    Full Text Available La eritropoyetina recombinante (rHuEPO se ha transformado en la citoquina más utilizada terapéuticamente en el mundo. Luego del éxito obtenido en pacientes con insuficiencia renal terminal, se pudo establecer la utilidad de la terapia con rHuEPO para mejorar otras anemias, incluso en pacientes pediátricos y neonatos. El tratamiento o la prevención de la anemia del prematuro mediante el uso de rHuEPO llevó a una significativa reducción en cantidad de transfusiones y en exposición a dadores. Aún debe establecerse una clara definición sobre cuáles niños prematuros deben recibir tratamiento rutinariamente. Otras indicaciones en período neonatal incluyen anemias hiporregenerativas y hemolíticas. La eficacia de la rHuEPO en niños mayores, con excepción de la insuficiencia renal crónica, no ha sido tan exhaustivamente evaluada como en adultos. Mientras que durante los últimos años se han realizado gran cantidad de estudios en adultos con anemia asociada al cáncer o a infección por HIV, permitiendo establecer conclusiones claras sobre su eficacia, sólo escasa cantidad de estudios con pequeño número de pacientes han sido realizados en niños. Hasta la fecha, los resultados sugieren que la terapia con rHuEPO en niños es tan útil como en adultos, pero la realización de estudios aleatorizados prospectivos incluyendo gran número de pacientes es esencial para alcanzar conclusiones definitivas. Los resultados de estudios dirigidos a evaluar la eficacia de la rHuEpo para mantener una dosis adecuada de ribavirina en pacientes en tratamiento por hepatitis C son alentadores. La utilización potencial de los efectos no hemopoyéticos de la rHuEPO en neonatos es un terreno novedoso y apasionante. El rol de la Epo como citoprotector para sistema nervioso central y mucosa intestinal está bajo investigación exhaustiva.Recombinant human erythropoietin (rHuEpo has become the most widely used cytokine in the world.

    Introducción: el tratamiento de la anemia del prematuro consiste en la transfusión de glóbulos rojos y el uso de agentes estimulantes de la eritropoyesis. El objetivo de este trabajo es determinar la correlación entre el número de transfusiones sanguíneas y el uso de eritropoyetina recombinante humana en prematuros con anemia. Métodos: se realizó un estudio de correlación en 80 expedientes de pacientes con anemia tratados con transfusiones y eritropoyetina, se aleatorizaron en dos grupos: uno fue tratado con transfusiones (T) y otro con transfusiones y eritropoyetina (E). Se midieron variables demográficas, hemoglobina y hematócrito al inicio y al final del tratamiento y número de transfusiones recibidas. La correlación se obtuvo por medio de la Rho de Spearman, considerándose una p eritrocitos transfundidos fue negativa leve (-0.239). Para el grupo T la correlación entre las mismas variables negativa moderada (-0.300) y negativa leve (-0.109). Conclusiones: la eritropoyetina reduce el número de transfusiones sanguíneas en recién nacidos prematuros con anemia. Su uso no excluye la transfusión, el paciente continúa expuesto al riesgo de enfermedades transmisibles por esta vía.

    Full Text Available Introducción: La anemia es la anomalía hematológica y analítica más frecuente entre los pacientes críticos y quirúrgicos. Habitualmente se trata con transfusión de sangre alogénica (TSA, la cuál está relacionada con aumento de la morbimortalidad, por lo que se plantea la búsqueda de alternativas para el tratamiento de la anemia grave. Objetivos: Valorar la posible utilidad de la terapia con hierro intravenoso en pacientes con enfermedad crítica o quirúrgica que presentan anemia. Métodos: Revisión de los trabajos publicados con hierro intravenoso en este tipo de pacientes. Búsqueda en la base de datos Medline (www.ncvi.nlm.nih.gov y búsqueda manual. Resultado y discusión: El tratamiento con hierro intravenoso no es suficiente para tratar la anemia del paciente crítico. Su asociación a eritropoyetina sí puede tener un efecto sobre la tasa de transfusiones aunque no se ha demostrado que mejore la morbimortalidad ni la estancia hospitalaria. En cirugía digestiva o traumatológica no hay evidencia que apoye el tratamiento sistemático pericirugía con hierro intravenoso, pudiendo encontrarse beneficio cuando se utiliza junto con eritropoyetina. La utilización de hierro intravenoso solo o asociado a EPO en el postoperatorio no ha demostrado ser útil para una corrección rápida de la anemia, disminuir la estancia hospitalaria ni disminuir la mortalidad.Background: Anemia is a common condition among surgical and critically ill patients and it is usually treated with allogenic blood transfusion (ABT. As ABT is associated with increased morbidity and mortality, alternative therapies for anemia in these patients are actively investigated. Objectives: To asses the potential usefulness of intravenous iron therapy in critically-ill or surgical patients with anemia. Methods: Review of published papers with intravenous iron in these patients. Bibliographical search on database Medline (www.ncvi.nlm.nih.gov. Results and discussion

    Full Text Available La hepcidina, péptido antimicrobiano, cuya síntesis se encuentra regulada por el estado del hierro e inflamación, juega un importante papel en la homeostasis del hierro en pacientes hemodializados (HD. Es medida a través de la prohepcidina sérica. Objetivo: Determinar los niveles séricos de prohepcidina y su relación con ferritina sérica, proteína C reactiva (PCR y albúmina en pacientes HD tratados o no con eritropoyetina recombinante (EPO, que asistieron a un Centro de Salud del Estado Carabobo-Venezuela. Metodología: Esta investigación es de tipo descriptiva, correlacional y de campo, cuya muestra estuvo conformada por 71 pacientes HD; 57 de éstos tratados con EPO. Se determinó prohepcidina sérica, ferritina, hemoglobina, hematocrito, PCR y albúmina. Se definió anemia (hemoglobina 10 mg/L. Resultados: El promedio para la prohepcidina fue de 397,5 ng/mL. Se observó un alto porcentaje de anemia (87,3% y un 22,5% de pacientes con ferritina sérica baja. No se observaron diferencias estadísticamente significativas para ferritina, albúmina, PCR y prohepcidina, entre pacientes con y sin tratamiento con EPO. Solo la variable PCR se correlaciona significativamente (rho = 0,276; p =0,020, con prohepcidina. Conclusión: Pacientes HD presentan niveles elevados de prohepcidina, esto pudiera deberse al proceso inflamatorio frecuentemente observado en estos pacientes y no al estado de hierro medido a través de los niveles de ferritina sérica.Hepcidin, an antimicrobial peptide which synthesis is regulated by iron status and inflammation, plays an important role in iron homeostasis in hemodialysed (HD patients.

    Full Text Available La anemia es una de las complicaciones más comunes de la enfermedad inflamatoria intestinal. La alta frecuencia de valores bajos de hemoglobina en estos enfermos provoca en muchas ocasiones una infravaloración por parte del médico de esta circunstancia, lo que se traduce en la falta de un tratamiento eficaz. Por otro lado, el carácter complejo de los mecanismos de producción de la anemia en la enfermedad inflamatoria intestinal con frecuencia plantea dudas acerca del tratamiento más adecuado. La identificación correcta de los pacientes con anemia así como la instauración del tratamiento más idóneo serán los dos pilares fundamentales para la mejoría de la calidad de vida de los enfermos. El uso correcto de los suplementos de hierro y las nuevas formulaciones de hierro parenteral, con o sin eritropoyetina asociada, han revolucionado nuestro abordaje de esta complicación evolutiva de la enfermedad inflamatoria intestinalAnemia is a most common complication of inflammatory bowel disease. A high frequency of low hemoglobin values in these patients often leads physicians to subestimate this condition, which translates into ineffective treatment. On the other hand, the complex nature of anemia-inducing mechanisms in inflammatory bowel disease frequently raises doubt about the most appropriate therapy. A correct identification of patients with anemia, and adequate therapy are the essential pillars for improved quality of life. The right use of iron supplementation, and novel parenteral iron formulations, either with or without associated erythropoietin, have revolutionized our approach of this complication in the course of inflammatory bowel disease

    Anemias continue to present a challenge to the health care profession. Anemia is defined as a reduction in one or more of the RBC indices. Patients presenting with a mild form of anemia may be asymptomatic; however, in more serious cases the anemia can become life threatening. In many cases the clinical presentation also reflects the underlying cause. Anemia may be attributed to various causes, whereas autoimmune RBC destruction may be attributed to intrinsic and extrinsic factors. Laboratory tests are essential in facilitating early detection and differentiation of anemia.

    Full Text Available Many of the drugs that has shown promise in the treatment of hematologic malignancies and solid tumors, associated with a high potential cardiotoxic. Within this group stand anthracyclines, identified as the type of chemotherapy most likely to cause heart damage, short or long term. With the improvement achieved in the survival of patients with these diseases, this adverse event has become a major concern for the scientific community. Although many agents have been evaluated as potential cardioprotective therapeutic, clinical data are limited and does not suggest that the use of these agents promotes the survival of patients undergoing cardiotoxic treatments. The identification of erythropoietin receptor in hematopoietic tissues, including the heart, as well as its marked cardioprotective effect during ischemia have led to the hypothesis that erythropoietin may be able to prevent anthracycline-induced cardiomyopathy. Addressing this hypothesis is the objective of this work.Muchas de las drogas que han mostrado resultados alentadores en el tratamiento de las enfermedades hematológicas y los tumores sólidos, asocian un elevado potencial cardiotóxico. Dentro de este grupo sobresalen las antraciclinas, identificadas como el tipo de quimioterapia que con mayor probabilidad puede causar daño cardiaco, a corto o largo plazo. Con la mejoría alcanzada en la supervivencia de los pacientes portadores de estas enfermedades, este evento adverso se ha convertido en una de las principales preocupaciones para la comunidad científica. Aun cuando han sido muchos los agentes terapéuticos evaluados como posibles cardioprotectores, los datos clínicos disponibles son limitados y no permiten afirmar que el uso de estos agentes favorezca la supervivencia de los pacientes sometidos a tratamientos cardiotóxicos.

    Full Text Available La deficiencia de hierro es el trastorno hematológico más frecuente alrededor del mundo y afecta a 2,000 millones de personas aproximadamente, de los cuales 77 millones viven en América Latina y el Caribe. La deficiencia de hierro tiene un espectro que va desde la reducción y agotamiento de las reservas de hierro, hasta la reducción de las células rojas y de la concentración de hemoglobina. En consecuencia, hay deficiencias de hierro sin anemia. Los niños son uno de los grupos más vulnerables a esta deficiencia, debido al rápido período de crecimiento cerebral, en especial durante los dos primeros años de vida. El hierro es uno de los principales sustratos que soportan y permiten el desarrollo y la actividad metabólica de múltiples procesos a nivel cerebral, entre los cuales se encuentra el proceso de mielinización. Una insuficiente disponibilidad de hierro en un período de alta incorporación de éste en el tejido cerebral, que coincide con el período de mielinización del tejido nervioso, puede proveer una base fisiológica para explicar los efectos conductuales observados cuando hay deficiencias del micronutriente. De la misma manera, la deficiencia de hierro afecta la regulación y la conducción de neurotransmisores como la serotonina, la dopamina y GABA. La alteración de los receptores y transportadores de dopamina, compromete en los infantes las respuestas afectivas y el funcionamiento cognoscitivo, y los de los receptores GABA, la coordinación de patrones de movimiento y memoria. La importancia consiste que cuando ocurre un déficit de hierro cerebral en etapas tempranas, los daños ocurridos persisten en la etapa adulta, más allá de la recuperación de la anemia durante los primeros meses de vida. Estas alteraciones cerebrales se reflejan a largo plazo en un retraso del desarrollo mental y físico de los niños que han tenido anemia, y como consecuencia un menor desempeño escolar, con altos niveles de repetici

    Full Text Available Introducción: Los niños con enfermedades respiratorias crónicas (ERC tienen mayor riesgo de desarrollar anemia ferropriva, sin embargo, la ferropenia está infradiagnosticada. Objetivos: Describir el status de hierro (Fe en niños con ERC y evaluar la respuesta a su suplementación profiláctica. Método: Estudio prospectivo de niños con ERC y adecuada ingesta de Fe en la dieta: se realizó hemograma, velocidad de eritro-sedimentación, proteína C-reactiva y perfil de Fe. Posteriormente, aquellos con hemoglobina plasmática (Hb normal no se suplementaron con Fe (Grupo A y los que presentaban anemia ferropriva o factores de riesgo sí lo fueron (grupo B. Se evaluaron al 3º mes, después se suplementaron todos y se re-evaluaron al 4ºmes. Resultados: De 40 pacientes, con mediana de edad 30 meses (0,5 a 178, 60% eran hombres, 80% eutróficos. Requerían ventilación prolongada u oxigenoterapia 45%. Diagnósticos: 50% Bronquiolitis Obliterante post-infecciosa, 17,5% enfermedades de la vía aérea, 10% Displasia Broncopulmonar, 7,5% Fibrosis Quística y 15% otros. Basalmente 12,5% tuvo bajos depósitos de Fe y 20% anemia (la mayoría ferropriva. Completaron el estudio 25 niños: el grupo A disminuyó la ferritina sérica al 3ºmes (22,9 ± 30 y aumentó al 4ºmes (+12,8 ± 26 µg/L, (p = 0,013, sin cambio en la Hb. El grupo B tuvo ascenso de la Hb (91 ± 12 a 102 ± 12% del promedio para la edad, p = 0,04. Conclusión: La anemia ferropriva y la ferropenia son frecuentes en niños con ERC, quienes deterioran reversiblemente sus depósitos si no son suplementados. Sugerimos monitorizar con perfil de Fe y tratar precozmente, o suplementarlos en forma profiláctica.

  9. Transfusiones en pacientes con pruebas de compatibilidad positivas y en aquellos con anemia hemolítica autoinmune Approach to transfusion support in patients with positive compatibility tests and in those with autoimmune hemolytic anemia

    Directory of Open Access Journals (Sweden)

    2007-12-01

    Full Text Available Es frecuente la presencia de pruebas de compatibilidad positivas en pacientes que requieren soporte transfusional. Los pacientes con anemia hemolítica autoinmune presentan autoanticuerpos calientes o fríos que reaccionan contra antígenos de los eritrocitos y producen reacciones hemolíticas, que pueden ir desde leves hasta graves. Los pacientes multitransfundidos o con insuficiencia renal crónica o con anemia de células falciformes, presentan aloanticuerpos que dificultan el tratamiento con derivados de la sangre. La frecuencia de los mismos es hasta de 32% en algunas series. Dado el perfeccionamiento de las técnicas de laboratorio, en la actualidad son posibles la detección y determinación de la especificidad de los autoanticuerpos y aloanticuerpos; el enfoque integral del paciente y el conocimiento de dichas técnicas son los mejores fundamentos para un soporte transfusional seguro. Positive compatibility tests in patients who need blood transfusions are common. Patients with autoimmune hemolytic anemia may have warm or cool autoantibodies that react with red blood cell antigens and produce hemolytic transfusion reactions. Multitransfused patients, and those with either chronic renal disease or sickle cell disease, have alloantibodies that make blood transfusion difficult. In some series the frequency of such antibodies is as high as 32%. Detection and determination of specificity of autoantibodies and alloantibodies are now possible because of technical developments in laboratory. An integral approach to patients and the knowledge of these procedures are the best bases to offer secure blood transfusions.

    Full Text Available Las enfermedades vasculares constituyen las terceras causas de muerte en Cuba. Su variante isquémica es causa de invalidez y perdida de la calidad de la vida. La búsqueda de agentes neuroprotectores es muy importante sí tenemos en cuenta que nuestra población está envejecida. Muchos son las razones por la que una molécula con propiedades neuroprotectoras en los modelos animales no tenga los resultados en ensayos clínicos en humanos. Este trabajo analiza y discute como mejorar estos aspectos. La Eritropoyetina humana recombinante (rHu EPO, conocido por su papel en la diferenciación del eritrocito, ha mostrado ser neuroprotector durante la isquemia cerebral en los modelos de animales adultos. De esta molécula se exponen los mecanismos de acción, que son las bases de los resultados positivos alcanzaron en las investigaciones preclínicas y los ensayos clínicos, que lo proponen como el neuroprotector ideal. Finalmente se comparan los resultados alcanzados por los autores en las investigaciones con la rHu EPO producida por el Centro Molecular de Inmunología de Cuba (CIM. El efecto de la aplicación de rHu EPO se evidenció por la disminución del edema cerebral, preservación de la conducta exploratoria y la disminución de la incidencia de señales clínicas de infarto cerebral y alteraciones patológicas. El grupo de resultados demostró las diferencias significantes entre los animales controles y tratados con el rHu EPO con los no tratados que sugieren que el rHu EPO debe ser considerado como una alternativa terapéutica contra el infarto cerebral en su fase aguda.

    Full Text Available Background & aims: Iron deficiency anemia is a common complication of gastric surgery that in certain patients can be refractory to treatment with oral iron and needs to be treated parenterally. Methods: A 48-year woman underwent gastric surgery for a gastric ulcer. She was referred to the nutrition unit for the study and treatment of a 3-year iron deficiency anemia refractory to oral iron supplementation. Blood tests, endoscopy and jejunal biopsy were made to study the case. Results: Intestinal villi atrophy in the absence of celiac disease was the result. She was treated with intravenous iron, resolving the villous atrophy and thus oral iron supplementation could be effective. Conclusion: This case illustrates that iron deficiency may cause villous atrophy. In this setting, parenteral iron administration is necessary to correct the haematological and non-hematological alterations associated with this deficiency.Introducción y objetivos: La anemia ferropénica es una complicación frecuente tras la cirugía gástrica que en algunos pacientes puede ser refractaria al tratamiento con hierro oral, siendo necesaria su administración por vía parenteral. Métodos: Presentamos el caso de una mujer de 48 años intervenida de gastrectomía para tratamiento de una úlcera gástrica. Fue remitida a la unidad de nutrición para estudio y tratamiento de una anemia ferropénica de 3 años de evolución refractaria al tratamiento con hierro oral. Para el estudio del caso se realizó analítica y endoscopia digestiva alta con biopsia yeyunal. Resultados: En el estudio realizado la paciente presentaba atrofia de la mucosa yeyunal en ausencia de enfermedad celíaca. Fue tratada con hierro intravenoso desapareciendo la atrofia intestinal, tras lo cual continuamos con suplementos de hierro por vía oral. Conclusión: Este caso ilustra que la deficiencia de hierro puede producir atrofia intestinal. Si esto ocurre, es necesario la suplementación de este metal

El objetivo fue determinar la prevalencia de anemia en niños de la comunidad de Yvyraty (Paraguarí, Paraguay y evaluar su asociación con el estado nutricional. MATERIAL Y MÉTODO: Estudio observacional, descriptivo, de corte transverso con componente analítico. Se colectaron datos antropométricos y se extrajo sangre a una muestra de 94 niños entre 2 y 18 años. Para determinar la asociación entre sexo-anemia, y edad-anemia se utilizó la prueba de Chi-cuadrado; para determinar la asociación entre eosinofilia-hemoglobinemia; y estado nutricional-hemoglobinemia se utilizaron las pruebas de t de Student, y de Kruskal-Wallis respectivamente. En todos los casos se consideró significación estadística cuando p<0,05. RESULTADOS: La prevalencia de anemia en la muestra fue del 19,1%. A partir de la evaluación antropométrica se verificó que el 70,2% de los niños era normopeso, 14,9% estaba en riesgo de desnutrición, 6,4% con desnutrición moderada y 8,5% con sobrepeso. No se encontró diferencia significativa entre el sexo y la edad con la presencia de anemia (p=1 y p=0,4 respectivamente, ni entre los indicadores nutricionales agudos y crónicos con la hemoglobinemia (p=0,3 y p=0,5 respectivamente.

    Publicaciones recientes reflejan la preocupación de las autoridades antidopaje por el uso de sistemas simuladores de altitud y la posibilidad de considerarlos métodos dopantes. El objetivo de nuestro estudio fue el de comparar las modificaciones hematológicas inducidas por dos tratamientos con eritropoyetina recombinante humana (rHuEpo a diferentes dosis, frente a un protocolo de hipoxia normobárica intermitente (HNI en un modelo animal.
    Veinticuatro ratas Wistar macho jóvenes fueron divididas en 3 grupos experimentales: grupo sometido a HNI (12h pO2 12% /12h pO2 21% (n=8; grupo tratado con una dosis de 300 UI de rHuEpo (n=8 y grupo tratado con 500 UI de rHuEpo (n=8. Se extrajeron dos muestras de sangre a cada uno de los grupos experimentales (antes y después de los tratamientos. Nuestros resultados muestran incrementos muy similares, y estadísticamente significativos, en los valores de hemoglobina, de hematocrito y de reticulocitos, tanto en el grupo HNI como en el grupo tratado con 300 UI de rHuEpo tras los 15 días de tratamiento. El tratamiento con 500 UI de rHuEpo produjo un incremento significativamente mayor.
    La principal conclusión de nuestro estudio es que las modificaciones de los parámetros hematológicos obtenidas mediante un protocolo de HNI son similares a las obtenidas con un tratamiento con 300 UI de rHuEpo.

    Full Text Available This paper deals with avian anemia's classified by MCHC/MCV and with types of anemia's. Father hematological and immunological research is needed to secure information on hematological parameters in different avian species at their earliest age. Anemia is a common clinical finding in birds because the avian erythrocyte half - life is much shorter than the mammalian. Therefore anemia should be determined as soon as possible. Researchers should standardize hematological parameters for every single avian species.

Yet, there is a paucity of data on scholar children. Our main objective was to estimate the prevalence of ferropenic anemia in children’s 3 to 12 years of age living under conditions of poverty. A total of 323 children were included, 171 attended to a day care institution (group A and 152 were from the same community but not attended in the day care institution (group B. Hemoglobin (Hb, medium corpuscular volume (MCV and serum ferritin (SF were measured in all children. In those with Hb 38 mmol/l and SF <10 µg/l or TS <10%. There were no differences between the groups regarding age, weight, height, education, gender and housing conditions. Mean hemoglobin level was 12.6 g/dl (group A: 12.4g/dl vs. group B:12.7g/dl; p=0.012, and mean SF was 45 mg/l, without significant differences between groups. Prevalence of iron deficiency anemia was 2.5% (8/323 and iron deficiency was 4.4% (14/317, without significant differences between groups. These results persisted after controlling for confounding variables. In this group of children living under conditions of poverty in Argentina, iron deficiency anemia was uncommon. We attribute this phenomenon to local affordability of some inexpensive cuts of red meat.

    Science.gov (United States)

    Matthes, T

    2006-01-01

    Sideroblastic anemias are a heterogenous group of disorders characterized by the presence of sideroblasts in the bone marrow aspirate. Current classification schemes distinguish between diseases of the heme synthesis pathway and diseases of other mitochondrial pathways which can either be of primary origin (defects in mitochondrial DNA) or of secondary origin (defects in nuclear DNA). Although several distinct hereditary forms exist, sideroblastic anemias are most frequently acquired diseases and belong to the group of myelodysplastic syndromes with the propensity to develop into overt leukemia. Treatment is mainly supportive (vitamins, blood transfusions, cytokines) and only rarely are bone marrow transplantations performed. The molecular defects of a few hereditary forms have already been elucidated, but the genes involved in the acquired forms are still largely unknown.

    2013-06-01

    Hemodynamic changes occur in pregnancy to prepare for expected blood loss at delivery. Physiologic anemia occurs in pregnancy because plasma volume increases more quickly than red cell mass. Anemia is most commonly classified as microcytic, normocytic, or macrocytic. Iron deficiency anemia accounts for 75% of all anemias in pregnancy. Oral iron supplementation is the recommended treatment of iron deficiency anemia in pregnancy. Parenteral iron and erythropoietin can also be used in severe or refractory cases. Outcomes and treatments for other forms of inherited and acquired anemias in pregnancy vary by disease, and include nutritional supplementation, corticosteroids, supportive transfusions, and splenectomy.

