Although its etiology is understood and intervention at low cost is available, the problem persists. The present review begins with a general estimate of the dimensions of the problem. It suggests the necessary elements for the design, implementation, and measurement of the impact of iron supplementing and fortification as the most effective forms to intervene and diminish iron deficiency anemia. Several preliminary steps are proposed previous to the preparation of a project and several recomendations are made to be included in a project for fortification and iron supplementing. A list of complementary activities offered by PAHO/WHO as part of the package of technical cooperation is included.

    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. Es necesario evaluar las estrategias de intervención y hacer estudios consistentes que permitan tomar las medidas adecuadas para controlarla.OBJECTIVE: To describe the prevalence of iron deficiency anemia in the past 66 years among Mexican women on reproductive age, and to analyze the efficacy of interventions implemented for its prevention and control.

    Full Text Available Inherited erythrocytic pyruvate kinase (PK deficiency is an autosomal recessive hemolytic disorder described in dogs and cats. Pyruvate kinase is one of two key-regulatory enzymes in the anaerobic glycolytic pathway, and its deficiency causes premature destruction of the ATP-depleted red cells. This case study reports the clinical and laboratory findings in a West Highland White Terrier (WHWT dog with a life-long history of weakness and exercise intolerance from Brazil. The dog was found to have persistently profound pallor, a highly regenerative hemolytic anemia and osteosclerosis. PK deficiency was confirmed by a breed-specific DNA test for the previously described 6 bp insertion at 3' end of exon 10 in red blood cell (RBC R- PK gene sequence. The dog was euthanized at 20 months of age due to the deterioration of its clinical condition including anemia and blood incompatibility. Other PK-deficient WHWTs have lived as long as 9 years. Hereditary red cell defects are important differential diagnoses for chronic hemolytic anemias in younger animals after excluding immune-mediated and infectious causes. Furthermore, purebred dogs for which DNA tests for hereditary diseases are available should be screened prior to breeding in order to limit the spread of the mutant allele and to avoid future production of PK-deficient animals.La deficiencia de piruvato quinasa (PK es un desorden hemolítico autosómico recesivo descrito en perros y gatos.

    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 La deficiencia de hierro es una de las deficiencias de micronutrientes más comunes. Los adolescentes son un grupo vulnerable. Un reconocimiento oportuno puede prevenir una anemia ferropénica, etapa final y grave de dicha deficiencia, insuficientemente conocida en nuestro país. El objetivo de este estudio fue determinar los valores hematológicos en adolescentes y conocer las prevalencias de anemia y deficiencia de hierro. Definidas como a anemia: hematocrito (Hto Iron deficiency is highly frequent among adolescents. Its early detection can prevent the development of a ferropenic anemia, a serious condition. The problem has not been well studied in our country. The purpose of this work was to determine the frequency of iron deficiency and anemia in adolescents. The criteria considered were: hematocrit below 38%, b saturation transferrin below 16%, c ferritin below 15 ng/ml. The study was carried out in 2.265 schoolchildren, 12 years old, of both sexes, in urban and periurban areas in the city of San Salvador de Jujuy (1.250 a.s.l.. The following parameters were measured: hematocrit as well as serum iron and total iron binding capacity, both by colorimetric method. Ferritin was measured by ELISA. Anemia was not found. Iron deficiency as estimated by the iron functional component, was found in 25% of girls and 21% of boys and, through iron stores, in 28% of girls and 18% of boys. Iron deficiency stores in both sexes is the more relevant alteration, indicating that the population sample here studied constitutes a highly vulnerable group. The early detection of iron deficiency will help physical and intellectual development so that adequate sanitary policies are necessary for its prevention.

La alta frecuencia de donantes de sangre con deficiencia de hierro encontrada en este estudio sugiere la necesidad de pruebas de laboratorio más exactas. La determinación de hemoglobina únicamente no es suficiente para encontrar y excluir donantes de sangre con deficiencia de hierro sin anemia y los ajustes hacia niveles más altos de los criterios de aceptación de hemoglobina no contribuye a mejorar la situación comprometiendo el suministro de sangre, al pasar la exclusión de donantes por hemoglobina baja de 9% en la actualidad a 44.6%.

    up to 1000 mg can be given in a single session, thus providing an excellent tool to avoid or treat iron deficiency in this patient population.La inflamación crónica inducida por la obesidad provoca alteraciones en la homeostasis del hierro, incluyendo hiposideremia, restricción del hierro para la eritropoyesis y anemia leve o moderada. Consecuentemente, la anemia y la deficiencia de hierro son frecuentes entre los pacientes candidatos a cirugía bariátrica (CB. El estudio preoperatorio debe incluir un hemograma completo y la evaluación del status férrico, vitamina B12 y ácido fólico. Se recomienda realizar un estudio gastrointestinal en la mayoría paciente con anemia ferropénica. Ante una anemia inexplicada, debería postergarse la cirugía hasta que se haya realizado un diagnóstico apropiado. La anemia perioperatoria se ha relacionado con aumento de morbi-mortalidad postoperatoria y disminución de la calidad de vida después de una cirugía mayor, mientras que la corrección de la anemia y la deficiencia de micronutrientes (hierro, vitamina B12, folato mejoran el pronóstico y la calidad de vida. Sin embargo, no existen estudios de seguimiento a largo plazo en lo que respecta a la prevalencia, gravedad y causas de la anemia en pacientes CB. Tras la CB, los pacientes deben recibir suplementos de hierro, pero la tolerancia al hierro oral no es buena; una vez instaurada la situación de ferropenia, ésta podría ser refractaria al tratamiento oral. En estas situaciones, el uso de preparados IV (que evitan el bloqueo del hierro en enterocitos y macrófagos ha surgido como una alternativa segura y efectiva en el tratamiento de la anemia perioperatoria. Los nuevos preparados de hierro IV, como la carboximaltosa férrica, son seguros, fáciles de utilizar y permiten administrar hasta 1.000 mg en una sola sesión, proporcionando así una excelente herramienta para tratar o prevenir el déficit de hierro en estos pacientes.

    Full Text Available Embora o ferro por via oral seja considerado a primeira opção de tratamento da deficiência de ferro, em algumas situações específicas, a administração de ferro por via parenteral é uma opção terapêutica que deve ser considerada. Diferentemente do ferro dextran de alto peso molecular utilizado na década de 80 e lembrado como um composto associado ao alto risco de reação anafilática e morte, o desenvolvimento e comercialização de novos compostos com ferro para uso parenteral, sobretudo por via endovenosa - como o ferro sacarato, ferro gluconato e, mais recentemente, a carboximaltose férrica - , tem se tornado cada vez mais uma alternativa terapêutica segura e efetiva, e tem possibilitado ampliar o leque de indicações desta modalidade de tratamento além da nefrologia, como obstetrícia e ginecologia, cirurgia, pediatria, gastroenterologia, hematologia e hemoterapia. Os autores revisam as principais indicações do tratamento com ferro por via parenteral, analisam as principais drogas disponíveis para a correção da anemia ferropriva por via endovenosa e propõem uma estratégia de investigação diagnóstica, tratamento e seguimento laboratorial dos pacientes com indicação desta opção terapêutica.Although oral iron is generally considered the first choice in the treatment of iron deficiency, in some specific situations, parenteral iron administration is a therapeutic option that should be considered. Different to the high-molecular-weight iron dextran utilized in the eighties and remembered as a compound associated with a high risk of anaphylaxis and death, the development and marketing of newer preparations for parenteral, in particular endovenous, administration, such as iron sucrose, ferric gluconate and more recently ferric carboxymaltose, are becoming a more effective and safe therapeutic alternative, that have extended the range of indications beyond nephrology to obstetrics and gynecology, surgery, pediatrics

    Full Text Available El objetivo de este estudio fue conocer y comprender la orientación sexual proveniente de madres de hijos portadores de deficiencia visual. Bajo la perspectiva fenomenológica, se analizan veinte discursos de madres de deficientes visuales. El recorrido por todos los discursos permite conocer que la desinformación sobre la sexualidad en general, impide el diálogo entre madre e hijo(a. Tales recorridos evidencian igualmente, que la represión sexual fundamenta los estigmas y los preconceptos en la educación sexual de los deficientes visuales. The objective of this study is to analyze and understand the sexual orientation given by mothers to sons and daughters with visual deficiencies. From a phenomenological perspective the narratives of twenty mothers of visual defficients are analyzed. The convergences of these conversations make clear that disinformation about sexuality in general impedes dialogues between mothers and offspring. Evidence was obtained showing that sexual repression stems from stigmas and preconcepts about sexual education of persons with visual defficiencies.

    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.

No es frecuente dentro de la historia natural de la hepatitis A, la aparición de anemia hemolítica, y cuando se presenta, generalmente se asocia a deficiencia de glucosa-6-fosfato deshidrogenasa. Presentamos el caso de un paciente de sexo masculino sin hemólisis previa, con astenia e ictericia de dos meses de evolución y hepatomegalia 14 cm por debajo del reborde costal derecho. Los hallazgos en los exámenes de laboratorios mostraron anemia hemolítica con Coombs directo positivo, anticuerpos tipo inmunoglobulina M contra el virus de la hepatitis A positivos, niveles de bilirrubinas 20 veces y aminotrasferasas cuatro veces por arriba del rango normal; con estos datos el paciente fue diagnosticado como hepatitis A complicada con anemia hemolítica y probable hepatitis autoinmune asociada, por lo que se inició manejo con corticoides, alcanzándose mejoría clínica. Resaltamos la importancia de descartar la infección por el virus de la hepatitis A como posible etiología de anemia hemolítica autoinmune.______________________________________________________________________ Acute auto inmune haemolytic anaemia is associated with a variety of hepatotropic viruses, in particular cytomegalovirus, Epstein Barr virus and hepatitis B.

Luego del destete, las crías macho se asignaron al azar a dos grupos que recibieron una dieta control o una baja en cinc durante 60 días.ResultadosLos resultados mostraron que el aporte insuficiente de cinc durante el crecimiento previo y/o posterior al destete indujo un aumento de la presión arterial y una disminución del volumen de filtrado glomerular en la vida adulta, asociados con una disminución del sistema del óxido nítrico renal y vascular. Además, el bajo aporte de este mineral durante la vida fetal indujo un peso menor al nacer, que se correlacionó en forma negativa con la presión arterial en la vida adulta.ConclusionesEste trabajo brinda evidencias importantes que sugieren que el aporte inadecuado de cinc durante el crecimiento prenatal y posnatal constituye un factor de riesgo cardiovascular y renal, dado que induce alteraciones en la regulación de la presión arterial y en la función renal en el individuo adulto.REV ARGENT CARDIOL 2008;76:459-464.

    Full Text Available El presente trabajo tiene por objeto revisar los aspectos teóricos y los estudios realizados en México que sugieren la existencia de la deficiencia moderada de zinc en niños de población rural, así como algunas de las consecuencias de dicha deficiencia en la salud. El zinc es un nutrimento indispensable para el organismo de los humanos y juega un papel importante en una serie de procesos metabólicos: participa en el sitio catalítico de varios sistemas enzimáticos; participa como ion estructural en membranas biológicas, y guarda una estrecha relación con la síntesis de proteínas, entre otras cosas. Es por esto que la deficiencia de zinc está asociada con consecuencias importantes en la salud y la funcionalidad de los individuos, especialmente durante las primeras etapas de la vida. De relevancia para México es la existencia de una deficiencia moderada de zinc en los niños y las consecuencias que ésta pueda tener en la salud de los mismos. Los estudios realizados sugieren que la deficiencia moderada de zinc se presenta asociada con la ingestión de dietas basadas en alimentos de origen vegetal, las cuales contienen cantidades importantes de inhibidores de la absorción de zinc. Este tipo de dietas se consume habitualmente en las zonas rurales y en la población marginal de las ciudades en el país. Entre las consecuencias más importantes de esta deficiencia se encontró un aumento en la presencia de enfermedades infecciosas, especialmente de diarrea, y posibles alteraciones en el desarrollo de la capacidad cognoscitiva.

    Full Text Available La deficiencia de hierro afecta a mas de 2000 millones de personas en el mundo entero. Una de sus consecuencias son las alteraciones en el desarrollo cognoscitivo. El presente trabajo tuvo como objetivos describir los aspectos mas importantes del metabolismo de hierro en el hombre y especialmente en el cerebro, los mecanismos fisiológicos por los cuales la deficiencia de hierro puede causar afectaciones en el sistema nervioso central (SNC de niños y adolescentes, algunos de los estudios que demuestran la relación entre las afectaciones en el desarrollo neural y la deficiencia de hierro, así como las principales estrategias de nuestro país para combatir este trastorno nutricional. La deficiencia de hierro ocasiona hipomielinización, lo cual origina neuronas deficientes. Por otra parte está asociada con la alteración en varios procesos metabólicos que impartan en el adecuado funcionamiento cerebral, como son el transporte de electrones y la síntesis de neurotransmisores. Numerosos estudios realizados en bebes, niños en edad escolar y adolescentes evidencian el retardo en el aprendizaje de niños anémicos con respecto a los no anémicos, así como afectaciones en el sistema visual y auditivo. En nuestro país se utilizan las sales ferrosas y el biopreparado hierro ¿ proteína, Trofín para la prevención y tratamiento de la deficiencia de hierro, sin embargo las estrategias para combatir esta deficiencia, aún son insuficientes.

    Full Text Available La anemia de Fanconi es una patología genética caracterizada por una alteración en la reparación del ADN que se expresa con alteraciones físicas y hematológicas. Es una enfermedad congénita rara y corresponde a la primera causa de anemia aplásica en la infancia. Tiene un curso desfavorable tanto por el deterioro de sus parámetros sanguíneos, así como también por el riesgo aumentado de malignización hematológica. Su único tratamiento curativo es el trasplante de médula ósea. Se presenta el caso de un niño de 3 años, hijo de padres judíos, portador de malformaciones mayores y menores, que presentó un cuadro infeccioso por Mycoplasma pneumoniae que evolucionó a una pancitopenia severa. En el  estudio del caso se buscaron etiologías  que abarcaron desde las infecciosas e inmunológicas hasta  las que involucraban a la medula ósea Una vez que los exámenes realizados descartaron patologías linfoproliferativas, la clínica y la persistencia del cuadro orientaron a buscar alguna condición genética que explicara esta situación.

