Liver Transplant Recipients Speak Out on Public Awareness and Education Surrounding Alcohol-Related Health Effects: A Survey Study.

BACKGROUND: Compared to other recreational substances in Canada, alcohol consumption incurs the highest healthcare costs. Liver transplant recipients are unique stakeholders as members of the general public with lived experiences of liver disease. We sought to explore their perspectives on the current state of public education on alcohol-related health effects. METHODS: The most recent 400 liver transplant recipients at Vancouver General Hospital, Canada, were invited to participate in an anonymous online survey on alcohol-related health effects by mail, email, and phone. RESULTS: Of 372 contacted patients, 212 (57%) completed the survey. Most patients were between 60-79 years, 63% were male, and 69% were Caucasian. The most common liver conditions leading to transplant were viral hepatitis (33%), alcohol-related liver disease (16%), autoimmune liver disease (14%), and non-alcoholic fatty liver disease (15%). Most patients knew that alcohol leads to liver failure (85%), but fewer knew about alcohol leading to cancer (54%), heart disease (50%), and damage to other organs (58%). Most common sources of information included public media (61%), family and friends (52%), and physicians (49%), with narrative comments about learning of alcohol-related health effects after liver diagnosis. Most patients believed that public health education at a middle/high school level would have long-term efficacy (72%) compared to health warning labels (33%) and safety messaging in commercials (39%). Current public education was felt to be adequate by only 20% of patients and 73% of patients supported health warning labels. CONCLUSIONS: Liver transplant patients reported a high, but not universal, awareness of alcohol-related health effects. A majority thought that current public health efforts were inadequate; it is critical to implement public health interventions to ensure consumers are able to make an informed decision on alcohol consumption.

Post-traumatic Stress Disorder in Resident Physicians.

Background Research suggests that symptoms of post-traumatic stress disorder (PTSD) may be common in physicians who have experienced a traumatic event, but it is unclear if medical residents suffer from similar symptoms. Objective To determine the prevalence of PTSD symptoms in the resident physician population of the University of British Columbia based on the new Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5) criteria. Method A link to an online questionnaire containing 27 questions, including residency training and year, as well as the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-fifth edition (PCL-5) was e-mailed and completed by the resident physicians of the University of British Columbia. Results Forty-three residents completed the survey and 38 had complete data. Mean PCL-5 score was 10.3 for the 38 subjects. Differences between PCL-5 score and resident year yielded the following: postgraduate year (PGY)-1=8.6; PGY-2=16.5; PGY-3=3.6; PGY-4=4.0; PGY-5=7.7. With respect to the type of traumatic event and PCL-5 score, the following was observed: Death=5.3, Violence=13.8, Medical Error=8.0, Bullying=38.0, None=45.0. The Kruskal-Wallis test showed no statistically significant differences in total PCL-5 score for PGY or type of traumatic event. Regardless of post-graduate year or trauma experience, four subjects out of 38 (10.5%) had a total PCL-5 score of 33 or greater, while one subject (2.5%) had a score greater than 50. Conclusion The results from this study conclude that resident physicians do suffer from PTSD symptoms at a rate higher than the average American population. As PTSD symptoms can often be very distressing and potentially affect work ethic negatively, further studies are indicated to better understand these symptoms and hopefully lead to better care in treating PTSD symptoms in resident physicians.

Transplantation of a Liver Allograft From a Hepatitis C Virus Seropositive Donor With Previous Sustained Virologic Response to an Uninfected Recipient Suffering Steroid Refractory Acute Graft Rejection With No Evidence of HCV Transmission.

BACKGROUND: The goal of treating chronic hepatitis C virus (HCV) infection is sustained virologic response (SVR). There is concern that despite achieving SVR, replication-competent HCV may be sequestered at low levels within the liver and could theoretically reactivate with immunosuppression. We report transplantation of a HCV-seropositive liver donor, who achieved SVR, into a seronegative patient without HCV reactivation despite profound immunosuppression. METHOD: Retrospective chart review. RESULTS: We present a 21-year-old male who was HCV seronegative and received a liver transplant from a donor who had been treated for HCV and achieved SVR. The liver recipient, despite developing severe acute graft rejection and undergoing intense immunosuppression with T cell-depleting antibodies, did not become HCV RNA-positive with a follow up period of 8 months. The recipient was HCV seronegative before transplant, but became HCV seropositive immediately posttransplant. The antibodies were undetectable after 97 days, in keeping with a passive antibody transmission or B lymphocyte transmission with the graft. CONCLUSIONS: To the best of our knowledge, this is the first reported case of an HCV seropositive liver allograft transplanted into an HCV-negative recipient who subsequently received intense immunosuppression. This case, therefore, is an encouraging and novel step in liver transplantation, and demonstrates that SVR may be closer to a true "cure" of HCV in the donor population and that, even in circumstances of very potent immunosuppression in the recipient, this SVR is sustained.

