RESUMO

La hipertensión portal es una de las principales complicaciones de la cirrosis. El papel de la derivación portosistémica transyugular intrahepática (TIPS, por sus siglas en inglés), ha ganado aceptación como tratamiento efectivo en la hipertensión portal. En los últimos años su técnica se ha ido perfeccionando, disminuyendo la morbimortalidad relacionada con este procedimiento. Describimos un caso de un paciente masculino con cirrosis Child-Pugh 8 y MELD 16, con antecedente de descompensación por sangrado variceal recurrente y trombosis parcial de la vena porta, con un gradiente de presión venosa hepática (GPVH) de 20 mmHg, por lo que es llevado a TIPS como profilaxis secundaria, con un gradiente final post-TIPS de 6 mmHg. Posterior al procedimiento, presentó evolución tórpida con deterioro de las pruebas de bioquímica hepática. Se realizó una angiografía demostrando permeabilidad del TIPS sin progresión de la trombosis portal, y hallazgos anormales inespecíficos de la arteria hepática. Se decidió realizar una arteriografía selectiva, demostrando un pseudoaneurisma de la rama derecha de la arteria hepática y una fístula arteriovenosa de la arteria hepática a las colaterales portales. Se realizó embolización selectiva de la fístula con evolución satisfactoria del paciente.


Portal hypertension is a life-threatening complication of cirrhosis. The role of transyugular intrahepatic portosystemic shunt (TIPS) has gained acceptance as an effective treatment for portal hypertension. In the past few years, its technique has been improved, decreasing the mortality related with the procedure. We describe a case of a male with Child-Pugh 8 and MELD 16 cirrhosis, with previous decompensation of recurrent variceal bleeding and partial thrombosis of the portal vein. TIPS was performed due to a hepatic venous pressure gradient (HVPG) of 20 mmHg. The final measure showed HVPG of 6 mmHg. After the procedure, he presented a torpid evolution with deterioration of liver function tests. An angiography was performed demonstrating patency of the TIPS without progression of portal thrombosis and nonspecific abnormal findings of the hepatic artery. Selective arteriography was performed and revealed a pseudoaneurysm of the right branch of the hepatic artery and an arteriovenous fistula (AVF) from the hepatic artery to portal collaterals. Embolization was performed to treat the fistula with satisfactory evolution of the patient.

RESUMO

Contexto: el síndrome hepatorrenal es una disfunción renal que ocurre en pacientes con enfermedad hepática crónica como cirrosis hepática o enfermedad hepática aguda, caracterizada por la activación de mecanismos reguladores que conducen a la disminución de la tasa de filtrado glomerular. Clínicamente, el síndrome hepatorrenal se divide en dos tipos: el tipo 1 se caracteriza por una pérdida rápida y progresiva de la función renal, mientras que el tipo 2 se caracteriza por ser de progresión lenta y de mejor pronóstico. Objetivo: analizar la historia natural de la enfermedad que presentan los pacientes que desarrollan síndrome hepatorrenal. Metodología: se realizó una revisión de la literatura científica de manuscritos publicados sobre síndrome hepatorrenal, para evaluar la historia natural de esta patología. Resultados: no existen hallazgos clínicos específicos, sin embargo, sus manifestaciones clínicas reflejan la enfermedad hepática avanzada subyacente, la insuficiencia renal y las anomalías circulatorias presentes. Conclusiones: la opción terapéutica más adecuada es el trasplante hepático, pero no todos los pacientes pueden recibirlo, mientras se accede a dicho manejo una opción es el tratamiento medicamentoso con vasoconstrictores y albúmina.


Background: Hepatorenal syndrome is a renal dysfunction that occurs in patients with chronic liver disease such as liver cirrhosis or acute liver disease, characterized by the activation of regulatory mechanisms that lead to a decrease in the glomerular filtration rate. Clinically, hepatorenal syndrome is divided into two types, type 1 and type 2. Type 1 is characterized by a rapid and progressive loss of kidney function while type 2 is characterized by slow progression and a better prognosis. Purpose: To analyze the natural history of the disease presented by patients who develop hepatorenal syndrome. Methodology: A review of the scientific literature of published manuscripts on hepatorenal syndrome was carried out to evaluate the natural history of this pathology. Results: There are no specific clinical findings, however, its clinical manifestations reflect the underlying advanced liver disease, kidney failure, and circulatory abnormalities present. Conclusions: The most appropriate therapeutic option is liver transplantation, but not all patients can receive it, while accessing said management an option is drug treatment with vasoconstrictors and albumin.

