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. La piruvato quinasa es una de las enzimas regulatorias esenciales de la glicólisis anaeróbica, la deficiencia de esta enzima causa una destrucción prematura de los eritrocitos. El presente es un estudio de caso y relata los hallazgos clínicos y paraclínicos en un perro brasileño de la raza West Highland White Terrier (WHWT con historia de debilidad e intolerancia al ejercicio.

    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 anemia es un problema de salud pública a nivel mundial. En Paraguay, existen datos limitados sobre la frecuencia de anemia en mujeres en edad reproductiva no gestantes. Este estudio piloto descriptivo de corte transverso tuvo como objetivo determinar la frecuencia de anemia y deficiencia de hierro, el estado nutricional, hábitos alimentarios y tóxicos en 99 mujeres no gestantes en edad reproductiva de 18 a 48 años que acudieron al Hospital Regional de Villa Hayes en Octubre del 2.014. La anemia se determinó tomando como punto de corte una concentración de hemoglobina <12 g/dL. La deficiencia de hierro se evaluó según la saturación de la transferrina. Además, se evaluó el índice de masa corporal (IMC y los hábitos nutricionales a través de una encuesta. La frecuencia de anemia fue de 15,1% (IC95% 8,7-23,8%, de éste el 33,3% (IC95% 12,8-61,6% correspondió a anemia ferropénica. Se observó asociación entre la presencia de anemia y los niveles disminuidos tanto del hematocrito (<38% como del número de glóbulos rojos (<4,2x 106/uL. Todas las mujeres con anemia ferropénica tenían peso <64 kg e IMC <24,5 kg/m2. Además, se detectó una alta frecuencia de sobrepeso y obesidad (45,4%, alto consumo de grasas, y bajo consumo de legumbres, frutas y verduras. A partir de estos resultados, se sugiere mantener la vigilancia e implementar programas que incluyan a estas mujeres, tanto para evitar deficiencias nutricionales como excesos.

    Full Text Available La degeneración combinada subaguda es un desorden neurológico que afecta los cordones posteriores de la médula y se manifiesta precozmente con disestesia, parestesias y astenia severa. En pacientes de riesgo, es la manifestación inicial (y a veces única de una deficiencia de vitamina B12. El cerebro, el nervio óptico y los nervios periféricos pueden afectarse igualmente. Presentamos catorce casos de degeneración combinada subaguda por deficiencia de vitamina B12, con niveles bajos y anemia en la mayor parte de pacientes. Una revisión de la literatura muestra también estados carenciales en grupos poblacionales pobres de adultos mayores con otros factores de riesgo; y deficiencias subclínicas con depósitos hepáticos de vitamina B12 casi exhaustos. Puede haber clínica neuropsiquiátrica en casos sin niveles bajos de vitamina B12 ni anemia.

    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. Después de la repleción de hierro y

    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.

    Full Text Available Resumen:IntroducciónNumerosos estudios mostraron que la deficiencia nutricional durante la vida fetal y posnatal predisponen al desarrollo de patologías en la vida adulta, como la hipertensión arterial y las enfermedades renales. La distribución ubicua del cinc y sus propiedades químicas determinan su esencialidad en los sistemas biológicos.ObjetivosEvaluar si las alteraciones renales y cardiovasculares en la vida adulta inducidas por la restricción moderada de cinc durante la vida fetal, la lactancia y/o el crecimiento se asocian con cambios en el sistema del óxido nítrico.Material y métodosRatas Wistar hembra recibieron durante la preñez hasta el destete de las crías una dieta control o una baja en cinc. 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.

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

    Full Text Available 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.

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.

    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.

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.

    Full Text Available Relatamos caso raro de anemia hemolítica microangiopática em paciente após transplante hepático por cirrose Child B causada por deficiência de alfa1-antitripsina. Após análise clínica e laboratorial extensa, concluiu-se que o quadro de hemólise foi causado pela medicação imunossupressora utilizada após transplante. Inicialmente foi utilizado tacrolimus que, posteriormente, foi substituído por ciclosporina A, entretanto não houve melhora da hemólise. Após suspensão das duas drogas, houve melhora importante clínica do paciente, com normalização dos parâmetros hematológicos.We report a rare case of acute hemolysis in a patient after liver transplant for Child B cirrhosis caused by alfa1-antitripsine deficiency. History and laboratorial examinations indicated that the most probable cause of the hemolysis was the use of the immunosupressor tacrolimus and later Cyclosporine A. After the discontinuation of these drugs, there was improvement in the clinical condition of the patient, with a compensated hemolytic anemia.

