ABSTRACT

La telangiectasia hemorrágica hereditaria (THH) es una displasia vascular multisistémica, de herencia autosómica dominante, caracterizada por el desarrollo de telangiectasias mucocutáneas y malformaciones arteriovenosas viscerales. El diagnóstico se realiza mediante los criterios de Curasao publicados en el año 2000 y su manejo requiere de un equipo multidisciplinario donde el rol del otorrinolaringólogo(a) es fundamental, puesto que la epistaxis se presenta en un 90%-95% de los pacientes siendo una de las primeras manifestaciones clínicas de la enfermedad y pudiendo amenazar la vida del paciente. En la literatura se describen múltiples alternativas de tratamiento médico y quirúrgico para la epistaxis, sin existir un tratamiento definitivo para la enfermedad. A continuación, presentaremos el caso de una paciente de 56 años con THH y epistaxis recurrentes severas que, tras no responder al tratamiento médico conservador y múltiples procedimientos quirúrgicos, se realizó el cierre nasal mediante el procedimiento de Young, constituyendo el primer caso reportado en nuestro país.


Hereditary hemorrhagic telangiectasia (HHT) is a multisystemic vascular dysplasia, of autosomal dominant inheritance, characterized by the development of mucocutaneous telangiectasias and visceral arteriovenous malformations. The diagnosis is made using the Curafao criteria published in 2000 and its management requires a multidisciplinary team where the role of the ENTs is fundamental, since epistaxis occurs in 90%-95% of patients, being one of the first clinical manifestations of the disease and may threaten the life of the patient. Multiple medical and surgical treatment alternatives for epistaxis are described in the literature without a definitive treatment for the disease. Here, we present the case of a 56-year-old patient with severe recurrent HHT and epistaxis who, after not responding to the initial conservative and surgical treatments, a nasal closure was performed, using the Young's procedure, constituting the first case reported in our country.

ABSTRACT

La enfermedad de Rendu-Osler-Weber, también conocido como telangiectasia hemorrágica hereditaria, es una enfermedad genética de herencia autosómica dominante con penetrancia incompleta. Afecta por igual a ambos sexos y los síntomas se inician habitualmente entre los 20 y 40 años, pero se considera que la enfermedad está infradiagnosticada. Típicamente las formas clínicas y el debut de esta enfermedad se asocian a los órganos y tejidos que se afectan con mayor frecuencia: telangiectasias en mucosas y en piel, epistaxis, sangramiento gastrointestinal, pulmonar e intracerebral. En contraste, el caso clínico que se presenta se caracteriza porque las primeras manifestaciones clínicas que motivaron la consulta médica fueron crisis de dolores e inflamación ósea en el miembro superior derecho, lo cual es inusual y se inscribe como un elemento de novedad en la enfermedad. Es el objetivo de esta publicación exponer un caso de telangiectasia hemorrágica hereditaria con una forma de presentación atípica en una adolescente. Al alta hospitalaria, la paciente estaba estable, sin complicaciones. Se recomendó seguimiento hospitalario fundamentalmente por la especialidad de Neumología, por ser los pulmones los órganos más afectados(AU)


Rendu-Osler-Weber´s disease, also known as hereditary hemorrhagic telangiectasia, is a genetic disease of autosomal dominant inheritance with incomplete penetrance. It affects both sexes equally and symptoms usually begin between the ages of 20 and 40, but it is considered that the disease is underdiagnosed. Typically, the clinical forms and the onset of this disease are associated with the organs and tissues that are most frequently affected: mucosal and skin telangiectasias, epistaxis, gastrointestinal, pulmonary and intracerebral bleeding. In contrast, the clinical case that is presented is characterized because the first clinical manifestations that motivated the medical consultation were crises of pain and bone inflammation in the right upper limb, which is unusual and is inscribed as an element of novelty in the disease. The objective of this publication is to present a case of hereditary hemorrhagic telangiectasia with an atypical presentation in a female teenager(AU)

