Abstract: Introduction: Bacterial infections in cirrhotic patients are a frequent complication, which occurs mainly in advanced stages of the disease. Non-spontaneous infections or infections not related to portal hypertension include mainly those of the urinary tract, acute pneumonia, and skin and soft tissue infections. They generate a significant impact on the evolution of the disease, since they increase morbidity and mortality, and are also the most common precipitating factor of acute over chronic liver failure, a serious condition with high short-term mortality. The objective of this work is to know the incidence, and describe the clinical, epidemiological, microbiological, and evolutionary characteristics of non-spontaneous bacterial infections, in patients with liver cirrhosis, admitted to the Military Hospital, in the period between March 2018 and December 2020. Methodology: A cross-sectional, descriptive and single-center study was carried out, which included hospitalized patients, diagnosed with liver cirrhosis, who presented a bacterial infection not related to portal hypertension on admission or during hospital stay. Data were analyzed using frequency distribution and summary measures for the different variables. The incidence of non-spontaneous bacterial infections was calculated based on the total population of cirrhotic patients admitted during that period. Results: Of the total number of cirrhotic patients admitted, 17.5% had a bacterial infection not linked to portal hypertension, with a mean age of 61 years, 70% being men. The main etiology of cirrhosis was alcoholic. The vast majority of patients (95%) presented an advanced stage of liver disease (60% Child-Pugh stage B and 35% stage C), with a mean MELD-Na of 21. The most frequent infection was that of the urinary tract (50%), followed by acute pneumonia (20%), skin and soft tissue infections (10%) and acute cholangitis (10%). The most prevalent microorganisms were gram negative bacilli such as Klebsiella pneumoniae and Escherichia coli. 40% of the patients presented acute-on-chronic liver failure at the time of admission and an additional 5% developed it during evolution. Of this group of patients, 20% died during hospitalization. Conclusions: The present study constitutes an approximation to the knowledge of non-spontaneous infections in cirrhotic patients, being necessary the development of studies with a greater number of patients in order to establish a statistically significant association between the presence of bacterial infection and the development of acute on chronic liver failure, and from this with short-term mortality.


Resumo: Introdução: Infecções bacterianas em pacientes cirróticos são uma complicação frequente, que ocorre principalmente em estágios avançados da doença. Infecções não espontâneas ou infecções não relacionadas à hipertensão portal incluem principalmente aquelas do trato urinário, pneumonia aguda e infecções de pele e tecidos moles. Geram um impacto significativo na evolução da doença, pois aumentam a morbidade e a mortalidade, sendo também o fator precipitante mais comum da insuficiência hepática aguda sobre a crônica, uma condição grave com alta mortalidade em curto prazo. O objetivo deste trabalho é conhecer a incidência e descrever as características clínicas, epidemiológicas, microbiológicas e evolutivas das infecções bacterianas não espontâneas, em pacientes com cirrose hepática, internados no Hospital Militar, no período entre Março de 2018 e dezembro de 2020. Metodologia: Foi realizado um estudo transversal, descritivo e unicêntrico, que incluiu pacientes internados, com diagnóstico de cirrose hepática, que apresentavam infecção bacteriana não vinculada à hipertensão portal na admissão ou durante a internação. Os dados foram analisados ​​por meio de distribuição de frequência e medidas de resumo para as diferentes variáveis. A incidência de infecções bacterianas não espontâneas foi calculada com base na população total de pacientes cirróticos admitidos nesse período. Do total de cirróticos admitidos, 17,5% apresentavam infecção bacteriana não ligada à hipertensão portal, com média de idade de 61 anos, sendo 70% homens. A principal etiologia da cirrose foi alcoólica. A grande maioria dos pacientes (95%) apresentava doença hepática em estágio avançado (60% Child-Pugh estágio B e 35% estágio C), com média de MELD-Na de 21. A infecção mais frequente foi a do trato urinário (50%), seguida de pneumonia aguda (20%), infecções de pele e tecidos moles (10%) e colangite aguda (10%). Os microrganismos mais prevalentes foram bacilos gram negativos como Klebsiella pneumoniae e Escherichia coli. 40% dos pacientes apresentavam insuficiência hepática aguda-crônica no momento da admissão e outros 5% a desenvolveram durante a evolução. Desse grupo de pacientes, 20% morreram durante a internação. Conclusões: O presente estudo constitui uma aproximação ao conhecimento das infecções não espontâneas em pacientes cirróticos, sendo necessário o desenvolvimento de estudos com maior número de pacientes a fim de estabelecer uma associação estatisticamente significativa entre a presença de infecção bacteriana e o desenvolvimento de quadro agudo de insuficiência hepática crônica, e a partir disso com mortalidade a curto prazo.

