Social Impact of Hepatic Encephalopathy.

Hepatic encephalopathy is a medical condition that stems from liver dysfunction, leading to the accumulation of toxins in the bloodstream. This can result in cognitive impairments, mood changes, and motor dysfunction. Its social impact includes challenges in employment, relationships, and daily functioning for affected individuals. Stigma and misunderstanding around the condition can further exacerbate the difficulties faced by both patients and their caregivers. Efforts to raise awareness, improve medical management, and provide support systems can help mitigate the social impact of hepatic encephalopathy.

Barriers for Liver Transplant in Patients with Alcohol-Related Hepatitis.

BACKGROUND: Liver transplantation (LT) for alcohol-related liver disease has historically been reserved for patients who have been six months abstinent. Given the increasing incidence of alcohol-related hepatitis (AH) and dismal survival in patients who fail medical therapy, transplant centers are extending their acceptance criteria for patients with less than 6 months of sobriety. We sought to determine the barriers for listing. METHODS: We conducted a retrospective chart review of all inpatient LT referrals for a diagnosis of AH between September 2019 and December 2020. LT evaluations were performed by a multidisciplinary team. Descriptive statistics were reported using mean and standard deviation (SD) or percentage where appropriate. RESULTS: During our study period, 82 patients were evaluated for LT. Of these 82 patients, 62 were declined for liver transplantation. The mean (SD) age of the 62-patient cohort was 44 years (10.7), and most patients were men. The mean (SD) number of reasons for denial was 2 (0.97). Four patients had medical contraindications for transplant. Twenty-seven (44%) and 35 (56%) patients lacked insight and were at risk of alcohol relapse, respectively. Forty-three (69%) and fourteen (22.5%) patients had insufficient social support and an inability to maintain a therapeutic relationship with the transplant team, respectively. CONCLUSION: Patients are more likely denied for psychosocial factors than medical comorbidities. The majority were due to lack of insight, insufficient social support, and inability to maintain a therapeutic relationship with the transplant team. Resources should be allocated to address these issues.

Long-term outcomes with oral therapy in liver transplant recipients with hepatitis B.

BACKGROUND: The long-term impact of oral hepatitis B antiviral therapy in liver transplant (LT) recipients is currently underexplored. The objective of this study was to evaluate how oral antiviral agents impact long-term renal function in this population. METHODS: We studied 79 patients who received a LT for hepatitis B and were placed on all-oral antiviral therapy after withdrawing from hepatitis B immune globulin therapy at the University of California, Los Angeles. Laboratory data were obtained through a retrospective chart review. Univariate analysis and two-sided t tests were performed. RESULTS: The mean (±SD [standard deviation]) age at the time of LT was 65.4 (± 8.2) years. The overall mean (±SD) follow-up from LT was 6.5 (±3.3) years. 22.8% (18/79) of recipients on all-oral therapy had worsening of their chronic kidney disease stage, and 17.7% (14/79) had an increase in creatinine of at least 0.3 mg/dL. There were no significant changes in creatinine and GFR in patients while on tenofovir alafenamide. Patient survival was decreased for recipients who developed detectable HBsAg. CONCLUSION: Tenofovir alafenamide appears to have less of an impact on renal function in LT recipients than other antiviral agents. HBV recurrence after transplant is associated with decreased patient survival and remains an important issue to address for LT recipients on oral antiviral therapy.

Elimination of Hepatitis C in Liver Transplant Recipients.

Background and Aims: Recurrent hepatitis C (HCV) disease in liver transplant (LT) recipients is associated with significant morbidity and mortality. With the availability of noninterferon-based therapy, eliminating HCV may be achievable in LT recipients. Methods: We studied all consecutive recipients who underwent LT at the University of California Los Angeles between January 2005 and June 2017. We collected data on date of transplant and last follow-up, as well as laboratory values. We also recorded type and timing of antiviral therapy relative to LT. Analyses were performed to assess the proportion of LT recipients who are viremic after transplant. Results: Six hundred thirty-four patients underwent LT with a diagnosis of HCV. There was a statistically significant trend for patients to be cured before (p < 0.001) and after liver transplantation (p < 0.001) for the study period of 2014 to 2016 relative to 2005 and 2013, respectively. Of the 634 recipients eligible for therapy, 8% and 74% were treated within 12 months of transplant for the study periods 2005 to 2013 and 2014 to 2016, respectively. There was a significant decrease between the two study periods in the proportion of patients undergoing re-LT 1 year after the original LT: 5.5% (n = 28/510) and 1.5% (n = 2/124) respectively for study periods 2005 to 2013 and 2014 to 2016 respectively (p = 0.011). Conclusions: The proportion of LT recipients who are viremic has decreased over time. Eliminating HCV in LT recipients is feasible after the introduction of direct-acting agents. Curing HCV should translate to improved clinical outcomes in LT recipients who were transplanted for HCV infection with longer follow-up. Preliminary results suggest the decreased need for transplant in the direct-acting agents era.

Hepatitis C and human immunodeficiency virus coinfection in the era of direct-acting antiviral agents: No longer a difficult-to-treat population.

