RESUMO

Introducción. El tacrolimus es un medicamento inmunosupresor ampliamente usado en trasplante hepático, que presenta una gran variabilidad interindividual la cual se considera asociada a la frecuencia de polimorfismos de CYP3A5 y MDR-1. El objetivo de este estudio fue evaluar la frecuencia de los polimorfismos rs776746, rs2032582 y rs1045642 y su asociación con rechazo clínico y toxicidad farmacológica. Métodos. Se incluyeron pacientes inmunosuprimidos con tacrolimus a quienes se les realizó trasplante hepático en el Hospital San Vicente Fundación Rionegro entre 2020 y 2022, con supervivencia mayor a un mes. Se evaluaron las variables clínicas, rechazo agudo y toxicidad farmacológica. Se secuenciaron los genes de estudio mediante PCR, comparando la expresión o no en cada uno de los pacientes. Resultados. Se identificaron 17 pacientes. El 43 % de los pacientes se clasificaron como CYP3A5*1/*1 y CYP3A5*1/*3, entre los cuales se encontró asociación con aumento en la tasa de rechazo agudo clínico, al comparar con los pacientes no expresivos (100 % vs. 44 %, p=0,05); no hubo diferencias en cuanto a la toxicidad farmacológica u otros desenlaces. Se encontró el polimorfismo rs2032582 en un 50 % y el rs1045642 en un 23,5 % de los pacientes, sin embargo, no se identificó asociación con rechazo u otros eventos clínicos. Conclusiones. Se encontró una asociación entre el genotipo CYP3A5*1/*1 y CYP3A5*1/*3 y la tasa de rechazo clínico. Sin embargo, se requiere una muestra más amplia para validar estos datos y plantear modelos de medicina personalizada.


Introduction. Tacrolimus is an immunosuppressive drug widely used in liver transplantation, which presents great interindividual variability which is considered associated with the frequency of CYP3A5 and MDR-1 polymorphisms. The objective of this study was to evaluate the frequency of the rs776746, rs2032582 and rs1045642 polymorphisms and their association with clinical rejection and drug toxicity. Methods. Immunosuppressed patients with tacrolimus who underwent a liver transplant at the Hospital San Vicente Fundación Rionegro between 2020 and 2022 were included, with survival of more than one month. Clinical variables, acute rejection and pharmacological toxicity were evaluated. The study genes were sequenced by PCR, comparing their expression or not in each of the patients. Results. Seventeen patients were identified. 43% of the patients were classified as CYP3A5*1/*1 and CYP3A5*1/*3, among which an association was found with increased rates of clinical acute rejection when compared with non-expressive patients (100% vs. 44%, p=0.05). There were no differences in drug toxicity or other outcomes. The rs2032582 polymorphism was found in 50% and rs1045642 in 23.5% of patients; however, no association with rejection or other clinical events was identified. Conclusions. An association was found between the CYP3A5*1/*1 and CYP3A5*1/*3 genotype and the clinical rejection rate. However, a larger sample is required to validate these data and propose models of personalized medicine.

RESUMO

Introducción. La enfermedad hepática esteatósica asociada a disfunción metabólica (MASLD) se ha convertido en la enfermedad hepática crónica más frecuente en los países occidentales, causando un aumento en los costos y en la ocupación hospitalaria. La caracterización integral previa al trasplante hepático en pacientes con MASLD es una gran interrogante, especialmente en nuestro medio. El objetivo del presente estudio fue realizar la caracterización clínico-epidemiológica de pacientes trasplantados por cirrosis hepática (CH) descompensada o carcinoma hepatocelular (CHC) asociado a MASLD. Metodología. Se desarrolló un estudio observacional retrospectivo, descriptivo, de corte transversal en el Servicio de Hepatología del Hospital Pablo Tobón Uribe en Medellín, Colombia. Se incluyeron pacientes mayores de 17 años, con diagnóstico de CH o de CHC asociado a MASLD que fueron trasplantados entre los años 2004 a 2017. Resultados. Se encontraron 84 pacientes que fueron trasplantados con esas características. La edad promedio de los pacientes fue de 59±10,5 con una mayor proporción significativa de hombres sobre mujeres, llegando casi al 70 %. Con relación a las comorbilidades, se encontró que el sobrepeso/obesidad, la hipertensión arterial y la diabetes mellitus tipo 2 fueron un hallazgo en el 44,1 %, 33,3 % y 33,3 %, respectivamente. Por otro lado, el 14,5 %, el 33,7 % y el 51,8 % presentaron un Child-Pugh A, B y C, respectivamente. La media del puntaje MELD fue de 18,9±6,26. Con respecto a las complicaciones de la cirrosis, el 77,4 % de los pacientes presentó ascitis, el 61,9 % encefalopatía hepática, el 36,9 % hemorragia del tracto digestivo superior y el 29,8 % peritonitis bacteriana espontánea. Conclusión. Los resultados expuestos mostraron nuestra experiencia en trasplante hepático en pacientes con CH y CHC asociado a MASLD. Se debe realizar una evaluación multidisciplinaria antes y después del trasplante en estos pacientes, haciendo especial énfasis en el manejo de la disfunción metabólica y sus componentes, entre los que se destacan la obesidad y la diabetes mellitus.


Introduction. Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most frequent chronic liver disease in Western countries, causing increased costs and hospital occupancy. The comprehensive pre-transplant characterization in patients with MASLD is a major question, especially in our setting. The aim of the present study was to perform the clinical-epidemiological characterization of transplanted patients with decompensated liver cirrhosis (LC) or hepatocellular carcinoma (HCC) associated with MASLD. Methodology. A retrospective, descriptive, cross-sectional observational study was carried out in the Hepatology Department of the Pablo Tobón Uribe Hospital in Medellin, Colombia. Patients over 17 years of age, with a diagnosis of LC or HCC associated with MASLD who were transplanted between 2004 and 2017 were included. Results. We found 84 patients who were transplanted with these characteristics. The mean age of the patients was 59±10.5 with a significantly higher proportion of men over women, reaching almost 70%. Regarding comorbidities, overweight/obesity, arterial hypertension, and type 2 diabetes mellitus were found in 44.1%, 33.3%, and 33.3%, respectively. On the other hand, 14.5%, 33.7%, and 51.8% had Child-Pugh A, B, and C, respectively. The mean MELD score was 18.9±6.26. Regarding complications of cirrhosis, 77.4% of patients developed ascites, 61.9% hepatic encephalopathy, 36.9% upper gastrointestinal tract hemorrhage, and 29.8% spontaneous bacterial peritonitis. Conclusion. The above results showed our experience of liver transplantation in patients with LC and HCC associated with MASLD. A multidisciplinary evaluation should be performed before and after transplantation in these patients, with special emphasis on the management of metabolic dysfunction and its components, including obesity and diabetes mellitus.