RESUMO

FadD is an acyl-coenzyme A (CoA) synthetase specific for long-chain fatty acids (LCFA). Strains mutated in fadD cannot produce acyl-CoA and thus cannot grow on exogenous LCFA as the sole carbon source. Mutants in the fadD (smc02162) of Sinorhizobium meliloti are unable to grow on oleate as the sole carbon source and present an increased surface motility and accumulation of free fatty acids at the entry of the stationary phase of growth. In this study, we found that constitutive expression of the closest FadD homologues of S. meliloti, encoded by sma0150 and smb20650, could not revert any of the mutant phenotypes. In contrast, the expression of Escherichia coli fadD could restore the same functions as S. meliloti fadD. Previously, we demonstrated that FadD is required for the degradation of endogenous fatty acids released from membrane lipids. Here, we show that absence of a functional fadD provokes a significant loss of viability in cultures of E. coli and of S. meliloti in the stationary phase, demonstrating a crucial role of fatty acid degradation in survival capacity.

RESUMO

The intracellular deposition of amyloid-ß (Aß) peptides has been described in the brains of both Alzheimer's disease (AD) patients and animal models. A correlation between the intracellular amyloid burden and neurodegeneration has recently been reported in a triple-transgenic AD (3xTg-AD) murine model. In the present study, we assessed the effect of scFv-h3D6, an anti-Aß single-chain variable fragment (scFv) derived from the antibody bapineuzumab, on amyloid pathology in 5-month-old 3xTg-AD female mice, focusing on intracellular Aß clearance, neuronal survival, and functional abilities. We also examined neuroinflammation and the histology of peripheral organ samples to detect any adverse effects. A single intraperitoneal injection of scFv-h3D6 dramatically reduced intracellular Aß burden in the deep layers of the cerebral cortex, pyramidal cells layer of the hippocampus, and basolateral amygdalar nucleus. The treatment prevented neuronal loss in the hippocampus and amygdala, while neither astrogliosis nor microgliosis was induced. Instead, an increase in the size of the white pulp after the treatment indicated that the spleen could be involved in the clearance mechanism. Although the treatment did not ameliorate behavioral and psychological symptoms of dementia-like symptoms, the results of cognitive testing pointed to a noticeable improvement in spatial memory. These findings indicated that the mechanism underlying the therapeutic effect of scFv-h3D6 was the clearance of intracellular Aß, with subsequent prevention of neuronal loss and amelioration of cognitive disabilities. The treatment was safe in terms of neuroinflammation and kidney and liver function, whereas some effects on the spleen were observed.

RESUMO

Las metástasis sintomáticas al colon de un carcinoma de pulmón son raras, a pesar de ser una neoplasia que representa el 12,9% de la incidencia mundial de cáncer. El colon es un sitio infrecuente de metástasis, con una prevalencia reportada menor al 0,5% en pacientes con carcinomas de pulmón, existiendo en la literatura mundial pocos casos. Es inusual que sea la forma de presentación de este tipo de neoplasia. Con respecto a las manifestaciones clínicas que se reportan pueden cursar con obstrucción intestinal como síntoma cardinal. Se presenta el caso de un paciente que curso con hemorragia de vías digestivas bajas como manifestación inicial de múltiples lesiones metastásicas a colon de un carcinoma de pulmón de célula no pequeña.

RESUMO

Fibrolamellar hepatocarcinoma is an infrequent liver tumor, currently considered to be a variant different from hepatocarcinoma. The differences lie in genomic alterations, a greater prevalence of fibrolamellar hepatocarcinoma in young patients, and its lack of association with underlying liver disease. The clinical presentation is unspecific, with symptoms ranging from abdominal pain, malaise, and weight loss to atypical manifestation which include hyperammonemic encephalopathy. We present the case of a 33-year-old woman with no prior medical history who presented with a coma and a diagnosis of inoperable fibrolamellar hepatocarcinoma requiring a cadaver donor transplant. While she was on the waiting list, she received hemofiltration and ammonium benzoate treatment, with progressive improvement in her state of consciousness.

