Chronic liver disease-associated severe thrombocytopenia in Spain: Results from a retrospective study using machine learning and natural language processing.

BACKGROUND: Patients with chronic liver disease (CLD) often develop thrombocytopenia (TCP) as a complication. Severe TCP (platelet count<50×109/L) can increase morbidity and complicate CLD management, increasing bleeding risk during invasive procedures. OBJECTIVES: To describe the real-world scenario of CLD-associated severe TCP patients' clinical characteristics. To evaluate the association between invasive procedures, prophylactic treatments, and bleeding events in this group of patients. To describe their need of medical resource use in Spain. METHODS: This is a retrospective, multicenter study including patients who had confirmed diagnosis of CLD and severe TCP in four hospitals within the Spanish National Healthcare Network from January 2014 to December 2018. We analyzed the free-text information from Electronic Health Records (EHRs) of patients using Natural Language Processing (NLP), machine learning techniques, and SNOMED-CT terminology. Demographics, comorbidities, analytical parameters and characteristics of CLD were extracted at baseline and need for invasive procedures, prophylactic treatments, bleeding events and medical resources used in the follow up period. Frequency tables were generated for categorical variables, whereas continuous variables were described in summary tables as mean (SD) and median (Q1-Q3). RESULTS: Out of 1,765,675 patients, 1787 had CLD and severe TCP; 65.2% were male with a mean age of 54.7 years old. Cirrhosis was detected in 46% (n=820) of patients and 9.1% (n=163) had hepatocellular carcinoma. Invasive procedures were needed in 85.6% of patients during the follow up period. Patients undergoing procedures compared to those patients without invasive procedures presented higher rates of bleeding events (33% vs 8%, p<0.0001) and higher number of bleedings. While prophylactic platelet transfusions were given to 25.6% of patients undergoing procedures, TPO receptor agonist use was only detected in 3.1% of them. Most patients (60.9%) required at least one hospital admission during the follow up and 14.4% of admissions were due to bleeding events with a hospital length of stay of 6 (3, 9) days. CONCLUSIONS: NLP and machine learning are useful tools to describe real-world data in patients with CLD and severe TCP in Spain. Bleeding events are frequent in those patients who need invasive procedures, even receiving platelet transfusions as a prophylactic treatment, increasing the further use of medical resources. Because that, new prophylactic treatments that are not yet generalized, are needed.

Epistaxis in the cirrhotic patient: A complication to be considered. / Epistaxis en el paciente cirrótico: una complicación a tener en cuenta.

INTRODUCTION: Epistaxis in cirrhotic patients is a common issue. However, the literature published to date is very scarce. MATERIAL AND METHODS: Retrospective case series of patients with cirrhosis who presented with a significant epistaxis, between 2006 and 2016. RESULTS: Data were collected from 39 cirrhotic patients with a mean age of 61.4 (±14) years, 75% of which were males. The main comorbidities were hypertension (33%) and diabetes mellitus (26%). Seven (18%) patients were taking antiplatelet drugs and 3 (8%) anticoagulants. One third of patients had a previous history of epistaxis and 6 had a previous ENT pathology. The main aetiological factor of cirrhosis was alcohol in 46% of cases, with 15 (38%) patients presenting with Child A, 12 (31%) Child B and 12 (31%) Child C class. The median MELD score upon admission was 16 [12-21]. Thirty-five (97%) patients had portal hypertension. At admission, the median platelet count was 89,000 [60,000-163,000] and mean INR was 1.52 (±0.37). Clinically, epistaxis presented as haematemesis or melaena in 8 (21%) patients, simulating gastrointestinal bleeding due to swallowing of blood. In 10 (26%) patients, epistaxis was considered as the probable trigger of an episode of hepatic encephalopathy. Two patients required ICU admission due to bleeding and 8 (21%) died during hospitalisation due to causes not directly related to epistaxis. CONCLUSIONS: Epistaxis is a complication to be taken into account in cirrhotic patients, as it can act as an encephalopathy trigger or simulate an episode of gastrointestinal bleeding.