    Full Text Available A anemia que se processa em caes quando se administra grandes doses de benzoato de estradiol, nao parece ser produzida por processes conhecidos de destrui?ao intra-organica. Esta substantia paraliza os fenomenos de rege¬nerate hematica, parece interferir por processo desconhecido na fisiologia sanguinea, produz graves lesoes na rede circulatoria que irriga a mucosa do intestino, principalmente jejuno, ocasipnando nesse orgao «extravasamento variavel de sangue, fator seguramente coadjuvante na formação da anemia.The characteristic findings in the pathological picture presented by 60 dogs when administered large doses of estradiol benzoate subcutaneously in an oil vehicle are: thrombocytopenia, aplastic anemia, which follows a brief latent period, intestinal tract haemorrhages, haemorrhagic lesions occurring principally in the mucosa of the jejunum, followed by prostration and death generally within 1 to 3 weeks. Irregular findings are leucocytosis, purpuric skin lesions, visceral haemorrhages and pyoid bone marrow. The total circulating hemoglobin was determined in 9 dogs before and after the anemia was established, thus verifying the total hemoglobin loss. The blood loss through intestinal haemorrhages during the observation period was determined by benzidine test. The quantity of hemoglobin recovered from the feces in the form of hematin varied between 30 and 70% of the total hemoglobin which disappeared from the circulation. In order to ascertain the degree of intra-organic blood destruction the bilirubin eliminated in the urine of dogs with gall-bladder renal type of fis¬tula was determined daily and these values compared with those obtained for normal animals. The blood destruction as measured by this method was practically nil. An attempt was made to determine whether the presence of large quan¬tities of blood in the intestine might exert a paralyzing effect on the regene¬ration of hemoglobin in dogs rendered anemic through

Se evaluó el efecto de la deficiencia de nitrógeno y de fósforo sobre el perfil de APs en inflorescencias de esta maleza. Se realizó un ensayo utilizando un diseño completamente aleatorizado con 10 repeticiones, en el cual las plantas, que crecieron en hidroponia desde mayo hasta octubre, fueron regadas con solución de nutrientes en las que las concentraciones de N o de P reducidas en un 50% respecto del control. La cuantificación de APs en las inflorescencias de S. grisebachii por CG y CG-EM, demuestra un aumento significativo en el contenido total de APs, en los tratamientos con déficit en N o P (1,33 y 1,34 mg g-1 de materia seca, respectivamente, comparados con el control 0,35 mg g-1. Se identificaron siete APs y sus concentraciones variaron entre tratamientos. Senecionina resultó el alcaloide mayoritario en el tratamiento déficit de N, mientras senecifilina resultó más abundante en los tratamientos control y con déficit de P, seguidos en todos los casos por integerrimina y cantidades menores de espartiodina, jacobina, jacozina y retrorsina.Senecio grisebachii Baker is a weed that invades natural pastures and crops in southern Brazil, Uruguay, the mesopotamic provinces and Buenos Aires in Argentina, and is considered to be toxic because of the presence of pyrrolizidine alkaloids (PAs in its tissues.

    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

Após um período de 3 a 5 dias em que os animais tiveram hemoglobinúria e anemia acentuadas, apesar de continuarem a receber a planta (durante um total de 12 a 14 dias, em três dos quatro animais esses sintomas desapareceram. Verificou-se nesses casos uma rápida recuperação dos valores hemáticos logo que cessou a hemoglobinúria. O quarto bovino, que recebeu 2,5 g/kg/dia durante 5 dias, morreu no 8° dia, tendo apresentado durante os últimos 4 dias de vida hemoglobinúria e anemia acentuadas. À necropsia e nos exames histopatológicos deste animal foram verificadas nefrose hemoglobinúrica e distrofia hepática com necrose centrolobular do parênquima. Dose de 7,7 g/kg única ou quantidades de 2,5 e 3 g/kg/dia administradas durante 2 dias seguidos, causaram em três outros bovinos quadro clínico de cólica, com morte em questão de horas, verificando-se à necropsia acentuado edema da parede do rúmen e do retículo.