RESUMO

Objetivo: Estudiar el estado de salud de un grupo de pacientes con trasplante hepático (TH) por enfermedad relacionada con el consumo de alcohol vs. otras etiologías, antes y después del trasplante. Método: Estudio longitudinal de cohortes en pacientes trasplantados hepáticos desde noviembre de 2019 hasta julio de 2022. Se incluyeron pacientes atendidos para un primer TH tanto electivo como urgente en la Unidad de Trasplantes de un hospital. Se excluyeron aquellos pacientes que ya portaban un órgano trasplantado y aquellos que necesitaron un re-TH en el primer mes tras el primer trasplante. Se recogieron variables sociodemográficas y clínicas, Model for End-Stage Liver Disease (MELDNa), índice de fragilidad hepática (LFI), efectos emocionales-conductuales del trasplante, nivel de ansiedad y depresión. En el análisis estadístico se utilizaron las pruebas de X2 de Pearson, t de Student, U de Mann-Whitney y el signo de Wilcoxon. Resultados: La muestra fue n = 67 pacientes trasplantados hepáticos, con una edad promedio de 56,37 años, siendo 67,2% hombres y 39% por enfermedad hepática relacionada con el alcohol (EHRA). De todos los pacientes incluidos, 9% fueron trasplantes urgentes. El consumo de alcohol se asoció con una mayor edad, una alta tasa de fragilidad hepática y una situación laboral no activa. La etiología alcohólica se correlacionó con una mayor preocupación durante los primeros seis meses después del trasplante de hígado. Conclusión: Existen diferencias en el estado de salud de los pacientes trasplantados hepáticos por EHRA vs. otra etiología. Las enfermeras deben considerar la etiología de la enfermedad hepática para orientar los cuidados y las intervenciones durante todo el proceso de trasplante.(AU)


Aim: To study the health status of a group of patients with liver transplantation by alcohol-related disease vs another etiology before and after the transplantation. Method: Longitudinal cohort study of liver transplant patients from November 2019 to July 2022. Adult patients attended in the unit of transplantation of a hospital for a first liver transplant, both elective and urgent, were included. Patients who already had a transplanted organ and those who required liver re-transplantation in the first month after the first transplant were excluded. Sociodemographic and clinical variables, MELDNa, liver frailty index, emotional-behavioral effects of transplantation, level of anxiety and depression were collected. Pearson's chi-square, Student's t, Mann-Whitney U, and Wilcoxon sign tests were used for statistical analysis. Results: The sample was n = 67 liver transplant patients with a mean age of 56.37 years, 67.2% being men and 39% due to alcohol-related liver disease. 9% of all included patients were urgent transplants. Alcohol consumption was associated with older age, a high rate of liver frailty, and a non-active work situation. Alcoholic etiology correlated with increased concern during the first six months after liver transplantation. Conclusion: There are differences in the health status between liver transplant patients for alcohol-related liver disease vs other etiology. Nurses must consider the etiology of liver disease to guide care and interventions throughout the transplant process.(AU)

RESUMO

Introducción. El acceso al trasplante hepático (TH) en pacientes con carcinoma hepatocelular (CHC) se basa en la aplicación de criterios morfológicos rigurosos estipulados desde 1996, co-nocidos como criterios de Milán. Una de las estrategias descritas para expandir estos criterios se conoce como downstaging (reducción del estadiaje tumoral mediante terapias locorregionales). El objetivo de este estudio fue describir el comportamiento postrasplante de pacientes con CHC que ingresaron dentro de los parámetros de Milán, comparado con el de aquellos pacientes llevados a terapia de downstaging en un centro colombiano. Metodología. Se incluyeron pacientes adultos con cirrosis hepática (CH) y CHC que fueron llevados a TH en el Hospital Pablo Tobón Uribe, entre julio de 2012 a septiembre de 2021. Como desenlace principal se definió recurrencia y tiempo de recurrencia de la enfermedad tumoral, muerte por todas las causas y tiempo al fallecimiento. Se evaluaron las características sociodemográficas y clínicas de cada grupo. Se incluyeron scores pronósticos de recurrencia de la enfermedad tumoral. Resultados. Se trasplantaron 68 pacientes con CH y CHC, 50 (73,5 %) eran hombres y la edad promedio fue 59 años; 51 pacientes (75 %) cumplían con los criterios de Milán y 17 (25 %) fueron llevados a terapia de downstaging previo al TH. No hubo diferencias significativas en la supervivencia global y supervivencia libre de trasplante entre los dos grupos evaluados, p=0,479 y p=0,385, respectivamente. Tampoco hubo diferencia significativa en la recurrencia de la enfermedad tumoral entre ambos grupos (p=0,81). En total hubo 7 casos de recurrencia tumoral (10,2 %) y 11 casos de muerte (16,2 %). Conclusiones. No se encontraron diferencias significativas en recurrencia y mortalidad entre los pacientes que cumplían los criterios de Milán y los trasplantados luego de la terapia de downstaging, en un tiempo de se-guimiento de 53 meses hasta el último control posterior al trasplante hepático. Esta sería la primera evaluación prospectiva de un protocolo de downstaging para CHC en Colombia.


