ABSTRACT

La infección por parvovirus B19 humano, es la causa de la mayor parte de los casos de crisis aplásica transitoria que aparecen de forma brusca en pacientes con enfermedades hemolíticas crónicas, como es el caso de la drepanocitosis. Por otra parte, se han descrito unos pocos casos de infección aguda, por parvovirus B19 humano como causa de anemia hemolítica autoinmune, por medio de la formación de anticuerpos dirigidos contra los glóbulos rojos. La asociación entre drepanocitosis y anemias hemolíticas autoinmunes es poco frecuente. Se reporta un caso poco usual de una paciente adulta, con antecedentes de hemoglobinopatía S/C que presentó una crisis aplásica y posteriormente apareció una anemia hemolítica autoinmune diagnosticada en el Instituto de Hematología e Inmunología. Se trató con dosis inmunosupresoras de esteroide, con lo que se alcanzó la remisión de la anemia hemolítica autoinmune(AU)


Infection with human B19 parvovirus is the cause of most cases of transient aplastic crisis that appear in patients with chronic hemolytic diseases, as in the case of sickle cell disease. On the other hand, a few cases of acute infection by human parvovirus B19 have been described as a cause of autoimmune hemolytic anemia, through the formation of antibodies directed against red blood cells. The association between sickle cell disease and autoimmune hemolytic anemia is rare. We report an unusual case of an adult patient, with a history of S C hemoglobinopathy who presented an aplastic crisis and subsequently an autoimmune hemolytic anemia diagnosed at the Institute of Hematology and Immunology, treated with high steroids doses, reaching the remission of autoimmune hemolytic anemia and constitutes the first report in Cuba(AU)

ABSTRACT

The term autoimmune cytopenias is referred to a heterogeneous group of diseases characterized by a reduced peripheral blood cell counts in one or more cellular series, because an immunological disorder. The first line therapy is steroids, followed by splenectomy or immunesupressant therapy in non-responders. Rituximab is an anti CD20 monoclonal antibody used as a third line in refractory patients or as an alternative to splenectomy. We present a retrospective study of nine patients with autoimmune cytopenias treated in a public hospital setting with rituximab. Five patients with the diagnosis of inmune thrombocytopenic purpura received it, all of them achieved hematological response (4 complete and one partial). The median time to the best response was 6 weeks, staying in this category after 6 months of follow up. Four patients with autoimmune hemolytic anemia received rituximab, three of them achieving partial response and one was lost from follow up. No severe adverse effects related to rituximab were registered.

ABSTRACT

Resumo Relatar um caso de paciente com Retinopatia vaso-oclusiva por Lúpus Eritematoso Sistêmico (LES) associado à Síndrome do Anticorpo Antifosfolipídeo (SAF), que se iniciou com um quadro de anemia hemolítica autoimune acompanhado por baixa visual súbita monocular. Poucos casos foram descritos na literatura nacional e mundial em que o LES se manifeste primeiramente com alterações oculares. O screening dos Anticorpos antifosfolípideos (APAs) é de suma importância para pacientes com retinopatia lúpica para que seja instituída a terapia imediata com anticoagulantes como forma de prevenir a trombose vascular, o que piora o prognóstico visual.


Abstract To report the case of a patient with vaso-occlusive retinopathy due to systemic lupus erythematosus (SLE) associated with antiphospholipid antibody syndrome (APAS), which started with signs and symptoms of autoimune hemolytic anemia accompanied by sudden monocular visual loss. Few cases of SLE manifestation primarily involving ocular changes have been reported in the Brazilian and international literature. Screening for antiphospholipid antibodies is of the greatest importance for patients with lupus retinopathy, so that immediate therapy with anticoagulants may be instituted in order to prevent vascular thrombosis, which worsens the visual prognosis.

ABSTRACT

Introducción: la anemia hemolítica autoinmune (AHAI) constituye un cuadro clínico heterogéneo caracterizado por la existencia de autoanticuerpos contra antígenos presentes en la membrana de los eritrocitos del paciente que provocan el acortamiento de su vida media. Objetivo: conocer las características clínicas y de laboratorio de las anemias hemolíticas autoinmunes diagnosticadas en el centro. Métodos: se realizó un estudio descriptivo, retrospectivo y de cohorte que incluyó 15 pacientes con el diagnóstico de AHAI en el Hospital Militar Central Dr. Carlos J. Finlay, entre enero de 2011 y diciembre de 2013. Resultados: el rango de edad de los pacientes estudiados fue de 34 a 75 años (mediana de 59 años); de ellos, 8 fueron del sexo femenino y 7 del masculino. El 87 por ciento presentó una AHAI idiopática y el 13 por ciento secundaria. Las secundarias se asociaron con lupus eritematoso sistémico (n = 1) y leucemia linfoide crónica de estirpe B (n = 1). Existió anemia grave de comienzo súbito en el 40 por ciento, e insidioso en el 60 por ciento, íctero en el 73 por ciento, esplenomegalia en el 13 por ciento y dolores articulares difusos en el 20 por ciento de los pacientes. La prueba de Coombs directa resultó positiva en 14 pacientes. Al mes de tratamiento con esteroides, el 33 por ciento presentó una respuesta completa, el 40 por ciento una respuesta parcial y el 27 por ciento no respondió. Conclusiones: este estudio muestra los hallazgos clínicos y de laboratorio de una pequeña serie de casos adultos con AHAI. La etiología primaria o idiopática fue la más frecuente pero se requiere evolucionar en el tiempo a los pacientes ya que esta entidad puede preceder la aparición de hemopatías malignas o enfermedades del colágeno(AU)


