ABSTRACT

Introduction: Liver biopsy is an invasive procedure with a minimal rate of associated complications, which represents a highly useful strategy for the diagnosis of pathologies in the liver, when the etiology cannot be clarified by non-invasive techniques. It provides information that allows determining the progression and prognosis of liver diseases. Objectives: To evaluate the main etiology causes of liver disease in patients undergoing liver biopsy. Material and Methods: Review of the clinical record of 61 patients who underwent this procedure between 2018 and 2020 at the Hernán Henríquez Aravena hospital, demographic variables, diagnosis that motivates its performance, and associated complications. Results: Average age 58 years, of this 66% were female and 34% were male. The diagnoses that motivated this procedure were: autoimmune hepatitis, liver Tumors, and chronic liver damage of unknown etiology. 100% of the case had a satisfactory sample for the analysis and clarification of the cause of liver disease. 91% did not present complications and of the 8% associated with complications, pain was the most common. Conclusion: Liver biopsy is an effective method that allowed establishing etiology, confirming diagnosis suspicions, and evaluating the progression of liver disease with a low rate of complications.


Introducción: La biopsia hepática es un procedimiento invasivo con una tasa mínima de complicaciones asociadas, que representa una estrategia de gran utilidad para el diagnóstico de patologías a nivel del hígado, cuando a través de técnicas no invasivas no se logra esclarecer la etiología. Además, entrega información que permite determinar la progresión y pronóstico de enfermedades hepáticas. Objetivos: Evaluar las principales causas etiológicas de hepatopatías en los pacientes sometidos a biopsia hepática. Material y Método: Revisión de fichas clínicas de 61 pacientes sometidos a este procedimiento entre el año 2018 y 2020 en el hospital Hernán Henríquez Aravena, se analizaron variables demográficas, diagnóstico que motiva su realización, y complicaciones asociadas. Resultados: Edad promedio: 58 años de estos: 66% eran del sexo femenino y 34% al sexo masculino. De los diagnósticos que motivaron a la realización de la biopsia fuero: hepatitis autoinmune, tumores hepáticos y daño hepático crónico de etiología no precisada. El 100% de los casos tuvo una muestra satisfactoria para el análisis y esclarecer la causa de la hepatopatía. El 91% no presentó complicaciones y del 8% de las complicaciones presentadas, el dolor fue la principalmente descrita. Conclusiones: La biopsia hepática es un método eficaz que permitió establecer etiología, confirmar sospechas diagnósticas y evaluar progresión de enfermedades hepáticas con una baja tasa de complicación.

ABSTRACT

RESUMEN Introducción: la cirrosis hepática de etiología viral representa un impactante problema de salud a nivel mundial, no solo por su elevada tasa de prevalencia, sino por los costos generados en la atención médica. Objetivos: determinar el comportamiento de los pacientes cirróticos, de etiología viral, en la provincia de Matanzas. Materiales y métodos: se realizó un estudio descriptivo-retrospectivo en 47 pacientes con cirrosis hepática de etiología viral, atendidos en el Servicio de Gastroenterología del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas, de enero de 2016 a enero de 2018. Los resultados de las variables analizadas se expusieron en tablas de doble entrada. Resultados: el 68,1 % de los pacientes correspondió a cirrosis por virus C. Predominaron los mayores de 50 años, con carga viral entre 4-6,9 log10, y atendidos en régimen ambulatorio. En el 57,4 % se detectaron signos endoscópicos de hipertensión portal, que se corroboraron en el doppler hepático. La ascitis asociada a diferentes sepsis fueron las complicaciones más registradas. El 55,4 % fue clasificado como Child-Pugh A, y el 76,6 % en etapa clínica compensada. Conclusiones: el diagnóstico y seguimiento de la cirrosis hepática viral sigue siendo un verdadero reto para la comunidad médica. De ahí los esfuerzos que han de realizarse para su control desde las fases compensadas, para retardar la aparición de complicaciones (AU).


