RESUMO

BACKGROUND: The established use of non-selective beta-blockers (NSBB) in the primary and secondary prevention of esophageal varices has recently been questioned in the subgroup of patients with diuretic-refractory ascites. OBJECTIVE: Critically analyze the body of evidence on the topic in order to assist clinical decisions. METHODS: A literature review was carried out in the Pubmed® and Scielo® databases. In total, 20 articles between 2010 and 2023 were read by independent researchers. CONCLUSION: It remains doubtful whether the use of NSBB is deleterious in cirrhotic patients with refractory ascites, however our literature review allows us to conclude that these drugs should not be proscribed in these patients. On the contrary, a doctor-patient decision based on tolerability and hemodynamic parameters certainly seems to be a safe conduct.

RESUMO

Cirrhosis is considered a growing cause of morbidity and mortality, which represents a significant public health problem. Currently, there is no effective treatment to reverse cirrhosis. Treatment primarily centers on addressing the underlying liver condition, monitoring, and managing portal hypertension-related complications, and evaluating the potential for liver transplantation in cases of decompensated cirrhosis, marked by rapid progression and the emergence of complications like variceal bleeding, hepatic encephalopathy, ascites, malnutrition, and more. Malnutrition, a prevalent complication across all disease stages, is often underdiagnosed in cirrhosis due to the complexities of nutritional assessment in patients with fluid retention and/or obesity, despite its crucial impact on prognosis. Increasing emphasis has been placed on the collaboration of nutritionists within hepatology and Liver transplant teams to deliver comprehensive care, a practice that has shown to improve outcomes. This review covers appropriate screening and assessment methods for evaluating the nutritional status of this population, diagnostic approaches for malnutrition, and context-specific nutrition treatments. It also discusses evidence-based recommendations for supplementation and physical exercise, both essential elements of the standard care provided to cirrhotic patients.

RESUMO

• In compensated cirrhosis, using non-invasive methods would exempt the patient from the need of an endoscopy. • The Baveno VII presented the "rule of 5" for Vibration-Controlled Transient Elastography; liver stiffness measurement ≤15 kPa and platelets >150.000/mm3 exclude clinically significant portal hypertension (CSPH), while when ≥25 kPa is highly suggestive of CSPH. • Spleen stiffness measurement has been proposed as a more specific technique to predict the presence of CSPH. • Elastography has gained prestige in the non-invasive evaluation of patients with advanced chronic liver disease by allowing prophylactic measures to be taken when suggesting the presence of CSPH. This is a narrative review that aims to discuss the importance of elastographic methods in the evaluation of clinically significant portal hypertension (CSPH) in cirrhotic patients, where the authors propose an algorithm for evaluating these patients. In compensated advanced chronic liver disease, the goal is to prevent the development of CSPH and, in those already with CSPH, prevent the appearance of gastroesophageal varices (GEV) and other complications of portal hypertension. In compensated cirrhosis, the prevalence of GEV is 30-40%, of which 10-20% are at risk of bleeding. Therefore, using non-invasive methods would exempt the patient from the need of an endoscopy. Hepatic Elastography is a non-invasive, safe, reproducible method, available through many techniques: Vibration-Controlled Transient Elastography (VCTE), Shear Wave Elastography (SWE) and Magnetic Resonance Elastography (MRE). The Baveno VII presented the "rule of 5" for VCTE: liver stiffness measurement (LSM) ≤15 kPa and platelets >150.000/mm3 exclude CSPH, while an LSM ≥25 kPa is highly suggestive of CSPH. Also, the "rule of 4" for SWE has been proposed: patients with ≥17 kPa could be considered as having CSPH. At last, spleen stiffness measurement (SSM) has been proposed as a more specific technique to predict the presence of CSPH. In conclusion, elastography has gained prestige in the non-invasive evaluation of patients with advanced chronic liver disease by allowing prophylactic measures to be taken when suggesting the presence of CSPH.

RESUMO

Hepatosplenic schistosomiasis (HSS) is a serious complication of chronic schistosomiasis that can result in portal hypertension and variceal bleeding. ß-blockers, a class of medications commonly used to treat hypertension and other cardiovascular conditions, have been investigated for their potential use in preventing variceal bleeding in HSS. Several studies have shown that ß-blockers can reduce portal pressure and prevent variceal bleeding effectively in these patients. However, there are limited data on the long-term efficacy and safety of ß-blockers in this setting, and further research is needed to determine the optimal use of these medications. This review summarizes the evidence supporting current recommendations of ß-blocker use in patients with HSS.

