Daño hepático inducido por uso de anticonceptivos orales en una paciente con ictericia prolongada y transaminasas elevadas: reporte de caso / Drug-induced liver injury secondary to the use of oral contraceptives in a patient with prolonged jaundice and elevated transaminases: Case report

La hepatotoxicidad inducida por medicamentos es un diagnóstico de descarte. Típicamente, se presenta en pacientes que desarrollan cambios clínicos y bioquímicos compatibles con hepatitis, pero relacionados con el inicio reciente de agentes farmacológicos, y que se resuelven tras el retiro de la noxa. Su desarrollo se ha descrito con el uso de algunos antibióticos, antituberculosos, estatinas, herbolarios y antiinflamatorios no esteroideos; sin embargo, hay pocos reportes de casos con el uso de anticonceptivos orales, en los cuales el surgimiento de mecanismos idiosincráticos puede llevar a la presentación de características clínicas como ictericia y anormalidades en los exámenes de laboratorio, como la elevación de las transaminasas. Esto requiere de estudios extensos para descartar otras patologías que pueden presentarse de esta forma, lo que representa un reto clínico. En este artículo se muestra el reporte de un caso de una paciente con antecedente de uso crónico de anticonceptivos implantables y que, tras el ajuste de la terapia con el inicio de anticonceptivos orales, desarrolla un episodio de elevación marcada de transaminasas e ictericia.

Drug-induced liver injury is a rule-out diagnosis. Typically, it occurs in patients who develop clinical and biochemical changes compatible with hepatitis, but related to a history of recent onset of pharmacological agents, and resolves after withdrawal of the noxious substances. Its development has been described with the use of some antibiotics, antituberculosis agents, statins, herbal and nonsteroidal anti inflammatory drugs; however, there are few reports of cases with the use of oral contraceptives, in which the appearance of idiosyncratic mechanisms can lead to the presentation of clinical features such as jaundice and laboratory tests abnormalities, like transaminase elevation, requiring extensive studies to rule out other pathologies that may have this clinical presentation, wich represents a clinical challenge. We present a case report of a patient who had chronic use of implantable contraceptives and who, after adjustment of therapy with the start of oral contraceptives, developed an episode of marked elevation of transaminases and jaundice.

Absceso hepático en Cali, Colombia / Liver abscess in Cali, Colombia

INTRODUCCIÓN: El absceso hepático (AH) es el tipo mas común de abscesos viscerales. Se estima que el perfil epidemiológico de esta enfermedad ha cambiado con el aumento de la resistencia de los microorganismos y el uso de nuevos medicamentos. OBJETIVO: Describir las características demográficas y clínicas de los pacientes hospitalizados con diagnóstico de AH en un hospital universitario del suroccidente colombiano. MÉTODOS: Se realizó un estudio observacional retrospectivo, en la Fundación Valle del Lili, Cali, Colombia. Se incluyeron pacientes mayores de 18 años con diagnóstico de AH hospitalizados entre 2011-2020. RESULTADOS: Se incluyeron 182 pacientes. La mediana de edad fUe 56 años (rango intercuartílico, 45-67) y 62,1% fueron hombres. El microrganismo mas común fue Klebsiella pneumoniae (17,6%). La mayoría requirió drenaje percutáneo (58,2%). El 58,8% tuvo un absceso único y 54,4% fue manejado en cuidados intensivos. El 7,1% de los pacientes falleció. Al comparar los casos que fueron manejados en cuidados intensivos vs. aquellos que no lo fueron, hubo más hepatomegalia (28,3 vs. 11,0%, p = 0,004), derrame pleural derecho (48,5 vs. 28,1%, p = 0,010), cirugía (42,4 vs. 13,4%, p < 0,001), falla terapéutica (22,2 vs. 7,3%, p = 0,007) y muerte (12,1 vs. 1,2%, p = 0,005) en los atendidos en UCI. CONCLUSIÓN: Las Enterobacterales son la principal causa de AH en nuestra población. La mortalidad ha disminuido, pero la hospitalización en cuidados intensivos sigue siendo alta.

BACKGROUND: Liver abscess (LA) is the most common type of visceral abscess. It is estimated that the epidemiological profile of this disease has changed with the increase in resistance and the use of new drugs. AIM: To describe the demographic and clinical characteristics of hospitalized patients with a diagnosis of LA in a university hospital in the southwestern region of Colombia. METHODS: A. retrospective observational study was conducted at Fundación Valle del Lili, Cali, Colombia. Patients older than 18 years with a diagnosis of LA hospitalized between 2011-2020 were included. RESULTS: A total of 182 patients were included. The median age was 56 years (interquartile range, 45-67) and 62.1% were men. The most common microorganism was Klebsiella pneumoniae (17.6%). The majority required percutaneous drainage (58.2%). A 58.8% had a single abscess and 54.4% were treated in ICU. A 7.1% of the patients died. When comparing cases treated in the ICU vs. those who did not, there was more hepatomegaly (28.3 vs. 11.0%, p = 0.004), right pleural effusion (48.5 vs. 28.1%, p = 0.010), surgery (42.4 vs. 13.4%, p < 0.001), therapeutic failure (22.2 vs. 7.3%, p = 0.007) and death (12.1 vs. 1.2%, p = 0.005) in patients treated in ICU. CONCLUSION: Enterobacterales are the main cause of LA in our population. Mortality has decreased, but intensive care hospitalization remains high.

Diagnóstico y tratamiento de abscesos hepáticos, a propósito de tres casos

El absceso hepático tiene baja incidencia, pero alta mortalidad. Su diagnóstico suele ser tardío dada la variabilidad de presentaciones clínicas. Presentamos tres casos en mujeres, de los cuales dos se manifestaron con síndrome febril con microbiología no precisada, mientras que el tercero con shock séptico secundario a colangitis, aislándose Escherichia coli. Todos fueron manejados con antibioticoterapia endovenosa empírica y drenaje quirúrgico, uno vía laparoscópica, dos percutáneos y uno asociado a una colangio-pancreatografía retrógrada endoscópica. La elección terapéutica se determina de acuerdo a la presencia de rotura, tamaño y/o loculaciones del absceso, combinando antibioticoterapia con métodos de drenaje quirúrgico mínimamente invasivos. Se contrasta y discute la bibliografía disponible, destacando la necesidad de investigaciones actualizadas en Chile.

