron-deficiency anemia occurs most commonly in young children due to a low-iron diet and adolescent girls due to menstrual blood loss. However, children with gastrointestinal conditions such as intestinal failure, inflammatory bowel disease, celiac disease, and/or other chronic conditions, including chronic kidney disease and heart failure, also commonly have iron deficiency. Many patients with classic iron-deficiency anemia will improve with oral iron therapy. However, in children who have an incomplete response to oral iron, intravenous iron therapy is increasingly being used. Benefits of intravenous iron therapy include a rapid repletion of iron stores in addition to resolution of anemia, less gastrointestinal side effects, and relief for patients and families struggling with long-term iron supplementation. Indications for first-line therapy with intravenous iron in children with chronic conditions have also increased. Four intravenous iron formulations have approved indications in pediatrics, and many are increasingly used off-label in children as well. Here we discuss the indications and appropriate timing of intravenous iron therapy in children with a wide range of underlying etiologies.

RESUMO

Postpartum hemorrhage (PPH) is responsible for 30% to 50% of maternal deaths. There is conflicting evidence if prepartum anemia facilitates PPH. A comprehensive analysis of studies describing their relation is missing. An extensive database search was conducted applying the terms "anemia" OR "hemoglobin" AND "postpartum hemorrhage." We used a random-effects meta-analysis model to estimate an overall odds ratio (OR) for PPH and prepartum anemia, separating studies that were conformant and non-conformant with the World Health Organization (WHO) definitions for anemia. The search yielded 2519 studies, and 46 were appropriate for analysis. The meta-analyses of WHO-conformant (n = 22) and non-conformant (n = 24) studies showed that the risk of PPH was increased when anemia was present. The ORs were 1.45 (CL: 1.23-1.71) for WHO-conformant studies, 2.88 (CL: 1.38-6.02) for studies applying lower thresholds for anemia, and 3.28 (CL: 2.08-5.19) for undefined anemia thresholds. PPH risk appeared to increase with lower anemia thresholds. Prepartum anemia is associated with an increased risk of PPH, an observation that is important regarding improved anemia correction strategies such as iron supplementation.

RESUMO

Background: Multiple myeloma (MM), a malignant plasma cell proliferative disease, makes up to 1% of all cancers and somewhat exceeds 10% of all hematological cancers. Since it affects many organs, the signs and symptoms of myeloma vary greatly. This investigation was carried out to identify the clinical and laboratory characteristics of MM. Method: From January 1, 2014, to June 30, 2020, 169 in-patients who received a MM diagnosis for the first time at China-Japan Friendship Hospital in Beijing had their medical information examined. Results: Among 169 newly diagnosed patients, the median age was 60 years (26-84 years). Seven patients were younger than 40 years, and 16.0% (27/169) were 70 years or older. 40.8% (69/169) had IgG M-protein and 27.2% (46/169) had IgA. 84% (142/169) of patients were in the Durie Salmon stage 3. The major sign and symptoms at diagnosis were fatigue (100/169, 59.2%), bone pain (96/169, 56.8%), and weight loss (34/169, 20.1%). Anemia was present initially in 94.0% (159/169), high erythrocyte sedimentation rate in 92.7% (101/109), and thrombocytopenia in 26.6% (45/169). Similarly, hypercalcemia, renal insufficiency, and hypoalbuminemia were observed in 19.3% (31/161), 27.8%, and 75.7% respectively. Immunoparesis was found in 94% (110/117) of IgG, IgA, or IgM patients, and in 87% (33/38) of light chain myeloma patients. A localized band was found in 78.3% (123/157) of patients upon serum protein electrophoresis while monoclonal protein was detected by immunofixation in 91.5% (139/152) of patients. 4.1% (7/169) of the patients had non-secretory myeloma. The prevalence of light chain myeloma was 22.5% (38/169), and these individuals were more likely than other myeloma patients to have renal insufficiency (50% versus 21%, P < .05). In 84.8% of patients, the bone marrow had 10% or more plasma cells. Conclusion: The notable features that can be concluded from this study are the early onset of myeloma in the Chinese population and an advanced disease stage at the time of diagnosis with most of them accompanying anemia, hypoalbuminemia, and immunoparesis.