RESUMO

Resumen Introducción: cerca del 10% al 15% de los pacientes con coledocolitiasis presentan cálculos gigantes, definidos como aquellos que miden más de 10 mm a 15 mm. La extracción de estos puede ser problemática, aun para endoscopistas experimentados. Casi todos los pacientes con esta patología pueden ser tratados endoscópicamente, y la mayoría de los cálculos son removidos con la realización de esfinterotomía (EFT), litotripsia mecánica (LM) o dilatación papilar con balón grande (DPBG). La DPBG ha demostrado ser efectiva en el manejo del cálculo gigante y disminuye la necesidad de LM. Objetivos: determinar la prevalencia de coledocolitiasis gigante en el Hospital Universitario de la Samaritana (HUS) entre el 2009 y el 2014, la frecuencia de éxito endoscópico y la necesidad de manejo quirúrgico, además de evaluar los factores asociados con el uso de litotripsia en casos de cálculos gigantes de la vía biliar. Materiales y métodos: el presente es un estudio de casos y controles de pacientes con cálculos gigantes, definidos como cálculos mayores de 10 mm en pacientes llevados a colangiopancreatografía retrógrada endoscópica (CPRE) en el HUS entre 2009 y 2014. Los casos fueron los pacientes a quienes se les realizó litotripsia y, los controles, quienes no requirieron este procedimiento. Los resultados se presentan como medias o medianas, y se indican sus respectivas medidas de dispersión para las variables continuas, según pruebas de normalidad o como frecuencias y porcentajes para las variables categóricas. Se realizó un análisis de regresión logística con el principal objetivo de determinar los factores asociados con litotripsia, en el que se incluyeron las variables biológicamente plausibles o que, estadísticamente, mostraron diferencias en el análisis bivariado (p<0,200). Los resultados se presentan como odds ratios (oportunidad relativa) ajustados (ORA). Resultados: entre 2009 y 2014, se realizaron un total de 1403 CPRE, de las cuales 198 (14,1%) tuvieron presencia de cálculos gigantes. Fue más frecuente la coledocolitiasis gigante en el sexo femenino que en el masculino. La edad promedio de los pacientes fue de 66,6 años. El diámetro promedio del colédoco fue de 18 mm, y el diámetro promedio de los cálculos fue de 18 mm. Al 99% de los pacientes se les realizo EFT, el 28% requirió LM, al 48% se les realizo DPBG, el 5,5% requirió LM y DPBG, y el 30,8% requirió el avance de prótesis biliar y más de una CPRE para la resolución de la coledocolitiasis. En el 89,9% de los casos, el manejo endoscópico fue exitoso. El 10,1% requirió cirugía. En el 9,0% de los casos, se presentaron complicaciones (6 pancreatitis, 7 sangrados, 2 impactaciones de canastilla y 1 perforación). En el análisis bivariado, la DPBG fue un factor protector del requerimiento de LM (ORA 0,07-IC del 95% 0,025-0,194), y el tamaño del colédoco es un predictor del requerimiento de LM (p<0,05). Conclusiones: en nuestra serie, la prevalencia de coledocolitiasis gigante y el éxito del manejo endoscópico es similar a la reportada en la literatura. La EFT, la LM y la DPBG fueron efectivas en el manejo de los cálculos gigantes. El tamaño del colédoco es un predictor de requerimiento de LM y la DPBG disminuyó el requerimiento de LM.