[Autoimmune hepatitis in the pediatric age]. / Hepatitis autoinmune en la edad pediátrica.

In pediatrics, autoimmune hepatitis and sclerosing cholangitis are liver disorders with an immunological damage mechanism. Autoimmune hepatitis is a disease of unknown etiology characterized by interface hepatitis, hypergammaglobulinemia, circulating autoantibodies and a favorable response to immunosuppression. It is an eminently pediatric disease with a prevalent condition in young women. Therapy should be instituted promptly to prevent rapid deterioration, promote remission of disease and long-term survival. The persistent lack of response or lack of adherence to treatment results in terminal liver failure; these patients, and those with fulminant hepatic insufficiency at the time of diagnosis, will require liver transplantation.

Elastografia por ressonância magnética para avaliação de doença hepática gordurosa não alcoólica / Magnetic resonance elastography for evaluation of non-alcoholic fatty liver disease

Introdução: A doença hepática gordurosa não alcoólica (DHGNA) é uma das causas mais comuns de hepatopatia. Devido ao grande risco de progressão para cronicidade, seu rastreamento se faz necessário. A Elastografia por Ressônancia Magnética (MRE) foi estabelecida em diversos estudos como uma técnica acurada para o diagnóstico de fibrose. Objetivos: Descrever a prevalência de esteatose e de fibrose hepática em pacientes com DHGNA submetidos à MRE; estimar o grau de fibrose, correlacionando com a escala METAVIR, e avaliar a fração de gordura por densidade de prótons (PDFF) e os fatores clínicos associados à esteatose e fibrose. Métodos: Estudo transversal, realizado mediante revisão de imagens de MRE, entre janeiro de 2017 e março de 2019, em um hospital da região sul do Brasil. Resultados: Dos 298 pacientes incluídos, a maioria dos pacientes apresentava esteatose leve (41,6%, n=124) ou ausente (30,9%, n=92), enquanto 15,1% (n=45) apresentava esteatose moderada e 12,4% (n=37), acentuada. A maioria dos pacientes (65,8%, n=181) apresentava rigidez hepática dentro da normalidade, 11,6% (n=32) inflamação crônica, 7,6% (n=21) fibrose estágio 1-2, 3,6% (n=10) fibrose estágio 2-3, 4,7% (n=13) fibrose estágio 3-4 e 6,5% (n=18) fibrose estágio 4 ou cirrose. Discussão: Os resultados encontrados nesta amostra reforçam os fatores de risco para o desenvolvimento de DHGNA previamente avaliados. Uma combinação de estratégias não invasivas, incluindo a MRE, poderá selecionar os pacientes com maior probabilidade de agravos. Conclusão: Nesse estudo, a maioria dos pacientes apresentou a forma leve ou ausência de esteatose e rigidez hepática dentro da normalidade. A MRE tem se mostrado uma técnica altamente acurada, não invasiva para estadiamento de fibrose hepática em pacientes com DHGNA, sem influência significativa da idade, sexo, adiposidade e grau de inflamação hepática.

Introduction: Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of liver disease. Due to the high risk of progression to chronicity, its tracking is necessary. Magnetic Resonance Elastography (MRE) has been established in several studies as an accurate technique for diagnosing fibrosis. Objectives: To describe the prevalence of steatosis and liver fibrosis in NAFLD patients undergoing MRE; estimate the degree of fibrosis, correlating with the METAVIR scale, and assess the proton density fat-fraction (PDFF). Methods: A cross-sectional study, performed by reviewing MRE images, between January 2017 and March 2019, in a hospital in southern Brazil. Results: Of the 298 patients included, most patients had mild (41.6%, n=124) or absent (30.9%, n=92) steatosis, while 15.1% (n=45) had moderate and 12.4% (n=37) marked steatosis. Most patients (65.8%, n=181) had liver stiffness within the normal range, 11.6% (n=32) chronic inflammation, 7.6% (n=21) stage 1-2 fibrosis, 3.6% (n=10) stage 2-3 fibrosis, 4.7% (n=13) stage 3-4 fibrosis, and 6.5% (n=18) stage 4 fibrosis or cirrhosis. Discussion: The results found in this sample reinforce the risk factors for the development of NAFLD previously evaluated. A combination of non-invasive strategies, including MRE, may select the patients with the greatest likelihood of harm. Conclusions: MRE has been shown to be a highly accurate, non-invasive technique for staging liver fibrosis in NAFLD patients, with no significant influence of age, sex, adiposity, and degree of liver inflammation.