Liver abscess has low incidence but high mortality. Its diagnosis is often delayed due to the variability of clinical presentations. We present three cases in women, two of which manifested with a febrile syndrome with unspecified microbiology, while the third presented with septic shock secondary to cholangitis, with Escherichia coli isolated. All cases were managed with empirical intravenous antibiotic therapy and surgical drainage, one through laparoscopy, two through percutaneous methods, and one associated with endoscopic retrograde cholangiopancreatography. The therapeutic approach is determined based on the presence of rupture, size, and/or loculations of the abscess, combining antibiotic therapy with minimally invasive surgical drainage methods. We discuss the available literature, emphasizing the need for updated research in Chile.

Hepatectomía derecha de urgencia por necrosis hepática infectada secundaria a colangiografía endoscópica / Urgent right hepatectomy for infected hepatic necrosis secondary to endoscopic cholangiography

RESUMEN El hematoma subcapsular hepático es una complicación infrecuente pero potencialmente grave de la colangiografía retrógrada endoscópica. Por otra parte, las complicaciones derivadas del hematoma pueden ser su rotura, con el consiguiente sangrado masivo, y/o la trombosis portal por compresión que evolucione hacia la necrosis, la cual es susceptible de infecciones generalmente graves que requieren un manejo más enérgico. Presentamos el caso de una paciente a quien se le realizó una colangiografía endoscópica retrógrada por una colangitis aguda, y presentó en la evolución un hematoma subcapsular, que progresó a la necrosis hepática por compresión del pedículo portal, y una infección de esa necrosis, por lo que requirió una hepatectomía derecha de urgencia.

ABSTRACT Hepatic subcapsular hematoma is a rare but potentially lethal complication of endoscopic retrograde cholangiography. On the other hand, complications derived from the hematoma can be its rupture with the consequent massive bleeding, and/or portal thrombosis due to compression that evolves towards necrosis, which is susceptible to generally serious infections that require more aggressive management. We present the case of a patient treated in our department who underwent retrograde endoscopic cholangiography as treatment for her acute cholangitis, presenting in the evolution a subcapsular hematoma that progressed to hepatic necrosis due to compression of the portal pedicle and later an infection of that necrosis. requiring an emergency right hepatectomy as surgical treatment.

Aplicabilidad del índice de fragilidad hepática en pacientes cirróticos evaluados para trasplante / Applicability of the liver frailty index in cirrhotic patients evaluated for transplantation

Introducción. En las últimas décadas se han desarrollado diferentes scores y modelos para predecir el pronóstico en pacientes con enfermedad hepática crónica avanzada. Los más reconocidos y utilizados son el sistema de estadificación de Child-Pugh (CP) y el score de MELD, pero estos carecen de herramientas para evaluar objetivamente otros factores pronósticos. Por este motivo, se ha incorporado el concepto de fragilidad a la hepatología clínica. El objetivo de este artículo es examinar la aplicabilidad del índice de fragilidad hepática (IFH) en pacientes con cirrosis evaluados para trasplante hepático en Uruguay. Metodología. Estudio observacional, descriptivo y retrospectivo en el Servicio de Enfermedades Hepáticas del Hospital Central de las Fuerzas Armadas (HCFFAA) de enero de 2018 a diciembre de 2021. Resultados. Se evaluaron un total de 78 pacientes, excluyéndose 19 de estos, culminando con una muestra final de 59 pacientes. La edad media fue de 52 años, siendo el 66 % hombres. La principal etiología de la cirrosis fue la alcohólica, y la comorbilidad más frecuente fue el sobrepeso/obesidad (66 %). La media de IFH fue de 4,03 ± 0,45. El 90 % de los pacientes eran prefrágiles, el 10 % frágiles y ningún paciente fue clasificado como no frágil. El 76 % presentaba un estadio avanzado de la enfermedad al momento de la evaluación 42 % CP estadio B, 34 % CP C, 24 % CP A, con una media de MELD-Na de 17,8 ± 7,6. El 17 % tuvo complicaciones infecciosas. La mortalidad global (n=78) fue del 12 %, y la de los pacientes con IFH calculado fue del 22 %. Conclusiones. El cálculo del IFH es realizable en cirróticos como herramienta objetiva que brinda una mirada integral del paciente. A mayor severidad de la cirrosis, mayor es el IFH. Sin embargo, este índice no parece ser un predictor de la eventual realización del trasplante hepático, ni de muerte en lista de espera en nuestros pacientes.

Introduction. In recent decades, several scores and models have been proposed to predict prognosis in patients with advanced chronic liver disease. The most recognized and used are the Child-Pugh (CP) and the Model for End-stage Liver Disease (MELD) scores, but they lack tools to objectively evaluate other prognostic factors. For this reason, the concept of fragility has been incorporated into clinical hepatology. The objective of this study was to evaluate the applicability of the liver frailty index (LFI) in patients with cirrhosis evaluated for liver transplantation in Uruguay. Methodology. Observational, descriptive and retrospective study at the Hospital Central de las Fuerzas Armadas (HCFFAA) Liver Disease Service from January 2018 to December 2021. Results. A total of 78 patients were evaluated, 19 were excluded, culminating in a final sample of 59 patients. The mean age was 52 years, with 66% being men. The main etiology of cirrhosis was alcoholic and the most frequent comorbidity was overweight/obesity (66%). The mean LFI was 4.03 ± 0.45. 90% of patients were pre-fragile, 10% were fragile, and no patient was classified as non-fragile. 76% had an advanced stage of the disease at the time of evaluation: 42% CP stage B, 34% CP C, 24% CP A, with a mean MELD-Na of 17.8 ± 7.6. 17% had infectious complications. Overall mortality (n=78) was 12%, and that of patients with calculated LFI was 22%. Conclusions. The LFI can be calculated in cirrhotic patients, and it is an objective tool that provides a comprehensive view of the patient. LFI depends on the severity of the cirrhosis. However, this index is not a predictor of liver transplantation or death on the waiting list in our patients.