ABSTRACT

Resumen Introducción: la enfermedad de Wilson es una enfermedad heterogénea causada por mutaciones en el gen ATP7B. La presentación clínica es variable, en fenotipos hepáticos y neuropsiquiátricos. El objetivo de este estudio es describir una cohorte retrospectiva de pacientes. Materiales y métodos: estudio retrospectivo descriptivo de pacientes atendidos en el Hospital Pablo Tobón Uribe desde enero de 2004 a septiembre de 2017. Resultados: se reportaron 27 pacientes, 17 hombres y 10 mujeres. El tiempo de seguimiento medio fue de 2,18 años, el 40% presentó síntomas neurológicos; el 29%, psiquiátricos; y el 85%, alteración hepática. En el laboratorio, el 85% presentó ceruloplasmina baja; 55%, cobre urinario alto; en casos con biopsia hepática, 7 tenían depósito de cobre en coloraciones especiales. En neuroimágenes, el 84% presentó hallazgos sugestivos de enfermedad de Wilson y en 3 casos se documentó una mutación genética patogénica. Durante el seguimiento, el 51% mejoró clínica o bioquímicamente, el 11% se mantuvo estable y el 18% se deterioró. El 88% de los casos sobrevivió al final del seguimiento. Conclusiones: este estudio es la cohorte retrospectiva más grande de Colombia. Los resultados son base para nuevos estudios poblacionales buscando de manera activa la enfermedad para documentarla en su fase preclínica y, de este modo, impactar en el pronóstico.


Abstract Introduction: Wilson's disease is a heterogeneous disorder caused by mutations in the ATP7B gene. Its clinical presentation is variable in hepatic and neuropsychiatric phenotypes. The aim of this study is to describe a retrospective cohort of patients. Materials and methods: A descriptive retrospective study was carried out in patients treated at the Hospital Pablo Tobón Uribe from January 2004 to September 2017. Results: 27 patients were reported, 17 men and 10 women. The mean follow-up time was 2.18 years. 40% of the patients had neurological symptoms, 29% psychiatric symptoms, and 85% hepatic impairment. Lab tests showed that 85% had low ceruloplasmin and 55% had increased urinary copper. In cases that underwent liver biopsy, 7 had special copper colorations. Neuroimaging revealed that 84% had findings suggestive of Wilson's disease and a pathogenic genetic mutation was documented in 3 cases. During follow-up, 51% improved clinically or biochemically, 11% remained stable, and 18% deteriorated. 88% of cases survived at the end of follow-up. Conclusions: This study is the largest retrospective cohort carried out in Colombia. The results are the basis for new population-based studies actively seeking this disease to describe its preclinical development and thus impact prognosis.

ABSTRACT

Introducción: La insuficiencia hepática aguda es una entidad de origen multifactorial, que se presenta en niños previamente sanos y tiene repercusión directa en las funciones de síntesis, coagulación y depuración. Objetivo: Caracterizar niños con insuficiencia hepática aguda según variables clínicas y humorales. Métodos: Se realizó un estudio retrospectivo y descriptivo de 19 pacientes con el diagnóstico de insuficiencia hepática aguda, atendidos en la Unidad de Cuidados Intensivos Pediátricos del Hospital Docente Infantil Sur de Santiago de Cuba, desde abril de 1998 hasta igual mes de 2018, para lo cual se emplearon métodos teóricos y estadísticos. Resultados: En la casuística predominó el sexo femenino (57,9 %), la mediana de la edad fue de 5 años y la infección constituyó la causa más común (73,7 %). Los virus hepatotrópicos como el de la hepatitis A resultaron los más frecuentes. Las complicaciones de mayor observancia fueron la alcalosis respiratoria (63,1 %), la disfunción multiorgánica (42,1 %) y la encefalopatía hepática (31,6 %). Las cifras bajas de colesterol y el tiempo de protrombina mayor de 20 segundos se asociaron a una mayor letalidad. Conclusiones: En los pacientes menores de un año los virus no hepatotrópicos constituyeron el origen más frecuente de dicha enfermedad.


Introduction: The acute liver failure is an entity of multifactorial origin that is presented in previously healthy children and has direct repercussion in the synthesis, clotting and purification functions. Objective: To characterize children with acute liver failure according to clinical and humoral variables. Methods: A retrospective and descriptive study of 19 patients with diagnosis of acute liver failure was carried out, they were assisted in the Pediatric Intensive Cares Unit of the Southern Children Hospital in Santiago de Cuba, from April, 1998 to the same month in 2018, for which theoretical and statistical methods were used. Results: In the case material there was a prevalence of the female sex (57.9 %), the mean age was 5 years and the infection constituted the most common cause (73.7 %). The hepatotropic virus as the hepatitis A were the most frequent. The complications of more observance were the respiratory alkalosis (63.1 %), the multiorganic dysfunction (42.1 %) and the liver brain disease (31.6 %). The low figures of cholesterol and the prothrombin time higher than 20 seconds were associated with a greater lethality. Conclusions: In the patients younger than one year the non hepatotropic virus constituted the most frequent origin in this disease.