ABSTRACT

Osler-Weber-Rendu syndrome is a rare autosomal dominant vascular disorder, characterised by multiple telangiectasesof the skin and mucous membranes with recurrent nasal and gastrointestinal bleedings and arteriovenous malformations of various organ systems. It is also called as hereditary hemorrhagic telangiectasia (HHT). The occurrence of telangiectases in the stomach and small bowel can result in chronic bleeding and anaemia. We report a rare case of 39 year old female with Osler Weber Rendu syndrome associated with portal hypertension. She had recurrent nasal and gastrointestinal bleeding, and presented with complaints of progressive dyspnea NYHA class III. On further evaluation she was found to have portal hypertension, which is a rare association.

ABSTRACT

Resumen ANTECEDENTES: La telangiectasia hemorrágica hereditaria, o síndrome de Rendu-Osler-Weber, es una enfermedad vascular, hereditaria y autosómica caracterizada por telangiectasias mucocutáneas y malformaciones arteriovenosas en el pulmón, el cerebro e hígado. La prevalencia estimada es de 1.5 a 2 personas afectadas por cada 10,000 habitantes. El 90% de los casos se debe a una mutación en el gen endoglina y en el de la cinasa 1 similar al receptor de activina (ACVRL1). En la mujer embarazada, la telangiectasia hemorrágica hereditaria es de alto riesgo, sobre todo durante el segundo y tercer trimestre. OBJETIVO: Reportar un caso de telangiectasia hemorrágica hereditaria y exponer las complicaciones que pueden registrarse durante el embarazo. CASO CLÍNICO: Paciente de 23 años, con antecedente heredofamiliar de madre con diagnóstico de telangiectasia hemorrágica hereditaria (síndrome de Osler-Weber-Rendu) que falleció a los 38 años. Antecedente personal patológico de telangiectasia hemorrágica hereditaria, con diagnóstico a los 12 años luego de múltiples episodios de epistaxis. Recibió tratamiento con transfusiones sanguíneas en múltiples ocasiones y 200 mg de sulfato ferroso cada 24 horas. CONCLUSIÓN: La telangiectasia hemorrágica hereditaria condiciona, en la mujer embarazada, la aparición de complicaciones que pueden poner en riesgo la vida de la madre y el feto. Las mujeres con antecedente conocido deben valorarse antes de la concepción con el propósito de conocer el estado de la enfermedad.


Abstract BACKGROUND: Hereditary hemorrhagic telangiectasia, or Rendu-Osler-Weber syndrome, is an autosomal inherited vascular disease characterized by mucocutaneous telangiectasias and arteriovenous malformations in the lung, brain and liver. The estimated prevalence is 1.5 to 2 affected persons per 10,000 population. Ninety percent of cases are due to a mutation in the endoglin gene and in the activin receptor-like kinase 1 gene (ACVRL1). In pregnant women, hereditary hemorrhagic telangiectasia is high risk, especially during the second and third trimester. OBJECTIVE: To report a case of hereditary hemorrhagic telangiectasia and to expose the complications that can occur during pregnancy. CLINICAL CASE: 23-year-old patient, with hereditary family history of mother diagnosed with hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) who died at 38 years of age. Personal pathological history of hereditary hemorrhagic telangiectasia, diagnosed at the age of 12 years after multiple episodes of epistaxis. She was treated with multiple blood transfusions and 200 mg of ferrous sulfate every 24 hours. CONCLUSION: Hereditary hemorrhagic telangiectasia conditions, in pregnant women, the appearance of complications that can put the life of the mother and fetus at risk. Women with a known history should be evaluated before conception in order to know the status of the disease.