    Full Text Available El propósito de este trabajo es el de presentar un análisis comparativo de los resultados de seis investigaciones en las cuales ha participado el autor sobre la relación entre la deficiencia de hierro y el funcionamiento intelectual. Las investigaciones fueron realizadas en Egipto, Estados Unidos, Guatemala, Indonesia y Tailandia entre niños de edad pre-escolar. La deficiencia de hierro con anemia está entre las dos deficiencias nutricionales más prevalentes en el mundo y es de esperar que su prevalencia sea alta en el Perú, particularmente entre los infantes y niños y entre las madres gestantes y lactantes. Una de las causas importantes es el limitado consumo de alimentos ricos en hierro hemínico que generalmente son muy costosos para los grupos más pobres de la sociedad. El análisis comparativo muestra que los resultados son consistentes a través de los seis estudios y que la deficiencia de hierro con anemia afecta el rendimiento en las pruebas de procesos cognoscitivos específicos y en las pruebas de rendimiento escolar. Los resultados también muestran que dichos efectos son reversibles con el tratamiento apropiado. A su vez, el análisis muestra que no hay evidencia suficiente para inferir que la deficiencia de hierro sin anemia afecta el cociente intelectual.   The purpose of this paper is to present a comparative analysis of the results of six researches in which the author has participated, about the relation between iron deficiency and intellectual performance. The researches were carried out in Egypt, U.S.A., Guatemala, Indonesia and Thailand, with pre-school and school children. Iron deficiency with anemia are among the two nutritional deficiencies of major prevalence in the word and it must be expected that the same goes for Peru. One of the causes of the low consuming of food rich in iron is that these are too expensive for groups of low socioeconomic level. The comparative analysis shows consistent results in the six

    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 El hierro es un metal esencial para la vida, pero en cantidades elevadas resulta tóxico. La regulación del metabolismo del hierro es actualmente un tema de intensa investigación al haberse descrito el papel clave de la hepcidina, hormona cuyo gen HAMP está muy conservado. Las alteraciones del metabolismo del hierro dan lugar a sobrecarga, destacando la hemocromatosis hereditaria clasificada como enfermedad rara, o en el otro extremo deficiencia de hierro y anemia ferropénica que constituyen un problema de Salud Pública de proporciones mundiales. Las variantes genéticas implicadas en sobrecarga y deficiencia de hierro se han centrado en los genes HFE, TFR2, HAMP, HJV, Tf y TMPRSS6. El hierro tiene la capacidad de ceder o donar electrones con facilidad y puede catalizar reacciones vía radicales libres e incrementar el estrés oxidativo. Así, la peroxidación lipídica y riesgo cardiovascular son consecuencias de la sobrecarga de hierro. Recientemente, se ha descrito también una relación entre el metabolismo del hierro y la resistencia a la insulina y la obesidad. Por el contrario, aún existe gran controversia en cuanto a la relación anemia ferropénica-enfermedad cardiovascular. Esta revisión presenta de forma breve los conocimientos actuales sobre la regulación del metabolismo del hierro, su biodisponibilidad y los trastornos por sobrecarga y deficiencia de hierro, para posteriormente examinar las relaciones existentes entre el hierro y el riesgo cardiovascular, tanto en la deficiencia como en la sobrecarga. Finalmente presenta propuestas para desde la nutrición utilizar estrategias para paliar la sobrecarga o prevenir la anemia por falta de hierro.Although iron is an essential mineral for maintaining good health, excessive amounts are toxic. Nowadays, much interest is focused on the mechanisms and regulation of iron metabolism by down-regulation of the hormone hepcidin. The HAMP gene encodes for hepcidin appears to be

    Full Text Available A anemia por deficiência de ferro caracteriza-se como o mais prevalente problema nutricional em todo o mundo. Nesta revisão reuniu-se informações a respeito do metabolismo da hepcidina, avaliando-se seu valor como parâmetro bioquímico na anemia por deficiência de ferro. Realizou-se um levantamento bibliográfico nas bases de dados PUBMED e LILACS, período 2006-2010, referentes à hepcidina como um biomarcador para a regulação do metabolismo do ferro. Foram localizados 35 estudos publicados em revistas internacionais e um estudo sobre o assunto em revista nacional. A produção de hepcidina é regulada homeostaticamente pela anemia e hipóxia. Quando a oferta de oxigênio está inadequada ocorre diminuição do nível de hepcidina. Consequentemente, maior quantidade de ferro proveniente da dieta e dos estoques dos macrófagos e hepatócitos se tornam disponíveis. A hepcidina possui a função de se ligar à ferroportina, regulando a liberação do ferro para o plasma. Quando as concentrações de hepcidina estão baixas, as moléculas de ferroportina são expostas na membrana plasmática e liberam o ferro. Quando os níveis de hepcidina aumentam, a hepcidina liga-se às moléculas de ferroportina induzindo sua internalização e degradação, e o ferro liberado diminui progressivamente. Aparentemente o desenvolvimento do diagnóstico e terapia da anemia baseados no bioindicador hepcidina pode oferecer uma abordagem mais efetiva. Estudos epidemiológicos são necessários para comprovar o valor da hepcidina no diagnóstico diferencial das anemias, incluindo protocolos de amostragem para análise, com padronização similar às utilizadas em outras avaliações bioquímicas, e estabelecimento de pontos de corte para a expressão urinária e plasmática desse peptídeo.Iron deficiency anemia is the most prevalent nutritional problem in the world.

    Full Text Available Benzoato de estradiol aplicado em altas doses a cães tem uma ação essencialmente trombocitopênica e o mecanismo de formação da anemia que se estabelece é semelhante ao observado na anemia da purpura experimental pelo sôro anti-plaqueta. O quadro patológico é, em ambos os casos, resultante desta trombocitopenia aguda.The paper stresses the similarity between pathological changes produced in dogs by estradiol benzoate and anti-platelet serum. Estradiol benzoate when administered in large doses (0.1 mg per kilo produces primarily a thrombocytopenia after a short period (4 to 6 days. As a consequence of the lack of platelets in circulation (1/3 to 1/10 from the normal volume, a picture of purpura appears with predominance of intestinal hemorrhages followed by severe anemia (8 to 15 days. When active anti-platelet serum is administered a thrombocytopenia is rapidly obtained (12 to 48 hours. Intestinal purpuric lesions are very conspicuous and hemorrhages with acute anemia are always present. These results show the identity of the mechanism of anemia produced by estradiol benzoate and anti-platelet serum. The pratical value of determinations of occult blood in feces of patients with thrombocytopenic purpura is emphasized, as an aid to diagnosis and observation od crises of the Werlhof's disease.

Oe este sistema hacen parte varias proteínas; un flavocitocromo b558' el cual está conformado por una cadena b (gp91-phox y una cadena a (p22-phox y poral menos 3 proteínas citosólicas (p47-phox, p67- phox, p40-phox. Una alteración gen ética en cualquiera de estas proteínas causa el síndrome de Enfermedad Granulomatosa Crónica (EGC. La caracterizaciÓn de las mutaciones de los pacientes con EGC ha sido fundamental para dilucidar la estructura y función de los componentes del sistema NAOPH oxidasa. En el caso de la p47-phox, se han obtenido hallazgos importantes que la hacen un modelo interesante para estudiar el mecanismo molecular involucrado en regular la expresión y función bioquímica de este sistema. En los pacientes con defecto en la p47-phox investigados hasta ahora, se ha hallado una deleción del dinucleótido GT al comienzo del exón 2 , siendo la mayoría de ellos homocigóticos para esta deleción, la cual posiblemente se debe a eventos de recombinación entre el gen p47 -phox normal y un seudogen recientemente descrito. En el diagnóstico de pacientes no homocigóticos, cualquier mutación encontrada en el análisis del ONA (gONA o cONA puede representar un cambio sufrido por el seudogen. Por lo tanto, para la identificación precisa del defecto gen ético es necesario separar el gen normal del seudogen y analizar las secuencias en forma individual. Los pacientes no homocigóticos posiblemente deben tener una segunda mutación en el alelo tipo silvestre diferente a la deleción GT. De otro lado, a través de mutagénesis sitio-dirigida se pueden modificar algunos de los aminoácidos o dominios de la p47-phox, los cuales pueden ser esenciales para su funcionamiento y su relación con la EGC. Con esta metodología, es posible introducir cambios en un gen cuya secuencia es totalmente conocida, el cual es amplificado; las mutantes así generadas pueden dar información acerca

Se caracteriza por la disminución o ausencia de los depósitos de hierro. La prueba deficiencia que confirma la existencia de anemia por déficit de hierro (AF son unos niveles séricos bajos de ferritina, indicativos de una situación de depleción de hierro. Otros parámetros no permiten diferenciar la AF de la anemia trastornos crónicos. La dieta es de gran importancia en la anemia, sin embargo, ningún alimento contiene concentraciones suficientes de hierro para poder constituir un remedio práctico en los estados de carencia del mismo, por lo que el tratamiento debe realizarse por vía oral con preparados a poder ser a base de sulfato ferroso para asegurar una mejor absorción. Se recomienda una dosis inicial de 150-200 mg. de hierro elemental al día, repartido en tres tomas (3-5 mg/kg/día en niños.Anemia secondary to iron deficiency is the most frequent anaemia in our environment, the first cause of consultation in Haematology and the most common nutritional problem. It is characterized by a diminution or absence of iron deposits. The ultimate test that confirms the diagnosis of anaemia secondary to iron deficiency is a low serum level of ferritin, which indicates iron depletion. Other parameters do not allow to distinguish iron deficiency anaemia from other chronic derangements. Diet is of utmost importance in anaemia. There is not a single food product with sufficient concentration of iron capable of restoring iron deficiency situations. Therefore, treatment of iron deficiency must be made orally with iron preparates, mainly in the form of iron sulphate in order to guarantee a better absorption. The initial recommended doses are 150-200 mg of elemental iron per day split in three ingestions (in children 3-5 mg/Kg/day.

    Full Text Available La anemia perniciosa es la causa más frecuente de anemia megaloblástica en nuestro medio y es consecuencia de una deficiencia de vitamina B12 debido a su vez a la disminución o ausencia de factor intrínseco (FI por atrofia de la mucosa gástrica o por destrucción autoinmune de las células parietales productoras de éste. Ante la existencia de una atrofia gástrica intensa, se origina un descenso en la producción de ácido y FI y una posterior alteración en la absorción de vitamina B12. En un 50% de los casos se asocia a anticuerpos anti FI, cuya presencia en otras enfermedades auto-inmunes es excepcional. En pacientes con anemia perniciosa la determinación de anticuerpos anti FI tiene una alta especificidad (95%, sin embargo, la determinación de anticuerpos anticélulas parietales cuentan con una especificidad baja. El tratamiento de elección es la administración de B12 intramuscularmente. La pauta consiste en administrar 1 mg. de Vitamina B12 diariamente durante una semana, posteriormente semanal durante un mes y después cada 2-3 meses de por vida.Pernicious anemia is the most frequent cause of megaloblastic anemia in our area, and it is the result of a vitamin B12 deficiency due, itself, to the de-crease or absence of intrinsic factor (IF because of gastric mucosa atrophy or autoimmune destruction of IF-producing parietal cells. With the existence of a severe gastric atrophy, there is a decrease in acid and IF production and a further change in vitamin B12 absorption. Fifty percent of the cases are associated to anti-IF antibodies, which presence in other autoimmune diseases is exceptional. In patients with pernicious anemia, measurement of anti-IF antibodies has high specificity (95%; however, measurement of anti-parietal cells antibodies has low specificity.

    Full Text Available Resumo: O controle das endoparasitoses gastrintestinais em pequenos ruminantes tem sido tradicionalmente realizado por meio do uso indiscriminado dos anti-helmínticos, porém essa prática tem resultado em grande pressão de seleção de parasitas resistentes. Métodos seletivos (ex: FAMACHA/FMC e contagem de ovos nas fezes/OPG e que apresentem boa sensibilidade para identificar os animais que necessitam receber o tratamento químico são importantes alternativas aos métodos tradicionais. O objetivo desse trabalho foi determinar a sensibilidade e a especificidade do método FMC, usado para detectar anemia causada por Haemonchus contortus em ovinos da raça Suffolk, em duas categorias de alta suscetibilidade; cordeiros lactentes e ovelhas durante a fase de lactação. A conjuntiva ocular de 42 cordeiros lactentes e 35 ovelhas em lactação foi avaliada usando o método FMC, em intervalos de 14 dias, durante cinco meses. O hematócrito (Ht foi utilizado como padrão-ouro para avaliação clínica de anemia dos animais. Para o cálculo de sensibilidade e especificidade, diferentes critérios foram utilizados: animais classificados como 4 e 5 ou 3, 4 e 5 e anêmicos pelo Ht (teste positivo; animais classificados como 1, 2 e 3 ou 1 e 2 e não anêmicos pelo Ht (teste negativo. Três valores de corte para Ht (≤22%, ≤19% ou ≤15% foram utilizados para confirmar a anemia. Entre os gêneros observados nas coproculturas, H. contortus (61,5% e Ostertagiasp (21,3% foram os mais prevalentes. Em ambas as categorias, a inclusão do FMC 3 como teste positivo, elevou a sensibilidade mas reduziu a especificidade do método. Quando o FMC 3 foi considerado anêmico, o percentual de falsos negativos foi próximo a zero, no entanto, houve aumento no número de tratamentos aplicados em animais não anêmicos (falso positivo. Durante as avaliações, a maior parte dos cordeiros (73% e das ovelhas (53% permaneceu nas categorias de FMC 1 e 2. Apenas 5% dos

    Full Text Available OBJETIVO: avaliar, em grávidas adolescentes, a incidência de redução do estoque de ferro, por meio de seus vários indicadores: hemoglobina, ferro sérico, ferritina, índice de saturação de transferrina e receptor de transferrina, e correlacionar os seus resultados. MÉTODOS: foram incluídas 56 adolescentes, que se encontravam na primeira consulta de pré-natal entre a 12ª e a 20ª semana de gestação. Foram consideradas pacientes normais aquelas que apresentavam valores superiores a: 11 mg/dl para a hemoglobina, 12 mig/dL para a ferritina, 50 mg/L para o ferro sérico, 16% para o índice de saturação de transferrina e inferior a 28,1 nmol/L para o receptor de transferrina. Cada marcador foi avaliado por porcentagem simples e para verificar discordâncias entre os valores obtidos utilizamos o teste de McNemar. RESULTADOS: a incidência de anemia dada pelo nível de hemoglobina foi de 21,4%, sendo essas gestantes anêmicas, portadoras de anemia de grau leve. A ferritina em níveis inferiores a 12 µg/dL apurou deficiência de ferro em 21,4% das gestantes. O ferro sérico encontrou-se diminuído em 3,6% das pacientes e o índice de saturação da transferrina em 26,8% da amostra. Não se pôde valorizar a interpretação do receptor de transferrina, pois não há padronização internacional quanto à unidade de medida de dosagem. Quando se comparou a hemoglobina com os outros parâmetros de avaliação de ferropenia, como a ferritina, o ferro sérico, o índice de saturação de transferrina e o receptor de transferrina, encontrou-se que esses índices não avaliaram melhor que a hemoglobina a deficiência de ferro. CONCLUSÕES: a dosagem de hemoglobina, em pacientes com anemia leve, foi suficiente para avaliação da ferropenia.PURPOSE: to evaluate, in pregnant adolescents, the incidence of iron deficiency, using the following blood tests: hemoglobin, ferritin, serum iron, transferrin saturation rate and serum transferrin receptor

    Full Text Available Objetivou-se avaliar a progressão da doença e o dano oxidativo em cabras com anemia e doença respiratória mediante aplicação de ferro parenteral. Foram estudadas seis cabras, adultas, com parâmetros eritrocitários indicativos e anemia e manifestações de doença respiratória (tosse, espirros e secreção nasal. O grupo controle foi composto por seis cabras adultas, sadias. As cabras de ambos os grupos após serem submetidos à avaliação clínica receberam dose similar (0,5g de hidróxido férrico em complexo dextrânico, por via intramuscular. Amostras de sangue colhidas com EDTA, antes da aplicação do ferro e 48 horas depois foram utilizadas para determinação da concentração de substâncias reativas ao ácido tiobarbitúrico (TBARS. Nas cabras doentes antes da aplicação do ferro os valores de TBARS foram equivalentes aos valores mensurados nos controles antes e após a aplicação do ferro (p>0,05. Os valores mensurados nas cabras doentes foram muito mais elevados (p<0,001 no mesmo grupo de animais depois da aplicação do ferro e nos controles antes e após a aplicação. A aplicação do ferro agravou a condição clinica dos animais com doença respiratória, sendo evidenciada uma condição de toxidade refletida pelo estresse oxidativo. Assim sendo, não se deve recomendar tal suplementação nos caprinos acometidos de doenças do aparelho respiratório.