Neoplasia quística mucinosa hepática, reporte de un caso y análisis de la patología / Hepatic mucinous cystic neoplasm, case report and pathology analysis / Neoplasia cística mucinosa hepática, relatório de um caso e análise da patologia

Desde los primeros reportes en la bibliografía, la nomenclatura de las lesiones quísticas hepatobiliares se ha ido modificando, habiéndose descripto dos tipos de lesiones: las serosas y las mucinosas. En 2010 la Organización Mundial de la Salud estableció una nueva clasificación donde los términos cistoadenomas y cistoadenocarcinomas hepatobiliares son reemplazados por entidades más específicas como la neoplasia mucinosa quística y los tumores quísticos intraductales (neoplasia papilar intraductal, neoplasma tubulopapilar intraductal y neoplasma oncocitico papilar). En cuanto a la neoplasia mucinosa quística, la presencia de estroma ovárico le confiere características distintivas en lo patológico y biológico, siendo esto un requisito en la clasificación de la OMS. Esta característica lo diferencia de los hamartomas biliares, los quistes congénitos y la enfermedad de Caroli. Dichas neoplasias son infrecuentes, con una incidencia menor al 5% de las lesiones quísticas hepáticas y ocurren casi exclusivamente en mujeres, frecuentemente perimenopáusicas. Su potencial de malignización ha sido descrito, siendo éste la indicación de tratamiento quirúrgico resectivo. Presentamos el caso clínico de una paciente portadora de una neoplasia quística mucinosa hepática, catalogada como cistoadenoma hepático según la antigua clasificación.

Since the early reports in the literature, the nomenclature of hepatobiliary cystic lesions has been modified, with two types of lesions being described: serous and mucinous. In 2010, the World Health Organization established a new classification in which the terms hepatobiliary cystadenomas and cystadenocarcinomas were replaced by more specific entities such as mucinous cystic neoplasms and intraductal cystic tumors (intraductal papillary neoplasm, intraductal tubulopapillary neoplasm, and intraductal oncocytic papillary neoplasm). Regarding mucinous cystic neoplasms, the presence of ovarian stroma confers distinctive pathological and biological characteristics, which is a requirement in the WHO classification. This characteristic differentiates it from biliary hamartomas, congenital cysts, and Caroli's disease. Such neoplasms are rare, with an incidence of less than 5% of hepatic cystic lesions, and occur almost exclusively in women, often perimenopausal. Their potential for malignancy has been described, and this is the indication for surgical resection treatment. We present a clinical case of a patient with a mucinous cystic hepatic neoplasm, classified as a hepatic cystadenoma according to the old classification.

Desde os primeiros relatos na literatura, a nomenclatura das lesões císticas hepatobiliares tem sido modificada, sendo descritos dois tipos de lesões,asserosas e as mucinosas. Em 2010, a Organização Mundial da Saúdeestabeleceuuma nova classificação, naqual os termos cistoadenomas e cistoadenocarcinomas hepatobiliares foramsubstituídos por entidades mais específicas, como a neoplasia mucinosa cística e os tumores císticos intraductais (neoplasia papilar intraductal, neoplasma tubulopapilar intraductal e neoplasma oncocítico papilar). Em relação à neoplasia mucinosa cística, a presença de estroma ovarianoconfere características distintas do ponto de vista patológico e biológico, sendoesseum requisito naclassificação da OMS. Essa característica a diferencia dos hamartomas biliares, cistoscongênitos e doença de Caroli. Essas neoplasias são raras, comumaincidência menor que 5% das lesões císticas hepáticas, e ocorremquase exclusivamente em mulheres, frequentementeperimenopáusicas. Seu potencial de malignizaçãotem sido descrito, sendoesta a indicação para tratamentocirúrgicoressectivo. Apresentamos o caso clínico de uma paciente portadora de uma neoplasia cística mucinosa hepática, classificada como cistoadenoma hepático de acordocom a antigaclassificação.

Regressão espontânea do carcinoma hepatocelular: foco nos fatores de risco associados / Spontaneous regression of hepatocellular carcinoma: focusing in the associated risk factors

ABSTRACT Background: Spontaneous regression (SR) is defined as the partial or complete disappearance of a tumor, in the absence of a specific treatment. Evidence of the SR in hepatocellular carcinoma (HCC) is rare. Objective: The authors aimed to review all the cases of SR of HCC in two reference centers of Southern Brazil, highlighting the main characteristics. Methods: Data of all patients with HCC were retrospectively reviewed looking for the occurrence of SR in patients from two tertiary centers in Southern Brazil, in the last five years. The diagnosis of cirrhosis was established according to clinical, laboratory and imaging data, as well as upper endoscopy or histopathological examination when necessary. The diagnosis of HCC was based on typical findings according to radiologic criteria (LIRADS) or histopathological examination. Spontaneous regression was defined as a partial or complete involution of a HCC in the absence of a specific therapy. Results: From all cases of HCC in the last 5 years (n=433), there were five cases of SR. Three (60%) were men, the mean age was 62.6 (50.0-76.0) years, and the etiology was HCV in 3 (60%). Complete regression was observed in three patients (60%), one patient (20%) presented partial regression, and one (20%) relapesed and died. The time of follow-up varied between 12 and 21 months. In this presentation, it was highlighted one case of SR observed after COVID-19 infection in a patient with cirrhosis. The possible mechanisms involved in this situation were reviewed, emphasizing the most common like hypoxia and immunological. There were also one patient submitted to a surgical procedure as a possible fator involved and three patients without obvious risk factors. Conclusion: This phenomenon will possibly contribute to a better understanding of the pathophysiological mechanisms of HCC.