ABSTRACT

A síndrome de Rendu-Osler-Weber, ou telangiectasia hemorrágica hereditária (THH), é uma doença autossômica dominante de penetrância variável que altera a camada muscular e elástica da parede dos vasos sanguíneos, causando neles grande fragilidade e dilatação e tornando-os suscetíveis a sangramentos secundários, a traumatismos e malformações arteriovenosas (MAV) ­ sendo elas as mais comuns no cérebro, nos pulmões e no trato gastrointestinal e hepático. Este relato de caso tem como objetivo realizar uma revisão sobre essa síndrome, bem como a respeito da melhor terapia e do melhor manejo para sangramentos gastrointestinais por angiectasias. Trata-se de uma paciente de 62 anos de idade, com episódio de hematêmese e melena recorrentes, que foi admitida instável hemodinamicamente e com queda importante dos níveis de hemoglobina, necessitando de múltiplas transfusões sanguíneas. Após entrevista clínica, que chamou a atenção para o histórico familiar de quadros similares, epistaxes recorrentes associados ao exame físico e angiectasias gástricas à endoscopia digestiva alta, foi atribuído o diagnóstico de síndrome de Rendu-Osler-Weber. Angiectasias foram erradicadas com terapia endoscópica usando plasma de argônio. A THH é uma doença subdiagnosticada que merece atenção especial por conta do seu risco de causar hemorragias graves com expressão fenotípica mais aflorada com o avançar da idade. Por seu cunho hereditário, faz-se necessário um acompanhamento médico linear com a família para evitar complicações secundárias da doença, bem como para o manejo adequado de suas apresentações.


Osler-Weber-Rendu syndrome or hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease that changes the muscular and elastic layer of the blood vessel wall, making them fragile and more susceptible to bleeding secondary to trauma and arteriovenous malformations (AVM) ­ a condition that commonly affects the brain, lungs, gastrointestinal tract, and liver. This study aims to perform a literature review on this syndrome, as well as on the best treatment and management for gastrointestinal bleeding from angioctasia. To this end, it reports the case of a 62-year-old female patient with recurrent episodes of hematemesis and melena, who was admitted to hospital with hemodynamic instability and low hemoglobin levels, requiring multiple blood transfusions. After clinical interview, which indicated family history of recurrent epistaxis, physical examination, and upper digestive endoscopy showing gastric angiectasias, the patient was diagnosed with Osler-Weber-Rendu syndrome. Angiectasias were treated with endoscopic argon plasma. Considering the risk of severe hemorrhages and its more pronounced phenotypic expression with advancing age, HHT is an underdiagnosed disease that deserves special attention. Due to its hereditary nature, a linear medical follow-up with the family is necessary to avoid secondary complications of the disease, as well as the proper management of its presentations.

Tras entrevista clínica, destacando los antecedentes familiares de patologías similares, epistaxis recurrente, exploración física y angiectasias gástricas a endoscopia digestiva alta, se asignó el diagnóstico de síndrome de Rendu-Osler-Weber. Las angiectasias se erradicaron con terapia endoscópica con plasma de argón. La HHT es una enfermedad infradiagnosticada que merece una atención especial por su riesgo de hemorragias severas, con una expresión fenotípica más pronunciada con el avance de la edad. Además de su carácter hereditario, es necesario un seguimiento médico lineal con la familia para evitar complicaciones secundarias de la enfermedad, así como el adecuado manejo de sus presentaciones.

ABSTRACT

Se describe el caso clínico de una paciente de 84 años que tuvo epistaxis recidivante por padecer enfermedad de Rendu-Osler-Weber. Tuvo antecedentes de diversos tratamientos quirúrgicos que incluyeron el cierre de la fosa nasal izquierda (operación de Young). Por la persistencia de epistaxis izquierda se indicó una angiografía y embolización. Esta última no se hizo porque se diagnosticaron anastomosis entre el sistema carotídeo externo y el interno. Se realizó un abordaje intraoral paramaxilar asistido con endoscopios para cauterizar la arteria maxilar interna en la fosa infratemporal y un abordaje externo para cauterizar la arteria etmoidal anterior solucionando la epistaxis. (AU)


The clinical case of an 84-year-old patient who had recurrent epistaxis due to Rendu-Osler- Weber disease is described. She had a history of various surgical treatments including closure of the left nostril (Young's operation).Due to the persistence of left epistaxis, angiography and embolization were indicated. The latter was not done because anastomosis between the external and internal carotid system was diagnosed. An intraoral paramaxillary approach assisted with endoscopes was performed to cauterize the internal maxillary artery in the infratemporal fossa and an external approach to cauterize the anterior ethmoidal artery solving the epistaxis.