    Humbert, J; Wacker, P

    1999-01-28

    We describe the four most common groups of neonatal anemia and their treatments, with particular emphasis on erythropoietin therapy. The hemolytic anemias include the ABO incompatibility (much more frequent, nowadays, than the Rh incompatibility, which has nearly disappeared following the use of anti-D immunoglobulin in postpartum Rh-negative mothers), hereditary spherocytosis and G-6-PD deficiency. Among hypoplastic anemias, that caused by Parvovirus B19 predominates, by far, over Diamond-Blackfan anemia, alpha-thalassemia and the rare sideroblastic anemias. "Hemorrhagic" anemias occur during twin-to-twin transfusions, or during feto-maternal transfusions. Finally, the multifactorial anemia of prematurity develops principally as a result of the rapid expansion of the blood volume in this group of patients. Erythropoietin therapy, often at doses much higher than those used in the adult, should be seriously considered in most cases of non-hypoplastic neonatal anemias, to minimise maximally the use of transfusions.

    Megaloblastic anemia is one of the acquired nutritional anemias that may complicate pregnancy. It is most often secondary to folic acid deficiency because folate requirements are increased during gestation. When the diagnosis of megaloblastic anemia is confirmed, appropriate therapy will initiate a rapid reversal of the anemia process. Because of the association between neural tube defects and folate deficiency, it is recommended that women of reproductive age take folic acid supplementation.

    Full Text Available Introduction: in inflammatory bowel disease (IBD iron deficiency anaemia (IDA is a very common disorder. Until recently, oral iron has been the mainstay therapy, nevertheless it has been associated with intolerance and noncompliance. Therefore, the goal of our study was to evaluate the efficacy of intravenous iron in IDA in IBD patients and the secondary aim was to investigate whether other potential factors could influence in the response to the treatment. Design: an open-label, prospective, consecutive, single centre study. Material and methods: we performed our study in patients with ulcerative colitis (UC or Crohn's disease (CD with severe anaemia or intolerance with oral iron.

    The laboratory evaluation of anemia begins with a complete blood count and reticulocyte count. The anemia is then categorized as microcytic, macrocytic or normocytic, with or without reticulocytosis. Examination of the peripheral smear and a small number of specific tests confirm the diagnosis. The serum iron level, total iron-binding capacity, serum ferritin level and hemoglobin electrophoresis generally separate the microcytic anemias.

    1981-06-01

    hereditary anemias of mice have been the chief objects of investigation. At present under study are four macrocytic anemias, five hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an ..cap alpha..-thalassemia, and a new target-cell anemia. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse. Each anemia is studied through: (a) characterization of peripheral blood values, (b) determinations of radiosensitivity under a variety of conditions, (c) measurements of iron metabolism and heme synthesis, (d) histological and biochemical study of blood-forming tissue, (e) functional tests of the stem cell component, (f) examination of responses to erythroid stimuli, and (g) transplantation of tissue between individuals of differently affected genotypes.

    Full Text Available Iron deficiency anemia (IDA is the most frequent form of anemia in pregnant women. Folic acid, vitamin B12 deficiency, and hemoglobinopathies are other causes of anemia in pregnancy. Finding the underlying cause are crucial to the management of the anemia. Anemia is defined as hemoglobin of <11 g/dl in the first and third trimester and <10.5 g/dl in second trimester. According to the literature, anemia, particularly severe anemia (Hb<7g/dl is associated with increased risk of maternal and perinatal mortality and morbidity, and long term adverse effects in the newborn. The association of hemoglobin levels to perinatal outcome has been shown to be U shaped with both high and low hemoglobin levels being associated adverse perinatal outcome such as low birth weight, increased stillbirths. Anemia in pregnancy is a major public health problem. Ideally a woman should have adequate iron stores when she conceives, in order meet to additional requirements of pregnancy. This review focuses on the occurrence, types, maternal and perinatal outcomes, prevention and treatment of anemia during pregnancy. [Archives Medical Review Journal 2013; 22(3.000: 300-316

    Macrocytic anemia, defined as a mean cell volume (MCV) ≥100 fL in adults, has a narrow differential diagnosis that requires evaluation of the peripheral blood smear as well as additional laboratory testing taken in conjunction with clinical information that includes patient history and physical examination findings. This review is an update on the approach to a patient with macrocytic anemia with attention paid to the differentiation of megaloblastic and non-megaloblastic macrocytic anemias. Critical to the determination of the diagnosis is the judicious use of laboratory testing and the evaluation of those findings in conjunction with the patient medical, surgical, and medication history.

    Fanconi anemia is a rare inherited disease characterized by congenital anomalies, growth retardation, aplastic anemia and an increased risk of acute myeloid leukemia and squamous cell carcinomas. The disease is caused by mutation in genes encoding proteins required for the Fanconi anemia pathway, a response mechanism to replicative stress, including that caused by genotoxins that cause DNA interstrand crosslinks. Defects in the Fanconi anemia pathway lead to genomic instability and apoptosis of proliferating cells. To date, 13 complementation groups of Fanconi anemia were identified. Five of these genes have been deleted or mutated in the mouse, as well as a sixth key regulatory gene, to create mouse models of Fanconi anemia. This review summarizes the phenotype of each of the Fanconi anemia mouse models and highlights how genetic and interventional studies using the strains have yielded novel insight into therapeutic strategies for Fanconi anemia and into how the Fanconi anemia pathway protects against genomic instability.

  7. Iron deficiency anemia in inflammatory bowel disease

    Institute of Scientific and Technical Information of China (English)

    Sindhu; Kaitha; Muhammad; Bashir; Tauseef; Ali

    2015-01-01

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease(IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia(IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used labora-tory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and con-venient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD.

  8. Megaloblastic anemia in Japan

    Directory of Open Access Journals (Sweden)

    Taguchi,Hirokuni

    1978-08-01

    Full Text Available Since 1903, 744 cases of megaloblastic anemia have been reported in Japan: 490 cases of pernicious anemia; 95 cases associated with pregnancy; 66 cases after gastrectomy; 22 cases of megaloblastic anemia of infants; 21 cases of folic acid deficiency other than pregnancy and 19 cases of vitamin B12 malabsorption after ileal resection. It is generally agreed among hematologists in Japan that pernicious anemia is relatively rare, as in other Asian countries. The diagnosis of pernicious anemia in Japan is usually made by stained marrow films, radioisotopic assay of serum vitamin B12, Schilling test and good response to vitamin B12 therapy. Serum folate level, intrinsic factor or its antibody, methylmalonic acid excretion, formiminoglutamic acid excretion and deoxyuridine suppression test are performed only at a small number of laboratories. The drugs of choice are hydroxocobalamin, deoxyadenosylcobalamin and methylcobalamin. Cyanocobalamin has nearly disappeared from commercial sources in Japan. Vitamin B12 administration is common in patients with neurological disorders. Megaloblastic anemia due to folic acid deficiency is extremely rare in Japan. Low serum folate levels are frequently observed among patients receiving anticonvulsants or in pregnant women, but in such samples megaloblastic anemia is almost never detected. The folic acid content of hospital diets indicates that satisfactory amounts of folate are taken in Japan. The intake of folic acid from rice is well over the minimum daily requirement of folate. Other factors in folic acid deficiency, such as food taboos, severe alcoholism and malabsorption syndrome are not frequently found in Japanese. The inadequate intake of folate was the critical factor in most reported cases.

    Anemia is defined as a hemoglobin level of less than the 5th percentile for age. Causes vary by age. Most children with anemia are asymptomatic, and the condition is detected on screening laboratory evaluation. Screening is recommended only for high-risk children. Anemia is classified as microcytic, normocytic, or macrocytic, based on the mean corpuscular volume. Mild microcytic anemia may be treated presumptively with oral iron therapy in children six to 36 months of age who have risk factors for iron deficiency anemia. If the anemia is severe or is unresponsive to iron therapy, the patient should be evaluated for gastrointestinal blood loss. Other tests used in the evaluation of microcytic anemia include serum iron studies, lead levels, and hemoglobin electrophoresis. Normocytic anemia may be caused by chronic disease, hemolysis, or bone marrow disorders. Workup of normocytic anemia is based on bone marrow function as determined by the reticulocyte count. If the reticulocyte count is elevated, the patient should be evaluated for blood loss or hemolysis. A low reticulocyte count suggests aplasia or a bone marrow disorder. Common tests used in the evaluation of macrocytic anemias include vitamin B12 and folate levels, and thyroid function testing. A peripheral smear can provide additional information in patients with anemia of any morphology.

    Full Text Available Introduction: We present the case of a 65 years- old woman who was admitted with a severe macrocytic anemia Hb= 5.7g/dl and diffuse bone pain. Biologically she has moderate thrombocytopenia 35 000/µl, a hepatic cytolysis and cholestatic syndrome. Material and method: The patient was extensively evaluated before presentation for a mild iron - deficiency anemia for which she underwent endoscopic examination of the upper and lower gastrointestinal tract- normal. The bone marrow aspiration on admission revealed a marked hyperplasia of the erythroblastic line with ~50% basophilic erythroblasts suggesting a regenerative erythroid hyperplasia. These changes along with the marked reticulocytosis on the peripheral blood smear oriented us towards a hemolytic anemia; Folic acid, vitamin B12, autoimmune tests and hemolytic tests were all normal. We continued the investigations with a thoraco-abdominopelvic computed tomography which identified diffuse demineralization, vertebral compactation and pelvic stress fractures. The breast examination revealed a right breast nodule, but the breast ultrasonography pleaded for benignity. Lacking a clear definitive diagnosis we decided to perform a bone marrow biopsy. Results: The osteo- medullary biopsy pointed towards a medullar invasion from a lobular mammary carcinoma; In these circumstances we performed an ultrasound guided biopsy of the right mammary lump thus histologically confirming a tumoral invasion of the bone marrow with subsequent anemia. The patient started chemotherapy in the Oncology ward. Conclusion: The particularity of this case consists in the pattern of anemia, which initially seemed iron deficient and afterwards macrocytic – apparently hemolytic and was actually due to the tumoral medullar invasion and also the nonspecific ultrasonographic appearance of the breast tumor.

    Anaemia is a problem that affects almost 10% over 65 years and 20% over 85 years. There is no physiological anaemia in the elderly. Any anaemia expresses the existence of a pathological process, regardless of its severity. Anaemia in the elderly is always associated with a poor prognosis that is in terms of mortality, morbidity and risk of fragility. The diagnostic approach to anemia in the elderly is the same as in younger individual. There are many causes of anaemia; anaemia balance is a complex diagnostic process. Most anaemias are due to a deficiency, chronic inflammation or comorbidity. However, in the elderly, the etiology of anaemia is often multifactorial. In a number of cases remain unexplained anaemia. In a number of cases, anemia remain unexplained. Treatment of anaemia is the treatment of the cause, but specific therapeutic aspects to the elderly should be considered, as among other martial substitution or use of erythropoietin (EPO).

    Anemia is the most frequent derailment of physiology in the world throughout the life of a woman. It is a serious condition in countries that are industrialized and in countries with poor resources. The main purpose of this manuscript is to give the right concern of anemia in pregnancy. The most common causes of anemia are poor nutrition, iron deficiencies, micronutrients deficiencies including folic acid, vitamin A and vitamin B12, diseases like malaria, hookworm infestation and schistosomiasis, HIV infection and genetically inherited hemoglobinopathies such as thalassemia. Depending on the severity and duration of anemia and the stage of gestation, there could be different adverse effects including low birth weight and preterm delivery. Treatment of mild anemia prevents more severe forms of anemia, strictly associated with increased risk of fetal-maternal mortality and morbidity.

    2015-01-01

    The anemia of chronic disease is an old disease concept, but contemporary research in the role of proinflammatory cytokines and iron biology has shed new light on the pathophysiology of the condition. Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

    The development of recombinant human erythropoietin and its introduction into the market in the late 1980s has significantly improved the quality of life of patients with chronic kidney disease (CKD) and reduced the need for blood transfusions. Starting from a cautious target, a progressive increase in the recommended hemoglobin levels has been observed over the years, in parallel with an increase in the obtained levels. This trend has gone together with the publication of findings of observational studies showing a relationship between the increase in hemoglobin levels and a reduction in the mortality risk, with the conduction of clinical trials testing the effects of complete anemia correction, and with the compilation of guidelines on anemia control in CKD patients by scientific societies and organizations. In the last two years, evidence of a possible increase in the mortality risk in those patients who were randomized to high hemoglobin levels has resulted in a decrease in the upper limit of the recommended Hb target to be obtained with erythropoietin stimulating agents (ESA), and consequently in a narrowing of the target range. Comparison of guidelines on anemia control in CKD patients is an interesting starting point to discuss single recommendations, strengthen their importance, or suggest new topics of research to fill up important gaps in knowledge.

    Introducción: la anemia gestacional todavía se considera un problema de salud pública en Brasil y se asocia con un mayor riesgo de morbilidad materno-fetal y el estado nutricional de los niños en el período posparto. Objetivo: evaluar la frecuencia de la anemia gestacional materna en recién nacidos y su relación con el estado nutricional del niño al nacer. Métodos: se obtuvieron datos antropométricos de las mujeres embarazadas y los recién nacidos. Se recogieron muestras de sangre de mujeres embarazadas y de cordón umbilical de los recién nacidos para su posterior análisis de hemoglobina, hematocrito, ADE, hierro, ferritina e índice de saturación de transferrina en dispositivos automatizados. Los resultados se presentan como media y la desviación estándar. Fue utilizado el software GraphPadinStat®, versión 3.0 y se aceptó un nivel de significación del 5%. Resultados: la frecuencia de anemia materna era de 53,7% y 32,6% en los recién nacidos. La mitad de los recién nacidos eran niños anémicos de madres anémicas. De las mujeres embarazadas con anemia, el 79,3% tenían anemia leve y el 20,7% moderada. La concentración media de hemoglobina y hematocrito fue menor en las mujeres embarazadas con anemia (9,7 ± 0,9 g/ dl y 29,8 ± 3,2%) en comparación con las no anémicas (11,9 ± 0,7 g/dl y 36,5 ± 2,7%), como se esperaba. El nivel de hierro de la madre se correlacionó positivamente con ferritina (r = 0,389; p = 0,01) a partir de la sangre del cordón umbilical. El peso, la longitud y la circunferencia de la cabeza de los niños nacidos de madres anémicas fueron: 3.375,9 ± 506,9 g, 51,2 ± 1,7 cm y 34,5 ± 1,5 cm, respectivamente, mientras que entre los recién nacidos de madres no anémicas fueron: 3.300,2 ± 458,4 g, 50,3 ± 2,0 cm y 34,2 ± 2,0 cm, respectivamente.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    Anemia is a common problem in obstetrics and perinatal care. Any hemoglobin below 10.5 g/dL can be regarded as true anemia regardless of gestational age. Reasons for anemia in pregnancy are mainly nutritional deficiencies, parasitic and bacterial diseases, and inborn red blood cell disorders such as thalassemias. The main cause of anemia in obstetrics is iron deficiency, which has a worldwide prevalence between estimated 20%-80% and consists of a primarily female population. Stages of iron deficiency are depletion of iron stores, iron-deficient erythropoiesis without anemia, and iron deficiency anemia, the most pronounced form of iron deficiency. Pregnancy anemia can be aggravated by various conditions such as uterine or placental bleedings, gastrointestinal bleedings, and peripartum blood loss. In addition to the general consequences of anemia, there are specific risks during pregnancy for the mother and the fetus such as intrauterine growth retardation, prematurity, feto-placental miss ratio, and higher risk for peripartum blood transfusion. Besides the importance of prophylaxis of iron deficiency, the main therapy options for the treatment of pregnancy anemia are oral iron and intravenous iron preparations.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Anemia is a form of blood disorder most often occurs in the community. Sickle cell anemia is anemia due to hemoglobinopathy caused by a change in the amino acid-6 of the ? globin chain. Sickle cell anemia is common in tropical areas of Africa and some parts of the region Saudi Arabia, India and the Mediterranean as well as black people in America. In addition there are also careers in various European countries. In pathophysiology, there are amino acid change from glutamic acid to valine in the ?-globin chain that causes red blood cells become sickle-shaped when deoxygenatied, but still be able to return to its normal shape when experiencing oxygenation. When the red blood cell membrane have been amended, the polymerization of red blood cells has become irreversible. Clinical picture seen in sickle cell anemia can be divided into two, namely: acute and chronic. Diagnosis can be done is to distinguish between heterozygous or homozygous sickle cell. Treatment provided in accordance with the clinical picture appears. Treatment that can be done is by blood transfusion, bone marrow transplant, anti-sickling drug delivery, and drug delivery to trigger the synthesis of HbF. Treatment still in the development stage is to use stem cells. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Warm autoimmune hemolytic anemia (AIHA) is defined as the destruction of circulating red blood cells (RBCs) in the setting of anti-RBC autoantibodies that optimally react at 37°C. The pathophysiology of disease involves phagocytosis of autoantibody-coated RBCs in the spleen and complement-mediated hemolysis. Thus far, treatment is aimed at decreasing autoantibody production with immunosuppression or reducing phagocytosis of affected cells in the spleen. The role of complement inhibitors in warm AIHA has not been explored. This article addresses the diagnosis, etiology, and treatment of warm AIHA and highlights the role of complement in disease pathology.

  14. Complement in hemolytic anemia.

    Science.gov (United States)

    Brodsky, Robert A

    2015-01-01

    Complement is increasingly being recognized as an important driver of human disease, including many hemolytic anemias. Paroxysmal nocturnal hemoglobinuria (PNH) cells are susceptible to hemolysis because of a loss of the complement regulatory proteins CD59 and CD55. Patients with atypical hemolytic uremic syndrome (aHUS) develop a thrombotic microangiopathy (TMA) that in most cases is attributable to mutations that lead to activation of the alternative pathway of complement. For optimal therapy, it is critical, but often difficult, to distinguish aHUS from other TMAs, such as thrombotic thrombocytopenic purpura; however, novel bioassays are being developed. In cold agglutinin disease (CAD), immunoglobulin M autoantibodies fix complement on the surface of red cells, resulting in extravascular hemolysis by the reticuloendothelial system. Drugs that inhibit complement activation are increasingly being used to treat these diseases. This article discusses the pathophysiology, diagnosis, and therapy for PNH, aHUS, and CAD.

    Full Text Available BACKGROUND: Sickle cell disease, the most common hereditary blood disease in the world, is the result of an atypical hemoglobin called S (Hb S which, when homozygous (Hb SS is the cause of sickle cell anemia. Changes of puberty, correlated with a delayed growth spurt, begin late in both male and female sickle cell anemia individuals with repercussions on sexuality and reproduction. The objectives of this exploratory and descriptive study were to characterize the development of sexuality in adults with sickle cell anemia by investigating the patient's perception of their sex life, as well as the information they had and needed on this subject. METHODS: Twenty male and female sickle cell anemia patients treated at the Hemocentro Regional de Uberaba (UFTM with ages between 19 and 47 years old were enrolled. A socioeconomic questionnaire and a semi-structured interview on sexuality, reproduction and genetic counseling were applied. RESULTS: This study shows that the sickle cell anemia patients lacked information on sexuality especially about the risks of pregnancy and the possible inheritance of the disease by their children. Moreover, the sexual life of the patients was impaired due to pain as well as discrimination and negative feelings experienced in close relationships. CONCLUSION: The health care of sickle cell anemia patients should take into account not only the clinical aspects of the disease, but also psychosocial aspects by providing counseling on sexuality, reproduction and genetics, in order to give this population the possibility of a better quality of life.

Requerían ventilación prolongada u oxigenoterapia 45%. Diagnósticos: 50% Bronquiolitis Obliterante post-infecciosa, 17,5% enfermedades de la vía aérea, 10% Displasia Broncopulmonar, 7,5% Fibrosis Quística y 15% otros. Basalmente 12,5% tuvo bajos depósitos de Fe y 20% anemia (la mayoría ferropriva). Completaron el estudio 25 niños: el grupo A disminuyó la ferritina sérica al 3ºmes (- 22,9 ± 30) y aumentó al 4ºmes (+12,8 ± 26) μg/L, (p = 0,013), sin cambio en la Hb. El grupo B tuvo ascenso de la Hb (91 ± 12 a 102 ± 12% del promedio para la edad, p = 0,04). Conclusión: La anemia ferropriva y la ferropenia son frecuentes en niños con ERC, quienes deterioran reversiblemente sus depósitos si no son suplementados. Sugerimos monitorizar con perfil de Fe y tratar precozmente, o suplementarlos en forma profiláctica.

    Full Text Available Anemia é uma complicação comum em pacientes com mieloma múltiplo (MM e ocorre em mais de 2/3 dos pacientes. Anemia de doença crônica, deficiência de eritropoetina (EPO devido à insuficiência renal e efeito mielossupressivo da quimioterapia são os principais mecanismos patofisiológicos que contribuem para o desenvolvimento de anemia no MM. Nos pacientes que obtêm remissão completa com tratamento quimioterápico, anemia usualmente se normaliza. Nos pacientes que não respondem ou apresentam recaída do mieloma, anemia freqüentemente persiste. As opções de tratamento dos pacientes anêmicos com MM incluem transfusões de hemácias e EPO recombinante humana. Essa proteína é biologicamente equivalente à EPO endógena e sua administração promove aumento dos valores de hemoglobina por tempo mais prolongado sem os riscos das transfusões de sangue. Vários estudos têm relatado melhora significante da eritropoese, redução da necessidade transfusional e melhora da qualidade de vida com o uso da EPO como tratamento a longo prazo da anemia associada ao mieloma. Nesse artigo, propomos o tratamento da anemia do MM baseado nas recomendações propostas pela Sociedade Americana de Hematologia (ASH em conjunto com a Sociedade Americana de Oncologia Clínica (ASCO, pela Organização Européia para Pesquisa e Tratamento do Câncer (EORTC, pelo IMF (Internacional Myeloma Foundation e pelo NCCN (National Comprehensive Cancer Network.Anemia is a common complication in patients with multiple myeloma (MM occurring in more than two thirds of all patients. Anemia of chronic diseases, erythropoietin (EPO deficiency due to renal impairment and the myelosuppressive effect of chemotherapy are the most important pathophysiological mechanisms contributing to the development of anemia in MM. In patients who achieve complete remission after chemotherapy, anemia usually normalizes. Non-responders and relapsing myeloma patients often continue to suffer

    Aplastic Fanconi anemia (FA) accompanying malformation was firstly reported in 1927. This review concerns the recent findings on FA. FA belongs to the chromosomal instability syndrome and its detailed molecular mechanism is still unknown. The disease has been defined to be highly sensitive to radiation, however, which is quite an important problem since irradiation with a large dose of radiation is required before its radical treatment (bone marrow transplantation). FA cells are also mitomycin C-sensitive and FA patients are said to be the mosaic of the sensitive and normal cells. This enables to classify FA into 8 types of A-H groups, whose genotypes (FAA-FAH, FANCA-FANCH) are becoming clear. However, the intracellular function of the FANC-expressed protein, although known to form a big complex, is not elucidated yet. There is an abnormality in DNA processing such as re-linkage of the double strand-broken DNA in FA cells. FA causal gene FANCG is found identical to XRCC9 which is associated to high sensitivity to radiation. Analysis of FANC genes will provide useful findings on molecular mechanism of DNA-repair.

    2009-10-07

    Most anemia is related to the digestive system by dietary deficiency, malabsorption, or chronic bleeding. We review the World Health Organization definition of anemia, its morphological classification (microcytic, macrocytic and normocytic) and pathogenic classification (regenerative and hypo regenerative), and integration of these classifications. Interpretation of laboratory tests is included, from the simplest (blood count, routine biochemistry) to the more specific (iron metabolism, vitamin B12, folic acid, reticulocytes, erythropoietin, bone marrow examination and Schilling test). In the text and various algorithms, we propose a hierarchical and logical way to reach a diagnosis as quickly as possible, by properly managing the medical interview, physical examination, appropriate laboratory tests, bone marrow examination, and other complementary tests. The prevalence is emphasized in all sections so that the gastroenterologist can direct the diagnosis to the most common diseases, although the tables also include rare diseases. Digestive diseases potentially causing anemia have been studied in preference, but other causes of anemia have been included in the text and tables. Primitive hematological diseases that cause anemia are only listed, but are not discussed in depth. The last section is dedicated to simplifying all items discussed above, using practical rules to guide diagnosis and medical care with the greatest economy of resources and time.

