Experiencia de uso de hierro intravenoso para el tratamiento de la anemia en niños y adolescentes. Respuesta terapéutica y evolución

Introducción: El hierro de administración intravenosa (iv) está indicado en los casos en que el tratamiento oral no es posible. El objetivo de este trabajo fue describir el perfil de uso, respuesta terapéutica y seguridad de la administración de hierro iv en el tratamiento de la anemia ferropénica en niños, niñas y adolescentes (NNA) asistidos en un centro de referencia de Uruguay entre 2018 y 2023. Método: Estudio retrospectivo mediante revisión de historias. Incluyó todos los NNA que recibieron hierro iv. Se registraron variables sociodemográficas, comorbilidades, clínica y severidad de la anemia. Se evaluó: motivos de la indicación y tipo de hierro iv, dosis, tiempo de infusión, respuesta terapéutica y efectos adversos. Resultados: Se incluyeron 35 pacientes, mediana de edad 4 años; 51,4% de sexo masculino, con comorbilidades 37,1%. Todos los menores de 3 años presentaban factores de riesgo para anemia ferropénica, la falta de adherencia al hierro oral se asoció con mayor severidad de la anemia (p<0,05). El motivo principal de indicación de hierro iv fue la severidad de la anemia e inadecuada respuesta al hierro oral concomitante en 37,1%. Todos recibieron hierro sacarato; mediana de dosis: 2 mg/kg y de tiempo de infusión: 1 hora. Se registró un caso de edema y exantema de cara vinculado a la rápida infusión. La evolución fue satisfactoria. Conclusiones: La administración de hierro iv fue segura. Es necesario establecer consensos respecto a la posología y monitorización. Se requieren nuevos estudios para continuar evaluando la eficacia y seguridad del hierro iv en sus diversas formulaciones.

Introduction: Intravenous (IV) iron administration it is indicated in cases where oral treatment is impossible. The objective of this work was to describe the profile of use, therapeutic response, and safety of the iron IV administration in treating anemia in children and adolescents (NNA) assisted in a reference center in Uruguay between 2018 and 2023. Method: Retrospective study through review of histories. It included all children and adolescents who received IV iron. Sociodemographic variables, comorbidities, clinical symptoms, and severity of anemia they were recorded. They were evaluated: reasons for the indication and type of IV iron, dose, infusion time, therapeutic response, and adverse effects. Results: we included 35 patients, with a median age of four years; 51.4% were male, and 37.1% had comorbidities. All children under three years of age had risk factors for iron deficiency anemia; greater severity of anemia was associated with lack of adherence to oral iron (p<0.05). The main reason for the indication of IV iron was the severity of anemia and inadequate response to concomitant oral iron at 37.1%. All received iron saccharate; median dose: 2 mg/kg and infusion time: 1 hour. A case of facial edema and rash linked to rapid infusion was recorded. The evolution was satisfactory. Conclusions: The administration of IV iron was safe. It is necessary to establish a consensus regarding dosage and monitoring. New studies are required to continue evaluating the efficacy and safety of IV iron in its various formulations.

Granuloma piogénico oral de comportamiento agresivo: Reporte de un caso

El granuloma piogénico es una lesión vascular reactiva benigna del tejido blando que surge en respuesta a irritantes crónicos de bajo grado. Rara vez crece más de 2 cm de diámetro y por lo general, no provoca cambios en el hueso alveolar. Presentamos un caso inusual de granuloma piógeno en una mujer de 19 años, de extenso tamaño y comportamiento agresivo, asociado a resorción ósea severa, movilidad dentaria, hemorragia, anemia ferropénica y recurrencias.

Pyogenic granuloma is a benign reactive vascular lesion of the soft tissue that arises in response to chronic low-grade irritants. It rarely grows more than 2 cm in diameter and usually does not cause changes in the alveolar bone. We present the case of a 19-year-old woman with an unusual pyogenic granuloma of extensive size and aggressive behavior, associated with severe bone resorption, tooth mobility, hemorrhage, iron deficiency anemia and recurrences.