ABSTRACT

El síndrome de Osler-Weber-Rendu, también conocido como telangiectasia hemorrágica hereditaria, es una enfermedad de herencia autosómica dominante de baja prevalencia, que se caracteriza por unas paredes delgadas de los vasos sanguíneos que conducen a malformaciones arteriovenosas, principalmente en cerebro, pulmón e hígado, pero que pueden potencialmente afectar cualquier otro órgano. La principal manifestación clínica son las epistaxis recurrentes; sin embargo, también pueden aparecer otras manifestaciones como hemoptisis o sangrado gastrointestinal, y telangiectasias mucocutáneas, entre otras. Su expresión clínica varía de un paciente a otro y el diagnóstico usualmente se basa en los criterios de Curazao. Se describe el caso de una paciente con historia de 12 años de epistaxis recurrente, a quien se le diagnosticó síndrome de Osler-Weber-Rendu hace dos años. Fue referida al servicio de Hepatología por presentar compromiso hepático, además de malformaciones arteriovenosas cerebrales y pulmonares. El manejo óptimo de la telangiectasia hemorrágica en esta paciente por parte de los diferentes especialistas, apoyado en los estudios de imagenología, ha permitido que la paciente tenga una buena calidad de vida hasta el momento. Se presenta el caso de esta paciente de 46 años y se realiza una revisión corta de la literatura.


Osler-Weber-Rendu syndrome, also known as hereditary hemorrhagic telangiectasia, is an autosomal dominant low-prevalence disease, characterized by thin blood vessel walls, leading to arteriovenous malformations, mainly in the brain, lung and liver, but can potentially affect any other organ. The main clinical manifestation is recurrent epistaxis; however, other manifestations may also appear, such as hemoptysis or gastrointestinal bleeding, and mucocutaneous telangiectasias, among others. Its clinical expression varies from patient to patient and the diagnosis is usually based on Curacao criteria. We present the case of a patient with a 12-year history of recurrent epistaxis, who was diagnosed with Osler-Weber-Rendu syndrome two years ago. She was referred to the Hepatology service due to liver findings, in addition to brain and pulmonary arteriovenous malformations. The optimal management of hemorrhagic telangiectasia in this patient by the different specialists, supported by imaging studies, has allowed the patient to have a good quality of life. The case of this 46-year-old patient is presented, and a brief literature review is also provided.

ABSTRACT

Resumen El síndrome de Osler-Weber-Rendu es una enfermedad de transmisión autosómica dominante. Si bien el síntoma más común es la epistaxis, existen muchas alteraciones viscerales que deben considerarse al momento del estudio. Los anti-VEFG son un pilar en el tratamiento, aunque no existe consenso acerca de la dosis a administrar. Comunicamos el caso de un paciente con síndrome de Osler-Weber-Rendu atendido en el servicio de Medicina Interna del Hospital Regional de Puebla, al que se prescribió una dosis atípica de bevacizumab con buena respuesta terapéutica.


Abstract Osler-Weber-Rendu syndrome is an autosomical dominant condition. Although epistaxis is the most frequent symptom, many other visceral implications have to be considered while the workup takes place. While Anti-VEGF are the cornerstone of the treatment, there is no consensus regarding the specific dose to be administered. We communicate de case of a patient with Osler-Weber-Rendu syndrome attended at our Hospital in which we prescribed an atypical dose of bevacizumab with good outcome.