    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.

    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.

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

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 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.

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

    Full Text Available Introducción: La malaria, la anemia y la parasitosis intestinal coexisten y constituyen problemas de salud pública en Colombia. Datos disponibles en la literatura biomédica llevan a pensar que estos problemas no son aislados sino que están interrelacionados. Por otra parte, los suplementos de retinol han sido efectivos para reducir la mortalidad infantil, con disminución de complicaciones en niños palúdicos, posiblemente por efectos del retinol sobre la función inmune, desviando la respuesta de citocinas hacia un patrón TH2, que también protege de desarrollar anemia grave. Esta revisión tiene como objetivo describir parte de las relaciones vistas en la literatura biomédica mundial, entre retinol y malaria, retinol y anemia, retinol, malaria y parasitosis intestinal, anemia y malaria y mostrar la mediación de estas interrelaciones por el patrón de citocinas TH1/TH2 en sujetos con malaria.Metodología: Se consultaron las siguientes bases de literatura biomédica: Medline, Lilacs, Spingerlik, Md Consultant, Web of Science, Ovid, Scient Direct, Ebsco y Cochrane.

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.

    2006-01-01

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

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

    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.

    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

    2013-06-01

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

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

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

    Full Text Available 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.

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

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

    As the population ages, increasing attention has become focused on the prevalence of anemia in elderly individuals. Anemia occurs in more than 10% of individuals who are older than the age of 65 years, and it increases to more than 50% in individuals who are older than the age of 80 years. Although the anemia is typically mild and unlikely to result in symptoms, it is uniformly associated with increased morbidity and mortality as assessed in large cohort studies. Anemia is an independent pred...

The aim of this paper is to study further the relationship between ocular and renal lesions and biochemical alterations in rats fed a choline-deficient diet. Fifty one weanling male Wistar rats, were divided into two groups. Thirty one of them were fed a choline-deficient diet and the rest was fed a choline-supplemented diet ad libitum. Animals from both groups were killed between the fifth and the eighth day. Urea, creatinine and homocysteine concentrations in blood were determined. Eyes were used for light microscopy study; high resolution light microscopy and the study of the retina as "rétine a plat". Kidneys were studied by light microscopy. Choline-supplemented rats did not show ocular or renal lesion. Choline-deficient rats that showed renal lesions, tubular or cortical necrosis, did not always have ocular changes. There were no ocular changes in the only choline-deficient rat without renal lesion. The ocular changes consisted mainly in haemorrhage in both cameras and ciliary and vitreous bodies.

    2015-10-01

    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.

  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.

    Iron refractory iron deficiency anemia is a hereditary recessive anemia due to a defect in the TMPRSS6 gene encoding Matriptase-2. This protein is a transmembrane serine protease that plays an essential role in down-regulating hepcidin, the key regulator of iron homeostasis. Hallmarks of this disease are microcytic hypochromic anemia, low transferrin saturation and normal/high serum hepcidin values. The anemia appears in the post-natal period, although in some cases it is only diagnosed in ad...

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

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

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

    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.

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

    2015-01-01

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

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.

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

    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.

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

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

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

    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.

  11. Warm autoimmune hemolytic anemia.

    2015-06-01

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

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

    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

  2. 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.

    ífico en la mezcla administrada (p.e., hierro. La deficiencia funcional de hierro (DFH causada por la inflamación no es sólo una de las causas de anemia en el paciente crítico, sino que también induce una respuesta inapropiada del sistema inmunitario, lo que origina una mayor duración de los episodios de respuesta inflamatoria sistémica y un peor pronóstico. Objetivo: Este estudio transversal prospectivo se inició para evaluar la prevalencia de DFH en pacientes críticos durante su estancia en la UCI, y determinar la población de pacientes que podrían beneficiarse de la administración de hierro. Métodos: Se realizaron recuentos hematológicos completos, incluyendo reticulocitos (RETIC, y determinación de los niveles séricos de hierro (SI, transferrina (TRF y porcentaje de saturación (satTRF, receptor soluble de TFR (sTfR, ferritina (FRT y proteína C-reactiva (CRP en muestras de sangre venosa de 131 pacientes ingresados en UCI durante al menos 24 horas (estancia en UCI, min: 1 día; max: 38 días. Resultados: Se detectó la presencia de anemia (Hb 2,3 mg/dL en el 13%; y de CRP 2,3. Dado que el tratamiento con hierro oral parece ser inefectivo, estos pacientes podrían beneficiarse de la terapia con hierro intravenoso para la corrección de su deficiencia real o funcional de hierro, lo que a su vez podría contribuir a una disminución de su estado inflamatorio.