Introduction: autoimmune hemolytic anemia (AIHA) is a heterogeneous clinical picture characterized by the presence of autoantibodies against antigens present on the membrane of the patient's erythrocytes causing shortening of the average life. Objective: To determine the clinical and laboratory autoimmune hemolytic anemias diagnosed in our hospital. Methods: adescriptive, retrospective cohort study involving 15 patients with the diagnosis of AIHA was carried out at Dr. Carlos J. Finlay Central Military Hospital, between January, 2011 and December, 2013. Results: the mean age of the patients was 34 - 75 years (median 59 years), 8 were female and 7 male; 87 percent had idiopathic AIHA and 13 percent secondary AIHA. Secondary hemolytic anemias were associated with systemic lupus erythematosus SLE (n = 1) and B-cell chronic (n = 1) lymphoid leukemia. There was severe anemia (median Hb. 69 g / L) of sudden onset in 40 percent, insidious in 60 percent, jaundice in 73 percent, splenomegaly in 13 percent and diffuse joint pain in 20 percent of patients. The direct Coombs test was positive in 14 patients. After a month of steroid treatment, 33 percent had a complete response, 40 percent partial response and 27 percent did not respond. Conclusions: this study shows the clinical and laboratory characteristics of a small number of adults cases with AIHA findings. Primary or idiopathic etiology was the most frequent but evolve evolving patients over time it is required requires patients and that as this entity may precede the onset of hematological malignancies or collagen diseases(AU)

ABSTRACT

El tratamiento de las anemias hemolíticas autoinmunes (AHAI) se basa en la evaluación clínica individual, las características inmunoquímicas de los anticuerpos que las generan y su carácter idiopático o secundario. El tratamiento de las AHAI primarias varía de acuerdo con su clasificación inmunohematológica; en las generadas por anticuerpos calientes el tratamiento de primera línea son los esteroides. Después de la remisión inicial, se disminuye lentamente la dosis hasta alcanzar la de mantenimiento requerida; en los pacientes corticorresistentes y corticodependientes suele emplearse la esplenectomía y el Rituximab (anticuerpo monoclonal anti CD 20), y en menor medida, algunas drogas inmunosupresoras como la azatioprina o la ciclofosfamida. Los pacientes con AHAI por aglutininas frías son refractarios al tratamiento con esteroides y la esplenectomía; los que presentan anemia estable poco sintomática suelen requerir como único tratamiento evitar la exposición al frío, y de requerir tratamiento adicional, el más efectivo es el Rituximab, aunque también se pueden emplear inmunosupresores como la ciclofosfamida y el clorambucil. La hemoglobinuria paroxística a frío generalmente no requiere tratamiento. Las AHAI mixtas se tratan de forma similar a las calientes, mientras que las secundarias a drogas suelen responder satisfactoriamente a la suspensión de la droga y al tratamiento con esteroides. En todos los tipos de AHAI deben evitarse las transfusiones de sangre, excepto cuando hay peligro para la vida, en cuyos casos deben administrarse pequeños volúmenes de concentrados de eritrocitos, en infusión lenta y a 37(0) C a los pacientes con anticuerpos fríos


The treatment of autoimmune hemolytic anemias (AIHA) is based on the individual clinical evaluation, immunochemical characteristics of the involved antibodies and the absence or presence of an underlying condition. The treatment of AIHAs varies according to its immunohematological classification. The steroids are the first line therapy for AIHA due to warm antibodies (wAIHA). After the initial remission, the doses should be reduced slowly, until the required maintenance level is reached; steroid-dependent or steroid resistant patients often require splenectomy or treatment with Rituximab (anti CD20 monoclonal antibody) and with less frequency, immunosuppressive drugs as azathioprine or cyclophosphamide. Patients with cold AIHA agglutinins (cAHAI) are resistant to steroids and splenectomy; patients with asymptomatic or stable anemia do not require treatment. Rituximab is the most effective treatment for symptomatic cases, although immunosuppressants such as cyclophosphamide and chlorambucil could be used. Paroxysmal cold hemoglobinuria do not usually require treatment. Mixed type AIHAs may be treated similarly to those with wAIHA. Drug induced AIHAs usually respond to discontinuing the offending drug and steroids treatment. Transfusion should be avoided in AIHAs, except in life threatening situations; if it is required, small volumes of erytrhocyte concentrates should be administered, slowly, in cAIHA; the blood should be prewarmed at 37(0) C