Deficiencia de hierro en enfermedad renal crónica

Contexto: la deficiencia de hierro es un trastorno frecuentemente observado en pacientes con enfermedad renal crónica (ERC), sobre todo en estadios avanzados. Su presencia se asocia a una mayor morbilidad y mortalidad. La deficiencia de hierro puede ser absoluta o funcional. La deficiencia absoluta se refiere a una ausencia o una reducción de las reservas de hierro, mientras que la deficiencia funcional se define por la presencia de depósitos de hierro adecuados pero con una disponibilidad insuficiente de hierro para su incorporación en los precursores eritroides. Varios factores de riesgo contribuyen a la deficiencia absoluta y funcional de hierro en ERC, incluyendo pérdidas hemáticas, absorción alterada de hierro e inflamación crónica. Objetivo: con esta revisión narrativa se pretende presentar las definiciones, los aspectos fisiopatológicos, los criterios diagnósticos y las medidas terapéuticas en el paciente con diagnóstico de ERC con deficiencia de hierro. Metodología: se realizó una revisión no sistemática de la literatura en la base de datos PubMed, incluyendo además las guías internacionales más utilizadas que abordan el tema de deficiencia de hierro en ERC. Resultados: se incluyeron un total de 30 referencias bibliográficas. La deficiencia de hierro puede ser absoluta o relativa y el déficit absoluto de hierro se produce con valores de ferritina 100 mcg/l, pero con una TSAT < 20 %. El tratamiento del déficit absoluto consta de reposición de hierro oral o endovenoso y en pacientes que aún no reciben diálisis, se puede hacer una prueba terapéutica con hierro oral, de no haber respuesta se optará por hierro endovenoso, mientras que en pacientes que sí reciben diálisis, la medida ideal es el hierro endovenoso, preferiblemente en preparaciones que permitan esquemas de altas dosis y bajas frecuencias de administración. Las metas propuestas por las distintas guías presentan variaciones entre 500 y 700 mcg/l de ferritina. Conclusiones: el déficit de hierro debe buscarse activamente en pacientes con ERC, ya que su presencia y la falta de intervención conlleva a un incremento en los desenlaces adversos. La terapia con hierro es el pilar del tratamiento y la elección del agente a utilizar dependerá de las características individuales del paciente y de la disponibilidad de las preparaciones de hierro oral o endovenoso.

Background: Iron deficiency is a disorder frequently observed in patients with chronic kidney disease (CKD), especially in advanced stages. Its presence is associated with increased morbidity and mortality. Iron deficiency can be absolute or functional. Absolute deficiency refers to absent or reduced iron stores, while functional deficiency is defined by the presence of adequate iron stores but insufficient iron availability for incorporation into erythroid precursors. Several risk factors contribute to absolute and functional iron deficiency in CKD, including blood fi, impaired iron absorption, and chronic inflammation. Purpose: With this narrative review, it is intended to present the details, pathophysiological aspects, diagnostic criteria and therapeutic options in patients diagnosed with chronic kidney disease with iron deficiency. Methodology: A non-systematic review of the fi ron ra was carried out, in the PubMed database, also including the most used international guidelines that address the issue fi ron deficiency in chronic kidney disease. Results: A total of 30 bibliographical references were included. Iron deficiency can be absolute or relative. The absolute iron deficiency occurs with ferritin values 100 mcg/l but with a TSAT <20 % Treatment of absolute deficiency consists of oral or intravenous iron replacement. In a patient who is not yet receiving dialysis, a therapeutic trial with oral iron can be done, if there is no response, intravenous iron will be chosen. In patients receiving dialysis, the ideal measure is intravenous iron, preferably in preparations that allow high-dose schemes and low frequencies of administration. The goals proposed by the different guidelines present variations between 500 and 700 mcg/l d ferritin. Conclusions: iron deficiency should be actively sought in patients with CKD, since its presence and lack of intervention leads to an increase in adverse outcomes. Iron therapy is the mainstay of treatment; the choice of the agent to be used depends on the individual characteristics of the patient and the availability of oral or intravenous iron preparations.

Anemia por uncinarias, una infección subestimada por el clínico / Hookworm anemia, an infection underestimated by clinician

La uncinariasis fue descrita por primera vez por Dubini en 1838. Es una helmintiasis intestinal causada por el Necator americanus y/o Ancylostoma duodenale. Frecuentemente son endémicas de áreas tropicales y subtropicales; afecta tanto a niños como a adultos. La transmisión asciende cuando existen entornos socioculturales y demográficos que favorecen la contaminación fecal, por lo que es considerado un problema de salud pública en el mundo. Se presenta el caso de un paciente masculino de 20 años que acudió a urgencias por astenia, adinamia, taquicardia y palidez mucocutánea generalizada; el hemograma reportó anemia severa y eosinofilia. Se requirió transfusión de 4 UI de glóbulos rojos y sulfato ferroso. El examen coprológico mostró infección por Necator americanus, que fue tratada con albendazol y, posteriormente, fue egresado de la institución sanitaria. La infección por uncinarias constituye una causa olvidada para el clínico de hemorragia de las vías digestivas y desarrollo de anemia. Por tanto, el presente estudio destaca que esta parasitosis es una causa importante en el diagnóstico diferencial. Además, se ofrece mayor importancia a las estrategias preventivas como la capacitación a profesionales de salud, el refuerzo de técnicas de aseo, la disminución de la contaminación y el aumento de la higiene personal(AU)