Introduction. Access to liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) is based on the application of rigorous morphological criteria stipulated since 1996, known as the Milan criteria. One of the strategies described to expand these criteria is known as downstaging (tu-mor staging reduction through locoregional therapies). The objective of this study was to describe the post-transplant performance of patients with HCC who were admitted within the Milan parameters, compared with those of patients taken to downstaging therapy, in a Colombian center. Methodolo-gy. Adult patients with cirrhosis and HCC that received LT between July 2012 and September 2021 at the Pablo Tobón Uribe Hospital were included. The main outcome was defined as recurrence and time to recurrence of the tumor disease, death from all causes, and time to death. The socio-demographic and clinical characteristics of each group were evaluated. Tumor disease recurrence prognostic scores were included. Results. Sixty-eight patients with cirrhosis and HCC received LT in the time frame, 50 (73.5%) were men and the mean age was 59 years. Fifty-one patients were trans-planted (75%) fulfilling Milan criteria, and 17 (25%) patients received downstaging therapies before LT. There were no significant differences in overall survival and transplant-free survival between the two groups, p=0.479 and p=0.385, respectively. There was also no significant difference in the recurrence of the tumor disease between both groups (p=0.81). In total there were 7 tumoral recurrences (10.2%) and 11 deaths (16.2%). Conclusions. There were no differences in recurrence and survival between patients transplanted fulfilling Milan criteria and those receiving downstaging therapies, following a mean time of 53 months after LT. This is the first prospective evaluation of the downstaging protocol in Colombia.

RESUMO

Resumo Objetivo Avaliar o conhecimento de pacientes e profissionais de saúde sobre os protocolos de vacinação no pós-transplante hepático antes e após a aplicação de uma estratégia educativa de conscientização nessa população. Métodos Os pacientes (n=124) foram submetidos à intervenção educativa através do acesso a uma página web com vídeos educativos e, para os profissionais de saúde (n=111), através de um simpósio e acesso à informação na página virtual do projeto. Para analisar o efeito da intervenção, análises qualitativas de conhecimento foram realizadas por meio de questionários antes e depois das intervenções. Resultados Entre os pacientes, predominou o sexo masculino (66,9%) e a média de idade foi de 55,2 anos (DP + 15,9). 82,2% dos pacientes procuraram uma UBS para serem vacinados e 13,7% deles, os CRIEs (Centro de Referência para Imunobiológicos Especiais). Apenas 46,7% receberam orientações sobre vacinas após o transplante hepático. Dos 111 questionários respondidos pelos profissionais de saúde, 46,5% não consultaram a carteira de vacinas, 61,3% encaminharam os pacientes para UBS e 38,7%, para um CRIE. Na análise pós-intervenção, 66,1% dos pacientes assistiram a vídeos educativos sobre vacinação. Destes, 62,2% disseram ter melhorado seu entendimento sobre as vacinas e 91,4% se sentem mais seguros para vacinar. Após a intervenção educativa, 45 profissionais de saúde responderam ao questionário. 30,4% afirmaram saber quais vacinas prescrever e 67,4% indicaram vacinas para familiares de pacientes. Conclusão A estratégia educacional proposta aplicada neste estudo mostrou aumentar a conscientização sobre os protocolos de imunização pós-transplante hepático. Isso pode contribuir para evitar o risco potencial de falta de informação e não abordagem da vacinação pelos profissionais de saúde.

Métodos Los pacientes (n=124) fueron sometidos a la intervención educativa mediante el acceso a un sitio web con videos educativos, y los profesionales de la salud (n=11), mediante un simposio y el acceso a información en la página web del proyecto. Para analizar el efecto de la intervención, se realizaron análisis cualitativos de conocimiento con cuestionaros antes y después de la intervención. Resultados Entre los pacientes, el sexo masculino fue predominante (66,9 %) y la edad promedio fue 52,2 años (SD + 15,9). El 82,2 % de los pacientes fue a una Unidad Básica de Salud (UBS) para recibir la vacuna y el 13,7 % de ellos acudió a un Centro de Referencia para Inmunobiológicos Especiales (CRIE). Solo el 46,7 % recibió instrucciones sobre vacunación tras el trasplante hepático. De los 111 cuestionarios respondidos por profesionales de la salud, el 46,5 % no consultó el catálogo de vacunas, el 61,3 % derivó a los pacientes a una UBS y el 38,7 % a un CRIE. En el análisis posintervención, el 66,1 % de los pacientes miró los videos educativos sobre vacunación. De ellos, el 62,2 % mencionó haber mejorado su comprensión sobre vacunas y el 91,4 % se sintió más seguro para vacunarse. Después de la intervención educativa, 45 profesionales de la salud respondieron el cuestionario. El 30,4 % afirmó saber qué vacunas prescribir y el 67,4 % recomendó vacunas a familiares de los pacientes. Conclusión La estrategia educativa propuesta aplicada en este estudio demostró un aumento de conocimiento sobre los protocolos de inmunización tras un trasplante hepático. Esto pude ayudar a evitar el riesgo potencial de la falta de información y el no abordar el tema de la vacunación por parte de los profesionales de la salud.


Abstract Objective To evaluate patients' and healthcare professionals' knowledge about vaccination protocols in post-liver transplantation before and after applying an educational awareness strategy in this population. Methods Patients (n=124) underwent the educational intervention through access to a webpage containing educational videos and, for health professionals (n=111), through a symposium and access to information on the project's virtual page. To analyze the effect of the intervention, qualitative analyses of knowledge were carried out using questionnaires before and after the interventions. Results Among patients, males were predominant (66.9%) and the mean age was 55.2 years old (SD + 15.9). 82.2% of patients visited a UBS to be vaccinated and 13.7% of them the CRIEs (Reference Center for Special Immunobiologicals). Only 46.7% received orientation about vaccines after liver transplantation. From the 111 questionnaires answered by health professionals, 46.5% did not check the vaccine portfolio, 61.3% referred patients to UBS and 38.7% to a CRIE. In the post-intervention analysis, 66.1% of patients watched educational videos about vaccination. Of these, 62.2% said they had improved their understanding about vaccines and 91.4% feel safer to vaccinate. After the educational intervention, 45 health professionals answered the questionnaire. 30.4% said they knew which vaccines to prescribe, and 67.4% recommended vaccines to patients' relatives. Conclusion The proposed educational strategy applied in this study shown to increase awareness regarding the post-liver transplant immunization protocols. This may contribute to avoiding the potential risk of lack of information and failure to address vaccination by healthcare professionals.