RESUMO

Ulcerative colitis (UC) is often associated with anemia. Hepcidin, the central regulator of iron homeostasis, is known to be induced by inflammation and suppressed by anemia. It is not clear how hepcidin is affected in those with UC, when both inflammation and anemia may co-exist.Such knowledge may hold implications for treatment. Hematological and iron-related parameters, C-reactive protein (CRP), growth differentiation factor 15 (GDF-15) and erythroferrone (ERFE) (erythroid regulators of hepcidin) levels were estimated in blood from those with UC and in control subjects. Values for hematological and iron-related parameters showed evidence of iron-deficiency and resultant anemia, in patients with UC. The presence of UC was significantly associated with inflammation. Serum levels of ERFE, but not of GDF-15, were significantly higher in patients with UC than in control patients, while hepcidin levels were significantly lower. Serum hepcidin concentrations in patients with UC correlated positively with serum iron, ferritin and GDF-15, and negatively with serum ERFE. The iron status and serum hepcidin levels in UC patients with co-existent anemia were significantly lower and serum ERFE values significantly higher than in those with UC without anemia. The effect of anemia on hepcidin predominated over that of inflammation in patients with UC, resulting in suppressed hepcidin levels. This effect is possibly mediated through erythroferrone. We suggest that a serum hepcidin-guided approach may be useful to guide use of oral iron supplements to treat co-existent iron-deficiency anemia in patients with UC and other chronic inflammatory diseases.

RESUMO

OBJECTIVE: Anemia is highly prevalent among people living with HIV (PLWHIV) and is often due to iron deficiency. This study evaluated the relationship of dietary iron intake levels and sources with mortality and clinical outcomes among adults initiating HAART. DESIGN: We conducted a secondary analysis of a multivitamin supplementation trial among 2293 PLWHIV initiating HAART in Dar es Salaam, Tanzania. METHODS: Dietary iron intake was assessed with a food frequency questionnaire at HAART initiation, and participants followed until death or censoring. Total, animal-, and plant-sourced iron were categorized into quartiles. Intake of food groups was categorized into 0-1, 2-3, and ≥4 servings/wk. Cox proportional hazards models estimated hazard ratios for mortality and incident clinical outcomes. RESULTS: There were 175 deaths (8%). Red meat intake was associated with a lower risk of all-cause mortality (HR: 0.54; 95% CI: 0.35 to 0.83), AIDS-related mortality (HR: 0.49; 95% CI: 0.28 to 0.85), and severe anemia (HR: 0.57; 95% CI: 0.35 to 0.91), when intake ≥4 servings/wk, compared with 0-1 servings/wk. Legume intake was a lower risk of associated with all-cause mortality (HR: 0.49; 95% CI: 0.31 to 0.77) and AIDS-related mortality (HR: 0.37; 95% CI: 0.23 to 0.61), when intake ≥4 servings/wk, compared with 0-1 servings/wk. Although total dietary iron and overall plant-sourced iron intake were not associated with the risk of mortality or HIV-related outcomes, the highest quartile of animal-sourced iron intake was associated with a lower risk of all-cause mortality (HR: 0.56; 95% CI: 0.35 to 0.90) and a lower risk of AIDS-related mortality (HR: 0.50; 95% CI: 0.30 to 0.90), compared with the lowest quartile. CONCLUSION: Intake of iron-rich food groups may be associated with a lower risk of mortality and critical HIV-related outcomes among adults initiating HAART. TRIAL REGISTRATION: The parent trial was registered at Clinicaltrials.gov . Identifier: NCT00383669.

RESUMO

BACKGROUND: Collagen gastritis is a rare disease that manifests in children mainly as isolated gastric involvement associated with martial deficiency anemia. There are no recommendations for the management and follow-up of these patients. We aimed to describe the clinical data, endoscopic findings, and treatments deployed in France's children with collagenous gastritis. METHODS: All French pediatric gastroenterology centers and pediatric centers for rare digestive diseases (Centres de Maladies Rares Digestives) were contacted to collect cases of collagenous gastritis, defined on gastric biopsies and diagnosed before 18 years of age. RESULTS: A total of 12 cases diagnosed (4 males and 8 females) between 1995 and 2022 could be analyzed. The median age at diagnosis was 12.5 years (7-15.2). The most frequent clinical presentation was abdominal pain (6/11) and/or nonspecific symptomatology attributed to anemia (8/10). Anemia was present in all children (11/11; Hb 2.8-9.1 g/dL). Nodular gastritis was present in 10 patients (antrum: 2; fundus: 4; in antrum and fundus: 4). All patients had a basement membrane thickening (from 19 to 100 µm). The treatments received were PPI (11), oral or intravenous martial supplementation (12), budesonide (1), and prednisone (1). Martial supplementation improved anemia in all cases. At discontinuation, nine of 10 patients had a recurrence of anemia. CONCLUSION: Collagenous gastritis is an exceptional condition, clinically manifested in children as abdominal pain and iron deficiency anemia probably of hemorrhagic origin. Patients require long-term follow-up and monitoring of their disease to describe the risk of progression better.

