Background and Aims: Obesity is considered a risk factor for perioperative complications, but its effect on patients undergoing liver transplantation (LT) remains unclear. This study was conducted to analyze the impact of obesity on early morbidity and mortality risk following LT., Methods: A multicenter study of outcomes in patients submitted to LT between 2009 and 2019 was conducted. Recipients were stratified into obese (BMI ≥ 30 kg/m2) and nonobese patients (BMI < 30 kg/m2). Early postoperative complications were compared and 30-day and 1-year patient and graft survival were assessed by Kaplan-Meier method. Primary graft nonfunction (PGNF) was defined as the presence of total bilirubin > 10 mg/dl, INR > 1.6 or ALT > 2000 U/l within the first week after LT., Results: A total of 1608 patients were included after applying exclusion criteria, nonobese (1149, 71.46%) and obese patients (459, 28.54%). There were no significant differences in age, sex, Model for End-stage Liver Disease, Charlson comorbidity score, ethnicity, waiting list time and ischemia time. There were significantly higher rates of vascular (17.58% vs 23.53%, P = 0.021) and biliary complications (27.68% vs 35.73%, P = 0.006) and PGNF (11.40% vs 12.20%, P = 0.021) in obese patients. There was a significantly increased risk for long-term graft failure; however, there was no significant difference in patient survival after LT., Conclusion: Obese patients have significantly increased morbidity in terms of vascular and biliary complications and PGNF after LT. They have a higher risk for worse 1-year graft survival in comparison to controls., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Background & Aims: The evidence suggests that most vulnerable subjects to COVID-19 infection suffer from patients with comorbidities or immunosuppression, including liver transplant recipients. Liver graft dysfunction may be a rare complication. Some patients complain about the post-COVID-19 syndrome. The aim of this study was to assess medium- and short-term outcomes in liver transplant patients., Patients and Methods: A retrospective case series was performed at a tertiary referral center. We screened 845 patients who had liver transplant (LT) in our center. All consecutive LT patients with COVID-19 during the Spanish outbreak from March 2020 to April 2021 were included. Demographics, pre-existing comorbidities, clinical and radiological data of COVID-19 infection, complications, and liver graft function were assessed at diagnosis and 3-month follow-up., Results: Overall, 20 LT patients were diagnosed with confirmed COVID-19. We included 16 patients that met the inclusion criteria, 8 nonhospitalized (50%) and 8 (50%) hospitalized patients were analyzed. The median follow-up was 5.33 months (IQR 3.06-8.26). One patient died during the follow-up. All patients presented some grade of respiratory or functional symptoms. Dyspnea and fatigue were the most prevalent symptoms during the 3-month follow-up. No liver graft dysfunction were reported despite of partial immunosuppression withdrawal in four patients (25%). One patient had cardiovascular complications., Conclusions: Our results suggest the presence of post-COVID-19 syndrome with mild residual physical and psychological dysfunction in this subgroup of patients at 3 months after COVID-19. However, no cases of loss or liver graft dysfunction were reported., (© 2021 Indian National Association for Study of the Liver. Published by Elsevier B.V. All rights reserved.)

Intestinal bacterial overgrowth (IBD) is very frequent in patients with chronic hepatopathies. Causes of IBO, although not entirely known, principally are: the hepatopathy, the alcoholism and the alterations produced by these two factors, such as achylia (and above all hypochlorhydria), decrease in the secretion of IgA, and malnutrition. On the other hand, the IBO increases the severity of the hepatopathy and frequently produces a bacterial peritonitis. All these data suggest that the IBO play an important role increasing the hepatopathy severity and consequently is a factor to bear in mind.