ABSTRACT Introduction: viral etiology liver cirrhosis is an impacting health problem around the world, not only because of its high prevalence rate but also because of the costs generated by its medical care. Objective: to determine the behavior of the patients with viral etiology liver cirrhosis in the province of Matanzas. Materials and methods: a descriptive-retrospective study was carried out in 47 patients with viral etiology liver cirrhosis treated in the service of Gastroenterology of the Hospital "Comandante Faustino Perez" of Matanzas, from January 2016 to January 2018. The results of the analyzed variables were shown in double-entry tables. Results: 68.1% of the patients presented cirrhosis caused by C virus, Patients elder 50 years old predominated, with 4-6.9 log10, treated in ambulatory regimen. Endoscopic signs of portal hypertension were found in 57.4%. It was corroborated with liver Doppler. Ascites associated to different sepsis were the most frequently registered complications. 55.4% were classified as Child-Pugh A, and 76.6% were in compensated clinical stage. Conclusions: viral liver cirrhosis diagnosis and follow-up is still a true challenge for the medical community, and hence the efforts that should be made to control it from the compensated stages to delay the appearance of complications (AU).

ABSTRACT

Introducción. Las enfermedades autoinmunes del hígado son un grupo de patologías caracterizadas por una respuesta autoinmune contra los hepatocitos y/o el epitelio biliar. Sus manifestaciones clínicas son variadas, con alteraciones en las pruebas de función hepática y presencia de autoanticuerpos. Metodología. Estudio observacional descriptivo con 101 pacientes atendidos en el Hospital Universitario de La Samaritana de Bogotá D.C., entre enero a diciembre de 2019, con los diagnósticos de hepatitis autoinmune, colangitis biliar primaria, colangitis esclerosante primaria y síndrome de sobreposición. Se evaluaron los parámetros clínicos y de laboratorio, con el fin de caracterizar su frecuencia en estas patologías, debido a la importancia de un diagnóstico precoz. Resultados. Se encontraron 54 casos de hepatitis autoinmune, 19 casos de colangitis biliar primaria, 4 casos de colangitis esclerosante primaria y 24 casos de síndrome de sobreposición. El 81% fueron mujeres y la edad promedio fue de 55 años. El 39% de los pacientes tenían cirrosis. En general, los resultados se ajustaron a lo descrito internacionalmente, como es el predominio en mujeres y la comorbilidad autoinmune. Conclusión. Los hallazgos indican que cualquier alteración del perfil bioquímico hepático debe ser considerado, y se debe descartar la presencia de hepatopatías autoinmunes para diagnosticarlas de manera precoz, evitando que lleguen a cirrosis y sus complicaciones, con la necesidad de un trasplante hepático como única alternativa terapéutica.


Introduction. Autoimmune liver diseases are a group of pathologies characterized by an autoimmune response against hepatocytes and/or the biliary epithelium. Their clinical manifestations are varied, with alterations in liver function tests and the presence of autoantibodies. Methodology. Descriptive study with 101 patients who attended at the Hospital Universitario de La Samaritana in Bogota D.C., between January and December 2019, with the diagnoses of autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis and overlap syndrome. Clinical and laboratory parameters were evaluated in order to characterize their frequency in these pathologies, due to the importance of an early diagnosis. Results. There were 54 cases of autoimmune hepatitis, 19 cases of primary biliary cholangitis, 4 cases of primary sclerosing cholangitis, and 24 cases of overlap syndrome. Of all patients, 81% were women, the average age was 55 years, and 39% had cirrhosis. In general, the findings were consistent with what has been described worldwide, such as a higher prevalence in women and autoimmune comorbidity. Conclusion. The findings indicate that any alteration in the liver biochemical profile should be considered to rule out an autoimmune liver disease for an early diagnosis, avoiding the possibility of cirrhosis and its complications, with the need for a liver transplant as the only therapeutic alternative.