RESUMO

Introducción. La enfermedad hepática inducida por uso de alcohol se ha considerado una enferme-dad autoinfligida que limitaba el acceso al trasplante. Actualmente es una de las principales indicacio-nes de trasplante hepático en Colombia y el mundo, con excelente sobrevida. Metodología. Estudio descriptivo observacional donde se realizó una caracterización de los pacientes con trasplante hepá-tico por hepatopatía alcohólica en una institución de cuarto nivel, que incluyó un estudio cualitativo de la recaída en el consumo de alcohol postrasplante. Resultados. De 87 pacientes de una cohorte inicial de 96 pacientes trasplantados entre 2003 y 2021, se describieron características sociodemo-gráficas, comorbilidades previas y adquiridas posterior al trasplante, supervivencia del paciente y del injerto, y factores de riesgo asociados al consumo de alcohol. Adicionalmente, a 65 pacientes se les pudo realizar una entrevista estructurada para evaluar la recaída en el consumo de alcohol, 41,53 % volvieron a consumir alcohol; 23,07 % en patrón de riesgo de recaída y 18,46 % en patrón de slip (desliz). El antecedente de hepatitis alcohólica tuvo un RR de 3,273 (1,464­7,314) y p=0,007 para recaída en el consumo de alcohol, y la comorbilidad psiquiátrica un RR de 2,395 (1,002­5,722) y p=0,047. Finalmente, haber presentado al menos una recaída postrasplante tuvo un RR de 5,556 (1,499­20,588) con p=0,005 para rechazo del injerto. Conclusiones. La recaída en el consumo de alcohol fue frecuente, la hepatitis alcohólica previa y la comorbilidad psiquiátrica son factores de riesgo asociados. La recaída se asoció a rechazo del injerto sin afectar la sobrevida del paciente.


Introduction. Alcohol-induced liver disease has been considered a self-inflicted disease that limited access to transplantation. It is currently one of the main indications for liver transplantation in Colom-bia and the world, with excellent survival. Methodology. Observational descriptive study where a characterization of liver transplant patients due to alcoholic liver disease was carried out in a fourth level institution, which included a qualitative study of relapse in post-transplant alcohol consumption. Results. Of 87 patients from an initial cohort of 96 transplant patients between 2003 and 2021, sociodemographic characteristics, previous and acquired post-transplant comorbidities, patient and graft survival, and risk factors associated with alcohol consumption were described. Additionally, 65 patients were able to undergo a structured interview to assess relapse in alcohol consumption, 41.53% returned to alcohol consumption; 23.07% in risk relapse pattern, and 18.46% in slip pattern. The history of alcoholic hepatitis had a RR of 3.273 (1.464-7.314) and a p=0.007 for relapse in alcohol consumption, and psychiatric comorbidity a RR of 2.395 (1.002-5.722) and a p=0.047. Finally, having presented at least one post-transplant relapse had a RR of 5.556 (1.499-20.588) with ap=0.005 for graft rejection. Conclusions. Relapse in alcohol consumption was fre-quent, previous alcoholic hepatitis and psychiatric comorbidity were associated risk factors. Relapse was associated with graft rejection without affecting patient survival.

RESUMO

BACKGROUND: Infections related to non-surgical manipulation of the biliary tract (NSMBT) are common events despite periprocedural antibiotic prophylaxis (PAP). Since June 2017, our local protocol has indicated a 24-h regimen of intravenous piperacillin-tazobactam for this purpose. OBJECTIVE: We aimed to describe the incidence and characteristics of NSMBT-related paediatric infections, define risk factors for their development, and analyse adherence to our PAP protocol. MATERIALS AND METHODS: Epidemiological, clinical, and microbiological data were collected in consecutive NSMBT procedures performed in paediatric patients (<18 years) in our centre (2010-2019). RESULTS: 113 procedures in 37 patients, median age 4 years (IQR 1-8), were included. Main underlying diseases were biliary atresia (32%) and cancer (14%). Sixty-eight percent had undergone liver transplant and 70% hepaticojejunostomy. In 44 procedures (39%), the intervention was performed during the course of infection and previously prescribed antibiotic treatment was maintained. In the other 69, PAP was specifically indicated for NSMBT; antibiotic adequacy increased from 35% to 100% after June 2017. In total, 32 NSMBT-related infections (28%) occurred, mainly in the first 24h post-procedure (72%); no deaths happened. Causative pathogens were Gram-negative rods (64%), Gram-positive cocci (28%), and Candida spp. (8%). Main related risk factors were hepaticojejunostomy, biliary obstruction, and liver transplant. CONCLUSIONS: NSMBT in children entails a significant infection risk, even under antibiotic prophylaxis, being hepaticojejunostomy the main risk factor. Infectious complications mainly occurred immediately after the procedure. After establishing a PAP protocol, 100% of interventions received appropriate prophylaxis, decreasing antibiotic exposure time and potentially, the length of hospital stay.

RESUMO

Resumen Introducción: la valoración hemodinámica mediante ecocardiografía Doppler tiene importancia en la identificación de alteraciones sistólicas/diastólicas como predictor de desenlaces en el postrasplante hepático desde alteraciones cardiovasculares hasta disfunción del injerto y mortalidad. Métodos: estudio de cohorte retrospectivo. Paciente con trasplante hepático en el hospital LaCardio, en Bogotá, Colombia entre enero de 2005 y julio de 2021. Análisis de variables sociodemográficas, comorbilidades, ecocardiografía y variables intraoperatorias con desenlaces primarios como disfunción temprana del injerto, lesión renal aguda (LRA) y mortalidad durante el seguimiento. Se realizó un árbol de clasificación y regresión (CART). Resultados: se analizaron a 397 pacientes, el 54,4% eran hombres, y el 71% tenía algún grado de disfunción diastólica, hipertrofia ventricular izquierda (30,9%) con presencia de disfunción del injerto en el 8% y LRA en el 21%, y una mortalidad del 15% durante el seguimiento del estudio. En el modelo CART para desenlaces de mortalidad y disfunción del injerto se relacionó con la presencia de índice de masa corporal (IMC) < 19 o la combinación de IMC entre 19 y < 24 con diálisis. Conclusión: las variables ecocardiográficas, la sarcopenia y la LRA o requerimiento de terapia de reemplazo renal se relacionan con desenlaces de mortalidad y disfunción del injerto.