Hookworm infection was first described by Dubini in 1838. It is an intestinal helminth infection caused by Necator americanus and/or Ancylostoma duodenale. They are frequently endemic to tropical and subtropical areas and affect both children and adults. Transmission increases when there are socio-cultural and demographic environments that favor fecal contamination; therefore, it is a public health problem worldwide. We describe the case of a 20-year-old male patient who presented to the emergency department with asthenia, adynamia, tachycardia, and generalized mucocutaneous pallor. The blood test showed severe anemia and eosinophilia. Transfusion of 4 IU of red blood cells and ferrous sulphate was required. The coprological test showed infection by Necator americanus, which was treated with albendazole. Afterwards, the patient was discharged from the health institution. Hookworm infection is a neglected cause of gastrointestinal bleeding and anemia by the clinician. Therefore, the present study highlights this parasitosis as an important cause in the differential diagnosis. In addition, greater importance is given to preventive strategies such as training the health professionals, reinforcement of hygiene techniques, decrease of contamination and increase of proper personal hygiene(AU)

Cost-effectiveness analysis of ferric carboxymaltose for treating iron deficiency anemia in adult Chinese patients / 中国药房

OBJECTIVE To evaluate the cost-effectiveness of Ferric carboxymaltose injection in the treatment of iron deficiency anemia in adult Chinese patients. METHODS From the perspective of China’s health system， the partitioned survival model was constructed to simulate the treatment process and outcome of patients with iron deficiency anemia using ferric carboxymaltose and iron sucrose based on the ferric carboxymaltose phase Ⅲ clinical trial in China （NCT03591406）. The study period was 1 year. Total costs and quality-adjusted life years （QALYs） were calculated for both treatment regimens， and incremental cost-effectiveness ratios were calculated. Scenario analysis was performed with different assumptions for efficacy parameters between 9th week and the end of 1 year， and from the perspective of China’s health system and the entire society. The sensitivity analysis was also performed. RESULTS In the basic analysis， compared with iron sucrose， incremental effectiveness of ferric carboxymaltose therapy was 0.007 QALYs， with an additional savings of 1 038 yuan per patient. Ferric carboxymaltose therapy was more effective and less costly， presenting an absolute advantage. The results of the scenario analysis and single-factor sensitivity analysis were consistent with the basic analysis. Probability sensitivity analysis showed that when the willingness-to-pay threshold was 1， 2， 3 times gross domestic product per capita in 2022， the probability of ferric carboxymaltose with a cost- effectiveness advantage was 88.2%，94.5% and 97.6%，respectively. CONCLUSIONS For Chinese adults with iron deficiency anemia， ferric carboxymaltose is a cost-effective treatment for iron deficiency anemia， compared with iron sucrose.

Diagnosis and treatment strategies for patients with refractory recurrent aphthous ulcer and systemic diseases / 口腔疾病防治

@#Recurrent aphthous ulcer (RAU) is one of the most common diseases of the oral mucosa. At present, no effective method is available for RAU treatment, especially for refractory RAU, which significantly affects patients’ oral health and quality of life. Research shows that combination with systemic diseases greatly increases the difficulty of curing refractory RAU, making conventional oral ulcer treatment harder to perform effectively. This is probably because dentists commonly only focus on handling oral ulcers but neglect to think about the etiology of oral ulcers from a holistic perspective. Thus, we summarized some conditions of refractory RAU accompanied by systemic diseases, including inflammatory bowel disease, iron deficiency anemia, diabetes mellitus, Behçet’s disease, Reiter’s syndrome, sprue syndrome, Sutton syndrome, and acquired immunodeficiency syndrome. We also outlined the treatment principles of these patients. To be specific, on the one hand, dentists should cooperate with the relevant specialists to treat the systemic diseases, while on the other hand they should take measures including topical/general use of medicine, local physical therapy, Traditional Chinese medicine treatment, and psychotherapy for RAU management. This paper aims to provide clinicians with a more comprehensive understanding of the diagnosis and treatment of refractory RAU, in order to make personalized treatment plans for patients and improve the clinical efficacy of refractory RAU.