ABSTRACT

Resumen: La insuficiencia hepática aguda es una enfermedad poco común pero que amenaza la vida y afecta con mayor frecuencia a pacientes que no tienen enfermedades preexistentes del hígado. El paracetamol (acetaminofén) es uno de los medicamentos analgésicos-antipiréticos prescritos con más frecuencia por los médicos y automedicados por las personas, cuyos efectos adversos son desde molestias leves hasta efectos adversos letales, que no necesariamente requieren la dosis tóxica para causar tales efectos graves. No es sorprendente que el paracetamol sigue siendo causa importante de sobredosis: desde intoxicaciones intencionadas (suicida) y no intencionadas (consumo crónico), cuyos efectos graves van desde la insuficiencia hepática fulminante relacionada con sobredosis hasta la muerte; la mitad de estos episodios se atribuyen al paracetamol y estos casos parecen estar aumentando cada vez más debido a su fácil acceso y venta libre. El objetivo de este artículo es comunicar un caso y revisar la bibliografía al respecto.


Abstract: Acute liver failure is a rare disease but life-threatening, and occurs more frequently in patients without preexisting liver disease. Paracetamol (acetaminophen) is one of the analgesic-antipyretic drugs most frequently prescribed by physicians and self- medicated by people, whose adverse effects are mild discomfort and even lethal side effects that do not necessarily require the toxic dose to cause such serious effects. Not surprisingly, acetaminophen remains a major cause of overdose: from intentional poisoning (suicide) and unintentional (chronic use), whose major effects are ranging from fulminant hepatic failure related to overdose to death; half of these episodes are attributable to paracetamol, and these cases seem to be increasing more and more, because of its easy access and free sale. The aim of this paper is to present a case report and a literature review.

ABSTRACT

La disfunción hepática postoperatoria del remanente hepático que ocurre en pacientes sometidos a grandes resecciones hepáticas, es un problema complejo y temido, dado su pronóstico incierto. La asociación de partición hepática y ligadura portal para hepatectomía por etapas (ALPPS), es un enfoque novedoso para pacientes portadores de enfermedad hepática oncológica que anteriormente eran considerados "no resecables". El procedimiento se realiza en dos etapas. La primera, comprende la ligadura de la rama derecha de la vena porta. Luego, se realiza la transección del parénquima hepático; incluyendo o no, la sección y ligadura de la vena hepática media. A continuación se empaqueta el hígado tumoral en una bolsa de polietileno y el abdomen es cerrado. La segunda etapa, se realiza 7 a 15 días después. Una vez abierto el abdomen, se retira la bolsa de polietileno; se ligan y seccionan la arteria, el conducto biliar y la vena hepática derechos; y se elimina el hígado tumoral. Pueden instalarse drenes y se procede al cierre de la laparotomía. La técnica ALPPS puede permitir entonces, la resección curativa de hígados tumorales en pacientes con lesiones considerados previamente como no resecables. El objetivo de este artículo fue describir las indicaciones y aspectos técnicos del ALPPS a propósito del primer caso realizado en nuestra ciudad, en una paciente de 47 años con un cáncer de vesícula biliar avanzado y metástasis bilobares.


Postoperative hepatic malfunction subsequent to insufficiency of hepatic remnant is a complex and dire problem in patients subjected to large hepatic resections. The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), is a novel approach for oncology patients whose hepatic tumors were previously considered non-resectable. The technique is performed in two phases. The first one comprises the ligation of the right portal vein branch. Subsequently, a parenchymal transection is performed, including or not, the middle hepatic vein. A plastic bag is employed to cover the tumoral liver, and the abdomen is closed. The second one is performed at 7 to 15 days interval. After laparotomy, the plastic bag is removed. The right artery, bile duct and hepatic vein are sectioned and the tumoral liver is removed. Drain was placed at the resection surface, and the abdomen is closed. ALPPS can enable curative resection of hepatic metastasis in patients with tumors previously considered non-resectable. The aim of this manuscript was to describe the indications and technical aspects of ALPPS in relation to the first case carried out in our city, in a 47-year-old woman with advanced gallbladder cancer with bilobar metastases.

ABSTRACT

O presente estudo avaliou a autorregulação encefálica (ARE) em doentes com insuficiência hepática fulminante (IHF) antes e após transplante hepático. Foram avaliados 25 pacientes com diagnóstico de IHF, 17 foram avaliados antes e após o transplante hepático, sendo seis (24,0%) do sexo masculino e 19 (76,0%) feminino. A média de idade foi de 33,8 anos, que variou de 14 a 56 anos, com desvio padrão de 13,1 anos. A hemodinâmica encefálica foi avaliada pela velocidade de fluxo sanguíneo encefálico (VFSE) nas artérias cerebrais médias e artéria basilar (AB), que usou o ultrassom Doppler transcraniano (DTC), dispositivo de dois canais, com transdutores de 2 mega Hertz (MHz). A autorregulação encefálica foi mensurada pelo índice de autorregulação (IARE) estática que leva em conta os efeitos do aumento da pressão arterial média (PAM) sobre a VFSE. Para isso, promoveu-se o aumento da PAM (20 mmHg a 30 mmHg) com infusão de noradrenalina.. Ao se avaliar o IARE considerando a velocidade de fluxo sanguíneo em quatro momentos (pré-transplante, 1°, 2° e 3° dia após o transplante), observou-se que houve diferença estatística em artéria cerebral média (ACM) à direita (p=0,008), esquerda (p=0,007), máxima (p=0,005), e AB (p=0,006); assim como na análise em cada tempo do IARE, observou-se diferença estatística em ACM à direita (p=0,012), esquerda (p=0,009), máxima (p=0,006), e AB (p=0,011). A análise categórica do IARE na artéria cerebral média e basilar descreveu que a maioria dos doentes reestabeleceu a AR no 2° dia em ACM e 3° na AB (índice > 0,6), enquanto com o índice > 0,8 em ambas as artérias a ARE reestabeleceu no 2° dia. As variáveis sistêmicas como pressão parcial de CO2 e hemoglobina nos tempos da avaliação não apresentaram diferença estatística p=0,100 e p=0,093 respectivamente. Os resultados obtidos apontam para o comprometimento da ARE antes e após transplante hepático, tanto em circulação anterior como posterior, e que tende a ser reestabelecido entre 48...