Abstract Introduction: Hemodynamic assessment by Doppler echocardiography is essential in identifying systolic/diastolic changes as a predictor of outcomes in post-liver transplantation, from cardiovascular changes to graft dysfunction and mortality. Materials and methods: Retrospective cohort study. Patient with a liver transplant at the LaCardio hospital in Bogotá, Colombia, between January 2005 and July 2021. Analysis of sociodemographic variables, comorbidities, echocardiography, and intraoperative variables with primary outcomes such as early graft dysfunction, acute kidney injury (AKI), and mortality during follow-up. A classification and regression tree (CART) was performed. Results: 397 patients were analyzed; 54.4% were men, 71% had some degree of diastolic dysfunction and left ventricular hypertrophy (30.9%) with graft dysfunction in 8% and AKI in 21%, and a mortality of 15% during the study follow-up. In the CART model, mortality and graft dysfunction outcomes were related to a body mass index (BMI) < 19 or a combination of BMI between 19 and < 24 with dialysis. Conclusion: Echocardiographic variables, sarcopenia, AKI, or the requirement for renal replacement therapy are related to mortality and graft dysfunction outcomes.

RESUMO

Resumen El síndrome del linfocito pasajero (PLS) es una complicación de injerto contra huésped que se presenta en el trasplante de órganos sólidos o en el trasplante de células progenitoras hematopoyéticas. Es una causa importante de hemólisis inmune después del trasplante causada por la producción de anticuerpos por parte de los clones específicos de linfocitos B viables transferidos a través del órgano del donante contra los antígenos de los glóbulos rojos del receptor. Generalmente ocurre en los trasplantes con discordancia menor ABO o Rh. Este estudio descriptivo describe el caso de un paciente de 54 años con grupo sanguíneo O/Rh(D) positivo, con cirrosis secundaria a enfermedad metabólica asociada al hígado graso (MAFLD) que fue llevado a trasplante hepático de donante O/Rh(D) negativo. A los 9 días del trasplante presentó una anemia hemolítica inmune por anticuerpos anti-D por efecto del linfocito B pasajero del donante sensibilizado. El paciente recibió medidas de soporte, transfusión de glóbulos rojos e inmunosupresión con esteroides, con lo que se logró la estabilización de los parámetros hemolíticos. En conclusión, esta es una entidad que se debe sospechar en caso de anemia hemolítica aguda en el período postrasplante.


Abstract Passenger lymphocyte syndrome (PLS) is a graft-versus-host complication in solid organ transplantation or hematopoietic stem cell transplantation. It is a major cause of immune hemolysis after transplantation caused by the production of antibodies by the specific clones of viable B lymphocytes transferred through the donor organ against the antigens of the recipient's red blood cells. It usually occurs in transplants with minor ABO or Rh mismatch. This descriptive study explains the case of a 54-year-old patient with O/Rh(D) positive blood group, with cirrhosis secondary to metabolic disease associated with fatty liver (NAFLD), who underwent liver transplantation from an O/Rh(D) negative donor. Nine days after the transplant, the patient presented with immune hemolytic anemia due to anti-D antibodies because of the transient B lymphocyte from the sensitized donor. The patient received support measures, transfusion of red blood cells, and immunosuppression with steroids, which stabilized the hemolytic parameters. In conclusion, this entity should be suspected in the case of acute hemolytic anemia in the post-transplant period.

RESUMO

Resumen Objetivo: describir un caso de trasplante hepático en un paciente con resultado positivo en la prueba del coronavirus del síndrome respiratorio agudo grave de tipo 2 (SARS-CoV-2) con éxito en el postrasplante temprano, pero que desarrolló complicaciones asociadas a la inmunosupresión y trombosis portal sin una trombofilia identificada en un centro de alta complejidad de un país latinoamericano. Descripción del caso: paciente de 48 años con diagnóstico de cirrosis hepática secundaria a esteatohepatitis no alcohólica (NASH) complicada por varios episodios de ascitis portal hipertensiva y encefalopatía hepática, ingresada para trasplante hepático ortóptico. En los exámenes iniciales tuvo una prueba positiva para SARS-CoV-2 y era asintomático respiratorio. El trasplante se realizó con éxito luego de la autorización del comité de infección. Después del primer mes posoperatorio presentó diarrea, ascitis y daño renal agudo. Los niveles de tacrolimus en el reingreso fueron superiores a 10 ng/mL y hubo una mejoría clínica significativa con la suspensión del fármaco. Finalmente, el paciente requirió retrasplante por trombosis de la vena porta y de las venas suprahepáticas, aunque no se identificó la etiología. Conclusión: se describe uno de los primeros informes de trasplante de hígado en un paciente con recuperación reciente de COVID-19 y pruebas persistentemente positivas. En el postrasplante temprano hubo una buena respuesta; sin embargo, luego del primer mes presentó complicaciones relacionadas con la inmunosupresión. Este caso también plantea la posible asociación entre el SARS-CoV-2 y el desarrollo de trombosis en la circulación portal hepática.