Causes of Abnormal Hemoglobin Electrophoresis / 中国实验血液学杂志

OBJECTIVE@#To investigate the possible causes of abnormal hemoglobin electrophoresis results.@*METHODS@#The hemoglobin electrophoresis results of 5 696 patients in the First Affiliated Hospital of Chengdu Medical College from September 2018 to July 2021 were collected, and the abnormal results and clinical significance were analyzed.@*RESULTS@#The results of 486 patients (accounting for 8.53%) were abnormal, of which 300 cases had increased HbA2, 135 cases had decreased HbA2, 44 cases had increased F alone, and 7 cases had abnormal hemoglobin bands. Among the 486 patients, 246 patients were thalassemia gene positive (the positive rate was 50.62%), including 29 cases of α thalassemia, 208 cases of β thalassemia and 9 cases of αβ thalassemia. Among the patients with elevated HbA2, 68.67% were detected β thalassemia, 3.00% αβ thalassemia, 9.33% were suspected to be caused by macrocytosis, 6.33% by thyroid dysfunction, and 12.67% by uncertainty of the method. Among the patients with reduced HbA2, 21.48% were detected α thalassemia, 60.00% iron deficiency anemia, 8.15% were suspected to be caused by thyroid dysfunction, and 10.37% by uncertainty of the method. Among the patients with elevated F alone, the results of thalassemia gene detection were negative, 40.91% of them were suspected to be caused by macrocytosis, 27.27% by hereditary persistence of fetal hemoglobin, 29.55% by special physiological condition of pregnant women, and 2.27% by hyperthyroidism. Abnormal hemoglobin bands were detected in 7 patients, including 4 cases of hemoglobin D, 2 cases of hemoglobin E, and 1 case of hemoglobin J.@*CONCLUSION@#Thalassemia, iron deficiency anemia, macrocytosis such as megaloblastic anemia and non-severe aplastic anemia, thyroid dysfunction, hereditary persistence of fetal hemoglobin, abnormal hemoglobin diseases, the uncertainty of the method are all important causes of abnormal hemoglobin electrophoresis results. In clinical work, the patient's indicators should be comprehensively analyzed to determine the possible cause.

De la clorosis a la anemia por deficiencia de hierro. La evolución histórica de una enfermedad / From Chlorosis to Iron Deficiency Anemia. The Historical Eevolution of a Disease

Resumen La clorosis fue una enfermedad muy frecuente en la literatura médica de los siglos XVI hasta el inicio del siglo XX; por más de cuatro siglos esta enfermedad también conocida como la "enfermedad verde" (green sickness) o "enfermedad de las vírgenes" (morbus virgineus) ocupó un lugar preponderante en la consulta médica y llegó a alcanzar proporciones "epidémicas" en los siglos XVIII y XIX. Era la hemopatía más frecuente en este siglo, trascendiendo al propio campo de la medicina, con implicaciones sociales importantes, con influencia en la pintura y la literatura europea de esos años. Durante varios siglos no existió acuerdo respecto a su etiología, y hubo que esperar al desarrollo de la hematología, para llegar a ser considerada como una anemia microcítica-hipocrómica, patología frecuente en mujeres jóvenes. Cuando el misterio de su etiología quedó aclarado, sucedió un nuevo "misterio": su desaparición súbita de la nosología y literatura médicas en las primeras décadas del siglo pasado. En el presente trabajo revisamos la evolución histórica de una enfermedad y la construcción social de un concepto de enfermedad.

Abastract Chlorosis was a very frequent disease in medical literature from the 16th century to the beginning of the 20th century; For more than four centuries, this disease, also known as "green sickness" or "virgin disease" (morbus virgineus), occupied a predominant place in medical consultation and reached "epidemic" proportions in the eighteenth century and XIX (it was the most frequent blood disease in this century), transcending the field of medicine itself, with important social implications and influence on European painting and literature of those years. For several centuries there was no agreement regarding its etiology, and it was not until the development of hematology that it was considered a frequent microcytic-hypochromic anemia in young women. When the mystery of its etiology was clarified, a new "mystery" occurred: its sudden disappearance from medical nosology and literature in the first decades of the last century. In this paper we review the historical evolution of a disease and the social construction of a concept of disease.