ABSTRACT

La asociación de anemia hemolítica autoinmune (AHAI) con hepatitis de células gigantes (HCG) es un transtorno raro en la infancia. Son pocos los casos reportados y la gran mayoría fallecen a pesar de transplante hepático. La AHAI usualmente precede el desarrollo de la afección hepática. El diagnóstico temprano de esta asociación y el inicio de terapia inmunosupresora previene la progresión de la enfermedad...

ABSTRACT

A anemia hemolítica autoimune (AHAI) é uma doença na qual são produzidos anticorpos diretamente contra as glicoproteínas adsorvidas na superfície da membrana dos eritrócitos. Algumas medicações e outras associações têm sido implicadas. Descrevemos e discutimos um caso de livedo reticular associado à AHAI tratado com transplante de células-tronco de sangue periférico (TCTSP) e que entrou em total remissão por 10 anos. Após esse período, a paciente apresentou recaída, foi tratada com anticorpo anti-CD20 (rituximabe), e atualmente encontra-se em total remissão. O papel do TCTSP e o uso de rituximabe no tratamento de AHAI serão discutidos neste relato de caso.


Autoimmune hemolytic anemia (AIHA) is a disease where patients produce antibodies against erythrocytes directed towards membrane glycoproteins adsorbed onto the erythrocyte surface. Drugs and other associations have been implicated. It is described and discussed a case of livedo reticularis associated with AIHA treated with peripheral blood stem cell transplantation (PBSCT) that went into full remission for 10 years. After that period the patient relapsed and was treated with antibody anti-CD20, rituximab, and is now in full remission. The role of PBSCT and rituximab in the treatment of AIHA will be discussed.

ABSTRACT

A 44-year-old woman was found to have elevated aminotransferases, twice the upper limit of normal. Liver biopsy demonstrated a mixed inflammatory process suggestive of both primary biliary cirrhosis and autoimmune hepatitis (AIH). Prednisone and azathioprine were started, with normalization of aminotransferases. Six months later, she returned with worsening pruritus and re-evaluation demonstrated probable reactivation of AIH with acute elevation of liver injury tests. Repeat liver biopsy was suggestive of a flare of AIH which did not respond to prednisone, azathioprine, or mycophenolate mofetil. One month later the patient was hospitalized for sudden onset of anemia and thrombocytopenia, suggestive of autoimmune hemolytic anemia and idiopathic thrombocytopenic purpura consistent with Evans syndrome. Rituximab was initiated and mycophenolate mofetil discontinued. After one infusion of rituximab, liver injury tests significantly improved. Within four weeks of rituximab infusion (4 doses) the patient's Evans syndrome completely resolved with normal hemoglobin and platelet levels; aminotransferases also significantly improved to less than twice the upper limit of normal.

ABSTRACT

La anemia hemolítica autoinmune es la manifestación inmunológica más frecuente en la leucemia linfocítica crónica (LLC) y se presenta entre el 10-20 por ciento de los casos. Su prevalencia está relacionada con el estadio y progresión de esta hemopatía, así como con el estado mutacional de los genes de la región variable de la cadena pesada de las inmunoglobulinas. Los corticosteroides constituyen la primera línea de tratamiento en esta anemia hemolítica autoinmune, pero solo la tercera parte de los pacientes responden y logran una remisión duradera, mientras que otros requieren tratamientos de mantenimiento o alternativos. Recientemente, se ha demostrado la efectividad del rituximab en el tratamiento de la anemia hemolítica autoinmune refractaria a la terapéutica esteroidea, incluso en los pacientes asociados con LLC. Se expone nuestra experiencia con el esquema R-COP (rituximab, ciclofosfamida, vincristina, prednisona) en el tratamiento de un paciente con LLC en recaída y anemia hemolítica autoinmune, que después de 20 meses de concluido este esquema se mantiene en remisión completa.


The autoimmune hemolytic anemia is the more frequent immunologic manifestation in chronic lymphocytic leukemia (CLL) and it is present between 10-20 percent of cases. Its prevalence is related to stage and progression of this blood disease, as well as to mutation state of genes from the heavy chain variable region of immunoglobulins. The corticosteroids are the first line treatment in this autoimmune hemolytic anemia, but only the third part of patients responds and achieves a lasting remission, whereas others require support treatment or of alternative type. Recently, it has been shown the effectiveness of Rituximab in treatment of refractory autoimmune hemolytic anemia that after 20months of ended this scheme it is maintained in complete remission.