RESUMO Contexto: A evidência da regressão espontânea (RE) no carcinoma hepatocelular (CHC) é rara. Objetivo: Revisar todos os casos de RE de CHC em dois centros de referência do Sul do Brasil, destacando as principais características. Métodos: Os dados de todos os pacientes com CHC foram revisados retrospectivamente buscando a ocorrência de RE em pacientes de dois centros terciários do Sul do Brasil, nos últimos 5 anos. O diagnóstico de cirrose foi estabelecido de acordo com dados clínicos, laboratoriais e de imagem, além de endoscopia digestiva alta ou exame histopatológico quando necessário. O diagnóstico de CHC foi baseado em achados típicos de acordo com critérios radiológicos (LIRADS) ou exame histopatológico. A RE foi definida como uma involução parcial ou completa de um CHC na ausência de terapia específica. Resultados: Do total de casos de CHC nos últimos 5 anos (n=433), houve cinco casos de RE. Três (60%) eram homens, a média de idade foi de 62,6 (50,0-76,0) anos, a etiologia foi virus da hepatite C em 3 (60%). A regressão completa foi observada em três pacientes (60%), um paciente (20%) apresentou regressão parcial e um (20%) apresentou recidiva e evoluiu a óbito. O tempo de seguimento variou entre 12 e 21 meses. Nesta apresentação foi destacado um caso (20%) de RE observado após infecção por COVID-19 em paciente com cirrose. Foram revisados os possíveis mecanismos envolvidos nesta situação, enfatizando os mais comuns como hipóxia e imunológicos. Houve também um paciente submetido a procedimento cirúrgico como possível fator envolvido e três pacientes sem fatores de risco evidentes. Conclusão: Este fenômeno possivelmente contribuirá para uma melhor compreensão dos mecanismos fisiopatológicos do CHC.

Desarrollo de una Unidad de Cirugía Hepatobiliar Compleja y Trasplante Hepático en un hospital público: a una década de su formación / Development of a complex hepatobiliary surgery and liver transplantation unit in a public hospital: a decade after its creation

RESUMEN Antecedentes: concentrar esta patología hepatobiliar en centros especializados puede permitir bajas cifras de morbimortalidad y mejores resultados alejados. Objetivo: describir las características clínico-patológicas y los resultados de una serie de pacientes operados en los primeros 10 años de una Unidad de Cirugía Hepatobiliar Compleja y Trasplante Hepático (TH), así como la actividad científica y docente de sus integrantes. Materiales y métodos: estudio retrospectivo descriptivo. Se recopiló información de una base de datos prospectiva. Se clasificaron los procedimientos según su complejidad y se analizaron los TH, las hepatectomías y los procedimientos biliares complejos, realizados entre 2013 y 2022. Resultados: sobre 1440 procedimientos quirúrgicos, 832 fueron de alta complejidad (58%). Se realizaron 452 trasplantes hepáticos (TH), 14 (3%) de ellos hepatorrenales; la sobrevida global del trasplante fue de 83%, 77% y 75% a 1, 3 y 5 años, respectivamente. La falla primaria del injerto se observó en 5 casos (1,1%). Se efectuaron 254 hepatectomías: 58 (23%) por patología benigna, 155 (61%) por patología maligna y 41 (16%) en donante vivo relacionado para TH. La morbilidad total fue del 27% y la mortalidad intrahospitalaria de 2%. Se efectuaron 106 derivaciones biliodigestivas: 53 en pacientes con lesión quirúrgica de la vía biliar. La morbilidad a 30 días fue del 42%, en su mayoría complicaciones menores (28%). Además, se realizaron 17 duodenopancreatectomías cefálicas y 3 esplenopancreatectomías. Se realizaron múltiples publicaciones, presentaciones y cursos, y desde 2015 se implementó una residencia posbásica de la especialidad. Conclusión: la concentración de patología hepatobiliar en un centro de alta complejidad permitió alcanzar resultados satisfactorios, comparables con series extranjeras.

ABSTRACT Background: Centralizing hepatobiliary disease in specialized centers can reduce morbidity and mortality rates and improve long-term outcomes. Objective: The aim of the present study was to describe the clinical and pathological features and surgical outcomes of a series of patients operated on in the Hepatobiliary Surgery and Liver Transplantation Unit of Hospital El Cruce during its first 10 years, as well as the scientific and educational activity of its members. Material and methods: We conducted a descriptive and retrospective study. The information was retrieved from a prospective database. The procedures were classified according to their complexity. An analysis was conducted on liver transplantations (LTs), liver resections and complex biliary procedures, performed from 2013 to 2022. Results: Of 1449 surgical procedures, 832 were high-complexity interventions (58%). A total of 452 LTs were performed, 14 (3%) were combined liver and kidney transplantations; overall transplant survival was 83%, 77% and 75% at 1, 3 and 5 years, respectively. Primary graft dysfunction was observed in 5 cases (1.1%). There were 254 liver resections; 58 cases (23%) were related to benign liver diseases, 155 (61%) to malignancies, and 41 (16%) were associated with living donor transplants. Overall morbidity was 27% and in-hospital mortality was 2%. A total of 106 bilio-digestive bypass procedures were carried out, 53 in patients with bile duct injury. Thirty-day morbidity was 42%, and most cases were minor complications (28%). Other procedures included 17 cephalic pancreaticoduodenectomies and 3 splenectomies and distal pancreatectomies. We have published numerous papers, delivered presentations and courses, and implemented a fellowship program in the specialty since 2015. Conclusion: Centralizing hepatobiliary diseases at a high-complexity center led to comparable outcomes with those reported in international series.

Infecciones bacterianas durante el primer mes post trasplante hepático. Experiencia de 12 años en un único centro. Montevideo-Uruguay / Bacterial infections during the first month after liver transplantation. 12 years experience in a single center. Montevideo-Uruguay

INTRODUCCIÓN: Las infecciones bacterianas en trasplante hepático (TH) son una de las principales causas de morbimortalidad. OBJETIVO: Caracterizar las complicaciones infecciosas bacterianas en el primer mes postrasplante. Pacientes y MÉTODOS: Estudio retrospectivo entre los años 2009-2020. RESULTADOS: 225 pacientes recibieron un TH. 80 (35,5%) desarrollaron al menos un episodio de infección bacteriana en el primer mes postrasplante hepático. Hubo 105 episodios de infección bacteriana con una incidencia de 46,6%. El foco más frecuente fue el abdominal (48,6%) y el microorganismo predominante fue Klebsiella spp. De los 104 aislamientos, el 57,6% presentaron un perfil MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron menor sobrevida al alta hospitalaria en comparación con los que no la presentaron 87,5 versus 94,5% [OR 4,18 (IC 95%: 1,5-11,6)]. En el análisis multivariado la reintervención quirúrgica precoz [OR 4,286 (IC 95%: 1,911-9,61)], mostró un riesgo significativo de desarrollar una complicación infecciosa bacteriana en el primer mes postrasplante. CONCLUSIONES: Tres de cada 10 pacientes presentaron una infección bacteriana en el primer mes postrasplante con una alta incidencia de bacilos gramnegativos MDR/XDR. Los pacientes que desarrollaron una complicación infecciosa presentaron una menor sobrevida al alta. La reintervención quirúrgica precoz se identificó como un factor predisponente de infección temprana.

