RÉSUMÉ
BACKGROUND & AIMS: Treatment outcomes for people living with autoimmune hepatitis (AIH) are limited by a lack of specific therapies, as well as limited well-validated prognostic tools and clinical trial endpoints. We sought to identify predictors of outcome for people living with AIH. METHODS: We evaluated the clinical course of people with AIH across 11 Canadian centres. Biochemical changes were analysed using linear mixed-effect and logistic regression. Clinical outcome was dynamically modelled using time-varying Cox proportional hazard modelling and landmark analysis. RESULTS: In 691 patients (median age 49 years, 75.4% female), with a median follow-up of 6 years (25th-75th percentile, 2.5-11), 118 clinical events occurred. Alanine aminotransferase (ALT) normalisation occurred in 63.8% of the cohort by 12 months. Older age at diagnosis (odd ratio [OR] 1.19, 95% CI 1.06-1.35) and female sex (OR 1.94, 95% CI 1.18-3.19) were associated with ALT normalisation at 6 months, whilst baseline cirrhosis status was associated with reduced chance of normalisation at 12 months (OR 0.52, 95% CI 0.33-0.82). Baseline total bilirubin, aminotransferases, and IgG values, as well as initial prednisone dose, did not predict average ALT reduction. At baseline, older age (hazard ratio [HR] 1.25, 95% CI 1.12-1.40), cirrhosis at diagnosis (HR 3.67, 95% CI 2.48-5.43), and elevated baseline total bilirubin (HR 1.36, 95% CI 1.17-1.58) increased the risk of clinical events. Prolonged elevations in ALT (HR 1.07, 95% CI 1.00-1.13) and aspartate aminotransferase (HR 1.13, 95% CI 1.06-1.21), but not IgG (HR 1.01, 95% CI 0.95-1.07), were associated with higher risk of clinical events. Higher ALT at 6 months was associated with worse clinical event-free survival. CONCLUSION: In people living with AIH, sustained elevated aminotransferase values, but not IgG, are associated with poorer long-term outcomes. Biochemical response and long-term survival are not associated with starting prednisone dose. IMPACT AND IMPLICATIONS: Using clinical data from multiple Canadian liver clinics treating autoimmune hepatitis (AIH), we evaluate treatment response and clinical outcomes. For the first time, we apply mixed-effect and time-varying survival statistical methods to rigorously examine treatment response and the impact of fluctuating liver biochemistry on clinical event-free survival. Key to the study impact, our data is 'real-world', represents a diverse population across Canada, and uses continuous measurements over follow-up. Our results challenge the role of IgG as a marker of treatment response and if normalisation of IgG should remain an important part of the definition of biochemical remission. Our analysis further highlights that baseline markers of disease severity may not prognosticate early treatment response. Additionally, the initial prednisone dose may be less relevant for achieving aminotransferase normalisation. This is important for patients and treating clinicians given the relevance and importance of side effects.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) can be an effective treatment for cirrhotic patients who develop variceal bleeding and ascites. However, TIPS placement is associated with an increased risk of developing hepatic encephalopathy (HE). Recently, there have been efforts to use the typical medical therapies prophylactically in patients undergoing TIPS placement to prevent post-TIPS HE. METHODS: We conducted literature searches in MEDLINE, Embase, CINAHL, Scopus, and Cochrane to examine studies that use prophylactic medical therapy for preventing post-TIPS HE. A narrative synthesis and grading of recommendations assessment assessment were done for all studies. Meta-analysis was performed for eligible studies using the Mantel-Haenszel method random-effects model. Nine hundred twenty-one articles were screened and 5 studies were included in the study after 2 levels of screening. The medications studied were rifaximin, lactulose, lactitol, L-Ornithine-L-aspartate (LOLA), albumin, and combination therapies. RESULTS: Narrative results showed that lactulose, lactitol, LOLA and albumin prophylaxis were not associated with reduction in HE occurrence or mortality. A combination of rifaximin and lactulose was found to be associated with lower occurrence of HE, and the results were not different when LOLA was added. Meta-analysis (n = 3) showed that rifaximin treatment was not associated with changes in HE occurrences. CONCLUSION: In conclusion, a vast majority of medications were not found to be effective post-TIPS HE prophylaxis when used alone. A rifaximin and lactulose combination therapy may be beneficial. Overall, there is significant limitation in the current data and more studies are needed to yield more robust meta-analysis results in the future.