    Full Text Available El presente trabajo tiene por objeto revisar los aspectos teóricos y los estudios realizados en México que sugieren la existencia de la deficiencia moderada de zinc en niños de población rural, así como algunas de las consecuencias de dicha deficiencia en la salud. El zinc es un nutrimento indispensable para el organismo de los humanos y juega un papel importante en una serie de procesos metabólicos: participa en el sitio catalítico de varios sistemas enzimáticos; participa como ion estructural en membranas biológicas, y guarda una estrecha relación con la síntesis de proteínas, entre otras cosas. Es por esto que la deficiencia de zinc está asociada con consecuencias importantes en la salud y la funcionalidad de los individuos, especialmente durante las primeras etapas de la vida. De relevancia para México es la existencia de una deficiencia moderada de zinc en los niños y las consecuencias que ésta pueda tener en la salud de los mismos. Los estudios realizados sugieren que la deficiencia moderada de zinc se presenta asociada con la ingestión de dietas basadas en alimentos de origen vegetal, las cuales contienen cantidades importantes de inhibidores de la absorción de zinc. Este tipo de dietas se consume habitualmente en las zonas rurales y en la población marginal de las ciudades en el país. Entre las consecuencias más importantes de esta deficiencia se encontró un aumento en la presencia de enfermedades infecciosas, especialmente de diarrea, y posibles alteraciones en el desarrollo de la capacidad cognoscitiva.The purpose of this article is to review theoretical aspects and research performed in Mexico suggesting the existence of marginal zinc deficiency in rural children and its consequences on health.

    Full Text Available OBJETIVO: Avaliar fatores determinantes de anemia e deficiência de ferro em crianças de duas creches da cidade de Pontal, sudeste do Brasil. MÉTODOS: Estudo transversal foi realizado avaliando-se 192 crianças com idades entre 12 e 72 meses. Dados pessoais (idade, sexo, uso de ferro medicamentoso, duração do aleitamento materno, tipo de parto, cuidados pré-natais, peso e estatura e dados socioeconômicos (número de co-habitantes, escolaridade dos pais e renda per capita familiar foram obtidos e correlacionados com hemoglobina, receptores de transferrina, ferritina e anemia ferropriva. RESULTADOS: A idade foi a variável mais afetada pelo estado nutricional de ferro, correlacionando-se com maiores valores de hemoglobina e ferritina e menores valores de receptor de transferrina, sendo que menos anemia ferropriva foi detectada quanto maior a idade. As outras variáveis estudadas não apresentaram correlação com o estado nutricional de ferro. CONCLUSÃO: Os dados sugerem que as estratégias de controle para essa população de crianças pré-escolares devem ser direcionadas especialmente para aquelas de menor idade.OBJECTIVE: To examine the determining factors of anemia and iron deficiency in children attending two day care centers in the town of Pontal, southeast of Brazil.

    Full Text Available Cold agglutinin disease (CAD with autoimmune haemolytic anemia is characterized by the production of harmful cold autoantibodies associated with increased red cell destruction during exposure to cold. The treatment of CAD is very difficult and a great effort is required to obtain therapeutic success. Cyclophosphamide is a potent immunosuppressive agent which is widely used in all bone marrow transplantation conditioning regimens for patients with acquired severe aplastic anemia. In this report, we describe the case of a coronary artery disease patient with severe CAD, but without lymphoproliferative disease, in which general measures and immunosuppressive therapies were adopted, there by avoiding blood transfusions.A doença por aglutininas a frio (CAD cursando com anemia hemolítica auto-imune (AHAI é decorrente da produção de autoanticorpos que reagem muito bem a baixas temperaturas, dirigidos contra hemácias autólogas. A habilidade desses anticorpos em destruir as hemácias encontra-se diretamente relacionada à sua capacidade em fixar complemento durante a exposição do paciente a baixas temperaturas. A AHAI por anticorpos frios pode ser idiopática - ausência de doença de base - ou secundária, geralmente associada a desordens linfoproliferativas de células B ou determinados processos infecciosos. A hemólise é intravascular, através de aglutininas da classe IgM, com teste direto da antiglobulina humana positivo para complemento. O tratamento da CAD é difícil, exigindo um esforço contínuo, necessário para se obter sucesso terapêutico. A ciclofosfamida é um agente imunossupressor potente, amplamente utilizado em transplantes de medula óssea, particularmente nos portadores de anemia aplástica. Descrevemos o caso de um coronariopata portador de CAD severa, cuja exploração diagnóstica excluiu doença linfoproliferativa. Adotamos medidas gerais de suporte e terapia imunossupressora, coibindo o uso de hemotransfusões.

    Full Text Available Objective: To describe the occurrence of hospitalizations for iron deficiency anemia in Brazil between 2005 and 2014 by sex and age group. Methods: Observational epidemiological study, descriptive, retrospective with the qualitative and quantitative approach. The admission data were analyzed by place of detention for iron deficiency anemia in the regions of Brazil between 2005 and 2014 according to age group (0-19 years and sex, collected by the Department of Unified Health System through ICD-10 morbidity list. Results: The females had higher prevalence of hospitalizations with 52.03% of cases, however the male had the result of 47.97% incidence. The age group 15-19 was the most prevalent in women in all regions of Brazil. For men, the male children of hospitalizations of 1-4 years were the most frequent in all regions. Conclusion: The aged 15-19 years was the one with the highest number of hospitalizations among women, which may be explained by factors such as cycle menstrual, hormonal and behavioral changes related to the normal adolescence syndrome, beyond the Western lifestyle, that favors foods considered junk food. The age range of 1-4 years was the most prevalent in males. This can be explained by the increased need of mineral iron, for growth and development during the first 2 years of the child, the more accelerated in children.

    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

    Introducción: La anemia es una de las deficiencias nutricionales más importantes que afecta a varios estratos sociales y socioeconómicos. Es más frecuente en países en vías de desarrollo, estando los niños y los adolescentes en un riesgo significativamente mayor para padecer esta afección. Objetivo: Realizar una revisión bibliográfica sobre la anemia ferropénica en la adolescencia como un problema de salud pública y sobre los factores de riesgo que podrían contribuir en las deficiencias nutricionales, la detención del crecimiento y el desarrollo en este grupo de edad y poniendo el énfasis sobre la fisiopatología y las causas de la anemia, los diferentes abordajes diagnósticos y sus características clínicas, la prevención y el tratamiento. Metodología: Para este estudio, se consultaron las bases de datos LILACS-BIREME, SCIELO y PUBMED. Se seleccionaron los trabajos científicos publicados en español, portugués o inglés entre 2000 y 2013 sobre la anemia ferropénica. Se identificaron y evaluaron un total de 102 estudios publicados entre el 1º de enero de 2000 y el 30 de junio de 2013. Cuarenta y dos artículos que reunían los criterios de inclusión (adolescentes con anemia) se seleccionaron para esta revisión. Finalmente, se realizó un análisis y se evaluaron los artículos de acuerdo con los objetivos del estudio. Resultados y discusión: Los estudios revisados mostraron una prevalencia de anemia ferropénica cercana al 20 % en los adolescentes y describían los efectos deletéreos de la anemia en este grupo. Conclusión: Se requiere una acción preventiva con respecto a la anemia ferropénica. Los profesionales sanitarios deberían ser conscientes de la necesidad de un diagnóstico, profilaxis y tratamiento precoces.EL.

  10. Inborn anemias in mice

    International Nuclear Information System (INIS)

    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 α-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

Las concentraciones de ferritina sérica son constantemente monitoreadas en estos pacientes para detectar rápidamente la presencia de sobrecarga de hierro. El objetivo del estudio fue determinar si hubo correlación entre los valores de ferritina sérica y el número de unidades de transfusión de concentrado eritrocitario suministradas a los pacientes con ACS y βT mayor o intermedia durante un año. Se realizó un estudio prospectivo de 39 pacientes,22 fueron diagnosticados de ACS y 17 con βT, en edades comprendidas entre los 4 y 82 años. Estos pacientes fueron tratados en el "Instituto Hematológico de Occidente -Banco de Sangre del Estado Zulia y el Hospital Universitario de Maracaibo Venezuela”. Ferritina sérica se determinó por el método de quimioluminiscencia. La media y la desviación estándar de ferritina fueron 915,4 ± 567,8 ng/ml para los pacientes con ACS y 3.338 ± 874,6 para βT (p: 0.0001 Las unidades de concentrado eritrocitario transfundidas fueron 6 ± 2,3 y 21 ± 7,5 respectivamente (p: 0.0001.

    Full Text Available Se presenta el caso de un paciente masculino con neutropenia crónica e infección por el virus de inmunodeficiencia humana, con una revisión de los posibles mecanismos patogénicos. Las alteraciones hematológicas como anemia, trombocitopenia y leucopenia se presentan asociadas con frecuencia a la infección aguda por el virus de inmunodeficiencia humana. Al establecer la terapia antirretroviral y disminuir la actividad del virus, estas alteraciones tienden a mejorar. Sin embargo, algunos fármacos antirretrovirales, como la zidovudina, poseen toxicidad medular y pueden producir o empeorar las alteraciones hematológicas en estos pacientes, lo cual lleva a cambios en los esquemas de tratamiento. Los citotóxicos y antimetabolitos empleados en el tratamiento de neoplasias asociadas tienen conocida actividad depresora sobre la médula ósea. Algunos antimicrobianos utilizados en la profilaxis de infecciones poseen también toxicidad hematológica conocida, como el trimetoprim-sulfametoxazol, por lo que deben ser utilizados con precaución en pacientes con infección por el virus de inmunodeficiencia humana. Por otro lado, se plantean mecanismos alternativos que causan neutropenia en estos pacientes, como la formación de anticuerpos antineutrófilos, daño primario del progenitor granulocítico, por desbalance en la producción de neutrófilos, por anticuerpos contra la glicoproteína gp120 de la cápside viral del VIH, y deficiencias vitamínicas. En el caso del paciente neutropénico febril, en quien se sospecha infección bacteriana grave, se pueden utilizar los factores estimulantes de las colonias de granulocitos para aumentar los conteos absolutos de neutrófilos y mejorar la recuperación clínica.

    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.

    2016-06-01

    Anemia is a common problem in primary care. Classification based on mean cell volume narrows the differential diagnosis and directs testing. A marked macrocytosis is characteristic of vitamin B12 and folate deficiencies, certain medications, and primary bone marrow disorders. The three most common causes of microcytic anemia are iron deficiency, thalassemia trait, and anemia of inflammation. Additional laboratory testing is required for diagnosis. Determination of the rate of development of anemia and examination of a blood smear may provide diagnostic clues to guide more specialized testing. Diagnosis of iron, vitamin B12, or folate deficiency mandates determination of the underlying cause. PMID:27212091

    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.

Descripción: en ambos embarazos la madre realiza profilaxis de la enfermedad tromboembólica con heparina de bajo peso molecular para evitar la aparición de esta patología tanto en el embarazo como en el puerperio y mejorar el flujo útero-placen-tario. Con respecto a las complicaciones obstétricas, sólo existe un enlentecimiento del crecimiento fetal que obliga a un control obstétrico estricto. En ambas gestaciones los estudios eco-Doppler están dentro de la normalidad lo que permite una conducta expectante, consiguiendo llegar a término. Discusión: la profilaxis con heparina de bajo peso molecular en las gestantes con esta trombofilia y las intervenciones preventivas de factores de riesgo de enfermedad tromboembólica, junto con un control obstétrico adecuado, ha conseguido evitar la apari-ción de complicaciones derivadas de esta patología en el embarazo y en el puerperio.

  14. 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.

    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.

  7. Understanding anemia of chronic disease.

    Fraenkel, Paula G

    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.

  9. Perioperative intravenous iron: an upfront therapy for treating anaemia and reducing transfusion requirements Hierro intravenoso perioperatorio: una opción terapéutica para el tratamiento de la anemia y la reducción de los requerimientos de transfusión

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Perioperative anaemia, with iron deficiency being its leading cause, is a frequent condition among surgical patients, and has been linked to increased postoperative morbidity and mortality, and decreased quality of life. Postoperative anaemia is even more frequent and is mainly caused by perioperative blood loss, aggravated by inflammation-induced blunting of erythropoiesis. Allogenic transfusion is commonly used for treating acute perioperative anaemia, but it also increases the rate of morbidity and mortality in surgical and critically ill patients. Thus, overall concerns about adverse effects of both preoperative anaemia and allogeneic transfusion have prompted the review of transfusion practice and the search for safer and more biologically rational treatment options. In this paper, the role of intravenous iron therapy (mostly with iron sucrose and ferric carboxymaltose, as a safe and efficacious tool for treating anaemia and reducing transfusion requirements in surgical patients, as well as in other medical areas, has been reviewed. From the analysis of published data and despite the lack of high quality evidence in some areas, it seems fair to conclude that perioperative intravenous iron administration, with or without erythropoiesis stimulating agents, is safe, results in lower transfusion requirements and hastens recovery from postoperative anaemia. In addition, some studies have reported decreased rates of postoperative infection and mortality, and shorter length of hospital stay in surgical patients receiving intravenous iron.La anemia perioperatoria, cuya principal causa es la deficiencia de hierro, es frecuente entre pacientes quirúrgicos y se asocia a un aumento de la morbimortalidad postoperatoria y a una disminución de la calidad de vida.

    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.

  11. Iron Deficiency Anemia in Pregnancy.

    2015-10-01

    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.

    neurotransmisores y en la síntesis de ADN/ARN. Esta vitamina también puede ser un modulador de la expresión génica. Hoy en día, la deficiencia clínicamente evidente de vitamina B6 no es una afección habitual, al menos en la población general. Sin embargo, puede ocurrir una deficiencia subclínica no diagnosticada en algunos individuos, especialmente en los ancianos. Objetivo: esta revisión aporta una visión de conjunto completa sobre el metabolismo y las interacciones de la vitamina B6. Además, mostramos qué complicaciones y síntomas por deficiencia pueden ocurrir por la falta de vitamina B6 y las posibilidades de intervenciones de salud pública y de suplementos. Métodos: se buscó en la base de datos Medline (www.ncvi.nlm.nih.gov con los términos "vitamin B6", "pyridoxal", "cancer", "homocysteine", etc. Para una mayor comprensión, incluimos estudios con hallazgos iniciales de los años cuarenta, así como estudios recientes del año 2006. Se resumieron estos estudios y se compararon por capítulos diferentes. Resultados y Conclusión: de hecho, se ha propuesto que el estado sub-óptimo de vitamina B6 se asocia con ciertas enfermedades que afligen en especial a la población anciana: función cognitiva alterada, enfermedad de Alzheimer, cardiopatía y distintos tipos de cáncer. Algunos de estos problemas podrían relacionarse con concentraciones elevadas de homocisteína asociadas con una deficiencia de vitamina B6, pero también existe la evidencia de otros mecanismos independientes de la homocisteína por los que un estado sub-óptimo de vitamina B6 podría aumentar el riesgo de padecer estas enfermedades crónicas.