Efecto del consumo de alcohol al diagnóstico en la sobrevida de pacientes con cirrosis hepática en un hospital universitario de la ciudad de Medellín / Effect of alcohol consumption on diagnosis of liver cirrhosis patients' survival at a University Hospital in Medellín

Resumen El consumo de alcohol es un conocido factor de riesgo para muerte prematura, morbilidad y discapacidad a nivel mundial. Los registros de la mortalidad que se asocian con el consumo de alcohol están fraccionados. El objetivo de este estudio fue escribir la mortalidad relacionada con la ingesta de alcohol en pacientes con cirrosis atendidos en un hospital universitario de la ciudad de Medellín. Materiales y métodos: se incluyeron 163 pacientes con diagnóstico de cirrosis, evaluados en la consulta externa de hepatología de un hospital de referencia en la ciudad de Medellín con 277 camas y seguimiento hasta el 2016. Se midieron variables sociodemográficas, paraclínicas y clínicas. Se consideró el consumo de alcohol al inicio del seguimiento. Se describió la supervivencia y las complicaciones asociadas con la cirrosis según el estado de consumidores vs. no consumidores de alcohol. Resultados: se siguieron 163 pacientes hasta diciembre del 2016, encontrando una mortalidad en el 51% en consumidores de alcohol vs. 39% en no consumidores (P = 0,19). Las complicaciones de la cirrosis en consumidores de alcohol fueron ascitis en 68% vs. 43% (P = 0,01) en el grupo sin consumo de alcohol, encefalopatía 40,6% vs. 13,5% (P = 0,00) y carcinoma hepatocelular (HCC) en 29% vs. 17% (P = 0,08). En el análisis por subgrupos, los pacientes con hepatitis C con consumo de alcohol tuvieron una mortalidad más alta comparado con los pacientes que no consumieron alcohol (OR 33, IC 95%: 1,06 a 1023). Conclusiones: a pesar que el consumo de alcohol no se relaciona con aumento de la mortalidad en pacientes con cirrosis en este estudio, sí se observa incremento de esta en ciertas poblaciones, como en el subgrupo de pacientes con hepatitis C.

Abstract Worldwide, alcohol consumption is a well-known risk factor for premature death, morbidity and disability. Records of mortality associated with alcohol consumption are not centralized. The aim of this study was to record the mortality rate associated with alcohol intake in patients with cirrhosis who were treated at a university hospital in the city of Medellin. Materials and methods: We included 163 patients who had been diagnosed with cirrhosis in the outpatient hepatology clinic of a 277 bed referral hospital in Medellín. Patients were monitored until 2016. Sociodemographic, paraclinical and clinical variables were measured. Alcohol consumption was considered at the beginning of the follow-up. Survival and complications associated with cirrhosis were described and recorded for patients who consumed alcohol as well as for those who did not, and then the two groups were compared. Results: One hundred sixty-three patients were followed until December 2016. The mortality rate among those who consumed alcohol was 51% while it was only 39% for those who did not consume alcohol (P = 0.19). Comparison of complications of cirrhosis showed that 68% of alcohol users developed ascites vs. 43% of non-consumers (P = 0.01); 40.6% of alcohol users developed encephalopathy vs. 13.5% of non-consumers (P = 0.00); and 29% of alcohol users developed hepatocellular carcinoma (HCC) vs. 17% of non-consumers (P = 0.08). In the subgroup analysis, patients with hepatitis C who consumed alcohol had a higher mortality rate than patients who did not consume alcohol (OR: 33, 95% CI: 1.06 to 1023). Conclusions: Although alcohol consumption was not related to increased mortality among patients with cirrhosis in this study, increased mortality was observed in the subgroup of patients with hepatitis C.