Length of stay (LOS) is a significant contributor to overall patient outcomes for patients undergoing liver transplantation. This study documents a quality improvement project aiming to reduce the median post-transplant LOS for liver transplant patients. We instituted five Plan-Do-Study-Act cycles with the goal of reducing LOS by 3 days from a baseline median of 18.4 days over 1 year. Balancing measures such as readmission rates ensured any decrease in stay was not associated with significantly increased patient complications. Over the 28-month intervention period and 24-month follow-up period, there were 193 patients discharged from hospital with a median LOS of 9 days. The changes appreciated during quality improvement interventions carried over to sustained improvements, with no significant variability in LOS postintervention. Discharge within 10 days increased from 18.4% to 60% over the study period, with intensive care unit stay decreasing from a median of 3.4-1.9 days. Thus, the development of a multidisciplinary care pathway, with patient engagement, led to improved and sustained discharge rates with no significant differences in readmission rates.

Importance: Trainees routinely participate in colonoscopy procedures, yet whether their involvement is positively or negatively associated with procedural quality is unknown because prior studies involved small number of trainees and/or supervisors, lacked generalizability, and/or failed to adjust for potential confounders. Objective: To assess the association between trainee participation and colonoscopy quality metrics. Design, Setting, and Participants: This multicenter population-based cohort study was conducted at 21 academic and community hospitals between April 1, 2017, and October 31, 2018, among consecutive adult patients undergoing colonoscopy. Procedures performed by endoscopists who did not supervise trainees were excluded. Statistical analysis was performed from April 3, 2017, to October 31, 2018. Exposure: Participation by a trainee, defined as a resident or fellow enrolled in a gastroenterology or general surgery training program. Main Outcomes and Measures: The primary outcome was the adenoma detection rate (ADR), and secondary outcomes were sessile serrated polyp detection rate (ssPDR), polyp detection rate (PDR), cecal intubation rate (CIR), and perforation rate. Results: A total of 35â¯499 colonoscopies (18â¯989 women [53.5%]; mean [SD] patient age, 60.0 [14.1] years) were performed by 71 physicians (mean [SD] time in practice, 14.0 [9.3] years); 5941 colonoscopies (16.7%) involved trainees. There were no significant differences in the ADR (26.4% vs 27.3%; P = .19), CIR (96.7% vs 97.2%; P = .07), and perforation rate (0.05% vs 0.06%; P = .82) when trainees participated vs when they did not participate, whereas the the ssPDR (4.4% vs 5.2%; P = .009) and PDR (39.2% vs 42.0%; P < .001) were significantly lower when trainees participated vs when they did not. After adjustment for potential confounders, the ADR (risk ratio [RR], 0.97; 95% CI, 0.91-1.03; P = .30), PDR (RR, 0.98; 95% CI, 0.93-1.04; P = .47), and CIR (RR, 0.93; 95% CI, 0.78-1.10; P = .38) were not associated with trainee participation, although the ssPDR remained significantly lower (RR, 0.79; 95% CI, 0.64-0.98; P = .03). Conclusions and Relevance: This study suggests that trainee involvement during colonoscopy was associated with reduced ssPDR but not other colonoscopy outcome measures. Extra care should be exercised when examining the right colon when trainees are involved.

Cirrhosis is a multisystemic condition in which pregnancy is uncommon; however, the combination may lead to a higher incidence of spontaneous fetal loss and complications such as progressive jaundice, ascites and variceal bleeding. Here we present a 21-year-old woman who presented at 14 weeks' gestation with new jaundice and a two-month history of melena consistent with pre-existing cirrhosis of unclear aetiology. She delivered a healthy male infant at 34 weeks and five days of gestation vaginally with good haemostasis. In the literature, maternal mortality rates have been reported in up to 61% of these women, however, this risk is likely lower now with modern endoscopic therapies and improved access to blood products. There is limited information about labour and delivery in cirrhosis, although the best outcomes to date have been described in well-compensated women.