Risk factors associated with iron deficiency anemia in children under 5 years of age attending a health center in chachapoyas, Peru / Fatores de risco associados à anemia por deficiência de ferro em crianças menores de 5 anos de idade que freqüentam um centro de saúde em Chachapoyas, Peru

Study Design: Retrospective case-control study. Objective: Identify risk factors among sociodemographic, nutritional, and health characteristics associated with iron deficiency anemia in children under five years of age attending the growth and development clinic of the Nueve de Enero de Chachapoyas Health Center in 2019. Methods: Two groups were formed, each consisting of 50 children. Group 1 (G1, cases) were children diagnosed with iron deficiency anemia and a control group (CG) of age-matched healthy children residing in the same jurisdiction. Data were collected from the medical records of the health center in a structured record card based on the study variables: age, birth weight, parasitic diseases, or associated symptomatologies such as diarrhea, frequency, and type of feeding before and after six months of age. Data were grouped in contingency tables to calculate Odds Ratio (OR), and statistical significance was estimated by analysis of variance (ANOVA) with 95% confidence. Results: All the factors considered presented significant association p<0.05, except for sex, concerning the presence of anemia in children. With OR values of: under 32 months of age (OR=2.26, 95% CI 0.59-2.79), under 2900 g birth weight (OR=2.98, 95% CI 0.43-2.99), prolonged exclusive breastfeeding (OR=3.14, 95% CI 1. 55-3.88), early ablactation (OR=4.96, 95% CI 1.27-5.07), low consumption of foods of animal origin (3.5, 95% CI 1.18-3.61), low consumption of fruits and vegetables (2.33, 95% CI 0.86-2.63), among others. Conclusions: In the population of Chachapoyas, the factors considered in the study increase the risk of developing anemia in children under five years of age by more than 93%. Its probability of occurrence warrants a reevaluation of the strategies applied in the different programs or interventions carried out in the area for the control and prevention of anemia. (AU)

Desenho do estudo: Estudo retrospectivo de casos-controle. Objetivo: Identificar fatores de risco entre as ca-racterísticas sociodemográficas, nutricionais e de saúde associados à anemia por deficiência de ferro em crianças menores de cinco anos, atendendo à clínica de crescimento e desenvolvimento do Centro de Saúde Nueve de Enero de Chachapoyas em 2019. Método: Foram formados dois grupos, cada um formado por 50 crianças. O grupo 1 (G1, casos) eram crianças diagnosticadas com anemia por deficiência de ferro e um grupo controle (GC) de crianças saudá-veis, com idade compatível, residentes na mesma jurisdição. Os dados foram coletados dos registros médicos do cen-tro de saúde, em uma ficha de registro estruturada com base nas variáveis do estudo: idade, peso ao nascer, doenças parasitárias ou sintomas associados, como diarreia, frequência e tipo de alimentação antes e depois dos seis meses de idade. Os dados foram agrupados em tabelas de contingência para o cálculo do Odds Ratio (OR), e a significância esta-tística foi estimada pela análise de variância (ANOVA) com 95% de confiança. Resultados: Todos os fatores conside-rados apresentaram associação significativa p<0,05, com exceção do sexo, no que diz respeito à presença de anemia em crianças. Com valores OR de: menos de 32 meses de idade (OR=2,26, 95% CI 0,59-2,79), menos de 2900 g de peso ao nascer (OR=2,98, 95% CI 0,43-2,99), amamentação exclusiva prolongada (OR=3,14, 95% CI 1. 55-3. 88), ablactação precoce (OR=4,96, 95% CI 1,27-5,07), baixo consumo de alimentos de origem animal (3,5, 95% CI 1,18-3,61), baixo consumo de frutas e vegetais (2,33, 95% CI 0,86-2,63), entre outros. Conclusão: Na população de Chachapoyas, os fatores considerados no estudo aumentam em mais de 93% o risco de desenvolver anemia em crianças com menos de cinco anos. Sua probabilidade de ocorrência justifica uma reavaliação das estratégias aplicadas nos diferentes programas ou intervenções realizadas na área para o controle e prevenção da anemia.Palavras-chave: Fatores de risco, Anemia ferropriva, Anemia; Criança.

Prevalence of iron deficiency anemia in pregnancy and its therapeutic response to treatment: a retrospective audit in a tertiary hospital

Background: Iron deficiency anemia is the commonest type of nutritional anemia seen during pregnancy. Despite implementing oral iron prophylaxis in pregnancy,IDA in pregnant women constitute a major health problem. The present study aims to look at the prevalence of IDA in a pregnant population in Seremban, Malaysia and their response to treatment. Methods: This is a retrospective study looking into the prevalence of iron deficiency anaemia among pregnant women who delivered between October 2019 to March 2020 in a state hospital in Seremban, Malaysia and their response to treatment. Main outcome measures were the prevalence of iron deficiency anaemia, associated demographic and clinical factors and response to iron therapy. Results: About 920 patients� records were included for analysis. The prevalence of anaemia in this cohort was 42.8% (N=394). The prevalence of iron deficiency anemia (IDA) was 31.5% (N=124) among the anemic patients or 13.5% of the studied population. The mean hemoglobin level for this group was 10.0�74 g/dl (6.8-10.9 g/dl) and majority had mild anemia (91.9%, N=114). 68.5% IDA patients were successfully treated by 36 weeks pregnancy. Of the remaining 39 patients who were still anemic, 37 (94.9%) had mild anemia with mean hemoglobin level of 10.3g/dl (SD 0.48, range 9.0-10.9 g/dl). Conclusion: Current treatment strategy is inadequate to achieve the set national target. There is a role foran early recourse to parenteral iron therapy to improve treatment outcome.