    Subramaniam, Girish; Girish, Meenakshi

    2015-06-01

    Iron deficiency is not just anemia; it can be responsible for a long list of other manifestations. This topic is of great importance, especially in infancy and early childhood, for a variety of reasons. Firstly, iron need is maximum in this period. Secondly, diet in infancy is usually deficient in iron. Thirdly and most importantly, iron deficiency at this age can result in neurodevelopmental and cognitive deficits, which may not be reversible. Hypochromia and microcytosis in a complete blood count (CBC) makes iron deficiency anemia (IDA) most likely diagnosis. Absence of response to iron should make us look for other differential diagnosis like β thalassemia trait and anemia of chronic disease. Celiac disease is the most important cause of true IDA not responding to oral iron therapy. While oral ferrous sulphate is the cheapest and most effective therapy for IDA, simple nonpharmacological and pharmacological measures can go a long way in prevention of iron deficiency.

  4. Hereditary sideroblastic anemia: pathophysiology and gene mutations.

    Science.gov (United States)

    Harigae, Hideo; Furuyama, Kazumichi

    2010-10-01

    Sideroblastic anemia is characterized by anemia with the emergence of ring sideroblasts in the bone marrow. Ring sideroblasts are erythroblasts characterized by iron accumulation in perinuclear mitochondria due to impaired iron utilization. There are two forms of sideroblastic anemia, i.e., inherited and acquired sideroblastic anemia. Inherited sideroblastic anemia is a rare and heterogeneous disease caused by mutations of genes involved in heme biosynthesis, iron-sulfur (Fe-S) cluster biogenesis, or Fe-S cluster transport, and mitochondrial metabolism. The most common inherited sideroblastic anemia is X-linked sideroblastic anemia (XLSA) caused by mutations of the erythroid-specific δ-aminolevulinate synthase gene (ALAS2), which is the first enzyme of heme biosynthesis in erythroid cells. Sideroblastic anemia due to SLC25A38 gene mutations, which is a mitochondrial transporter, is the next most common inherited sideroblastic anemia. Other forms of inherited sideroblastic anemia are very rare, and accompanied by impaired function of organs other than hematopoietic tissue, such as the nervous system, muscle, or exocrine glands due to impaired mitochondrial metabolism. Moreover, there are still significant numbers of cases with genetically undefined inherited sideroblastic anemia. Molecular analysis of these cases will contribute not only to the development of effective treatment, but also to the understanding of mitochondrial iron metabolism.

    2015-01-01

    Anemia affects one-fourth of the world’s population, and iron deficiency is the predominant cause. Anemia is associated with chronic fatigue, impaired cognitive function, and diminished well-being. Patients with iron deficiency anemia of unknown etiology are frequently referred to a gastroenterologist because in the majority of cases the condition has a gastrointestinal origin. Proper management improves quality of life, alleviates the symptoms of iron deficiency, and reduces the need for blood transfusions. Treatment options include oral and intravenous iron therapy; however, the efficacy of oral iron is limited in certain gastrointestinal conditions, such as inflammatory bowel disease, celiac disease, and autoimmune gastritis. This article provides a critical summary of the diagnosis and treatment of iron deficiency anemia. In addition, it includes a management algorithm that can help the clinician determine which patients are in need of further gastrointestinal evaluation. This facilitates the identification and treatment of the underlying condition and avoids the unnecessary use of invasive methods and their associated risks. PMID:27099596

    2015-12-01

    Biermer disease or pernicious anemia is an autoimmune atrophic gastritis characterized by the lack of secretion of gastric intrinsic factor. This leads to an insufficient absorption of vitamin B12 in the ileum. Clinical manifestations are mainly hematologic. Neuropsychiatric manifestations are known but are less frequent especially early in the disease. Inaugural neuropsychiatric arrays are rare and various thus making diagnosis difficult. In this article, we report through two clinical cases different neuropsychiatric manifestations revealing pernicious anemia. Mrs. C.O., aged 56, presented after surgery for gallstones, an acute psychiatric array associated with gait disorders. She had no history of neurological or psychiatric problems. The psychiatric interview revealed delirious syndrome, depressive symptoms and anxiety. Neurological examination noted a flaccid paraplegia with peripheral neuropathic syndrome and myoclonus in the upper limbs. At the full blood count, a macrocytosis (VGM: 112.2fl) without anemia was found. The level of vitamin B12 in the blood was low. Cerebro-spinal MRI was suggestive of a neuro-Biermer and showed hyper signal in the cervical cord on T2-weighted sagittal section. In axial section, hyper signal appears at the posterior columns in the form of V. There were no brain abnormalities. A sensorimotor axonal polyneuropathy was diagnosed. The patient received vitamin B12 intramuscularly for ten days associated with neuroleptic treatment. Mrs. R.M., aged 40, was brought to the psychiatry consultation for acute behavioral disorders progressively worsening over a month. An anxiety syndrome, depressive syndrome and delirious syndrome were identified. Neurological examination showed a posterior cordonal syndrome with quadripyramidal syndrome. Full blood count showed a macrocytic anemia. Serum B12 level was collapsed. Cerebro-spinal MRI was normal. She received vitamin B12 with clinical and biological improvement.

    2006-01-01

    Full Text Available A normocytic normochromic anemia is one of the first signs of renal failure. Since anemia increases morbidity and mortality, its elimination is one of the essential objectives of the treatment. Human recombinant erythropoietin (rHuEPO has changed the therapeutical approach to anemia. The aim of the present study was to compare efficacy of anemia correction in peritoneal dialysis patients depending on treatment and dialysis modality. The study is the retrospective analysis of 64 patients who presented to our Clinic in 2003. Eighteen (28.13% patients were treated with rHuEPO, 14 (28% underwent continuous ambulatory peritoneal dialysis (CAPD, 2 (100% - automated peritoneal dialysis (APD and 2 (33.3% - intermittent peritoneal dialysis (IPD. Mean hemoglobin level was 98.6±17.82 g/l in patients treated with rHuEPO versus 98.81±15.14 g/I in patients without rHuEPO treatment. Erythropoietin requirements were 3392.85±1211.77 IU/week. AII patients received iron supplementation during rHuEPO therapy. Mean serum ferritin levels were 463.41 ±360 μg/l. Transferrin saturation (TSAT was 0.35±0.16%. No difference of serum iron and TSAT levels was found between CAPD and IPD patients. The degree of anemia significantly differed between CAPD and IPD patients. A total of 17.11% of PD patients were given blood transfusions, most frequently during the first three months after the onset of dialysis. Our conclusion is that the number of patients receiving rHuEPO should be increased, as 50% of our patients should be substituted, while only 28% are being treated. As 50% of patients receiving rHuEPO failed to reach target Hgb levels, higher EPO doses should be considered. Iron stores should be continuously monitored, particularly in patients receiving rHuEPO, since iron deficiency is an important problem for patients undergoing peritoneal dialysis, especially during erythropoietin therapy. Oral iron supplementation is satisfactory in the majority of patients, and

    Full Text Available Fanconi Anemia (FA is a rare autosomic recessive and X-linked disease with chromosomal instability after exposure to crosslinking agents as the hallmark. Clinical features of FA are somatic malformations, progressive bone marrow failure and cancer proneness, however there is wide clinical heterogeneity. The symptom most frequently and early associated with morbidity and mortality is progressive pancytopenia in the first decade of life although acute myelogenous leukemia (AML or myelodysplastic syndrome (MDS can appear before aplastic anemia. Squamous cell carcinoma (SCC of the head-neck, intestinal or genital tract has a very high incidence in FA and can appear at young age. This paper will focus on treatment of bone marrow failure in FA.

    Diamond-Blackfan anemia is a rare, inherited disease that characteristically presents as a chronic, normochromic macrocytosis due to red cell lineage bone marrow failure. Although studies are elaborating on the genetic basis for its associated comorbidities, little has been published comparing this anemia to other chronic anemias that have similar laboratory results in children. This article offers a global perspective of the disease and compares it with anemia due to vitamin B12 and folate deficiency in children.

    Full Text Available La malaria es una enfermedad infecciosa de transmisión vectorial, que compromete enormemente la salud y el desarrollo socioeconómico de comunidades localizadas en regiones tropicales y subtropicales de todo el mundo. Se estima que globalmente, se registran cerca de 500 millones de casos clínicos cada año, los cuales son producidos por 4 especies diferentes de Plasmodium, siendo las más prevalentes las infecciones por P. falciparum y el P. vivax. Las manifestaciones clínicas de la malaria son bastantes pleomórficas y se pueden extender desde episodios febriles de corta duración, si el diagnóstico es oportuno y el tratamiento efectivo, hasta complicaciones sistémicas severas y muerte. Parte muy importante de la morbi-mortalidad está asociada con el desarrollo de anemia, una de las manifestaciones clínicas más frecuentes y uno de los mayores obstáculos para el desarrollo de las áreas endémicas por el compromiso que produce en el rendimiento escolar de los niños y en la productividad de los adultos. La fisiopatología de la anemia no se conoce completamente, pero se acepta que es producida por múltiples mecanismos que incluyen la destrucción de eritrocitos infectados y no infectados, la eritro-fagocitosis y un freno potencial de la eritropoyesis. La anemia aumenta significativamente la severidad y por consiguiente la mortalidad de la enfermedad y su tratamiento no siempre está dirigido a solucionar la causa de la misma. Este artículo discute los mecanismos involucrados en la producción de anemia en la malaria conocidos hasta el momento, el tratamiento y las implicaciones potenciales de vacunas dirigidas a prevenir esta complicación.

  12. [Anemia in patients with rheumatoid arthritis].

    Science.gov (United States)

    Wahle, M

    2012-12-01

    One of the most frequent extra-articular organ manifestations in rheumatoid arthritis (RA) is anemia. As anemia in RA patients may result in severe symptoms and aggravation of other disease manifestations (e.g. arteriosclerosis), the influence on the course of RA is profound. However, the importance of anemia in RA patients is frequently underestimated. The etiology of anemia in RA is complex. Anemia of inflammation (AI) and iron deficiency anemia, alone or in combination are the most frequent forms of anemia in RA. Changes in iron metabolism are the leading causes of anemia in RA patients and mainly induced by the altered synthesis and function of hepcidin and ferroportin. Hepcidin, a peptide produced in the liver and immunocompetent cells, impairs the expression of ferroportin on iron-secreting cells, thus reducing iron bioavailability. The typical changes of iron metabolism and hepcidin synthesis in RA are induced by proinflammatory cytokines, primarily interleukin-6. Hence, the treatment of RA with cytokine antagonists has significant therapeutic implications on anemia in the context of inflammation and impaired iron metabolism.

    Full Text Available OBJETIVO: Describir la prevalencia informada de anemia por deficiencia de hierro en mujeres mexicanas en edad reproductiva en los últimos 66 años y analizar la eficacia de las intervenciones informadas para su prevención y manejo. MATERIAL Y MÉTODOS: Revisión de estudios epidemiológicos observacionales, clínicos y programas gubernamentales de intervención, publicados entre 1939 y 2005 con información original. Se consultaron las bases de datos de la Biblioteca Nacional de Medicina de Estados Unidos, Artemisa e índices de revistas mexicanas. La calidad de los ensayos clínicos se evaluó con base en la escala Jadad. Las tendencias de la prevalencia de anemia se analizaron con una regresión lineal ponderada por el tamaño muestral. RESULTADOS: Se incluyeron 46 trabajos de investigación; nueve correspondieron a ensayos clínicos y cuatro a programas operativos; 17 informaron la prevalencia de anemia en no embarazadas y 23 en gestantes. En el primer grupo, la prevalencia ponderada de anemia ha descendido de 39.6 a 15.5%, en tanto que en las gestantes ha disminuido 10 puntos porcentuales, hasta 25%. De los estudios clínicos, 55% se consideraron con un nivel de evidencia adecuado. CONCLUSIONES: La anemia en mujeres en edad reproductiva, y particularmente en las embarazadas, aún constituye un problema de salud pública. De seguir con los esquemas actuales, se requerirían cerca de 57 años para erradicar la anemia entre las no gestantes y 121 para las gestantes.

    We conducted a cross sectional study to investigate risk factors associated with severe anemia [hemoglobin (Hb) iron status among Nepali pregnant women. Socio-demographic, anthropometric, health and dietary data were collected from 3,531 women living in the southeastern plains of Nepal. Stool samples were analyzed for intestinal helminthes. Dark adaptation was assessed using the Night Vision Threshold Test (NVTT). Hb levels were measured in all subjects to detect anemia and the soluble transferrin receptor (sTfR) was measured among a subsample of 479 women. The iron status categories were: 1) normal (Hb> or = 11.0 g/dl and sTfR anemia without iron deficiency (Hbiron deficiency without anemia (Hb > or = 11.0 g/dl and sTfR>8.5 mg/l); and 4) iron deficiency anemia (IDA): (Hb8.5 mg/l). Factors associated with severe anemia and poor iron status were determined using logistic regression. Hookworm infection increased the risk for developing severe anemia [adjusted odds ratio (AOR): 4.26; 95% CI 1.67-10.89; piron deficiency with and without anemia. Intake of iron supplements as tablets and/or tonic was protective against severe anemia, anemia without iron deficiency and IDA. Dietary heme iron was significantly associated with iron deficiency without anemia (RRR: 0.1; 95% CI 0.02-0.47; panemia and associated nutrient deficiencies.

  11. Unexplained Aspects of Anemia of Inflammation

    Directory of Open Access Journals (Sweden)

    Elizabeth A. Price

    2010-01-01

    Full Text Available Anemia of inflammation (AI, also known as anemia of chronic inflammation or anemia of chronic disease was described over 50 years ago as anemia in association with clinically overt inflammatory disease, and the findings of low plasma iron, decreased bone marrow sideroblasts and increased reticuloendothelial iron. Pathogenic features underlying AI include a mild shortening of red cell survival, impaired erythropoietin production, blunted responsiveness of the marrow to erythropoietin, and impaired iron metabolism mediated by inflammatory cytokines and the iron regulatory peptide, hepcidin. Despite marked recent advances in understanding AI, gaps remain, including understanding of the pathogenesis of AI associated with “noninflammatory” or mildly inflammatory diseases, the challenge of excluding iron deficiency anemia in the context of concomitant inflammation, and understanding more precisely the contributory role of hepcidin in the development of AI in human inflammatory diseases.

    The endothelium plays an important role in sickle cell anemia (SCA) pathophysiology, interacting with red cells, leukocytes and platelets during the vaso-occlusive process and undergoing activation and dysfunction as a result of intravascular hemolysis and chronic inflammation. Blood outgrowth endothelial cells (BOECs) can be isolated from adult peripheral blood and have been used in diverse studies, since they have a high proliferative capacity and a stable phenotype during in vitro culture. This study aimed to establish BOEC cultures for use as an in vitro study model for endothelial function in sickle cell anemia. Once established, BOECs from steady-state SCA individuals (SCA BOECs) were characterized for their adhesive and inflammatory properties, in comparison to BOECs from healthy control individuals (CON BOECs). Cell adhesion assays demonstrated that control individual red cells adhered significantly more to SCA BOEC than to CON BOEC. Despite these increased adhesive properties, SCA BOECs did not demonstrate significant differences in their expression of major endothelial adhesion molecules, compared to CON BOECs. SCA BOECs were also found to be pro-inflammatory, producing a significantly higher quantity of the cytokine, IL-8, than CON BOECs. From the results obtained, we suggest that BOEC may be a good model for the in vitro study of SCA. Data indicate that endothelial cells of sickle cell anemia patients may have abnormal inflammatory and adhesive properties even outside of the chronic inflammatory and vaso-occlusive environment of patients.

    Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial.

    Full Text Available Introduction. The problem of anemia in congestive heart failure and chronic kidney disease was thought to be insignificant for a long period of time. Recent investigations pointed out that the problem of anemia should be defined in the context of the cardio-renal anemia syndrome. A positive feedback mechanism indicates that cardio-renal anemia syndrome is due to an interaction between congestive heart failure, chronic renal failure and anemia. The aim of the study was to present the possible pathophysiological mechanisms of this syndrome, epidemiological characteristics and therapeutic results of the former investigations. Results. The results of the retrospective and prospective controlled trails have shown that management of anemia with subcutaneous administration of recombinant human erythropoietin together with intravenous iron infusion for at least 3-6 months lead to: relief of symptoms (improved NYHA functional class; increased left ventricular ejection fraction; reduced cardiovascular morbidity and mortality; reduced number of rehospitalizations; reduced requirements for usual therapeutic agents (especially diuretics; and improved renal function. Conclusion. In patients with heart and kidney disease anemia should be routinely identified and appropriately treated. Subcutaneous recombinant erythropoietin and intravenous iron may significantly improve overall survival and quality of life of these patients. .

    Iron-deficiency anemia is the most common anemia in infants. In the routine pediatric care this problem is encountered every day. Numerous factors in infancy (low birth weight, rapid growth, insufficient nutrition) are involved in the development of iron-deficiency anemia, and they must be considered when establishing diagnosis, counselling parents, and prescribing oral iron preparations. Data on 119 patients aged up to two years treated in the Division of Gastroenterology and Nutrition, Pediatric Department, University Hospital Centre Zagreb Salata between 1994 and 1999, were analyzed. We were prompted to do so because of great frequency of iron-deficiency anemia as one of associated diagnoses, and unfortunately often the only diagnosis requiring hospitalization. Out of 119 patients with iron-deficiency anemia, nine (7.7%) patients (four premature newborns and three from twin pregnancy) had to receive transfusion of erythrocyte concentrate due to very bad general condition and low red blood count, accompanied by clinical signs of anemic hypoxia. We also analyzed prenatal and perinatal history, socioeconomic living conditions of these children, i.e. their nutrition, and if they had previously received oral iron preparations. Some of the results, such as inadequate alimentation with flour, as well as insufficient prophylaxis of iron deficiency, which were found in most cases of severe anemia, point to the need of paying greater attention to this problem, better parents education, and more adequate screening for iron deficiency anemia.

    Full Text Available The numbers of older people in the world have been growing rapidly. Anemia is the most common hematologic problem encountered in older adults. However, anemia should not be accepted as an inevitable consequence of aging. Anemia in the elderly signifies an underlying disease. Iron Defi ciency Anemia (IDA is being one of the most common causes of anemia in older people. IDA in the elderly is often associated with such non specific symptoms. The diagnosis of IDA is typically based on laboratory results. Hence, the utilization of the various laboratory tests plays an important role for the diagnosis of IDA. The presence of IDA in the elderly is usually related with gastrointestinal disorders. Thus,  gastrointestinal evaluation should be contemplated in all patients with IDA unless there is a history of clinically important non gastrointestinal blood loss. Older people with IDA should have iron supplementation both to correct anemia and to replenish body iron stores. However, the underlying cause should always be treated to prevent further iron loss.

    Hereditary anemias of mice are the chief objects of investigation, specificially four macrocytic anemias, 3 types of hemolytic anemia, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, the autoimmune hemolytic anemia of NZB mice, an ..cap alpha..-thalassemia and a new hypochromic anemia with hemochromatosis. New types of anemia may be analyzed as new mutations appear. Three new mutations have been identified during the past 18 months. These anemias are studied through characterization of peripheral blood values, determinations of radiosensitivity under a variety of conditions, measurements of iron metabolism and heme synthesis, study of normal and abnormal erythrocyte membrane proteins, histological and biochemical characterization of blood-forming tissue, functional tests of the stem-cell component, examination of responses to erythroid stimuli, and transplantation of tissue and parabiosis between individuals of differently affected genotypes. 31 refs.

    Full Text Available Resumen La anemia es común en la insuficiencia cardiaca, y se asocia a una mayor morbimortalidad. Sin embargo, no está claro si corregirla con agentes estimulantes de la eritropoyesis se traduce en un beneficio clínico. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos 11 revisiones sistemáticas que en conjunto incluyen 17 estudios aleatorizados. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que el uso de agentes estimulantes de la eritropoyesis en pacientes con insuficiencia cardiaca y anemia no disminuye la mortalidad, y que no está claro si disminuye las hospitalizaciones o si mejora la capacidad funcional porque la certeza de la evidencia es muy baja. Probablemente aumenta el riesgo de eventos tromboembólicos totales.

    Full Text Available Background: Anemia during pregnancy is a global public health challenge facing the world today. Prevalence of anemia in pregnancy in all the age groups is higher in India as compared to other developing countries. Objective: This study is aimed at determining the magnitude and to explore the socio-demographic and other correlates of anemia among pregnant women. Methodology: This descriptive study with cross-sectional design was conducted in a tertiary care hospital. Pregnant who were attending antenatal clinic for a period of one year were comprised the study material. Correlation between variables was analyzed using the chi-square and odd ratio. Results: Three hundred and thirty eight pregnant women were registered for the present study, whose age ranged from 16 to 45 years with a mean age of 26.08 years. Majority (81.95% participants were found to be anemic. It was observed that anemia was more prevalent in pregnant women age groups i.e. 25-29 years and 30+years i.e. 86.67% and 86.21% respectively. Anemia was 82.92% in women were belonging to Hindu and others religion and 82.24% in women having vegetarian diet. Maximum prevalence (83.93% of anemia was observed in women who were booked for antenatal care in the 3rd trimester of pregnancy. The prevalence of anemia is higher (>85% in women having parity two or more, but this association was not statistically significant. Very few (6.21% were found to be severely anemic as compared to women who were moderately anemic (43.19%. Multiple logistic regression analysis of these factors showed that possibility of anemia is less in women who belong to rural area and it is highly significant. Analysis further showed significant association between anemia and type of diet and other factors like women having parity 1 and 4. Conclusion: The prevalence of anemia amongst the pregnant participants was very high. The socio-demographic and obstetrics factors were found to be associated with anemia. To prevent

    2004-01-01

    Hemolytic anemia due to immune function is one of the major causes of acquired hemolytic anemia. In recent years, as more is known about the immune system, these entities have become better understood and their treatment improved. In this section, we will discuss three areas in which this progress has been apparent. In Section I, Dr. Peter Hillmen outlines the recent findings in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH), relating the biochemical defect (the lack of glycosylphosphatidylinositol [GPI]-linked proteins on the cell surface) to the clinical manifestations, particularly hemolysis (and its effects) and thrombosis. He discusses the pathogenesis of the disorder in the face of marrow dysfunction insofar as it is known. His major emphasis is on innovative therapies that are designed to decrease the effectiveness of complement activation, since the lack of cellular modulation of this system is the primary cause of the pathology of the disease. He recounts his considerable experience with a humanized monoclonal antibody against C5, which has a remarkable effect in controlling the manifestations of the disease. Other means of controlling the action of complement include replacing the missing modulatory proteins on the cell surface; these studies are not as developed as the former agent. In Section II, Dr. Alan Schreiber describes the biochemistry, genetics, and function of the Fc gamma receptors and their role in the pathobiology of autoimmune hemolytic anemia and idiopathic thrombocytopenic purpura due to IgG antibodies. He outlines the complex varieties of these molecules, showing how they vary in genetic origin and in function. These variations can be related to three-dimensional topography, which is known in some detail. Liganding IgG results in the transduction of a signal through the tyrosine-based activation motif and Syk signaling. The role of these receptors in the pathogenesis of hematological diseases due to IgG antibodies is

  8. [A simple algorithm for anemia].

    Science.gov (United States)

    Egyed, Miklós

    2014-03-09

    The author presents a novel algorithm for anaemia based on the erythrocyte haemoglobin content. The scheme is based on the aberrations of erythropoiesis and not on the pathophysiology of anaemia. The hemoglobin content of one erytrocyte is between 28-35 picogram. Any disturbance in hemoglobin synthesis can lead to a lower than 28 picogram hemoglobin content of the erythrocyte which will lead to hypochromic anaemia. In contrary, disturbances of nucleic acid metabolism will result in a hemoglobin content greater than 36 picogram, and this will result in hyperchromic anaemia. Normochromic anemia, characterised by hemoglobin content of erythrocytes between 28 and 35 picogram, is the result of alteration in the proliferation of erythropoeisis. Based on these three categories of anaemia, a unique system can be constructed, which can be used as a model for basic laboratory investigations and work-up of anaemic patients.

    Sideroblastic anemias are caused by a diversity of hereditary, congenital, or acquired disorders. Criteria used in describing sideroblastic anemias vary widely among standard medical textbooks and even so have been imprecisely applied in the literature. Recent discoveries concerning the basic pathophysiologic mechanisms involving the molecular biology of nuclear and mitochondrial DNA, erythroid ALA synthase (ALAS-2), and iron transport have made the classification of sideroblastic anemias very complex. We recommend a more precise evaluation and documentation of the components that characterize the sideroblastic abnormality and propose an extended classification of the sideroblastic anemias.