RESUMO

Our objective was to develop a diagnostic test to predict the etiology of Variceal Upper Gastrointestinal Bleeding (VUGIB). We conducted a retrospective cohort study. Medical records of patients over 18 years of age with Upper Gastrointestinal Bleeding (UGIB) who attended the emergency service of Hospital Cayetano Heredia (HCH) in Lima-Peru between 2019 and 2022 were reviewed; demographic, laboratory and clinical data were collected. Subsequently, predictive variables of variceal upper gastrointestinal bleeding (VUGIB) were identified using multiple logistic regression. Each variable with predictive capacity was assigned a score with a cut-off point and served to build a predictive scale for VUGIB. 197 medical records of patients with UGIB were included, of which 127 (64%) had non-variceal bleeding, and 70 (36%), variceal. Four independent predictors were identified: hematemesis (red vomit) (OR: 4,192, 95% CI: 1.586-11.082), platelet count (OR: 3.786, 95% CI: 1.324-10.826), history of UGIB (OR: 2.634, 95% CI: 1.017-6.820), signs of chronic liver disease (OR: 11.244, 95% CI: 3.067-35.047), with which a predictive scale was constructed, with a cut-off point >7 and ≤7; which showed a sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative of 58.6%, 90.6%, 77.4%, 79.9%, 6.20, and 0.46 respectively. In conclusion, the predictive scale with a cut-off point >7 is useful for predicting the presence of VUGIB in patients who attend the emergency room for UGIB.

RESUMO

•Most data on the natural history of portal hypertension come from studies in adults. •The morbidity rate of upper gastrointestinal bleeding in children with portal hypertension tend to be underestimated. •This study showed the relevance of morbidity rates after variceal hemorrhage in pediatric patients, especially those with cirrhosis. •Patients with hemodynamic instability requiring blood transfusion or expansion on admission are at increased risk of complications secondary to upper gastrointestinal bleeding and should be closely monitored. Background - Most data on the natural history of portal hypertension come from studies in adults. The morbidity rate of upper gastrointestinal bleeding (UGIB) in children with portal hypertension has not been systematically characterized. Objective - To describe the morbidity and mortality of UGIB in pediatric patients with portal hypertension and identify predictive factors for the occurrence of its main complications. Methods - This retrospective study included pediatric patients with cirrhotic portal hypertension or with extrahepatic portal vein obstruction (EHPVO). Mortality and UGIB complications within a period of up to 6 weeks of the bleeding were investigated. To determine the predictive factors of morbidity, a multivariate analysis was performed using logistic regression; all results were considered significant at P<0.05. Results - A total of 86 patients (51.2% with EHPVO and 48.8% with cirrhosis) had 174 bleeding events. Ascites was the most common complication (43.1% of all cases), being more prevalent in patients with cirrhosis (P<0.001). Cirrhosis was a predictor of the occurrence of any morbidity (OR 20.3). The need for blood transfusion was predictor of at least one complication (OR 5.8), ascites (OR 7.2) and infections (OR 3.8) in the general group and at least one complication (OR 11.3) and ascites (OR 5.8) in cirrhotic patients. The need for expansion was a predictor of any morbidity (OR 4.6) and infections (OR 3.9) in the general group, in addition to being predictor of infection in cirrhotic patients (OR 5.4). There were no deaths from UGIB in the six weeks post-bleeding. Conclusion - The study showed the relevance of morbidity after UGIB in pediatric patients with portal hypertension, especially in those with cirrhosis. The patients with hemodynamic instability requiring blood transfusion or expansion on admission are at increased risk of complications related to upper gastrointestinal bleeding and should be closely monitored.

RESUMO

BACKGROUND: The management of complex, intra- and extrahepatic portal vein thrombosis (PVT) after liver transplantation (LT) is challenging. Although most of the patients remain asymptomatic or oligosymptomatic in the chronic setting, some of them may develop severe portal hypertension and related complications, notably gastrointestinal (GI) bleeding. In the emergency scenario, clinical and endoscopic treatments as well as intensive support constitute the bases of conservative management, while more definitive treatment options such as surgical shunting and retransplantation are related to high morbidity rates. Transjugular intrahepatic portosystemic shunt (TIPS) was largely considered of limited role due to technical difficulties arising from extensive PVT. Recently, however, new minimally invasive image-guided techniques emerged, allowing portal vein recanalization and TIPS creation simultaneously (TIPS-PVR), even in complex PVT pretransplant patients. METHODS: Herein, we describe a novel indication for TIPS-PVR in a post-LT adolescent presenting with life-threatening, refractory GI bleeding. RESULTS: The patient presented with complete resolution of the hemorrhagic condition after the procedure, with no deterioration of hepatic function or hepatic encephalopathy. Follow-up Doppler ultrasound after TIPS-PVR showed normal hepatopetal venous flow within the stents, and no evidence of complications, including intraperitoneal or peri splenic bleeding. CONCLUSIONS: This report describes the feasibility of TIPS-PVR in the post-LT scenario complicated by extensive PVT. In this case, a complete resolution of the life-threatening GI bleeding was achieved, with no major complications. Other patients with complex chronic PVT might benefit from the use of the described technique, but further studies are required to determine the correct timing and indications of the procedure, eventually before the occurrence of life-threatening complications.