Etiology and Risk Factors of Iron Deficiency Anemia in Children under Five Years: A Cross-sectional Study in 250 Bedded General Hospital, Thakurgaon

Background: Although there are several potential contributing factors to iron deficiency anemia in young children, eating foods with low levels of bioavailable iron is probably the biggest one. Young children are most at risk for iron deficiency due to fast development and usually insufficient dietary iron intake. The aim of this study was to assess the etiology and risk factors of iron deficiency anemia in children under five years.Material & Methods:This cross-sectional study was conducted in 250 bedded general hospital, Thakurgaon, Bangladesh, during the period from December 2020 to January 2022. Total 100 children having iron deficiency anemia under five years were included in this study.Results:Among 100 children with iron deficiency anemia, more than half (51%) of the children were in the age group of less than 1 year. Majority (52%) of the children were female. Most of the children (42%) were from low income family. More than half (65%) of the children had mild anemia. Inadequate iron-based food intake was the commonest (72%) causes of the study patient. Children taking iron supplementation was 14% and mothers taking iron supplementation during pregnancy was 67%. Dietary diversity score was poor for most of the children (59%). 67% had low birth weight and 28% had overweight. Children with early (<6 months) introduction of complementary foods was more than half (68%).Conclusions:Inadequate iron-based food intake is the commonest causes of iron deficiency anemia. Children mothers taking iron supplementation during pregnancy, low dietary diversity score, low birth weight and early (<6 months) introduction of complementary foods are the main risk factors.

A neglected cause of anaemia: hereditary hemorrhagic telangiectasia

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu syndrome is an inherited disorder characterized by vascular dysplasiasleading to hemorrhages. If affects approximately 1 in10,000 Caucasian people. The most common presentation is chronic and recurrent epistaxis whereas bleeding from other sites can lead to life-threatening complications.

Anemia Control Program in India Needs to be More Comprehensive

Iron?deficiency anemia has continued to remain high in India. It is possibly due to relying on only iron–folic acid (IFA) supplementation through Anemia Control Program (ACP) that is National Iron Plus Initiative (NIPI). Based on the WHO’s recommendations, we studied different interventions that can help to increase the effectiveness of NIPI such as Vitamin C supplementation with IFA, low?dose iron (LDI) with intensified health education (IHE), LDI with Vitamin C, and iron?rich food items to increase hemoglobin (Hb%) among adolescent girls through public–private partnership named Rashtriya Kishor Swasthya Karyakram. Increments in Hb after 12 weeks of interventions were compared with that of control groups one with NIPI and the other without any intervention. Highest increment in Hb% was observed in IFA under NIPI plus Vitamin C group, followed by LDI plus IHE group which was comparable to Hb increment in only the NIPI group. It emphasizes the need of making existing NIPI more stringent and comprehensive by integrating effective measures based on up?to?date scientific knowledge.

Central Retinal Vein Occlusion as a Presenting Feature Caused by Hypertensive Crisis Secondary to IgA Nephropathy

We present a case of Ischemic Central retinal vein occlusion (CRVO) caused by hypertension secondary to renal failure in IgA nephropathy. A 17 year old male came with chief complaints of sudden painless diminution of vision in RE since 15 days. On examination the Right eye showed multiple superficial retinal haemorrhages in all 4 quadrents with dilated veins and cystoid macular edema suggestive of CRVO and Left eye showed superficial flame shaped haemorrhage suggestive of grade 3 hypertensive changes.