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

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

    2009-10-07

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

    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.

  17. Hereditary sideroblastic anemia: pathophysiology and gene mutations.

    Science.gov (United States)

    Harigae, Hideo; Furuyama, Kazumichi

    2010-10-01

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

  1. Management of Iron Deficiency Anemia

    Science.gov (United States)

    Jimenez, Kristine; Kulnigg-Dabsch, Stefanie

    2015-01-01

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

    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.

    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.A case of a male with chronic neutropenia and human immunodeficiency virus infection is presented along, with a review of possible pathogenic mechanisms.

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

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.

    Full Text Available A anemia ferropriva, talassemia menor e anemia de doença crônica são as anemias microcíticas e hipocrômicas mais comuns em nosso meio. 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. Differential diagnosis of these anemias is of great clinical importance however, frequently, it is complex due to coexistence of diseases, as well as being time consuming and expensive. 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.

However, the importance of anemia in RA patients is frequently underestimated. The etiology of anemia in RA is complex. Anemia of inflammation (AI) and iron deficiency anemia, alone or in combination are the most frequent forms of anemia in RA. Changes in iron metabolism are the leading causes of anemia in RA patients and mainly induced by the altered synthesis and function of hepcidin and ferroportin. Hepcidin, a peptide produced in the liver and immunocompetent cells, impairs the expression of ferroportin on iron-secreting cells, thus reducing iron bioavailability. The typical changes of iron metabolism and hepcidin synthesis in RA are induced by proinflammatory cytokines, primarily interleukin-6. Hence, the treatment of RA with cytokine antagonists has significant therapeutic implications on anemia in the context of inflammation and impaired iron metabolism.

    Full Text Available Aplastic anemia is a rare heterogeneous disorder of hematopoietic stem cells causing pancytopenia and marrow hypoplasia with the depletion of all types of blood cells. This results in anemia, neutropenia and thrombocytopenia, which pose a challenge to both surgical and anesthetic management of such cases. We report a child with aplastic anemia who sustained traumatic ulcer on the arm and underwent split-thickness skin grafting under general anesthesia. There are only two case reports on anesthetic considerations in aplastic anemia patients in the literature. The anesthetic management is challenging because of the rarity of the disease, associated pancytopenia and immunosuppression.

    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. Resultados: Las concentraciones medias de selenio en plasma fueron de 76,6 ± 17,3 μg/L (87,3 ± 17,4 μg/L en los hombres, y de 67,3 ± 10,7 μg/L para las mujeres, mientras que los valores eritrocitarios de selenio de la poblacion total del estudio fue de 104,6 μg/L (107,9 ± 26,1 μg/L en hombres y 101,7 ± 21,7 μg/L en mujeres.

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

    Full Text Available La vitamina A desempeña un papel fundamental en el desarrollo de los tejidos y órganos gracias a su capacidad de promover la diferenciación celular y regular la apoptosis. Específicamente en el sistema inmune, esta vitamina tiene efectos muy importantes sobre componentes específicos tanto de la respuesta inmune innata como de la adaptativa. En la inmunidad innata, el ácido retinoico (AR participa en la regeneración de las mucosas y epitelios, promueve la diferenciación de células como los neutrófilos y eosinófilos y potencia la fagocitosis. Además, ayuda a la migración de las diferentes células inmunes promoviendo la producción de metaloproteinasas de matriz extracelular. Aunque sus efectos en las células NK son más controversiales, se ha encontrado que el número y la función lítica de estas células disminuyen cuando hay deficiencia de vitamina A (DVA. Por otra parte, el AR influencia el desarrollo de la inmunidad adaptativa alterando el perfil de producción de citoquinas por parte de las células presentadoras de antígeno, lo que influye en la diferenciación de los linfocitos T ayudadores. En general, se ha observado que el AR amplifica la proliferación de las células T y potencia el desarrollo de células plasmáticas a partir de los linfocitos B maduros. Todos estos efectos tienen repercusiones importantes en la adecuada defensa contra las infecciones, especialmente en la infancia en la cual la DVA es un problema importante de salud pública, no solo en Colombia sino también en aproximadamente otros 60 países.