This study evaluated cerebral autoregulation in patients with fulminant hepatic failure (FHF) before and after liver transplantation. A total of 25 patients comprising six (24.0%) males and 19 (76.0%) females with FHF were evaluated. Seventeen patients were evaluated both before and after liver transplantation. Mean age of the patients was 33.8 years, with a range of 14-56 years and standard deviation of 13.1 years. Brain hemodynamics was assessed by cerebral blood flow velocity in the middle cerebral arteries (MCA) and basilar artery (BA) using transcranial Doppler ultrasound on a two-channel device with 2 MHz transducers. Cerebral autoregulation was measured by static cerebral autoregulation index (SCAI), which accounts for the effects of increase in mean arterial blood pressure (ABP) on cerebral blood flow velocity. An increase in ABP (20 mmHg to 30 mmHg) was induced with norepinephrine infusion. Evaluation of SCAI based on blood flow velocity (BVF) at four timepoints (pre-transplant and on 1st, 2nd and 3rd days post-transplant) revealed a statistical difference in the MCA right (p = 0.008) left (p = 0.007), maximum (p = 0.005) and the BA (p = 0.006). In addition, analysis by timepoint showed a statistical difference in MCA (p = 0.012), left (p = 0.009), maximum (p = 0.006) and in the BA (p = 0.011). Categorical analysis of autoregulation in the MCA and BA showed that most patients reestablished autoregulation in the MCA on the 2nd day post-transplant and in the BA (index > 0.6) on the 3rd day, while autoregulation was reestablished in both arteries (index > 0.8) on the 2nd day. On the assessment by timepoint, the systemic variables CO2 partial pressure and hemoglobin showed no statistically significant differences (p = 0.100 and p = 0.093, respectively). The results reveal impaired SCAI before and after liver transplantation, both in anterior and posterior circulation, with a tendency to reestablish at 48 to72 hours. The findings of this study can help...

ABSTRACT

Se reporta el caso de una mujer de 37 años de edad sin antecedentes relevantes, que consulta por cuadro febril ictérico asociado con alteración hepática importante con patrón necroinflamatorio, se documenta hepatitis viral B y presenta una evolución tórpida rápida hasta la muerte. De esta forma, se exponen los posibles factores que influyen en la progresión hacia la insuficiencia hepática fulminante (IHF) descritos en la literatura.


We report the case of a 37 year old woman who came to the hospital because of jaundice and a fever. Her symptoms were associated with significant liver impairment and a necroinflammatory pattern due to viral hepatitis B although she had no relevant medical history. Her symptoms developed rapidly until death. We present the factors that may have influenced her progression to fulminant liver failure as described in the literature.

ABSTRACT

BACKGROUND: Acute liver failure is associated with a high mortality rate and the main purposes of treatment are to prevent cerebral edema and infections, which often are responsible for patient death. The orthotopic liver transplantation is the gold standard treatment and improves the 1-year survival. AIM: To describe an alternative technique to auxiliary liver transplant on acute liver failure. METHOD: Was performed whole auxiliary liver transplantation as an alternative technique for a partial auxiliary liver transplantation using a whole liver graft from a child removing the native right liver performed a right hepatectomy. The patient met the O´Grady´s criteria and the rational to indicate an auxiliary orthotopic liver transplantation was the acute classification without hemodynamic instability or renal failure in a patient with deterioration in consciousness. RESULTS: The procedure improved liver function and decreased intracranial hypertension in the postoperative period. CONCLUSION: This technique can overcome some postoperative complications that are associated with partial grafts. As far as is known, this is the first case of auxiliary orthotopic liver transplantation in Brazil. .