ABSTRACT

RESUMEN La microbiota se refiere al conjunto de todos los de microorganismos que se localizan de manera normal en distintos sitios de los cuerpos de los seres vivos pluricelulares, tales como el cuerpo humano. Las modificaciones del eje intestino-hígado se ha convertido en la actualidad en un grave problema científico al haberse encontrado en diversas investigaciones, que esta microbiota está relacionada con el daño hepático con independencia de la causa de la lesión hepática. Se realizó una revisión sistemática sobre las implicaciones demamicrobiota intestinal en las enfermedades hepáticas. Se realizó una revisión de artículos científicos publicados entre 2012 y 2018 en diversas bases de datos en línea. Se presenta el conocimiento existente hasta el momento sobre la microbiota intestinal en pacientes portadores de enfermedades hepáticas, con hincapié en las hepatitis C y la cirrosis hepática. La composición de microbiota de intestino estuvo asociada con el perfil inflamatorio y marcadores de fibrosis hepática, las que mejoraron con el tratamiento de antivirales de acción directa aunque las medidas de permeabilidad intestinal e inflamación permanecían inalteradas. Se reporta mejoría de los pacientes portadores de hepatitis viral tipo C, con antivirales de acción directa la cual estuvo asociada con modificaciones de la microbiota intestinal, que se correlacionó con mejoría en la fibrosis e inflamación hepática, los avances en este campo abren nuevas perspectivas en la biomedicina (AU).


SUMMARY Microbiota refers to the whole of microorganisms located in a normal way in different places of the bodies of pluricelular living beings, like the human body. The modifications of the axis intestine-liver have become a serious scientific problem, because in different researches researchers have found that this microbiota is related to hepatic damage depending on the cause of this hepatic lesion. To carry out a systematic review on the implication of intestinal macrobiota in liver diseases. The scientific articles published in the period 2012-2018 in different databases on line were reviewed. A total of 26 bibliographic sources were used, original articles and reviews. The authors present knowledge existent up to the moment on intestinal microbiota in patients who have liver diseases, making emphasis on hepatitis C and hepatic cirrhosis. The composition of the intestine microbiota was associated to an inflammatory and markers of hepatic fibrosis that improved with the treatment of direct action antivirals although the measures of intestinal permeability and inflammation remained inalterably. It is reported an improvement of patients carriers of viral hepatitis type C with the use direct action retrovirals, what was linked to modifications in the intestinal microbiota, and correlated to an improvement of fibrosis and liver inflammation; the advances obtained in this field open new perspectives in biomedicine (AU).

ABSTRACT

Resumen: SARS-CoV-2 es un virus de alta estabilidad ambiental. Es principalmente un patógeno respiratorio que también afecta el tracto gastrointestinal. El receptor ACE2 es el principal receptor de SARS- CoV-2, hay evidencia de su elevada presencia en intestino, colon y colangiocitos; igualmente se en cuentra expresado en hepatocitos pero en menor proporción. SARS-CoV-2 tiene un tropismo gas trointestinal que explica los síntomas digestivos y la diseminación viral en deposiciones. Las caracte rísticas de SARS-CoV-2 incluyen a la proteína S (Spike o Espícula) que se une de forma muy estable al receptor ACE2. La infección por SARS-CoV-2 produce disbiosis y alteraciones en el eje pulmón- intestino. A nivel intestinal y hepático produce una respuesta Linfocitos T evidente y una respuesta de citocinas que producirían daño intestinal inflamatorio. Las manifestaciones a nivel intestinal en orden de frecuencia son pérdida de apetito, diarrea, náuseas, vómitos y dolor abdominal. Éste último podría ser un marcador de gravedad. En niños la diarrea es habitualmente leve y autolimitada. A nivel hepático la hipertransaminasemia ocurre en 40-60% de los pacientes graves. SARS-CoV-2 puede per manecer en deposiciones un tiempo más prolongado que en secreciones respiratorias, este hallazgo influiría en la diseminación de enfermedad. En esta revisión se destaca la importancia de efectuar un reconocimiento precoz de las manifestaciones gastrointestinales y hepáticas, aumentar el índice de sospecha, efectuar un diagnóstico oportuno y reconocer eventuales complicaciones de la enferme dad. La potencial transmisión fecal oral puede influir en la diseminación de enfermedad. Reconocer este hallazgo es importante para definir aislamiento.


