RESUMEN
BACKGROUND: Women who have undergone liver transplantation (LT) enjoy better health, and possibility of childbearing. However, maternal and graft risks, optimal immunosuppression, and fetal outcome is still to clarify. AIM: Aim of the study was to assess outcomes of pregnancy after LT at national level. METHODS: In 2019, under the auspices of the Permanent Transplant Committee of the Italian Association for the Study of the Liver, a multicenter survey including 14 Italian LT-centers was conducted aiming at evaluating the outcomes of recipients and newborns, and graft injury/function parameters during pregnancy in LT-recipients. RESULTS: Sixty-two pregnancies occurred in 60 LT-recipients between 1990 and 2018. Median age at the time of pregnancy was 31-years and median time from transplantation to conception was 8-years. During pregnancy, 4 recipients experienced maternal complications with hospital admission. Live-birth-rate was 100%. Prematurity occurred in 25/62 newborns, and 8/62 newborns had low-birth-weight. Cyclosporine was used in 16 and Tacrolimus in 37 pregnancies, with no different maternal or newborn outcomes. Low-birth-weight was correlated to high values of AST, ALT and GGT. CONCLUSION: Pregnancy after LT has good outcome; however, maternal complications and prematurity may occur. Compliance with the immunosuppression is fundamental to ensure the stability of graft function and prevent graft-deterioration.

Malnutrition and sarcopenia have a high prevalence in cirrhotic patients. Frailty generally overlaps with malnutrition and sarcopenia in cirrhosis, leading to increased morbidity and mortality. Rapid nutritional screening assessment should be performed in all patients with cirrhosis, and more specific tests for sarcopenia should be performed in those at high risk. The pathogenesis of malnutrition in cirrhosis is complex and multifactorial and it is not just due to reduction in protein and calorie intake. Nutritional management in malnourished patients with cirrhosis should be undertaken by a multidisciplinary team to achieve adequate protein/calorie intake. While the role of branched-chained amino acids remains somewhat contentious in achieving a global benefit of decreasing mortality- and liver-related events, these latter and vitamin supplements, are recommended for those with advanced liver disease. Novel strategies to reverse sarcopenia such as hormone supplementation, long-term ammonia-lowering agents and myostatin antagonists, are currently under investigation. Malnutrition, sarcopenia and frailty are unique, inter-related and multidimensional problems in cirrhosis which require special attention, prompt assessment and appropriate management as they significantly impact morbidity and mortality.

Portal hypertension is a clinical syndrome characterized by an increase in the portal pressure gradient, defined as the gradient between the portal vein at the site downstream of the site of obstruction and the inferior vena cava. The most frequent cause of portal hypertension is cirrhosis. In patients with cirrhosis, portal hypertension is the main driver of cirrhosis progression and development of hepatic decompensation (ascites, variceal hemorrhage and hepatic encephalopathy), which defines the transition from compensated to decompensated stage. In decompensated patients, treatments aim at lowering the risk of death by preventing further decompensation and/or development of acute-on-chronic liver failure. Decompensated patients often pose a complex challenge which typically requires a multidisciplinary approach. The aims of the present review were to discuss the current knowledge regarding interventional treatments for patients with portal hypertension complications as well as to highlight useful information to aid hepatologists in their clinical practice. Specifically, we discussed the indications and contraindications of transjugular intra-hepatic portosystemic shunt and for the treatment of gastro-esophageal variceal hemorrhage in patients with decompensated cirrhosis (first section); we reviewed the use of interventional treatments in patients with hepatic vein obstruction (Budd-Chiari Syndrome) and in those with portal vein thrombosis (second section); and we briefly comment on the most frequent applications of selective splenic embolization in patients with and without underlying cirrhosis (third section).

Hepatocellular carcinoma (HCC) represents the sixth most commonly diagnosed cancer and the fourth leading cause of cancer-related death worldwide. HCC occurs predominantly in patients with underlying chronic liver disease and cirrhosis, and it presents a poor prognosis in advanced stage. Since its approval, for the following 10 years, sorafenib remained the only systemic agent with proven clinical efficacy for patients with advanced HCC. Recently, more drugs have been studied and several advances in firstline and secondline treatment options should yield significant improvements in survival. Lenvatinib, another tyrosinekinase inhibitor, was found to be non-inferior to sorafenib in terms of overall survival (OS), with significantly better progression-free survival and objective response rate (ORR). The tyrosinekinase inhibitors, regorafenib and cabozantinib, were shown to significantly improve survival in the secondline setting after sorafenib failure. Ramucirumab, a VEGF inhibitor, can also improve survival in the secondline setting among patients with AFP≥400 ng/dL. Moreover, good efficacy was seen in phase I/II trials of immune checkpoint inhibitors as monotherapy. Ongoing trials are evaluating combination immune checkpoint inhibitor and tyrosinekinase inhibitors or VEGF inhibitors for increasing overall survival in this patient population with advanced HCC.