Response to Sildenafil in a Patient With Coexisting Post-Liver Transplant Portopulmonary Hypertension and Hepatopulmonary Syndrome.

Hepatopulmonary syndrome and portopulmonary hypertension are complications of portal hypertension with opposing mechanisms that can coexist. Moderate portopulmonary hypertension, which is a contraindication to a liver transplant, must be managed with pulmonary vasodilators to normalize pulmonary arterial pressures before a transplant listing. Concomitant hepatopulmonary syndrome complicates the management of portopulmonary hypertension, as pulmonary vasodilators can theoretically exacerbate the intrapulmonary dilatation believed to cause hepatopulmonary syndrome. We describe a case of a post-liver transplant patient with concomitant hepatopulmonary syndrome and portopulmonary hypertension safely treated with sildenafil.

Use of Monitoring Gamma-Glutamyl Transpeptidase Levels After Liver Transplant: A Longitudinal Retrospective Analysis of a Single-Center's Experience.

OBJECTIVES: Recently, gamma-glutamyl transpeptidase has garnered increased attention as a diagnostic tool in the early identification of liver disease. However, its value in liver transplant is largely unknown, as the disease processes leading to abnormal gamma-glutamyl transpeptidase levels and the expected temporal trends in gamma-glutamyl transpeptidase levels during the period after liver transplant remain unclear. MATERIALS AND METHODS: Between January 2010 and August 2013, consecutive patients who underwent liver transplant at Vancouver General Hospital (Vancouver, Canada) were assessed longitudinally up to 1 year after liver transplant. A "gamma-glutamyl transpeptidase event" was defined as 2 abnormal gamma-glutamyl transpeptidase values (exceeding sex-specific limits of normal, at 55 U/L for female and 80 U/L for male patients) ≥ 1 week apart. RESULTS: Our study included 147 liver transplant recipients. The median gamma-glutamyl transpeptidase level on day 1 after liver transplant was 73 U/L, which peaked to 435 U/L during the first month after liver transplant and returned to within normal parameters by 1 year. In total, there were 282 gamma-glutamyl transpeptidase events, with biliary complications (22%), acute rejection (16%), and hepatitis C virus recurrence (10%) being the most common causes. In 39% of events, no cause was identified. When attempting to identify a disease-associated event, if gamma-glutamyl transpeptidase was the initial liver biochemistry test to double in value, it had 42% sensitivity and 40% specificity. Comparatively, if gamma-glutamyl transpeptidase was the initial liver biochemistry test to become abnormal, it had 3% sensitivity and 93% specificity. CONCLUSIONS: Although gamma-glutamyl transpeptidase almost universally becomes abnormal after liver transplant, a specific pathologic cause was not commonly identified. Interpreting the characteristics of gamma-glutamyl transpeptidase elevation has limited use for identifying the underlying reason for its elevation.

Hepatitis C (chronic).

INTRODUCTION: About 60% to 85% of people infected with hepatitis C virus will go on to develop chronic hepatitis C, which is now believed to affect 3% of the world's population. METHODS AND OUTCOMES: We conducted a systematic overview and aimed to answer the following clinical questions: What are the effects of interferon-free treatments in treatment-naïve people with chronic hepatitis C infection without cirrhosis? What are the effects of interferon-free treatments in treatment-naïve people with chronic hepatitis C infection with cirrhosis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this review). RESULTS: After deduplication and removal of conference abstracts, 30 records were screened for inclusion in the review. Appraisal of titles and abstracts led to the exclusion of 11 studies and the further review of 19 full publications. Of the 19 full articles evaluated, two systematic reviews and one RCT were added. We performed a GRADE evaluation for two PICO combinations. CONCLUSIONS: In this systematic overview, we categorised the efficacy for 12 different intervention/comparison combinations, based on information relating to the effectiveness and safety of sofosbuvir (with or without ribavirin), sofosbuvir (with or without ribavirin) plus ledipasvir, and sofosbuvir (with or without ribavirin) plus simeprevir, all in people with and without cirrhosis.

Patient preference and willingness to pay for transient elastography versus liver biopsy: A perspective from British Columbia.