BACKGROUND AND AIMS: We investigated associations between ethnicity, survival, and disease severity in a diverse Canadian cohort of patients with primary biliary cholangitis (PBC). APPROACH AND RESULTS: Patients with PBC were included from the Canadian Network for Autoimmune Liver Disease. Ethnicity was defined using a modified list adopted from Statistics Canada, and ethnicities with small samples were grouped. Clinical events were defined as liver decompensation, HCC, liver transplantation, or death. Clinical event-free and liver transplantation-free survival were analyzed using Cox regression. Trajectories of serum liver function tests were assessed over time using mixed-effects regression. Health-related quality of life was assessed using the Short Form 36, the PBC-40 questionnaire, and the 5-D Itch scale and analyzed using mixed-effects regression. The cohort included 1538 patients with PBC from six sites and was comprised of 82% White, 4.7% Indigenous, 5.5% East Asian, 2.6% South Asian, and 5.1% miscellaneous ethnicities. Indigenous patients were the only ethnic group with impaired liver transplant-free and event-free survival compared to White patients (HR, 3.66; 95% CI, 2.23-6.01; HR, 3.09; 95% CI, 1.94-4.92). Indigenous patients were more likely to have a clinical event before diagnosis (10%) than all other ethnic groups despite similar age at diagnosis. Indigenous patients presented with higher alkaline phosphatase, total bilirubin, and GLOBE scores than White patients; and these relative elevations persisted during follow-up. CONCLUSIONS: Indigenous Canadians with PBC present with advanced disease and have worse long-term outcomes compared to White patients.

BACKGROUND: Transplantation offers the best survival for patients with end stage organ disease. Transplant of hepatitis C virus (HCV) nucleic acid test (NAT) positive organs into negative recipients is a novel strategy that can expand the donor pool. We aim to evaluate our centre's experience. METHODS: We preformed a retrospective review of anti-HCV NAT positive and negative organs into negative recipients transplanted over 27 months. Primary outcome was the success rate of eradication of HCV post-transplant. Secondary outcomes were rate of transmission of HCV, treatment adverse events, and graft failure. RESULTS: 33 anti-HCV positive organs were transplanted into negative recipients. 22 (66.7%) were NAT positive. Median recipients age was 49 years (interquartile range [IQR] 44.5-62.0) with the majority being males (57.6%). NAT positive organ transplantations included 16 kidneys, 3 livers, 1 kidney-pancreas, 1 liver-kidney, and 1 heart. The most common HCV genotype was 1a (59.1%). The median time to initiating therapy was 41.5 days. SVR12 was 100% in patients who finished therapy. There were no adverse events with therapy and no graft failure. CONCLUSIONS: Anti-HCV NAT positive organ transplantation into negative recipients is safe with excellent eradication rates and no significant adverse events or graft failure. This would expand donor pool to close the gap between supply and demand.

BACKGROUND: IgG4-related disease involvement of the digestive tract is very rare. In few reported cases of isolated gastric/duodenal IgG4-related disease, none of which resulted in luminal obstruction. CASE PRESENTATION: A 59 years old female presented with longstanding gastrointestinal symptoms. CT showed mural thickening of the proximal duodenum. Gastroscopy showed antral ulcer extending into the duodenum with outlet obstruction and biopsy showed acute on chronic duodenitis. Whipple's procedure was performed and IgG4-related disease was diagnosed on final pathology. Symptoms were revolved on mycophenolate mofetil and prednisone with no recurrence. CONCLUSIONS: Our case is the only reported case with gastric outlet obstruction secondary to gastroduodenal IgG4-related disease. The diagnosis should be considered in the differential diagnosis of unexplained duodenal stricture, gastric outlet obstruction or gastrointestinal ulceration. IgG4-related disease usually responds to steroids but long-term response rates to steroid-sparing agents, especially in the subset of patients with luminal IgG4-related disease remains to be determined.

BACKGROUND: Recurrence of hepatocellular carcinoma (HCC) after liver transplantation is a major cause of morbidity and mortality. To date, there is no widely accepted pathologic assessment tool to predict HCC recurrence. In 2007, we developed a pathologic risk score that stratified patients into low, intermediate, or high risk for recurrence based on explant pathology. The aim of this study was to externally validate this risk score. METHODS: We retrospectively evaluated 124 patients over a 10-year period who underwent liver transplantation for HCC. Using explanted pathology reports, each patient was stratified according to the pathologic risk score and followed over time for HCC recurrence. RESULTS: Recurrence occurred in 15 patients (12%) after a mean follow-up of 25 months. Using the pathologic risk score, 10 (8%), 21 (17%), and 93 (75%) patients were stratified into high, intermediate, and low risk of recurrence, respectively. Among these risk groups, recurrence occurred in 50%, 28.5%, and 4.3% (P < .01) of patients, respectively. Using the optimal cutoff value ≤3.5, our risk score had a sensitivity of 80% and specificity of 79% with an area under the receiver operator characteristic curve of 0.8. Those with lower risk scores had higher recurrence-free survival (P < .0001). CONCLUSIONS: Our pathologic risk score accurately risks stratified patients for HCC recurrence after liver transplant. It can be used to tailor surveillance strategies for those deemed to be at elevated risk for recurrence.