RACIONAL: A insuficiência hepática aguda está associada à alta taxa de mortalidade e os principais efeitos do tratamento são para evitar o edema cerebral e as infecções, que muitas vezes são responsáveis pela morte do paciente. O transplante hepático é o tratamento padrão-ouro e melhora a sobrevida de um ano. OBJETIVO: Descrever uma técnica alternativa para transplante de fígado auxiliar na insuficiência hepática aguda. MÉTODO: Transplante de fígado auxiliar devido à insuficiência hepática fulminante pela infecção pelo vírus da hepatite B. O paciente preencheu os critérios O´Grady e o racional para indicar o transplante de fígado auxiliar foi a hepatite aguda sem instabilidade hemodinâmica ou insuficiência renal em um paciente com deterioração da consciência. Foi realizado o transplante auxiliar de fígado com enxerto inteiro com uma técnica alternativa para transplante auxiliar parcial de fígado. RESULTADOS: O procedimento demonstrou melhora da função hepática e diminuição da hipertensão intracraniana no pós-operatório. CONCLUSÃO: Esta técnica é viável e pode superar algumas complicações pós-operatórias que estão associadas com enxertos parciais. Tanto quanto sabemos, este é o primeiro caso de transplante de fígado auxiliar descrito no Brasil. .

ABSTRACT

El objetivo de este estudio fue describir el perfil biológico y social del paciente pediátrico con trasplante hepático por insuficiencia hepática aguda (IHA) y la evolución postrasplante. Material y Método: trabajo retrospectivo, descriptivo y observacional, se revisaron la base de datos de 142 pacientes trasplantados por IHA desde 1992 al 2008. Se describieron los datos demográficos y sociales, indicaciones de trasplante, tipo de injerto utilizado, compatibilidad del grupo ABO, evolución pos trasplante (resultados primarios), complicaciones del trasplante y sobrevida. Resultados: El 51% de los casos de IHA fue asociado a la hepatitis infecciosa por virus A (HAV) y el 41% correspondió a las IHA indeterminadas. El 85% de la población trasplantada (120 casos) recibió un donante de tipo cadavérico (DC) y la compatibilidad de grupo ABO fue del 85%. Las complicaciones más frecuentes fueron: biliares 33 casos, infecciones bacterianas 20 casos y vasculares 13 casos. El rechazo agudo estuvo presente en 72 casos mientras que el rechazo crónico se diagnosticó en 7 casos. La sobrevida de la IHA al año del postrasplante fue del 80% y a los 5 y 10 años fue del 77%. La conciencia de enfermedad reflejada en el cumplimiento de las consignas médicos sociales estuvo presente en un 86,25%. El 70% de los padres de los niños trasplantados eran biológicos y el 52% de la población provino del área centro (Buenos Aires, Córdoba, Entre Ríos, y Santa Fe). La cobertura estuvo a cargo del estado en el 45% de la muestra (AU)


The aim of this study was to describe the social and biological profile of pediatric patients who undergo liver transplantation because of acute liver failure (ALF) and post-transplant outcome. Material and Methods: A retrospective, descriptive, and observational study was conducted. The database of 142 patients who underwent liver transplantation because of ALF between 1992 and 2008 was reviewed. Demographic and social features, indication for transplantation, type of graft used, ABO group compatibility, post-transplant outcome (primary results), complications of the transplantation and survival were evaluated. Results: ALF was associated with infectious hepatitis A (HAV) in 51% of the cases and with indeterminate ALF in 41%. Overall, 85% of the transplanted patients (120 cases) received a deceased donor (DD) organ and ABO group compatibility was 85%. Most common complications were: biliary in 33 cases, bacterial infections in 20 cases, and vascular in 13 cases. Acute rejection was observed in 72 cases while chronic rejection was diagnosed in seven cases. Oneyear post-transplant survival after ALF was 80%, while 5- and 10-year survival was 77%. Disease awareness expressed in compliance with medical and social indications was observed in 86%. Seventy percent of the parents of transplanted children were there biological parents and 52% of the population came from the central area of the country (Buenos Aires, Córdoba, Entre Ríos, y Santa Fe). Forty-five percent of the sample had public health care coverage (AU)

ABSTRACT

La hepatitis A (HA) presenta una evolución benigna, pero en ocasiones puede causar una insuficiencia hepática aguda con necesidad de trasplante. En 2003, en un consenso realizado en la Sociedad Argentina de Pediatría, se recomendó la incorporación de la vacuna contra la HA en el calendario nacional. Esto se concretó por decreto ministerial y se efectivizó a partir del 1 de junio de 2005, con la obligación de aplicar una dosis de la vacuna a todos los niños al año de edad. Desde entonces, se registró una disminución marcada de casos y no se documentaron cuadros de insuficiencia hepática aguda desde el año 2006. Los estudios de seguimiento mostraron, hasta el momento, una circulación viral baja y la persistencia de anticuerpos hasta los 5 años posteriores a su introducción.


Hepatitis A (HA) presents a benign evolution, but occasionally some patients develop a more severe disease. Previously to 2005 hepatitis A was an important cause of acute liver failure (ALF) and hepatic transplant. In 2003, a consensus in the Argentinian Pediatrics Society was done; it had just recommended the inclusion of the vaccine in the mandatory immunisation schedule. This was issued by the Health Ministery, and was applied on June 1st, 2005. The schedule was one dose at the age of one year of age. Since then, an important reduction of HA was registered, without any case of ALF since 2006. Follow-up studies so far showed low viral circulation and persistence of antibodies to 5 years later.