ABSTRACT

La epistaxis, es un síntoma frecuente en la consulta de otorrinolaringología. Dentro de las causas posibles encontramos la telangiectasia hemorrágica hereditaria (síndrome de Rendu Osler Weber), que corresponde a un desorden autosómico dominante caracterizado por sangrados nasales y gastrointestinales asociados a malformaciones arteriovenosas sistémicas. Su manifestación más frecuente es la epistaxis, presentándose más frecuentemente en personas mayores de 40 años, sin predilección por género. Se presenta el caso de un paciente de sexo masculino de 46 años quien consulta por epistaxis a repetición y severa. Durante la hospitalización se efectúa el tratamiento convencional de la epistaxis, diagnóstico retroactivo del síndrome de Rendu Osler Weber y manejo multidisciplinario de la patología. Se realiza revisión de la literatura y discusión del manejo del paciente que cursa con esta enfermedad.


Epistaxis is a common symptom in the otorhinolaryngology consultation. Among the possible causes are hereditary hemorrhagic telangiectasia (Rendu Osler Weber syndrome), which corresponds to an autosomal dominant disorder characterized by nasal and gastrointestinal bleeding associated with systemic arteriovenous malformations. Its most frequent manifestation is epistaxis, presenting more frequently in people over 40 years of age, without gender preference. We present the case of a male patient of 46 years old who consults for recurrence and severe epistaxis. During hospitalization, conventional treatment of epistaxis, retroactive diagnosis of Rendu Osler Weber syndrome and multidisciplinary management of pathology are performed. We review the literature and discuss the management of patients with this disease.

ABSTRACT

Abstract Case description: Five-year-old female patient with hereditary hemorrhagic telangiectasia. Clinical Findings: Deterioration of cardiopulmonary function with higher oxygen requirements secondary to pulmonary arteriovenous shunts, epistaxis. Treatment and Outcome: The patient was treated with the monoclonal antibody bevacizumab, which inhibits the vascular endothelial growth factor, with good clinical outcome. Clinical Relevance: Hereditary hemorrhagic telangiectasia is an autosomal dominant disorder characterized by arteriovenous malformations in different organs, making its clinical presentations varied. Systemic therapeutic options for a generalized disease are limited. The monoclonal antibody bevacizumab, seems to be a good option in this disorder. Although reported as successful in adult population, its use in pediatric population has not yet been reported. Here we report the use of bevacizumab in a 5-year-old female patient with hereditary hemorrhagic telangiectasia, showing clinical benefits and good outcome.


Resumen Descripción del caso: Paciente de cinco años de sexo femenino con telangiectasia hemorrágica hereditaria. Hallazgos Clínicos: Deterioro de la función cardiopulmonar con mayores requerimientos de oxígeno secundario a shunt pulmonar arteriovenoso, epistaxis. Tratamiento y resultado: La paciente fue tratada con el anticuerpo monoclonal bevacizumab, que inhibe el factor de crecimiento endotelial vascular, con buen resultado clínico. Relevancia clínica: La telangiectasia hemorrágica hereditaria es un trastorno autosómico dominante caracterizado por malformaciones arteriovenosas en diferentes órganos, lo que hace que sus presentaciones clínicas varíen. Las opciones terapéuticas sistémicas para la enfermedad generalizada son limitadas. El anticuerpo monoclonal bevacizumab, parece ser una buena opción en este trastorno. Aunque se ha reportado como exitoso en la población adulta, su uso en población pediátrica aún no ha sido reportado. Aquí se informa el uso de bevacizumab en una paciente de 5 años de edad con telangiectasia hemorrágica hereditaria, mostrando beneficios clínicos y buen resultado.

