End stage liver disease etiology & transplantation referral outcomes of major ethnic groups in British Columbia, Canada: A cohort study.

Liver disease etiology and transplantation outcomes may vary by ethnicity. We aimed to determine if disparities exist in our province.We reviewed the provincial database for liver transplant referrals.

Three-Dimensional Multi-Frequency Shear Wave Absolute Vibro-Elastography (3D S-WAVE) With a Matrix Array Transducer: Implementation and Preliminary In Vivo Study of the Liver.

Magnetic resonance elastography (MRE) is commonly regarded as the imaging-based gold-standard for liver fibrosis staging, comparable to biopsy. While ultrasound-based elastography methods for liver fibrosis staging have been developed, they are confined to a 1D or a 2D region of interest and to a limited depth. 3D Shear Wave Absolute Vibro-Elastography (S-WAVE) is a steady-state, external excitation, volumetric elastography technique that is similar to MRE, but has the additional advantage of multi-frequency excitation.

Biomarkers for hepatocellular cancer.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. If diagnosed early, curative treatment options such as surgical resection, loco-regional therapies, and liver transplantation are available to patients, increasing their chances of survival and improving their quality of life. Unfortunately, most patients are diagnosed with late stage HCC where only palliative treatment is available.

Early Persistent Progressive Acute Kidney Injury and Graft Failure Post Liver Transplantation.

Background: Acute kidney injury (AKI) in the setting of liver transplantation is a common and multifaceted complication. Studies in the general population have demonstrated worse prognosis with AKI episodes that persist for a longer duration. Our primary objective was to evaluate the impact of early AKI episodes that are persistent or progressive in nature, on patient outcomes and graft survival.

In-hospital post-transplant acute hepatitis A viral (HAV) infection in a liver transplant recipient who was HAV seropositive pre-transplant.

Acute hepatitis A viral (HAV) infection is rare in the liver transplant population due to recommended pre-transplant vaccinations. We report a case of acute hepatitis A infection in a liver transplant recipient. This individual had immunity to hepatitis A with protective IgG antibodies and presented with abnormal liver biochemistry in the post-transplant in-patient setting.

Immunosuppression Practices in Liver Transplantation: A Survey of North American Centers.

Objectives: There is a clear lack of clinical evidence guiding immunosuppressive management in long-term stable liver transplant recipients. As a result, anecdotal experience suggests wide variability across transplant centers. We aimed to identify patterns of immunosuppression practices in liver transplant centers across Canada and the United States.

Interaction of Gender and Hepatitis C in Risk of Chronic Renal Failure After Liver Transplantation.

Background: Chronic renal failure (CRF) is a significant cause of morbidity and mortality in post-liver transplantation (LT) recipients. The risk factors associated with the development of renal dysfunction are not clearly elucidated.

Objectives: To examine the risk factors in the development of CRF in these patients.

Lamivudine, Entecavir, or Tenofovir Treatment of Hepatitis B Infection: Effects on Calcium, Phosphate, FGF23 and Indicators of Bone Metabolism.

Background: Patients with chronic hepatitis B virus (HBV) are often treated with nucleoside/nucleotide antiviral agents and metabolic bone toxicity is a possible concern.

Objective: To determine the relationships between fibroblast growth factor 23 (FGF23), a phosphaturic hormone, bone mineral density (BMD), and bone biochemical abnormalities in these patients.

Material And Methods: This is a cross-sectional observational study comparing HBV-infected subjects treated for at least one year with tenofovir (TDF), lamuvidine (LVD), entacavir (ETV), or not treated (CON).

Ursodeoxycholic Acid in Treatment of Non-cholestatic Liver Diseases: A Systematic Review.

To systematically evaluate the literature for evidence to support the use of bile acids in non-cholestatic liver conditions. Searches were conducted on the databases of Medline (1948-March 31, 2015), Embase (1980-March 31, 2015) and the Cochrane Central Register of Controlled Trials, and on Google and Google Scholar to identify articles describing ursodeoxycholic acid (UDCA) and its derivatives for non-cholestatic hepatic indications. Combinations of the following search terms were used: ursodeoxycholic acid, ursodiol, bile acids and/or salts, non alcoholic fatty liver, non alcoholic steatohepatitis, fatty liver, alcoholic hepatitis, alcohol, liver disease, autoimmune, autoimmune hepatitis, liver transplant, liver graft, transplant rejection, graft rejection, ischemic reperfusion injury, reperfusion injury, hepatitis B, hepatitis C, viral hepatitis, chronic hepatitis, acute hepatitis, transaminases, alanine transaminase, liver enzymes, aspartate aminotransferase, gamma-glutamyl transferase, gamma-glutamyl transpeptidase, bilirubin, alkaline phosphatase.

Successful Treatment of Hepatitis C with Simeprevir, Sofosbuvir, and Ribavirin in an HIV Coinfected Liver Transplant Patient with Advanced Chronic Kidney Disease.

Although major advances have occurred in treating patients with hepatitis C virus (HCV) with the development of new direct-acting antivirals (DAAs), treatment of liver transplant recipients with HCV, human immunodeficiency virus (HIV) coinfection, and renal disease is challenging due to the lack of efficacy and safety data in this population. We report a case of successful HCV therapy in a postliver transplant HIV coinfected patient, with stage 4 chronic kidney disease, using an all-oral regimen of simeprevir, sofosbuvir, and ribavirin. The 51-year-old male achieved SVR24, and no specific HIV-related or transplant-related adverse events were documented during the treatment period.