BACKGROUND: Bacterial infections are one of the main causes of morbidity and mortality in liver transplant recipients (LT). Aim: To characterize bacterial infectious complications in the first month an after a liver transplant. METHODS: Retrospective analysis of a cohort of liver transplant recipients who presented at least one bacterial infectious complication in the first month after transplant between 2009 and 2020. RESULTS: 225 patients were analyzed. 80 (35.5%) had a least one documented bacterial infection during the first month after transplant. 105 bacterial infections were documented, with an incidence of 46.6%. The most frequent origin was intra-abdominal (48.6%) and the predominant isolated microorganism was Klebsiella spp. Among 104 isolated microorganisms 57.6% showed MDR/XDR profile. Patients who developed a bacterial infectious complication had a shorter overall survival (OS) after discharge from hospital (87.5% vs 94.5%) [OR 4.18 (IC 95%: 1.5-11,6)]. When multivariate analysis of predisposing factors was performed early surgical reoperation was the only variable associated with an increased risk of developing a bacterial complication in the first month [OR 4.286 (IC 95%: 1.911-9.61)]. CONCLUSIONS: Three out of 10 patients developed a bacterial infectious complication during the first month after liver transplant with a high incidence of gram-negative bacillus MDR/XDR. Patients who presented infectious complications had a shorter OS after discharge, and early reoperation was identified as a predisposing factor of early infectious complications.

Massive pleural empyema secondary to amoebic liver abscess in a child / Empiema pleural masivo secundario a absceso hepático amebiano en un niño

Abstract Background: Pleural empyema secondary to a ruptured amoebic liver abscess is a rare complication in the pediatric population. Case report: We report the case of a 13-year-old male with right flank abdominal pain, productive cough with foul-smelling sputum, fever, and respiratory distress. Physical examination revealed breathlessness, decreased vesicular murmur in the right hemithorax, abdominal distension, hepatomegaly, and lower limb edema. Laboratory tests revealed mild anemia, leukocytosis without eosinophilia, elevated alkaline phosphatase, hypoalbuminemia, and positive immunoglobulin G antibodies against Entamoeba histolytica in pleural fluid. He required a chest tube and treatment with metronidazole. After 2 months of follow-up, the abscesses disappeared, and the empyema decreased. Conclusions: Massive pleural empyema secondary to a ruptured liver abscess is a rare complication. The epidemiological link associated with the symptoms and serological tests can help in the diagnosis.

Resumen Introducción: El empiema pleural secundario a ruptura de absceso amebiano hepático es una complicación poco frecuente en la población pediátrica. Caso clínico: Se reporta el caso de un paciente de sexo masculino de 13 años que presentó dolor abdominal en flanco derecho, tos productiva con esputo de mal olor, fiebre y dificultad respiratoria. Al examen físico se encontró amplexación y murmullo vesicular disminuido en hemitórax derecho, distensión abdominal, hepatomegalia y edema de miembros inferiores. Los resultados del laboratorio evidenciaron anemia leve, leucocitosis sin eosinofilia, elevación de fosfatasa alcalina, hipoalbuminemia y anticuerpos IgG contra Entamoeba histolytica positivo en líquido pleural. Requirió tubo de drenaje torácico y tratamiento con metronidazol. A los dos meses de seguimiento los abscesos desaparecieron y el empiema disminuyó. Conclusiones: El empiema pleural masivo secundario a ruptura de absceso hepático es una complicación poco frecuente. El nexo epidemiológico asociado con la sintomatología y pruebas serológicas pueden ser de ayuda en el diagnóstico.

Sofosbuvir más glecaprevir/pibrentasvir como terapia de rescate postrasplante hepático en pacientes con exposición previa a inhibidores de NS5A. Serie de casos / Sofosbuvir plus glecaprevir/pibrentasvir as salvage therapy after liver transplantation in NS5A inhibitor-experienced patients. A case series

Resumen Antecedentes: El tratamiento de la infección crónica por el virus de la hepatitis C (VHC) con antivirales de acción directa logra tasas de respuesta virológica sostenida superiores a 95 %. Sin embargo, el manejo del fracaso virológico sigue siendo un desafío clínico y la evidencia sobre el retratamiento es limitada, especialmente en poblaciones como los receptores de trasplante hepático (TH). Objetivo: Este estudio evaluó el régimen de sofosbuvir más glecaprevir/pibrentasvir (GLE/PIB) en receptores de TH en quienes falló el régimen basado en inhibidores de la proteína no estructural 5A (NS5A). Material y métodos: Estudio retrospectivo de 111 pacientes trasplantados entre enero de 2018 y diciembre de 2020; 18 pacientes presentaron infección recurrente por VHC posterior al TH, tres de ellos tuvieron antecedentes de al menos un régimen basado en inhibidores de NS5A. Se inició terapia de rescate con sofosbuvir más GLE/PIB durante 12 semanas posterior al TH; se registraron las características basales de los pacientes y sus desenlaces. Resultados: En los tres pacientes se logró obtener una carga viral indetectable de VHC a las 12 semanas de finalizar el tratamiento. No se observaron eventos adversos graves. Conclusión: En nuestra serie, sofosbuvir más GLE/PIB durante 12 semanas demostró ser una terapia de rescate efectiva y segura posterior al TH en pacientes previamente tratados con inhibidores de NS5A.