Abstract Objective: To describe a case of liver transplantation in a patient with a positive result in the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) test with success in the early post-transplantation, but who developed complications associated with immunosuppression and portal vein thrombosis without thrombophilia identified at a tertiary referral center in a Latin American country. Case: A 48-year-old patient diagnosed with liver cirrhosis secondary to non-alcoholic steatohepatitis (NASH) complicated by several episodes of portal hypertension ascites and hepatic encephalopathy was admitted for orthoptic liver transplantation. On initial examinations, he had a positive test for SARS-CoV-2 and was asymptomatic in the respiratory tract. The transplant was carried out successfully after the authorization of the infection committee. After the first postoperative month, he presented with diarrhea, ascites, and acute kidney injury. Tacrolimus levels at readmission were more significant than 10 ng/mL, and there was a significant clinical improvement with drug discontinuation. Finally, the patient required re-transplantation due to thrombosis of the portal vein and suprahepatic veins, although the etiology was not identified. Conclusion: One of the first reports of liver transplantation in a patient with recent recovery from COVID-19 and persistently positive tests is described. In the early post-transplant, there was a good response; however, after the first month, he had complications related to immunosuppression. This case also posits the possible association between SARS-CoV-2 and the development of thrombosis in the hepatic portal circulation.

RESUMO

As doenças hepáticas crônicas trazem alterações metabólicas no organismo que alteram a qualidade de vida do indivíduo. A depender da gravidade clínica, o transplante hepático surge como uma proposta terapêutica que necessita de inclusão no Sistema Nacional de Transplantes e avaliação multiprofissional. O objetivo deste trabalho é identificar as expectativas que os pacientes candidatos ao transplante hepático expressam sobre esta terapêutica. Trata-se de um estudo descritivo, de abordagem qualitativa, que utilizou o método da pesquisa documental nos Formulários de Avaliação Psicológica Pré Transplante do serviço de psicologia de um hospital universitário em Fortaleza, Ceará. Foram analisados 202 Formulários pelo método de análise de conteúdo de Bardin que se dividiram em três categorias: 1. Diminuição dos sintomas a recuperação à saúde; 2. Esperança frente ao desconhecido; 3. Reconstrução da identidade. A pesquisa permitiu identificar as principais expectativas dos pacientes relacionados ao transplante hepático, delineando os aspectos que são sustentadores para que os sujeitos deem continuidade ao tratamento, a saber: rede social de apoio, possibilidade de melhora clínica e aumento da sobrevida, sentimentos de esperança e desejo de qualidade de vida. O desejo de cura está relacionado à recuperação da cirurgia e não apenas ao desaparecimento da doença hepática. (AU)


Chronic liver diseases bring metabolic changes in the body that affect the individual's quality of life. Depending on the clinical severity, liver transplantation emerges as a therapeutic proposal that requires inclusion in the National Transplant System and multidisciplinary evaluation. The aim of this study was to identify the expectations that patients who are candidates for liver transplantation express about this therapy. This is a descriptive, qualitative study that used the documentary research method in the Pre-Transplant Psychological Assessment Forms of the psychology service at a university hospital in the city of Fortaleza, Ceará. 202 Forms were analyzed using Bardin's content analysis method, which were divided into three categories: 1. Reduction of symptoms and recovery to health; 2. Hope in the face of the unknown; 3. Reconstruction of identity. The research identified the main expectations of patients related to liver transplantation, outlining the aspects that support subjects in continuing treatment, namely: social support network, the possibility of clinical improvement and increased survival, feelings of hope, and desire for quality of life. The desire for a cure is related to recovery from surgery and not just to the disappearance of liver disease. (AU)

RESUMO

Background: Infections related to non-surgical manipulation of the biliary tract (NSMBT) are common events despite periprocedural antibiotic prophylaxis (PAP). Since June 2017, our local protocol has indicated a 24-h regimen of intravenous piperacillin–tazobactam for this purpose. Objective: We aimed to describe the incidence and characteristics of NSMBT-related paediatric infections, define risk factors for their development, and analyse adherence to our PAP protocol. Materials and methods: Epidemiological, clinical, and microbiological data were collected in consecutive NSMBT procedures performed in paediatric patients (<18 years) in our centre (2010–2019). Results: 113 procedures in 37 patients, median age 4 years (IQR 1–8), were included. Main underlying diseases were biliary atresia (32%) and cancer (14%). Sixty-eight percent had undergone liver transplant and 70% hepaticojejunostomy. In 44 procedures (39%), the intervention was performed during the course of infection and previously prescribed antibiotic treatment was maintained. In the other 69, PAP was specifically indicated for NSMBT; antibiotic adequacy increased from 35% to 100% after June 2017. In total, 32 NSMBT-related infections (28%) occurred, mainly in the first 24h post-procedure (72%); no deaths happened. Causative pathogens were Gram-negative rods (64%), Gram-positive cocci (28%), and Candida spp. (8%). Main related risk factors were hepaticojejunostomy, biliary obstruction, and liver transplant. Conclusions: NSMBT in children entails a significant infection risk, even under antibiotic prophylaxis, being hepaticojejunostomy the main risk factor. Infectious complications mainly occurred immediately after the procedure. After establishing a PAP protocol, 100% of interventions received appropriate prophylaxis, decreasing antibiotic exposure time and potentially, the length of hospital stay.(AU)


Antecedentes: Las infecciones relacionadas con la manipulación no quirúrgica de las vías biliares (MNQVB) son acontecimientos frecuentes, a pesar de la profilaxis antibiótica periprocedimiento (PAP). Desde junio de 2017, nuestro protocolo local indica una pauta de 24 h de piperacilina/tazobactam por vía intravenosa para este fin. Objetivo: El objetivo era describir la incidencia y las características de las infecciones pediátricas relacionadas con la MNQVB, definir los factores de riesgo para su desarrollo y analizar el cumplimiento de nuestro protocolo de PAP. Materiales y métodos: Se recogieron datos epidemiológicos, clínicos y microbiológicos en procedimientos consecutivos de MNQVB realizados en pacientes pediátricos (< 18 años) en nuestro centro (2010-2019). Resultados: Se incluyeron 113 procedimientos en 37 pacientes, con una mediana de edad de 4 años (RIC 1-8). Las principales enfermedades subyacentes fueron atresia biliar (32%) y cáncer (14%). El 68% se había sometido a un trasplante de hígado y el 70% a una hepaticoyeyunostomía. En 44 procedimientos (39%), la intervención se realizó durante el transcurso de la infección y se mantuvo el tratamiento antibiótico recetado previamente. En los otros 69, la PAP estaba indicada específicamente para la MNQVB; la eficacia de los antibióticos aumentó del 35 al 100% después de junio de 2017. En total, se produjeron 32 infecciones relacionadas con la MNQVB (28%), principalmente en las primeras 24 h posteriores al procedimiento (72%); no se produjo ninguna muerte. Los patógenos causantes fueron bacilos gramnegativos (64%), cocos grampositivos (28%) y Candida spp. (8%). Los principales factores de riesgo relacionados fueron la hepaticoyeyunostomía, la obstrucción biliar y el trasplante de hígado.(AU)