ABSTRACT

A Síndrome de Rendu-Osler-Weber, ou Telangiectasia Hemorrágica Hereditária, é doença autossômica dominante com incidência mundial em torno de 1-2/100.000. Caracteriza-se por alteração estrutural dos vasos sanguíneos. O diagnóstico da Síndrome de Rendu-Osler-Weber é feito seguindo os critérios de Curaçao. Múltiplas manifestações sistêmicas são correlacionadas com a Síndrome de Rendu-Osler-Weber, porém seu diagnóstico é difícil de ser estabelecido, em parte pelo desconhecimento da doença e seu manejo (AU)


Rendu-Osler-Weber Syndrome, or Hereditary Hemorrhagic Telangiectasia, is an autosomal dominant disease with a worldwide incidence of around 1-2/100,000. It is characterized by structural alteration of the blood vessels. The diagnosis of Rendu-Osler-Weber Syndrome is made by following the Curaçao criteria. Multiple systemic manifestations are correlated with the Rendu-Osler-Weber Syndrome, but its diagnosis is difficult to establish, partly due to the lack of knowledge about the disease and its management (AU)

ABSTRACT

OBJECTIVES: Hereditary hemorrhagic telangiectasia (HHT) is characterized by the presence of vascular malformations with an absence of capillaries between arteries and veins. One major manifestation site is the nasal mucous membrane where recurrent nosebleeds occur. Our clinical strategy to treat patients with HHT has the aim to reduce nasal bleeding long-term with minimal local and general side effects. METHODS: We describe staged diagnosis and therapy including individual medical treatments of 97 patients with HHT. The success of treatment is monitored with a systematic questionnaire. RESULTS: The neodymium-doped yttrium aluminium garnet (Nd:YAG) laser therapy remains standard treatment of choice with no major side effects despite the need for repeated treatment. In addition new treatment strategies like nasal occlusion, local drug therapy, and nasal septal splinting show initial success. CONCLUSION: Improvement of the quality of life of HHT patients can be achieved by a multimodal concept. Several new treatment strategies like nasal septal splinting and nasal occlusion successfully expand the range of established methods. Further studies have to prove the safety and long-term effectiveness of the described individual medical treatments.

ABSTRACT

Hypertension is an important risk factor for cardiovascular and cerebrovascular diseases,which can damage structure and function of vital organs such as the heart,brain and kidney.Pseudo hypertension (PHT) refers to the blood pressure measured by ordinary cuffmanometry is higher than that of the arterial puncture,which is an essential factor of refractory hypertension.Recent findings have suggested that the elderly patients with concomitant history of atherosclerotic disease,renal insufficiency,and diabetes mellitus have the highest risk of pseudohypertension.The incidence rate ofpseudohypertension is about 1.7%-50% in domestic and international studies.In the clinical treatment,the misdiagnosis of hypertension of patients with excessive blood pressure will lead to severe perfusion defects.In this review,we will focus on the diagnosis and pathogenesis of pseudohypertension.

ABSTRACT

ResumenLa telangiectasia hemorrágica hereditaria o síndrome de Rendu-Osler-Weber, es un desorden autonómico dominante, debido a mutaciones del gen de la endoglina o del gen de la cinasa análoga al receptor de activina. Dicha enfermedad se caracteriza por la presencia de telangiectasias en piel y mucosas, epistaxis recurrente y espontánea, además de malformaciones arteriovenosas en pulmones, cerebro y sistema gastrointestinal. Se ha reportado la asociación entre esta entidad e infecciones en diferentes sitios por Staphylococcus aureus. Los mecanismos de dicha predisposición incluyen la presencia de fístulas arteriovenosas y disfunción polimorfonuclear. Se reporta el caso de una paciente portadora de la enfermedad que asoció osteomielitis vertebral; requirió tratamiento antibiótico prolongado y cirugía de fusión e instrumentación de la columna vertebral a nivel torácico. Es necesario considerar este tipo de infecciones en pacientes con tal enfermedad, lo cual puede ayudar a la escogencia del tratamiento antibiótico y del manejo del paciente más expedito.