Abstract Background: Treatment of chronic hepatitis C virus (HCV) infection with direct-acting antivirals achieves a sustained virologic response rates higher than 95%. However, virologic failure remains a clinical challenge, and data on retreatment are limited, especially in special populations such as liver transplant (LT) recipients. Objective: This study evaluated the sofosbuvir plus glecaprevir-pibrentasvir (GLE/PIB) regimen in LT recipients who had failed to a nonstructural protein 5A (NS5A) inhibitor-based regimen. Material and methods: Retrospective study of 111 liver transplant recipients between January 2018 and December 2020; 18 patients presented with HCV recurrent infection after LT, out of whom three had a history of at least one NS5A inhibitor-based regimen. Salvage therapy with sofosbuvir plus GLE/PIB was started for 12 weeks; baseline characteristics and outcomes were recorded. Results: All three patients (100%) achieved an undetectable HCV viral load 12 weeks after treatment completion. No serious adverse events were observed. Conclusion: In our series, sofosbuvir plus GLE/PIB for 12 weeks is an effective and safe salvage therapy after LT in patients previously treated with NS5A inhibitors.

Trasplante hepático por hemangioendotelioma hepático difuso / Liver transplantation for diffuse epithelioid hemangioendothelioma

RESUMEN El hemangioendotelioma epiteloide hepático (HEH) es un tumor vascular, de etiología no aclarada, extraordinariamente infrecuente. La ausencia de características clínicas, analíticas y radiológicas especificas dificulta su correcto diagnóstico. El tratamiento del HEH depende del tamaño y localización tumoral, la extensión extrahepática y la condición médica del paciente. Entre las posibles opciones se encuentra el trasplante hepático, que obtiene unos buenos resultados clínicos, aunque el riesgo de recidiva no es despreciable. Presentamos un nuevo caso de HEH tratado mediante trasplante hepático.

ABSTRACT Hepatic epithelioid hemangioendothelioma (HEHE) is an extremely rare vascular tumor of unclear etiology. The diagnosis is difficult due to the absence of specific clinical characteristics, laboratory tests results and radiological findings. The management of HEHE depends on tumor size, location, extrahepatic extension, and patients' medical status. Liver transplantation is one of the possible options with good clinical results, although the risk of recurrence is not negligible. We present a new case of HEHE managed with liver transplantation.

Sífilis congénita e infarto hepático, una asociación no reportada. Descripción de un caso pediátrico / Congenital syphilis and hepatic infarction, a not previously reported association. A pediatric case report

La sífilis congénita es causada por la infección del feto con Treponema pallidum durante el embarazo. Los síntomas son variables. Si bien es común el daño endotelial, no suele estar presente en los casos congénitos. Reportamos el caso de un lactante de 42 días de vida hospitalizado por masa abdominal. Las imágenes confirmaban la presencia de una lesión en el lóbulo hepático izquierdo sin efecto de masa. Las biopsias mostraron cambios compatibles con infarto y hepatitis neonatal. Las serologías del paciente y de su madre confirmaron el diagnóstico de sífilis congénita, y recibió tratamiento con penicilina intravenosa. El hígado se encuentra protegido de los daños isquémicos gracias a su doble irrigación, pero la acumulación de noxas puede haber provocado dicha presentación inusual. Tres meses más tarde, el paciente se encontraba libre de síntomas y la resonancia de control mostró atrofia del lóbulo izquierdo, mientras el resto del parénquima no presentaba alteraciones.

Congenital syphilis is caused by Treponema pallidum infection of the fetus during pregnancy. Symptoms are variable. While endothelial damage is common, it is not usually present in congenital cases. Here we report the case of a 42-day-old infant hospitalized due to an abdominal mass. Imaging studies confirmed the presence of an injury in the left lobe of the liver without mass effect. Biopsies showed changes compatible with infarction and neonatal hepatitis. The patient's and his mother's serologies confirmed the diagnosis of congenital syphilis, and he was treated with intravenous penicillin. The liver protected from ischemic injury by its double irrigation, but the accumulation of harmful agents may have caused this unusual presentation. Three months later, the patient was symptom-free, and the control MRI showed atrophy of the left lobe, while the rest of the parenchyma was unchanged.

Diagnóstico por imagen de abscesos hepáticos y pulmonares por estreptococos del grupo viridans. Presentación de caso / Imaging diagnosis of liver and lung abscesses due to viridans streptococci. Case presentation

Resumen El Streptococcus viridans es conocido más comúnmente como agente infeccioso en las endocarditis, sin embargo, poco se conoce sobre su potencial infeccioso en otros órganos o sistemas, donde ha demostrado una elevada mortalidad. El reconocimiento del Streptococcus viridans como agente productor de abscesos en otras localizaciones como a nivel hepático o pulmonar, permitirá un diagnóstico oportuno mediante los distintos métodos de imagen, reduciendo las graves consecuencias para el paciente y los tiempos de hospitalización. Se presenta el caso de un paciente del sexo masculino de 33 años de edad sin antecedentes crónico degenerativos, que inició con sintomatología 7 meses previos a su ingreso, con fiebre intermitente, fatiga, astenia, anorexia y pérdida de peso. A la exploración física presentó dolor a la palpación media y profunda en hipocondrio derecho, en el panel de laboratorios presentó llamativa neutrofilia, en la tomografía de tórax y abdomen se mostró lesión cavernomatosa en pulmón y quistes complicados hepáticos, a los cuales se les realizó drenaje percutáneo guiado por ultrasonido, con envío de muestras a cultivo con resultado positivo para Streptococcus viridans, lo que permitió brindar el tratamiento dirigido al paciente, y que remitiera la enfermedad.

Abstract Streptococcus viridans is more commonly known as an infectious agent in endocarditis, however, little is known about its infectious potential in other organs or systems, where it has shown high mortality. The recognition of Streptococcus viridans as an abscess-producing agent in other locations, such as the liver or lungs, will allow timely diagnosis using different imaging methods, reducing serious consequences for the patient and hospitalization times. We present the case of a 33-year-old male patient with no chronic degenerative history, who started symptoms 7 months prior to admission, with intermittent fever, fatigue, asthenia, anorexia and weight loss, on physical examination he presented pain at the medium and deep palpation in the right hypochondrium, in the laboratory panel I present striking neutrophilia, in the tomography of the thorax and abdomen a cavernous lesion in the lung and complicated hepatic cysts are shown, to which percutaneous drainage guided by ultrasound is performed, with sending of cultured samples with a positive result for Streptococcus viridans. Thus, allowing treatment to be provided to the patient, thereby achieving remission of the disease.