    Full Text Available Introducción: La vitamina D es esencial para la prevención de diversas enfermedades crónicas. Aunque se puede sintetizar a nivel cutáneo, esta fuente no es siempre suficiente para cubrir sus necesidades, por lo que el consumo de alimentos ricos en la misma, como el huevo, podría ser muy beneficioso en individuos que están en riesgo de presentar deficiencia. Objetivo: Estudiar la relación entre el estatus en vitamina D y el consumo diario de huevos en un colectivo de escolares. Metodología: Se incluyeron 564 escolares (9 a 12 años de la Comunidad de Madrid. La ingesta de alimentos, de energía y nutrientes (incluidos el huevo y la vitamina D, se determinó empleando un registro del consumo de alimentos durante 3 días. Se calculó el Índice de Masa Corporal a través del peso corporal y la talla. Se valoró el colesterol total, lipoproteínas, triglicéridos y vitamina D sérica. Resultados: El consumo medio de huevos fue de 32,7 ± 20,9 g/día (inferior a 0,5 huevo/día recomendados en el 36,3% de los escolares. Se dividió a los escolares en función de que tuvieran un consumo > o < 0,5 huevo/día (grupos SH e IH, respectivamente. La ingesta y los niveles séricos de vitamina D fueron significativamente superiores en el grupo SH que en el IH. Además, los primeros tuvieron menor riesgo de presentar deficiencia moderada de vitamina D (< 50 nmol/L (OR = 0,41 (0,19-0,88; p = 0,022. No se observaron diferencias significativas entre los grupos en relación con las cifras de colesterol total y triglicéridos. Conclusión: Es recomendable fomentar el consumo de al menos 0,5 huevo/día entre la población infantil debido a su alto contenido en vitamina D, lo que podría evitar la aparición de problemas de salud.

    Full Text Available A anemia falciforme tem um desenvolvimento clínico extremamente variável que se caracteriza principalmente por diferentes graus de intensidade da anemia hemolítica. As razões dessa variabilidade são parcialmente conhecidas na expressão fenotípica da doença. Apesar de ter um mesmo defeito genético, a anemia falciforme pode estar associada com níveis diferentes de Hb Fetal e interações com talassemia alfa que atuam como modeladores genéticos da doença. Entretanto, outros defeitos genéticos dos eritrócitos, com destaques para a deficiência de G-6PD, a esferocitose e as deficiências de enzimas anti-oxidantes (SOD, GPx e catalase certamente interferem no curso clínico da doença. Os diferentes haplótipos da Hb S denominados por Banto, Benin, Senegal, Camarões e Asiático, tem sido apontados também como possíveis causas da heterogeneidade fenotípica da anemia falciforme. Toda essa diversidade que caracteriza a anemia falciforme está, em parte, relacionada à sua origem multicêntrica e que envolvem populações com diferentes anormalidades genéticas de proteínas e enzimas eritrocitárias. Por outro lado, além desses fatores caracterizados como interferentes eritrocitários, há os interferentes do meio ambiente em que está inserido o doente com anemia falciforme. Entre os interferentes ambientais destacam-se as situações sociais, econômicas e culturais do doente, e que tem influência no curso de sua doença. Diante desse quadro complexo e interativo, o presente artigo mostra a influência de certos interferentes eritrocitários e ambientais na anemia falciforme. Ao finalizar o artigo é proposto um protocolo de monitoramento laboratorial das síndromes falcêmicas, com destaque para a anemia falciforme.

    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

  6. 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.

    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.

    Lower hemoglobin is associated with cognitive impairment and Alzheimer's disease (AD). Since brain iron homeostasis is perturbed in AD, we investigated whether this is peripherally reflected in the hematological and related blood chemistry values from the Australian Imaging Biomarker and Lifestyle (AIBL) study (a community-based, cross-sectional cohort comprising 768 healthy controls (HC), 133 participants with mild cognitive impairment (MCI) and 211 participants with AD). We found that individuals with AD had significantly lower hemoglobin, mean cell hemoglobin concentrations, packed cell volume and higher erythrocyte sedimentation rates (adjusted for age, gender, APOE-ɛ4 and site). In AD, plasma iron, transferrin, transferrin saturation and red cell folate levels exhibited a significant distortion of their customary relationship to hemoglobin levels. There was a strong association between anemia and AD (adjusted odds ratio (OR)=2.43, confidence interval (CI) (1.31, 4.54)). Moreover, AD emerged as a strong risk factor for anemia on step-down regression, even when controlling for all other available explanations for anemia (adjusted OR=3.41, 95% CI (1.68, 6.92)). These data indicated that AD is complicated by anemia, which may itself contribute to cognitive decline. PMID:24419041

    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.

    Hemolytic anemias consist of corpuscular, immun-hemolytic and toxic hemolytic anemias. Within the group of corpuscular hemolytic anemias, except for the paroxysmal nocturnal hemoglobinuria (PNH), all symptoms are caused by underlying heredetiary disorders within the red blood cell membran (hereditary spherocytosis), deficiencies of red cell enzymes (G6PDH- and pyrovatkinase deficiency) or disorders in the hemoglobin molecule (thalassaemia and sickle cell disease). Immune-hemolytic anemias are acquired hemolytic anemias and hemolysis is caused by auto- or allo-antibodies which are directed against red blood cell antigens. They are classified as warm, cold, mixed type or drug-induced hemolytic anemia. Therapy consists of glucocorticoids and other immunsuppressive drugs. Pernicious anemia is the most important vitamin B12 deficiency disorder. Diagnosis relies on cobalamin deficiency and antibodies to intrinsic factor. The management should focus on a possibly life-long replacement treatment with cobalamin. PMID:26306021

    Full Text Available Se presenta el caso de un paciente masculino con neutropenia crónica e infección por el virus de inmunodeficiencia humana, con una revisión de los posibles mecanismos patogénicos. Las alteraciones hematológicas como anemia, trombocitopenia y leucopenia se presentan asociadas con frecuencia a la infección aguda por el virus de inmunodeficiencia humana. Al establecer la terapia antirretroviral y disminuir la actividad del virus, estas alteraciones tienden a mejorar. Sin embargo, algunos fármacos antirretrovirales, como la zidovudina, poseen toxicidad medular y pueden producir o empeorar las alteraciones hematológicas en estos pacientes, lo cual lleva a cambios en los esquemas de tratamiento. Los citotóxicos y antimetabolitos empleados en el tratamiento de neoplasias asociadas tienen conocida actividad depresora sobre la médula ósea. Algunos antimicrobianos utilizados en la profilaxis de infecciones poseen también toxicidad hematológica conocida, como el trimetoprim-sulfametoxazol, por lo que deben ser utilizados con precaución en pacientes con infección por el virus de inmunodeficiencia humana. Por otro lado, se plantean mecanismos alternativos que causan neutropenia en estos pacientes, como la formación de anticuerpos antineutrófilos, daño primario del progenitor granulocítico, por desbalance en la producción de neutrófilos, por anticuerpos contra la glicoproteína gp120 de la cápside viral del VIH, y deficiencias vitamínicas.

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.

    2007-11-01

    An increasing understanding of the process of erythropoiesis raises some interesting questions about the pathophysiology, diagnosis and treatment of anemia and erythrocytosis. The mechanisms underlying the development of many of the erythrocytoses, previously characterised as idiopathic, have been elucidated leading to an increased understanding of oxygen homeostasis. Characterisation of anemia and erythrocytosis in relation to serum erythropoietin levels can be a useful addition to clinical diagnostic criteria and provide a rationale for treatment with erythropoiesis stimulating agents (ESAs). Recombinant human erythropoietin as well as other ESAs are now widely used to treat anemias associated with a range of conditions, including chronic kidney disease, chronic inflammatory disorders and cancer. There is also heightened awareness of the potential abuse of ESAs to boost athletic performance in competitive sport. The discovery of erythropoietin receptors outside of the erythropoietic compartment may herald future applications for ESAs in the management of neurological and cardiac diseases. The current controversy concerning optimal hemoglobin levels in chronic kidney disease patients treated with ESAs and the potential negative clinical outcomes of ESA treatment in cancer reinforces the need for cautious evaluation of the pleiotropic effects of ESAs in non-erythroid tissues.

    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.

O diagnóstico diferencial das referidas anemias é de grande importância clínica; contudo, muitas vezes é complexo em virtude de concomitância de doenças, além de demandar tempo e apresentar custos significativos. Com o propósito de conferir maior simplicidade e eficiência ao diagnóstico diferencial destas anemias, o uso de índices derivados de modernos contadores automáticos tem sido sugerido. Entre estes, pode ser citado o índice de anisocitose eritrocitária (RDW, que indica o grau de variabilidade do tamanho das hemácias. Neste estudo, o poder de discriminação deste índice quanto ao tipo de anemia microcítica e hipocrômica foi avaliado em um grupo de 159 pacientes sabidamente portadores de um quadro de anemia causado por deficiência de ferro, beta talassemia menor ou uma anemia de doença crônica. Não foi observada diferença significativa para o RDW entre os três grupos de anemias microcíticas, indicando não ser este índice uma ferramenta útil para a diferenciação entre anemia ferropriva, beta talassemia menor e anemia de doença crônica.Iron deficiency anemia, the thalassemia trait and chronic disease anemia are the most common microcytic and hypochromic anemias in the Brazilian population.

In order to simplify and increase efficiently of checking the differential diagnoses of these anemias, the use of indexes derived from modern blood cell counters has been suggested. Among them, is the index called red blood cell distribution width which indicates the variability in red blood cell size.

    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.

Ao reunir esses informes, constata-se que a anemia continua, desde a antiguidade, a ser uma das entidades nosológicas mais prevalentes e difundidas nas populações humanas. A partir daí surge uma série de questionamentos ainda sem respostas em relação às reais prevalência e etiopatogenia do problema, ao grau de implantação e à efetividade das medidas de controle.In 1990, the United Nations held a World Summit in New York, in which goals for the upcoming decade were established. One of these goals was a one-third reduction in the prevalence of anemia among women at childbearing age. Despite this modest percentage, epidemiological indicators point to the opposite direction, indicating an increasing occurrence of anemia in different regions of the world, including in Brazil. These data show that anemia has continued since the antiquity to be one of the most prevalent and widespread diseases in human populations. Thus, a number of questions without answers arise regarding the actual prevalence and etiopathogenesis of the problem as well as with respect to the degree of implantation and the effectiveness of control measures.

    longerterm selenium status, while plasma selenium appears to be a marker of short-term nutritional status. The present findings indicate a positive correlation between plasma selenium concentration and the practice of physical activity. Bioavailability studies are required to establish appropriate reference levels of this mineral for the Spanish population.Introducción: El selenio es un micronutriente esencial para la salud del ser humano, debido fundamentalmente a su implicación como cofactor de enzimas con actividad antioxidante que protegen al organismo del daño oxidativo, de modo que una ingesta inadecuada de este mineral está asociada con la aparición y desarrollo de enfermedades crónicas tales como hipertensión, diabetes, enfermedades coronarias, asma y cáncer. Por esta razón, la determinación de selenio plasmático y eritrocitario contribuirá a la valoración del estado nutricional de la población estudiada. Objetivo: El objetivo de estudio fue valorar el estado nutricional de selenio en una población adulta sana en riesgo de deficiencia, a través de una evaluación de la ingesta, así como de los niveles de selenio en plasma y eritrocito, y la actividad de la enzima selenio-dependiente Glutation Peroxidasa (GPx en eritrocito. Material y métodos: El estudio se realizó en un grupo de población de 84 adultos sanos pertenecientes a la provincia de Granada (31 hombres y 53 mujeres en los que se determinó la ingesta de nutrientes y selenio, sus niveles plasmáticos y eritrocitarios, así como su asociación con la actividad de la enzima Glutation Peroxidasa y con diversos factores del estilo de vida.

    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. PMID:26818422

    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. .

    2015-07-01

    Anemia is a common problem in the neonatal period. Presenting symptoms may suggest numerous possible diagnoses ranging from anemia seen as a normal part of development to anemia due to critical pathology. An illustrative case is presented to highlight the appropriate evaluation of the neonate with significant anemia. Several important features of the evaluation of neonatal anemia are highlighted. The constellation of signs and symptoms that occur in conjunction with the anemia are critical for the evaluation. The evaluation should be performed in a step-wise process that starts by eliminating common causes of anemia. Manual review of the peripheral blood smear with a hematologist can be helpful.

    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

    Anemia and thrombocytopenia are frequent clinical manifestations of myelofibrosis as well as important prognostic factors of the disease. Concerning the treatment of anemia, the first step should be the correction of reversible contributing factors, such as possible iron, folate and vitamin B12 deficiency. Then, treatment options include erythropoiesis stimulating agents, androgens, immunomodulating drugs, corticosteroids, and splenectomy. Anemia responses may also be observed in some patients treated with JAK inhibitors. However, most patients eventually fail to such therapies and become transfusion dependent. Some of the aforementioned therapies can also improve thrombocytopenia, but the responses are usually observed in patients with moderate platelet count decrease. Allogeneic hematopoietic stem cell transplantation, the only curative treatment of myelofibrosis, can be an alternative for selected patients with cytopenias who are refractory to conventional therapies. However, for the majority of patients, the management of anemia and severe thrombocytopenia remains an unmet need. PMID:26891375

    Following acute arsenic ingestion, a 35 year old woman experienced multiple organ failure, including renal and respiratory insufficiency, toxic hepatitis, peripheral neuropathy, and encephalopathy. In addition, she developed an anemia; the bone marrow showed a striking dyserythropoiesis with megaloblastic features. Her recovery was heralded by normalization of the bone marrow morphology, followed by improvement in all other organ dysfunction except for the peripheral neuropathy. Arsenic poisoning is a cause of megaloblastic anemia; early hematologic recovery suggests favorable prognosis.

    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.

    Freeman, Hugh James

    2015-08-21

    Iron is an important micronutrient that may be depleted in celiac disease. Iron deficiency and anemia may complicate well-established celiac disease, but may also be the presenting clinical feature in the absence of diarrhea or weight loss. If iron deficiency anemia occurs, it should be thoroughly evaluated, even if celiac disease has been defined since other superimposed causes of iron deficiency anemia may be present. Most often, impaired duodenal mucosal uptake of iron is evident since surface absorptive area in the duodenum is reduced, in large part, because celiac disease is an immune-mediated disorder largely focused in the proximal small intestinal mucosa. Some studies have also suggested that blood loss may occur in celiac disease, sometimes from superimposed small intestinal disorders, including ulceration or neoplastic diseases, particularly lymphoma. In addition, other associated gastric or colonic disorders may be responsible for blood loss. Rarely, an immune-mediated hemolytic disorder with increased urine iron loss may occur that may respond to a gluten-free diet. Reduced expression of different regulatory proteins critical in iron uptake has also been defined in the presence and absence of anemia. Finally, other rare causes of microcytic anemia may occur in celiac disease, including a sideroblastic form of anemia reported to have responded to a gluten-free diet.

    Utilizing longitudinal data from the nationally-representative Mexico Family Life Survey, this study assesses the association between family structure and iron-deficient anemia among children ages 3-12 in Mexico. The longitudinal models (n = 4649), which control for baseline anemia status and allow for consideration of family structure transitions, suggest that children living in stable-cohabiting and single-mother families and those who have recently experienced a parental union dissolution have higher odds of anemia than those in stable-married, father-present family structures. Interaction effects indicate that unmarried family contexts have stronger associations with anemia in older children (over age five); and, that the negative effects of parental union dissolution are exacerbated in poorer households. Resident maternal grandparents have a significant beneficial effect on child anemia independent of parental family structure. These results highlight the importance of family structure for child micronutrient deficiencies and suggest that understanding social processes within households may be critical to preventing child anemia in Mexico.

    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.

    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.