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.

A review of direct-acting antivirals for the treatment of hepatitis C in patients with advanced chronic kidney disease.

Historically, standard treatment of hepatitis C virus (HCV) infection in patients with renal impairment has been limited by low cure rates and poor tolerability. The introduction of direct-acting antivirals (DAAs) has revolutionized the treatment of HCV with impressive cure rates >90% and low rates of adverse events. Despite these major advancements, treatment of patients with HCV and advanced chronic kidney disease (CKD) is a major challenge due to the lack of efficacy and safety data in this patient population.

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.

Drug Interactions With Direct-Acting Antivirals for Hepatitis C: Implications for HIV and Transplant Patients.

Objective: Review pharmacokinetics of new direct-acting antivirals (DAAs) for hepatitis C (HCV) infection and interactions with concomitant immunosuppressant and antiretroviral therapies (ART).

Data Sources: MEDLINE (1948-January 2015), EMBASE (1964-January 2015), International Pharmaceutical Abstracts (1970-January 2015), Google, and Google Scholar were searched combining the terms simeprevir, sofosbuvir, ledipasvir, daclatasvir, paritaprevir, ABT-450, ombitasvir, dasabuvir, pharmacokinetics, drug interaction, drug metabolism, HIV, antiretroviral, immunosuppressant, transplant. Articles, conference proceedings, abstracts, and product monographs were reviewed.

First confirmed case of native polyomavirus BK nephropathy in a liver transplant recipient seven years post-transplant.

Renal dysfunction frequently occurs in liver transplant recipients and is associated with increased morbidity and mortality. BK virus is a human polyoma virus that reactivates during immunocompromised states and is a known cause of renal allograft dysfunction in renal transplant recipients. However, BK nephropathy of native kidneys is rare in non-renal transplant recipients.

HIV and liver transplantation: The British Columbia experience, 2004 to 2013.

Background: The demand for definitive management of end-stage organ disease in HIV-infected Canadians is growing. Until recently, despite international evidence of good clinical outcomes, HIV-infected Canadians with end-stage liver disease were ineligible for transplantation, except in British Columbia (BC), where the liver transplant program of BC Transplant has accepted these patients for referral, assessment, listing and provision of liver allograft. There is a need to evaluate the experience in BC to determine the issues surrounding liver transplantation in HIV-infected patients.

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.

First successful treatment of post-liver transplant hepatitis C fibrosing cholestatic hepatitis with boceprevir, peginterferon and ribavirin in a pre-transplant null responder.

Fibrosing cholestatic hepatitis (FCH) is a less common but well-recognized severe complication of recurrent hepatitis C virus (HCV) infection post-liver transplant. This condition is fatal without successful treatment and to date; post-transplant antiviral interferon-based antiviral therapy has been associated with guarded success. The new era of protease inhibitors in the treatment of chronic HCV infection may alter the dismal outcome of this condition.

Primary hepatic neuroendocrine tumour requiring live donor liver transplantation: case report and concise review.

Primary hepatic neuroendocrine tumours are rare tumours effecting relatively young patients. As metastatic neuroendocrine tumours to the liver are much more common, extensive investigations are crucial to exclude a primary tumour elsewhere. We report a case of a 27 year old woman who presented with fatigue, increased abdominal girth and feeling of early satiety and bloating.

Spontaneous clearance of hepatitis C infection post-liver transplant: A rare but real phenomenon? A case report and review of the literature.

Recurrent hepatitis C virus (HCV) infection after liver transplantation is a significant cause of morbidity, mortality and graft loss. Spontaneous clearance of recurrent HCV after liver transplant is a rarely reported phenomenon. We report a case of a 66-year-old woman who underwent liver transplantation for HCV cirrhosis (treatment- naive genotype 2) under immunosuppression with tacrolimus, mycophenolate mofetil (MMF), and short-term corticosteroids.

Efficacy of maintenance subcutaneous hepatitis B immune globulin (HBIG) post-transplant for prophylaxis against hepatitis B recurrence.

Background: Patients who receive liver transplantation for chronic hepatitis B infection require long-term combination therapy with hepatitis B immunoglobulin (HBIG) and oral antiviral medication to prophylax against graft re-infection. This study examines the efficacy and patient preference of subcutaneous (SC) administration of HBIG in maintaining anti HBs titres > 100 IU/L.

Materials And Methods: 12 patients who were stable while receiving our standard IM HBIG protocol received an alternate formulation by SC injection, consisting of 10 mL (3120 IU) HBIG as 4 x 2.

Predictors of relapse to significant alcohol drinking after liver transplantation.

Background: End-stage alcoholic liver disease is common, with many of these patients referred for liver transplantation (LT). Alcohol relapse after LT can have detrimental outcomes such as graft loss and can contribute to a negative public perception of LT.

Objective: To identify factors that predict the recurrence of harmful alcohol consumption after LT.

Multimodal therapy for hepatocellular carcinoma: a complementary approach to liver transplantation.

Objective: To evaluate the survival benefit of multimodal therapy for the treatment of HCC.

Background: Orthotopic liver transplantation (OLT) is considered the treatment of choice for selected patients with hepatocellular carcinoma (HCC). However, donor organ shortages and patients whose HCCs exceed OLT criteria require consideration of alternate therapeutic options such as hepatic resection, radiofrequency ablation (RFA), ethanol injection (EI), transarterial chemoembolization (TACE), and chemotherapy (CTX).