Hepatitis autoinmune en la edad pediátrica / Autoimmune hepatitis in the pediatric age

Resumen: En pediatría, la hepatitis autoinmune y la colangitis esclerosante son patologías de afección hepática cuyo mecanismo de daño es inmunológico. La hepatitis autoinmune es una enfermedad de etiología desconocida, caracterizada por hepatitis de interfase, hipergammaglobulinemia, autoanticuerpos circulantes y una respuesta favorable a la inmunosupresión. Es una enfermedad eminentemente pediátrica, con una afección prevalente hacia mujeres jóvenes. La terapia debe ser instituida con prontitud para prevenir el deterioro rápido, promover la remisión de la enfermedad y la supervivencia a largo plazo. La falta persistente de respuesta o la falta de adherencia al tratamiento dan como resultado una enfermedad hepática terminal. Los pacientes que desarrollan esta patología, y aquellos con insuficiencia hepática fulminante en el momento del diagnóstico, requerirán trasplante hepático.

Aspectos epidemiológicos, clínico-patológicos e diagnóstico precoce da seneciose bovina no Oeste do Rio Grande do Sul / Epidemiological, clinical and pathological aspects and early diagnosis of bovine seneciosis in the Western region of Rio Grande do Sul, Brazil

A ingestão de Senecio spp. (maria-mole) é, possivelmente, a principal causa de morte de bovinos por agentes tóxicos nas regiões central e sul do Rio Grande do Sul. Ao considerar a limitação de informações acerca dessa condição no Oeste do Rio Grande do Sul, esse trabalho objetiva descrever os principais aspectos epidemiológicos e clínico-patológicos da seneciose em bovinos nessa região. O estudo foi realizado por meio da aplicação de questionários em 16 propriedades rurais de municípios da região que apresentaram casos suspeitos da intoxicação em bovinos, de agosto de 2011 a março de 2014. Durante as visitas as propriedades foram coletadas plantas do gênero Senecio para identificação botânica, bem como se procedeu a coleta de fragmentos de fígado através de biópsia transtorácica para confirmação da intoxicação. As espécies de Senecio mais frequentes nas propriedades foram S. brasiliensis e S. heterotrichius. De um total de 88 bovinos, de nove propriedades distintas, que apresentaram falha no ganho de peso, 69 animais (aproximadamente 80%) foram positivos para seneciose crônica por apresentarem lesões características da intoxicação, tais como fibrose periportal (78% dos casos), megalocitose (76% dos casos) e proliferação de ductos biliares (68% dos casos), classificadas entre discretas e acentuadas. O trabalho confirmou a ocorrência da doença, mesmo em bovinos sem sinais clínicos evidentes. Os resultados obtidos nessas avaliações foram fundamentais para orientar proprietários e técnicos quanto às principais características da doença e às formas de controle a serem adotadas. O emprego da biópsia hepática possibilitou o diagnóstico precoce da intoxicação e auxiliou os criadores quanto ao descarte mais criterioso de bovinos e a real situação da intoxicação no rebanho, minimizando as perdas econômicas.(AU)

The ingestion of Senecio spp. (ragwort) is perhaps the leading cause of death of cattle in central and southern Rio Grande do Sul, Brazil. Considering the limited information about this condition in the Western region of Rio Grande do Sul, Brazil, this paper describes main epidemiological clinical and pathological aspects of seneciosis in cattle. The assessments were made through questionnaires on 16 rural properties which had suspected cases of poisoning in cattle, from August 2011 to March 2014. During the visits were evaluated epidemiological aspects of poisoning and performed sample collection of Senecio plants for botanical identification, as well as collection of liver samples using transthoracic biopsy for confirmation of the poisoning. Senecio species most common on farms were S. brasiliensis and S. heterotrichius. From 88 cattle that failed to thrive on nine different farms, 69 animals (about 80%) were positive for chronic seneciosis with periportal fibrosis (78% of cases), megalocytosis (76% of cases) and with bile duct proliferation (68% of cases). Lesions were classified as mild, moderate or marked. The current study confirms the occurrence of this poisoning, even in cattle without evident clinical signs. The use of liver biopsy enabled the early diagnosis of poisoning and helped farmers carefully to dispose affectd cattle, as well as to recognize the real situation of poisoning in the herd and minimize economic losses.(AU)