A rare case of thrombocytosis presentation in patient alcoholic liver disease with portal hypertension gastropathy: a stepwise evaluation

Thrombocytosis is rarely found in patient with chronic liver disease (CLD). The possibility of reactive thrombocytosis could be due to sustained process such as iron deficiency anemia (IDA) because of occult bleeding. Occult bleeding can happen in CLD patient because of portal hypertension gastropathy (PHG) as complication of portal hypertension. A carefully evaluation of anemia can lead to underlying cause of disease, even in limited of supportive evaluationand some other confounding presentation that is thrombocytosis.We report a case of 54 years-old male patient with severe anemia. He had same symptom previously and got transfusion. Peripheral blood smear showed microcytic hypochromic anemia, anisocytosis, and poikilocytosis even pencil cells (pencil cells or cigar cells) with thrombocytosis. No symptom of acute inflammation setting and no clear blood loss was founded. As patient admitted to smoking and heavy alcohol consumption in the past, Ultrasound was performed for screening of underlying disease that cause occult bleeding. Ultrasound of the liver showed generally increased echogenicity suggestive of liver cirrhosis, splenomegaly and minimal ascites. Thus, our patient clinically be suggestive of CLD with portal hypertension that cause PHG.

Refractory iron deficiency anemia as an early manifestation of autoimmune gastritis in a teenager / Anemia ferropénica refractaria como presentación temprana de gastritis autoinmune en un adolescente

Abstract Autoimmune gastritis is an underdiagnosed disease in the pediatric population due to the absence of specific signs and symptoms and late clinical manifestations. Iron deficiency anemia has recently been identified as an early hematological manifestation, allowing an early diagnostic approach. We present the case of a Colombian teenager, with no history of autoimmunity, with refractory iron deficiency. He underwent extension studies; biopsies and serology compatible with autoimmune gastritis were documented, requiring parenteral iron in its evolution. This pathology is underdiagnosed in our context since early diagnosis requires a high index of suspicion to prevent associated complications.

Resumen La gastritis autoinmune es una enfermedad subdiagnosticada en la población pediátrica. Lo anterior se debe a la ausencia de signos y síntomas específicos y manifestaciones clínicas tardías. Recientemente se ha identificado la anemia ferropénica como una manifestación hematológica precoz, lo que permite un enfoque diagnóstico temprano. Se presenta el caso de un adolescente colombiano, sin antecedentes de autoinmunidad, con ferropenia refractaria, en el que se realizaron estudios de extensión y se documentaron biopsias y serología compatible con gastritis autoinmune, con requerimiento de hierro parenteral en su evolución. Esta patología es subdiagnosticada en nuestro medio, ya que el diagnóstico temprano requiere un alto índice de sospecha, lo que permite la prevención de las complicaciones asociadas.

Análise da anemia ferropriva e do estado nutricional de pacientes com doença renal crônica em tratamento hemodialítico em uma clínica de doenças renais do sul de Santa Catarina / Analysis of iron-deficiency anemia and nutritional status of patients with chronic kidney disease undergoing dialysis in a kidney disease clinic in southern Santa Catarina

Introdução: A desnutrição proteico-calórica encontrada em doentes renais crônicos (DRC) em tratamento hemodialítico, por vezes, culmina em anemias, devido à existência de fatores predisponentes comuns: nutrição deficiente, sessões de hemodiálise, medicações de uso contínuo. Nesta conjuntura, objetivou-se avaliar o estado nutricional e identificar a presença de anemia ferropriva nessa população. Métodos: Estudo de delineamento transversal realizado na Clínica de Doenças Renais, na cidade de Tubarão/SC. Totalizando 60 pacientes, a coleta foi feita por meio da análise de prontuários dos pacientes com doença renal crônica sob tratamento hemodialítico. Foram coletados dados laboratoriais para o diagnóstico de anemia ferropriva e avaliação de perfil nutricional através da aplicação do questionário SGA-Subjective Global Assessment. Resultados/Discussão: A média de idade foi de 59,47 ± 13,22, sendo 68,3% do sexo masculino e 31,7% do sexo feminino. A prevalência de anemia foi de 52,5%, sendo que, por deficiência de ferro, foi de 52,8%. Segundo o ASG modificado, a grande maioria dos pacientes (97,6%) se encontra em estado de desnutrição leve e, de acordo com o índice de massa corporal (IMC), 100% eram eutróficos. Conclusão: Observou-se que a maioria dos pacientes em tratamento encontra-se com desnutrição ou risco nutricional, sendo a reposição de ferro imperiosa, a fim de evitar complicações e agravo do quadro de anemia e debilidade nutricional. O acompanhamento do estado nutricional dos DRC sob tratamento é de extrema importância para reverter o quadro de desnutrição e amenizar os sintomas recorrentes dessa associação anemia e déficit nutricional.