Abstract: SARS-CoV-2 is a high environmental stable virus. It is predominantly a respiratory pathogen that also affects the gastrointestinal tract. The ACE 2 receptor is the main receptor of SARS-CoV-2, with evidence of its high presence in the intestine, colon and cholangiocytes, and, in smaller proportion, in hepatocytes. SARS-CoV-2 has a gastrointestinal tropism that explains digestive symptoms and viral spread in stools. The characteristics of this virus include the S (Spike) protein that binds very stably to the ACE-2 receptor and, at the same time, SARS-CoV-2 produces dysbiosis and alterations in the gut-lung axis. It produces a clear T-cell response and a cytokines storm in the intestine and liver that would produce inflammatory bowel damage. Intestinal manifestations by order of frequency are loss of appetite, diarrhea, nausea and vomiting, and abdominal pain, where the latter could be a severity marker. In children, diarrhea is the most frequent symptom, usually mild and self-limiting. In the liver, hypertransaminasemia occurs in severe patients ranging from 40 to 60%. SARS-CoV-2 can re main in stools longer than in respiratory secretions, which would influence the spread of disease. This article highlights the importance of an early diagnosis of gastrointestinal and hepatic manifestations, increase the index of suspicion, make a timely diagnosis, and recognize eventual complications of the disease. The potential oral-fecal route of transmission may influence the disease spread. Recognizing this finding is important to define isolation.

ABSTRACT

RESUMEN Introducción: el embarazo supone cambios en la fisiología de la mujer. Estos cambios pueden llevar a la aparición de enfermedades que afectan el hígado como: síndrome de HELLP, colestasis gravídica intrahepática, esteatosis hepática aguda del embarazo, entre otras, que pueden repercutir en el curso de la gestación. Material y métodos: se realizó un estudio observacional, descriptivo, retrospectivo de corte transversal en 52 gestantes que fueron valoradas en gastroenterología por sospecha de hepatopatías durante el embarazo en el año 2018, que constituyeron el universo de estudio, con el objetivo de determinar el comportamiento de las hepatopatías durante la gestación en las embarazadas valoradas por el servicio de Gastroenterología del Hospital Universitario "Comandante Faustino Pérez Hernández" de Matanzas. Se estudiaron las variables: trimestre gestacional, síntomas y signos, resultados analíticos, entidad nosológica, tipo de parto y complicación neonatal. Se elaboró una planilla para la recolección de los datos. Los resultados se analizaron en frecuencias absolutas y porcientos y se expusieron en tablas. Resultados: predominaron las gestantes del tercer trimestre con 61.6 %. El síntoma más frecuente fue el prurito en 33 gestantes (63.6%). La hipertransaminasemia se manifestó en el 100% de las gestantes. La entidad más frecuente fue la hepatitis crónica por virus B en 19 gestantes (36.5%) seguida de la colestasis intrahepática del embarazo con un 25 %. La mayoría de los partos fueron realizados por cesárea (94.2 %). La principal complicación neonatal fue el bajo peso al nacer en 26 (39.4 %). Conclusiones: las hepatopatías propias de la gestación se comportaron con igual frecuencia descrita en la literatura de acuerdo al trimestre que predominó, aunque fue significativa la incidencia de gestantes valoradas con infección por virus de la hepatitis b cuyo diagnóstico se hizo durante el embarazo siendo la principal causa de las complicaciones neonatales observadas (AU).