Abstract Introduction: About 10% to 15% of patients with choledocholithiasis develop a giant calculus, defined as one that measures more than 10 mm to 15 mm. Removal of these stones can be problematic even for experienced endoscopists. Almost all patients with this pathology can be treated endoscopically: most are removed with sphincterotomies, mechanical lithotripsy (ML) or large balloon papillary dilatation (LBPD). LBPD has been shown to be effective in handling giant calculi and decreases the need for ML. Objectives: The aim of this study was to determine the prevalence of giant choledocholithiasis at HUS between 2009 and 2014, the frequency of successful endoscopic treatment, and the frequency of surgery in these cases. We also evaluated factors associated with the use of lithotripsy to remove giant biliary calculi. Materials and Methods: This study is a case-control study of patients who had giant calculi and underwent ERCP at the HUS between 2009 and 2014. Calculi larger than 10 mm were defined as giant. Cases were patients who underwent lithotripsy while controls were those who did not require lithotripsy. The results for continuous variables are presented as means or medians and their respective measures of dispersion while results for categorical variables are presented according to tests of normality or as frequencies and percentages. A logistic regression analysis was used to determine factors associated with lithotripsy. Biologically plausible variables and those that had statistically significant differences in the bivariate analysis (p <0.200) were included. The results are presented as adjusted odds ratios (ORA). Results: Between 2009 and 2014, a total of 1403 ERCPs were performed. Giant calculi were found in 198 (14.1%) of these procedures. Giant choledocholithiasis was more common in female patients than in male patients. The patients' mean age was 66.6 years. The average diameter of the common bile duct was 18 mm, and the average diameter of the stones was 18 mm. Ninety-nine percent of these patients underwent sphincterotomies, 28% required ML, 48% underwent LBPD, 5.5% required ML and LBPD, and 30.8% required biliary stents and more than one ERCP for the resolution of choledocholithiasis. In 89.9% of cases, endoscopic management was successful. Only 10.1% of the total number of patients required surgery. Complications occurred in 9.0% of the cases: 6 cases of pancreatitis, 7 cases of bleeding, 2 impacted cannula and 1 perforation. In the bivariate analysis, LBPD was a protective factor against the need for ML (ORA 0.07-IC 95% 0.025-0.194) and choledochal size was a predictor a need for MM (p <0.05). Conclusions: In our series the prevalence of giant choledocholithiasis and the success of endoscopic management are similar to those reported in the literature. Sphincterotomies, ML and LBPD were effective for managing giant calculi. Choledochal size is a predictor of a need for ML while performance of LBPD decreased the need for ML.

RESUMO

Antecedentes: el 90% de los pacientes cirróticos desarrollará várices esofágicas, y en algún momento de su vida, el 30% de ellos sangrará. Objetivo: identificar los factores pronósticos asociados con mortalidad en cirróticos con sangrado digestivo varicoso. Método: se presenta una cohorte retrospectiva de pacientes con sangrado digestivo varicoso en un período de 30 meses. Resultados: se presentan 63 pacientes (33 hombres y 30 mujeres), de 56 años (desviación estándar DE 16 años) de edad media. El 52,4% tenía una clase funcional Child-Pugh B. El promedio de hospitalización fue de 10 días. De estas, 12 (19%) fallecieron; el choque hipovolémico (p = 0,033) y la transfusión de glóbulo rojos (p = 0,05) estuvieron relacionados con la mortalidad. En el análisis bivariado, la variable más relacionada con la mortalidad fue el compromiso funcional hepático Child-Pugh C (p = 0,00). Las comparaciones de las variables numéricas encontraron que el valor de creatinina; media 1,74 mg/dL (p = 0,043); y la duración de la hospitalización; media de 10 días (p = 0,057); fueron superiores en los pacientes fallecidos. En los análisis bivariados, las variables Child-Pugh C (Exp(B) = 0,068; p = 0,002) y creatinina (Exp(B) = 0,094; p = 0,034) se mantuvieron estadísticamente relacionadas con el desenlace de interés. Conclusiones: la mortalidad del paciente con sangrado varicoso en este estudio es comparable con los estándares internacionales actuales. La enfermedad hepática avanzada y una función renal deteriorada están relacionadas con mayor mortalidad, razón por la cual los pacientes con predictores de mortalidad presentes durante la descompensación por sangrado varicoso ameritan una vigilancia estrecha e intervenciones tempranas para evitar desenlaces negativos