    Full Text Available Increased cardiovascular morbidity and mortality has been reported in adult subjects with growth hormone deficiency (GHD. Long term follow up of a large cohort of patients with adult onset GHD, suggests that GH therapy may contribute to a reduced risk of nonfatal stroke, particularly in women and in a decline in nonfatal cardiac events in GHD men(1,2. Adult hypopituitary patients with untreated growth hormone deficiency have been shown to have a cluster of cardiovascular risk factors such as increased visceral adiposity, disturbances in lipoprotein metabolism, premature atherosclerosis, impaired fibrinolytic activity, increased peripheral insulin resistance, abnormal cardiac structure, impaired cardiac performance and endothelial dysfunction (3,4. Several of these risk factors have now been confirmed in double blind, randomized, placebo controlled trials (5,6. Metabolic changes in GH deficient children and adolescents have been evaluated only quite recently and superficially. In this article we will discuss these metabolic abnormalities and their underlying mechanism in untreated GHD subjects and we will review the beneficial effect of growth hormone therapy in adults, adolescents and children with GHD.Se ha reportado un aumento en la morbilidad y mortalidad de pacientes adultos con deficiencia de la hormona de crecimiento (DHC.

  3. Correlative study on anemia and radiotherapy effects in nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Objective: To study the effect of oxygen-carrying ability of blood efficacy of radiotherapy for patients with nasopharyngeal carcinoma. Methods: Altogether 161 cases of patients with nasopharyngeal carcinoma were classified according to severity of anemia, and Hb, RBC, MCH, HCT, MCV, MCHC and RDW were tested before, during and after radiotherapy. The patients were followed-up for up to 5 years, the relationship and mechanism among anemia, radiotherapy effects and survival rate was discussed. Results: The survival rate between anemia group and non-anemia group was different significantly (P<0.05). Anemia before radiotherapy, anemia appearance or anemia deterioration during radiotherapy were sensitive factors affecting radiotherapy results. The anemia more severe, the radiotherapy worse. Conclusion: Anemia-hypohemoglobinemia leads to decrease of oxygen-carrying capacity of blood, resulting in oxygen deficiency of tumor cells and their radiotherapy resistance. Therefore this method is worthy of further studies

    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.

    Full Text Available OBJETIVO: Revisar aspectos do consumo de leite de vaca associados à anemia na infância. FONTES DOS DADOS: As informações foram coletadas a partir de artigos publicados nas 2 últimas décadas, pesquisados nas bases de dados Lilacs e MEDLINE, livros técnicos e publicações de organizações internacionais. SÍNTESE DOS DADOS: A anemia ferropriva é um grave problema de saúde pública nos países em desenvolvimento. Até os 6 meses de idade, o leite materno supre as necessidades de ferro das crianças nascidas a termo. A partir daí, torna-se necessária a ingestão de uma alimentação complementar rica em ferro. Considerando a importância da dieta na determinação da anemia e o alto consumo de leite de vaca na infância, discute-se neste artigo a relação desse alimento com a deficiência de ferro. A introdução precoce ou a substituição do leite materno por leite de vaca pode ocasionar problemas gastrintestinais e alérgicos. Além disso, esse alimento apresenta baixa biodisponibilidade e densidade de ferro, excesso de proteínas e minerais, especialmente cálcio, interferindo na absorção do ferro de outros alimentos, e associa-se às micro-hemorragias intestinais, principalmente nas crianças menores. CONCLUSÕES: A utilização do leite de vaca em detrimento de outros alimentos ricos em ferro biodisponível constitui um risco para o desenvolvimento da anemia. O estímulo ao aleitamento materno exclusivo até os 6 meses de vida e sua continuidade até pelo menos 24 meses, juntamente com uma dieta complementar rica em ferro são medidas de grande importância para a prevenção da anemia e de suas conseqüências na infância.OBJECTIVE: To thoroughly investigate the association between the consumption of cow's milk and anemia in childhood.

    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.

O delineamento foi transversal, com amostra aleatória sistemática de 284 idosos > 60 anos, de ambos os sexos, realizado em novembro/dezembro-2003. A anemia foi avaliada pela hemoglobina (Hb, concentração de hemoglobina corpuscular média (CHCM, volume corpuscular médio (VCM e amplitude de distribuição eritrocitária (RDW. A prevalência de anemia foi, em média, de 11,0%. A morfologia eritrocitária não mostrou associação com as concentrações de Hb. A grande maioria dos idosos apresentou anemia normocrômica, normocítica, sem anisocitose, sugestivo de anemia por doença crônica. A ínfima prevalência de microcitose e macrocitose com anisocitoseminimiza a gênese da deficiência de ferro, bem como da deficiência de vitamina B12 e ácido fólico na etiologia da anemia em idosos. Concluímos que o uso de indicadores que reflitam o grau de anisocitose eritrocitária associados àqueles que avaliam o estado nutricional do ferro é extremamente recomendado para o diagnóstico das anemias em idosos.Anemia is a serious public health problem worldwide that mainly affects children and women of childbearing age.

    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

No Brasil, é uma das doenças genética e hereditária mais prevalente e que ocorre, principalmente, nos afrodescendentes, devido à herança genética africana, por se tratar de uma doença originária na África. Materiais e Métodos: Pesquisa exploratória descritiva com abordagem qualitativa, realizada num município a 197 km de Salvador, Bahia, Brasil, capital do Estado. Participaram do estudo dez pessoas, das quais cinco eram pacientes com doença falciforme e cinco familiares. A coleta de dados ocorreu nos meses de julho e agosto de 2012, com a realização de entrevista semiestruturada com o uso de gravador. A análise dos dados se deu a parti da Técnica de Análise de Conteúdo proposta por Bardin. Resultados: Da análise emergiram quatro categorias, a saber: sentimentos relacionados à condição crônica da doença; relações sociais; vivendo com a anemia falciforme e suas limitações; conhecimento dos familiares sobre anemia falciforme. Discussão e Conclusões: Os portadores demonstraram a presença de obstáculos de natureza psicossocial, que somados com a condição crônica da doença, alteram sua qualidade de vida. Além de que, evidenciouse que os fatores sociais e econômicos interferem na sua qualidade de vida, sendo o desemprego um dos fatores mais impactante, contribuindo negativamente para a insatisfação em relação a sua qualidade de vida.

    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.

    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.

    The aim of this study was to establish the prevalence of anemia in stable pediatric renal transplant recipients and to examine the association of anemia with renal function, immunosuppressants, angiotensin converting enzyme inhibitors, and growth, as well as iron, vitamin B(12), and folate stores. This is a cross-sectional study of the 50 renal transplant recipients currently followed at our center. Patient data were collected regarding hematological parameters, growth, medications, renal function, underlying renal disease, delayed graft function, episodes of rejection, and iron or erythropoietin therapy post transplantation. The mean hemoglobin level (Hb) was 110 g/l and the overall prevalence of anemia was 60%, including 30% who were severely anemic (Hb<100 g/l). There was a high rate of iron deficiency (34%) and serum iron was the parameter of iron metabolism most closely associated with anemia. Hb in patients with low serum iron was 90.7 g/l versus 114.4 g/l in those with normal serum iron ( P<0.01). Both univariate and multiple linear regression determined tacrolimus dose and creatinine clearance to be significant factors associated with anemia. Tacrolimus dose correlated with a 10 g/l reduction in Hb for every increase of tacrolimus dose of 0.054 mg/kg per day ( P=0.001). The dose of mycophenolate was positively correlated with Hb, but this was likely to be confounded by our practice of dose reduction in the setting of anemia. Angiotensin converting enzyme inhibitor use was not associated with anemia. Severely anemic patients tended to be shorter, with a mean Z-score for height of -1.8 compared with -0.9 for those with normal Hb ( P=0.02). Anemia is a significant and common problem in pediatric renal transplant patients. Deteriorating renal function is an important cause, but other factors like iron deficiency and immunosuppression are involved. Definition of iron deficiency is difficult and serum iron may be a valuable indicator. Medication doses

    Megaloblastic anemia (MA) is a common disorder with varied manifestations. It generally results in mild to moderate splenomegaly which is due to sequestration of macrocytic erythrocytes in spleen. Massive splenomegaly is generally seen in infections, myeloproliferative diseases, neoplasms, storage disorders or hematological conditions; but is not heard of and has rarely been reported in MA. We discuss a case of massive splenomegaly who presented with symptomatic anemia and was found to have MA. He was extensive evaluated for all other causes of massive splenomegaly which was normal. Further, after a therapeutic trial of MA he showed a regression in spleen size confirming that the massive splenomegaly was attributable to MA. PMID:25825577

    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. PMID:26862056

    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.

    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. PMID:27542426

  3. Fanconi anemia proteins in telomere maintenance.

    Sarkar, Jaya; Liu, Yie

    2016-07-01

    Mammalian chromosome ends are protected by nucleoprotein structures called telomeres. Telomeres ensure genome stability by preventing chromosome termini from being recognized as DNA damage. Telomere length homeostasis is inevitable for telomere maintenance because critical shortening or over-lengthening of telomeres may lead to DNA damage response or delay in DNA replication, and hence genome instability. Due to their repetitive DNA sequence, unique architecture, bound shelterin proteins, and high propensity to form alternate/secondary DNA structures, telomeres are like common fragile sites and pose an inherent challenge to the progression of DNA replication, repair, and recombination apparatus. It is conceivable that longer the telomeres are, greater is the severity of such challenges. Recent studies have linked excessively long telomeres with increased tumorigenesis. Here we discuss telomere abnormalities in a rare recessive chromosomal instability disorder called Fanconi Anemia and the role of the Fanconi Anemia pathway in telomere biology. Reports suggest that Fanconi Anemia proteins play a role in maintaining long telomeres, including processing telomeric joint molecule intermediates. We speculate that ablation of the Fanconi Anemia pathway would lead to inadequate aberrant structural barrier resolution at excessively long telomeres, thereby causing replicative burden on the cell.

    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.

    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.

    Full Text Available A deformabilidade é a característica que permite ao eritrócito normal de 7 a 8 micrômetros (µm circular por capilares de até 3 µm de diâmetro. Esse fenômeno depende da geometria celular, da viscosidade interna e de propriedades visco-elásticas da membrana eritrocitária. Dentre as técnicas de estudo da deformabilidade eritrocitária (DE, como aspiração por micropipeta, filtração e reoscopia, destaca-se a ectacitometria. Esta técnica utiliza um viscosímetro de fluxo laminar no qual as modificações de forma dos eritrócitos são monitoradas continuamente por um feixe de raio laser, processadas por microcomputador, gerando o "Índice de Deformabilidade" (ID, que mede a eliptocitogênese dos eritrócitos quando submetidos a uma força denominada "shear stressl". Alterações de DE foram descritas em diversas situações, como em anemias hemolíticas hereditárias ou auto-imunes. Na anemia ferropriva, os trabalhos são controversos. O presente estudo avalia a DE em 21 pacientes portadores de anemia ferropriva, utilizando a ectacitometria. Os resultados obtidos a partir do ID demonstram DE diminuída nesses doentes, quando comparada ao grupo controle (pDeformability allows the 7 to 8 µm red cell to cirDeformability allows the 7- to 8-µm red blood cells to circulate through capillaries of 3 µm. This phenomenon depends on cellular geometry, internal viscosity and viscoelastic properties of the membrane. Among the various techniques of erythrocyte deformability analysis, such as micropipette aspiration, filtration and reoscopy, we chose ektacytometry. This technique uses a laminar flow viscometry, where red blood cell shape changes are continuously monitored by laser, processed by a computer, generating the "Deformability Index", which shows the elliptocytogenesis of the erythrocyte under "shear stressl" force. Erythrocyte deformability has been described in a number of situations like hereditary or autoimmune hemolytic anemia. In

    Full Text Available RACIONAL: As anemias ferropriva, perniciosa e megaloblástica são comuns após procedimentos bariátricos como o bypass e as derivações biliopancreáticas. As principais causas devem-se ao desvio duodenal e do jejuno proximal do trânsito alimentar e, em menor grau, às úlceras anastomóticas. Entretanto a dieta pobre em nutrientes, a suplementação vitamínica inadequada, medicamentos, uso de álcool e neoplasias devem ser lembrados. RELATO DOS CASOS: Os autores relatam dois casos de pacientes pós-procedimentos bariátricos com anemia severa sem controle clínico e cuja investigação identificou melanoma metastático em um caso e neoplasia colônica no segundo, ambos tratados cirurgicamente com bons resultados. CONCLUSÃO: Anemias são comuns após procedimentos bariátricos, porém causas atípicas como neoplasias devem ser suspeitadas nos pacientes mais idosos e principalmente naqueles refratários ao controle clínico.BACKGROUND: Iron deficiency anemia, pernicious and megaloblastic are common after gastric bypass and biliopancreatic diversion. The main causes are due to duodenal exclusion and anastomotic ulcers. However, low protein diet, vitaminic supplementation, medicines, alcohol and tumors must be remembered. CASES REPORT: The authors relate two cases of severe anemia after bariatric procedures that were diagnosed as metastatic melanoma in small bowel and a colorectal cancer treated surgically with good results. CONCLUSION: Anemias are common after bariatric surgery, however unusual causes like tumors must be suspected in the elderly and in those patients that clinical treatment didn't have good results.

    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.

    Full Text Available Anemia during childhood impairs physical growth, cognitive development and school performance. Identifying the causes of anemia in specific contexts can help efforts to prevent negative consequences of anemia among children. The objective of this study was to assess prevalence and identify correlates of anemia among school children in Eastern Ethiopia.A cross sectional study was conducted from January 2012 to February 2012 in Kersa, Eastern Ethiopia. The study included randomly selected primary school students. Hemoglobin concentration was measured using a Hemocue haemoglobinometer. A child was identified as anemic if the hemoglobin concentration was <11.5 g/dl for children (5-11 yrs and < 12 g/dl for child older than 12 years age. Poisson regression model with robust variance was used to calculate prevalence ratios.The overall prevalence of anemia was 27.1% (95% CI: 24.98, 29.14: 13.8% had mild, 10.8% moderate, and 2.3% severe anemia. Children with in the age group of 5-9 years (APR, 1.083; 95% CI, 1.044-1.124 were at higher risk for anemia. Paternal education (Illiterate, 1.109; 1.044-1.178 was positively associated with anemia. Children who had irregular legume consumption (APR, 1.069; 95% CI, 1.022-1.118 were at higher risk for anemia.About a quarter of school children suffer from anemia and their educational potential is likely to be affected especially for those with moderate and severe anemia. Child age, irregular legume consumption, and low paternal schooling were associated with anemia. Intervention programmes aimed to reduce anemia among school children are crucial to ensure proper growth and development of children.

  17. 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.

    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.

    Many validated instruments exist for determining the impact of chemotherapy-induced anemia and related fatigue on patient quality of life, but few studies analyze how healthcare providers actually discuss these subjects with patients. The authors share their study results on patterns of communication between participating patients and their physicians and allied health professionals. Letters of invitation were mailed to over 1,000 community-based oncologists, 15 of whom met the criteria and agreed to participate in this study on a first-enrolled basis until sufficient participation was ensured. In total, 36 of their patients were audio- and/or video-recorded during their regularly scheduled visits. Post-visit interviews were conducted separately with patients and participating healthcare professionals. Interviews were transcribed and analyzed using sociolinguistic techniques. Although 52% of visit time was spent discussing side effects and symptoms, most discussions of anemia and fatigue lacked specificity necessary to determine their true impact on patients' lives. Physician inquiries regarding fatigue also tended to be too brief to elicit patients' chief concerns. Vocabulary used to discuss anemia and related fatigue was variable and imprecise, and no fatigue assessment instrument was used or referenced in any visit. Community-based oncologists are encouraged to modify their vocabulary and consider incorporating a validated fatigue instrument, either within or before the consultation, to improve the quality of such communication.