Hepatitis B virus (HBV) is a major health problem worldwide, with approximatively 240 million people living with a chronic HBV infection. HBV chronic infection remains the major cause of hepatocellular carcinoma worldwide, with more than half of HCC patients being chronic HBV carriers, even if underlying mechanisms of tumorigenesis are not totally understood. HBV-related HCC can be prevented by reducing the exposure to HBV by vaccination or by treatment of CHB infection. Current treatment of CHB are Peg-IFN alpha and oral NUCs. Treating HBV infection, either with IFN or NUCs, substantially reduces the risk of HCC development, even if antiviral therapy fails to completely eliminate HCC risk. Among treated patients, cirrhosis, HBeAg negative at baseline and failure to remain in virological remission were associated with an increased risk of HCC. The reduction of the risk of developing HCC during antiviral therapy is largely dependent upon the maintenance of virological remission, since viral load is found to be the most important factor leading to cirrhosis and its complications, including liver cancer development. The question whether Peg-IFN-alpha is superior to NUCs and whether there is a superior agent among NUCs is still controversial. Several studies demonstrated that antiviral therapy with NUCs could reduce the risk of HCC recurrence after curative treatment of HBV-related HCC.

Introduction: Diagnosis of severe hepatitis C recurrence is based on analytical and histological criteria but there is little information about their correlation. Aim: To assess the accuracy of laboratory criteria for the diagnosis of fibrosing cholestatic hepatitis (FCH). Patients and methods: Retrospective analysis of prospectively collected data form HCV positive patients who underwent liver transplantation (LT) between 2000 and 2014 in two European university hospitals. Patients were classified according to laboratory criteria such as FCH, cholestatic hepatitis (CH) and non-cholestatic acute hepatitis (NCAH). Histological characteristics were also evaluated. Results: Seventy patients with acute HCV recurrence within the first year after LT with an available liver biopsy were included in the study. Most patients were male (70%) with a median age of 58 years (50-64) and infected with genotype 1b (71.4%). Median time from LT to diagnosis of recurrence was 2.96 months (2.1-5.3). Thirty-nine patients were classified as FCH, 21 as CH and 10 as NCAH. Marked hepatocyte ballooning and ductular reaction were associated with the presence of FCH with an OR of 4.66 (p=0.047) and 20.58 (p=0.025), respectively. Considering liver biopsy as the gold standard, the sensitivity, specificity, positive and negative predictive values of the analytical criteria were 0.8, 0.5, 0.3 and 0.9, respectively. However, correlation between histological and analytical criteria was poor (k=0.033). Discussion: Analytical criteria may be used to rule out the presence of FCH, but a biopsy is mandatory to confirm the diagnosis. Ductular reaction and hepatocyte ballooning were independent predictors of FCH
Introducción: El diagnóstico de la recurrencia grave de la hepatitis C se basa en criterios histológicos y analíticos. Sin embargo, existe poca información respecto su correlación. Objetivo: Evaluar la precisión de los criterios analíticos el diagnóstico de la hepatitis colestásica fibrosante (HCF). Pacientes y métodos: Análisis retrospectivo de pacientes con una recidiva grave precoz del virus de la hepatitis C (VHC) tras el trasplante hepático (TH) en 2 hospitales universitarios europeos entre 2000-2014. Los pacientes se clasificaron según criterios analíticos en HCF, hepatitis colestásica (HC) y hepatitis aguda no colestásica (HANC). Las características histológicas también fueron evaluadas. Resultados: Se incluyeron 70 pacientes que desarrollaron una recurrencia grave del VHC en el primer año tras TH con una biopsia hepática disponible. La mayoría eran varones (70%) con mediana de edad de 58 años (50-64) y genotipo 1b (71,4%). La mediana de tiempo desde el TH hasta el diagnóstico de la recurrencia fue de 2,96 meses (2,1-5,3). Treinta y nueve pacientes fueron clasificados como HCF, 21 como HC y 10 como HANC. La balonización intensa y reacción ductular se asociaron con HCF con una OR de 4,66 (p=0,047) y 20,58 (p=0,025), respectivamente. Considerando la biopsia hepática como gold standard, la sensibilidad, especificidad y valores predictivos positivo y negativo de los criterios analíticos fueron 0,8, 0,5, 0,3 y 0,9, respectivamente. Sin embargo, la correlación entre ambos fue escasa (k=0,033). Discusión: Los criterios analíticos podrían utilizarse para descartar la presencia de HCF, pero la biopsia sigue siendo obligatoria para el diagnóstico. La reacción ductular y la balonización son predictores de HCF

Bacterial infection (BI) is a common cause of impairment of liver function in patients with cirrhosis, especially in the liver transplant candidates. These patients share an immunocompromised state and increased susceptibility to develop community and hospital-acquired infections. The changing epidemiology of BI, with an increase of multidrug resistant strains, especially in healthcare-associated settings, represents a critical issue both in the waiting list and in the post-operative management. This review focused on the role played by BI in patients awaiting liver transplantation, evaluating the risk of drop-out from the waiting list, the possibility to undergo liver transplantation after recovery from infection or during a controlled infection.