Background: Ninety percent of cirrhotic patients will develop esophageal varices, and bleeding will occur in 30% of these patients at some point in their lives. Objective: The objective of this study was to identify prognostic factors associated with mortality in cirrhotic patients with bleeding varices. Method: We present a retrospective cohort study of patients with bleeding digestive varices over a period of 30 months. Results: This study included 63 patients (33 men and 30 women) whose average age was 56 years (SD: 16 years). 52.4% of these patients’ Child-Pugh classification was B. The average stay in the hospital was 10 days. Twelve (19%) died. Hypovolemic shock (p = 0.033) and red blood cell transfusion (p = 0.05) were related to mortality. Bivariate analysis showed that the variable most closely related to mortality was hepatic impairment with Child-Pugh C classification (p = 0.00). Comparisons of numerical variables found that the creatinine value (Mean: 1.74 mg/dl, p = 0.043) and length of hospital stay (mean time:10 days, p = 0.057) were higher in patients who died. In the bivariate analysis, Child-Pugh C (Exp (B) = 0.068, p = 0.002) and creatinine (Exp (B) = 0.094, p = 0.034) remained statistically related to the outcome of interest. Conclusions: Mortality from bleeding varices in the patients in this study is comparable to current international standards. Because advanced liver disease and impaired renal function are associated with increased mortality, patients with bleeding varices who have predictors for mortality during decompensation due to bleeding warrant close monitoring and early interventions to avoid negative outcomes

RESUMO

Se reporta el caso de una mujer anciana con hemorragia digestiva alta y choque hipovolémico secundario a úlceras de Cameron. Dado que estas lesiones se caracterizan por presentar cuadros crónicos de hemorragia sin aparente repercusión, se hace una revisión de esta exótica causa de sangrado digestivo masivo con repercusión hemodinámica. Estas ulceras se deben a abrasión de la mucosa por la contracción del diafragma durante los movimientos respiratorios, lo que genera pérdidas crónicas de sangre.


A case of an elderly woman with upper gastrointestinal bleeding and hypovolemic shock, secondary to Cameron ulcers, is presented. Since these injuries are characterized by showing chronic hemorrhage medical profiles chronic with no apparent impact a review of this exotic cause of massive gastrointestinal bleeding with hemodynamic impact is performed. These mucosal ulcers are formed due to abrasion during the contraction of the diaphragm in the breathing movements, which in turn produces chronic blood loss.

Objective: To provide a clinical practice guideline with the latest evidence for diagnosis and treatment of nonalcoholic fatty liver disease for patients, caregivers, administrative and government bodies at all levels of care in Colombia. Materials and Methods: This guide was developed by a multidisciplinary team with the support of the Colombian Association of Gastroenterology, Cochrane STI Group and Clinical Research Institute of the Universidad Nacional de Colombia. Relevant clinical questions were developed and the search for national and international guidelines in databases was performed. Existing guidelines were evaluated about quality and applicability. One guideline met the criteria for adaptation, so the group decided to adapt 3 clinical questions. Systematic literature searches were conducted by the Cochrane Group. The tables of evidence and recommendations were made based on the GRADE methodology. The recommendations of the guide were socialized in a meeting of experts with government agencies and patients. Results: An evidence-based Clinical Practice Guidelines for the diagnosis and treatment of nonalcoholic fatty liver disease was developed for the Colombian context. Conclusions: The opportune detection and appropriate management of nonalcoholic fatty liver disease would contribute to the burden of the disease in Colombia.