    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 is highly prevalent among chronic kidney disease (CKD) patients and patients receiving renal replacement therapy. In this paper we will outline the prevention and treatment of anemia in patients treated with peritoneal dialysis (PD). PD patients are less anemic and more sensitive to erythropoesis-stimulating agent (ESA) than their hemodialysis (HD) counterparts and, in general, dosages required for achieving similar hemoglobin levels to those achieved in HD patients are remarkably less. Before starting with ESA treatment we have to evaluate the degree of anemia and excluded other causes which are not connected with CKD and method of treatment. Patient's compliance is crucial for a successful therapy and it can be improved by decreasing frequency of administration of ESA. Since ESAare expensive, "cost-effectivnes" studies represent an important factor in choosing a distinct drug. Subcutaneous administration provides better long-term utilization of ESA in comparison to intravenous administration and is therefore preferred in PD patients. Intraperitoneal administration is not recommended due to poor bioavailability. In some patients we can observe the reduced response to ESA therapy. The definition of reduced response is generally regarded as a failure to achieve target hemoglobin concentration of >11 g/dL. Identification of underlying cause is not always easy but every attempt should be made to investigate every patient with resistance to therapy because some causes are easily corrected. Since 2005 particular ESA drugs have been approved by Croatian Institute for Health Insurance and registered for use in Croatia. For PD patients the ESAcan be prescribed by general practitioner. The list of available drugs is available in the official government newspaper Nardone novine No.27, March 2nd, 2009. PMID:20232548

  1. Iron, anemia and hepcidin in malaria

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available Objective: To determine the prevalence of anemia and nutritional anemia in primary school children in the city of Aydın. Materials and Methods: In Aydın, the central town of Aydın province, a total of 496 students (56% were female were enrolled into the study by using stratified random sampling method. The students were from the primary schools located in socio-economically low, medium, and high areas of primary health care centers. The avarage age of the students was 10.2±2 years. Statistical analysis was performed using the Kolmogorov-Smirnov test, Student’s t-test, Mann-Whitney U-test and Chi-Square test. Results: The prevalence of anemia, iron-deficiency (ID, iron-deficiency anemia (IDA, vitamin B12 deficiency and vitamin B12 deficiency anemia was 15.7%, 38.7%, 8.3%, 9.1%, 0.8%, respectively. No folic acid deficiency was detected. Among the anemias, 42% of them were microcytic, 58% of them were normocytic and the 45.5% of the microcytic anemias were IDA. Among the females, the rate of ID was 45.1% and the rate of IDA was 11.6%, while in boys the same rates were 30.6% and 4.1%, respectively (p<0.05. Microcytosis was present in 36.5% of subjects with IDA. The Mentzer index was <13 in 13.3% of subjects with microcytic anemia and IDA, and in 77.7% of children with microcytic anemia and no IDA (p<0.001. Regarding socio-demographic characteristics of children; the only statistically significant difference was in the parameters of mother education and anemia. Conclusion: The prevalence of anemia represents a minor public health problem according to the World Health Organization criteria among the primary school students in the central town of Aydın province. Exploration of the reason of anemia among pre-school children, proper treatment of nutritional anemia cases with adequate duration and dose, dietary organizations and proper follow-up will lower the incidence of anemia and nutritional anemia among primary school children.

El diagnóstico se estableció a partir de un cuadro de astenia progresiva con una importante pérdida de peso. La analítica mostró anemia ferropénica y eosinofilia, por lo que fue ingresado para estudio hospitalario por Medicina interna, encontrándose huevos de uncinarias en heces. Se realizó tratamiento con Albendazol y hierro consiguiéndose la curación clínica,la normalización de los parámetros bioquímicos y la negativización de las muestras de heces. Creemos que es necesario por parte del médico de prisiones pensar en esta y otras parasitosis ante internos procedentes de países tropicales, donde estas helmintosis son endémicas.

    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.

    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.

    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.

    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.

    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

    Hookworm infections as well as other intestinal nematodiases are endemic in China. In this case, a 70-year-old male showed symptoms of chest tightness, shortness of breath, and both lower extremities edema. The diagnostic result was chronic renal insufficiency, chronic kidney disease (5th stage), and renal anemia at first. Then, he received treatment with traditional drugs. However, this treatment did not help to alleviate the symptoms of the patient significantly. The results of gastroendoscopy showed hookworms in the duodenum, also confirmed by pathology examination. Anemia was markedly ameliorated after eliminating the parasites. The results mentioned above suggested that ancylostomiasis was the leading causes of anemia in this patient, and the etiology of anemia in uremic patients should be systematically considered. Especially when anemia could not be cured by regular treatments, rare diseases should be investigated. PMID:27417086

    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.

  7. Microfluidic approach of Sickled Cell Anemia

    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.

    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.

    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.

    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.

    Pernicious anemia (also known as Biermer disease or anemia, Addison or Addisonian anemia, and Addison-Biermer anemia) is an autoimmune atrophic gastritis responsible for vitamin B12 malabsorption due to a deficiency of intrinsic factor. We report eight cases of pernicious anemia in Burkina Faso, collected over a 44-month period. The three criteria for diagnosis of pernicious anemia were: vitamin B12 deficiency, gastric disease (gastric histology) with presence of anti-intrinsic factor, and/or anti-gastric parietal cell antibodies in serum. All patients had anemia, with a mean hemoglobin level of 8.75 g/100 mL. The average mean corpuscular volume (MCV) was 122.1 fL the average mean corpuscular hemoglobin (MCH) 39.3 pg, the mean reticulocyte count 12.069 10(9)/L reticulocytes, and the mean rate of megaloblast marrow cells 17.2%. The serum vitamin B12 level ranged from 35 to 71 pmol/L. Antibodies against intrinsic factor were found in all eight patients. All ABO blood groups were present with a predominance (4 cases) of group O. Endoscopy found a normal fundic mucosa in three patients. Histology showed gastric atrophy and intestinal metaplasia for six patients (85.7%). Under B12 vitamin therapy, the course was favorable in all patients; seven patients also had 10 days of iron therapy. We recommend a gastric biopsy even in the absence of macroscopic gastric lesions on the upper gastrointestinal endoscopy. PMID:25787024

    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.

    Full Text Available O objetivo deste estudo de revisão bibliográfica é fornecer subsídios para o planejamento e avaliação de medidas de combate à anemia ferropriva. A necessidade de intervenções para o controle da prevalência da anemia ferropriva deve ser determinada pela magnitude da defi ciência nutricional e pelo conhecimento de seus efeitos na qualidade de vida, morbidade e mortalidade. A abordagem mais usual é fornecer ferro suplementar a gestantes, nutrizes e lactentes em programas de assistência primária à saúde, reconhecidamente os grupos de maior vulnerabilidade. A fortificação de alimentos e orientações sobre modificações da dieta representam medidas complementares e devem ser incrementadas.This review was elaborated in order to contribute to the planning of strategies for controlling iron deficiency anemia in developing countries. The need for intervention should be determined by the degree of iron deficiency in the individual group and knowledge of its effects on quality of life, morbidity, and mortality. The most frequent approach is to provide iron supplementation during pregnancy, lactation, and early childhood as a basic primary healthcare measure. Fortification and dietary modification are complementary approaches, and should be developed.

    Maintenance of the hematopoietic stem cell (HSC) compartment depends on the ability to metabolize exogenously and endogenously generated toxins, and to repair cellular damage caused by such toxins. Reactive aldehydes have been demonstrated to cause specific genotoxic injury, namely DNA interstrand cross-links. Aldehyde dehydrogenase 2 (ALDH2) is a member of a 19 isoenzyme ALDH family with different substrate specificities, subcellular localization, and patterns of expression. ALDH2 is localized in mitochondria and is essential for the metabolism of acetaldehyde, thereby placing it directly downstream of ethanol metabolism. Deficiency in ALDH2 expression and function are caused by a single nucleotide substitution and resulting amino acid change, called ALDH2*2. This genetic polymorphism affects 35-45% of East Asians (about ~560 million people), and causes the well-known Asian flushing syndrome, which results in disulfiram-like reactions after ethanol consumption. Recently, the ALDH2*2 genotype has been found to be associated with marrow failure, with both an increased risk of sporadic aplastic anemia and more rapid progression of Fanconi anemia. This review discusses the unexpected interrelationship between aldehydes, ALDH2 and hematopoietic stem cell biology, and in particular its relationship to Fanconi anemia. PMID:27650066

    Full Text Available La anemia de Fanconi (AF es un síndrome de inestabilidad cromosómica, autosómico recesivo, caracterizado por una hipersensibilidad del DNA a agentes clastogénicos. Clínicamente presenta una insuficiencia medular progresiva, diversas anomalías congénitas e incremento en la predisposición a padecer enfermedades malignas. Se han definido ocho grupos de complementación y se han clonado los genes correspondientes a seis de ellos. Recientes avances en biología molecular han permitido investigar la relación entre el genotipo de AF y la naturaleza y severidad del fenotipo clínico. El tratamiento de la AF es también objeto de una intensa investigación que actualmente se centra en el trasplante de progenitores hematopoyéticos, con éxito especialmente en caso de donante hermano HLA-idéntico, y en la terapia génica todavía en fase de investigación clínica.Fanconi’s anaemia (FA is an autosomal recessive syndrome associated with chromosomal instability, and hypersensitivity of the DNA to claustrogenic agents. Clinically it presents a progressive marrow insufficiency, different congenital anomalies and an predisposition to malignancy. Eight complementation groups have been defined and the genes corresponding to six of them have been cloned. Recent advances in molecular biology have made it possible to investigate the relationship between the FA genotype and the nature and severity of the clinical phenotype. The treatment of FA is also the object of intense research that is currently centred on the transplant of hematopoyetic progenitors, especially successful in cases of an HLA-identical brother or sister donor, and in gene therapy, which is still in the phase of clinical research.

    2011-11-01

    Anemia is a global public health problem. It has serious short- and long-term consequences during pregnancy and beyond. The anemic condition is often worsened by the presence of other chronic diseases such as malaria, tuberculosis, HIV, and diabetes. Untreated anemia also leads to increased morbidity and mortality from these chronic conditions as well. It is surprising that despite these chronic conditions (such as malaria, tuberculosis, and HIV) often being preventable, they still pose a real threat to public health. This article aims to review the current understanding of the pathophysiology, risks, prevention, and treatment of anemia in the light of these chronic conditions. PMID:22099433

    Full Text Available CLINICAL CASE We report a 64 year-old patient with fatigue and intermittent fever. Laboratory investigations revealed autoimmune haemolytic anemia. An abdomen CT scan showed a retroperitoneal mass near the left kidney. The CT scan guided mass biopsy was performed and its histology was diagnostic for a non Hodgkin B cell lymphoma. CONCLUSIONS The case describes autoimmume haemolytic anemia as a paraneoplastic syndrome associated with lymphoma. Autoimmume haemolytic anemia is a frequent paraneoplastic syndrome of lymphoproliferative disorders. The onset can be concomitant to the diagnosis of leukemia/lymphoma or follows the course of these neoplastic diseases or less frequently occurs years in advance.

    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.

    Executive dysfunction occurs in sickle cell anemia, but there are few early data. Infants with sickle cell anemia (n = 14) and controls (n = 14) performed the “A-not-B” and Object Retrieval search tasks, measuring precursors of executive function at 9 and 12 months. Significant group differences were not found. However, for the A-not-B task, 7 of 11 sickle cell anemia infants scored in the lower 2 performance categories at 9 months, but only 1 at 12 months (P = .024); controls obtained scores...

É considerada a principal consequência da deficiência de ferro - um nutriente que atua principalmente na síntese das células vermelhas do sangue e no transporte de oxigênio para as demais células do corpo. Este trabalho, realizado nos meses de março e abril de 2007, teve como objetivo avaliar as alterações hematológicas e os níveis de ferro sérico em crianças de 6 a 59 meses de idade na cidade de Campina Grande-PB. A prevalência de anemia observada foi de 31,73%, e, dentre as crianças anêmicas, 91% apresentaram quadro de anemia leve (Hb 9,0 g/dl. A faixa etária predominante em que se observou a menor concentração de hemoglobina foi de 6 a 12 meses (10,26 ± 1,27 g/dl. Considerando-se os vários parâmetros do hemograma para avaliar a etiologia ferropriva entre os anêmicos, o RDW (amplitude de distribuição dos eritrócitos foi o que mais apresentou especificidade no diagnóstico laboratorial da anemia por deficiência de ferro. Dessa forma, a investigação laboratorial é essencial para o diagnóstico precoce e para o acompanhamento terapêutico eficiente da anemia ferropriva em crianças.Anemia is a condition that is defined as a concentration of circulating hemoglobin at a level lower than that considered adequate by the World Health Organization (13 g/dL, 12 g/dL and 11 g/dL for men, women and children, respectively. It is considered the main consequence of iron deficiency - a nutrient that mainly acts in the synthesis of red blood cells and in the transportation of oxygen to other cells of the body. This study, which was performed in March and April 2007, aimed at evaluating hematologic alterations and serum iron levels in 6 to 59-month-old children in the city of Campina

    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. .

    Proper management of sickle cell anemia (SCA) begins with establishing the correct diagnosis early in life, ideally during the newborn period. The identification of affected infants by neonatal screening programs allows early initiation of prophylactic penicillin and pneumococcal immunizations, which help prevent overwhelming sepsis. Ongoing education of families promotes the early recognition of disease-released complications, which allows prompt and appropriate medical evaluation and therapeutic intervention. Periodic evaluation by trained specialists helps provide comprehensive care, including transcranial Doppler examinations to identify children at risk for primary stroke, plus assessments for other parenchymal organ damage as patients become teens and adults. Treatment approaches that previously highlighted acute vaso-occlusive events are now evolving to the concept of preventive therapy. Liberalized use of blood transfusions and early consideration of hydroxyurea treatment represent a new treatment paradigm for SCA management. PMID:23709685

    Pernicious anemia is an autoimmune disease with a variety of clinical presentations. We describe a case of pernicious anemia presenting with pancytopenia with hemolytic features. Further workup revealed very low vitamin B12 levels and elevated methylmalonic acid. It is important for a general internist to identify pernicious anemia as one of the cause of pancytopenia and hemolytic anemia to avoid extensive workup. Pernicious anemia can present strictly with hematological abnormalities without neurological problems or vice versa as in our case. PMID:27609735

As cadeias leves no plasma e na urina estavam elevadas, sobretudo a fração kappa e uma biópsia renal estudada por imunofluorescência e microscopia eletrônica confirmou o diagnóstico de Doença de Depósito das Cadeias Leves. A nefropatia de cadeia leve ocorre pela superprodução de cadeia leve de imunoglobulina produzida por linfócitos B com deposição nas membranas tubulares e no glomérulo.The authors present a case of a 65-year-old female patient, with chronic anemia associated with glomerulopathy manifested as proteinuria, cylindruria and renal failure. There were high serum and urinary levels of light chains and the diagnosis was performed by renal biopsy, examined using immunofluorescence and by electron microscopy that showed light chain paraproteins. Nephropathy of light-chain deposition disease occurs due to an over-production of light chains from immunoglobulins produced by B lymphocytes with a deposit in tubular and glomerular membranes.