AbstractHereditary Hemorrhagic Telangiectasia or Osler-Weber-Rendu syndrome is a dominant autonomic disorder caused by mutations of the endoglin gene or the kinase gene similar to the activin receptor. This disease is characterized by the presence of telangiectasia on skin and mucous, recurrent and spontaneous epistaxis, as well as arteriovenous malformations in lungs, brain and gastrointestinal system. The association between this disease and infections in several places of the body with Staphylococcus aureushas been reported. The mechanisms of this predisposition include the presence of arteriovenous fistulas and polymorphonuclear dysfunction. A case is reported about a patient carrying the disease associated with vertebral osteomyelitis, who required a prolonged antibiotic treatment and instrumentation of the vertebral column at thoracic level. It is necessary to consider this type of infections in patients with this disease, which may help when choosing the antibiotic treatment and a more expeditious patient management.

ABSTRACT

La telangiectasia hemorrágica hereditaria (THH) o el síndrome de Osler Weber Rendu, es una enfermedad autosómica dominante caracterizada por telangectasias mucocutaneas, epistaxis y sangrados digestivos recurrentes y por el desarrollo de malformaciones arteriovenosas (MAV) en órganos como cerebro, pulmón e hígado. Se estima que su prevalencia es de un caso en 5000 a 8000. Esta malformación vascular multisistémica tiene dos diferentes presentaciones, HHT1 y HTT2, la primera presenta mutaciones en el gen de endoglina (ENG), localizado en el cromosoma 9 y en la segunda presentación se observan mutaciones en el gen ALK1, localizado en el cromosoma 12, ambos genes cumplen un rol importante durante la angiogénesis. Las telangiectasias en la mucosa nasal y gastrointestinal generalmente resultan en sangrados crónicos y recurrentes y en anemia ferropénica. Las malformaciones arteriovenosas de mayor tamaño ocurren principalmente en los pulmones, hígado, cerebro y médula espinal. Es de suma importancia el tamizaje y el tratamiento presintomático ya que las complicaciones son potencialmente fatales, sin embargo, dado la rareza de este, con frecuencia es subdiagnosticado lo que conlleva a una alta morbilidad.El siguiente artículo provee una revisión de las características clínicas del síndrome, discute el tamizaje y las estrategias diagnósticas, presenta las opciones terapéuticas actuales y las modalidades de prevención empleadas actualmente y el seguimiento recomendado internacionalmente.


Hereditary hemorrhagic telangiectasia (HHT), also known by the eponym Osler-Weber-Rendu syndrome is an autosomal dominant familial disorder characterized by mucocutaneous telangiectasia, epistaxis, recurrent GI bleeding and by the development of arteriovenous malformations (AVM) in organs such as brain, lungs, and liver.Its prevalence is currently estimated at one in 5,000 to 8,000. This multisystemic vascular alteration disease has two different presentations, HHT1 and HHT2, the former is associated with mutations on the endoglin gen (ENG) localized in the 9th chromosome and the latter is associated with mutations in the activin receptor-like kinase 1 (ALK1) gen, localized in the 12th chromosome, both genes have an important role on the properties of endothelial cells during angiogenesis. Telangiectasias in nasal and gastrointestinal mucosa may lead to recurrent or chronic bleeding and iron deficiency anemia. Larger AVMs occur in lungs, liver, brain, and spine. It's of utmost importance the presymptomatic screening and treatment due to the potentially fatal complications if this disorder, however, due to the rarity of this condition, its frequently underdiagnosed leading to a poor prognosis.This article provides an overview of the clinical features of HHT, discusses the screening and diagnostic strategies, and presents the actual treatment options and the international recommended surveillance.