    Full Text Available Un porcentaje considerable de pacientes presentan anemia post trasplante renal. Su origen es multifactorial y sus principales etiologías dependen de la etapa post trasplante que se considere. Estudiamos en un grupo de 134 pacientes los factores asociados con anemia tardía (6 meses post trasplante y sus implicaciones clínicas a mediano plazo. En el análisis de regresión múltiple, la duración de la oliguria post trasplante y el número de episodios de rechazo fueron las variables significativamente asociadas con esta complicación. La supervivencia del órgano mostró una diferencia significativa a los 36 meses entre los grupos (83% en los anémicos versus 96% de los no anémicos p < 0.01. No observamos diferencias en mortalidad o eventos cardiovasculares. Concluimos que la presencia de anemia al sexto mes post trasplante renal está independiente y significativamente asociada con factores que condicionan la masa renal funcionante que explicarían además la menor supervivencia del injerto renal observada en estos pacientes.

    2015-09-01

    The classification of autoimmune hemolytic anemias and the complement system are reviewed. In autoimmune hemolytic anemia of the warm antibody type, complement-mediated cell lysis is clinically relevant in a proportion of the patients but is hardly essential for hemolysis in most patients. Cold antibody-mediated autoimmune hemolytic anemias (primary cold agglutinin disease, secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria) are entirely complement-mediated disorders. In cold agglutinin disease, efficient therapies have been developed in order to target the pathogenic B-cell clone, but complement modulation remains promising in some clinical situations. No established therapy exists for secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria, and the possibility of therapeutic complement inhibition is interesting. Currently, complement modulation is not clinically documented in any autoimmune hemolytic anemia. The most relevant candidate drugs and possible target levels of action are discussed.

    Iron deficiency is more common in women due to uterine bleeding, which affects them throughout their fertile life. Additionally, iron needs increase physiologically during pregnancy and breastfeeding. Pregnant women therefore constitute one of the risk groups for iron deficiency. During the postpartum period, iron deficiency is the most common cause of anemia. Longer hospital stays and greater susceptibility to infections are potential consequences of postpartum anemia.

    Summary Iron deficiency and immune activation are the two most frequent causes of anemia, both of which are based on disturbances of iron homeostasis. Iron deficiency anemia results from a reduction of the body’s iron content due to blood loss, inadequate dietary iron intake, its malabsorption, or increased iron demand. Immune activation drives a diversion of iron fluxes from the erythropoietic bone marrow, where hemoglobinization takes place, to storage sites, particularly the mononuclear ph...

    Full Text Available Anemia of cancer (AC may contribute to cancer-related fatigue and impair quality of life. Improved understanding of the pathogenesis of AC could facilitate better treatment, but animal models to study AC are lacking. We characterized four syngeneic C57BL/6 mouse cancers that cause AC. Mice with two different rapidly-growing metastatic lung cancers developed the characteristic findings of anemia of inflammation (AI, with dramatically different degrees of anemia. Mice with rapidly-growing metastatic melanoma also developed a severe anemia by 14 days, with hematologic and inflammatory parameters similar to AI. Mice with a slow-growing peritoneal ovarian cancer developed an iron-deficiency anemia, likely secondary to chronically impaired nutrition and bleeding into the peritoneal cavity. Of the four models, hepcidin mRNA levels were increased only in the milder lung cancer model. Unlike in our model of systemic inflammation induced by heat-killed Brucella abortus, ablation of hepcidin in the ovarian cancer and the milder lung cancer mouse models did not affect the severity of anemia. Hepcidin-independent mechanisms play an important role in these murine models of AC.

    Full Text Available Iron-deficiency anemia is a common reason for referral to a gastroenterologist. In adult men and postmenopausal women, gastrointestinal tract pathology is often the cause of iron-deficiency anemia, so patients are frequently referred for endoscopic evaluation. Endoscopy may be costly and at times difficult for the patient. Therefore, physicians need to know what lesions can be identified reliably and, more importantly, the importance of ruling out life-threatening conditions such as occult malignancy. Over the past decade, a number of prospective studies have been completed that examined the yield of endoscopy in the investigation of iron-deficiency anemia. The present article provides a broad overview of iron-deficiency anemia, with particular emphasis on hematological diagnosis, etiology, the use of endoscopy in identifying lesions and iron-repletion therapy. Other clinical scenarios, including assessment of patients on anti-inflammatory or anticoagulation therapy and patients with bleeding of obscure origin, are also addressed. The present article provides a diagnostic algorithm to iron-deficiency anemia, which describes a more systematic manner in which to approach iron-deficiency anemia.

    Abstract Many patients with congestive heart failure (CHF) fail to respond to maximal CHF therapy and progress to end stage CHF with many hospitalizations, very poor quality of life, end stage renal failure, or die of cardiovascular complications within a short time. One factor that has generally been ignored in many of these patients is the fact that they are often anemic.The anemia is due mainly to renal failure but also to the inhibitory effects of cytokines on the bone marrow. Anemia itself may further worsen the cardiac function and make the patients resistant to standard CHF therapies. Indeed anemia has been associated with increased severity of CHF, increased hospitalization, worse cardiac function and functional class, higher doses of diuretics,worsening of renal function and reduced quality of life. In both controlled and uncontrolled studies the correction of the anemia with erythropoietin (EPO) and oral or Ⅳ iron is associated with improvement in all these parameters. EPO itself may also play a direct role in improving the heart unrelated to the improvement of the anemia. Anemia may also play a role in the worsening of coronary heart disease even without CHF.

  1. Mitochondrial iron metabolism and sideroblastic anemia.

    Science.gov (United States)

    Sheftel, Alex D; Richardson, Des R; Prchal, Josef; Ponka, Prem

    2009-01-01

    Sideroblastic anemias are a heterogeneous group of disorders, characterized by mitochondrial iron overload in developing red blood cells. The unifying characteristic of all sideroblastic anemias is the ring sideroblast, which is a pathological erythroid precursor containing excessive deposits of non-heme iron in mitochondria with perinuclear distribution creating a ring appearance. Sideroblastic anemias may be hereditary or acquired. Hereditary sideroblastic anemias are caused by defects in genes present on the X chromosome (mutations in the ALAS2, ABCB7, or GRLX5 gene), genes on autosomal chromosomes, or mitochondrial genes. Acquired sideroblastic anemias are either primary (refractory anemia with ring sideroblasts, RARS, representing one subtype of the myelodysplastic syndrome) or secondary due to some drugs, toxins, copper deficiency, or chronic neoplastic disease. The pathogenesis of mitochondrial iron loading in developing erythroblasts is diverse. Ring sideroblasts can develop as a result of a heme synthesis defect in erythroblasts (ALAS2 mutations), a defect in iron-sulfur cluster assembly, iron-sulfur protein precursor release from mitochondria (ABCB7 mutations), or by a defect in intracellular iron metabolism in erythroid cells (e.g. RARS).

    Full Text Available Patients with chronic kidney diseases (CKDs and cardiovascular diseases (CVDs present with various degree of anemia. Anemia has been associated with poor outcome in patients with CKD and CVD. CVD is the commonest cause of morbidity and mortality in patients with CKD. CKD causes anemia and CVD, and this rapidly deteriorates when anemia is not corrected. This triad of CVD, CKD, and anemia has been termed cardio-renal-anemia syndrome. The objec-tive of this study is to highlight the importance of cardio-renal-anemia syndrome, their relation-ship, and management. Three patients with various stages of CKD who presented with anemia and cardiovascular abnormalities are reported. The patients responded well to various interventional measures, with improvement in their clinical and laboratory parameters. Cardio-renal-anemia syndrome is an entity that should be identified. Early and appropriate intervention leads to better outcome.

    The most common hematologic complication of inflammatory bowel disease (IBD)--ulcerative colitis and Crohn's Disease is anemia. Anemia in patients with IBD may be a result of iron, vitamin B12 or folate deficiency; anemia of chronic disease and hemolytic anemia are other causes in these patients. Factors contributing to the development of anemia include chronic gastrointestinal blood loss, vitamin B12 malabsorption secondary to terminal ileitis, folate deficiency as a result of sulfasalazine therapy. Approximately 30% of patients with IBD have hemoglobin levels below 12 g/dl. The risk of developing anemia relates to disease activity, given that blood loss and inflammatory anemia are triggered by intestinal inflammation. In the management strategy of IBD patients with anemia it is important to distinguish between the different types of anemia in order to decide an appropriate manner of treatment.

    Iron deficiency and anemia are associated with impaired neurocognitive development and immune function in young children. Total body iron, calculated from serum ferritin and soluble transferrin receptor concentrations, and hemoglobin allow for monitoring of the iron and anemia status of children in the United States. The purpose of this analysis is to describe the prevalence of iron deficiency (ID), anemia, and iron deficiency anemia (IDA) among children 1–5 years using data from the 2007–2010 National Health and Nutrition Examination Survey (NHANES). Prevalence of ID, anemia, and IDA among children 1–5 years was 7.1% (5.5, 8.7), 3.2% (2.0, 4.3), and 1.1% (0.6, 1.7), respectively. The prevalence of both ID and anemia were higher among children 1–2 years (p < 0.05). In addition, 50% of anemic children 1–2 years were iron deficient. This analysis provides an update on the prevalence of ID, anemia, and IDA for a representative sample of US children. Our results suggest little change in these indicators over the past decade. Monitoring of ID and anemia is critical and prevention of ID in early childhood should remain a public health priority. PMID:27249004

    A 16-year-old boy who was diagnosed to have sickle cell anemia was referred to our center. The parental consanguinity, growth retardation and dysmorphic features prompted a search for possible Fanconi's Anemia (FA). The diepoxybutane (DEB) test was positive, confirming FA. The interaction of both diseases might account for his relatively mild phenotype in terms of both sickle cell anemia (or Hb S, HBB: c.20A > T) and FA. The high Hb F level that might be related to concomitant FA, may have caused a milder phenotype of sickle cell anemia, whereas nitric oxide (NO) depletion as a consequence of sickle cell anemia, may have caused a delay in the bone marrow failure of FA.

  14. Anemia in patients with diabetes mellitus

    2007-01-01

    Full Text Available Introduction: Anemia is more common and pronounced in patients with diabetic, than in patients with non-diabetic renal disease. While several factors contribute to its pathogenesis, the failure of the kidney to increase erythropoietin in response to falling hemoglobin appears to be the dominant factor. The most frequent complications of anemia in diabetic patients include decreased quality of life and work capacity and increased cardiovascular morbidity and mortality. Material and Methods: This cross-sectional multicenter study included a total of 539 patients with type I (~20% and type II diabetes (~80% classified into five stages according to the glomerular filtration rate. Results Diabetic nephropathy appears in stage I, and progresses in all patients to the stage V (p=0.045. The presence of anemia progressively increased from stage I to stage V (from 60% to 100%, p=0.008. Only 62% of patients with anemia were treated (mainly with iron and only 3.4% received erythropoietin treatment. Hypertension was present in 90% of patients in stage I and in 100% of patients in stage V nephropathy. The presence of heart failure increased from 0% (stage I to 51% (stage IV, p=0.03. Around 62% of patients were referred to a nephrologist, and according to the logistic regression model, renal failure and presence of anemia were significant predictors of patients' referral to nephrologist. Conclusion: In a primary care setting, anemia is a frequent finding, even in the very beginning of diabetic renal disease. Currently available guidelines for management of anemia are not followed; this may explain high percentage of patients with heart failure in pre-dialysis stage. Early referral to a nephrologist and regular follow-up by an endocrinologist and cardiologist are the best way for the prevention of diabetic complications and comorbidity.

    Full Text Available Over the past few years complete blood count (CBC by the automated hematology analyzers and microscopic examination of peripheral smear have complemented each other to provide a comprehensive report on patients’ blood sample. Numerous classifications for anemia have been established and the important parameters involved in the classifications are Hb, HCT, MCV, RDW, MCH, MCHC, reticulocytes and IRF. Many of these values are obtained only by automated heamatology analyzers. One histogram graph is worth 1000 numbers. A large collection of data, displayed as a visual image, can convey information with far more impact than the numbers alone. In hematology, these data take on several forms, one of which is the RBC histogram. Therefore a study of variation in RBC histograms in various anemias. Many times it is seen that histogram patterns show varying features when a simultaneous peripheral smear is reported. It is also seen that there are many limitations when manual peripheral smears reporting is done for example: peripheral smear reports are subjective, labor intensive and statistically unreliable. However microscopic peripheral smear examination also has their advantages. This study intends to create a guide to laboratory personnel and clinicians with sufficient accuracy to presumptively diagnose morphological classes of anemia directly from the automated hematology cell counter forms and correlate with morphological features of peripheral smear examination. OBJECTIVE: 1. The objective of the study is to know the utility and advantage of red cell histograms. 2. To study the automated histogram patterns along with morphological features noticed on peripheral smear examination. SOURCE OF DATA: All anemic patients from Central Diagnostic Laboratory of A.J.IMS. METHOD OF COLLECTION OF DATA: A total of about 100 patients were included in the study. Complete blood count including HB, TC, DC, Platelet count hematocrit value, RBC indices was obtained

    Full Text Available Due to the reduction in the number of red blood cells, caused by the immune system, the immune-mediated hemolytic anemia (IMHA is the most common disease among the hemolytic anemias and occurs more frequently in dogs (Nelson & Couto, 2010, wherein the most affected breeds are Cocker Spaniel, Poodle, Doberman and Collie (ETTINGER; FELDMAN 2004; THRALL et al 2007.. There is no pathognomonic sign for the diagnosis of the immune-mediated hemolytic anemia; however, laboratory findings show regenerative anemia, spherocytosis, positive results in Coombs' test and rarely, monocytes with hemosiderin or erythrocytes phagocytosis, but even with these findings, the primary and secondary IMHA can not be differentiate from each other. Differentiation can only be achieved when there is a deep investigation into the cause of the anemia. The IMHA therapeutics starts with the support treatment and follows with an immunosuppressive therapy. In relation to IMHA Mortality rates, the numbers range from 25% to 50% (Thrall, 2007, or above 70% (CARR; Panciera; Kidd, 2002.

    2009-10-01

    Inherited sideroblastic anemia comprises several rare anemias due to heterogeneous genetic lesions, all characterized by the presence of ringed sideroblasts in the bone marrow. This morphological aspect reflects abnormal mitochondrial iron utilization by the erythroid precursors. The most common X-linked sideroblastic anemia (XLSA), due to mutations of the first enzyme of the heme synthetic pathway, delta-aminolevulinic acid synthase 2 (ALAS2), has linked heme deficiency to mitochondrial iron accumulation. The identification of other genes, such as adenosine triphosphate (ATP) binding cassette B7 (ABCB7) and glutaredoxin 5 (GLRX5), has strengthened the role of iron sulfur cluster biogenesis in sideroblast formation and revealed a complex interplay between pathways of mitochondrial iron utilization and cytosolic iron sensing by the iron-regulatory proteins (IRPs). As recently occurred with the discovery of the SLC25A38-related sideroblastic anemia, the identification of the genes responsible for as yet uncharacterized forms will provide further insights into mitochondrial iron metabolism of erythroid cells and the pathophysiology of sideroblastic anemia.

    Full Text Available Objective: The aim of this study was to analyze the reticulocyte maturity indices (low, medium, and high fluorescence ratios in iron deficient 1- to 6-year-old children, and identify the prevalence of iron deficiency anemia in this population. Methods: The present study included 39 subjects, divided into two groups: control subjects (n = 33, and subjects with iron deficiency anemia (n = 6. The results were analyzed by Student's t-test for comparison of means. Differences were considered significant when two-tailed p-value < 0.05. Results: Subjects with iron deficiency anemia presented increases in the proportion of mean (10.3 ± 4.7% vs. 6.0 ± 3.4%; p-value = 0.003, and high fluorescence reticulocytes (2.3 ± 0.87% vs. 0.9 ± 0.9%; p-value = 0.03 compared to the control group. The prevalence of anemia in this population was 15% (n = 6. Conclusion: The indices related to immaturity of reticulocytes are higher in the presence of iron deficiency, thus demonstrating a deficiency in the raw material to form hemoglobin and are, therefore, possible early markers of iron deficiency and anemia. We emphasize the need to standardize these indices for use in clinical practice and lab test results.

    Iron is essential for life because it is indispensable for several biological reactions, such as oxygen transport, DNA synthesis, and cell proliferation. Over the past few years, our understanding of iron metabolism and its regulation has changed dramatically. New disorders of iron metabolism have emerged, and the role of iron as a cofactor in other disorders has begun to be recognized. The study of genetic conditions such as hemochromatosis and iron-refractory iron deficiency anemia (IRIDA) has provided crucial insights into the molecular mechanisms controlling iron homeostasis. In the future, these advances may be exploited to improve treatment of both genetic and acquired iron disorders. IRIDA is caused by mutations in TMPRSS6, the gene encoding matriptase-2, which downregulates hepcidin expression under conditions of iron deficiency. The typical features of this disorder are hypochromic, microcytic anemia with a very low mean corpuscular volume of erythrocytes, low transferrin saturation, no (or inadequate) response to oral iron, and only a partial response to parenteral iron. In contrast to classic iron deficiency anemia, serum ferritin levels are usually low-normal, and serum or urinary hepcidin levels are inappropriately high for the degree of anemia. Although the number of cases reported thus far in the literature does not exceed 100, this disorder is considered the most common of the "atypical" microcytic anemias. The aim of this review is to share the current knowledge on IRIDA and increase awareness in this field.

    Full Text Available Background: The aim of the present study was to find out the variation of pulmonary function parameters in different trimesters of pregnancy as well as variation according to severity of anemia in each trimester. Methods: The present case control study was carried out in the post-graduate department of obstetrics and gynecology, M.K.C.G. medical college and hospital, Berhampur, during the period from October 2012 to October 2013. This study entitled and ldquo;Pulmonary functions in pregnancy complicated with anemia and rdquo;, embodies the pulmonary functions of 60 anemic pregnant females (study group and 100 healthy pregnant females (control in different trimesters of pregnancy. The pulmonary function parameters, which were studied, are FVC, FEV1, FEV1/FVC, FEF25-75%, PEFR and MVV in both the study and control group. Results: Comparing the variation with advancing gestation in study and control, it was seen that FVC, FEV1, FEV1/FVC and FEF25-75% showed no significant alteration. With increasing severity of anemia compared to controls, FVC, FEV1, PEFR and MVV values reduce significantly. As FEF25-75% is not effort dependent, it shows no significant variation. Conclusion: Thus from this study, it can be concluded that moderate to severe anemia in pregnancy can adversely affect pulmonary functions. Hence nutritional anemia in early pregnancy should be provided with iron supplements in order to prevent adverse obstetric outcomes. [Int J Res Med Sci 2014; 2(4.000: 1431-1437

    Full Text Available La deficiencia de ácido fólico es la causa más frecuente de anemia en nuestro medio, después del síndrome anémico de origen ferropénico. Los folatos son componentes esenciales de la dieta humana y animal. En los alimentos el ácido fólico se encuentran principalmente en forma de poliglutamatos, formas que luego son hidrolizadas en el intestino delgado a nivel de yeyuno proximal. Es importante definir con exactitud el defecto vitamínico causante de la anemia megaloblástica, puesto que, la administración de vitamina B12 a pacientes con deficiencia de folatos puede corregir parcialmente las alteraciones megaloblásticas, sin embargo, la administración de ácido fólico a pacientes con deficiencia de cobalamina induce mejoría hematológica, pero empeora el cuadro neurológico. Las principales causas de anemia por deficiencia de folatos son un aporte dietético insuficiente, un aumento de los requerimientos, defectos de su absorción o interacción con fármacos. Los folatos, pueden verse perjudicados por la sensibilidad a la luz y a las altas temperaturas así como por su alta afinidad por el agua, lo que facilita su eliminación por lavado o cocción.Folic acid deficiency is the second most common cause of anemia in our environment, after anemia secondary to iron deficiency. Folates are essential components of human and animal diet. Folic acid is mainly in poliglutamate form, and it is hydrolyzed in the proximal jejunum. It is important to identify adequately the exact vitamin deficiency that causes megaloblastic anemia, because vitamin B12 administration in folate deficiency may correct partially megaloblasticalterations, but administration of folic acid in cobalamin deficient patients improves haematological parameters but deteriorates the neurological syndrome. Main causes of anemia secondary to folate deficiency are inadequate dietetic administration, increased requirements, impaired absorption and pharmacologic interactions

    Full Text Available Fanconi Anemia (FA is a rare autosomal recessive disorder affecting multiple body systems. The diagnosis is based on morphological abnormalities, hematological abnormalities (pancytopenia, macrocytic anemia and progressive bone marrow failure and genetic testing. However, genetic testing is complicated for FA because there are often many genes that are associated with its development, and large duplications, deletions or sequence variations are frequently observed in some of these genes. We report a patient with cytogenetically confirmed Fanconi anemia. Although morphological abnormalities were present from birth, diagnosis was suspected and made at 8 years of age when he presented to us. We report this case to create awareness among clinicians to use modern modalities of diagnosis for such cases in addition to the clinical assessment. This would further help these children reach their adulthood with good quality of life. [Int J Res Med Sci 2015; 3(4.000: 998-1001

    Objectives: Anemia is associated with increased mortality in patients with acute symptomatic pulmonary embolism (PE). The purpose of this study was to evaluate the feasibility of Hounsfield unit (HU) measurements on the single unenhanced trigger slice of pulmonary CT angiography scans for diagnosis of anemia. Material and Methods: 150 consecutive patients (median age 64 ± 16 years) with suspected PE underwent pulmonary CT angiography. Two radiologists, blinded to laboratory results, performed HU measurements in the single unenhanced trigger scan independently by region-based analysis (ROI). HU values from ascending and descending aorta and the calculated mean of both were correlated with serum hemoglobin levels. Inter- and intraobserver variability was determined for HU measurements, and ROC analysis was performed for diagnosis of anemia. Calculated linear models were used to assess formulas for estimation of hemoglobin levels from HU measurements. Results: HU measurements revealed high intra- and interrater reliability (ICC > 0.981 and ICC > 0.965, respectively). Calculated mean HU values showed a strong correlation with serum hemoglobin levels (r = 0.734), which allowed generation of different formulas for calculation of hemoglobin levels from HU measurements. ROC analyses confirmed a high sensitivity (80.4 for men; 91.3 for women) and specificity (84.0 for men; 84.9 for women) for diagnosing anemia. Conclusion: Diagnosis of anemia and quantification of hemoglobin levels upon a single unenhanced trigger scan of pulmonary CT angiography is feasible. We suggest disclosing the anemic state in the radiological report, independent of the presence of PE, since anemia carries increased risks of morbidity and mortality.

    Hereditary sideroblastic anemia (HSA) is a heterogeneous group of inherited anemic disorders which is characterized by the presence of ringed sideroblasts in the bone marrow, microcytic hypochromic anemia and typically its X-linked inheritance in patients. It has been shown that a deficiency of the erythroid-specific delta-aminolevulinate synthase (ALAS-E) activity is responsible for pyridoxine-responsive HSA in many patients, however, the pathogenesis of other types of HSA remains still unknown. In this article, recent evidence suggesting multiple causes for HSA is summarized and discussed.

    Aplastic anemia (AA) is a disease characterized by pancytopenia and hypoplastic bone marrow caused by the decrease of hematopoietic stem cells. The pathogenesis of AA is complex and involves an abnormal hematopoietic microenvironment, hematopoietic stem cell/progenitor cell deficiencies and immunity disorders. Survival in severe aplastic anemia (SAA) has markedly improved in the past 4 decades because of advances in hematopoietic stem cell transplantation, immunosuppressive and biologic drugs, and supportive care. Herein, we will update the main issues concern AA according to our literature review.