Factores de riesgo de la enfermedad hepática grasa no alcohólica / Risk factors for non-alcoholic fatty liver disease

Prevalence of non-alcoholic fatty liver disease (NAFLD) may be 10%-15% worldwide, and these figures are even higher in obese and in type 2 diabetes mellitus patients. The most important risk factor is metabolic syndrome, especially central obesity. Even though the majority of patients with macrovesicular steatohepatitis will not progress to advanced liver disease, a subgroup of patients will evolve to non-alcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma. Independent risk factors associated with NASH are older age, type 2 diabetes mellitus and obesity. Patients with significant hepatocellular lesion, such as hepatocyte ballooning, Mallory hyalline or fibrosis, have a higher risk of cirrhosis and are more likely to have a high liver-related mortality, although higher global mortality has not been demonstrated. Although NASH related cirrhosis may have better prognosis compared to hepatitis C cirrhosis, recent series suggest that it may be the third cause of liver transplantation. Steatosis, NASH and cirrhosis recurrence post-liver transplantation is common. The risk of hepatocellular carcinoma (HCC) is increased in patients with NAFLD, and all patients with cryptogenic cirrhosis should be screened for HCC

La enfermedad hepática grasa no alcohólica puede afectar al 15%-25% de la población, con cifras mayores en pacientes obesos y con diabetes mellitus tipo 2. El principal factor de riesgo es el síndrome metabólico, especialmente la obesidad central. Aunque la mayoría de los pacientes con esteatosis macrovacuolar simple no presentan progresión de su enfermedad, existe un subgrupo que progresa a esteatohepatitis no alcohólica, y aunque se desconocen los factores de riesgo para esta progresión, la mayoría de los estudios reconocen la edad, la presencia de diabetes mellitas tipo 2 y la obesidad como predictores de riesgo independientes de EHNA. La presencia de lesión hepatocelular significativa, como el abalonamiento hepatocitario o la hialina de Mallory y la fibrosis, incrementan significativamente el riesgo de cirrosis. Los pacientes que tienen esta lesión histopatológica presentan una mortalidad de causa hepática superior, si bien no se ha demostrado una mortalidad global aumentada. Aunque la cirrosis secundaria a esteatohepatitis no alcohólica parece tener un pronóstico ligeramente mejor que la secundaria a hepatitis C, en muchas series es la tercera causa de trasplante ortotópico de hígado. La recurrencia postrasplante de la esteatosis, de la esteatohepatitis no alcohólica y de la cirrosis es frecuente. Existe un aumento del riesgo de hepatocarcinoma en pacientes con enfermedad hepática grasa no alcohólica. En la actualidad se recomienda el seguimiento para la detección precoz de este tumor en todos los pacientes con cirrosis criptogénica

Trastornos de la hemostasia en la enfermedad hepática crónica / Coagulation Disorders in Chronic Liver Disease

El mecanismo de la coagulación normal funciona sobre base la de un complicado balance entre mecanismos procoagulantes, anticoagulantes y sistema fibrinolítico, y el hígado juega un rol esencial en él. Se realizó una revisión con el objetivo de examinar aspectos relacionados con las alteraciones en la hemostasia en los pacientes con hepatopatía crónica, para ello se efectuó una búsqueda bibliográfica sobre el tema en Pubmed, EBSCO, Medline, e Hinari. Se abordaron las alteraciones plaquetarias cuantitativas y cualitativas, déficit en la síntesis de factores de la coagulación, disfibrinogenemia, alteraciones en la fibrinólisis, deficiencia de vitamina K y cambios compatibles con un estado de coagulación intravascular diseminada. Se concluyó que Las alteraciones de la hemostasia en el paciente cirrótico se relacionan con un estado avanzado de la enfermedad, con consecuencias clínicas que constituyen un espectro que incluyen tendencia al sangrado, o a fenómenos de trombosis, y que las pruebas de coagulación habituales no reflejan de manera adecuada las alteraciones de la hemostasia en el paciente con enfermedad hepática crónica. No obstante, los recientes avances en la exploración analítica de estos trastornos constituyen promisorias herramientas para su diagnóstico apropiado en el área clínica.