RESUMO

Introducción: la infección por el virus de la hepatitis C (HCV sus siglas en inglés) es un problema de salud pública en el mundo y la Organización Mundial de la Salud (OMS) calcula en más de 180 millones las personas infectadas. El objetivo del presente estudio es determinar la prevalencia de anti-HCV en pacientes con alto riesgo de infección mediante una prueba rápida con sangre capilar, y la confirmación de la infección por la prueba de PCR en tiempo real. Método: se incluyeron pacientes atendidos en la Unidad de gastroenterología del Hospital Universitario de La Samaritana de Bogotá D.C, principal centro de referencia del departamento de Cundinamarca y que atiende pacientes de todo el país. Se definieron como factores de riesgo para hepatitis C: antecedentes de transfusiones, hemodiálisis, cirugías mayores (sistema nervioso central [SNC], tórax, abdomen, ortopédicas), drogadicción (farmacodependencia), tatuajes, piercing, acupuntura, presidiarios, trabajadores sexuales, VIH/sida, enfermedades de trasmisión sexual, trabajadores de la salud, pacientes procedentes de la Orinoquía y/o Amazonía, e insuficiencia renal crónica; también se estudiaron pacientes remitidos por alteración del perfil hepático, hígado graso, masas hepáticas, cirrosis excepto por virus C, ascitis, y várices esofagogástricas. Se empleó el estuche comercial SD BIOLINE HCV (Standard Diagnostics, INC. Corea), esta prueba contiene una membrana precubierta con antígenos recombinantes del HCV (core, NS3, NS4, NS5); se combina una proteína A coloidal con la muestra de suero y se mueve a lo largo de la membrana cromatográfica formando una línea visible de reacción antígeno-anticuerpo-proteína A, con un alto grado de especificidad y sensibilidad. Resultados: entre enero y octubre de 2014 se estudiaron 391 pacientes, 161 mujeres (41%) y 230 (59%) hombres; edad promedio de 46,6 años y rango de edad de 14 a 86 años. Se detectaron, por la prueba rápida para hepatitis C, ...


Introduction: Hepatitis C virus (HCV) infections are a public health problem throughout the world: the World Health Organization (WHO) estimates that over 180 million people are currently infected. The aim of this study is to determine the prevalence of anti-HCV in patients at high risk of infection through using a rapid test with capillary blood and confirmation of infection by PCR testing in real time. Method: Patients were enrolled in the study from among those treated in the gastroenterology unit of the Hospital Universitario de La Samaritana. This is one of the principal referral centers in the department of Cundinamarca, but it cares for patients from across the country. Hepatitis C risk factors identified included previous history of hepatitis C, transfusions, hemodialysis, major surgery (SNC, thorax, abdomen, orthopedic), drug addiction, tattooing, piercing, acupuncture, time in prison, experience as a sex worker, HIV/AIDS, sexually transmitted diseases, health care work, chronic renal failure, and time spent living in the chronic renal failure the Orinoco and/or Amazon regions. Patients referred because of abnormal liver profiles, fatty liver disease, liver masses, cirrhosis (except when due to Hepatitis C virus), ascites, and esophageal-gastric varices were also included in the study. The SD BIOLINE HCV One Step Hepatitis C Virus Test (Standard Diagnostics, Inc. Korea), which is a commercially available kit, was used. This test contains a membrane which is pre-coated with recombinant HCV antigens (core, NS3, NS4, and NS5). A Protein A colloid is combined with the serum sample which then moves along the chromatographic membrane forming a visible line showing the antigen-antibody- Protein A reaction. This test has a high degree of specificity and sensitivity. Results: Between January and October 2014, 391 patients were included in the study. Of this number, 161 were women (41%) and 230 were men (59%). Average patient age was 46.6 ...

RESUMO

A 38 years old man with 48 hours of gastrointestinal bleeding was admitted to the hospital. The EGD revealed red-purple nodules in the gastric antrum. Histopathologically, there were spindle cells and capillary size vascular proliferation. These findings were consistent with Kaposi sarcoma of the stomach. Immediately after, the patient had a positive test for HIV.

RESUMO

The coexistence of pregnancy and liver disease represents a complex clinical situation. Pregnancy develops hypervolemic state due to increased splachnic blood flow, which contributes to increased portal pressure transmitted to collateral veins that increase the risk of variceal bleeding in these patients. We report the case of a 39 years old patient in the sixth pregnancy and without any previous medical history that presented pre-sinusoidal portal hypertension, and thanks to appropriate multidisciplinary management had an uncomplicated delivery. We review the literature relevant to the case.

RESUMO

Hombre de 38 años que consultó por sangrado digestivo de dos días de duración. La esofagogastroduodenoscopía demostró múltiples lesiones nodulares de color púrpura en el antro gástrico. La histopatología mostró un tumor formado por células fusiformes y proliferación vascular, hallazgos consistentes con sarcoma de Kaposi del estómago. Posteriormente se determinó la infección por virus de inmunodeficiencia (VIH) del paciente.