Caracterização clínica e patológica dos linfomas hepáticos: um estudo retrospetivo unicêntrico / Clinical and pathological characterization of hepatic lymphomas: a retrospective single-center study

ABSTRACT Background: The incidence of hepatic lymphoma has been increasing recently and diagnosis can be challenging as clinical presentation and radiological findings are usually variable and non-specific. Objective The aims of this study were to describe their main clinical, pathological and imaging characteristics and identify poor prognostic factors. Methods A retrospective study that included all patients with histological diagnosis of liver lymphoma over a 10-year period at our center was performed. Results A total of 36 patients were identified, with mean age of 56.6 years and male predominance (58%). There were three patients with primary liver lymphoma (8.3%) and 33 with secondary liver lymphoma (91.7%). The most common histological type was diffuse large B-cell lymphoma (33.3%). The most common clinical manifestations included fever, lymphadenopathy, weight loss, night sweats and abdominal discomfort; three patients (11.1%) were asymptomatic. Computed tomography scan revealed heterogenous radiological patterns including a single nodule (26.5%), multiple nodules (41.2%) or diffuse infiltration (32.4%). The mortality rate during follow-up was 55.6%. Higher levels of C-reactive protein (P=0.031) and absence of treatment response (P<0.001) were significantly associated with higher mortality. Conclusion Hepatic lymphoma is a rare disease that may involve liver as part of a systemic disease or, less commonly, be confined to this organ. Clinical presentation and radiological findings are often variable and non-specific. It is associated with high mortality and poor prognostic factors include higher levels of C-reactive protein and absence of response to treatment.

RESUMO Contexto A incidência de linfoma hepático tem aumentando recentemente e o diagnóstico pode ser desafiante, na medida em que a apresentação clínica e os achados imagiológicos são geralmente variáveis e inespecíficos. Objetivo: Os objetivos deste estudo foram descrever suas principais características clínicas, patológicas e de imagem e identificar fatores de mau prognóstico. Métodos: Foi realizado um estudo retrospetivo que incluiu todos os pacientes com diagnóstico histológico de linfoma hepático num período de 10 anos no nosso centro. Resultados: Foram identificados 36 pacientes, com média de idade de 56,6 anos e predomínio de género masculino (58%). Havia três pacientes com linfoma hepático primário (8,3%) e 33 com linfoma hepático secundário (91,7%). O tipo histológico mais comum foi o linfoma difuso de grandes células B (33,3%). As manifestações clínicas mais comuns incluíram febre, linfadenopatia, emagrecimento, hipersudorese noturna e desconforto abdominal; 3 (11,1%) pacientes eram assintomáticos. A tomografia computadorizada revelou padrões radiológicos heterogêneos, incluindo um único nódulo (26,5%), múltiplos nódulos (41,2%) ou infiltração difusa (32,4%). A taxa de mortalidade durante o seguimento foi de 55,6%. Níveis mais elevados de proteína C reativa (P=0,031) e ausência de resposta ao tratamento (P<0,001) foram significativamente associados a maior mortalidade. Conclusão O linfoma hepático é uma doença rara que pode envolver o fígado como parte de uma doença sistêmica ou, menos comumente, estar confinado a este órgão. A apresentação clínica e os achados radiológicos são frequentemente variáveis e inespecíficos. Associa-se a elevada mortalidade e fatores de mau prognóstico incluem níveis mais elevados de proteína C reativa e ausência de resposta ao tratamento.

Uso del esquema Scottish and Newcastle Anti-Emetic Pretreatment (SNAP) en la recuperación de una intoxicación por sobredosis masiva de acetaminofén (paracetamol) con injuria hepática aguda - Reporte de caso

Acetaminophen is a drug widely used in the world and easily accessible due to its antipyretic, analgesics characteristics, among others (1); however, exposure to toxic doses causes organic damage and even death. We present the case of an 18-year-old female patient who ingested 40 grams of acetaminophen and developed severe liver dysfunction, being treated with N-acetylcysteine (NAC) antidotal therapy according to the simplified scheme: Scottish and Newcastle Anti-emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presenting improvement in the clinical course and decrease in liver profiles, coagulation disorder, INR and resolution of the condition.

El acetaminofén es un fármaco ampliamente usado en el mundo y de fácil acceso por sus características antipiréticas, analgésicas, entre otras (1); sin embargo la exposición a dosis tóxicas produce daños a nivel orgánico e incluso la muerte. Presentamos el caso de una paciente mujer de 18 años que ingirió 40 gramos de acetaminofén y desarrolló injuria hepática severa, siendo tratada con terapia antidotal de N-acetilcisteína (NAC) según el esquema simplificado: Scottish and Newcastle Anti-Emetic Pretreatment Paracetamol Poisoning Study Regimen (SNAP), presentando mejoría del curso clínico y disminución de los perfiles hepáticos, trastorno de coagulación, INR y resolución del cuadro.

Endoftalmitis endógena por Klebsiella pneumoniae: reporte de 2 casos y revisión de literatura referente a K. pneumoniae hipermucoviscosa e hipermucovirulenta / Endogenous Klebsiella pneumoniae endophthalmitis: report of 2 cases and literature review regarding hypermucoviscous and hypermucovirulent K. pneumoniae

Objetivo: Reportar dos casos de endoftalmitis endógena por Klebsiella pneumoniae hipermucoviscosa y revisar las características clínicas de esta entidad que ha aumentado su prevalencia en países occidentales. Observaciones: Dos pacientes fueron diagnosticados con endoftalmitis endógena por K. pneumoniae con confirmación microbiológica de un origen abdominal, uno de ellos por un absceso hepático y el otro por un absceso renal. Ambos pacientes fueron sometidos a vitrectomía precoz, y a antibióticos intravítreos/intravenosos, no obstante uno requirió evisceración y el otro presentó una agudeza visual de percepción de luz. Conclusiones e importancia: K. pneumoniae es la primera causa de endoftalmitis endógena en Asia oriental, pero es poco frecuente en los países occidentales. Sin embargo su prevalencia en esta última población parece estar aumentando en asociación con las variantes hipermucoviscosas e hipervirulentas de este microorganismo. La detección temprana y el tratamiento temprano de esta enfermedad son fundamentales para preservar la anatomía del ojo.