Normal haemostasis performs based on a complex balance between procoagulant, anticoagulant mechanisms and the fibrinolytic system, in which the liver exerts an important role. A review was performed aimed at examining aspects in relation with the hemostatic alterations in patients with chronic liver disease. A bibliographical review was done to accomplish that purpose in Pubmed, EBSCO, Medline, and Hinari database. Platelet quantitative and qualitative abnormalities and diminished synthesis of clotting factors were approached, as well as dysfibrinogenemia, fibrinolysis disorders, vitamin K deficiency, and a state compatible with disseminated intravascular coagulation. The following conclusions were made: the hemostatic disorders in the patient with cirrhosis are related to an advanced state of the disease, with clinical consequences which are in a wide spectrum from bleeding tendency to thrombosis, and that the standard coagulation tests do not appropriately reflect these phenomena. Nevertheless, recent advances in analytical techniques for the diagnosis of these abnormalities constitute promising tools for their proper identification in the clinical context.

Ultrasonografía vascular en pacientes con hepatopatías crónicas de causa desconocida / Vascular ultrasonography in patients with chronic hepatopathies of unknown etiology

Se realizó un estudio prospectivo y transversal de 69 pacientes con hepatopatías crónicas de causa desconocida, atendidos en el Departamento de Imagenología del Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, desde enero del 2009 hasta agosto del 2010, a fin de determinar las alteraciones ultrasonográficas vasculares en los afectados. Predominaron el grupo etario de 52-59 años (39,1 %), el sexo masculino (69,6 %), la localización prehepática (44,9 %), las trombosis de la vena porta (47%), la dilatación de venas suprahepáticas (89,7%) y las causas prehepáticas (44,9%). Las ecografías Doppler dúplex y Doppler color permitieron establecer pautas diagnósticas en estos pacientes, sin afectar el completamiento de su evaluación con otros estudios hemodinámicos.

A prospective and cross-sectional study of 69 patients with chronic hepatopathies of unknown etiology, assisted in the Imagenology Department of "Saturnino Lora Torres" Teaching Provincial Clinical Surgical Hospital in Santiago de Cuba was carried out from January, 2009 to August, 2010, in order to determine the ultrasonographic vascular changes in the affected patients. The age group 52-59 (39.1%), the male sex (69.6%), the localization (44.9%), the thromboses of the portal vein (47%), the dilation of suprahepatic veins (89.7%) and the prehepatic etiologies (44.9%) prevailed. The Doppler duplex and Doppler colour echographies allowed to establish diagnostic criteria in these patients, without affecting their evaluation with other hemodynamic studies.

Evaluación nutricional de pacientes con cirrosis hepática / Nutritional evaluation of patients with hepatic cirrhosis

Se realizó un estudio descriptivo y transversal de 60 pacientes con cirrosis hepática, asistidos en el Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, desde enero del 2009 hasta diciembre del 2011, con vistas a evaluarles desde el punto de vista nutricional. En la serie predominaron el sexo masculino (53,3 %), el grupo etario de 35-60 años (58,3 %), la evolución clínica de menos de 10 años (55,0 %) y el alcohol como causa de la afección (35,0 %); de igual modo, 54,9 % de los afectados presentaban grados diferentes de desnutrición, la cual fue más grave en quienes adquirieron la enfermedad por consumo alcohólico. Los parámetros de laboratorio más alterados se observaron en las cifras de albúmina, colesterol y hemoglobina, así como en las pruebas de inmunorreactividad cutánea, en ese orden. Para dar por concluido, los mayores grados de desnutrición se asociaron al alcohol como causa de la hepatopatía y al estadio avanzado de esta.