RESUMO

INTRODUCTION AND OBJECTIVES: Cirrhotic patients with acute variceal hemorrhage (AVH) have high short-term mortality. Established prognostic scores are seldom applicable clinically, partially because they need external validation or contain subjective variables. We aimed to develop and validate a practical prognostic nomogram based on objective predictors to predict prognosis for cirrhotic patients with AVH. PATIENTS AND METHODS: We enrolled 308 AVH patients with cirrhosis from our center as the derivation cohort to develop a new nomogram using logistic regression and validated it in cohorts of patients from Medical Information Mart for Intensive Care (MIMIC) III (n = 247) and IV (n = 302). RESULTS: International normalized ratio (INR), albumin (ALB) and estimated glomerular filtration rate (eGFR) were identified as predictors for inpatient mortality and a nomogram was constructed based on them. The nomogram discriminated well in both derivation and MIMIC-III/-IV validation cohorts with the area under the receiver operating characteristic curves (AUROCs) of 0.846 and 0.859/0.833, respectively and showed a better agreement between expected and observed outcomes (Hosmer-Lemeshow tests, all comparisons, P > 0.05) than other scores in all cohorts. Our nomogram had the lowest Brier scores (0.082/0.114/0.119 in training/MIMIC-III/MIMIC-IV) and highest R2 (0.367/0.393/0.346 in training/MIMIC-III/MIMIC-IV) compared to the recalibrated model for end-stage liver disease (MELD), MELD-hepatic encephalopathy (MELD-HE) and cirrhosis acute gastrointestinal bleeding (CAGIB) scores in all cohorts. CONCLUSIONS: We developed a practical prognostic nomogram using easily verified indicators available in initial patient evaluation, which may serve as a reliable tool to accurately predict inpatient mortality for cirrhotic patients with AVH.

RESUMO

INTRODUCTION: Cirrhosis is one of the ten leading causes of death in the Western hemisphere and entails a significant cost of health care. OBJECTIVE: To describe the sociodemographic, clinical, and laboratory characteristics of patients older than 18 years who received care for acute decompensation of cirrhosis in the emergency services of three highly complex centers in Medellín, Colombia. MATERIALS AND METHODS: This was an observational retrospective cohort study from clinical records. The results were analyzed by frequency measures and represented in tables and graphics. RESULTS: In total, 576 clinical records met the inclusion criteria; 287 were included for analysis, and 58.9% were men, with an average age of 64 (± 13.5) years. The most frequent causes of cirrhosis were alcohol intake (47.7%), cryptogenic or unspecified etiology (29.6%), and non-alcoholic fatty liver disease (9.1%). The main reasons for visiting the emergency department were the presence of edema and/or ascites (34.1%), suspicion of gastrointestinal bleeding (26.5%), abdominal pain (14.3%) and altered mental status (13.9%). The most frequent clinical manifestations of an acute decompensation of cirrhosis were ascites (45.6%), variceal hemorrhage (25.4%), hepatic encephalopathy (23.0%), and spontaneous bacterial peritonitis (5.2%). During their treatment, 56.1% of the patients received intravenous antibiotics; 24.0%, human albumin; 24.0%, vasoactive support, and 27.5%, blood products; 21.3% required management in an intensive or intermediate care unit, registering 53 deceased patients for a mortality of 18.5%. CONCLUSION: Patients who consult the emergency services due to acute decompensation of cirrhosis demand a high amount of health resources, frequently present associated complications, and a high percentage requires management in critical care units and shows a high in-hospital mortality rate.


Introducción. La cirrosis hace parte de las diez primeras causas de muerte en el hemisferio occidental y acarrea un importante costo en salud. Objetivo. Describir las características sociodemográficas, clínicas y de laboratorio, de los pacientes mayores de 18 años que recibieron atención por descompensación aguda de la cirrosis en los servicios de urgencias de tres centros de alta complejidad en Medellín, Colombia. Materiales y métodos. Se trata de un estudio observacional de cohorte. Los resultados se analizaron mediante medidas de frecuencia, y se representaron en tablas y gráficas. Resultados. En total, en 576 registros clínicos se cumplieron los criterios de inclusión; se incluyeron 287 para el análisis. El 58,9 % fueron hombres, con edad promedio de 64 (±13,5) años. Las causas más frecuentes de cirrosis fueron: ingestión de alcohol (47,7 %), criptogénica o inespecífica (29,6 %) y enfermedad por hígado graso no alcohólico (9,1 %). Los principales motivos de consulta fueron: presencia de edemas, ascitis o ambas (34,1 %), sospecha de hemorragia digestiva (26,5 %), dolor abdominal (14,3 %) y alteración del estado mental (13,9 %). Los diagnósticos de complicación aguda más frecuentes fueron ascitis (45,6 %), hemorragia digestiva por várices esofágicas (25,4 %), encefalopatía hepática (23,0 %) y peritonitis bacteriana espontánea (5,2 %). El 56,1 % de los pacientes recibió antibióticos; el 24,0 %, albúmina humana; el 24,0 % medicamentos, y el 27,5 % hemoderivados. En el 21,3 % de los casos, se requirió hospitalización en la unidad de cuidados intensivos o en la de cuidados intermedios. Se registraron 53 decesos, para una mortalidad del 18,5 %. Conclusiones. Los pacientes que consultan a los servicios de urgencias por una descompensación aguda de la cirrosis demandan una gran cantidad de recursos, frecuentemente presentan complicaciones asociadas, requieren manejo en unidades de cuidado crítico y evidencian una alta tasa de mortalidad.