RESUMO

Gracias a los grandes avances de la tecnología, los últimos diez años, la impresión en tres dimensiones (3D) se ha convertido en una herramienta accesible, útil e innovadora para distintas áreas de la medicina. Entre ellas planificación quirúrgica, creación de implantes y prótesis, educación médica e incluso comunicación médico-paciente. Con respecto a planificación quirúrgica, la impresión 3D cobra especial relevancia en cirugías de alta complejidad. En el caso del trasplante hepático con donante vivo, donde es prioritario garantizar la máxima seguridad para el donante, al mismo tiempo que la mejor calidad del injerto para el receptor, la planificación quirúrgica es mandatoria. En este aspecto, la impresión 3D de un modelo de hígado, anatómicamente comparable al del donante, entrega al cirujano la posibilidad de obtener una imagen más clara, directa y tangible, desde cualquier ángulo del órgano, que una imagen virtual tradicional. De esta forma, el cirujano tiene a su alcance una herramienta adicional para plantear el mejor abordaje quirúrgico, anticipar variaciones anatómicas e incluso, cuando el material de impresión lo permite, practicar el procedimiento. En Clínica Las Condes, el centro de trasplante junto al Centro de Innovación, trabajaron en conjunto en la impresión 3D de dos modelos de hígado, utilizados para la planificación quirúrgica de los primeros dos trasplantes hepáticos con donante vivo adulto-adulto realizados en Latinoamérica, donde la hepatectomía del donante se realizó de manera totalmente laparoscópica. El objetivo de este trabajo es describir el proceso de impresión 3D y analizar las dificultades y beneficios del proceso y sus resultados.


The last ten years, thanks to the great advances in technology, three-dimensional (3D) printing has become an accessible, useful, and innovative tool for different areas of medicine. These include surgical planning, implant and prosthetic creation, medical education, and even doctor-patient communication. Regarding surgical planning, 3D printing takes on special relevance in highly complex surgeries. In the case of living donor liver transplantation where it is a priority to guarantee maximum safety for the donor, as well as the best quality of the graft for the recipient, surgical planning is mandatory. Regarding this, 3D printing of an anatomically comparable liver model of the donor, gives the surgeon the possibility of obtaining a clearer, more direct, and tangible image, from any angle of the organ, than a traditional virtual image. In this manner, the surgeon has an additional tool to plan the best surgical approach, anticipate anatomical variations and even, when the impression material allows it, to practice the procedure. Transplant center of Clinica las Condes, together with Innovation laboratory worked together on the 3D printing process liver models used for surgical planning of the first two liver transplants with an adult-adult laparoscopic living donor. The objective of this work is to describe the 3D printing process and analyze the difficulties and benefits of the process and its results.

RESUMO

La hipertensión portopulmonar (HTPP) es una complicación infrecuente de la hipertensión portal, que sigue un curso progresivo con un pronóstico sombrío. Los reportes en pacientes pediátricos son escasos y con períodos de seguimiento cortos. Se describe una paciente con cirrosis descompensada que desarrolló HTPP resuelta mediante trasplante hepático, que permanece asintomática tras diez años de seguimiento.


Portopulmonary hypertension is an uncommon complication of portal hypertension, running a progressive course with a negative prognosis. Reports in pediatric patients are scarce with short follow up. We describe the case of decompensated cirrhosis who developed PoPH and resolved with liver transplantation, remaining asymptomatic after ten years of follow up.

RESUMO

Background and aims: Inflammatory bowel diseases (IBD) are chronic conditions that may be accompanied by autoimmune liver disease (AILD), most commonly primary sclerosing cholangitis (PSC). The objective of this study was to evaluate the behaviour of patients with IBD associated with AILD and compare a PSC group with a non-PSC group.Methods: Medical records of patients with IBD associated with PSC, autoimmune cholangitis, primary biliary cholangitis, small-duct PSC, autoimmune hepatitis (AIH) and overlapping syndromes were assessed.Results: Fifty-four patients were included: 48 (88.9%) had ulcerative colitis and six (11.1%) had Crohn's disease; 35 (64.8%) had PSC and 19 (35.2%) did not have PSC. There was no difference in outcomes (surgical treatment for IBD, liver transplantation or death) between the groups. Time since the diagnosis of IBD was associated with surgical treatment of IBD (p=0.041; OR: 1.139, 95% CI: 1.006–1.255). Time since the diagnosis of AILD (p=0.003; OR: 1.259, 95% CI: 1.1–1.396), as well as portal hypertension at diagnosis (p=0.014; OR: 18.22, 95% CI: 1.815–182.96), were associated with liver transplantation. In addition, previous diagnosis of AIH was associated with de novo IBD (p=0.012; OR: 7.1, 95% CI: 1.215–42.43).Conclusion: Both groups had similar disease behaviour. A longer time since the diagnosis of IBD increased the risk for surgical treatment (13.9%/year). A 25.9%/year increase in liver transplantation was observed after the diagnosis of AILD, which was increased 18.22 times by the presence of portal hypertension. In addition, the diagnosis of AIH was associated with an increase in the number of diagnoses of de novo IBD (7.1).