BACKGROUND: The cost of liver biopsy (LB) is publicly funded in British Columbia, while the cost of transient elastography (FibroScan [FS], Echosens, France) is not. Consequently, there is regional variation regarding FS access and monitoring of liver disease progression. OBJECTIVE: To evaluate patient preference for FS versus LB and to assess the willingness to self-pay for FS. METHODS: Questionnaires were distributed in clinic and via mail to LB-experienced and LB-naive patients who underwent FS at Vancouver General Hospital, Vancouver, British Columbia. RESULTS: The overall response rate was 76%. Of the 422 respondents, 205 were LB-experienced. The mean age was 53.5 years, 50.2% were male, 54.7% were Caucasian, 38.2% had hepatitis C and 26.3% had an annual household income >$75,000. Overall, 95.4% of patients preferred FS to LB. FS was associated with greater comfort than LB, with the majority reporting no discomfort during FS (84.1% versus 7.8% for LB), no discomfort after (96.2% versus 14.6% LB) and no feelings of anxiety after FS explanation (78.2% versus 12.7% LB). FS was also associated with greater speed, with the majority reporting short test duration (97.2% versus 48.3% LB) and short wait for the test result (95.5% versus 30.2% LB). Most (75.3%) respondents were willing to self-pay for FS, with 26.3% willing to pay $25 to $49. Patients with unknown liver disease preferred LB (OR [FS preference] 0.20 [95% CI 0.07 to 0.53]). CONCLUSIONS: FS was the preferred method of assessing liver fibrosis among patients, with the majority willing to self-pay. To ensure consistency in access, provincial funding for FS is needed. However, LB remains the procedure of choice for individuals with an unknown diagnosis.

Antimitochondrial antibody serocoversion post-liver transplant during hepatitis C treatment with peginterferon α, ribavirin and telaprevir.

Pegylated interferon alpha (PEG-IFN α), a key component of chronic hepatitis C therapy, has been linked to the development of auto-antibodies and autoimmune disease. We report the first case of antimitochondrial antibody (AMA) seroconversion during PEG-INF α based therapy after liver.1-4 transplantation. A fiftyseven year-old man five months after liver transplantation was initiated on hepatitis C triple therapy with PEG-INF α, ribavirin and telaprevir. He had failed previous PEG-IFN α and ribavirin 12 years pre-transplant and his AMA remained negative pre-transplant. After twelve weeks of antiviral therapy, he developed elevated liver enzyme tests associated with an AMA seroconversion to seropositivity. A liver biopsy failed to show histological evidence of primary biliary cirrhosis or graft rejection. He was initiated on urseodeoxycholic acid with subsequent improvement of his liver enzymes. This case demonstrates that despite adequate immunosuppression, AMA seroconversion may occur post-transplant during interferon-based therapy. As AMA seroconversion did not occur during the pre-transplant PEG-IFN therapy, we speculate that donor allograft antigens in combination with PEG-IFN may have been a factor in the post-transplant seroconversion.

Rates of minor adverse events and health resource utilization postcolonoscopy.

BACKGROUND: Little is known about minor adverse events (MAEs) following outpatient colonoscopies and associated health care resource utilization. OBJECTIVE: To estimate the rates of incident MAE at two, 14 and 30 days postcolonoscopy, and associated health care resource utilization. A secondary aim was to identify factors associated with cumulative 30-day MAE incidence. METHODS: A longitudinal cohort study was conducted among individuals undergoing an outpatient colonoscopy at the Montreal General Hospital (Montreal, Quebec). Before colonoscopy, consecutive individuals were enrolled and interviewed to obtain data regarding age, sex, comorbidities, use of antiplatelets/anticoagulants and previous symptoms. Endoscopy reports were reviewed for intracolonoscopy procedures (biopsy, polypectomy). Telephone or Internet follow-up was used to obtain data regarding MAEs (abdominal pain, bloating, diarrhea, constipation, nausea, vomiting, blood in the stools, rectal or anal pain, headaches, other) and health resource use (visits to emergency department, primary care doctor, gastroenterologist; consults with nurse, pharmacist or telephone hotline). Rates of incident MAEs and health resources utilization were estimated using Bayesian hierarchical modelling to account for patient clustering within physician practices. RESULTS: Of the 705 individuals approached, 420 (59.6%) were enrolled. Incident MAE rates at the two-, 14- and 30-day follow-ups were 17.3% (95% credible interval [CrI] 8.1% to 30%), 10.5% (95% CrI 2.9% to 23.7%) and 3.2% (95% CrI 0.01% to 19.8%), respectively. The 30-day rate of health resources utilization was 1.7%, with 0.95% of participants seeking the services of a physician. No predictors of the cumulative 30-day incidence of MAEs were identified. DISCUSSION: The incidence of MAEs was highest in the 48 h following colonoscopy and uncommon after two weeks, supporting the Canadian Association of Gastroenterology's recommendation for assessment of late complications at 14 days. Predictors of new onset of MAEs were not identified, but wide CrIs did not rule out possible associations. Although <1% of participants reported consulting a physician for MAEs, this figure may represent a substantial number of visits given the increasing number of colonoscopies performed annually. CONCLUSION: Postcolonoscopy MAEs are common, occur mainly in the first two weeks postcolonoscopy and result in little use of health resources.
