- Acute Liver Failure: An Up-To-Date ApproachPublication . Cardoso, FS; Marcelino, P; Bagulho, L; Karvellas, CAcute liver failure is a rare but potentially devastating disease. Throughout the last few decades, acute liver failure outcomes have been improving in the context of the optimized overall management. This positive trend has been associated with the earlier recognition of this condition, the improvement of the intensive care unit management, and the developments in emergent liver transplantation. Accordingly, we aimed to review the current diagnostic and therapeutic approach to this syndrome, especially in the intensive care unit setting.
- Epidemiology of Acute Liver Failure from a Regional Liver Transplant Center in PortugalPublication . Simões, C; Santos, S; Vicente, M; Cardoso, FSBackground and Aims: Acute liver failure (ALF) is a rare disease with potentially high mortality rates. We aimed to study the recent epidemiology of ALF in one of the Portuguese liver transplant (LT) regions. Methods: We assessed a retrospective cohort including 34 consecutive patients with ALF admitted to the intensive care unit (ICU) of Curry Cabral Hospital (Lisbon, Portugal) between October 2013 and December 2016. Results: The median age (IQR) was 49 (31-67) years, and 21 (62%) of the cohort were female. Non-paracetamol etiologies were found in 29 patients (85%). On ICU admission, grade 3-4 hepatic encephalopathy developed in 10 patients (29%); invasive mechanical ventilation, vasopressors, and renal replacement therapy were required for 8 (24%), 7 (21%), and 5 (15%) of the patients, respectively; the King's College criteria (KCC) were fulfilled by 16 patients (47%). Of the 15 (44%) nontransplanted patients, 11 (73%) died during their hospital stay. Of the 19 (56%) transplanted patients, 4 (21%) died during their hospital stay. KCC were not associated with hospital mortality (p = 0.97), but they were significantly associated with LT (p = 0.008). Conclusions: In a Portuguese cohort of patients with ALF, non-paracetamol etiologies were predominant. Hospital mortality was much lower amongst transplanted patients.

- Post Liver Transplantation Delirium Assessment Using the CAM-ICU-7 Scale: a Cohort AnalysisPublication . Cardoso, FS; Kok, B; Dong, V; Kim, M; Karvellas, CBackground: We applied the Confusion Assessment Method (CAM)-Intensive Care Unit (ICU)-7 delirium scale to patients who underwent liver transplant (LT). Methods: Retrospective cohort including patients who underwent LT for cirrhosis admitted to the ICU from June 2013 to June 2016 at the University of Alberta Hospital, Canada. Delirium was assessed using the CAM-ICU-7 scale (0-7 points) twice daily on days one and 3 post LT, with the highest score being considered. Primary endpoint was hospital mortality. Results: Among all patients, 101/150 (67.3%) were men and mean age was 52.4 (SD 11.8) years. On days 1 and 3 post LT, mean CAM-ICU-7 scores were 1.8 (SD 1.3) and 1.6 (SD 1.8), respectively. Therefore, on days 1 and 3 post LT, 38/150 (25.3%) and 26/95 (27.4%) patients had delirium. While delirium on day 3 post LT was associated with higher hospital mortality (11.5% versus 0%; p = 0.019), it was not associated with length-of-hospital stay (29.2 versus 34.4 days; p = 0.36). Following adjustment for APACHEII score, delirium on day 3 post LT was associated with higher odds of hospital mortality (adjusted odds ratio [aOR] 1.89 [95% CI 1.02-3.50]). Following adjustment for Glasgow Coma Scale and mechanical ventilation, serum creatinine was associated with higher odds of delirium on day 3 post LT (aOR 2.02 [95% CI 1.08-3.77]). Conclusions: Using the CAM-ICU-7 scale, delirium was diagnosed in a fourth of patients who underwent LT. Delirium on day 3 post LT was associated with higher odds of hospital mortality.
- The Impact of Donor Risk Index, Recipients’ and Operative Characteristics on Post Liver Transplant One-Year Graft Failure: A Cohort AnalysisPublication . Cardoso, FS; Bagulho, L; Coelho, JS; Lamelas, J; Mateus, E; Mendes, M; Glória, H; Ribeiro, V; Mega, R; Pena, A; Pinto Marques, H; Germano, N; Nolasco, F; Perdigoto, R; Martins, ABackground and Aims: The donor risk index (DRI) quantifies donor-related characteristics potentially associated with increased risk of early graft failure. We aimed to assess the impact of the DRI, recipient and perioperative factors on post liver transplant (LT) outcomes. Methods: This was a singlecenter retrospective cohort study including all adult (≥18 years) patients who underwent LT from 01/2019 to 12/2019 at Curry Cabral Hospital, Lisbon, Portugal. Primary endpoint was 1-year graft failure post LT. Associations were studied with logistic regression. Results: A total of 131 cadaveric donor LT procedures were performed in 116 recipients. Recipients’ median (IQR) age was 57 (47–64) years and 101/131 (77.1%) were males. Cirrhosis was the underlying etiology in 95/131 (81.2%) transplants. Based on 8 predefined donors’ characteristics, median (IQR) DRI was 1.96 (1.67–2.16). Following adjustment for MELDNa score pre LT and SOFA score (adjusted odds ratio [aOR], 95% confidence interval [CI] = 0.91 [0.56–1.47]) or lactate (aOR [95% CI] = 2.76 [0.71–10.7]) upon intensive care unit (ICU) admission post LT, DRI was not associated with 1-year graft failure. However, higher SOFA score (aOR [95% CI] = 1.20 [1.05–1.37]) or lactate (aOR [95% CI] = 1.27 [1.10–1.46]) upon ICU admission post LT were independently associated with higher odds of 1-year graft failure. Conclusions: In a recent cohort of patients who underwent LT, DRI, despite being high, was not associated with 1-year graft failure, but SOFA score or lactate upon ICU admission post LT were.
- Variation in the Care of Acute Liver Failure: A Survey of Intensive Care ProfessionalsPublication . Cardoso, FS; Mcphail, MJ; Karvellas, CJ; Fuhrmann, V; Germano, N; Auzinger, GIntroduction: Acute liver failure (ALF) is a rare disease with potentially high mortality. We sought to assess the individual approach to ALF by intensive care unit (ICU) professionals. Methods: Cross-sectional survey of ICU professionals. Web-based survey capturing data on respondents' demographics, characteristics of patients with ALF admitted to ICU, and their management. Results: Among 204 participants from 50 countries, 140 (68.6%) worked in Europe, 146 (71.6%) were intensivists, 142 (69.6%) admitted <25 patients with ALF per year, and 166 (81.8%) reported <25% of patients had paracetamol-related ALF. On patients' outcomes, 126 (75.0%) reported an emergency liver transplantation (ELT) rate <25% and 140 (73.3%) a hospital mortality rate <50%. The approach to ALF in the ICU varied with age, region, level of training, type of hospital, and etiology (prescribing N-acetylcysteine for paracetamol toxicity, triggers for endotracheal intubation, measurement of and strategies for lowering serum ammonia, extracorporeal device deployment, and prophylactic antibiotics). Conclusions: The management of patients with ALF by ICU professionals differed substantially concerning the relevant clinical measures taken. Further education and high-quality research are warranted.