  11. Unexplained Aspects of Anemia of Inflammation

    Directory of Open Access Journals (Sweden)

    Elizabeth A. Price

    2010-01-01

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

Porém, apesar de percentual modesto, indícios epidemiológicos apontam no sentido inverso, ou seja, indicam a crescente e grave ocorrência de anemia em diferentes regiões do mundo, inclusive no Brasil. 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.

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

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

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

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

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

    Introdução: A anemia hemolítica pode estar associada a múltiplas etiologias, nomeadamente a tóxicos, como os metais, sendo esta uma causa rara.Caso Clínico: Homem de 55 anos de idade, sujeito a artroplastia total da anca direita (prótese não cimentada com articulação cerâmica-cerâmica, cujo componente acetabular era constituído por uma cúpula metálica composta por uma liga de titânio, vanádio e alumínio na qual encaixava um insert cerâmico). Cerca de quatro anos após esta intervenção cirúrgica referia ruídos na prótese com os movimentos. Foi sujeito a revisão cirúrgica tendo-se constatado a presença de líquido espesso intracapsular de cor escura, fractura do insert acetabular cerâmico e sinais de desgaste da cúpula metálica acetabular. Procedeu-se a lavagem abundante e substituição do insert cerâmico fracturado por um insert de polietileno. Dois meses depois recorreu ao Serviço de Urgência por degradação do estado geral, flutuação na anca direita e icterícia muco-cutânea. Analiticamente evidenciava valores compatíveis com anemia hemolítica autoimune. Foi feita punção articular com saída de abundante líquido metalótico. A tomografia computorizada revelou extensa colecção heterogénea quística intrapélvica com múltiplos fragmentos de prótese no seu interior, sugestivos de metalose. A anemia hemolítica foi interpretada como consequência da toxicidade das partículas e iões metálicos oriundos do desgaste da prótese. Iniciou corticoterapia em altas doses e posteriormente quando houve condições procedeu-se à substituição de todos os componentes da prótese e drenagem do material acumulado intra-pélvico.Discussão: Após a fractura do insert cerâmico a cabeça cerâmica passou a articular directamente com o componente acetabular metálico, originando os ruídos e desgaste com libertação de partículas e iões.

    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

    Rosse, Wendell F; Hillmen, Peter; Schreiber, Alan D

    2004-01-01

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

  16. [A simple algorithm for anemia].

    Science.gov (United States)

    Egyed, Miklós

    2014-03-09

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

    1998-01-01

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

    Berentsen, Sigbjørn

    2015-09-01

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

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

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

Una revisión actual de la literatura identifica solamente 19 pacientes que han logrado el embarazo. Presentamos el caso de una paciente de 16 años portadora de anemia de Fanconi, la cual presenta un embarazo de 30 semanas complicado por un cuadro de preeclampsia severa asociada a trombocitopenia severa, hemorragia intraparenquimatosa, convulsiones y neumonía.

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

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

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

  9. Mitochondrial iron metabolism and sideroblastic anemia.

    Science.gov (United States)

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

    2009-01-01

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

    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.