ABSTRACT

OBJECTIVE: To study the clinico-hematological profile and treatment outcome in children suffering from auto immune hemolytic anemia (AIHA). METHODS: Twelve children were diagnosed with auto immune hemolytic anemia over a period of four years. Direct antiglobulin test was positive in all the cases. Other causes of hemolytic anemia like thalassemia syndromes, hereditary spherocytosis, G6PD deficiency were excluded by appropriate tests. The children were followed up for 6 months to 4 years. RESULTS: The age ranged from 7 mth to 9 yr with a mean age of 4.51 yr. All patients had pallor as the presenting complaint followed by splenomegaly (83.3%), jaundice (66.7%), fever (50%) and bleeding manifestations (16.7%). 9 patients had primary disease and 3 had secondary disease. Tubercular infection was seen in 2 patients with secondary disease. Jaundice was seen equally in both the groups. Oral prednisolone produced remission in 83.3% cases. 4 patients (3 in primary and one in secondary group) had relapse after initial response. All responded to a second course of steroids but had subsequent relapses and developed a chronic course. CONCLUSION: Autoimmune hemolytic anemia is an uncommon cause of hemolytic anemia in children. Tubercular infection is an underlying pathology in cases of secondary autoimmune hemolytic anemia. Although oral steroids induce remission in most of the cases, relapses are common.

ABSTRACT

Se estudiaron 18 pacientes: 15 adultos y 3 niños, con Anemia Hemolítica y sospecha de etiología inmune donde se observó una respuesta favorable al tratamiento con Prednisona. Todos los pacientes habían mostrado resultados negativos en la prueba de antiglobulina directa e indirecta (Coombs). A las muestras de sangre se les realizó la Técnica de Polibreno Directa (TPD), la Detección de Autoanticuerpos en el Eluato de los Hematíes en la Técnica de Microplacas (Mp), así como también la Cuantificación de Autoanticuerpos asociados a los hematíes a través de un ELlSA. Los pacientes investigados representaron el 13.3 por ciento del total de casos de AHAI diagnosticados en el período de estudio. La TPD detectó los anticuerpos en 5 casos (28 por ciento), la Mp resultó positiva en 11 pacientes (61 por ciento) y el ELlSA demostró autoanticuerpos en todos los pacientes. El ELlSA reveló la presencia de autoanticuerpos IgG en 17 casos (94,4 por ciento), de IgA en 8 pacientes (44,4 por ciento) y de Ig M en un caso (5,5 por ciento). En 10 pacientes (55,5 por ciento) la cuantificación de autoanticuerpos Ig G se comportó en una rango de 200 a 460 moléculas por hematíe y en el resto se obtuvieron valores superiores a 900 moléculas por hematíe. Los resultados muestran que el ELlSA aplicado es particularmente útil para la detección y cuantificación de autoanticuerpos en los hematíes de los pacientes con AHAI con prueba de Coombs negativa y nos provee de un procedimiento para el diagnóstico inmunohematológico de esta identidad.

ABSTRACT

Mixed type Evans syndrome is a very rare hematologic disease. Although mixed type Evans syndrome may initially respond well to steroids, this disease usually runs a chronic course with intermittent exacerbations. We describe here a 46-yr-old female with the steroid-refractory, mixed type Evans syndrome, and she had a prompt response to rituximab. She was diagnosed as having the mixed type Evans syndrome with the clinical features of symptomatic anemia, jaundice and thrombocytopenia. Prednisone therapy was commenced and her hemoglobin and platelet level returned to the normal. However, after 15 weeks, she relapsed with hemolytic anemia and thrombocytopenia. We started rituximab at the dose of 375 mg/m2 once weekly for a total of 4 doses, which was well-tolerated and this induced the normalization of hemoglobin, bilirubin and lactic dehydrogenase, and there was also a significant increase of the platelet count.

ABSTRACT

El síndrome de aglutininas frías es una forma de anemia hemolítica autoinmune poco común. Fue descrito por primera vez hace más de un siglo. En ésta entidad, la lisis de los glóbulos rojos es la medida para la activación del complemento, pero mayormente interviene la fagocitosis por el sistema retículo endotelial. Esta hemólisis ocurre a temperaturas inferiores a 37ºC. La presentación puede ser idiopática o secundaria y su tratamiento está relacionado con la causa de fondo. A continuación se presenta el caso de una paciente de 80 años con anemia hemolítica y síntomas respiratorios asociados al uso ambulatorio de antibióticos, cuyos resultados de laboratorio mostraron títulos altos de aglutininas frías. Descriptores: aglutininas frías, anemia hemolítica autoinmune, anticuerpos fríos, síndrome aglutininas frías.