RESUMO

INTRODUCTION: Prevalence of vitamin B12 deficiency is occasionally found to be coexisting in patients with hypothyroidism causing persistence of symptoms concomitant to both diseases even on adequate thyroxine supplementation. MATERIALS: A single-centric non-interventional cross sectional study was carried over a period of 1 year. 100 hypothyroid patients were evaluated for prevalence of anemia, and investigated for the etiology. Serum Vitamin B12 was obtained and an association was studied between Vitamin B12 and anti TPO and anti Thyroglobulin antibodies. Here, vitamin B12 deficiency was defined as <160 pg/mL. RESULT: Among 100 hypothyroid patients, 31% were males and 69% were females. The mean age of patients was 36.09±12.864 years. 68% patients were found to be Vitamin B12 deficient, and 73.5% of this deficient population were females. 78.6% patients with raised Anti TPO antibodies had vitamin B12 deficiency (p-value = 0.01), while 78% patients with raised Anti Thyroglobulin antibodies were vitamin B12 deficient (p-value = 0.07). The Pearson correlation coefficient (r) was -0.302 (p = 0.002) and -0.253 (p = 0.011) between Vitamin B12 anti anti TPO and anti Thyroglobulin antibodies respectively, thus showing a negative correlation between both. CONCLUSION: Thyroid hormones affect erythropoiesis, thus causing anemia in a deficient condition. In iodine sufficient areas, most common cause of hypothyroidism is autoimmune, predisposing individuals to other autoimmune diseases, one being pernicious anemia. In the studied anemic hypothyroid population, Vitamin B12 deficiency was found correlated with raised levels of serum anti-TPO and anti-Thyroglobulin antibodies. Supplementation of B12 may alleviate hypothyroid symptoms, thus making itself a novel addition in the routine hypothyroid prescription. References Aon M, Taha S, Mahfouz K, et al.

RESUMO

INTRODUCTION: Scurvy is a deadly disease caused by a lack of vitamin C in the diet. Although frequently considered a disease from the past, it still occurs in modern-day society, including in developed countries. CASE REPORT: We report a case of an 18-year-old male who was admitted with bleeding into his legs, prolonged prothrombin time and partial thromboplastin time, and anemia requiring a blood transfusion. His history included congenital deafness and a restrictive eating pattern primarily consisting of fast food. He was deficient in folic acid, vitamin K, and vitamin C. Scurvy best explained the bleeding, and he improved with vitamin supplementation. DISCUSSION: Scurvy is a collagen production disorder that can cause bleeding on the skin and mucous membranes. Although rare in industrialized nations, scurvy is typically the result of a restrictive diet or malnutrition. Those who are at a particularly high risk are the elderly, alcohol abusers, and those with eating disorders. CONCLUSIONS: Scurvy is easily treatable but can be missed; therefore, a high level of suspicion should be present in patients at risk for malnutrition. Those diagnosed with scurvy should be screened for concomitant nutritional deficiencies.

RESUMO

This study aimed to investigate the prevalence of anemia and related nutrient deficiencies after sleeve gastrectomy (SG). Four online databases were searched for relevant articles. Thirty-one studies with 7639 patients were included in the meta-analysis. The pooled anemia prevalence was 7%, 6%, 9%, 10%, 12%, 25%, 20%, and 18% at baseline, 3 months, 6 months, 12 months, 24 months, 36 months, 48 months, and 60 months, respectively. Although the prevalence of vitamin B12 and folate deficiencies remained low postoperatively, the prevalence of ferritin deficiency steadily increased from 6% at baseline to 27% at 60 months. The prevalence of serum iron deficiency decreased from 13% at baseline to 6% at 24 months and increased to 20% at 60 months. Anemia and ferritin deficiency were strongly correlated (Pearson correlation coefficient = 0.774, p = 0.041). Subgroup analysis suggested that age ≤40 years, preoperative anemia, and insufficient iron supplementations were high-risk factors for postoperative anemia. SG is associated with an increased risk of anemia and decreased iron storage over long-term observation. Routine iron supplementations may reduce anemia after SG; however, the dosages recommended by current guidelines may be insufficient. More strict monitoring schedules and supplementation strategies should be established for the timely detection and management of postoperative anemia.