ABSTRACT

Introdução e objetivos: a insuficiência hepática aguda (IHA), apesar de rara, permanece como uma condição rapidamente progressiva e frequentemente fatal. A intoxicação por acetaminofen (APAP) induz necrose hepática maciça e frequentemente leva à morte por edema cerebral. Terapias celulares são de grande interesse como potenciais tratamentos para IHA. Neste projeto foi avaliado o potencial terapêutico das células mononucleares da medula óssea (CMMO) em um modelo experimental de IHA induzida por APAP em camundongos. Métodos: A IHA foi induzida em camundongos C57Bl/6, previamente submetidos à dieta alcoólica por três semanas, através da administração de APAP na dose de 300 mg/kg por via intraperitoneal. Após a indução da IHA, os camundongos foram transplantados, por via endovenosa, com 107 CMMO...


Introduction and objectives: a cute liver failure (IHA), although rare, remains a rapidly progressive and often fatal condition. Poisoning by acetaminophen (APAP) induces a massive hepatic necrosis and often leads to death by cerebral edema. Cell therapies are of great interest as potential treatments for IHA. In this project we evaluated the therapeutic potential of bone marrow mononuclear cells (BMC) in an experimental model of IHA induced by APAP in mice. Methods: The IHA was induced in C57BL/6 mice previously submitted to the alcohol diet for three weeks by the administration of APAP at a dose of 300 mg / kg, intraperitoneally. After induction of IHA, the mice were transplanted intravenously with 107 BMC...

ABSTRACT

A encefalopatia hepática (EH) é um distúrbio funcional do sistema nervoso central (SNC) associado à insufi ciência hepática, de fisiopatologia multifatorial e complexa. Devido aos avanços no conhecimento sobre o manejo da EH na cirrose e na insuficiência hepática aguda (IHA), a diretoria da Sociedade Brasileira de Hepatologia (SBH) promoveu uma reunião monotemática acerca da fi siopatologia, diagnóstico e tratamento da EH, abordando aspectos controversos relacionados ao tema. Com a utilização de sistemática da medicina baseada em evidências, foram abordados o manejo da EH e da hipertensão intracraniana na IHA, o manejo da EH episódica na cirrose, as controvérsias no manejo da EH e a abordagem da EH mínima. O objetivo desta revisão é resumir os principais tópicos discutidos na reunião monotemática e apresentar recomendações sobre o manejo da síndrome votadas pelo painel de expertos da SBH.


Hepatic encephalopathy (HE) is a functional disorder of the central nervous system (CNS) associated with liver failure, either end-stage chronic liver disease or fulminant hepatic failure. Its pathogenesis remains complex and poorly understood. In view of recent advances in the management of HE, the Brazilian Society of Hepatology endorsed a monothematic meetingregarding HE in order to gather experts in the to discuss related data and to draw evidence-based recommendations concerning: management of HE and intracranial hypertension in FHF, treatment of episodic HE in cirrhosis, controversies in the management of EH including difficult to treat cases and diagnostic and treatment challenges for minimal HE. The purpose of this review is to summarize the lectures and recommendations made by the panel of experts of the Brazilian Society of Hepatology.

ABSTRACT

A insuficiência hepática aguda grave (IHAG), embora seja uma entidade pouco frequente, possui letalidade que varia de 50% a 90 %, acometendo indivíduos, previamente hígidos, no que se concerne à função hepática. E caracterizada pela instalação súbita de perda das características fisiológicas dos hepatócitos, que costuma evoluir rapidamente, e está implicada no aparecimento da encefalopatia hepática, icterícia, hipoglicemia, alteracões da coagulação e insuficiência renal. A etiologia possui alta variabilidade geográfica. No Reino Unido e na América do Norte, a causa mais frequente é a intoxicação por paracetamol; no restante dos países predominam as hepatites virais, sobretudo a hepatite pelo vírus B. O tratamento da IHAG é feito em regime deUnidade de Terapia Intensiva, tendo no transplante hepático a modalidade terapêutica com melhores resultados. Considerando o comportamento agressivo e prognóstico reservado da IHAG, o cuidado a estes pacientes deve englobar a combinação da velha arte do cuidar hipocrático com a utilização dos recursos tecnológicos que a Medicina atual pode oferecer.


The severe acute liver failure (SALF), although a rare entity, whose mortality ranges from 50% to 90%, affects previously healthy individuals, in relation to liver function. It is characterized by a sudden loss of physiological characteristics of hepatocytes, which often change rapidly, and is implicated in the onset of hepatic encephalopathy, hypoglycemia, jaundice, changes in coagulation and renal failure. The etiology has high geographic variability. ln the UK and North America, the most frequent cause is paracetamol poisoning; in the remaining countries, the predominance is viral hepatitis, particularly by hepatitis B virus. Treatment of SALF is done on an intensive care unit and liver transplant is the treatment modality with better results. Considering the aggressive behavior and reserved prognosis of SALF, care to these patients should include a combination of the old Hippocratic art of care with the use of technological resources that current Medicine offers.