Introduction: Protein-calorie malnutrition seen in patients with chronic kidney disease (CKD) undergoing hemodialysis sometimes results in anemias due to the existence of common predisposing factors: deficient nutrition, hemodialysis sessions, long-term medications. In this scenario, we aimed to evaluate nutritional status and to identify the presence of iron-deficiency anemia in this population. Methods: This is a cross-sectional study performed at Clínica de Doenças Renais in the city of Tubarão ­ Santa Catarina. Including a total of 60 participants, data were collected from the medical records of patients with chronic kidney disease undergoing hemodialysis. Laboratory data were used for diagnosing iron-deficiency anemia and the Subjective Global Assessment (SGA) questionnaire was used for analyzing nutritional profiles. Results/Discussion: The mean age was 59.47 ± 13.22, and 68.3% of the participants were male while 31.7% were female. The prevalence of anemia was 52.5%, of which 52.8% of the cases were due to iron deficiency. According to the modified SGA, most patients (97.6%) were in a state of mild malnutrition, and according to their body mass index (BMI), 100% were in the normal weight range. Conclusion: Most patients undergoing hemodialysis were in a state of malnutrition or nutritional risk, and iron replacement is essential to avoid complications and worsening of a clinical picture of anemia and nutritional deficiency. The follow-up of the nutritional status of patients with CKD undergoing treatment is extremely important to overturn the malnutrition state and alleviate the recurrent symptoms of this association of anemia and nutritional deficit.

Prevalência de anemia ferropriva e risco cardiovascular em pacientes hemodialíticos em uma clínica de doenças renais do sul de Santa Catarina / Prevalence of iron-deficiency anemia and cardiovascular risk in patients undergoing hemodyalisis at a kidney disease clinic in southern Santa Catarina

Introdução: A anemia por deficiência de ferro é observada em pacientes renais crônicos, conforme a perda da função renal. A suplementação de ferro é uma recomendação importante nesses pacientes. No entanto, uma sobrecarga desse mineral pode contribuir para o estresse oxidativo, o qual está diretamente relacionado à diminuição da função renal. Condição que predispõe ao risco cardiovascular devido à catálise na produção de radicais livres e oxidação de lipídios e catecolaminas. Métodos: Estudo de delineamento transversal realizado na Clínica de Doenças Renais, na cidade de Tubarão/SC. Totalizando 137 pacientes, coleta realizada por meio da análise de prontuários dos pacientes com doença renal crônica sob tratamento hemodialítico e estratificação de risco cardiovascular por meio do Escore de Framingham. Resultados: A prevalência de anemia foi de 56,6%, não havendo associação da mesma com risco cardiovascular (p=0,791). A ferritina apresentou-se diminuída em apenas 12,4%, e o ferro sérico com valores normais em sua maioria (70,8%). O risco cardiovascular elevado foi constatado em 51,1% dos pacientes e foi associado significativamente ao gênero, à idade, a diabete mellitus e à hipertensão arterial sistêmica. Conclusão: O tipo de anemia observado na maioria dos pacientes com Doença Renal Crônica sob tratamento hemodialítico foi a anemia da doença crônica, pois os valores de ferritina normais e/ou elevados foram responsáveis por 87,4% dos pacientes anêmicos. A maioria dos pacientes apresentou risco cardiovascular elevado (51,1%), e estavam associados às variáveis individuais de idade e gênero e às comorbidades hipertensão e diabetes, apesar de apresentarem os valores séricos lipídicos normais.

Introduction: Iron-deficiency anemia is observed in patients with chronic kidney disease as kidney function decreases. Iron supplementation is an important recommendation for these patients. However, an overload of this mineral can contribute to oxidative stress, which is directly related to decreases in kidney function. This condition predisposes patients to cardiovascular risk due to catalysis in free radical production and the oxidation of lipids and catecholamines. Methods: This is a cross-sectional study performed at Clínica de Doenças Renais in the city of Tubarão ­ Santa Catarina. A total of 137 patients participated in the study; data were collected by analyzing the medical records of patients with chronic kidney disease who underwent hemodialysis and cardiovascular risk stratification with the Framingham Risk Score. Results: The prevalence of anemia was 56.6% and no association was seen with cardiovascular risk (p=0.791). Ferritin levels were decreased in only 12.4% of the cases, and serum iron levels were normal in most patients (70.8%). High cardiovascular risk was observed in 51.1% of the patients, being significantly associated with gender, age, diabetes mellitus, and systemic arterial hypertension. Conclusion: The main type of anemia observed in patients with chronic kidney disease undergoing dialysis was anemia of chronic disease, since normal and/or increased ferritin levels were responsible for 87.4% of the anemic patients. Most patients presented high cardiovascular risk (51.1%), which was associated with individual variables of gender and age and with comorbidities such as hypertension and diabetes, despite presenting normal serum lipid levels.