RESUMO

Iron deficiency anemia in pregnancy is a major public health problem known to cause maternal morbidity and adverse birth outcomes, and it may also have lasting consequences on infant development. However, the impact of the maternal hematological environment on fetal and infant hemoglobin and iron stores in the first year of life remains unclear. This review of the epidemiological evidence found that severe maternal iron deficiency anemia in pregnancy is associated with lower ferritin, and to a lesser degree hemoglobin levels, in infants at birth. Emerging data also suggests that severe anemia in pregnancy increases the risk of iron deficiency and anemia in infants 6-12 months of age, although longitudinal studies are limited. Effective anemia prevention in pregnancy, such as iron supplementation, could reduce the risk of infant anemia and iron deficiency during the first year of life; however, more evidence is needed to determine the functional impact of iron supplementation in pregnancy on infant hematological indices.

RESUMO

BACKGROUND: Maternal anemia is an ongoing public health challenge in low- and middle- income countries, including Bangladesh. The aim of this study was to explore the association of maternal anemia with a range of adverse maternal health and birth outcomes in Bangladesh. METHODS: A total of 2,259 maternal women data was analyzed, extracted from the 2011 Bangladesh Demographic and Health Survey. Outcome variables considered were a range of maternal health and birth outcomes. Adverse maternal health outcomes were pregnancy complications, pregnancy termination, menstrual irregularities, cesarean delivery, diabetes, and hypertension. Adverse birth outcomes considered were low birth weight, stillbirths, early neonatal deaths, perinatal deaths, preterm birth, and prolonged labor. The main exposure variable was maternal anemia status. Mixed effect multilevel logistic/poisson regression model was used to determine the association between exposure and outcome variable adjusted for individual-, household-, and community-level factors. RESULTS: The reported prevalence of anemia was 44%. A higher likelihoods pregnancy complication (AOR, 1.39, 95% CI, 1.09-2.41, p<0.05) and lower likelihoods of menstrual irregularities (AOR, 0.79, 95% CI, 0.58-0.94, p<0.05), diabetes (AOR, 0.78, 95% CI, 0.49-0.98, p<0.05) and hypertensive (AOR, 0.79, 95% CI, 0.60-0.96, p<0.05) were found among anemic maternal women as compared to the non-anemic maternal women. Adverse birth outcomes, including preterm birth (AOR, 2.03, 95% CI, 1.01-4.25, p<0.05), early neonatal mortality (AOR, 1.87, 95% CI, 1.06-5.10), and perinatal mortality (AOR, 1.54, 95% CI, 1.09-3.52, p<0.05), were also found higher among newborn of anemic maternal women as compared to the newborn of non-anemic maternal women. CONCLUSION: Anemia during pregnancy increases the occurrence of adverse maternal health and birth outcomes. Strategies to reduce anemia, such as iron supplementation, during pregnancy and among reproductive-aged women need to be prioritized in the policies and programs.

RESUMO

BACKGROUND: Iron deficiency during infancy is associated with poor neurological development, but iron overload causes severe complications. Appropriate iron supplementation is therefore vital. Reticulocyte hemoglobin content (RET-He) provides a real-time assessment of iron status and chracterezes hemoglobin synthesis in preterm infants. However, the existing literature lacks detailed reports assessing chronological changes in RET-He. The aim of this study was to assess the chronological changes in RET-He during oral iron dietary supplementation, and concomitant therapy with recombinant human erythropoietin (rHuEPO) in preterm very low birthweight infants. METHODS: Very low birthweight infants, admitted to our neonatal intensive care unit were analyzed retrospectively. Hemoglobin (Hb), reticulocyte percentage (Ret), mean corpuscular volume, RET-He, serum iron (Fe), and serum ferritin were recorded. Data at birth (T0), the initial day of rHuEPO therapy (T1), the initial day of oral iron supplementation (T2), 1-2 weeks (T3), 3-4 weeks (T4), 5-6 weeks (T5), and 7-8 weeks (T6) from the initial day of oral iron supplementation were extracted, and their changes over time were examined. RESULTS: Reticulocyte hemoglobin content was highest at birth and declined rapidly thereafter, especially after starting rHuEPO therapy. There was no upward trend in RET-He after the initiation of oral iron supplementation, with a slower increase during 5-6 weeks after the initiation of iron therapy. CONCLUSIONS: During the treatment of anemia of prematurity, low RET-He levels may be prolonged. Anemia of prematurity should therefore be assessed and treated on a case-by-case basis, while considering the iron metabolic capacity of preterm infants.