SUMMARY Introduction: Pregnancy supposes changes in the woman's physiology. These changes can lead to the appearance of illnesses affecting the liver, such as Hellp syndrome, intrahepatic cholestasis gravidarum, acute hepatic steatosis of pregnancy, among others, that can rebound in the course of the gestation. Materials and methods: a cross-sectional retrospective, descriptive, observational study was carried out in 52 pregnant women that were valued in Gastroenterology due to the suspicion of liver diseases during pregnancy in 2018; they were the universe of the study and the aim was determining the behavior of liver diseases during pregnancy in pregnant women valued in the service of Gastroenterology of the university hospital "Comandante Faustino Pérez Hernández" of the province of Matanzas: The studied variables were: gestational trimester, symptoms and signs, analytical results; nosological entity, type of delivery and neonatal complications. A form was draw up to collect data. The results were analyzed in absolute frequencies and percentages and showed in tables. Results: The third semester pregnant women predominated with 61.7 %. Pruritus was the most frequent symptom in 33 pregnant women (63.6 %). High levels of serum transaminases were present in 100 % of the studied women. The most frequent disease was chronic hepatitis caused by virus B in 19 pregnant women (36.5 %), followed by intrahepatic cholestasis of pregnancy with 25 %. Most of deliveries were performed by cesarean (94.2 %). The main neonatal complication was low weight at birth in 26 (39.4 %). Conclusions: liver diseases that are proper of gestation behaved in the same frequency as they are described in literature in relation to the predominating semester, although it was significant the incidence of assessed pregnant women with infection caused by the virus of hepatitis B diagnosed during pregnancy; it was the main cause of the observed neonatal complications (AU).

ABSTRACT

RESUMEN La pandemia declarada por la OMS originada por el COVID-19 (enfermedad infecciosa originada por el virus SARS-CoV2), desde su aparición en Wuhan, China en diciembre 2019; esta diseminándose rápidamente y de manera inesperada por todo el mundo originando millones de casos y miles de muertes, afectando más de 120 países y desde el 06 marzo 2020 al Perú, distribuyéndose rápidamente por todo el país, originando crisis y colapso del sistema de servicios de salud, especialmente de las atenciones en emergencia, hospitalizaciones y unidades de cuidados intensivos abarrotadas; sin tener aún un tratamiento específico ni la posibilidad de una vacuna a corto plazo. Se sabe actualmente que COVID-19, es una enfermedad sistémica que puede afectar múltiples órganos y tejidos y que puede ser fatal. El objetivo de esta revisión es mostrar lo descrito en los recientes estudios publicados a nivel mundial incluido nuestro país, que han reportado sus manifestaciones clínicas, esbozando posibles mecanismos de disfunción hepática relacionados a COVID-19 y sus repercusiones, en especial sobre el aparato digestivo; analizando y discutiendo el potencial impacto sobre ellas y las enfermedades del hígado, enunciando las recomendaciones de expertos y organizaciones científicas respecto a medidas de prevención, control y manejo, además de esbozar algunas estrategias de salud pública en nuestro país para la adecuada atención de estos pacientes en tiempos de crisis generalizada.


ABSTRACT The pandemic of COVID-19 (an infectious disease caused by the SARS-CoV2 virus), declared as such by the WHO, is spreading since its appearance in Wuhan (China) in December 2019, rapidly and unexpectedly throughout the world, causing millions of cases and thousands of deaths and has affected more than 120 countries. It was officially acknowledged in Peru on March 6th, 2020, and has spread rapidly throughout the country, causing first the crisis and then the collapse of the healthcare system, especially emergency care, admissions, and overcrowded intensive care units, not having a specific treatment or the foreseeable possibility of a short-term vaccine. COVID-19 is currently known for being a systemic disease that can affect multiple organs and tissues and can be fatal. The goal of this review is to present what has been described in recent studies, published worldwide and including our country, that have reported clinical manifestations, outlining possible mechanisms of liver dysfunction related to COVID-19 and its repercussions, especially on the digestive system. These studies analyze and discuss the potential impact on liver diseases, offering recommendations of experts and scientific organizations regarding prevention, control and management measures, outlining also some public health strategies in our country for the proper care of COVID-19 patients in times of widespread crisis.