ABSTRACT

Intermação induzida por exercício é uma condição potencialmente fatal causada pela elevação extrema da temperatura corporal central. Envolvimento hepático leve a moderado afeta todos os pacientes e manifesta-se pela elevação das enzimas hepáticas. A ocorrência de falência hepática no curso da intermação por exercício é rara e tem prognóstico reservado. Relata-se um caso de insuficiência hepática fulminante em um homem de 36 anos após correr 8km em corrida de rua (corrida rústica) na cidade de Manaus (AM). O paciente desenvolveu insuficiência renal aguda, rabdomiólise e achados compatíveis com insuficiência hepática fulminante (elevação importante das aminotransferases, coagulopatia, letargia e episódios de confusão). As funções hepáticas e renais apresentaram melhora gradual e espontânea sem necessidade de diálise. Três meses após o paciente encontrava-se bem, com enzimas hepáticas normais e com retorno gradual à prática de esportes. Embora rara, a falência hepática aguda deve ser incluída nas complicações da intermação induzida por exercício, a qual pode ter resolução espontânea com medidas conservadoras.


Exercise-induced exertional heatstroke (EHS) is a potentially fatal disorder caused by extreme elevation of the core body temperature. Mild to moderate liver involvement affects nearly all patients and it is manifested by increase of the serum liver enzymes. Liver failure occurring as a component of exertional heatstroke is rare and carries a poor prognosis. A case of acute liver failure in a healthy 36 year-old man after participation in an 8-km race in Manaus, located near the Amazon Tropical Forest in Brazil, is reported here. The patient presented renal failure, severe rhabdomyolysis and findings of fulminant hepatic failure (very high aminotransferases levels, elevated international normalized ratio (INR), lethargy and episodes of confusion). Hepatic and renal functions improved spontaneously with conservative measures and he was discharged within eight days. Three months later he was completely asymptomatic and gradually running again. Although rare, acute liver failure should be included in the complications associated with exertional heatstroke. Conservative management may be effective in some patients with this kind of acute liver failure.

ABSTRACT

Se presenta una paciente con hipertiroidismo por una enfermedad autoinmune del tiroides que luego de 2 semanas de tratamiento con propiltiouracilo comenzó a presentar un rash generalizado acompañado de fiebre que evolucionó rápidamente a una insuficiencia hepática aguda, fallo multiorgánico y muerte. Se demostró en la necropsia la necrosis masiva del hígado. Se revisaron las afectaciones hepáticas inducidas por reacción idiosincrásicas a medicamentos. Se recomienda instruir a los pacientes sobre posibles síntomas de hepatotoxicidad, indicar pruebas hepáticas periódicamente a los hipertiroideos tratados con antitiroideos y evitar el uso simultáneo de fenobarbital.


The case of a patient with hyperthyroidism due to an autoimmune disease of the thyroid glands that after two weeks of treatment with propylthiouracil presented a systemic rash accompanied with fever evolving quickly to an acute hepatic failure, multiorgan failure, and death, was presenetd. A massive liver necrosis was confirmed in the necropsy. The hepatic affectations induced by idiosyncratic drug reaction were reviewed. We suggest to instruct these patients on the possible symptoms of hepatotoxicity, to indicate periodical hepatic tests to hyperthyroid patients treated with antithyroid agents, and to avoid the simultaneous use of phenobarbital.

ABSTRACT

La intoxicación por fósforo blanco es una patología que es frecuente en festividades navideñas y de fin de año debido al uso de la pólvora recreativa como las martinicas, elementos de fácil acceso para los niños, principalmente lactantes y preescolares, los cuales sin medir consecuencias se convierten en víctimas de intoxicaciones al llevarse estos elementos a la boca y en ocasiones ingerirlos. En esta revisión se describe el caso de una menor intoxicada al ingerir fósforo blanco, con el objetivo de dar a conocer los efectos de este tóxico y advertir a los adultos a cargo acerca de la letalidad de esta patología, con el propósito de derivar a partir de esta revisión políticas encaminadas principalmente hacia prevención del evento. Se describe el caso de una niña de 2 años de edad que ingiere cuatro martinicas, presentando todos los efectos nocivos que ocasiona este tóxico a nivel hepático; la paciente recibió medidas iniciales las cuales fueron insuficientes por lo que tuvo que ser llevada a la unidad de cuidados intensivos con evolución favorable que hasta el momento no ha requerido transplante.


White phosphorus’ poisoning is a frequent pathology during holydays and New Year’s Eve. Fire works such as “martinicas”, are accessible for children – especially toddlers and preschoolers – who can have poisoning when they bring these elements to their mouths and ingest them, by accident. This work describes the case of a minor who was poisoned when she ingested white phosphorus. Our purpose is to show white phosphorus’ toxic effects and warn adults about this lethal pathology, in order to create policies directed towards its prevention. A two years old girl ingested four “martinicas”, presenting with hepatotoxicity. The patient needed an ntensive care unit admission with a favorable outcome and without requiring liver transplant.

