Liver transplantation (LT) is the only curative treatment for cirrhosis. However, the presence of complications can impact outcomes following LT. Sarcopenia, or muscle mass loss, is highly prevalent in patients with cirrhosis and is associated with longer hospitalization stays and a higher infection rate post-surgery. We aimed to identify patients at higher risk of early sarcopenia post-LT. This retrospective study included 79 cirrhotic patients who underwent LT. Muscle mass was evaluated using the third lumbar spine vertebra skeletal muscle index (SMI) and sarcopenia was defined using established cut-off values. Computerized tomography (CT) scans performed within a six-month peri-operative period (three months pre- and post-LT) were included in the study. Complications and comorbidities were collected and correlated to SMI post-LT and predictive models for SMI post-LT were constructed. The overall prevalence of sarcopenia was 46% and 62% before and after LT, respectively. Newly developed sarcopenia was found in 42% of patients. Post-LT sarcopenia was associated with longer hospital stays (54±37 versus 29±10 days, = 0.002), higher number of infection (3±1 versus 1±2, = 0.027), and greater number of complications (5±2 versus 3±2, < 0.001) compared to absence of sarcopenia. Multivariate analyses showed that the SMI post-LT was independently associated with pre-LT renal function markers, the glomerular filtration rate (GFR) and creatinine (Model 1, GFR: = 0.33; 95% CI 0.04-0.17; = 0.003; Model 2, Creatinine: = -0.29; 95% CI -0.10 to -0.02; = 0.009). The present study highlights the potential role of renal dysfunction in the development and persistence of sarcopenia after LT.
Outcomes of sarcopenic obesity and metabolic syndrome in liver transplant patients.
Mimosa Nguyen, Mélanie Tremblay, Geneviève Huard, An Tang, Christopher Rose, Chantal Bémeur.
Background: Sarcopenia is associated with a worst prognosis in cirrhotic patients after liver transplantation (LT). As patients gain weight and sarcopenia remains after LT, sarcopenic obesity (SO) develops. Metabolic syndrome (MS), a cluster of factors that increase the risk of heart disease and diabetes, is caused by weight gain. There are limited data about the influence of SO and MS in LT recipients. Purpose: The goal of this study was to examine the impact of SO and MS on outcome after LT. Method: In total, 94 cirrhotic patients who underwent LT at the CHUM – Liver Unit were included. Sarcopenia was assessed at the third lumbar level vertebrae using a CT-scan. Obesity was determined using BMI whereas MS was diagnosed using the presence of ³3 modified NCEP ATP III criteria. The prognostic factors were collected 6 months before and during 1 year after LT through medical records and included number of complications, episodes of infections, length of stay, and frequency of readmissions. Result(s): Most of the patients ( 70%) were not obese before LT. Approximately 20% of the patients developed obesity after LT. Among patients who were obese before LT, 40% of the patients remained obese after LT. SO affected 10% and less of the patients before and after LT. Among patients with MS before LT (64%), 40% of them was still affected after LT. Among patients who were not affected by MS before LT, 38% developed MS after LT and one patient remained not affected after LT. Prognostic factors were worst in patients with SO and MS before and after LT. Conclusion(s): SO affected a small proportion of patients while MS was prevalent before and after LT. Nevertheless, these conditions were associated with worst prognosis. Strategies to manage SO and MS could help to improve recovery in patients who have undergone LT.