    The aim of the study was to evaluate the clinical efficiency of soluble transferrin receptor and transferrin receptor-ferritin index (sTfR/logF) in the diagnosis of iron deficiency anemia, as well as the differential diagnosis of iron deficiency anemia and anemia in rheumatoid arthritis. The study included 96 patients with anemia and 61 healthy volunteers as a control group. In healthy subjects there were no significant sex and age differences in the parameters tested. The study results showed these parameters to be reliable in the diagnosis of iron deficiency anemia, as well as in the differential diagnosis of iron deficiency anemia and anemia of chronic disease. The results indicate that sTfR/logF could be used to help differentiate coexisting iron deficiency in patients with anemia of chronic disease. Receiver operating characteristic analysis showed a higher discriminating power of transferrin receptor-ferritin index vs. soluble transferrin receptor in the diagnosis of iron deficiency anemia, as well as in the differential diagnosis between iron deficiency anemia and anemia of chronic disease. In patients with anemia in rheumatoid arthritis, the parameters tested showed no significant differences with respect to C-reactive protein concentration. These results suggested that the parameters tested are not affected by acute or chronic inflammatory disease.

    X-linked sideroblastic anemia (XLSA) is a rare hereditary disorder that typically manifests in males as microcytic anemia. Here, we report a family with XLSA that affects females and manifests as macrocytic anemia. The proband was a Japanese woman harboring a heterozygous mutation c.679C>T in the ALAS2 gene. This mutation causes the amino acid substitution R227C, which disrupts the enzymatic activity of erythroid-specific δ-aminolevulinic acid synthase. The mutation was not detected in the ALAS2 complementary DNA from peripheral blood red blood cells of the proband, indicating that the cells were mostly derived from erythroblasts expressing wild-type ALAS2. The proband's mother, who had been diagnosed with myelodysplastic syndrome, also had XLSA with the same mutation. Clinicians should be aware that XLSA can occur not only in males but also in females, in whom it manifests as macrocytic anemia.

    A 59-year-old man was orally administered rabeprazole, a proton pump inhibitor (PPI), for gastroesophageal reflux disease, after which he gradually developed iron-deficiency anemia. The anemia did not improve following the administration of ferrous fumarate, and endoscopic screening of the entire gastrointestinal tract, including the small intestine, did not reveal any findings indicating the cause of the anemia. The patient was then switched from rabeprazole to famotidine and the anemia was cured within three months. There is much debate as to whether the long-term use of PPIs causes iron-deficiency. However, this case strongly suggests that PPIs can induce iron-deficiency anemia.

    Hemolytic anemia has been reported to occur in the setting of aortic stenosis and prosthetic heart valves, but much more rarely in association with obstructive hypertrophic cardiomyopathy (HC). Of the few descriptions of hemolytic anemia secondary to HC, all but one case involved bacterial endocarditis contributing to left ventricular outflow tract obstruction. We present the case of a 67-year-old man with recurrent hemolytic anemia and HC, without infective endocarditis. Attempts at iron repletion and augmentation of beta-blocker therapy proved his anemia to be refractory to medical management. Ventricular septal myectomy led to the resolution of hemolysis, anemia, and its coexisting symptoms. PMID:26424952

    Anemia is a prevalent disease with multiple possible etiologies and resultant complications. Iron deficiency anemia is a common cause of anemia and is typically due to insufficient intake, poor absorption, or overt or occult blood loss. Distinguishing iron deficiency from other causes of anemia is integral to initiating the appropriate treatment. In addition, identifying the underlying cause of iron deficiency is also necessary to help guide management of these patients. We review the key components to an evidence-based, cost-conscious evaluation of suspected iron deficiency anemia.

    Autoimmune hemolytic anemia (AIHA) is diagnosed in the presence of anemia, usually macrocytic and of variable intensity, reticulocytosis, and a positive direct and/or indirect antiglobulin test, after ruling out other types of hemolytic anemia. A positive direct antiglobulin test alone is not sufficient to diagnose AIHA and may be positive in many patients without anemia or negative in some patients with AIHA. AIHA may be classified into two major categories according to the optimal temperature of antibody activity: warm-reacting autoantibodies (usually IgG) optimal around 37 degrees C and cold-reacting autoantibodies, optimal at 4 degrees C (usually IgM). This classification guides the selection of tests and treatment. AIHA is widely reported to be associated with a variety of other diseases, although these associations are often fortuitous. A minimal set of useful investigations is appropriate since AIHA may be secondary to viral infections, lymphoid malignancies, or autoimmune disorders such as lupus. Transfusion should remain rare in AHAI, but close contact with the transfusion service is necessary if it is to succeed. As for many autoimmune and/or systemic diseases, numerous types of treatment have been proposed but have not been validated in controlled multicenter studies. These are necessary to improve the management of these rare disorders.

    Hereditary sideroblastic anemia is a very rare disease recessive and X-linked that affect heme biosynthesis by deficit or decreased of delta aminolevulinic acid synthase (ALAS) activity. We report a case of a six-month-old boy, admitted in the hospital for anemic syndrome. The hemogram showed anemia (hemoglobin: 4.5 g/dL), frankly hypochronic microcytic and a regenerated (mean corpuscular hemoglobin concentration: 26 g/dL, mean cell volume: 53 fl, reticulocytes: 10 x 10(9)/L) with red cells morphologic disorders in smears (anisopoikylocytosis) without attack of the other lineages; white blood cells: 11 x 10(9)/L (neutrophils: 64% and lymphocytes: 35%); platelets: 350 x 10(9)/L. Examination of bone marrow showed an important erythroid hyperplasia (about 69%) with dyserythropoiesis. Perls stain revealed intense siderosis with 90% of ringed sideroblasts and a large number of siderocytes. Exploration of ALAS2 and ABC7 genes on the DNA of the infant was not found abnormalities. Treatment with pyridoxine corrects moderately the anemia. By the way, we proposed to remind that iron deficiency, inflammatory syndrome and thalassemia are the common microcytic anemia. However, it's mandatory to explore other causes if diagnosis is not solved.

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD. PMID:26301120

    Hysterectomy is the second-most-common surgical procedure among premenopausal women. The conditions that lead to the need for a hysterectomy often are accompanied by chronic blood loss that can lead to anemia. Moreover, hysterectomy and myomectomy may result in significant blood loss, which exacerbates the anemia. The presence of fatigue associated with anemia has a substantially negative impact on quality of life and the ability to perform activities of daily living. Options for alleviating perioperative anemia include minimizing surgical blood loss, blood transfusion, supplementation with hematinics, such as iron and folic acid, and treatment with recombinant human erythropoietin. Treating preoperative anemia is expected to help correct anemia prior to surgery and may have a positive impact on anemia-related symptoms and surgical outcomes.

    A 62 year old male (R.H.) presented with a mild anemia (Hb 11-12 gm%) and a history of multiple hemorrhagic episodes. The marrow had 40-50% sideroblasts. Marrow chromosomes were normal. His wife was hematologically normal, while one daughter, age 30 years, had a sideroblastic anemia (Hb 11-12 gm%) with 40-50% sideroblasts in the marrow. Her anemia was first noted at age 15 years. Administration of vitamin B6 did not correct the anemia in either the father or daughter. Platelet abnormalities inherited jointly with this disorder are described for the first time. Both R.H. and his daughter had prolonged bleeding times, with normal PTT, PT times, fVIII:C, fVIII:Ag levels, and vWF multimers, which may rule out a von Willebrand's disease. They have normal platelet numbers but abnormally low platelet adhesiveness and greatly depressed ADP, collagen, and epinephrine responsiveness. Response to ristocetin was in the low normal range, and aggregation with thrombin was normal. While desmopressin completely normalized R.H.'s bleeding time, none of these platelet parameters were improved. No differences in the SDS PAGE protein patterns of RH platelets could be detected in comparison to normal samples. His platelets took up and released serotonin (5HT) normally, and electron micrographs defined no morphological abnormalities. However, no ATP was released from platelets activated with collagen, and when followed by thrombin about fourfold greater ATP was released by control platelets as compared to RH platelets. The dense granule fraction derived from RH platelets contained about 20% the level of ATP, 40% the level of ADP, and 50% the level of 5HT detected in a normal sample. The results indicate that the bleeding disorder is related to a non-classical heritable storage pool defect. The connection between the inherited sideroblastic anemia and platelet defects is obscure.

    Thyroid hormones stimulate directly or indirectly growth of erythroid colonies through erythropoietin. Anemia is often the first sign of hypothyroidism. Hypothyroidism can cause a wide variety of anemic disorders. Numerous mechanisms are involved in the pathogenesis of these anemias that can be microcytic, macrocytic and normocytic. We designed this study to investigate the anemia frequency and if present, etiology of anemia in hypothyroid patients. 100 patients with overt hypothyroid, 100 patients with subclinical hypothyroid, and 200 healthy controls were enrolled in this study. Overt hypothyroidism diagnosis is done when elevated TSH and low levels of free T4 and/or free T3 have been observed. Subclinical hypothyroidism is defined as elevated serum TSH with normal free T(4) and free T(3) levels. Peripheral smears of the anemic patients were examined. Anemia prevalence was 43% in the overt hypothyroid group, 39% in the subclinical hypothyroid group, and 26% in the control group (p=0.0003 and p=0.021 respectively related to controls). Thus, the frequency of anemia in subclinical hypothyroidism is as high as that in overt hypothyroidism. There was no difference between the hypothyroid groups in terms of anemia. Vitamin B12, Fe, and folic acid were similar between these groups. According to our findings, anemia of chronic disease is the most common type of anemia in hypothyroid patients. Suspicion of hypothyroidism should be considered in anemias with uncertain etiology.

    Full Text Available In many elderly patients with anemia, a specific cause cannot be identified. This study investigates whether erythropoietin levels are inappropriately low in these cases of "anemia of unknown etiology" and whether this trend persists after accounting for confounders.This study includes all anemic patients over 60 years old who had erythropoietin measured between 2005 and 2013 at a single center. Three independent reviewers used defined criteria to assign each patient's anemia to one of ten etiologies: chronic kidney disease, iron deficiency, chronic disease, confirmed myelodysplastic syndrome (MDS, suspected MDS, vitamin B12 deficiency, folate deficiency, anemia of unknown etiology, other etiology, or multifactorial etiology. Iron deficiency anemia served as the comparison group in all analyses. We used linear regression to model the relationship between erythropoietin and the presence of each etiology, sequentially adding terms to the model to account for the hemoglobin concentration, estimated glomerular filtration rate (eGFR and Charlson Comorbidity Index.A total of 570 patients met the inclusion criteria. Linear regression analysis showed that erythropoietin levels in chronic kidney disease, anemia of chronic disease and anemia of unknown etiology were lower by 48%, 46% and 27%, respectively, compared to iron deficiency anemia even after adjusting for hemoglobin, eGFR and comorbidities.We have shown that erythropoietin levels are inappropriately low in anemia of unknown etiology, even after adjusting for confounders. This suggests that decreased erythropoietin production may play a key role in the pathogenesis of anemia of unknown etiology.

    Cancer related anemia (CRA) adversely affects patient Quality of Life (QoL) and overall survival. We prospectively studied the prevalence, etiology and the impact of anemia on QoL in 218 Indian cancer patients attending a tertiary referral hospital. The study used the sTfR/log Ferritin index to detect iron deficiency anemia and assessed patient QoL using the Functional Assessment of Cancer Therapy-Anemia (FACT-An) tool, standardized for language. Mean patient age was 51±13 years and 60% were female. The prevalence of cancer related anemia in this setting was 64% (n = 139). As expected, plasma ferritin did not differ significantly between anemic (n = 121) and non-anemic cancer patients (n = 73). In contrast, plasma sTfR levels were significantly higher in anemic cancer patients compared to non-anemic cancer patients (31 nmol/L vs. 24 nmol/L, p = 0.002). Among anemic cancer patients, using the sTfR/log Ferritin index, we found that 60% (n = 83) had iron deficiency anemia (IDA). Interestingly, plasma sTfR levels were significantly higher in cancer patients with CRA+IDA (n = 83) compared with patients having CRA (n = 38) alone (39 nmol/L vs. 20 nmol/L, p<0.001). There was a significant linear correlation between Hb and QoL (Spearman ρ = 0.21; p = 0.001) and multivariate regression analysis revealed that every gram rise in Hb was accompanied by a 3.1 unit increase in the QoL score (95% CI = 0.19–5.33; p = 0.003). The high prevalence of anemia in cancer patients, a major portion of which is due to iron deficiency anemia, the availability of sensitive and specific biomarkers of iron status to detect IDA superimposed on anemia of inflammation, suggests an urgent need to diagnose and treat such patients. Despite the potential negative consequences of increasing metabolically available plasma iron in cancer, our clinical data suggest that detecting and treating IDA in anemic cancer patients will have important consequences to their QoL and overall survival.

    Full Text Available INTRODUCTION: Anemia is defined as haemoglobin level in the blood below the lower extreme of the normal range for the age and sex of the individual. According to WHO, in developing countries the prevalence of anemia among pregnant women averages 60%, ranging between 35 to 100% among different regions of the world. A hemoglobin concentration below 11.0g/dl or packed cell volume (PCV of less than 33.0% is regarded as anemia during pregnancy by the WHO. It occurs in 40 - 80% of the pregnant women. Iron and folic acid defici encies, malaria, intestinal parasitic infections and hemoglobinopathies are the principal causes of anemia in pregnancy. Predisposing factors include young age, grand multiparity, low socioeconomic status, illiteracy, ignorance and short intervals of pregn ancy. AIM AND OBJECTIVES: 1. To study various patterns of anemia in pregnant women having haemoglobin level < 11 gm%. 2. To determine the most common pattern of anemia in pregnancy based on red cell morphology. MATERIALS AND METHODS: This study is a prospe ctive study over a period of one year from September 2014 to August 2015 in the department of pathology, Andhra medical college, Visakhapatnam . The study was conducted on 120 pregnant women whose haemoglobin level is < 11 gm/dl. All the haemotological parameters & peripheral blood smear stained by Leishman’s stain were evaluated. Complete clinical & obstetric history was recorded. Socioeconomic status was also noted. RESULTS: Out of 120 cases of anemia, we found 47 patie nts (39.1% having dimorphic anemia, 36(30% – microcytic hypochromic anemia, 23(19.1% - normocytic hypochromic anemia, 11(9.16% - sickle cell anemia and 1(0.83% case of pancytopenia.

    Full Text Available James W Swann,1 Barbara J Skelly2 1Queen Mother Hospital for Animals, The Royal Veterinary College, Hatfield, Hertfordshire, 2Department of Veterinary Medicine, University of Cambridge, Cambridge, UK Abstract: Immune-mediated hemolytic anemia is one of the most common manifestations of canine immune-mediated disease, yet treatment regimens remain nonstandardized and, in some cases, controversial. The main reason for this, as for most diseases in veterinary medicine, is the lack of large-scale placebo-controlled trials so that the efficacy of one treatment over another can be established. Most of the evidence used for treatment comes from retrospective studies and from personal preference and experience, and because of this, treatment regimens tend to vary among institutions and individual clinicians. Management of immune-mediated hemolytic anemia includes immunosuppression, thromboprophylaxis, and supportive care measures to help prevent and treat concurrent conditions.

  14. Iron deficiency decreases hemolysis in sickle cell anemia Anemia ferropriva diminui hemólise em anemia falciforme

    2009-02-01

    Full Text Available A woman with homozygous sickle cell disease developed severe iron deficiency due to long-standing uterine bleeding. At this point, the serum lactic dehydrogenase level was normal and the reticulocyte count was only minimally elevated. This suggested that the low red cell hemoglobin concentration that resulted from iron deficiency also decreased Hb S polymerization and lowered the hemolytic rate. Iron replacement led first to a substantially improved hemoglobin concentration with only a minimal increase in the hemolytic rate and secondarily to a modest further improvement in the hemoglobin concentration and a marked increase in the hemolytic rate. The hematologic changes observed in this patient, and those in other iron deficient sickle cell patients reported in the literature, suggest that it may be appropriate to consider the induction of an intermediate iron deficient stage as experimental treatment in adult sickle cell patients.Uma mulher com anemia falciforme homozigose para a Hb S evoluiu com anemia ferropriva grave devido a sangramento uterino prolongado. A dosagem de dehidrogenase lática era normal e a contagem de reticulócitos estava levemente aumentada. Isto sugere que concentrações baixas de hemoglobina, que resulta de anemia ferropriva, também diminuem a polimeração de Hb S e reduz a taxa de hemólise. O complemento de ferro levou, primeiramente, a uma concentração substancialmente maior de hemoglobina com apenas um aumento mínimo na taxa hemolítica e subsequentemente a um aumento leve adicional na concentração da hemoglobina e um aumento notável na taxa hemolítica. As mudanças hematológicas observadas nesta paciente e aquelas em outras pacientes com anemia falciforme e também deficientes de ferro relatadas na literatura sugerem que pode ser interessante considerar a indução de deficiência de ferro como tratamento experimental em pacientes adultos com anemia falciforme.

    Background In Korea, the prevalence of anemia and iron deficiency anemia (IDA) among older infants and young children remains high. To detect IDA early and to reduce its adverse impact, we assessed the characteristics of infants and young children who had IDA or were at risk of developing IDA, or who exhibited characteristics associated with severe anemia. Methods Among the 1,782 IDA-affected children aged 6 months to 18 years who visited the hospital, we retrospectively analyzed the medical records and laboratory data of 1,330 IDA-affected children aged 6–23 months who were diagnosed between 1996 and 2013. We excluded patients with a C-reactive protein level ≥5 mg/dL. Results IDA was predominant in boys (2.14:1) during infancy and early childhood. The peak IDA incidence was noted among infants aged 9–12 months. Only 7% patients exhibited symptoms of IDA, while 23.6% patients with severe IDA demonstrated classic symptoms/signs of IDA. Low birth weight (LBW) infants with IDA demonstrated low adherence to iron supplementation. In a multivariate analysis, prolonged breastfeeding without iron fortification (odds ratio [OR] 5.70), and a LBW (OR 6.49) were identified as risk factors of severe anemia. Conclusion LBW infants need more attention in order to increase their adherence to iron supplementation. For the early detection of IDA, nutritional status of all infants, and iron batteries of high-risk infants (LBW infants, infants with prolonged breastfeeding, picky eaters, and/or infants with the presence of IDA symptoms) should be evaluated at their health screening visits.

Therefore the aim of the present study was the effect of vitamin C supplement and maximal and submaximal swimming exercise on anemia in without iron deficiency rats.Methods: For this purpose, 60 male wistar rats (6-8 week age and 170 -190 g weight were divided into 6 groups: 1: Control rats (Con, n=10 2: Vitamin C supplementation (Con+C, n=10 3: Submaximal swimming (S, n=10 4: Submaximal swimming + Vitamin C (S+C, n=10 5: Maximal swimming (M, n=10 and 6: Maximal swimming and Vitamin C (M+C, n=10. Swimming training lasted for 10 weeks (5 day per week for 60 min day−1. Rats in the vitamin C-treated groups drank water containing 0.1% Vitamin C. Submaximal and maximal exercise training carried out for 1and 3 hours per session. 5 cc blood sample was take from vena cava vein for the determine serum levels of anemia indices (serum iron, Ferritin, TIBC،Hct, Hb, reticulocytes, RBC, MCV، MCH، MCHC.Results: Statistical analysis showed that the serum iron, ferritin, TIBC and MCV were not significantly different between groups. Reticulocytes in Con+C and S+C groups decreased significantly. Also, RBC and Hct decreased significantly in S and S+C groups, but Hb increased in S group in compared with the other groups. In this regard, MCH and MCHC significantly increased in S and S+C groups.Conclusion: 10 week submaximal swimming exercise increased Hb, MCH and MCHC but have no effect on serum iron, Ferritin and TIBC in without iron deficiency rats. On the other hand, high intensity swimming training had no effect on anemia indices. 0.1 % Vitamin C supplement and swimming training despite an insignificant increased in ferritin has not effected on iron status in without iron deficiency rats.

    Anemia represents a substantial problem for children living in areas with limited resources and significant parasite burden. We performed a cross-sectional study of 254 Kenyan preschool- and early school-age children in a setting endemic for multiple chronic parasitic infections to explore mechanisms of their anemia. Complete venous blood cell counts revealed a high prevalence of local childhood anemia (79%). Evaluating the potential links between low hemoglobin and socioeconomic factors, nutritional status, hemoglobinopathy, and/or parasite infection, we identified age anemia. A total of 130/155 (84%) of anemic children with iron studies had evidence of iron-deficiency anemia (IDA), 16% had non-IDA; 50/52 of additionally tested anemic children met soluble transferrin-receptor (sTfR) criteria for combined anemia of inflammation (AI) with IDA. Children in the youngest age group had the greatest odds of iron deficiency (OR: 10.0, 95% CI: 3.9, 26). Although older children aged 9-11 years had less anemia, they had more detectable malaria, Schistosoma infection, hookworm, and proportionately more non-IDA. Anemia in this setting appears multifactorial such that chronic inflammation and iron deficiency need to be addressed together as part of integrated management of childhood anemia.

    Anemia, the most common hematologic abnormality, is a reduction in the concentration of erythrocytes or hemoglobin in blood. The two most common causes of anemia in pregnancy and the puerperium are iron deficiency and acute blood loss. Iron requirements increase during pregnancy, and a failure to maintain sufficient levels of iron may result in adverse maternal-fetal consequences. The purpose of this document is to provide a brief overview of the causes of anemia in pregnancy, review iron requirements, and provide recommendations for screening and clinical management of anemia during pregnancy.

    Occupational lead exposure can cause anemia at blood lead levels >50 microg/dl, as high as rarely occurs in industrialized countries nowadays. Whereas other forms of anemia are fairly probable to be found in lead exposed workers, especially in areas highly endemicfor extraoccupational anemias, such as beta thalassemia and iron deficiency anemia. The etiology of anemias has to be correctly defined in order to assess suitable therapeutical approaches and medicolegal consequences. The objective of this study is to verify in male lead exposed workers whether an accurate evaluation of hemocromocytometric parameters and of usual biological indices of lead exposure and effect on heme can differentiate the most common forms of anemia in Southern Italy. 68 workers occupationally exposed to low to moderate lead doses were studied and 59 workers of an alimentary plant have been taken as control group. On venous blood samples collected from these workers a complete hemocromocytometric test was performed and blood lead and erythrocytic zincoprotoporphyrin were determined. Anemia (Hb lead exposed workers and in a nonexposed worker. The reasoned evaluation of laboratory parameters led to identify among lead exposed workers four subjects with high probability of beta-thalassemic trait and two with lead poisoning anemia. Moreover a diagnostic algorithm was developed based on literature that seems to be able to discriminate lead poisoning from other causes of anemia in lead exposed workers in this study.

    Lead pollution is a substantial problem in developing countries such as India. The US Centers for Disease Control and Prevention has defined an elevated blood lead level in children as > or = 10 microg/dl, on the basis of neurologic toxicity. The US Environmental Protection Agency suggests a threshold lead level of 20-40 microg/dl for risk of childhood anemia, but there is little information relating lead levels anemia. Therefore, the authors examined the association between lead levels as low as 10 mug/dl and anemia in Indian children under 3 years of age. Anemia was divided into categories of mild (hemoglobin level 10-10.9 g/dl), moderate (hemoglobin level 8-9.9 g/dl), and severe (hemoglobin level Lead levels lead levels > or = 10-19.9 microg/dl and 97 (9%) had levels > or = 20 microg/dl. After adjustment for child's age, duration of breastfeeding, standard of living, parent's education, father's occupation, maternal anemia, and number of children in the immediate family, children with lead levels > or = 10 microg/dl were 1.3 (95% confidence interval: 1.0, 1.7) times as likely to have moderate anemia as children with lead levels anemia was 1.7 (95% confidence interval: 1.1, 2.6). Health agencies in India should note the association of elevated blood lead levels with anemia and make further efforts to curb lead pollution and childhood anemia.

    Despite its high prevalence, anemia often does not receive proper clinical attention, and detection, evaluation, and management of iron deficiency anemia and iron-restricted erythropoiesis can possibly be an unmet medical need. A multidisciplinary panel of clinicians with expertise in anemia management convened and reviewed recent published data on prevalence, etiology, and health implications of anemia as well as current therapeutic options and available guidelines on management of anemia across various patient populations and made recommendations on the detection, diagnostic approach, and management of anemia. The available evidence confirms that the prevalence of anemia is high across all populations, especially in hospitalized patients. Anemia is associated with worse clinical outcomes including longer length of hospital stay, diminished quality of life, and increased risk of morbidity and mortality, and it is a modifiable risk factor of allogeneic blood transfusion with its own inherent risks. Iron deficiency is usually present in anemic patients. An algorithm for detection and management of anemia was discussed, which incorporated iron study (with primary emphasis on transferrin saturation), serum creatinine and glomerular filtration rate, and vitamin B12 and folic acid measurements. Management strategies included iron therapy (oral or intravenous), erythropoiesis-stimulating agents, and referral as needed.