Objective: To report two cases of hypermucoviscous Klebsiella pneumoniae endogenous endophthalmitis and to review the clinical characteristics of this aggressive disease whose prevalence appears to be increasing in western countries. Observations: Two patients were diagnosed with K. pneumoniae endogenous endophthalmitis with microbiological confirmation of an abdominal source, one from a hepatic abscess and the other with a renal abscess. Both patients underwent early vitrectomy, and intravitreal/intravenous antibiotics, nonetheless one required evisceration and the other presented a postoperative visual acuity of light perception. Conclusions and importance: K. pneumoniae is the first cause of endogenous endophthalmitis in eastern Asia, but it is rare in western countries. Nevertheless, its prevalence in the latter population appears to be increasing in association with the hypermucoviscous and hypervirulent variants of this microorganism. The early detection and early management of this disease are pivotal to preserve the anatomy of the eye.

Bleeding hepatocellular adenoma: historical series and outcomes / Adenoma hepatocelular sangrante: série histórica e desfechos

ABSTRACT Introduction: hepatocellular adenoma - AHC - is a rare benign neoplasm of the liver more prevalent in women at reproductive age and its main complication is hemorrhage. In the literature, case series addressing this complication are limited. Methods: between 2010 and 2022, 12 cases of bleeding AHC were attended in a high-complexity university hospital in southern Brazil, whose medical records were retrospectively evaluated. Results: all patients were female, with a mean age of 32 years and a BMI of 33kg/m2. The use of oral contraceptives was identified in half of the sample and also half of the patients had a single lesion. The mean diameter of the largest lesion was 9.60cm and the largest lesion was responsible for bleeding in all cases. The presence of hemoperitoneum was documented in 33% of the patients and their age was significantly higher than the patients who did not have hemoperitoneum - 38 vs 30 years, respectively. Surgical resection of the bleeding lesion was performed in 50% of the patients and the median number of days between bleeding and resection was 27 days. In only one case, embolization was used. The relation between ingrowth of the lesions and the time, in months, was not obtained in this study. Conclusion: it is concluded that the bleeding AHC of the present series shows epidemiological agreement with the literature and may suggest that older patients trend to have hemoperitoneum more frequently, a fact that should be investigated in further studies.

RESUMO Introdução: o Adenoma Hepatocelular - AHC - é uma neoplasia benigna rara do fígado associada a mulheres com idade reprodutiva. Sua principal complicação é o sangramento,mas as séries de casos direcionadas a esta intercorrência são limitadas. Métodos: entre os anos de 2010 e 2022 foram registrados 12 casos de AHC sangrante em um hospital universitário de alta complexidade no sul do Brasil, cujos prontuários foram retrospectivamente avaliados. Resultados: todos os pacientes eram do sexo feminino, com média de idade de 32 anos e de IMC de 33kg/m2. O uso de anticoncepcionais foi identificado em metade da amostra e também metade das pacientes apresentava lesão única. O diâmetro médio da maior lesão foi de 9,60cm e a maior lesão foi responsável pelo sangramento em todos os casos. Hemoperitôneo foi documentado em 33% das pacientes e a idade destas foi significativamente maior do que as pacientes que não apresentaram hemoperitôneo - 38 vs 30 anos, respectivamente. A ressecção cirúrgica da lesão sangrante foi realizada em 50% das pacientes e a mediana de dias entre o sangramento e a ressecção foi de 27 dias. Em apenas um caso foi lançado mão da embolização da lesão. Não se demonstrou correlação entre a taxa de redução das lesões e o passar dos meses, nos casos em que foi adotado tratamento conservador. Conclusão: conclui-se que aos AHC sangrantes da presente série apresentam concordância epidemiológica com a literatura e pode sugerir que as pacientes com maior idade tendem a apresentar hemoperitôneo mais frequentemente, fato que deve ser investigado em maiores estudos.

Diabetes Mellitus Y Su Manejo En Escenarios Difíciles / Diabetes mellitus and its management in difficult scenarios

Introducción: la diabetes mellitus se produce por la alteración en el metabolismo de los carbohidratos, su prevalencia viene en aumento debido al incremento en la tasa de obesidad y los cambios en los hábitos nutricionales. En Colombia, alrededor de 8,36 % de la población padece diabetes tipo 2 y menos del 1 % diabetes tipo 1. Metodología: se seleccionaron 51 artículos sobre diabetes y diferentes escenarios clínicos, publicados en su mayoría entre los años 2015-2021. Resultados: en los pacientes con enfermedad hepática crónica, se aumenta la resistencia a la insulina e intolerancia a la glucosa; por esto, deben ser tratados en primera instancia con metformina o insulinas. En los diabéticos el riesgo cardiovascular se incrementa tanto para infarto como para accidente cerebrovascular. En estos, se puede realizar tratamiento con metformina, empagliflozina, entre otros. Los pacientes con falla renal tienen mayor riesgo de hipoglicemia por el metabolismo prolongado de la insulina como consecuencia de la filtración glomerular, en estos son útiles medicamentos como liraglutide y sus similares. Conclusión: existen múltiples escenarios clínicos que se presentan en conjunto con la diabetes mellitus. Se deben tener en cuenta las múltiples comorbilidades de los pacientes al momento de instaurar un tratamiento y sus diferentes determinantes, para garantizar su efectividad.

Introduction: Diabetes mellitus is caused by alterations in carbohydrate metabolism and its prevalence is increasing due to the increase in the rate of obesity and changes in nutritional habits. In Colombia, about 8.36% of the population suffers from type 2 diabetes and less than 1% from type 1 diabetes. Methods: Fifty-one articles were selected, on diabetes and different clinical scenarios, mostly published between 2015-2021. Results: In patients with chronic liver disease, insulin resistance and glucose intolerance are increased; therefore, they should be treated in the first instance with Metformin or Insulin. In diabetics, cardiovascular risk is increased for both infarction and stroke. In these patients, treatment can be performed with Metformin, Empagliflozin, among others. Patients with renal failure have a higher risk of hypoglycemia due to prolonged insulin metabolism as a consequence of glomerular filtration; medications such as Liraglutide and similar drugs are useful in these patients. Conclusion: There are multiple clinical scenarios that occur in conjunction with diabetes mellitus. The multiple comorbidities of patients should be taken into account when instituting treatment and its different determinants to ensure the effectiveness of the treatment to be appropriate for the patients.