Antecedentes y objetivos: Las enfermedades inflamatorias intestinales (EII) son afecciones crónicas que pueden ir acompañadas de enfermedad hepática autoinmune (EHA) o colangitis esclerosante primaria (CEP). El objetivo del estudio fue evaluar el comportamiento de pacientes con EII asociada a EHA y comparar un grupo con CEP con un grupo sin CEP.Métodos: Se evaluaron las historias clínicas de pacientes con EII asociadas con CEP, colangitis autoinmune, colangitis biliar primaria, CEP de conductos pequeños, hepatitis autoinmune (HAI) y síndromes superpuestos.Resultados: Se incluyeron 54 pacientes. De ellos, 48 (88,9%) tenían colitis ulcerosa y seis (11,1%) tenían enfermedad de Crohn; 35 (64,8%) tenían CEP y 19 (35,2%) no tenían CEP. No hubo diferencias en los resultados (tratamiento quirúrgico para la EII, trasplante de hígado o muerte) entre los grupos. El tiempo transcurrido desde el diagnóstico de EII se asoció con el tratamiento quirúrgico de la EII (p=0,041). El tiempo desde el diagnóstico de EHA (p=0,003), así como la hipertensión portal en el momento del diagnóstico (p=0,014), fueron asociado con el trasplante de hígado. Además, el diagnóstico previo de HAI se asoció con EII de novo (p=0,012).Conclusión: Ambos grupos tuvieron un comportamiento de enfermedad similar. Un mayor tiempo desde el diagnóstico de EII aumentó el riesgo de tratamiento quirúrgico (13,9%/año). Se observó un aumento del 25,9%/año en el trasplante de hígado después de diagnóstico de EIA, que se incrementó 18,22 veces por la presencia de hipertensión portal. Además, el diagnóstico de HAI se asoció con un aumento en el número de diagnósticos de EII de novo (7,1).

RESUMO

Background: Acute hepatitis A is usually a self-limited viral disease but can be severe and even fatal in special groups of patients including those with chronic liver disease and recipients of liver transplantation. To take appropriate preventive measures, it is important to determine the immune status against the hepatitis A virus in patients at risk of grave clinical outcomes following infection. To assess the need for immunization against hepatitis A, we aimed to determine the immune status against hepatitis A in a population of liver transplant recipients. We also investigated the association between hepatitis A immune status and demographic factors such as age and sex, underlying liver disease, source of drinking water, geographical area of residence and socioeconomic status.Methods: This cross-sectional study was performed on 242 recipients of allogenic liver transplants at Abu Ali Sina Organ Transplant Hospital in Shiraz, Iran, between January 2017 and April 2017. The level of immunity was assessed using hepatitis A antibody detection kits.Results: The rate of immunity against hepatitis A was detected as 88.8% in our study population. In the multivariable logistic regression model, younger age (OR=1.175, P<0.001) and higher education level (OR=2.142, P=0.040) were the main determinants of non-immune status. However, hepatitis A immunity was independent of gender, monthly family income, water supply source, residential area and underlying liver disorder.Conclusion: Although a significant proportion of liver transplant recipients in this study showed evidence of natural immunity to hepatitis A, a considerable proportion of younger patients and those with a higher level of education were non-immune. The results of this study signify the importance of screening for hepatitis A immunity in this at-risk population of patients and the need for vaccinating non-immune patients.


Antecedentes: La hepatitis A aguda suele ser una enfermedad viral autolimitada, pero puede ser grave e incluso mortal en grupos especiales de pacientes, incluidos aquellos con enfermedad hepática crónica y los receptores de un trasplante de hígado. Para tomar las medidas preventivas adecuadas, es importante determinar el estado inmunológico frente al virus de la hepatitis A en pacientes con riesgo de sufrir resultados clínicos graves después de la infección. Para evaluar la necesidad de inmunización contra la hepatitis A, nuestro objetivo fue determinar el estado inmunológico contra la hepatitis A en una población de receptores de trasplante de hígado. También investigamos la asociación entre el estado inmunológico de la hepatitis A y factores demográficos como la edad y el sexo, la enfermedad hepática subyacente, la fuente de agua potable, el área geográfica de residencia y el nivel socioeconómico.Métodos: este estudio transversal se realizó en 242 receptores de trasplantes de hígado alogénicos en el hospital de trasplantes de órganos “Abu Ali Sina” en Shiraz, Irán, entre enero de 2017 y abril de 2017. El nivel de inmunidad se evaluó mediante kits de detección de anticuerpos contra la hepatitis A.Resultados: La tasa de inmunidad contra la hepatitis A se detectó como 88,8% en nuestra población de estudio. En el modelo de regresión logística multivariable, la edad más joven (OR=1,175, p<0,001) y el nivel de educación superior (OR=2,142, p=0,040) fueron los principales determinantes del estado no inmunitario. Sin embargo, la inmunidad contra la hepatitis A fue independiente del sexo, el ingreso familiar mensual, la fuente de suministro de agua, el área residencial y la enfermedad hepática subyacente.

RESUMO

BACKGROUND: Acute hepatitis A is usually a self-limited viral disease but can be severe and even fatal in special groups of patients including those with chronic liver disease and recipients of liver transplantation. To take appropriate preventive measures, it is important to determine the immune status against the hepatitis A virus in patients at risk of grave clinical outcomes following infection. To assess the need for immunization against hepatitis A, we aimed to determine the immune status against hepatitis A in a population of liver transplant recipients. We also investigated the association between hepatitis A immune status and demographic factors such as age and sex, underlying liver disease, source of drinking water, geographical area of residence and socioeconomic status. METHODS: This cross-sectional study was performed on 242 recipients of allogenic liver transplants at Abu Ali Sina Organ Transplant Hospital in Shiraz, Iran, between January 2017 and April 2017. The level of immunity was assessed using hepatitis A antibody detection kits. RESULTS: The rate of immunity against hepatitis A was detected as 88.8% in our study population. In the multivariable logistic regression model, younger age (OR=1.175, P<0.001) and higher education level (OR=2.142, P=0.040) were the main determinants of non-immune status. However, hepatitis A immunity was independent of gender, monthly family income, water supply source, residential area and underlying liver disorder. CONCLUSION: Although a significant proportion of liver transplant recipients in this study showed evidence of natural immunity to hepatitis A, a considerable proportion of younger patients and those with a higher level of education were non-immune. The results of this study signify the importance of screening for hepatitis A immunity in this at-risk population of patients and the need for vaccinating non-immune patients.