Background: Non-alcoholic fatty liver disease (NAFLD) is associated with type II diabetes (T2D) and has become the main cause of cirrhosis. Both NAFLD and T2D are associated with cognitive and neurological impairments. T2D has been established as a risk factor for first-time development of overt hepatic encephalopathy (HE) in cirrhotic patients. The onset of HE in diabetic patients with cirrhosis develops earlier compared to cirrhosis patients without T2D. However it remains unclear whether NAFLD-induced cirrhosis increases the risk for HE. The present study aims to address the association between NAFLD, T2D and HE. Methods: Our retrospective study includes 102 cirrhotic patients on the liver transplant list at the Liver Unit of the Montreal University Hospital Center. Patients were classified by etiology of cirrhosis; 1) NAFLD and 2) non-NAFLD. Demographic data, blood biochemistry, clinical information on T2D-related comorbidities and cirrhosis complications (including number and severity of HE episodes) were collected. These factors were statistically associated with HE episodes. Results: Our cohort comprised 20 (19%) NAFLD and 82 (79%) non-NAFLD patients presenting similar MELD and Child-Pugh scores. The prevalence of T2D was higher in NAFLD vs non-NAFLD cirrhotics (15 (75%) vs 24 (29%) respectively) and was associated to co-morbidities such as cardiac disease, dyslipidemia, hypertension and obesity. Among non-NAFLD cirrhotics, 47 (57%) patients had a history of HE whereas 8 (40%) were found in the NAFLD cirrhotics (p>0.05). Since T2D is already known as a risk factor for HE, we subdivided both NAFLD and non-NAFLD groups into non-T2D and T2D subgroups. HE was significantly more prevalent in patients with T2D: in the NAFLD group, 5 (25%) T2D patients had developed an episode of HE compared to 3 (15%) patients without T2D (p<0.05); in the non-NAFLD group, 16 (67%) patients had T2D and HE compared to 31 (53%) HE patients without T2D (p<0.001). Fasting glycemia levels analysis in the 4 sub-groups of patients revealed increased levels in patients with history of HE and T2D, regardless of NAFLD etiology; in the NAFLD group 8.60 ± 0.84 mmol/l in patients with HE and T2D vs 6.00 ± 1.35 mmol/l in patients with HE without T2D (p<0.01); in the non-NAFLD group: 9.23 ± 0.93 mmol/l in patients with HE and T2D vs 5.82 ± 0.27 mmol/l in patients with HE without T2D (p<0.001). Conclusion: Our results sustain the association between T2D and HE and suggest high glucose might play a pathological role in the development of cognitive decline. NAFLD is not a risk factor for the development of HE. These interesting results provide new insights in the role of T2D in the development of HE and further studies are required to understand the underlying mechanisms. Furthermore, identifying patients who are at higher risk of developing HE is imperative to initiate early treatment strategies to protect neurological decline in patients with cirrhosis.

Sarcopenia Pre- and Post-liver Transplantation Implication for Hepatic Encephalopathy.
Mimosa Nguyen, Geneviève Huard, An Tang, Christopher F. Rose, Chantal Bémeur.
BACKGROUND: Muscle wasting (sarcopenia) and hepatic encephalopathy affect 30 to 70% of cirrhotic patients. The presence of sarcopenia may be associated with a worst prognosis and complications, including hepatic encephalopathy, in cirrhotic patients awaiting and after liver transplantation (LT). To this day, few studies have evaluated and followed muscle mass (in terms of quantity and quality) after LT. The goal of this study was to assess the association between the evolution of sarcopenia and the prognosis of cirrhotic patients, including hepatic encephalopathy and neurological complications, before and after LT. METHODS: In total, 94 cirrhotic patients who underwent LT at the Montreal University Hospital Center - Liver Unit were included. Sarcopenia was assessed at the third lumbar level vertebrae using a computed tomography scan (CT-scan). The diagnostic of sarcopenia was based on previously established sex-specific cut-off values of skeletal muscle index. Patients were classified into two groups: (1) persistent or newly developed sarcopenia after LT (Sarc+); (2) resolved sarcopenia or absence of sarcopenia before and after LT (Sarc-). Muscle quality (myosteatosis) was assessed by calculating intramuscular adipose tissue content. The prognostic factors were collected 6 months before and during 1 year after LT through medical records and included the number of complications, the presence of hepatic encephalopathy and the episodes of infections, the length of stay, and the frequency of readmissions. RESULTS: Sarcopenia persisted or was newly developed (Sarc+) in 62% of the patients (n = 58). It remained absent or was resolved after LT in 38% of the patients (n = 35). Muscle quality was significantly decreased post-LT (P = 0.034). The group Sarc+ experienced more complications pre-LT (P = 0.012) and post-LT (P < 0.001), infections post-LT (P = 0.006) and readmissions (P = 0.048) compared to the group Sarc-. The length of stay was longer for the group Sarc+ as opposed to the group Sarc- (P < 0.001). Hepatic encephalopathy was present in 83% of patients pre-LT whereas 17% experienced persistent neurological complications post-LT. CONCLUSIONS: Persistent and newly developed sarcopenia after LT appear to have negative outcomes on the prognosis of patients. Interventional strategies to optimize, increase or preserve muscle mass could help to improve post-operative recovery as well as the quality of life in patients who have undergone LT.