BACKGROUND: Liver transplantation (LT) remains the curative treatment for symptomatic Polycystic Liver Disease (PCLD) patients and is associated with excellent survival rates. The aim of the study is to review the Ontario experience in LT for PCLD. METHODS: A retrospective study was performed from pre-existing LT databases from the LT Units at Toronto General Hospital and London Health Sciences Center, which are the two LT programs in Ontario, Canada. This database contains demographic, clinical parameters and follow-up of all patients transplanted for PCLD. Data was extracted for patients who underwent LT between January 2000-April 2017 and included follow up until December 31st, 2018. RESULTS: A total of 3560 patients underwent LT, of whom 51 (1.4%) had PCLD and met inclusion criteria. 43 (84%) of these patients were female. The median physiologic Model for End Stage Liver Disease (MELD-Na) score at time of referral was 13 (IQR = 7-22), however all patients required MELD-Na exception points to receive LT. The median age of transplant was 62 years (IQR = 59-64) for male vs. 52 (IQR = 45-56) for female patients. 33 (65%) of our cohort had PCLD while 9 (17.5%) had ADPKD and 9 (17.5%) had both diseases. 39 (76%) had LT due to symptoms of mass effect, while 8 (16%) had portal hypertensive complications. After a median follow-up of 6.3 (IQR = 2.9-12.5) years, the probability of survival was 96% (95% CI: 90%, 100%). Log-rank test, comparing survival analysis between males and females did not show a statistically significant difference (p = 0.26). CONCLUSION: Most patients underwent LT for PCLD due to symptoms of mass effect with women being more likely than men to undergo LT. LT for PCLD had excellent long-term survival.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) is an obesity-related disorder that is rapidly increasing in incidence and is considered the hepatic manifestation of the metabolic syndrome. The gut microbiome plays a role in metabolism and maintaining gut barrier integrity. Studies have found differences in the microbiota between NAFLD and healthy patients and increased intestinal permeability in patients with NAFLD. Fecal microbiota transplantation (FMT) can be used to alter the gut microbiome. It was hypothesized that an FMT from a thin and healthy donor given to patients with NAFLD would improve insulin resistance (IR), hepatic proton density fat fraction (PDFF), and intestinal permeability. METHODS: Twenty-one patients with NAFLD were recruited and randomized in a ratio of 3:1 to either an allogenic (n = 15) or an autologous (n = 6) FMT delivered by using an endoscope to the distal duodenum. IR was calculated by HOMA-IR, hepatic PDFF was measured by MRI, and intestinal permeability was tested using the lactulose:mannitol urine test. Additional markers of metabolic syndrome and the gut microbiota were examined. Patient visits occurred at baseline, 2, 6 weeks, and 6 months post-FMT. RESULTS: There were no significant changes in HOMA-IR or hepatic PDFF in patients who received the allogenic or autologous FMT. Allogenic FMT patients with elevated small intestinal permeability (>0.025 lactulose:mannitol, n = 7) at baseline had a significant reduction 6 weeks after allogenic FMT. DISCUSSION: FMT did not improve IR as measured by HOMA-IR or hepatic PDFF but did have the potential to reduce small intestinal permeability in patients with NAFLD.

BACKGROUND: Patients with inflammatory bowel disease (IBD) post-liver transplant (LT) may have bowel inflammation requiring biologic therapy. We aimed to evaluate the safety of combination biologic and antirejection therapy in IBD patients after LT from a tertiary center case series and an updated literature review. METHODS: Inflammatory bowel disease patients undergoing LT between 1985 and 2018 and requiring combination biologic and antirejection therapy post-LT were identified from the London Health Sciences Transplant Registry (Ontario, Canada). Safety outcomes were extracted by medical chart review. For an updated literature review, EMBASE, Medline, and CENTRAL were searched to identify studies evaluating the safety of combination biologic and antirejection therapy in IBD patients. RESULTS: In the case series, 19 patients were identified. Most underwent LT for primary sclerosing cholangitis (PSC; 14/19, 74%) treated with anti-integrins (8/19, 42%) or tumor necrosis factor α (TNF) antagonists (6/19, 32%). Infections occurred in 11/19 (58%) patients, most commonly Clostridium difficile (4/19, 21%). Two patients required colectomy, and 1 patient required re-transplantation. In the literature review, 13 case series and 8 case reports reporting outcomes for 122 IBD patients treated with biologic and antirejection therapy post-LT were included. PSC was the indication for LT in 97/122 (80%) patients, and 91/122 (75%) patients were treated with TNF antagonists. Infections occurred in 32/122 (26%) patients, primarily Clostridium difficile (7/122, 6%). CONCLUSIONS: Inflammatory bowel disease patients receiving combination biologic and antirejection therapy post-LT appeared to be at increased risk of Clostridium difficile. Compared with the general liver transplant population in the published literature, there was no increased risk of serious infection.