    In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells. A 16-year-old with sickle cell disease receiving chronic transfusion of modified intensity (goal to maintain hemoglobin Sanemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    2012-01-01

    Full Text Available Anemia of any degree is recognized as a significant independent contributor to morbidity, mortality, and frailty in elderly patients. Among the broad types of anemia in the elderly a peculiar role seems to be played by the anemia associated with chronic inflammation, which remains the most complex form of anemia to treat. The origin of this nonspecific inflammation in the elderly has not yet been clarified. It seems more plausible that the oxidative stress that accompanies ageing is the real cause of chronic inflammation of the elderly and that the same oxidative stress is actually a major cause of this anemia. The erythropoietic agents have the potential to play a therapeutic role in this patient population. Despite some promising results, rHuEPO does not have a specific indication for the treatment of anemia in the elderly. Moreover, concerns about their side effects have spurred the search for alternatives. Considering the etiopathogenetic mechanisms of anemia of inflammation in the elderly population, an integrated nutritional/dietetic approach with nutraceuticals that can manipulate oxidative stress and related inflammation may prevent the onset of this anemia and its negative impact on patients’ performance and quality of life.

    Full Text Available Introduction. Iron deficiency anemia and thalassemia are the most common causes of microcytic anemia. Powerful statistical computer programming enables sensitive discriminant analyses to aid in the diagnosis. We aimed at investigating the performance of the multiple discriminant analysis (MDA to the differential diagnosis of microcytic anemia. Methods. The training group was composed of 200 β-thalassemia carriers, 65 α-thalassemia carriers, 170 iron deficiency anemia (IDA, and 45 mixed cases of thalassemia and acute phase response or iron deficiency. A set of potential predictor parameters that could detect differences among groups were selected: Red Blood Cells (RBC, hemoglobin (Hb, mean cell volume (MCV, mean cell hemoglobin (MCH, and RBC distribution width (RDW. The functions obtained with MDA analysis were applied to a set of 628 consecutive patients with microcytic anemia. Results. For classifying patients into two groups (genetic anemia and acquired anemia, only one function was needed; 87.9% β-thalassemia carriers, and 83.3% α-thalassemia carriers, and 72.1% in the mixed group were correctly classified. Conclusion. Linear discriminant functions based on hemogram data can aid in differentiating between IDA and thalassemia, so samples can be efficiently selected for further analysis to confirm the presence of genetic anemia.

    Full Text Available Background. Anemia is a common condition in the elderly and a significant risk factor for increased morbidity and mortality, reducing not only functional capacity and mobility but also quality of life. Currently, few data are available regarding anemia in hospitalized geriatric patients. Our retrospective study investigated epidemiology and causes of anemia in 405 hospitalized geriatric patients. Methods. Data analysis was performed using laboratory parameters determined during routine hospital admission procedures (hemoglobin, ferritin, transferrin saturation, C-reactive protein, vitamin B12, folic acid, and creatinine in addition to medical history and demographics. Results. Anemia affected approximately two-thirds of subjects. Of 386 patients with recorded hemoglobin values, 66.3% were anemic according to WHO criteria, mostly (85.1% in a mild form. Anemia was primarily due to iron deficiency (65%, frequently due to underlying chronic infection (62.1%, or of mixed etiology involving a combination of chronic disease and iron deficiency, with absolute iron deficiency playing a comparatively minor role. Conclusion. Greater awareness of anemia in the elderly is warranted due to its high prevalence and negative effect on outcomes, hospitalization duration, and mortality. Geriatric patients should be routinely screened for anemia and etiological causes of anemia individually assessed to allow timely initiation of appropriate therapy.

    As a common problem in long-term care facilities (LTCFs), anemia affects 25–63% of the elderly. The aim of the present study was to describe the prevalence and characteristics of anemia and its associated factors in the institutionalized elderly. The cross-sectional study was carried out with three hundred thirteen individuals aged ≥ 60 years, of both genders, living in long-term care facilities for the elderly in Salvador, Bahia, Brazil. Poisson regression (PR) with robust variance estimates was used to assess the factors related to anemia. The prevalence of anemia was 38%. Mild anemia was predominant in both genders (male: 26.8%; female: 21.1%), as normocytic and normochromic anemia, with no anisocytosis (69.75%). Anemia was associated with thinness (PR: 1.68; 95% CI: 1.04–2.72) and with moderate (PR: 1.98; 95% CI: 1.07–3.63) and total (PR: 2.61; 95% CI: 1.34–5.07) dependence in the final model. Severe dependence exhibited borderline significance (PR: 1.94; 95% CI: 1.00–3.77). The prevalence of anemia was high in the institutionalized elderly in both genders, with characteristics suggesting chronic diseases as the causal factor, and the frequency of occurrence was higher in thinness elderly with moderate to total dependence.

    Iron deficiency anemia is a hypochromic anemia in which hemoglobin poor synthesis is due to a decrease in the amount of iron in the body. The decrease of iron quantity has many causes: insufficient intake of aliments rich in iron (meat, viscera, green vegetables), increased necessities during growth period, pregnancy, erythrocytes hyperregeneration, high-performance sportsmen, increased loss by digestive way, genito-urinary way, respiratory, hemorrhagic syndromes. Clinically, symptoms and signs specific to all types of anemia and those specific to lack of iron occur besides the symptoms and signs of the underlying disease: atrophic glositis, angular stomatitis, sideropenic dysphagia, pica, skin and nails changes. Laboratory investigations useful for diagnosis are: microcytic, hypochromic anemia, decreased serum iron level, total capacity of iron binding increased, medullar iron store absent, good response to iron therapy. Ferro-Folgamma is one of the most indicated medicines in iron deficiency anemia. Due to its components this medicine has many indications: insufficient alimentary intake concerning iron, folic acid, B12 vitamin, vegetarian alimentation, increased needs during growth period, iron deficiency anaemia secondary to chronic hemorrhages, malnutrition, anemias associated with chronic alcohol intake, preventive treatment of iron deficiency anemia and megaloblastic anemia during pregnancy and lactation.

    Isabela Martins Benseñor

    Full Text Available CONTEXT AND OBJECTIVES: Quantification of clinical signs such as the presence or absence of pallor at clinical examination is a key step for making diagnoses. The aim was, firstly, to evaluate two methods for anemia diagnosis by physical examination: four-level evaluation (crosses method: +/++/+++/++++ and estimated hemoglobin values, both performed by medical students and staff physicians; and secondly, to investigate whether there was any improvement in assessment accuracy according to the number of years in clinical practice. DESIGN AND SETTING: Forty-four randomly selected physicians and medical students in a tertiary care teaching hospital completed a physical examination on five patients with mild to severe anemia. METHODS: The observers used four-level evaluation and also predicted the hemoglobin level. Both methods were compared with the real hemoglobin value as the gold standard. RESULTS: The mean estimated hemoglobin value correlated better with the real hemoglobin values than did the four-level evaluation method, for attending physicians, residents and students (Spearman's correlation coefficients, respectively: 1.0, 1.0 and 0.9 for guessed hemoglobin and -0.8, -0.8 and -0.7 for the four-level evaluation method. There were no differences in the mean "guessed" hemoglobin values from attending physicians, residents and students. However, the correlation between guessed hemoglobin value and the four-level method was positive for attending physicians, thus suggesting some kind of improvement with time (p = 0.04. CONCLUSIONS: This study showed that estimated hemoglobin was more accurate than evaluation by the four-level method. The number of years in clinical practice did not improve the accuracy of clinical examination for anemia.

  12. Iron, anemia and hepcidin in malaria

    Directory of Open Access Journals (Sweden)

    Natasha eSpottiswoode

    2014-05-01

    Full Text Available Malaria and iron have a complex but important relationship. Plasmodium proliferation requires iron, both during the clinically silent liver stage of growth and in the disease-associated phase of erythrocyte infection. Precisely how the protozoan acquires its iron from its mammalian host remains unclear, but iron chelators can inhibit pathogen growth in vitro and in animal models. In humans, iron deficiency appears to protect against severe malaria, while iron supplementation increases risks of infection and disease. Malaria itself causes profound disturbances in physiological iron distribution and utilization, through mechanisms that include hemolysis, release of heme, dyserythropoiesis, anemia, deposition of iron in macrophages, and inhibition of dietary iron absorption. These effects have significant consequences. Malarial anemia is a major global health problem, especially in children, that remains incompletely understood and is not straightforward to treat. Furthermore, the changes in iron metabolism during a malaria infection may modulate susceptibility to coinfections. The release of heme and accumulation of iron in granulocytes may explain increased vulnerability to non-typhoidal Salmonella during malaria. The redistribution of iron away from hepatocytes and into macrophages may confer host resistance to superinfection, whereby blood-stage parasitemia prevents the development of a second liver-stage Plasmodium infection in the same organism. Key to understanding the pathophysiology of iron metabolism in malaria is the activity of the iron regulatory hormone hepcidin. Hepcidin is upregulated during blood-stage parasitemia and likely mediates much of the iron redistribution that accompanies disease. Understanding the regulation and role of hepcidin may offer new opportunities to combat malaria and formulate better approaches to treat anemia in the developing world.

    Bass, Garrett F; Tuscano, Emily T; Tuscano, Joseph M

    2014-01-01

    Uncompensated autoantibody-mediated red blood cell (RBC) consumption is the hallmark of autoimmune hemolytic anemia (AIHA). Classification of AIHA is pathophysiologically based and divides AIHA into warm, mixed or cold-reactive subtypes. This thermal-based classification is based on the optimal autoantibody-RBC reactivity temperatures. AIHA is further subcategorized into idiopathic and secondary with the later being associated with a number of underlying infectious, neoplastic and autoimmune disorders. In most cases AIHA is confirmed by a positive direct antiglobulin test (DAT). The standard therapeutic approaches to treatment of AIHA include corticosteroids, splenectomy, immunosuppressive agents and monoclonal antibodies.

    Full Text Available Thiamine responsive megaloblastic anemia (TRMA is an autosomal recessive disorder, which is caused by loss of function mutations in the SLC19A2 gene. TRMA is characterized by anemia, deafness, and diabetes mellitus. We now report two sisters, the eldest of which presented to a different hospital during childhood with sensorineural deafness, which was treated with a hearing prosthesis, insulin requiring diabetes, megaloblastic anemia. The younger sister is also affected with sensorineural deafness along with diabetes and megaloblastic anemia. Because a diagnosis of TRMA was suspected, therapy with insulin and thiamine was started to which the child is responding. Diabetes associated with deafness and megaloblastic anemia, suggests a diagnosis of TRMA.

    Full Text Available Ravish Shah, Anil K AgarwalDivision of Nephrology, The Ohio State University, Columbus, Ohio, USAAbstract: Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.Keywords: anemia, heart failure, chronic kidney disease, elderly population

    2009-01-01

    In this study, a patient who was hospitalized with a severe anemia in the Internal Medicine Clinic of the Health Research and Application Hospital of Yüzüncü Yil University for one week is presented. The patient had fatigue, paleness and dizziness for one month and approximately 12 kg weight lost for four mounts previous to admission.. Severe iron deficiency anemia was diagnosed in the patient by laboratory analyses. Because there were no hematologic factors associated with severe anemia, the stool examination was also performed. In the Parasitology Laboratory, stool microscopy of the patient revealed numerous ova of hookworm. General condition of the patient well improved with anti-parasitic and anti-anemia treatment. It was concluded that patients with iron deficiency anemia diagnosed in health centers should be also examined for the intestinal parasitic diseases encountered rarely, and physicians should consider non-endemic parasitic diseases in their provinces.

    This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living) and IADL (instrumental activities of daily living). Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    Science.gov (United States)

    Amole, B O; Clarkson, A B; Shear, H L

    1982-01-01

    The pathogenesis of anemia was studied in trypanosome-infected mice. A strain of Trypanosoma brucei, TREU 667, was used which first produces an acute phase marked by waves of parasitemia. Erythrocytes from infected animals were coated with immunoglobulin M during or just before the waves of anemia and parasitological crises. Erythrocytes from normal animals could be sensitized with "precrisis" sera presumably containing antigen and antibody. These data suggest that anemia during the acute phase is due to sensitization of erythrocytes with immunoglobulin M-antigen complexes. The anemia is partially compensated by a strong erythropoietic response. The acute phase is followed by a chronic phase marked by a constant high parasitemia and immunosuppression. The less marked anemia occurring during this latter phase is due to hemodilution and perhaps a low but significant immune response to the parasites, which causes continuing erythrocyte sensitization by immunoglobulin M-antigen complexes.

    2010-02-01

    Iron deficiency is the most common cause of anemia in pregnancy. Pregnant women with anemia are, in general, exclusively treated with iron supplementation. We observed that several pregnant women with anemia who were nonresponsive to iron supplementation also had vitamin B6 deficiency, and that anemia in these cases improved with the administration of vitamin B6. Our prospective study in healthy pregnant women showed that blood levels of iron, ferritin and vitamin B6, in particular, fell to the lower limit of the nonpregnant reference range by the third trimester. We conclude that it is important to take into account the deficiency of vitamin B6 besides iron in the evaluation of anemia during pregnancy.

    Full Text Available Flow cytometric reticulocyte analysis allows the evaluation of reticulocyte maturity. New reticulocyte parameters have been used in the diagnosis and management of anemias, in the bone marrow transplant setting and in the monitoring of iron replacement or erythropoiet in therapy. Reticulocyte numbers and maturation levels have been studied in different hemoglobinopathies and the results have been correlated with the degree of ineffective erythropoiesis. In order to verify differences in reticulocyte parameters in various types of anemias and to test the absolute number of immature reticulocytes as a possible discriminating factor among various types of anemias, reticulocyte counts were performed on 219 samples from patients with sickle cell anemia (SS (n= 62, hemoglobin S trait (n=9, Sbeta thalassemia (n=7, hemoglobin SC disease (n=11, beta thalassemia trait (n=33 and iron deficiency anemia (n= 47, and non-anemic individuals (n= 50. Mean fluorescence index (MFI was defined as representative of the degree of reticulocyte immaturity and it was evaluated as a percentage and in absolute values. Reticulocyte counts and MFI values were significantly higher in SS, Sbeta thalassemic and SC groups when compared to controls, but not different among the three anemia groups. Patients with hemoglobin S trait, iron deficiency anemia and beta thalassemia trait showed reticulocyte parameters similar to the non-anemic group. There was no difference between the b thalassemic trait and iron deficiency anemia in relation to any parameters. MFI in absolute numbers were significantly higher in anemias that develop with the hemolytic process, although this was not evident in MFI percentage values. Our results showed that the erythoid expansion in sickle cell diseases (SS, SC and Sb thalassemia leads to an enhanced immature reticulocyte release from bone marrow and that the phenomena is more evident by the MFI counting in absolute figures than in percentages.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate socio-economic and demographic determinants of anemia among Indian children aged 6-59 months. METHODS: Statistical analysis was performed on the cross-sectional weighted sample of 40,885 children from 2005 to 2006 National Family Health Survey by using multinomial logistic regression to assess the significance of some risk factors in different degrees of child anemia. Anemia was diagnosed by World Health Organization (WHO cut-off points on hemoglobin level. Pearson's chi-squared test was applied to justify the associations of anemia with different categories of the study population. RESULTS: The prevalence of anemia was 69.5%; 26.2% mild, 40.4% moderate, and 2.9% severe anemia. Overall prevalence rate, along with mild and moderate cases, showed an increasing trend up to 2 years of age and then decreased. Rural children had a higher prevalence rate. Of 28 Indian states in the study, 10 states showed very high prevalence, the highest being Bihar (77.9%. Higher birth order, high index of poverty, low level of maternal education, mother's anemia, non-intake of iron supplements during pregnancy, and vegetarian mother increased the risks of all types of anemia among children (p < 0.05. Christian population was at lower risk; and Scheduled Caste, Scheduled Tribe, and Other Backward Class categories were at higher risk of anemia. CONCLUSION: The results suggest a need for proper planning and implementation of preventive measures to combat child anemia. Economically under-privileged groups, maternal nutrition and education, and birth control measures should be priorities in the programs.

    Lu, Shin-Yu; Wu, Hong-Cheng

    2004-12-01

    Thirty patients with a wide range of sore mouth that led to the diagnosis of iron deficiency in 12 patients, pernicious anemia in 8 patients, combined deficiency of iron and vitamin B12 in 2 patients, and anemia of chronic disease in 8 patients were investigated. The oral signs and symptoms included glossitis, glossodynia, angular cheilitis, recurrent oral ulcer, oral candidosis, diffuse erythematous mucositis, and pale oral mucosa. The values of hemoglobin in 30 patients varied from normal to severe life-threatening levels, but none had developed generalized symptoms sufficiently advanced to arouse suspicions of anemia before they visited the Oral Medicine Clinic. The aim of this paper is to describe a retrospective study of 30 patients with oral changes as the initial manifestation of nutritional deficiency or anemia of chronic diseases. Improved diagnosis and classification of anemia based on the mean and heterogeneity of red cell size will be discussed.

  12. Microfluidic approach of Sickled Cell Anemia

    Science.gov (United States)

    Abkarian, Manouk; Loiseau, Etienne; Massiera, Gladys

    2012-11-01

    Sickle Cell Anemia is a disorder of the microcirculation caused by a genetic point mutation that produces an altered hemoglobin protein called HbS. HbS self-assembles reversibly into long rope like fibers inside the red blood cells. The resulting distorded sickled red blood cells are believed to block the smallest capillaries of the tissues producing anemia. Despite the large amount of work that provided a thorough understanding of HbS polymerization in bulk as well as in intact red blood cells at rest, no consequent cellular scale approaches of the study of polymerization and its link to the capillary obstruction have been proposed in microflow, although the problem of obstruction is in essence a circulatory problem. Here, we use microfluidic channels, designed to mimic physiological conditions (flow velocity, oxygen concentration, hematocrit...) of the microcirculation to carry out a biomimetic study at the cellular scale of sickled cell vaso-occlusion. We show that flow geometry, oxygen concentration, white blood cells and free hemoglobin S are essential in the formation of original cell aggregates which could play a role in the vaso-occlusion events.

    1980-07-01

    An autopsy case of erythremia with sideroblastic tumor cell proliferation is described. A 60-year-old man was admitted to the hospital due to general fatigue and anorexia. Bone marrow aspiration revealed abnormalities in erythropoiesis (megaloblasts, 4%; sideroblasts, 84%; ring-formed, 39%, and PAS-positive, 5%). Therapy was directed to pulmonary tuberculosis. Anemia was not improved despite repeated whole blood and platelet transfusions. Serum iron and percentage saturation of the total iron-binding capacity rose during the course. Administration of vitamin B12, B6 or folic acid was inefffective. INAH was replaced by its derivative, IHMS, during the course, but the population of sideroblasts especially of ring-sideroblasts was invariably large (78%-100% and 39%-65% for total sideroblasts and ring-sideroblasts, respectively). He died with increasing abdominal pain and jaundice after three months' hospitalization. Main autopsy findings were: diffuse proliferation of atypical erythroblasts in the bone marrow, systemic lymph nodes, liver, spleen and kidneys. Most of the cells positively stained with iron. Tuberculosis of lungs with cavity formation. Discussion is focussed on the relationship between erythremia and sideroblastic anemia.

    Full Text Available Introduction. Cameron lesions are linear gastric ulcers or erosions positioned on the crests of mucosal folds at the diaphragmatic impression, in patients with large hiatal hernia, and can cause iron deficiency anaemia. Case report. We present a case of a 56-year-old woman who was referred to our institution for further investigation after she was examined in gastroenterology emergency room (GER for signs and symptoms of severe hypochromic microcytic anemia without signs of acute gastrointestinal bleeding and with no obvious cause of chronic blood loss. Endoscopy showed linear ulceration at the level of diaphragm-Cameron lesions with large hiated hernia. She was treated with proton pump inhibitors and iron supplements. The laparoscopic fundoplication was done. Six months later she was asymptomatic. Conclusion. Large hiatus hernia may cause iron deficiency anemia due to occult bleeding from Cameron erosions. The current therapy concept includes the surgical reconstruction of the hiatus together with gastric fundoplication in combination with the proton pump inhibitor therapy.

    This study was conducted to determine the optimum dose of supplemental iron for prophylaxis against pregnancy anemia. One hundred and ten pregnant women were randomly allocated to three groups: Group A receiving equivalent of 60 mg, group B 120 mg and Group C 240 mg, elemental iron as ferrous sulphate daily; the content of folic acid was constant in all the three groups (0.5 mg). These women had at least consumed 90 tablets in 100 +/- 10 days. Blood was drawn at the beginning and at the end of the treatment. Fifty percent were anemic (less than 11 g/100 ml). The hemoglobin levels rose similarly in all groups and the differences were statistically not significant. Fifty-six percent had depleted iron stores (serum ferritin value less than 12 micrograms/l) at the beginning of the study. Following therapy a statistically significant increase in iron stores was observed in group B and C as compared to group A. The difference between group B and C was not significant. The side effects increased with increasing doses of iron; 32.4%, 40.3% and 72% in group A, B and C respectively. Based on these findings, the authors advocate that optimum dose of iron should be 120 mg instead of 60 mg as is currently being used in the National Nutritional Anemia Prophylaxis Programme.

    2013-01-01

    Full Text Available Warm autoimmune hemolytic anemia (WAIHA is one of four clinical types of autoimmune hemolytic anemia (AIHA, with the characteristics of autoantibodies maximally active at body temperature. It produces a variable anemia—sometimes mild and sometimes severe. With respect to the absence or presence of an underlying condition, WAIHA is either idiopathic (primary or secondary, which determines the treatment strategies in practice. Conventional treatments include immune suppression with corticosteroids and, in some cases, splenectomy. In recent years, the number of clinical studies with monoclonal antibodies and immunosuppressants in the treatment of WAIHA increased as the knowledge of autoimmunity mechanisms extended. This thread of developing new tools of treating WAIHA is well exemplified with the success in using anti-CD20 monoclonal antibody, Rituximab. Following this success, other treatment methods based on the immune mechanisms of WAIHA have emerged. We reviewed these newly developed immunotherapy treatments here in order to provide the clinicians with more options in selecting the best therapy for patients with WAIHA, hoping to stimulate researchers to find more novel immunotherapy strategies.

Classification of AIHA is based on the optimal auto-RBC antibody reactivity temperatures and includes warm, cold-reactive, mixed AIHA, and drug-induced AIHA subtypes. AIHA is a rare disease, and recommendations for transfusion are based mainly on results from retrospective data and relatively small cohort studies, including heterogeneous patient samples or single case reports. In this article, we will review the challenges and solutions to safely transfuse AIHA patients. We will reflect on the indication for transfusion in AIHA and the difficulty in the accomplishment of immunohematological procedures for the selection of the safest and most compatible RBC units.