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. PMID:26309349

    Full Text Available La era actual se caracteriza por una búsqueda de la identidad del hombre, donde el pivote del cambio organizacional es el individuo; cambiar en este entorno depende, en gran medida, de los valores que imperen en la cultura de la organización. Este trabajo documental intenta identificar aquellos valores, condición sine-qua-non, para el logro de los objetivos de cambio y analizarlos a fin de determinar sus indicadores, con el objeto de presentar una herramienta a las organizaciones que les facilite adaptarse a los nuevos tiempos. Se encontró que los valores: Delegación, Comunicación, Colaboración, Participación y Aprendizaje, son esenciales en los cambios integrales de esta era. Se determinaron 20 indicadores de su presencia. Se concluye que con esta información cada ente puede elaborar instrumentos que le permitan saber si los valores requeridos están presentes y en caso contrario tomar decisiones que alineen a la organización alrededor de los valores humanistas planteados, incrementando así las posibilidades de éxito en el proceso de cambio y por ende, las posibilidades de supervivencia en esta nueva época.

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

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

    2005-10-01

    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.

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

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

    Full Text Available A anemia é considerada um problema de saúde pública em escala mundial e é o distúrbio hematológico de maior prevalência que acomete a população idosa. O objetivo deste trabalho foi estimar a prevalência e características da anemia em idosos do Programa de Saúde da Família de Camaragibe, PE. 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.

    2007-01-01

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

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

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

  17. Hereditary sideroblastic anemias: pathophysiology, diagnosis, and treatment.

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

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

    Anemia is one of the most common public health problems in developing countries like Nepal. This study was done to find the prevalence of anemia among the children aged 4-13 years in eastern Nepal. A cross-sectional study was conducted in 2012 in four districts (Morang, Udayapur, Bhojpur and Ilam) of eastern Nepal to find the prevalence of anemia among the school children of eastern Nepal. Children aged 4-13 years were selected randomly from different schools of above districts and 618 venous blood samples were collected. Hemoglobin level was estimated by using cyanmethemoglobin method. The mean hemoglobin level was 12.2 ± 1.82 gm/dl. About 37.9% (n = 234) children were found anemic. Anemia prevalence was 42.4% (n = 78), 31.6% (n = 60), 45.3% (n = 48) and 34.8% (n = 48) among school children of Morang, Udayapur, Bhojpur and Ilam district, respectively. The study finds anemia as a significant health problem among the school children of eastern Nepal.

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

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

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

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

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

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

    Full Text Available OBJETIVO: Avaliar a prevalência de anemia, deficiência de ferro e anemia por deficiência de ferro em uma coorte de crianças. MÉTODOS: Estudo de coorte aninhado a um ensaio de campo randomizado. As crianças foram selecionadas ao nascimento na maternidade do único hospital público da cidade de São Leopoldo (RS, Brasil. O presente estudo avaliou o estado nutricional de ferro (hemoglobina e ferritina sérica quando essas crianças apresentavam idade de 12-16 meses e, posteriormente, na idade de 3-4 anos. A anemia foi definida pela concentração de hemoglobina < 11,0 g/dL; a deficiência de ferro, por ferritina sérica < 15,0 µg/L; e a anemia por deficiência de ferro, pela presença de concentrações de hemoglobina < 11,0 g/dL com deficiência de ferro. RESULTADOS: Na idade de 12-16 meses, a prevalência geral de anemia, deficiência de ferro e anemia por deficiência de ferro foi de 63,7, 90,3 e 58,8%, respectivamente. Esses valores, para a faixa etária de 3-4 anos, foram de 38,1, 16,1 e 7,4%, respectivamente. Na idade de 12-16 meses, 95% dos casos de anemia foram associados à deficência de ferro, e na idade de 3-4 anos, apenas 19,3% dos casos. CONCLUSÕES: Observou-se que a deficiência de ferro foi a principal causa da anemia no segundo ano de vida, porém não na idade de 3-4 anos. Assim, enfatiza-se que a anemia em crianças de idade pré-escolar pode ter outras etiologias e merece avaliações cuidadosas.

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

    Full Text Available La anemia de Fanconi es una falla clásica de la médula ósea, la cual tiene una incidencia de menos de 1 en 100,000 nacidos vivos. Hasta ahora, las pacientes femeninas normalmente no alcanzaban la edad reproductiva y mucho menos lograban el embarazo. Una revisión actual de la literatura identifica solamente 19 pacientes que han logrado el embarazo. Presentamos el caso de una paciente de 16 años portadora de anemia de Fanconi, la cual presenta un embarazo de 30 semanas complicado por un cuadro de preeclampsia severa asociada a trombocitopenia severa, hemorragia intraparenquimatosa, convulsiones y neumonía. El manejo obstétrico de estas pacientes es muy complejo. El tratamiento debe ser individualizado a las necesidades de cada paciente hasta que la literatura agrupe más casos y se ofrezcan normas de manejo.

