Clinical Food Addiction Is Not Associated with Development of Metabolic Complications in Liver Transplant Recipients.

Background and Aims: Given the increased risk of post-transplant metabolic syndrome (PTMS; defined by hypertension, diabetes mellitus and hyperlipidemia), we aimed to identify the potential role of food addiction in the development of metabolic complications in the post-liver transplant population. Methods: Inclusion criteria included adult liver transplant recipients followed at our institution between June 2016 and November 2016. Participants were administered a demographic survey as well as the Yale Food Assessment Scale 2.0, a 35-item questionnaire used to assess frequency of food addiction in accordance with the DSM-V guidelines of substance use disorders. Demographic and clinical data were collected. Results: Our study included 236 liver transplant recipients (139 males, 97 females). The median (interquartile range [IQR]) BMI of participants was 26.8 kg/m2 (24.2, 30.4), and median (IQR) time since transplantation was 50.9 months (19.6, 119.8). The prevalence rates of hypertension, hypercholesterolemia and diabetes mellitus were 54.7%, 25.0% and 27.1%, respectively. Twelve participants (5.1%) were found to have a diagnosis of food addiction. A diagnosis of food misuse was made in 94 (39.8%) of the transplant recipients. Conclusions: Our findings are consistent with prior data that indicate high prevalence of metabolic complications among liver transplant recipients. Food addiction was not predictive of metabolic complications within this population. Nevertheless, we found that this population was at high risk of demonstrating symptoms of food misuse, and they were not likely to appreciate the risks of pathologic patterns of eating. Given the increasing risk of cardiovascular morbidity and mortality in this population, efforts should be made to identify risk factors for the development of PTMS.

Boceprevir in liver transplant recipients.

BACKGROUND: There has been increasing interest in using protease inhibitors with pegylated interferon and ribavirin to treat recurrent hepatitis C (HCV) disease in liver transplant recipients. METHODS: We retrospectively evaluated the safety and efficacy in liver transplant recipients treated for recurrent hepatitis C genotype 1 with the combination of peginterferon, ribavirin and boceprevir. RESULTS: Twenty liver transplant recipients were treated for recurrent hepatitis C. Baseline alanine aminotransferase, total bilirubin and HCV RNA values (± SD) were 67.5 (±50.9) mg/dl, 1.78 (±1.99) U/L, and 16 955 510 (±21 620 675) IU/ml. Anaemia was a common adverse event requiring epoetin in 16 of 20 recipients and ribavirin dose reductions in 17 of 20 recipients. One-third of recipients required a blood transfusion. Filgrastim was used in 11 of 20 patients (55%) and eltrombopag in two of 20 recipients (10%) over the course of treatment. Serum creatinine level increased significantly from a baseline value of 1.33 mg/dl to 1.59 mg/dl at week 20 of boceprevir (P < 0.005). The overall sustained viral response (SVR) was 50%. Of the 14 patients who had a viral load less than 1000 IU/ml at week 4 of boceprevir, the SVR was 71%. The SVR was 83% of the 11 patients who had undetectable viral levels at week 4 of boceprevir. CONCLUSIONS: Antiviral therapy utilizing boceprevir in liver transplant recipients requires close monitoring. Anaemia and neutropenia were common requiring growth factors in most recipients. On-treatment viral responses appear promising but long-term data are needed.

Strategies for the prevention of recurrent hepatitis B virus infection after liver transplantation.

Hepatitis B virus (HBV) infection is an international public health concern, and chronic infection can lead to the development of cirrhosis, liver failure, or hepatocellular carcinoma as well as the need for liver transplantation. The recurrence of HBV infection following liver transplantation was disproportionately high prior to the introduction of proper prophylactic treatment. Risk factors associated with the recurrence of HBV infection post-transplant include hepatitis B e antigen positivity, high levels of serum HBV DNA, and the presence of an antiviral drug-resistant strain prior to transplantation. The prevention of HBV recurrence began with the introduction of hepatitis B immunoglobulin (HBIG) in the early 1 990s. Nucleos(t)ide analog (NA) antiviral drugs were next to be introduced and, in combination with HBIG, are considered to be extremely effective for the prevention of recurrence. Because of concerns with HBIG, whether HBIG can be used for a short time or discontinued altogether is under debate. All of the NA antiviral drugs have been proven to be effective against HBV, at least in the pretransplant setting, and can be used safely posttransplant. Further investigation is still needed to standardize treatment in the posttransplant setting.

Hepatitis C and work impairment: a review of current literature.

Approximately 2.7 to 4.1 million people have chronic hepatitis C (HCV) in the United States. Although often thought of as an asymptomatic disease, several studies have revealed that those with chronic HCV experience increased work impairment manifested as decreased work productivity and increased absenteeism and presenteeism (attending work while being impaired). This review article summarizes the current literature examining the link between chronic HCV and work impairment for those with and without treatment and liver transplant recipients. We searched PubMed for epidemiological studies of HCV and its effect on worker productivity. We used a combination of the keywords "Hepatitis C," "disability," "work," "occupation," "labor," "productivity," and "absenteeism." Multiple studies were identified in our search and all confirmed the hypothesis that chronic HCV infection, with and without active treatment, lead to decreased work productivity and increased absenteeism. This was also found to be true for those who had undergone liver transplantation. Those living with chronic HCV infection experience increased work impairment manifested as decreased work productivity and increased absenteeism. This was found to be true whether or not patients were undergoing active treatment and for liver transplant recipients. Identifying a trend toward increased disability in patients with chronic HCV can help promote appropriate health care, government, and work allocation of resources to help minimize economic, social, and health burdens.