    Full Text Available Anemia de Doença Crônica (ADC é usualmente definida como a anemia que ocorre em distúrbios infecciosos crônicos, inflamatórios ou doenças neoplásicas, e é uma das síndromes clínicas mais comuns na prática clínica. Caracteristicamente, ADC corresponde à anemia normocrômica/normocítica, leve a moderada, e caracteriza-se por hipoferremia na presença de estoques adequados de ferro. Os três principais mecanismos patológicos envolvidos na ADC são: diminuição da sobrevida da hemácia, falha da medula óssea em aumentar a produção de glóbulos vermelhos para compensar o aumento da sua demanda, e distúrbio da mobilização do ferro de depósito do sistema mononuclear fagocitário. O papel central dos monócitos e dos macrófagos e o aumento da produção de citocinas mediadoras da resposta imune ou inflamatória, tais como: TNF alfa, INF gama e IL-1 estão implicados nos três processos envolvidos no desenvolvimento da ADC. O propósito desse artigo é revisar os recentes avanços no entendimento dos aspectos patofisiológico, diagnóstico e terapêutico desta síndrome.The anemia of chronic disease (ACD is usually defined as the anemia occurring in chronic infectious, inflammatory disorders, or neoplastic diseases, and is one of the most common syndromes in the clinical practice. Characteristically, ACD is a mild-to-moderate, normochromic/normocytic anemia, and is characterized by hypoferremia in the presence of adequate iron stores. The three principal pathologic mechanisms involved in ACD are: reduced erythrocyte survival, bone marrow failure to increase red blood cell production to compensate for the increase in its demand, and abnormal mobilization of reticuloendothelial iron stores. The central role of monocytes and macrophages, and the increased production of the cytokines that mediate the immune or inflammatory response, such as tumor necrosis factor, interleukin-1 and the interferons, are implicated in all three

    Full Text Available El hematocrito (Hto, como indicador de anemia en individuos y poblaciones, experimenta variaciones en función de factores mesológicos y genéticos. La anemia constituye una enfermedad endémica cuya prevalencia en Argentina, en distintos grupos de edad y de riesgo y particularmente en escolares, es insuficientemente conocida. El objetivo de este trabajo fue conocer la variación del Hto en escolares de la ciudad de San Salvador de Jujuy localizada a 1200 m.s.n.m., evaluar la prevalencia de anemia y relacionar estas variaciones con las características socioeconómicas de la población. Los datos del Hto procedieron de 17.580 escolares de escuelas públicas y privadas. Para su análisis se agruparon por edad, sexo y nivel socio-económico. Se consideró como anémicos a los niños cuyo Hto se encontró por debajo de: a el valor mínimo aceptado para el nivel de 1200 m; b -2 desviaciones estándar. Para el análisis se empleó: ANOVA, c2 y coeficiente de correlación. Los valores promedio del Hto, independientemente de la edad, sexo y nivel socioeconómico, coinciden con los de la referencia ajustados para la altura. Se observaron: a diferencias intersexuales estadísticamente significativas, presentando los varones, valores superiores a los de las mujeres; b una tendencia al aumento del Hto con relación al incremento del nivel socioeconómico. La prevalencia de anemia, independientemente del criterio utilizado, fue baja en ambos sexos, grupos de edad y en todos los niveles socioeconómicos. Los valores del hematocrito: a son representativos de una población escolar situada a una altitud moderada; b pese a la tendencia a disminuir en el nivel socioeconómico bajo no superan, en la mayoría de los casos, el nivel crítico de anemia; c no indican presencia de desnutrición en la población escolar examinada.The hematocrit (Ht, as an indicator of anemia in individuals and populations, shows variations in relation to mesologic and genetic factors

    objectives To demonstrate the phenomena and explore the causes of anemia in patients with chronic heart failure (CHF). Methods To observe the phenomena of anemia in patients with CHF, a total of 276 patients with CHF were included in this retrospective study. The clinical characteristics of the patients are: mean age 69.2±11.0 years; male 151,female 125; NYHA Ⅲ and Ⅳ 115 (41.7%). Results ①Among the 276 patients with CHF, 81 (29.4%)had anemia (Mean hemoglobulin concentration 101.5±13.0g/L). ② Patients with Anemia were more likely to be female and to have greater NYHA (Ⅲ or Ⅳ) (P<0.05), higher serum creatinine, as well as lower serum albumin and low-density lipoprotein levels (P<0.01).③ A weak negative correlation was also noted between the level of NYHA and hemoglobulin. ④ There was no significant difference in age, the primary cardiac etiology of the CHF, the history of diabetes, left ventricular end diastolic diameter, and left ventricular ejection fraction between CHF patient with and without anemia. Conclusions The prevalence of anemia is high among patients with CHF. The anemia patients with CHF tend to be female, have greater cardiac and renal functional impairment, but with lower serum albumin and LDL that suggests some degree of malnutrition.

    Anemia is a frequent complication in patients with inflammatory bowel disease (IBD), and is associated with decreased quality of life and increased rate of hospitalization. The primary therapeutic targets of IBDassociated anemia are iron deficiency and anemia of chronic disease. An important prognostic parameter of the success or failure of therapy is the outcome of the underlying disease. Iron deficiency should be appropriately managed with iron supplementation.However, the use of oral iron therapy is limited by several problems, the most important being gastrointestinal side effects leading occasionally to disease relapse and poor iron absorption. Intravenous iron preparations are more reliable, with iron sucrose demonstrating the best efficacy and tolerability. Treatment with erythropoietin or darbepoetin has been proven to be effective in patients with anemia, who fail to respond to intravenous iron. Patients with ongoing inflammation have anemia of chronic disease and may require combination therapy comprising of intravenous iron sucrose and erythropoietin. After initiating treatment, careful monitoring of hemoglobin levels and iron parameters is needed in order to avoid recurrence of anemia. In conclusion, anemia in the setting of IBD should be aggressively diagnosed, investigated, and treated. Future studies should define the optimal dose and schedule of intravenous iron supplementation and appropriate erythropoietin therapy in these patients.

    The objective of this study was to assess the prevalence of anemia and iron deficiency (ID) of a nationally representative sample of the Kuwait population. We also determined if anemia differed by socioeconomic status or by RBC folate and vitamins A and B12 levels. The subjects who were made up of 1830 males and females between the ages of 2 months to 86 years, were divided into the following age groups (0-5, 5-11, 12-14, 15-19, 20-49, ≥50 years). Results showed that the prevalence of anemia was 3% in adult males and 17% in females. The prevalence of ID varied according to age between 4% (≥50 years) and 21% (5-11 years) and 9% (12-14 years) and 23% (15-19 years), respectively, in males and females. The prevalence of anemia and ID was higher in females compared to males. Adults with normal ferritin level, but with low RBC folate and vitamins A and B12 levels had higher prevalence of anemia than those with normal RBC folate and vitamins A and B12 levels. This first nationally representative nutrition and health survey in Kuwait indicated that anemia and ID are prevalent and ID contributes significantly to anemia prevalence.

    Inorganic phosphate (Pi) plays critical roles in bone metabolism and is an essential component of 2,3-diphosphoglycerate (2,3-DPG). It has been reported that animals fed a low-iron diet modulate Pi metabolism, whereas the effect of dietary Pi on iron metabolism, particularly in iron deficiency anemia (IDA), is not fully understood. In this study, we hypothesized the presence of a link between Pi and iron metabolism and tested the hypothesis by investigating the effects of dietary Pi on iron status and IDA. Wistar rats aged 4 weeks were randomly assigned to 1 of 4 experimental dietary groups: normal iron content (Con Fe)+0.5% Pi, low-iron (Low Fe)+0.5% Pi, Con Fe+1.5% Pi, and Low Fe+1.5% Pi. Rats fed the 1.5% Pi diet for 14 days, but not for 28 days, maintained their anemia state and plasma erythropoietin concentrations within the reference range, even under conditions of low iron. In addition, plasma concentrations of 2,3-DPG were significantly increased by the 1.5% Pi diets and were positively correlated with plasma Pi concentration (r=0.779; Piron-regulated genes, including divalent metal transporter 1, duodenal cytochrome B, and hepcidin. Furthermore, iron concentration in liver tissues was increased by the 1.5% Pi in Con Fe diet. These results suggest that dietary Pi supplementation delays the onset of IDA and increases plasma 2,3-DPG concentration, followed by modulation of the expression of iron-regulated genes.

    Myelodysplastic syndromes (MDS) are a constellation of different diseases sharing anemia in the great majority of cases, and this cytopenia defines these pathologies and their most dramatic clinical manifestations. Anemia in MDS is due to ineffective erythropoiesis, with a high degree of apoptosis of marrow erythroid progenitors. These progenitors show distinctive dysplastic features that consent diagnosis, and are recognizable and differentiated, although not easily, from other morphologic alterations present in other types of anemia. Reaching the diagnosis of MDS in a macrocytic anemia and alleviating the symptoms of anemia are therefore an essential objective of the treating physician. In this work, the signs and symptoms of anemia in MDS, as well as its peculiar pathophysiology, are discussed. Erythopoietic stimulating agents (ESAs) are providing the best treatment for anemic MDS patients, but their use is still not approved by health agencies. While still waiting for this waiver, their clinical use is widespread and their effectivness is well known, as well as the dismal prognosis of patients who do not respond to ESAs and require transfusions. MDS with del5q constitute a unique model of anemia whose complex pathophysiology has been clarified at least partially, defining its link to ribosomal alterations likewise what observed in hereditary anemias like Blackfan Diamond anemia. Lenalidomide is the agent that has shown striking and specific erythropoietic activity in del5q MDS, and the basis of this response is starting to be understood. Several new agents are under evaluation for ESA refractory/relapsed MDS patients, targeting different putative mechanisms of ineffective erythropoiesis, and are here reviewed.

    Full Text Available Sideroblastic anemia, comprising of acquired and congenital forms, is a heterogeneous group of disorders characterized by the presence of ring sideroblasts in the bone marrow. Congenital sideroblastic anemia is a rare condition which is mostly X-linked, caused by mutations of delta-aminolevulinic acid synthase 2. We describe two cases of congenital sideroblastic anemia, one of them indicating an autosomal recessive inheritance, with their clinico-hematological profile. It is important to recognize this entity early in life as a significant percentage of cases respond to pyridoxine thus avoiding any long-term complications.

    Anemia of chronic disease is normocytic and normochromic. One of the mechanisms is misbalance of iron metabolism. Hepcidin, a kind of protein secreted by liver is considered to be the hormone regulating iron metabolism. It binds to ferroportin and induces the latter one's internalization. Thus, iron transportation from iron storage cells to serum is reduced. Cytokines are elevated in chronic disease. They stimulate hepcidin expression in liver through JAK2/STAT3 pathway. As a result, iron absorption and reabsorption is blocked, which leads to the misbalance of iron metabolism in anemia of chronic disease. In this article, the hepcidin and its relation to iron metabolism and anemia in chronic disease are reviewed.

    2006-11-01

    Recent developments in sickle cell research and blood flow modeling allow for new interpretations of the sickle cell crises. With an appropriate set of theoretical and empirical equations describing the dynamics of the red cells in their environment, and the response of the capillaries to major changes in the rheology, a complete mathematical system has been derived. This system of equations is believed to be of major importance to provide new and significant insight into the causes of the disease and related crises. With simulations, it has been proven that the system transition from a periodic solution to a chaotic one, which illustrates the onset of crises from a regular blood flow synchronized with the heart beat. Moreover, the analysis of the effects of various physiological parameters exposes the potential to control chaotic solutions, which, in turn, could lead to the creation of new and more effective treatments for sickle cell anemia. .

    1992-10-01

    The genetics of sickle cell anemia may be considered as a model. Its mendelian transmission was hypothesized even before the molecular era. Once the mutation identified, it could be studied at the protein and DNA level; a consistent pathophysiological mechanism was proposed; the various genetic forms of the disease could be identified; the way by which a balanced polymorphism with Plasmodium falciparum malaria is obtained was analyzed. More recently, investigations were run in order to understand how modulating, or epistatic factors could modify the pathophysiological mechanism and contribute to the high clinical diversity of the disease. Several factors have been identified, among which a concomitant alpha-thalassemia, an overproduction of fetal hemoglobin, due either to an activation of the gamma genes or to an increase of the F-cell number, and finally a quantitative control of the beta s chains themselves. Such a high number of genetic active factors questions the concept itself of a monogenic disease.

    The congenital dyserythropoietic anemias (CDAs) are a heterogeneous group of genetic disorders of red cell production. They are characterized by ineffective erythropoiesis and dyserythropoiesis. Here, we present the clinical description and mutation analysis of a Japanese female with CDA type 1. She has long been diagnosed with unclassified congenital hemolytic anemia from the neonatal period. However, bone marrow morphology and genetic testing of the CDAN1 gene at the age of 12 years confirmed the afore-mentioned diagnosis. Thus, we should be aware of the possibility of CDA if the etiology of congenital anemia or jaundice cannot be clearly elucidated.

    Full Text Available A hipertensão pulmonar é uma complicação comum em pacientes com anemia falciforme. A despeito das elevações leves das pressões pulmonares desses pacientes, a morbimortalidade é alta e, em pacientes adultos com anemia falciforme, a hipertensão pulmonar é um fator de risco muito importante. A patogênese da hipertensão pulmonar relacionada à anemia falciforme é multifatorial e inclui hemólise, baixos níveis de óxido nítrico, hipóxia crônica, tromboembolismo, doença hepática crônica e asplenia. Na maioria dos pacientes, a hipertensão arterial pulmonar é a causa principal para as elevações na pressão arterial pulmonar, mas a hipertensão pulmonar venosa também é um fator contribuinte em alguns pacientes. Existem poucos estudos específicos avaliando os efeitos de tratamento para a hipertensão pulmonar em pacientes com anemia falciforme. É provável que a intensificação da terapia para a anemia hemolítica em todos os pacientes e o tratamento específico para a hipertensão pulmonar em pacientes com doença severa sejam benéficos. Estudos de grande porte avaliando o efeito do tratamento da hipertensão pulmonar em pacientes com anemia falciforme estão em andamento.Pulmonary hypertension is a common complication of sickle cell anemia. Despite the fact that the elevations in pulmonary artery pressures are slight, morbidity and mortality are high. In adult sickle cell anemia patients, pulmonary hypertension is emerging as a major risk factor for death. The pathogenesis of sickle cell anemia-related pulmonary hypertension is multifactorial, including hemolysis, impaired nitric oxide bioavailability, chronic hypoxemia, thromboembolism, chronic liver disease and asplenia. In the majority of patients, pulmonary arterial hypertension is the main cause of elevated pulmonary artery pressures. However, pulmonary venous hypertension also plays a role in a subgroup of patients. Specific data on the effects of treatment

    2013-01-01

    Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available.

    Full Text Available AIMS AND OBJECTIVE: To investigate possible association between Anemia and Gestational Diabetes Mellitus (GDM. DESIGN, SETTING & PARTICIPANTS: A cross sectional study comprising of 100 GDM patients attending as outpatients or In-patients at Vani Vilas hospital and Bowring & Lady Curzon hospital, BMC & RI, Bangalore. MAIN MEASUREMENTS: GDM patients either newly diagnosed or on follow up were selected and complete blood counts including the peripheral smear, blood sugar levels and HbA1c were done. RESULTS: Anemia was diagnosed in 6 patients (6% who are considerably less compared to Non-GDM pregnancy (40-50%. Out of which only 1 patient’s peripheral smear showed Microcytic hypochromic blood picture whereas rest showed Normocytic Normochromic picture. CONCLUSION: Our study suggests that incidence of Anemia especially Microcytic Hypochromic Anemia is considerably lower in GDM. These finding suggests that routine supplementation of Iron irrespective of Hemoglobin (Hb levels should be reconsidered in risk group women.

    Sex chromosome aneuploidies range in incidence from rather common to exceedingly rare and have a variable phenotype. We report 2 patients with sex chromosome aneuploidies who developed severe aplastic anemia requiring treatment. The first patient had tetrasomy X (48,XXXX) and presented at 9 years of age, and the second patient had trisomy X (47,XXX) and presented at 5 years of age. Although aplastic anemia has been associated with other chromosomal abnormalities, sex chromosome abnormalities have not been traditionally considered a risk factor for this condition. A review of the literature reveals that at least one other patient with a sex chromosome aneuploidy (45,X) has suffered from aplastic anemia and that other autosomal chromosomal anomalies have been described. Despite the uncommon nature of each condition, it is possible that the apparent association is coincidental. A better understanding of the genetic causes of aplastic anemia remains important.

    Full Text Available Hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (AVR.The mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. It appears to be independent of its severity as assessed by echocardiography. We present a case of a 24-year-old man with a history of AVR in 10 year ago that developed severe hemolytic anemia due to a mild subvalvar stenosis caused by pannus formation and mild hypertrophic septum. After exclusion of other causes of hemolytic anemia and the lack of clinical and laboratory improvement, the patient underwent redo valve surgery with pannus and subvalvar hypertrophic septum resection. Anemia and heart failure symptoms gradually resolved after surgery

    The gastrointestinal (GI) tract is a common site of bleeding that may lead to iron deficiency anemia (IDA). Treatment of IDA depends on severity and acuity of patients’ signs and symptoms. While red blood cell transfusions may be required in hemodynamically unstable patients, transfusions should be avoided in chronically anemic patients due to their potential side effects and cost. Iron studies need to be performed after episodes of GI bleeding and stores need to be replenished before anemia develops. Oral ...

    Full Text Available Anemia is a very common disorder both in clinical practice and in the community. The recent rise in the population of the elderly has become the focus of attention in developing countries, because of the increasing longevity of the elderly, whilst the prevalence of anemia increases with age. The objective of this study was to determine the prevalence of anemia and its association with the quality of life in the elderly. A cross-sectional study was conducted from April to June 2008, located in the Mampang Prapatan district, South Jakarta. A total of 298 elderly persons participated in this study, comprising 109 (36.6% males and 189 (63.4% females. Anemia was measured by the parameters of hemoglobin and quality of life was assessed by the WHOQOL-BREF instrument, a short version of the WHOQOL-100 instrument. The results of the study showed the prevalence of anemia to be 26.2%, with a higher prevalence rate in females compared with males. The quality of life in the physical, psychological, social and environmental domains differed significantly with decreasing hemoglobin levels, whereas the physical and mental quality of life declined significantly with age. Anemia is thus indicative of a reduction in the quality of life of the elderly.

    Full Text Available The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases, with particular reference to anemias and disorders of hemostasis. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases, with emphasis on anemia. Mesh phrases used in the search were: oral diseases AND anaemia; orofacial diseases AND anaemia; orofacial lesions AND anaemia; orofacial manifestations AND disorders of haemostasis. The Boolean operator "AND" was used to combine and narrow the searches. Anemic disorders associated with orofacial signs and symptoms include iron deficiency anemia, Plummer-Vinson syndrome, megaloblastic anemia, sickle cell anemia, thalassaemia and aplastic anemia. The manifestations include conjunctiva and facial pallor, atrophic glossitis, angular stomatitis, dysphagia, magenta tongue, midfacial overgrowth, osteoclerosis, osteomyelitis and paraesthesia/anesthesia of the mental nerve. Orofacial petechiae, conjunctivae hemorrhage, nose-bleeding, spontaneous and post-traumatic gingival hemorrhage and prolonged post-extraction bleeding are common orofacial manifestations of inherited hemostatic disorders such as von Willebrand′s disease and hemophilia. A wide array of anemic and hemostatic disorders encountered in internal medicine has manifestations in the oral cavity and the facial region. Most of these manifestations are non-specific, but should alert the hematologist and the dental surgeon to the possibilities of a concurrent disease of hemopoiesis or hemostasis or a latent one that may subsequently manifest itself.

    Patients surviving sepsis develop anemia but the molecular mechanism is unknown. Here we observed that mice surviving polymicrobial Gram-negative sepsis develop hypochromic, microcytic anemia with reticulocytosis. The bone marrow of sepsis survivors accumulates polychromatophilic and orthochromatic erythroblasts. Compensatory extramedullary erythropoiesis in the spleen is defective during terminal differentiation. Circulating TNF and IL-6 are elevated for five days after the onset of sepsis, and serum HMGB1 levels are increased from day seven until at least day 28. Administration of recombinant HMGB1 to healthy mice mediates anemia with extramedullary erythropoiesis and significantly elevated reticulocyte counts. Moreover, administration of anti-HMGB1 monoclonal antibodies after sepsis significantly ameliorates the development of anemia (hematocrit 48.5±9.0% versus 37.4±6.1%, p<0.01, hemoglobin 14.0±1.7g/dL versus 11.7±1.2g/dL, p<0.01). Together, these results indicate that HMGB1 mediates anemia by interfering with erythropoiesis, suggesting a potential therapeutic strategy for anemia in sepsis.

    Full Text Available In some renal allograft recipients, anemia persists or develops following transplantation. Anemia is associated with pre-operative blood loss and allograft dysfunction, including delayed graft function, acute rejection and chronic allograft dysfunction. To study the prevalence and association of post-renal transplant anemia, we studied 200 renal transplant recipients; 131 (65.5% patients were males and 69 (34.5% patients were females, and age ranged from 17 to 67 years, with a mean of 37.7 ± 10.8 years. All patients were receiving cyclosporine, prednisolone and mycophenolate mofetil (MMF. Complete blood count was done at two times: three and six months post-renal transplant. There were 74% anemic patients three months after renal transplantation and 45% anemic patients six months after renal transplantation. High creatinine value, female gender, delayed graft function, episodes of acute rejection, perioperative blood loss and infections were the only significant independent risk factors for prevalence of anemia post-renal transplant. In our study, we did not find an association between MMF and cyclosporine nor angiotensin-converting enzyme inhibitors (ACEIs or angiotensin receptors blocker (ARBs with anemia. This study demonstrates that anemia is a common complication during the first six months after kidney transplantation, with several risk factors precipitating this complication.

    Full Text Available Introduction: refractory iron-deficiency anemia has a multifactorial origin related to various gastrointestinal conditions, with celiac disease plus malabsorption and IBD together with isolated gluten intolerance being most common. Objectives: to determine the prevalence of serum, genetic, and histological markers for gluten intolerance, and to analyze the response to gluten withdrawal from the diet in these patients. Methods: a number of patients with refractory anemia were prospectively and consecutively enrolled. A protocol to measure serum (TGt-2, genetic (HLA-DQ2/DQ8, and histological markers for celiac disease was applied. All followed a gluten-free diet for a median 3.6 years. Sustained remission of anemia during follow-up was interpreted as positive response. Results: ninety-eight patients (84% females with a mean age of 54 years were studied. Anti-TGt2 antibodies were positive in 5% of cases. A total of 67 cases (68% were haplotype HLA-DQ2 or -DQ8 (+. We found villous atrophy (Marsh III in 13% of patients, and an inflammatory pattern (Marsh I or II in 13%. All remaining 72 patients (74% had no histological duodenal changes. Age, anemia duration, number of transfusions, number of parenteral iron doses, and time on a gluten-free diet were all compared according to the presence or absence of villous atrophy and HLA-DQ2/8 positivity, and no significant differences were found for any of the analyzed variables. Response was positive in 92% of subjects. Conclusions: celiac disease with villous atrophy is rarely a cause of refractory anemia. Gluten intolerance with no histological lesions is seen in almost 75% of patients, and therefore plays a relevant role in its development.Introducción: la anemia ferropénica refractaria presenta un origen multifactorial, relacionado con diversas enfermedades digestivas, siendo las más frecuentes la enfermedad celiaca con malabsorción y la EII junto con la intolerancia al gluten aislada.

    Anemia is common among young women, and iron deficiency is one of the leading causes. In Europe and the US, the iron fortification of flour increased oral iron intake and decreased anemia prevalence from 30% to 10%. The National Nutrition Survey in Japan revealed that anemia prevalence among young Japanese women is increasing; however, no nationwide preventive policy has been aimed at iron deficiency anemia. The endpoint of this study was the estimation of anemia prevalence among healthy Japanese woman, based on a large sample size. We collected data from the consecutive check-up examination records of apparently healthy women (n = 13,147). We defined hemoglobin lower than 12 g/dL as anemia, hemoglobin lower than 10 g/dL as severe anemia, and a mean corpuscular volume lower than 80 fl as microcytic anemia. Of the 13,147 persons, anemia was identified in 2331 (17.3 %), and severe and microcytic anemia in 438 (3.3 %) and 700 (5.2 %), respectively. Among women younger than 50 years, anemia was identified in 22.3 %, and 25.2 % of them had severe anemia. In conclusion, the prevalence of anemia and severe anemia among young women is high in Japan. Some action needs to be considered to improve women's quality of life.