A descriptive and cross-sectional study of 60 patients with hepatic cirrhosis, attended in "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba was carried out from January, 2009 to December, 2011, aimed at evaluating them from the nutritional point of view. The male sex (53.3%), the age group 35-60 years (58.3%), the clinical course of less than 10 years (55.0%) and the alcohol as cause of the disorder (35.0%) prevailed in the series; likewise, 54.9% of those affected presented different degrees of malnutrition, which was more serious in those who acquired the disease due to alcoholic consumption. The most altered laboratory parameters were observed in the albumin, cholesterol and hemoglobin levels, as well as in the tests for cutaneous immunorreactivity, in that order. To concluded, the highest degrees of malnutrition were associated with the alcohol as cause of the hepatopathy and to its advanced stage.

Predictores de mortalidad hospitalaria en la hemorragia digestiva alta variceal por hepatopatía crónica tratada endoscópicamente / Predictors of intrahospitalary mortality in the upper gastrointestinal variceal bleeding due to chronic liver disease treated endoscopically

La hemorragia digestiva alta variceal es una de las complicaciones más graves en la hepatopatía crónica. El objetivo de este trabajo es identificar variables que predicen mortalidad hospitalaria. Material y métodos: 106 internaciones por esta patología desde octubre de 2001 hasta abril de 2006 en diseño de cohortes. Se confrontó mortalidad hospitalaria con edad, sexo, etiología de la hepatopatía, score APACHE II al ingreso, imensión de las várices evaluada endoscópicamente, severidad de la insuficiencia hepática evaluada por clases de Child Pugh, antecedente de hemorragia variceal, fracaso de la terapia endoscópica inicial, fracaso hemostático en las primeras 48hs y resangrado posterior a 48hs. Para identificar predictores independientes de mortalidad se seleccionaron todas las variables que correlacionaron significativamente con muerte hospitalaria. Para la variable cuantitativa score APACHE II de ingreso se consideró el valor que mejor discriminó mortalidad. Resultados: los predictores independientes de muerte hospitalaria fueron: el fracaso de la terapia endoscópica inicial (p=0,005), el fracaso hemostático en las primeras 48hs (p=0,012) y la clase C de Child Pugh (p=0,024). Si bien en el sexo masculino el score APACHE II al ingreso y el resangrado con posterioridad a las 48hs también correlacionaron con mortalimortalidad, no calificaron como predictores independientes. Conclusión: en portadores de hepatopatía crónica con hemorragia digestiva alta variceal y primera línea de tratamiento endoscópico, resultaron predictores independientes de muerte hospitalaria: 1) el fracaso de la terapia endoscópica hemostática inicial, 2) el fracaso hemostático en las primeras 48hs, y 3) la clase C de Child Pugh al ingreso.

Upper gastrointestinal variceal bleeding is one of the most serious complications in patients with chronic liver disease. The aim of this trial is to identify in hospital mortality predictors in this illness. Material and methods: 106 hospitalizations due to this disease from October 2001 to April 2006 in cohort design. In hospital mortality was confronted with age, sex, liver disease etiology, Apache II score at admission, variceal severity, severity of the hepatic failure evaluated according to the Child Pugh’s classes, a history of variceal bleeding, initial endoscopic treatment failure, haemostatic failure within the first 48 hours, and rebleeding after 48 hours from admission. In order to identify independent mortality predictors, all the variables correlated significantly with hospital mortality were selected. For the quantitative variable APACHE II score at admission, the best mortality discrimination value was chosen. Results: independent in hospital mortality predictors were: initial endoscopic treatment failure (p = 0,005), haemostatic failure in the first 48 hours (p = 0,012), and Child Pugh C class (p = 0,024). Although male sex, Apache II score at admission and rebleeding after 48 hours were also significantly related to mortality by univaried model, they did not qualify as independent predictors. Conclusions: the independent predictors of intrahospitalary mortality in patients with variceal bleeding due to chronic liver disease, and firstline of endoscopic treatment were: 1) Initial haemostatic endoscopic treatment failure, 2) Haemostatic failure in the first 48hs, and 3) Child Pugh C class hepatic failure at admission.