ABSTRACT

Resumen Los granulomas son lesiones circunscritas compuestas principalmente por células mononucleares que surgen en respuesta a estímulos antigénicos pobremente degradables. Se encuentran en 2 a 15 % de las biopsias hepáticas; su hallazgo puede significar desde un fenómeno incidental, hasta la manifestación de una enfermedad sistémica de origen infeccioso, autoinmune o neoplásico. El cuadro clínico suele apuntar a la patología subyacente, sin embargo, la lista de condiciones asociadas es amplia y difiere con base en los antecedentes epidemiológicos y a las características basales del paciente. El elemento de mayor utilidad para su estudio es la historia clínica exhaustiva, con énfasis en viajes recientes, exposición de riesgo y consumo de fármacos o alimentos crudos o exóticos. El análisis histopatológico detallado puede auxiliar en la identificación de la etiología, por ejemplo, la presencia de granulomas epitelioides con necrosis caseosa indica tuberculosis y su ausencia, sarcoidosis; la abundancia de eosinófilos es señal de reacciones farmacológicas o infecciones parasitarias; la presencia de cuerpos extraños puede ser la causa de la enfermedad granulomatosa hepática. En este artículo describimos los aspectos clínico-patológicos básicos de esta enfermedad y proveemos un breve resumen de las etiologías más comunes, principalmente en la región de Latinoamérica.


Abstract Granulomas are circumscribed lesions mainly composed of mononuclear cells that arise in response to poorly degradable antigenic stimuli. They are found in 2-15 % of liver biopsies and the meaning of their finding can range from an incidental phenomenon to the manifestation of a systemic disease of infectious, autoimmune or neoplastic origin. Clinical presentation usually points at the underlying pathology; however, the list of associated conditions is extensive, and differs based on patient epidemiological history and baseline characteristics. The most useful element for their study is a thorough medical history, with an emphasis on recent trips, exposures and consumption of drugs or raw or exotic foods. Detailed histopathological analysis may help identify the etiology. For example, the presence of epithelioid granulomas with caseous necrosis indicates tuberculosis and, its absence, sarcoidosis; eosinophil abundance can be associated with drug reactions or parasitic infections; and the presence of foreign bodies can be the cause of granulomatous liver disease (GLD). In this article, we describe the basic clinical-pathological aspects of GLD, and provide a brief summary of the most common etiologies, with an emphasis on the Latin-American region.

ABSTRACT

Infantile systemic juvenile xanthogranuloma (ISJXG) is an uncommon form of juvenile xanthogranuloma, a non-Langerhans cell proliferation of infancy and early childhood. In a small percentage of patients, the visceral involvement­most commonly to the central nervous system, liver, spleen, or lungs­may be associated with severe morbidity, and eventually fatal outcome. Here we describe the clinical and pathological findings of a 28-day-old girl with ISJXG who died with respiratory distress syndrome. She had few cutaneous lesions but massive liver and spleen infiltration; other affected organs were multiple lymph nodes, thoracic parasympathetic nodule, pleura, pancreas, and kidneys. Additional findings were mild pulmonary hypoplasia and bacteremia. Immunohistochemistry on fixed tissues is the standard for diagnosis. Immunophenotype cells express CD14, CD68, CD163, Factor XIIIa, Stabilin-1, and fascin; S100 was positive in less than 20% of the cases; CD1a and langerin were negative. No consistent cytogenetic or molecular genetic defect has been identified. This case demonstrates that the autopsy is a handy tool, because hepatic infiltration, which was not considered clinically, determined a restrictive respiratory impairment. In our opinion, this was the direct cause of death.