    Full Text Available A anemia aplástica é distúrbio caracterizado por pancitopenia e medula óssea hipocelular, com substituição gordurosa dos elementos e sem nenhum sinal de transformação maligna ou doença mieloproliferativa. Acomete geralmente adultos jovens e idosos, sem preferência sexual. A maioria dos casos é adquirida, mas pode ocorrer hereditariamente, por distúrbio molecular (anemia de Fanconi. A associação com gravidez é rara, estando relacionada com alta morbidade e mortalidade materna e fetal. Os autores descrevem o caso de uma paciente com anemia aplástica, diagnosticada previamente, cuja gestação complicou com infecção do trato urinário, doença hipertensiva específica da gestação e restrição de crescimento fetal, com parto prematuro eletivo. Apesar das condições adversas na gravidez e parto, mãe e recém-nascido tiveram evolução clínica satisfatória.Aplastic anemia is characterized by a circulating pancytopenia, hypocellularity, and fatty replacement of cellular marrow elements, without evidence of malignant transformation or myeloproliferative disease. It usually affects young and senior adults, without any sexual preference. Most cases of aplastic anemia are acquired, but the disease may also be inherited due to a molecular disorder (Fanconi's anemia. Aplastic anemia in pregnancy is an extremely rare condition with high maternal and fetal morbidity and mortality rates. The authors describe a case of a patient with previously diagnosed aplastic anemia, whose pregnancy was complicated with urinary tract infection, preeclampsia and fetal growth restriction, with elective preterm birth. In spite of the adverse conditions in pregnancy and delivery, mother and newborn had a satisfactory clinical evolution.

    Full Text Available Iron deficiency anemia (IDA and anemia of chronic disease are the most commonly confused anemias. We investigate the diagnostic value of erythrocyte indices, red cell volume distribution width, and serum ferritin levels to make differential diagnosis of anemia in controls and anemic patients.Iron deficiency anemia (44 patients, anemia of chronic disease (41, IDA with anemia of chronic disease (17 and control (50 groups were compared. We performed serum ferritin, CBC, and sedimentation rate in all patientsand bone marrow aspiration in patients with anemia of chronic disease.Although mean cell volume (MCV and mean corpuscular hemoglobin (MCH are low in IDA and anemia of chronic disease, it is much striking in the former one (p<0.001, p<0.001. Only 7.3% of patients with anemia of chronic disease had a MCV<70 fL and MCH<24 pg, 90.0% of patients with IDA were below that cut-off point. Serum ferritin means were in patients with IDA and anemia of chronic disease were 4.6±3.3 and 489.6 ±519.9 ng/ml, respectively.The probability of IDA is low when RDW is normal in microcytic anemias. RDW is high in half of patients with anemia of chronic disease. Reference values for ferritin must be changed in patients with anemia of chronic disease and IDA. If serum ferritin is 57.6-146.4 ng/ml anemia of chronic disease and iron deficiency must ruled out by other diagnostic tests.

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

    Full Text Available Advances in iron metabolism have allowed a novel classification of iron disorders and to identify previously unknown diseases. These disorders include genetic iron overload (hemochromatosis and inherited iron-related anemias, in some cases accompanied by iron overload. Rare inherited anemias may affect the hepcidin pathway, iron absorption, transport, utilization and recycling. Among the genetic iron-related anemias the most common form is likely the iron-refractory iron-deficiency anemia (IRIDA, due to mutations of the hepcidin inhibitor TMPRSS6 encoding the serine protease matriptase-2. IRIDA is characterized by hepcidin up-regulation, decrease iron absorption and macrophage recycling and by microcytic- hypochromic anemia, unresponsive to oral iron. High serum hepcidin levels may suggest the diagnosis, which requires demonstrating the causal TMPRSS6 mutations by gene sequencing. Other rare microcytic hypochromic anemias associated with defects of iron transport-uptake are the rare hypotransferrinemia, and DMT1 and STEAP3 mutations. The degree of anemia is variable and accompanied by secondary iron overload even in the absence of blood transfusions. This is due to the iron-deficient or expanded erythropoiesis that inhibits hepcidin transcription, increases iron absorption, through the erythroid regulator, as in untransfused beta-thalassemia. Sideroblastic anemias are due to decreased mitochondrial iron utilization for heme or sulfur cluster synthesis. Their diagnosis requires demonstrating ringed sideroblasts by Perl’s staining of the bone marrow smears. The commonest X-linked form is due to deltaamino- levulinic-synthase-2-acid (ALAS2 mutations. The recessive, more severe form, affects SLC25A38, which encodes a potential mitochondrial importer of glycine, an amino acid essential for ALA synthesis and thus results in heme deficiency. Two disorders affect iron/sulfur cluster biogenesis: deficiency of the ATP-binding cassette B7 (ABCB7 causes X

    Full Text Available Hoy día, tres tendencias influyen directamente en la conformación de la escuela. En primer lugar, el afán de encontrar la esencia de todo encumbró a la razón e hizo de la racionalidad el único valor a defender en las aulas. En segundo lugar, el sistema capitalista hizo lo mismo con aquello que tiene valor de uso y valor de cambio, es decir, con la mercancía, validando solo lo que puede tener una utilidad económica conocida o posible. Esto convirtió a la educación en un proceso para certificar y ganar dinero, desdibujando así su intención de formar personas. Finalmente, la visión masculina y eurocéntrica con su locura por quererlo dominar todo, y de pensar que el hombre era el dueño del planeta e inclusive la vida y el destino de los otros hombres, mutiló culturas y eliminó a la naturaleza de los currículums en los centros educativos.

    Full Text Available INTRODUCTION: Sickle cell anemia and thalassemia result in impaired bone health in both adults and youths. Children with other types of chronic hemolytic anemia may also display impaired bone health. STUDY DESIGN: To assess bone health in pediatric patients with chronic hemolytic anemia, a cross-sectional study was conducted involving 45 patients with different forms of hemolytic anemia (i.e., 17 homozygous sickle cell disease and 14 hereditary spherocytosis patients. Biochemical, radiographic and anamnestic parameters of bone health were assessed. RESULTS: Vitamin D deficiency with 25 OH-vitamin D serum levels below 20 ng/ml was a common finding (80.5% in this cohort. Bone pain was present in 31% of patients. Analysis of RANKL, osteoprotegerin (OPG and osteocalcin levels indicated an alteration in bone modeling with significantly elevated RANKL/OPG ratios (control: 0.08+0.07; patients: 0.26+0.2, P = 0.0007. Osteocalcin levels were found to be lower in patients compared with healthy controls (68.5+39.0 ng/ml vs. 118.0+36.6 ng/ml, P = 0.0001. Multiple stepwise regression analysis revealed a significant (P<0.025 influence of LDH (partial r2 = 0.29, diagnosis of hemolytic anemia (partial r2 = 0.05 and age (partial r2 = 0.03 on osteocalcin levels. Patients with homozygous sickle cell anemia were more frequently and more severely affected by impaired bone health than patients with hereditary spherocytosis. CONCLUSION: Bone health is impaired in pediatric patients with hemolytic anemia. In addition to endocrine alterations, an imbalance in the RANKL/OPG system and low levels of osteocalcin may contribute to this impairment.

    Full Text Available INTRODUCTION: Sideropenic anemia is one of the most common nutritional disorders in the world. The children are at higher risk of iron deficiency than adults due to their rapid growth during infancy and relatively higher requirements of iron. OBJECTIVE: The objective of our study was to investigate the prevalence of sideropenic anemia in pre-school children and relevant risk factors. METHOD: Study on sideropenic anemia of preschool children was performed in Zaječar Municipality in 2003. Subjects: all children, age 6-7 years, who lived in the Zaječar Municipality (554 children. The investigation included: interview of children's parents and laboratory analysis of blood. RESULTS: The frequency of sideropenic anemia was 5.23% in tested children (hemoglobin level less than 11g/dl. Sex and place of residence had no significant impact on hemoglobin concentration in blood of children. Likewise, social status and education of parents had no significant impact on iron deficiency anemia. Higher incidence of infections was found in children with lower hemoglobin concentration in blood (p<0.05. It made no difference if children attended the kindergarten or not. Nutrition of children in kindergarten does not correct domestic nutrition, which should be one of its basic roles. CONCLUSION: Since sideropenic anemia gives rise to serious health problems, such as poor cognitive and motor development and behavioral problems, it is important to take corrective measures regarding domestic and social nutrition of children. Therefore, it is necessary to take action in preventing the sideropenic anemia and provide normal growth and development.

    Each of the thirteen identified Fanconi anemia (FA) genes is required for resistance to DNA interstrand crosslinking agents, such as mitomycin C, cisplatin, and melphalan. While these agents are excellent tools for understanding the function of FA proteins in DNA repair, it is uncertain whether a defect in the removal of DNA interstrand crosslinks (ICLs) is the basis for the pathophysiology of FA. For example, DNA interstrand crosslinking agents induce other types of DNA damage, in addition to ICLs. Further, other DNA-damaging agents, such as ionizing or ultraviolet radiation, activate the FA pathway, leading to monoubiquitination of FANCD2 and FANCI. Also, FA patients display congenital abnormalities, hematologic deficiencies, and a predisposition to cancer in the absence of an environmental source of ICLs that is external to cells. Here we consider potential sources of endogenous DNA damage, or endogenous stresses, to which FA proteins may respond. These include ICLs formed by products of lipid peroxidation, and other forms of oxidative DNA damage. FA proteins may also potentially respond to telomere shortening or replication stress. Defining these endogenous sources of DNA damage or stresses is critical for understanding the pathogenesis of deficiencies for FA proteins. We propose that FA proteins are centrally involved in the response to replication stress, including replication stress arising from oxidative DNA damage.

    Full Text Available Dog poisoning toxicant used at home for rodent control (often based on zinc phosphide is accompanied by the development of anemia . In etiopathogenesis of this type of pathology of the blood we can highlight as important: haemolytic , haemorrhagic and allergic components, but the nature and extent of the changes under there are unequal. This requires the development of a special algorithm of examination and treatment strategies of the animal in accordance with the stages of the development of the disease. Modern conditions dictate the need, along with the actions to carry out urgent medical identification as the main etiological factor and pathogenesis, and the leading pathogenetic factors that pose a threat to the danger of other pathological processes and disease states. First, we evaluate the extent of damage to the liver, kidneys, heart, spleen and blood vessels, which is possible only if the clinic has appropriate methods and equipment. It is undeniable in this regard the importance of evidence-based recommendations for dietary nutrition of the affected animal's behavior after the clinic urgent remedial measures. The article proves high importance of evaluating the effectiveness of the treatment in the clinic

    Recent advances in the treatment of aplastic anemia (AA) made most of patients to expect to achieve a long-term survival. Allogeneic stem cell transplantation (SCT) from HLA-matched sibling donor (MSD-SCT) is a preferred first-line treatment option for younger patients with severe or very severe AA, whereas immunosuppressive treatment (IST) is an alternative option for others. Horse anti-thymocyte globuline (ATG) with cyclosporin A (CsA) had been a standard IST regimen with acceptable response rate. Recently, horse ATG had been not available and replaced with rabbit ATG in most countries. Subsequently, recent comparative studies showed that the outcomes of patients who received rabbit ATG/CsA were similar or inferior compared to those who received horse ATG/CsA. Therefore, further studies to improve the outcomes of IST, including additional eltrombopag, are necessary. On the other hand, the upper age limit of patients who are able to receive MSD-SCT as first-line treatment is a current issue because of favorable outcomes of MSD-SCT of older patients using fludarabine-based conditioning. In addition, further studies to improve the outcomes of patients who receive allogeneic SCT from alternative donors are needed. In this review, current issues and the newly emerging trends that may improve their outcomes in near futures will be discussed focusing the management of patients with AA.

    Full Text Available Autoimmune hemolytic anemia (AIHA is a rare disease with an estimated prevalence of around 17/100,000. It is often difficult to diagnose and treat AIHA, especially in elderly. A 60-year-old female was admitted with the complaints of low grade fever, on-off for 6 months, progressive fatigue and dyspnea on exertion. She was transfused with three units of blood within these 6 months. Examination revealed pallor, edema, hemic murmur, and palpable liver. Hb was 2.9 gm%, T Bil 5.2 mg/dl, ESR 160 mm, and reticulocyte count 44.05%. Direct Coombs test was positive, anti-nuclear antibody (ANA and Anti ds DNA were positive. A diagnosis of systemic lupus erythematosus (SLE with AIHA was considered and patient was transfused with two units of packed red cells and put on steroid (prednisolone at 1 mg/kg body weight daily. After 3 weeks, her Hb had increased to 10.4 gm% with gross clinical improvement.

    The major causes of iron deficiency anemia (IDA) include iron loss due to bleeding, increased iron requirements, and decreased iron absorption by the intestine. The most common cause of IDA in Japanese women is iron loss during menstruation. Autoimmune atrophic gastritis and Helicobacter pylori infection can also cause IDA by reducing intestinal iron absorption. In addition to these common etiologies, germline mutations of TMPRSS6 can cause iron-refractory IDA (IRIDA). TMPRSS6 encodes matriptase-2, a membrane-bound serine protease primarily expressed in the liver. Functional loss of matriptase-2 due to homozygous mutations results in an increase in the expression of hepcidin, which is the key regulator of systemic iron homeostasis. The serum hepcidin increase in turn leads to a decrease in iron supply from the intestine and macrophages to erythropoietic cells. IRIDA is microcytic and hypochromic, but decreased serum ferritin is not observed as in IDA. IRIDA is refractory to oral iron supplementation, but does respond to intravenous iron supplementation to some extent. Because genetic testing is required for the diagnoses of IRIDA, a considerable number of cases may go undiagnosed and may thus be overlooked.

    Progress is reported on studies on hereditary anemias of mice. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, each of which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse.

    Full Text Available This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living and IADL (instrumental activities of daily living. Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    Full Text Available Abstract Background HIV-associated anemia is common and associated with poor prognosis. However, its response to antiretroviral treatment (ART in rural Africa is poorly understood. Methods HIV-infected adults (≥15 years who enrolled in HIV care at Haydom Lutheran Hospital in northern Tanzania were included in the study. The effect of ART (zidovudine/stavudine + lamivudine + efavirenz/nevirapine on HIV-associated anemia was studied in a subset of patients who were anemic at the time they started ART and had a follow-up hemoglobin measurement 12 months later. Pregnant women were excluded from the study, as were women who had given birth within the past 6 weeks. Anemia was defined as hemoglobin Results At enrollment, mean hemoglobin was 10.3 g/dL, and 649 of 838 patients (77.4% were anemic. Of the anemic patients, 254 (39.1% had microcytosis and hypochromia. Among 102 patients who were anemic at ART initiation and had a follow-up hemoglobin measurement after 12 months, the mean hemoglobin increased by 2.5 g/dL (P Conclusions Most patients had anemia at enrollment, of whom nearly 40% had microcytosis and hypochromia suggestive of iron deficiency. The mean hemoglobin increased significantly in patients who received ART, but one third were still anemic 12 months after ART initiation indicating that additional interventions to treat HIV-associated anemia in rural Africa might be warranted, particularly in patients with microcytosis and those treated with zidovudine.

    Full Text Available Anemia is major public health problem affecting 1.6 billion people worldwide. The poor compliance of iron supplementation remains main contributor for high prevalence of anemia. The current paper reviewed the effectiveness of direct observation of oral iron supplementation on anemia. A systematic search was performed through electronic databases and local libraries. Search strategies used subject headings and key words “directly observed” and “iron supplementation.” Searches were sought through April 2014. A total of 14 articles were included in the study. Findings were presented in three categories. First, all of those reported an improvement in compliance of iron supplementation. Second, reduction in the prevalence of anemia was reported by all and third, all except one reported increased blood hemoglobin level. Directly observed an iron supplementation is an effective approach for prevention and management of anemia in vulnerable groups. However, larger trials are needed before concluding that scaling up directly observed iron supplementation through community health volunteers would be beneficial.

    Despite the improvement in some indicators of maternal health, the rate of anemia in pregnancy in South Sharqiya Region, Oman was not satisfactory. The aim of this work was to study the correlates of anemia in pregnancy and its outcomes at the ANC clinics in South Sharqiya health centers. A health facility-based follow up study was designed in 1998. In randomly selected 5 health centers representing all wilayats of South Sharqiya Region, Oman, a form for monthly data collection from the ANC registers was used to follow up 852 pregnant women till their pregnancies ended. Hemoglobin estimation was done four times monthly apart for pregnant women and data was entered into the computer using EPI info program. The data of 852 pregnant females was analyzed where 43.6% of the sample were anemic. Logistic Regression showed that mother age and weight were significantly associated with anemia in pregnancy. Follow up of pregnant anemic women was not satisfactory. Anemic pregnant women showed response to iron supplement and folic acid received. No significant association between anemia in pregnancy whatever its grade and LBW or still birth. The follow-up system of anemia in pregnancy should be stricter. Good dietary history has to be taken from pregnant females for better nutritional education and to rule out unhealthy nutritional practices.

A total of 302 children aged between 6 month to 5 years were enrolled in the survey. The study aimed at assessing the extention of parasitoses in preschool aged children. The relationship between the Giardiasis intestinalis and ferropenic anemia. The prevalence of anemia is 31.78% (n = 302). The parasitologic analysis has shown that 113 children out of 302 are infected; 37.41%. We observed an obvious predominance of Giardia Lamblia: 62% (n = 113) pathogenic protozoon. The rate of anemia parasited children is amounted to 19.78%. During the Giardiasis, anemia is present in 23.17% of the cases. The Polyparasitism concerns 16% of the infested children. This anemia could be caused by a global bad absorption syndrome or by a ferro-elective bad absorption. A proper sanitary education, a purification action and also a curative treatment of the beaners carriers will be the only guarantees to decrease its morbidity.

    Concern about environmental lead exposure as a significant public health threat has increased as evidence has accumulated regarding adverse health effects at successively lower levels. Aplastic anemia is a hematological disorder of unknown etiology with a high lethality rate. Lead is a known toxicant for the hematopoietic system. Oxidative stress appears to be the possible mode of lead toxicity. We evaluated the effects of blood lead level on oxidative stress parameters in children suffering from aplastic anemia disease. Seventeen children with aplastic anemia disease (15 male and 2 female, age 3-12 y) were recruited in the study group. Fifty one healthy children (45 male and 6 female, age 3-12 y) having normal blood profiles and not suffering from any chronic disease(s) were used as controls. Blood lead level and oxidative stress parameters were determined. Mean blood lead level was significantly higher while δ-aminolevulinic acid dehydratase (δ-ALAD) activity, a biomarker for lead exposure was significantly lower in the study group as compared to the control group (p lead levels with δ-ALAD (r = -0.45; p lead induces oxidative stress in children suffering from aplastic anemia. Lead-induced oxidative stress as an underlying mechanism for aplastic anemia warrants further research.

    The basic purpose of this study is the delineation and exploitation of inborn anemias of the laboratory mouse, carried out by utilization of genetically homogeneous stocks segregating only for anemia-producing genes; by physiological and histological descriptions of each condition at all stages in the life history; by determination of tissue sites of primary gene action through tissue culture studies, tissue transplantation and parabiosis experiments; by analysis of reactions of normal and anemic mice to a variety of stressful stimuli, including x-irradiation, hypoxia, and toxic chemicals, and by biochemical comparisons between tissues, especially erythrocytes and hemopoietic cells of normal vs each type of anemic mouse. At present 16 single-locus anemias are known in the mouse, plus one with multifactorial inheritance (the autoimmune hemolytic anemia of NZB inbred mice). Of these, six are maintained only by the Jackson Laboratory, and two others have but one additional source. Effects of anemia-producing mutant alleles of these loci (an; f; ja; ha; Hba/sup th/; mk; nb; Sl and Sl/sup d/; sla; sph; and W, W/sup v/, W/sup J/ and 10 other putative W-alleles) are currently under investigation at the Jackson Laboratory. 15 refs.

    Iron deficiency anemia (IDA) continues to be major public health problem in India. It is estimated that about 20% of maternal deaths are directly related to anemia and another 50% of maternal deaths are associated with it. The question, therefore, is why, despite being the first country to launch the National Nutritional Anemia Prophylaxis Programme in 1970, the problem of IDA remains so widespread. As is to be expected, the economic implications of IDA are also massive. The issues of control of IDA in India are multiple. Inadequate dietary intake of iron, defective iron absorption, increased iron requirements due to repeated pregnancies and lactation, poor iron reserves at birth, timing of umbilical cord clamping, timing and type of complementary food introduction, frequency of infections in children, and excessive physiological blood loss during adolescence and pregnancy are some of the causes responsible for the high prevalence of anemia in India. In addition, there are other multiple programmatic and organizational issues. This review, therefore, is an attempt to examine the current burden of anemia in India, its epidemiology, and the various issues regarding its prevention and control, as well as to offer some innovative approaches to deal with this major health problem.

    Four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an ..cap alpha..-thalassemia, and a new target-cell anemia are under investigation in mice. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus the wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse. Each anemia is studied through: (a) characterization of peripheral blood values; (b) determinations of radiosensitivity under a variety of conditions; (c) measurements of iron metabolism and heme synthesis; (d) histological and biochemical study of blood-forming tissue; (e) functional tests of the stem cell component; (f) examination of responses to erythroid stimuli; and (g) transplantation of tissue between individuals of differently affected genotypes.

    Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovarian teratoma. A 25-yr-old woman complained of general weakness and dizziness for 1 week. The hemoglobi...

    The association of gastrointestinal malignancy with aplastic anemia has rarely been reported in the literature. Although it is not clear whether there is any direct relationship between aplastic anemia and gastrointestinal cancers, a retrospective analysis did suggest the notion that patients with aplastic anemia might have a higher incidence of colorectal cancer. Here, we report the diagnostic and therapeutic challenges in managing a patient with aplastic anemia and advanced colorectal cance...

  19. Clonal hematopoiesis in acquired aplastic anemia

    Science.gov (United States)

    2016-01-01

    Clonal hematopoiesis (CH) in aplastic anemia (AA) has been closely linked to the evolution of late clonal disorders, including paroxysmal nocturnal hemoglobinuria and myelodysplastic syndromes (MDS)/acute myeloid leukemia (AML), which are common complications after successful immunosuppressive therapy (IST). With the advent of high-throughput sequencing of recent years, the molecular aspect of CH in AA has been clarified by comprehensive detection of somatic mutations that drive clonal evolution. Genetic abnormalities are found in ∼50% of patients with AA and, except for PIGA mutations and copy-neutral loss-of-heterozygosity, or uniparental disomy (UPD) in 6p (6pUPD), are most frequently represented by mutations involving genes commonly mutated in myeloid malignancies, including DNMT3A, ASXL1, and BCOR/BCORL1. Mutations exhibit distinct chronological profiles and clinical impacts. BCOR/BCORL1 and PIGA mutations tend to disappear or show stable clone size and predict a better response to IST and a significantly better clinical outcome compared with mutations in DNMT3A, ASXL1, and other genes, which are likely to increase their clone size, are associated with a faster progression to MDS/AML, and predict an unfavorable survival. High frequency of 6pUPD and overrepresentation of PIGA and BCOR/BCORL1 mutations are unique to AA, suggesting the role of autoimmunity in clonal selection. By contrast, DNMT3A and ASXL1 mutations, also commonly seen in CH in the general population, indicate a close link to CH in the aged bone marrow, in terms of the mechanism for selection. Detection and close monitoring of somatic mutations/evolution may help with prediction and diagnosis of clonal evolution of MDS/AML and better management of patients with AA. PMID:27121470

    Full Text Available Autoimmune hemolytic anemia (AIHA is not an uncommon clinical disorder and requires advanced, efficient immunohematological and transfusion support. Many AIHA patients have underlying disorder and therefore, it is incumbent upon the clinician to investigate these patients in detail, as the underlying condition can be of a serious nature such as lymphoproliferative disorder or connective tissue disorder. Despite advances in transfusion medicine, simple immunohematological test such as direct antiglobulin test (DAT still remains the diagnostic hallmark of AIHA. The sensitive gel technology has enabled the immunohematologist not only to diagnose serologically such patients, but also to characterize red cell bound autoantibodies with regard to their class, subclass and titer in a rapid and simplified way. Detailed characterization of autoantibodies is important, as there is a relationship between in vivo hemolysis and strength of DAT; red cell bound multiple immunoglobulins, immunoglobulin G subclass and titer. Transfusing AIHA patient is a challenge to the immunohematologist as it is encountered with difficulties in ABO grouping and cross matching requiring specialized serological tests such as alloadsorption or autoadsorption. At times, it may be almost impossible to find a fully matched unit to transfuse these patients. However, transfusion should not be withheld in a critically ill patient even in the absence of compatible blood. The "best match" or "least incompatible units" can be transfused to such patients under close supervision without any serious side-effects. All blood banks should have the facilities to perform the necessary investigations required to issue "best match" packed red blood cells in AIHA. Specialized techniques such as elution and adsorption, which at times are helpful in enhancing blood safety in AIHA should be established in all transfusion services.
