RESUMO
2023 has been marked by numerous advancements in the fields of hepatology, liver transplantation, gastroenterology, and interventional endoscopy. These developments hold the promise of changing our daily practice while enhancing the diagnosis and treatment of various hepatic and gastroenterological conditions. Additionally, the European Association for the Study of the Liver (EASL) has issued recommendations for the management of hepatitis delta, acute-on-chronic liver failure, liver diseases of pregnancy, and intrahepatic cholangiocarcinoma. Risankizumab was approved by Swiss Authorities for patients with Crohn's disease and dupilumab was approved for patients with eosinophilic esophagitis. The European Society of Gastrointestinal Endoscopy (ESGE) has revised its recommendations regarding Barrett's esophagus.
2023 a été marquée par de nombreuses avancées dans le domaine de l'hépatologie, de la transplantation hépatique, de la gastroentérologie et de l'endoscopie interventionnelle. Ces développements promettent de changer notre pratique quotidienne dans le but d'améliorer le diagnostic et le traitement de nombreuses affections hépatiques et gastroentérologiques. En outre, la Société européenne d'hépatologie (EASL) a émis des recommandations pour la prise en charge de l'hépatite delta, de l'insuffisance hépatique aiguë sur chronique, des complications hépatiques de la grossesse et du cholangiocarcinome intrahépatique. Le risankizumab a été approuvé par Swissmedic pour le traitement de la maladie de Crohn et le dupilumab pour les patients avec Åsophagite à éosinophiles. La Société européenne d'endoscopie a mis à jour ses recommandations concernant l'Åsophage de Barrett.

Simultaneous combined transplantation (SCT), i.e. the transplantation of two solid organs within the same procedure, can be required when the patients develop more than one end-stage organ failure. The development of SCT over the last 20 years could only be possible thanks to progress in the surgical techniques and in the perioperative management of patients in an ageing population. Performing such major transplant surgeries from the same donor, in a short amount of time, and in critical pathophysiological conditions, is often considered to be counterbalanced by the immune benefits expected from these interventions. However, SCT includes a wide array of different transplant combinations, with each time a different immunological constellation. Recent research offers new insights into the immune mechanisms involved in these different settings. Progress in the understanding of these immunological intricacies help to address the optimal induction and maintenance immunosuppressive treatment strategies. In this review, we summarize the different immunological benefits according to the type of SCT performed. We also incorporate the main outcomes according to the immunological risk at transplantation, and the deleterious impact of preformed or de novo donor-specific antibodies (DSA) in the different types of SCT. Finally, we propose comprehensive and evidence-based induction and maintenance immunosuppression strategies guided by the type of SCT.
RESUMO
The use of direct alcohol biomarkers (ethylglucuronide and phosphatidylethanol) has recently been implemented in a clinical setting. Due to their low alcohol detection threshold, high sensitivity, and specificity, these tools are very useful in the pre- and post-liver transplantation setting, where the history and physical signs are not always reliable. However, the interpretation of the results can sometimes be misleading and must be integrated into a global clinical evaluation and, more importantly, in the clinical context of each patient. We present here a case report illustrating a false-positive hair ethylglucuronide caused by the application of a capillary gel in an abstinent patient after liver transplantation. This reminds us that even the most accurate laboratory tests must be interpreted with caution.