ABSTRACT

La telangiectasia hemorrágica hereditaria (THH) o síndrome Rendu Osler Weber es un trastorno autosómico dominante que lleva a la formación anormal de vasos sanguíneos y se manifiesta como telangiectasias y malformaciones arteriovenosas en piel y órganos internos. Mujer de 72 años con antecedentes de hipertensión arterial, anemia ferropénica e hipertensión pulmonar en tratamiento. Es derivada a dermatología por la presencia durante años de lesiones asintomáticas en cara y manos. Refiere 4 episodios de epistaxis durante su vida y no tiene historia familiar de patologías dermatológicas. Al examen se observan múltiples máculas eritemato-violáceas, con vitropresión positiva, algunas conformadas por telangiectasias, localizadas en la región malar, frente, lengua y ambas palmas. Se excluyó compromiso hepático, pero se encontraron lesiones vasculares en estómago y duodeno. Con estos antecedentes, se confirmó el diagnóstico de THH. La THH es un diagnóstico clínico basado en los criterios de Curaçao: epistaxis, telangiectasias, lesiones viscerales e historia familiar. Desde el punto de vista dermatológico, se presenta con telangiectasias en palmas, dedos, labios y lengua. Aunque la epistaxis u otras presentaciones pueden ser las manifestaciones más incapacitantes o peligrosas, las telangiectasias extranasales pueden ser más importantes para el paciente, llevándolo a consultar a dermatología. Los dermatólogos deben considerar este síndrome, a pesar de su baja incidencia reportada, debido a sus posibles complicaciones. El tratamiento es sólo paliativo, sin consenso sobre la mejor opción de manejo. Es esencial promover un control a largo plazo de la enfermedad.


Hereditary hemorrhagic telangiectasia (HHT) or Rendu Osler Weber syndrome is an autosomal dominant disorder that leads to abnormal blood vessels formation. It manifests as telangiectasias and arteriovenous malformations in the skin and internal organs. A 72-year-old female patient with previous medical history of hypertension, iron deficiency anemia, and pulmonary hypertension in treatment was referred to our clinic due to the presence of asymptomatic acral lesions. She reported only four epistaxis events throughout her life, and had no family history bleeding. Examination showed multiple, blanching, erythematous-violaceous macules. On the malar region, forehead, tongue and palms, some telangiectasias were grouped. No hepatic lesions were found, however, stomach and duodenum vascular malformations were found after workup; prompting the diagnosis of HHT . HHT diagnosis is made clinically based on the Curaçao criteria: epistaxis, telangiectasias, visceral lesions and family history. From a dermatological point of view, it is presented with telangiectases in palms, fingers, lips and tongue. However, epistaxis or other vascular malformations may be life-threatening. Dermatologists should be aware of the existence of HHT, despite its low reported incidence, due to its frequent cutaneous manifestations and potential complications. Treatment is only palliative, with no consensus on the best management option. It is essential to promote long-term control of the disease.

ABSTRACT

La telangiectasia hemorrágica hereditaria o síndrome de Osler-Weber-Rendu es una entidad autosómica dominante rara, con una frecuencia que oscila entre 1 por cada 16 300 habitantes a 1 por cada 1331 dependiendo de la población y la localización geográfica, sin predilección de género. Se caracteriza clínicamente por telangiectasias, epistaxis a repetición, lesiones viscerales vasculares (malformaciones arteriovenosas) y usualmente con un antecedente familiar. Este trabajo reporta un caso clínico compatible con esta entidad que presentó complicaciones muy raras como lo son el absceso pulmonar y cerebral a la vez.


Hereditary hemorrhagic telangiectasia (HHT) (also known as Osler Weber Rendu syndrome (OWRS)) is a rare dominant autosomal disorder whose frequency is between 1 per 1,331 people and 1 per 16,300 people depending on the population and its geographical location. There are no differences between genders. It is clinically characterized by telangiectasia, recurrent epistaxis, visceral vascular lesions (arteriovenous malformations - AVMs). Usually a person with HHT has a family history of the disorder. This paper reports a case that is clinically compatible with this rare entity and which presented simultaneous complications of pulmonary and cerebral abscesses.