ABSTRACT

RESUMEN La rotura hepática es una complicación poco frecuente de la gestación que se asocia a preeclampsia y síndrome HELLP, aumentando la morbimortalidad materna. No hay reportados casos de esta patología en gestantes residentes en altura, a pesar de que se considera a la altura como un factor que influye en la gestación. En este artículo se reporta el caso de una gestante residente de la gran altura, la cual evidenció una rotura hepática con sangrado persistente, siendo reintervenida por cirugía de emergencia oportunamente gracias al monitoreo hemodinámico con doppler transesofágico.


ABSTRACT Hepatic rupture is a rare complication of pregnancy associated with preeclampsia and HELLP syndrome, thus increasing maternal morbidity and mortality. There are no reported cases of this condition in high-altitude dweller pregnant women, even though altitude is considered a factor that influences in pregnancy. In this article the case of a pregnant dweller at high altitude is reported, which revealed hepatic rupture with persistent bleeding, being reoperated by Emergency Surgery appropriately thanks to the hemodynamic monitoring with transesophageal Doppler

ABSTRACT

Las fosfatasas alcalinas (FA) son un grupo de 4 isoenzimas que se producen en diversos tejidos, pudiendo elevarse en condiciones fisiológicas y secundariamente a enfermedades óseas o hepatobiliares. En niños una de las causas más frecuentes e inocuas, pero poco conocidas, es la hiperfosfatasemia transitoria benigna de la infancia (HFTBI). El objetivo es reportar una serie de casos de HFTBI y proponer un criterio de enfrentamiento. Casos clínicos: Se presentan 5 niños de entre 11 y 50 meses de edad, 4 de ellos de sexo femenino, con hallazgo incidental de elevación severa (> 1.000 UI/l) en los niveles de FA en exámenes solicitados por mal incremento pondo-estatural o por cuadros infecciosos. A través de la anamnesis, examen físico y laboratorio básico se descartó enfermedad ósea o hepática. En 2 de los pacientes se determinaron las isoenzimas, destacando el predominio óseo. Se comprobó una normalización de los niveles de FA en un periodo de uno a 6 meses, sin evidencia de complicaciones posteriores. Conclusión: La HFTBI es un desorden bioquímico benigno de evolución autolimitada, que es importante tener presente al enfrentar un niño menor de 5 años con elevación severa de FA, en ausencia de alteraciones clínicas o de laboratorio que sugieran enfermedad ósea o hepática.


Alkaline Phosphatase (ALP) is a group of 4 isoenzymes produced in different tissues. Elevated levels of ALP can be developed under physiological conditions, and can indicate the presence of bone or hepatobiliary diseases. In children, one of its most common harmless causes is benign transient hyperphosphatasaemia (BTH), a little known condition. The objective is to report BTH cases and propose a monitoring plan. Case reports: The cases of 5 children aged between 11 and 50 months are presented, 4 of them female, with the incidental finding of a sudden and severe ALP elevation (> 1,000 U/l), in tests ordered due to either abnormal growth and development, or intercurrent infections. Bone and liver disease were ruled out using the patient history, physical examination and basic laboratory results. Isoenzymes levels were determined in 2 patients. A return to normal ALP levels was observed over a period of 1-6 months, with no evidence of further complications. Conclusion: BTH is a benign self-limiting biochemical disorder, which should be considered in children under 5 years old with severe ALP elevation in the absence of clinical or laboratory abnormalities suggestive of bone or liver disease.

ABSTRACT

We report an asymptomatic 23-year-old woman with an isolated and persistent increase in serum levels of aspartate aminotransferase (AST). An extensive work up including laboratory and image testing revealed no abnormalities thus suggesting the presence of macro-AST. A polyethylene glycol (PEG) precipitation assay was performed and confirmed the presence of macro-AST.