Introduction : La sarcopénie affecte jusqu’à 70% des patients atteints d’une maladie hépatique chronique (cirrhose). Sa présence a été associée à une qualité de vie détériorée. Par ailleurs, elle pourrait influencer le pronostic des patients cirrhotiques avant et après la transplantation hépatique (TH), seul traitement curatif pour la cirrhose à ce jour. Peu d’études ont étudié l’évolution de la sarcopénie après la TH. Le but de cette étude était d’évaluer l’évolution de la sarcopénie et son association avec le pronostic des patients cirrhotiques pré- et post-TH. Méthodes : L’évaluation de la masse musculaire a été effectuée chez 94 patients du département d’hépatologie du CHUM ayant reçu la TH entre le 5 juin 2012 et le 30 avril 2017. Elle était évaluée en utilisant l’index musculaire squelettique lequel est basé sur l’analyse de l’examen radiologique de tomodensitométrie au niveau de la 3e vertèbre lombaire. Par la consultation des dossiers médicaux, les critères de pronostic étaient évalués durant l’année suivant la TH et comprenaient le nombre de complications, les épisodes d’infection, la durée de l’hospitalisation et la fréquence des réadmissions. Résultats : La sarcopénie a persisté ou est apparue (Sarc+) chez 62% des patients (n=58) alors qu’elle a régressé ou est demeurée absente (Sarc-) chez 38% des patients (n=35). Le groupe Sarc+ a eu davantage de complications avant la TH (p=0,012) et après la TH (p<0,001) et d’infections après la TH (p=0,006) par rapport au groupe Sarc-. La durée de l’hospitalisation était aussi prolongée chez le groupe Sarc+ comparativement au groupe Sarc- (p<0,001). Conclusion : La sarcopénie persistante ou nouvellement développée telle qu’évaluée jusqu’à 1 an après la TH est associée à un mauvais pronostic, particulièrement en période post-TH. La mise en place de stratégies d’intervention pour préserver ou même augmenter la masse musculaire pourrait aider à améliorer le pronostic des patients suite à la TH.

Introduction: Sarcopenia affects up to 70% of patients suffering from chronic liver disease (cirrhosis). The presence of sarcopenia may influence the prognosis of cirrhotic patients before and after liver transplantation (LT). Few studies have assessed the evolution of sarcopenia in LT. The goal of this study was to follow the evolution and assess the impact of sarcopenia on the prognosis of cirrhotic patients before and after LT. Methods: Skeletal muscle index (SMI) was calculated from cross‐sectional muscle area at the third lumbar level (L3) on computed tomography (CT). The following CT‐scans were analysed: before LT + before discharge and/or nearest 1‐year post‐LT. Sarcopenia was defined using previously published cutoffs based on gender. The association of sarcopenia with prognostic factors (mortality, hospital stay, infections, readmissions) was assessed in cirrhotic patients who underwent LT. Results: Thus far, the average SMI before LT of sarcopenic and non‐sarcopenic patients were 40.3±5.3 cm2/m2 and 58.7±13.7 cm2/m2, respectively. The correlation of SMI with length of hospital stay, infections, and readmissions were high (rspearman = −0.714 p = 0.071), moderate (rspearman = −0.598 p = 0.156), and low (rspearman = −0.386 p = 0.393). Conclusions: Preliminary results indicate that low muscle mass before LT tends to be associated with prolonged hospitalization. As we analyse the remaining data, the strength of the relationship between sarcopenia and the prognosis in LT will help better guide patient care.

Problématique: La sarcopénie (perte de masse et de fonction musculaires) affecte 30 à 70% des patients atteints de maladie hépatique chronique (cirrhose). Un Canadien sur 4 souffrirait de maladie hépatique. Chez les patients cirrhotiques, la présence de la sarcopénie avant et après la transplantation hépatique (TH) serait associée à un mauvais pronostic. Objectif : Le but général de cette étude rétrospective en cours est de déterminer, chez les patients cirrhotiques, la prévalence de la sarcopénie avant la TH ainsi que son impact sur le pronostic après la TH. Méthodologie : Notre étude vise l’inclusion de 100 patients cirrhotiques de diverses étiologies. L’évaluation de la masse musculaire avant la TH s’effectue en utilisant l’index musculaire squelettique lequel est basé sur l’analyse de l’examen radiologique de tomodensitométrie (CT-scan) au niveau de la 3e vertèbre lombaire. La durée de l’hospitalisation, la fréquence d’infections et le nombre de réadmissions durant la première année post-TH sont également recueillis par la consultation des dossiers médicaux. Résultats attendus: Nous anticipons que la sarcopénie soit répandue chez les patients cirrhotiques à l’étude. Sa présence pourrait être associée à une durée d’hospitalisation prolongée, à de fréquentes infections et à des réadmissions récurrentes. Discussion : Une prise en charge de la sarcopénie pourrait s’avérer primordiale si sa présence influence le pronostic des patients suite à la TH.