    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.

    Full Text Available As anemias microcíticas e hipocrômicas atingem grande parcela da população mundial. Entre estas, significativa porcentagem de casos se deve à deficiência do ferro, enquanto em algumas regiões a frequência de talassemia menor se torna importante. Por outro lado, a anemia de doença crônica é a causa mais comum de anemia em pacientes hospitalizados. O diagnóstico diferencial destas doenças é clinicamente importante, e é atualmente realizado através dos exames padrão ouro envolvendo a avaliação do metabolismo do ferro e dosagem de HbA2. Embora dotados de grande utilidade, estes testes podem apresentar uma metodologia mais demorada e onerosa que, em casos de concomitância de doenças, comuns na prática clínica, não conseguem proporcionar um correto diagnóstico. Na tentativa de otimizar e direcionar o diagnóstico destas anemias, o uso de alguns parâmetros derivados dos modernos contadores automáticos tem sido sugerido. Neste estudo, o papel do RDW, parâmetros plaquetários (número de plaquetas, PDW, VPM e morfologia eritrocitária como parâmetros diferenciadores, foi avaliado em um grupo de 159 pacientes portadores de anemia microcítica e hipocrômica devido à deficiência do ferro, anemia de doença crônica e talassemia beta menor, comprovado pelos exames padrão ouro. Foi possível observar que o RDW não se mostrou um bom discriminante, enquanto o índice plaquetário PDW pode ser um parâmetro auxiliar no diagnóstico diferencial das anemias microcíticas e hipocrômicas. Com relação às alterações morfológicas dos eritrócitos, o pontilhado basófilo foi um achado bastante comum apenas em pacientes portadores de talassemia beta menor, com indícios de potencial utilidade na elucidação de casos de microcitose.Microcytic and hypochromic anemias affect many people worldwide. A significant percentage of cases are due to iron deficiency, while in certain regions the frequency of thalassemia minor is important

    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

    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 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

    2015-01-01

    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.

    Twenty cases of Dyphillobothrium pacificum (fish tapeworm) infections were prospectively studied to determine whether this tapeworm is associated with megaloblastic anemia, as commonly reported for D. latum infections. The most frequent symptoms were fatigue and mild abdominal pain, which were identified in approximately 66.6% of the 18 patients interviewed. Fourteen patients received treatment with niclosamide and all were cured. The other six patients spontaneously eliminated the tapeworms. One patient, who also had chronic diabetes and gastric atrophy, had low vitamin B12 levels and megaloblastic anemia. In all other patients, including three other patients with anemia, baseline vitamin B12 levels were in the reference range and did not significantly change when re-assessed three months later. Unlike D. latum, infection with D. pacificum is seldom associated with megaloblastic anemia or vitamin B12 deficit. PMID:22987655

    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.

    Full Text Available This study aimed to investigate the impact of the National Policy for the Integration of Disabled People in Brazil and to analyze which aspects of this policy are evidenced in academic publications. Data were collected in indexed databases and academic bibliography. The sample composition criteria permitted the inclusion of texts on social inclusion and public inclusion policies. Data were analyzed according to Thematic Content Analysis. It is concluded that disabled people have conquered a policy that guarantees access to goods and services, but face difficulties to achieve inclusion in education and the job market, due to the lack of education, qualification and resistance strategies by companies that refuse to hire them.

    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 ...

    ABSTRACT Sickle cell anemia is a genetic disease that primarily affects the black population. This anemia is due to a homozygous state of the abnormal hemoglobin S. An alteration occurs on the DNA molecule involving the substitution of the amino acid valine for glutamic acid at the sixth position on the beta polypeptide chain. This biochemical variation on the DNA molecule creates a physiological change that causes sickle-shaped red blood cells to be produced. The sickle-shaped cells are the ...

    Full Text Available Inherited thrombophilias are an important group of diseases that should be taken into account in the study of patients with thromboembolic disease, particularly in those whose clinical presentation includes frequent and recurrent thrombotic episodes at young age, in unusual sites, and a familial history of thrombosis. We report the case of a patient with C protein deficiency which developed deep venous thromboses of both legs when he was 36 and 37 years old. At 51 years of age he suffered from mesenteric thrombosis requiring surgical treatment and small intestine transplantation. His father had deep venous thrombosis. This is the first report of C protein deficiency in the Colombian literature. Other inherited thrombophilias such as the G20210A mutation in the prothrombin gene and actor V Leiden were absent. Se debe considerar un estado de hipercoagulabilidad primaria o trombofilia heredada en los pacientes con enfermedad tromboembólica venosa. La sospecha clínica se debe dirigir a los pacientes con presentación temprana, recurrente, familiar o en sitios anatómicos poco usuales. En este reporte se describe el caso de un paciente con déficit de proteína C de la coagulación, quien desarrolló trombosis venosa profunda del miembro inferior derecho a los 36 años y un año después, trombosis venosa profunda del miembro inferior izquierdo. A la edad de 51 años presentó trombosis de vasos mesentéricos que condujo a una resección intestinal extensa lo que obligó a un trasplante de intestino delgado. Su padre había presentado trombosis venosa de los miembros inferiores. Se descartó la presencia asociada de la mutación G20210A de la protrombina y del Factor V Leiden. Hasta donde sabemos, es el primer caso de deficiencia de proteína C de la coagulación informado en la literatura colombiana.

    2005-01-01

    Over 3 million people in the United States aged 65 years and older are anemic. This condition is associated with significant functional impairment and, perhaps, increased mortality. In March 2004, the American Society of Hematology (in conjunction with the National Institute of Aging) convened a "blue ribbon" panel of twenty physicians who are experts on various aspects of this topic. This paper highlights important consensus concepts resulting from that meeting. In particular, four areas of thought are shared. First, the epidemiology of anemia in the elderly is reviewed, including its definition, its expression in different racial groups, and its wide-ranging manifestations. Second, the pathophysiology of anemia in the elderly is reviewed as pertains to three general etiological categories (nutritional, chronic diseases, and so-called "unexplained" anemias). Particular emphasis is given to pathophysiologic mechanisms of anemia that are potentially unique to this age group. Third, a practical approach to the diagnosis and management of anemia for this patient population for the practicing hematologist is provided. Finally, the public health implications of anemia in the elderly for key stakeholder constituencies will be discussed in the oral presentation. PMID:16304431

    Full Text Available Anemia is one of the most frequent complications and/or extraintestinal manifestations of inflammatory bowel disease (IBD. Iron deficiency is the most important cause of anemia in Crohn’s disease and ulcerative colitis patients. Iron deficiency even without anemia may impact the quality of life of our IBD patients. In the last ten years the understanding of the pathophysiology of iron deficiency anemia and anemia of chronic diseases has increased, new diagnostic tools have been developed and new therapeutic strategies have been discussed. Hepcidin has been identified to be a central regulator of iron absorption from the intestine and of iron plasma levels. Hepcidin is regulated by iron deficiency but also as an acute phase protein by pro-inflammatory mediators such as interleukin-6. Innovative diagnostic tools with respect to iron metabolism have not been introduced in clinical routine or are not available for routine diagnostics. As iron substitution therapy is easy these days with a preference for intravenous substitution the impact of differential diagnosis of anemia in IBD patients is underestimated.

    Full Text Available Abstract Objective: To identify the prevalence and factors associated with anemia in children attending Municipal Early Childhood Education Day Care Center (Centros Municipais de Educação Infantil [CMEI] nurseries in Colombo-PR. Methods: Analytical, cross-sectional study with a representative sample of 334 children obtained by stratified cluster sampling, with random selection of 26 nurseries. Data collection was conducted through interviews with parents, assessment of iron intake by direct food weighing, and hemoglobin measurement using the finger-stick test. Bivariate association tests were performed followed by multiple logistic regression adjustment. Results: The prevalence of anemia was 34.7%. Factors associated with anemia were: maternal age younger than 28 years old (p = 0.03, male children (p = 0.02, children younger than 24 months (p = 0.01, and children who did not consume iron food sources (meat + beans + dark green leafy vegetables (p = 0.02. There was no association between anemia and iron food intake in CMEI. However, iron intake was well below the recommended levels according to the National Education Development Fund resolution, higher prevalence of anemia was observed in children whose intake of iron, heme iron, and nonheme iron was below the median. Conclusions: In terms of public health, the prevalence of anemia is characterized as a moderate problem in the studied population and demonstrates the need for coordination of interdisciplinary actions for its reduction in CMEI nurseries.

    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.

    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.

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 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.

    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

    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. PMID:26935626

    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.

    Full Text Available As crises de dor crônica ou aguda, de diferente intensidade e recorrência imprevisível, são um dos sintomas mais frequentes na Anemia Falciforme (AF e tendem a afetar a qualidade de vida dos portadores da doença. Este estudo procurou descrever e comparar a percepção do episódio doloroso da AF entre crianças e seus cuidadores. Participaram 27 pares de cuidador-criança, sendo 11 pares formados por crianças atendidas no Ambulatório de Pediatria do Hospital Universitário Cassiano Antônio de Moraes de Vitória/ES e 16 pares compostos por crianças que frequentavam o Hemocentro de Cuiabá/MT. Os resultados revelaram diferença na percepção de cuidador e criança sobre a caracterização da dor no que se refere ao tipo e à intensidade. As crises de dor interferem, sobretudo, nas atividades do cotidiano. A estratégia de enfrentamento mais utilizada por ambos os grupos centrou-se em pensamentos que envolveram os aspectos negativos da experiência indesejada, o que indica a necessidade de intervenção psicológica com esta população

    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.

    Full Text Available A anemia na insuficiência renal crônica deve-se à redução da produção de eritropoetina, devido à diminuição da massa renal funcionante. A eritropoetina tem sido preconizada para o tratamento da anemia, no entanto, cerca de 5% dos pacientes são resistentes à mesma. A resistência à eritropoetina é definida como a necessidade do uso de uma dose maior que 12.000U/kg por semana, sem atingir o hematócrito alvo de 33% a 36%. As citocinas pró-inflamatórias têm uma associação importante com a anemia resistente ao tratamento com eritropoetina (EPO. A pentoxifilina tem sido usada para inibir a produção dessas citocinas pró-inflamatórias. Este estudo foi realizado com os pacientes sob hemodiálise no Instituto de Nefrologia Ribamar Vaz, do Hospital da Santa Casa de Misericórdia de Maceió-Al. Os pacientes com diagnóstico de resistência à eritropoetina receberam pentoxifilina na dose de 400 mg VO, após hemodiálise por seis meses. Avaliamos o hematócrito e a proteína C reativa (PCR em dois momentos: ao final de três meses com 12 pacientes e, ao final de seis meses, com sete pacientes. A média de PCR dos 12 pacientes, no primeiro mês, foi de 5,65 mg/l. No terceiro mês, de 2,58 mg/l. Porém, no sexto mês, considerando apenas os sete que terminaram o projeto, foi de 4,55 mg/l. Não foi observada diferença significativa. A média final dos hematócritos(Htc observada nos pacientes foi de 28,74 %. A média dos Htc na avaliação de seis meses que precederam o início do projeto, foi de 26,22%. Não foi observada diferença estatisticamente significante, quer nos 12 pacientes acompanhados por três meses ou nos sete que conseguiram concluir o estudo. Não observamos correlação entre os níveis de PCR e os de hematócrito. No entanto, em nossa amostragem, a média de PCR basal não estava elevada e este pode ter sido um fator importante nos resultados díspares em relação aos dados da literatura. Sendo assim, conclu

    Full Text Available O diagnóstico diferencial das anemias microcíticas é complexo e sua investigação laboratorial, de custo elevado. O uso de índices hematimétricos para racionalizar a abordagem diagnóstica tem sido proposto para contornar essa problemática. OBJETIVO: Avaliar a utilidade diagnóstica dos índices hematimétricos nas anemias microcíticas, de modo prospectivo, em hospital geral de alta complexidade. MÉTODOS: Foram analisados 2278 hemogramas realizados nos nossos serviços. Baseados em eletroforese de hemoglobina e ferritina, estratificamos 52 pacientes adultos com anemia microcítica em três grupos: Anemia ferropriva (AF; n=26 pacientes, Beta-Talassemia Menor (BTM; n=17 e Anemia não-ferropriva e não-beta-Talassemia (ANFNT; n=9. Avaliamos o uso dos seguintes índices hematimétricos na discriminação dos três grupos, por análise de variância e curvas ROC: RBC, VCM, HCM, RDW, índices de England e de Green. RESULTADOS: Nenhum dos índices permitiu a separação integral dos três grupos. Determinamos valores de corte para cada um dos índices e calculamos sensibilidade (S, especificidade(E, valores preditivos positivo e negativo e eficácia, em função de sua melhor discriminação. A discriminação de BTM foi melhor realizada pelo RBC acima de 5 milhões/mL, com S=82,3% e E=82,8%; enquanto a anemia ferropriva, pelo RDW acima de 16%, mas com S de apenas 69,2% e E=80,7%. CONCLUSÕES: A anemia ferropriva apresenta difícil diagnóstico presuntivo pelos índices, devendo ser realizada confirmação laboratorial.

Investigou-se a realidade vivida por 80 pacientes adultos (49 mulheres e 31 homens com diagnóstico de anemia falciforme, seguidos regularmente em centro hematológico. O diagnóstico tardio da doença foi um dos principais aspectos detectados na casuística examinada. Observou-se que a problemática maior do paciente adulto com a anemia falciforme esta centrada nos aspectos econômicos, sobretudo na falta de oportunidades profissionais, apesar de os mesmos poderem participar do mercado de trabalho, desde que estejam recebendo tratamento médico adequado e exerçam funções compatíveis com as suas limitações e potencialidades. A orientação psicoterapêutica teve uma grande aceitação pelos pacientes, sem diferença significativa entre os sexos.

RELATO DEL CASO: Paciente de 24 años, portadora de anemia microcítica, enfermedad de von Willebrand y HIV, llegó a la emergencia obstétrica en inicio de trabajo de alumbramiento. No realizó prenatal. Fue indicada cesárea a fin de disminuir los riesgos de transmisión vertical en paciente con carga vírica de HIV desconocida. Presentaba hematomas por el cuerpo e historia de hematoma de pared abdominal en cesárea anterior. Los tests de coagulación estaban un poco alterados. Después de infusión de concentrado de factor VIII fue realizada anestesia general. Madre y recién nacido presentaron evolución satisfactoria. CONCLUSIONES: La evaluación de manifestaciones clínicas en pacientes con coagulopatia es fundamental en la decisión del tipo de anestesia que será indicada para cada paciente. La evaluación debe ser individualizada, considerando los riesgos y beneficios de la técnica escogida. En estas pacientes, se debe siempre restringir al máximo la indicación de interrupción de la gestación por vía alta, optándose siempre por los métodos menos invasivos. La terapia con concentrado de factor VIII es actualmente la mejor opción de tratamiento, corrigiendo la deficiencia específica y dismunuyendo los riesgos de transmisión vírica.BACKGROUND AND OBJECTIVES: Von Willebrand's disease is the most common hereditary coagulation disorder in young women.

    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 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.