RESUMO

Iron deficiency anaemia is known to be one of the most common disorders that are associated with malnutrition. This study was conducted to form an understanding of the prevalence of Iron deficiency Anaemia (IDA) and evaluate its risk factors among the residents of the northern Asir Region, Saudi Arabia. Understanding the prevalence of IDA in different populations is important not only for therapeutic purposes but also for preventing the development of IDA in a given community. Moreover, this study was conducted to raise awareness about the significance of following iron-rich diet among high-risk groups such as women and children. This study collected data from 683 anaemic patients who are enrolled at the haematology unit in the Department of Internal Medicine at King Abdullah Hospital, Bisha Saudi Arabia. 398 participants who have IDA were included in this study where the collected data from the subjects included Age, gender, education, marital status, nationality, consanguinity, dietary habits and the clinical presentation of the participants. Our findings have shown that the prevalence of IDA among the participants is 58.27% where children under the age of 10 and females are the most affected individuals. Adults over 40, unmarried, and non-Saudis represented the second most affected portion of the subjects. IDA was prevalent among participants who shared the same ancestors and individuals with limited education. Moreover, participants did not consume sufficient iron and iron enhancing food or supplements. Inadequate iron intake is a major risk factor for anaemia. Low red fish and meat consumption contributed to the increase in ID. Findings highlight the need to raise awareness about the importance of a balanced diet and regular consumption of iron-containing food.

RESUMO

BACKGROUND: Existing studies have reported the significant association between atrophic glossitis (AG) and hematinic deficiencies, including iron, folate and vitamin B12 deficiency. However, these findings were inconsistent. AG can be graded as partial or complete atrophy. It is still unclear whether hematinic deficiencies are associated with the grading of AG. METHODS: 236 AG patients and 208 sex- and age-matched healthy controls were enrolled in this study. Hematological tests including complete blood count, and serum levels of folate, ferritin and vitamin B12 were performed. The AG group was divided into those with partial AG and those with complete AG according to the extent of papillary atrophy. Statistical analysis was performed to assess whether hematinic deficiencies are risk factors for AG and its grading. RESULTS: Compared with the healthy controls, AG patients had significantly higher frequencies of vitamin B12 deficiency (68.22%), ferritin deficiency (13.98%) and anemia (21.61%). The differences in hematinic deficiencies and anemia between AG patients and healthy controls changed according to gender and age. The frequencies of serum vitamin B12 deficiency and anemia in the complete AG subgroup were significantly higher than those in the partial AG subgroup. Logistic regression analysis revealed that vitamin B12 deficiency and anemia were significantly correlated with AG and its grading. The AG patients with vitamin B12 deficiency responded well to supplement therapy. CONCLUSION: AG could be an important clinical indicator for potential vitamin B12 deficiency, especially when the degree of tongue atrophy more than 50% and complete atrophy. Vitamin B12 deficiency might play an etiological role in the development of AG.

RESUMO

(1) Background: Chronic Kidney Disease (CKD) induces metabolic derangement of amino acid (AA) kinetics, eliciting severe damage to the protein anabolism. This damage is further intensified by a significant loss of AAs through hemodialysis (HD), affecting all tissues with a high metabolic turnover, such as the myocardium and body muscle mass. (2) Aim: to illustrate the effects of a novel AA mixture in boosting mitochondrial energy production. (3) Methods: A strict selection of 164 dialysis patients was carried out, allowing us to finally identify 22 compliant patients who had not used any form of supplements over the previous year. The study design envisaged a 6-month randomized, double-blind trial for the comparison of two groups of hemodialysis patients: eleven patients (67.2 ± 9.5 years) received the novel AA mix (TRG), whilst the other eleven (68.2 ± 10.5 years) were given a placebo mix that was indistinguishable from the treatment mix (PLG). (4) Results: Despite the 6-month observation period, the following were observed: maintenance of target hemoglobin values with a reduced need for erythropoiesis-stimulating agents in TRG > 36% compared to PLG (p < 0.02), improved phase angle (PhA) accompanied by an increase in muscle mass solely in the TRG group (p < 0.05), improved Left Ventricular Ejection Fraction (LVEF > 67%) in the TRG versus PLG group (p < 0.05) with early but marked signs of improved diastolic function. Increased sensitivity to insulin with greater control of glycemic levels in TRG versus PLG (p = 0.016). (5) Conclusions: the new AA mix seemed to be effective, showing a positive result on nutritional metabolism and cardiac performance, stable hemoglobin levels with the need for lower doses of erythropoietin (EPO), insulin increased cell sensitivity, better muscle metabolism with less loss of mass.