ABSTRACT

PURPOSE: To evaluate the effect of laser beam on remanescent liver after partial hepatectomy 90 percent. METHODS: Wistar rats, (N= 42), were divided into six groups with seven specimens each. The partial hepatectomy (HP) was performed in all animals through exeresis of approximately 90 percent of the liver parenchyma. The animals from groups HP and Laser application, HPL24, HPL48 and HPL72 undertook laser irradiation carried out through application (dose of 22.5 J/cm²) in five different sites in the remanescent liver. The rats were then sacrificed 24, 48 and 72hours after HP procedure, for the liver regeneration analysis,using the Proliferating Cell Nuclear Antigen (PCNA),and for dosage of serum aminotransferases. RESULTS: Were demonstrated an increase of the serum levels of alanine aminotransferase for the group of 24 hours and a decrease for the group of 72 hours exposed to laser. The index of marked cells had a considerable more improvement for the group of 72 hours exposed in laser compared to other groups. CONCLUSION: Laser did not cause hepatic injuries additional to the partial hepatectomy and perhaps led to a benefit by stimulating the proliferative activity.


OBJETIVO: Avaliar o efeito da luz laser em remanescentes hepáticos após hepatectomia a 90 por cento. MÉTODOS: Aplicou-se luz laser com comprimento de onda de 660 nm e potência de 30 mw, por 30 segundos, na dose de 22,5 J/cm² em cada um deles, repetidos em cinco pontos do fígado remanescente, após realizada a hepatectomia a 90 por cento. Os animais foram sacrificados para análise do fígado, contagem de hepatócitos em proliferação (Proliferating Cell Nuclear Antigen -PCNA), e coleta de sangue para dosagem serica das aminotransferases, após 24, 48 e 72 horas. RESULTADO: O índice de células marcadas teve significativo aumento no grupo de 72 horas irradiados com laser. CONCLUSÃO: A análise dos resultados demonstrou que o laser não causou lesões hepáticas adicionais à hepatectomia parcial e estimulou a atividade proliferativa hepatocelular.

ABSTRACT

O efeito fotobioestimulador do laser de baixa potência e uma modalidade terapêutica que progressivamente vem crescendo. Presume-se que este conduza a alterações conformacionais na estrutura dos citocromos dos hepatócitos, expressando um aumento do metabolismo energético do fígado de ratos submetidos à hepatectomia. As perspectivas de aplicação do laser na insuficiência hepática aguda motivam pesquisas com intuito de aumentar as opções terapêuticas para essa doença. 0 objetivo desse trabalho foi avaliar os efeitos da irradiação a laser, nos ratos submetidos a hepatectomia a 90%. O laser foi aplicado em cinco pontos do fígado remanescente, por 30 segundos em cada um deles, com comprimento de onda de 660 nm e intensidade 30 mW. Os animais foram sacrificados após 24, 48 e 72 horas para coleta de sangue sendo realizado as dosagens bioquímicas de bilirrubina total e frações; da alanina-aminotransferase; aspartato-aminotransferase; fosfatase alcalina e desidrogenase lática e análise do fígado através de imuno-histoquímica utilizando o Antígeno Nuclear de Proliferação Celular. Nos grupos irradiados com laser os resultados mostraram diminuição nos níveis de bilirrubina direta nos grupos de 48 e 72 horas; acréscimo do nível sérico de alanina-aminotransferase no grupo de 24 horas e decréscimo no grupo de 72 horas e 0 aumento do índice de células marcadas no grupo de 72 horas. A análise dos resultados demonstrou que o laser não causou lesões hepáticas adicionais a ressecção e estimulou a atividade proliferativa


The photobiostimulator effect of laser of low power is a therapeutic modality which is growing progressively. It is assumed that this effect conducts conformational alterations in the structure of the cytochrome of hepatocytes, expressing an increase in the energetic metabolism of the liver from rats which were undergone hepatectomy. The perspectives of application from laser in the an acute hepatic failure takes to researches with the objective of improving the therapeutic options to this disease. The objective of this survey was to value the laser effect in rats which were undergone hepatectomy in 90%. The laser was applied in five places of remainder liver for 30 seconds each one, with 660 nm in length of wave and 30 mW of intensity. The animais were sacrificed after 24 hours, 48 hours and 72 hours to analysis of the blood sample through of biochemical dosages of total bilirubin and fractions of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase and an analysis of the Iiver through an imunohistochemical assessment using the Proliferating Cell Nuclear Antigen. The results of the groups of 48 hours and 72 hours who were exposed in laser showed a decrease in the direct bilirubin levels, an increase in the serical levels of alanine aminotransferase in group of 24 hours and a decrease in group of 72 hours and in the group of 72 hours also happened an increase in the appearance of marked cells. The analysis of the results showed that the laser did not cause hepatic injuries additional to dissection and brought the benefit of stimulating the proliferative activity