Autoimmune hepatitis is an infrequent but significant side effect of infliximab treatment. Diagnosis of autoimmune hepatitis is based on clinical, laboratory, and histological findings. Initial treatment involves cessation of infliximab and trial of prednisone. We present a rare case of infliximab-induced autoimmune hepatitis leading to liver failure requiring transplantation.
RÉSUMÉ
BACKGROUND AND AIMS: Frailty is associated with increased morbidity and mortality, and this is tightly linked to liver decompensation and increased complication rates among liver transplant (LT) candidates. The aim of the study was to evaluate the efficacy of a structured in- and outpatient exercise training program for cirrhotic patients who were referred for liver transplant evaluation. METHODS: We retrospectively reviewed 458 consecutive LT patients. There were 200 patients who underwent LT prior to the implementation of an exercise training program (non-ETP) and 258 LT patients who underwent a comprehensive exercise training program (ETP). Baseline characteristics, readmission rate, and length of hospital stay (LOS) were analyzed and compared between the 2 groups. RESULTS: The ETP group were more likely to have diabetes mellitus and coronary artery disease. However, there was no significant difference in the postoperative complication rates between the 2 groups except for more infections in the ETP group compared to the non-ETP group. There was a trend toward lower 90-day readmission rate in the ETP group (17.9% vs 20%) and shorter LOS (14 vs 17 days). CONCLUSION: There was a trend toward reduced 90-day readmission and shorter length of stay after implementation of an exercise training program.

Immunosuppressive therapies are indicated following liver transplantation (LT) to prevent graft loss through rejection, and these same agents also may have a role in the management of inflammatory bowel disease (IBD). The aims of this study were to examine the effects of immunosuppression following LT on IBD activity and to identify markers of IBD control post-LT in patients with IBD who underwent LT for primary sclerosing cholangitis (PSC). A retrospective analysis of all adult patients with a pre-LT diagnosis of IBD who underwent LT for PSC over a 15-year period was performed. The primary outcome was IBD activity based on symptomatology and endoscopic assessment. Secondary outcomes included recipient mortality and post-LT development of colorectal cancer or small bowel lymphoma. A total of 105 patients underwent LT for PSC, and IBD was diagnosed in 27 (26%) pre-LT. Patients were followed for a mean of 88.5 months. Fourteen (52%) patients had stable IBD, 6 (22%) had worsening disease, and 7 (26%) had clinical improvement after LT. Colorectal cancer developed in 2 (7%) patients, and small bowel lymphoma developed in 1 (4%) patient. The absence of additional maintenance therapy for IBD was found to be associated with good outcome for IBD control. The use of either infliximab (Remicade, Janssen Biotech) or corticosteroids to control IBD post-LT was associated with poor outcome. Most patients with PSC and IBD had a stable course of IBD post-LT. The need for infliximab or additional or prolonged corticosteroids after LT appears to be a surrogate marker of aggressive disease.
RÉSUMÉ
Sirolimus is an approved anti-rejection agent following liver or kidney transplantation that works through inhibition of the mammalian target of rapamycin (mTOR). As sirolimus functions through a pathway independent of calcineurin inhibition, it may have less potential for nephrotoxicity and carcinogenesis. That being said, there are a myriad of potential adverse effects reported with sirolimus, many of which are severe and unknown or poorly understood. Herein we present a case of sirolimus causing a serious but uncommon adverse event in an adult liver transplant recipient; the adverse event in this instance unfortunately resulted in significant medical testing and morbidity. The adverse event profile of sirolimus is summarized through review of available evidence.

We report a 65-year-old lady who presented with rapidly progressive dementia and was found to have Creutzfeldt-Jacob disease (CJD). On reviewing the literature, there have been only 3 case reports of CJD from Saudi Arabia. Our aim is to report this rare disease and to include it in the differential diagnosis of rapidly progressive dementia in our practice.