ABSTRACT

Este estudo avaliou a capacidade de um sal mineral rico em molibdênio (Mo) em prevenir a intoxicação cúprica acumulativa (ICA), mediante a análise das variáveis clínicas e dos teores de cobre (Cu) e Mo hepático. Foram utilizados 25 ovinos cruzados da raça Ile-de-France, aleatoriamente distribuídos igualmente em cinco grupos, em que o grupo 1 recebia dieta contendo 80% de volumoso e 20% de concentrado, os grupos 2 e 3 recebiam 50% de volumoso e 50% de concentrado, e os grupos 4 e 5 recebiam a mesma dieta dos grupos 2 e 3, com a adição diária de 150mg de sulfato de Cu. Os grupos 1, 3 e 5 recebiam sal mineral contendo 300ppm de Mo. Foram realizadas três biópsias hepáticas para determinação de Cu, Mo e Zn. Três ovinos do grupo 4 e um do grupo 5 manifestaram ICA. Não houve diferença na frequência de mortalidade entre os grupos (P=0,56). Os teores de Cu hepático nos ovinos com ICA (2450ppm) foram superiores aos que não intoxicaram (1518ppm). Quanto maior a ingestão de Mo na dieta, menor foi o acúmulo de Cu hepático ao término do experimento (r = -0,72).(AU)


The aim of this project is to evaluate the capacity of a molybdenum-rich mineral salt in the prevention of cumulative cooper poisoning (CCP) in sheep, through clinical and hepatic copper and molybdenum concentrations. Twenty five crossbreed Ile-de-France sheep were randomly distributed equally into five groups. Group 1 received a 80% forage and 20% concentrate diet, groups 2 and 3 received a 50% forage and 50% concentrate diet, and groups 4 and 5 received the same diet as groups 2 and 3 with a daily supplementation of 150 mg of copper sulfate. Groups 1, 3 and 5 received a mineral salt with 300 ppm of molybdenum. Three times during the experiment a liver biopsy was carried out to evaluate the degree of copper accumulation. Three sheep from group 4 and one sheep from group 5 showed a clinical picture of CCP. There was no difference in the frequency of mortality between groups 4 and 5 (P=0.56). The liver copper concentration was higher in sheep with CCP (2450 ppm) compared to sheep that did not present CCP (1518 ppm). The higher the ingestion of molybdenum in the diet the lower the liver copper concentration at the end of the experiment (r=-0.72).(AU)

ABSTRACT

A gestação é um período de significativas modificações no organismo materno, que objetivam promover a homeostase do binômio materno-fetal. Sob o ponto de vista hepático, demais das alterações conspícuas à gravidez, deve o obstetra detectar precocemente anomalias envolvendo o fígado, que complicam até 3% das gestações e são responsáveis por elevada mortalidade materna e perinatal. Por outro lado, certas doenças hepáticas têm sua história natural modificada quando ocorrem durante a gestação, demandando cuidados especiais de uma equipe multidisciplinar que envolva o obstetra e o hepatologista. Este artigo revisa as modificações fisiológicas do sistema hepático na gravidez, assim como suas alterações hepáticas mais prevalentes no Brasil. O objetivo é auxiliar e fornecer orientações ao obstetra e guiar o melhor cuidado das pacientes a fim de prevenir e reduzir as complicações hepáticas na gravidez.(AU)


Pregnancy is a period of significant changes in the mother's organism aimed at promoting the mother-fetus homeostasis. From the hepatic standpoint, the obstetrician should detect early the abnormalities attacking the liver, which complicates up to 3% of pregnancies and are responsible for high rates of maternal and perinatal mortality. On the other hand, some liver diseases have their natural evolution changed when they occur during the pregnancy, requiring special care of a multidisciplinary team involving obstetrician and hepatologist specialists. This study presents the physiological changes of the hepatic system during pregnancy, as well as the most prevalent pregnancy hepatic disorders occurring in Brazil. It aims to help the obstetrician and guide the best patient care to prevent and reduce hepatic complications in pregnancy.(AU)