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

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

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

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

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

    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.

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

    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 OBJECTIVE: Post-transplant anemia is a common complication in renal allograft recipients. The most common causes are impaired graft function, immunosuppressive drugs, and infections. The aim of our study was to further investigate the prevalence of anemia before and after renal transplantation in renal allograft recipients in Turkey. MATERIAL and METHODS: We assessed 464 patients who received a kidney transplant between the years 2010 and 2012. The prevalence of anemia was evaluated before transplantation and at the 3 rd and at 6th months after transplantation. Our study is a retrospective study. RESULTS: The prevalence of anemia at the 6th month after the transplant surgery was 28.8%. The percentage of the patients who did not have anemia prior to the transplant surgery, and who developed anemia after the transplantation was 24.4%. CONCLUSION: Our findings are similar to those found in the literature, and show that anemia is a very common entity after renal transplantation.

The purpose of this study was to elucidate the risk factors of neonatal anemia in placenta previa.Methods: The study was conducted on 158 placenta previa patients at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 through December 2009. The subjects were divided in to 2 groups: 47 placenta previa patients with neonatal anemia, and 113 placenta previa patients without neonatal anemia. The subjects' characteristics were compared. Logistic regression was used to control for confounding factors.Results: Anterior placental location (OR 2.48; 95% CI: 1.20-5.11 was an independent risk factor of neonatal anemia after controlling for potential confounders.Conclusion: To manage neonatal anemia in placenta previa patients, obstetricians should do their best to detect placental location. Pediatricians should consider the high possibility of neonatal anemia in cases involving anterior placental location.

    1989-12-01

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

    Obesity-induced chronic inflammation leads to activation of the immune system that causes alterations of iron homeostasis including hypoferraemia, iron-restricted erythropoiesis, and finally mild-to-moderate anaemia. Thus, preoperative anaemia and iron deficiency are common among obese patients scheduled for bariatric surgery (BS). Assessment of patients should include a complete haematological and biochemical laboratory work-up, including measurement of iron stores, vitamin B12 and folate. I...

    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.

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

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

    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

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

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

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

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

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

    Full Text Available OBJETIVO: Verificar a prevalência de anemia em crianças do município de Campinas, levando-se em consideração a introdução de alimentos complementares. MÉTODOS: Estudo transversal realizado com 354 crianças de seis a 12 meses de idade, sorteadas do Sistema de Informações de Nascidos Vivos da cidade de Campinas. Profissionais da área da saúde devidamente treinados realizaram entrevista domiciliar com as mães dos lactentes, as quais responderam a um questionário contendo dados sobre a introdução de alimentos e condições socioeconômicas. Ao final, coletou-se sangue capilar do lactente, para dosagem de hemoglobina com o Hemocue®. Foram consideradas anêmicas as crianças com concentrações de hemoglobina inferiores a 11g/dL. Os dados foram avaliados por análise de sobrevida para verificar a associação da introdução alimentar com a anemia. RESULTADOS: Dos lactentes estudados, 66,5% apresentaram níveis de hemoglobina OBJECTIVE: To verify the prevalence of anemia associated with the introduction of complementary food in children less than two years old in the city of Campinas, São Paulo, Brazil. METHODS: A cross-sectional survey was performed in 354 children between 6 and 12 months of age which were registered in the Live Births Information System from Campinas area. Health professionals interviewed the mothers, who answered a questionnaire about food introduction and socioeconomic status. Capillary blood was collected and the hemoglobin level was determined by Hemocue®. Anemia was diagnosed if hemoglobin level was below 11g/dL. Survival analysis was performed to determine the influence of complementary food introduction on anemia. RESULTS: 66.5% of the children had hemoglobin levels lower than 11g/dl. Anemia was associated to early introduction of the family diet (p=0.036, bread (p=0.012, yogurt (p=0.006, soft drinks (p=0.005, candies (p=0.005 and snacks (p=0.013. CONCLUSIONS: Inadequate complementary food introduction is