  12. CORD SERUM FERRITIN AS BIOCHEMICAL MARKER IN IRON DEFICIENCY ANEMIA

    Full Text Available Iron deficiency anemia is by far the most frequent type of anemia seen in pregnancy, accounting for 90% or more of all cases. Iron deficiency anemia has adverse consequences on infant development. Therefore maternal anemia should be prevented and treated. Serum ferritin is the single best non-invasive test and is a very useful and reliable index of iron stores especially during pregnancy, with low levels indicating iron deficiency. While infants born to anemic mother are themselves not anemic, they do not suffer from low iron stores. The main aim of the study is to establish cord serum ferritin as a biochemical marker in iron deficiency anemia. The specific objectives of this study is to estimate cord and maternal serum ferritin in the last trimester of pregnancy and to correlate it with hematological parameters. Cord serum ferritin levels were normal in the patients under study, even when the maternal serum ferritin levels were decreased. The mean level of cord serum ferritin was 134.06ng/ml and maternal serum ferritin was 41.65ng/ml and was statistically significant. The hematological parameters like hemoglobin, hematocrit, MCV and MCHC were also decreased in the patients with low serum ferritin and were found to be statistically significant. Hence estimation of cord serum ferritin can be used as a biochemical marker to assess iron deficiency in the early stages itself and thereby neurodevelopmental complications in children can be prevented.

    Sideroblastic anemia is an anemic condition characterized by chronic hypochromic anemia and the presence of large iron deposits in erythroid cells. Seven dogs with sideroblastic anemia were evaluated retrospectively. Historical, clinical, and clinicopathologic findings were reviewed to determine whether the condition was idiopathic or associated with disease conditions or drug or toxin exposure. Associated diseases were identified in 6 affected dogs and included acute hepatitis, pancreatitis, acute hepatitis and pancreatitis, inflammatory disease, glomerulonephritis, and myelofibrosis. None of the dogs had a history of recent exposure to drugs or toxins. One dog had no evidence of associated disease. Regardless of the associated disease condition, sideroblastic anemia was characterized by moderate to severe nonregenerative and frequently hypochromic anemia with prominent dysplastic features in bone marrow that were most prominent in the erythroid series. Survival varied from days to years. Identification of large numbers of siderocytes or sideroblasts in blood or bone marrow is inconsistent with a diagnosis of iron deficiency and should prompt a search for inflammatory disease conditions, including hepatitis, pancreatitis, and glomerulonephritis.

    Full Text Available Malaria is a vector born infectious disease that represents an enormous health and socio-economic burden worldwide, particularly for communities from tropical and subtropical regions, where more than 500 million of clinical cases are recorded every year. Human malaria is produced by four different Plamodium species, from which P. falciparum and P. vivax are the prevalent species. The clinical manifestations of malaria are very pleomorphic and could range from febrile episodes of short duration if an effective and opportune treatment is installed, to severe systemic complications and death. One of the most frequent and severe, malaria complication is anemia that represents one of the major obstacles for the development of endemic areas, due to its negative impact for children performance at school as well as for adult productivity. The physiopathology of anemia is poorly understood, but it is accepted that the overall anemia burden is produced through multiple mechanisms that include the destruction of both infected and non-infected red blood cells, erythrophagocytoses and a potential arrest of erythropoyesis. Anemia contributes significantly to the severity of malaria and to its mortality. Here we review the current understanding of the mechanisms involved in the production of malaria related anemia, its treatment and the potential implications of malaria vaccines in the prevention of this complication.

    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.

    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. PMID:24678166

    Chronic anemia develops over a course of weeks to months and is usually mild to moderate in nature. It is important to understand the etiology of the reduced number of circulating red blood cells to treat the anemia appropriately. Diagnosis is dependent on patient history and laboratory findings, such as complete blood counts, iron studies, a peripheral smear, and occasionally, a bone marrow biopsy. Treatment modalities frequently administered by infusion therapy nurses include treatment of the underlying chronic disease, replacement of deficiencies (iron, vitamin B12, folate, or erythropoietin), or transfusion of red blood cells. Infusion therapy nurses play a vital role in the assessment and delivery of medication therapy to patients with chronic anemia. PMID:26339940

    Iron deficiency and iron deficiency anemia are global health problems leading to deterioration in patients' quality of life and more serious prognosis in patients with chronic diseases. The cause of iron deficiency and anemia is usually a combination of increased loss and decreased intestinal absorption and delivery from iron stores due to inflammation. Oral iron is first line treatment, but often hampered by intolerance. Intravenous iron is safe, and the preferred treatment in patients with chronic inflammation and bowel diseases. The goal of treatment is normalisation of hemoglobin concentration and recovery of iron stores. It is important to follow up treatment to ensure that these objectives are met and also long-term in patients with chronic iron loss and/or inflammation to avoid recurrence of anemia.

The laboratory findings revealed hemolytic anemia and direct antiglobulin test was positive. With a diagnosis of autoimmune hemolytic anemia (AIHA, prednisolone was started but was ineffective after 1 month of therapy. A bone marrow trephine biopsy revealed pure red cell aplasia (PRCA showing severe erythroid hypoplasia. The case was considered PRCA following AIHA. This combination without clear underlying disease is rare. Human parvovirus B19 infection was not detected in the marrow aspirate during reticulocytopenia. The patient received azathioprine, and PRCA improved but significant hemolysis was once again documented with a high reticulocyte count. The short time interval between AIHA and PRCA phase suggested an increased possibility of the evolution of a single disease.

    A gastric intrinsic factor output under 200 U/h after pentagastrin stimulation (N > 2000 U/h) is specific for pernicious anemia. The other findings are either variable or non specific. Serum intrinsic factor antibodies, considered as specific in general practice, are present only in half of the patients with pernicious anemia. In their absence, since the disappearance of the Schilling tests, the gastric tubage currently used for the study of gastric acid secretion, is obligatory for the simultaneous study of intrinsic factor output. This study is important to eliminate another disease much more frequent than pernicious anemia, the protein bound to cobalamin malabsorption was observed in achlorhydric simple atrophic gastritis in the presence of intrinsic factor secretion.

  14. Glycine and Folate Ameliorate Models of Congenital Sideroblastic Anemia.

    Directory of Open Access Journals (Sweden)

    J Pedro Fernández-Murray

    2016-01-01

    Full Text Available Sideroblastic anemias are acquired or inherited anemias that result in a decreased ability to synthesize hemoglobin in red blood cells and result in the presence of iron deposits in the mitochondria of red blood cell precursors. A common subtype of congenital sideroblastic anemia is due to autosomal recessive mutations in the SLC25A38 gene. The current treatment for SLC25A38 congenital sideroblastic anemia is chronic blood transfusion coupled with iron chelation. The function of SLC25A38 is not known. Here we report that the SLC25A38 protein, and its yeast homolog Hem25, are mitochondrial glycine transporters required for the initiation of heme synthesis. To do so, we took advantage of the fact that mitochondrial glycine has several roles beyond the synthesis of heme, including the synthesis of folate derivatives through the glycine cleavage system. The data were consistent with Hem25 not being the sole mitochondrial glycine importer, and we identify a second SLC25 family member Ymc1, as a potential secondary mitochondrial glycine importer. Based on these findings, we observed that high levels of exogenous glycine, or 5-aminolevulinic acid (5-Ala a metabolite downstream of Hem25 in heme biosynthetic pathway, were able to restore heme levels to normal in yeast cells lacking Hem25 function. While neither glycine nor 5-Ala could ameliorate SLC25A38 congenital sideroblastic anemia in a zebrafish model, we determined that the addition of folate with glycine was able to restore hemoglobin levels. This difference is likely due to the fact that yeast can synthesize folate, whereas in zebrafish folate is an essential vitamin that must be obtained exogenously. Given the tolerability of glycine and folate in humans, this study points to a potential novel treatment for SLC25A38 congenital sideroblastic anemia.

    Full Text Available Neil D Goldberg Emeritus Chief of Gastroenterology, University of Maryland St. Joseph Medical Center, Towson, MD, USA Abstract: Iron deficiency anemia is the most common form of anemia worldwide, caused by poor iron intake, chronic blood loss, or impaired absorption. Patients with inflammatory bowel disease (IBD are increasingly likely to have iron deficiency anemia, with an estimated prevalence of 36%–76%. Detection of iron deficiency is problematic as outward signs and symptoms are not always present. Iron deficiency can have a significant impact on a patient's quality of life, necessitating prompt management and treatment. Effective treatment includes identifying and treating the underlying cause and initiating iron replacement therapy with either oral or intravenous iron. Numerous formulations for oral iron are available, with ferrous fumarate, sulfate, and gluconate being the most commonly prescribed. Available intravenous formulations include iron dextran, iron sucrose, ferric gluconate, and ferumoxytol. Low-molecular weight iron dextran and iron sucrose have been shown to be safe, efficacious, and effective in a host of gastrointestinal disorders. Ferumoxytol is the newest US Food and Drug Administration-approved intravenous iron therapy, indicated for iron deficiency anemia in adults with chronic kidney disease. Ferumoxytol is also being investigated in Phase 3 studies for the treatment of iron deficiency anemia in patients without chronic kidney disease, including subgroups with IBD. A review of the efficacy and safety of iron replacement in IBD, therapeutic considerations, and recommendations for the practicing gastroenterologist are presented.

    Full Text Available Background: Human immunodeficiency virus (HIV prevalence is high among rural dwellers and pregnant women. Aims: This study aims to determine the prevalence of HIV and anemia among pregnant women attending antenatal clinic in rural community of Okada, Edo State, Nigeria. Patients and Methods: Anticoagulated blood and sera samples were obtained from 480 women consisting of 292 pregnant and 188 non-pregnant women. Antibodies to HIV were detected in the sera samples and hemoglobin concentration of the anticoagulated blood specimens were determined using standard techniques. Anemia was defined as hemoglobin concentration <11g/dl for pregnant women and <12g/dl for non-pregnant women. Results: Pregnancy was not a risk factor for acquiring HIV infection (pregnant vs. non-pregnant: 10.2% vs. 13.8%; OR=0.713, 95% CI=0.407, 1.259, P = 0.247. The prevalence of HIV was significantly (P = 0.005 and P = 0.025 higher in the age group 10-20 years and 21 - 30 years among pregnant and non-pregnant women respectively. Pregnancy was a risk factor for acquiring anemia (OR=1.717, 95% CI=1.179, 2.500, P = 0.006. Only the age of pregnant women significantly (P = 0.004 affected the prevalence of anemia inversely. Conclusion: The prevalence of HIV and anemia among pregnant women were 10.2% and 49.3% respectively. Pregnancy was associated with anemia. Interventions by appropriate agencies are advocated to reduce associated sequelae.

    The prevalence of celiac disease (CD) appears to be increasing in the United States. However, the proportion of new CD cases with atypical presentations is also rising. We present the case of a 49-year-old woman who was diagnosed with CD in the setting of new, severe iron-deficiency anemia, 13 years into treatment of diarrhea-predominant irritable bowel syndrome associated with chronic mildly elevated liver function tests. While CD and iron deficiency anemia are common, this is a rare present...

    An adult with a large patent ductus arteriosus may present with fatigue, dyspnea or palpitations or in rare presentation with endocarditis. The case illustrated unique role of vegetation of endocarditis in hemolytic anemia in adult with patent ductus arteriosus (PDA). Despite treatment of endocarditis with complete course of appropriate antibiotic therapy and normality of C- reactive protein, erythrocyte sedimentation rate and leukocytosis and wellness of general condition, transthoracic echocardiography revealed large vegetation in PDA lumen, surgical closure of PDA completely relieved hemolysis, and fragmented red cell disappeared from peripheral blood smear. The 3-month follow-up revealed complete occlusion of PDA and abolishment of hemolytic anemia confirmed by clinical and laboratory examination.

    Full Text Available Anemia is common in critically ill patients. As a consequence packed red blood cell (PRBC transfusions are frequent in the critically ill. Over the past two decades a growing body of literature has emerged, linking PRBC transfusion to infections, immunosuppression, organ dysfunction, and a higher mortality rate. However, despite growing evidence that risk of PRBC transfusion outweighs its benefit, significant numbers of critically ill patients still receive PRBC transfusion during their intensive care unit (ICU stay. In this paper, we summarize the current literature concerning the impact of anemia on outcomes in critically ill patients and the potential complications of PRBC transfusions.

    Full Text Available Imerslund Grasbeck syndrome (IGS is a rare autosomal recessive childhood disorder characterized by selective Vitamin (vit B 12 malabsorption with asymptomatic proteinuria without any structural renal pathology. The patients stay healthy for decades with life-long parenteral vit B12. We report a case of young female who presented with pancytopenia and proteinuria, evaluated in local hospitals as chronic hemolytic anemia (autoimmune cause, finally diagnosed as IGS on complete evaluation. She was treated with injectable vit B12 (1000 μg cyanocobalalmin and showed drastic recovery. IGS should be considered in patients with megaloblastic anemia not responding to oral vit B12 and associated proteinuria.

    Full Text Available Foram estudados 10 doentes, portadores de anemia ancilostomótica e de grande parasitose. Foram determinados alguns parâmetros hematológicos como dosagem de hemoglobina, contagem de hemácias, hematócrito, volume corpuscular médio, hemoglobina corpuscular média, ferro sérico e siderofilina. Foram estudados o volume da perda de sangue intestinal, o ferro perdido nesta hemorragia e eliminado nas fezes, e o ferro reaborvido da hemorragia intestinal. Conclui-se que a reabsorção do ferro da hemoglobina por dia no tubo digestivo é de suma importância no retardamento da instalação da anemia ferropriva, causada pela parasitose ancilostomótica.Ten patients presenting ancylostomotic anemia and a high rate of parasitosis were submitted to several hematologic determinations: hemoglobin level, erythrocyte count, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, serum iron level, and transferrin. In addition, measurements were made of the blood volume lost by intestinal bleeding, of iron loss through hemorrhage and in feus, and of iron reabsorption from intestinal bleeding. The main reason for the late appearance of iron deficiency anemia in ancylostomiasis is the high degree of dally iron absorption in the digestive tract, originating from hemoglobin breakdown.

    Full Text Available O diagnóstico diferencial das anemias microcíticas é clinicamente importante. Na tentativa de tornar esse diagnóstico menos oneroso e mais eficiente, o uso de parâmetros dos contadores automáticos tem sido sugerido. O objetivo deste estudo foi avaliar a eficiência diagnóstica de alguns parâmetros do hemograma na diferenciação das anemias microcíticas. Foram comparados os parâmetros hematológicos de 395 pacientes portadores de anemia ferropriva, anemia de doença crônica ou talassemia menor. O número de hemácias apresentou os maiores valores combinados de sensibilidade e especificidade na diferenciação dessas anemias. Em conclusão, a contagem de hemácias pode ser útil no diagnóstico diferencial de anemias microcíticas.Differential diagnosis of microcytic anemia is clinically important. In an attempt to make this diagnosis more cost-effective, the use of some parameters obtained from automated blood count analyzers has been suggested. The objective of this study was to evaluate the efficiency of blood count parameters in differentiating microcytic anemias. Blood parameters were compared in 395 patients with iron deficiency anemia, chronic disease anemia or thalassemia minor. The number of red blood cells showed the highest combined sensitivity and specificity in differentiating these anemias. Hence, blood counts may be a useful tool in the differential diagnosis of microcytic anemias.

    Full Text Available Pernicious anemia is an autoimmune disease with a variety of clinical presentations. We describe a case of pernicious anemia presenting with pancytopenia with hemolytic features. Further workup revealed very low vitamin B12 levels and elevated methylmalonic acid. It is important for a general internist to identify pernicious anemia as one of the cause of pancytopenia and hemolytic anemia to avoid extensive workup. Pernicious anemia can present strictly with hematological abnormalities without neurological problems or vice versa as in our case.