    Full Text Available A anemia ferropriva é conhecida como uma das principais deficiências nutricionais em todo o mundo e sua ocorrência pode ser observada em diversas populações. Alguns grupos populacionais ainda apresentam altas prevalências de anemia ferropriva, comprometendo diversas funções do organismo. Dentre esses grupos de risco, podem ser citadas as gestantes, que merecem especial atenção devido à sua vulnerabilidade à carência e ao aumento significativo de suas necessidades, que não são acompanhados por aumento suficiente no consumo ou na absorção de ferro. Este artigo analisa dados de artigos publicados nos últimos 40 anos nas línguas inglesa, espanhola ou portuguesa nos bancos de dados Lilacs e Medline sobre prevalência de anemia ferropriva na gestação. Em todas as pesquisas verificadas, a prevalência de anemia ferropriva na gestação apresenta valores elevados, o que caracteriza essa situação como um problema de saúde pública para o Brasil, mesmo com as políticas nacionais atuais de combate à deficiência.Iron-deficiency anemia is known as one of the main nutritional deficiencies around the world and its occurrence can be observed in many populations. Some groups still present a high prevalence of iron-deficiency anemia, compromising many body functions. Pregnant women are among the groups at risk given their vulnerability to deficiencies and the significant increase in their requirements, which are not accompanied by a sufficiently higher iron intake or absorption. This paper analyzes data from articles published in the last 40 years in English, Spanish or Portuguese found in the Lilacs and Medline databases about the prevalence of iron-deficiency anemia during pregnancy. Every paper found reports a high prevalence of anemia in pregnant women, characterizing this situation as a public health problem in Brazil, despite current Brazilian policies to fight iron deficiency.

    Full Text Available A anemia por carência de ferro representa a deficiência nutricional de maior prevalência em todo o mundo. A mulher e a criança são os grupos biológicos mais vulneráveis. Embora seja um dos procedimentos terapêuticos mais antigos da prática médica, o tratamento das anemias carenciais não está devidamente consolidado na rotina dos serviços de saúde. Em conseqüência, a eficácia do tratamento, os esquemas de tratamento, as recomendações posológicas, a adesão das pacientes e os critérios de acompanhamento são pontos cruciais na avaliação das propostas de intervenção a serem implementadas.The iron-deficiency anemia represents the nutritional disorder of higher prevalence in the whole world. The woman and child are the groups more vulnerable. Although the treatment of the anemia is one of the oldest therapeutic, this procedure is not entirely established in the routine of the health services. Therefore, the effectiveness of the treatments, the different schemes, the posology recommendations, the adhesion of the patients to the treatment and the follow-up criteria are essential points in the evaluation of proposed interventions.

    Full Text Available The author analyzes the scientific and philosophical debates in postrevolutionary France on the role played by the process of socialization in human intellectual development. In addition, he discusses the way in which the controversy on wild children —specifically on the case of Víctor de l'Aveyron—, constituted a sort of "foundation myth" for such disciplines as paedopsychiatry or psychopedagogy. The case was used as justification of the "origins" of these disciplines in the attempts to institutionalize them.El presente trabajo analiza los debates científicos y filosóficos suscitados en la Francia postrevolucionaria sobre el papel jugado, en el desarrollo intelectual del ser humano, por el proceso de socialización. Asimismo, se estudia de qué manera el debate sobre los niños selváticos y, concretamente, el caso de Víctor de l'Aveyron, constituyó una especie de "mito fundacional" de disciplinas como la paidopsiquiatría o la psicopedagogía, al ser utilizado como justificación de los "orígenes" en los intentos de institucionalización de las mismas.

    Full Text Available Postmenopausal vegetarian female presented with short febrile illness associated with generalized weakness Clinical and investigative findings evidenced megaloblastic anemia Since none of investigations could pinpoint the cause for pyrexia and patient did not respond to empirical antibiotic and conservative antimalarial therapy, megaloblastic anemia itself was suspected to be cause for febrile episode Patient was treated with parenteral B12 and oral folic acid for megaloblastic anemia and she responded to it and became afebrile within 72 hours. Subsequently megaloblastic anemia was correlated to be cause of febrile illness.

    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.