The treatment of chronic hepatitis C (HCV) in human immunodeficiency virus 1 (HIV)-infected individuals has been historically marked by low sustained virologic response (SVR) rates in comparison to those without HIV infection, resulting in the Food and Drug Administration labeling those coinfected as a "special population with an unmet medical need." We systematically reviewed the treatment of chronic HCV infection in those infected with HIV. We propose that with the advent of direct-acting antiviral (DAA) agents, patients coinfected with HCV and HIV have similar SVR rates as HCV-monoinfected persons and that DAAs address an unmet medical need in this population. A review was performed using Medical Subject Heading terms within the PubMed, EMBASE, and Cochrane Library databases to search for studies dated between January 2004 and July 2017. Keywords used in the study included "hepatitis C," "HIV," "coinfection," and "direct-acting antiviral." SVR rates for those with HCV and HIV coinfection treated with interferon-based therapies were substantially lower that SVR rates of HCV-monoinfected individuals. The advent of DAA agents has resulted in similar SVR rates between monoinfected and coinfected individuals, with SVR >93%. These medications have been demonstrated to have improved safety, efficacy, and tolerability in comparison to interferon-based regimens. CONCLUSION: The designation of a "special population" for those with coinfection requires reconsideration; DAA therapies have resulted in similarly high rates of SVR for HCV infection in those with and without HIV infection; despite these improvements, however, clinicians must be cognizant of negative predictors of SVR and barriers to treatment that may be more common in the coinfected population.

Hepatitis C Virus Prevalence in Egyptian Americans in Southern California.

BACKGROUND: Hepatitis C virus (HCV) is a global medical health concern. Egypt has the highest HCV prevalence. Few studies have assessed the HCV prevalence rates among Egyptian-born expatriates. We sought to define the HCV prevalence Egyptian-born individuals residing in the Southern California area. PATIENTS AND METHODS: We screened Egyptian-born individuals in houses of worship in the Southern California area using a point of care test HCV antibody test. Results were confirmed by testing the blood for viral load. Demographic information including risk factors were also collected. Individuals were contacted with their results, and those found to be detectable HCV antibodies were referred for further testing and additional care. RESULTS: Three hundred twenty-six Egyptian expatriates from 7 houses of worship in Southern California were screened for the HCV infection. Most of the participants were screened at Coptic Churches. Nine of these individuals were found to be HCV infected (2.8%). We found an increased HCV seroprevalence in subjects were male and born in Egyptian urban areas. Five of the 9 subjects (56%) who tested positive were not baby boomers and only 2 of these 9 subjects (22%) had recognized Center for Disease Control risk factors. CONCLUSIONS: The HCV prevalence rate of Egyptian-born individuals living in the Southern California area was lower compared with the prevalence rate in the general Egyptian population, but higher than that seen in the general US population. The utility of using Center for Disease Control risk factors to define individuals at risk of HCV among Egyptian expatriates is not applicable.

Bariatric Surgery and Liver Transplantation.

Obesity is an important public health and medical concern in the United States. The rate of obesity has steadily risen for the past several decades. Obesity is associated with the development of nonalcoholic steatohepatitis, which is one of the leading indications for liver transplantation. After liver transplantation, recipients tend to gain weight and develop recurrent fatty liver. Over time, recurrent fatty liver may impact patient and graft survival. A bariatric surgical approach may be beneficial in select patients.

Timing of Hepatitis C Antiviral Therapy in Liver Transplant Recipients With Direct-acting Agents.

Chronic hepatitis C virus infection is a substantial health care burden worldwide and is the leading cause of liver transplant in adults. In patients with detectable hepatitis C virus RNA at the time of transplant, interferon-based therapies for hepatitis C virus were poorly tolerated with low virologic response rates. Although reinfection after transplant is inevitable, the recent advent of direct-acting antiviral agents has revolutionized treatment of hepatitis C virus in the pre- and posttransplant settings. These antiviral agents have been shown to have high-sustained virologic response rates, shorter courses of treatment, and decreased frequencies of adverse effects. Here, we review the current literature on the use of direct-acting agents for treatment of patients with hepatitis C virus before and after liver transplant.

Probiotics are helpful in hepatic encephalopathy: a meta-analysis of randomized trials.

BACKGROUND: Hepatic encephalopathy (HE) is a major complication of cirrhosis and is associated with decreased survival and increased health care utilization. AIM: The aim of this study was to evaluate the efficacy of probiotics in the management minimal hepatic encephalopathy HE (MHE) and overt HE (OHE) in comparison to no treatment/placebo and lactulose. METHODS: The main outcomes measured were mortality, improvement in MHE, progression to OHE in patients with MHE and hospitalization. We calculated odds ratios (OR) with 95% confidence intervals (CI). Study heterogeneity was assessed using the I(2) statistic. RESULTS: Fourteen studies totalling 1152 patients were included in the analysis. The use of probiotics had no impact on the overall mortality when compared to either lactulose (OR: 1.07, 95% CI: 0.47-2.44, P = 0.88) or no treatment/placebo (OR: 0.69, 95% CI: 0.42-1.14, P = 0.15). When probiotics was compared to no treatment/placebo, it was associated with a significant improvement in MHE (OR: 3.91, 95% CI: 2.25-6.80, P < 0.00001), decreased hospitalization rates (OR: 0.53, 95% CI: 0.33-0.86, P = 0.01) and decreased progression to overt hepatic encephalopathy (OR: 0.40, 95% CI: 0.26-0.60, P < 0.0001). However when compared to lactulose, probiotics did not show a significant difference in improvement of MHE (OR: 0.81, 95% CI: 0.52-1.27, P = 0.35), hospitalization rates (OR: 1.02, 95% CI: 0.52-1.99, P = 0.96) or progression to overt hepatic encephalopathy (OR: 1.24, 95% CI 0.73-2.10, P = 0.42). CONCLUSIONS: Overall the use of probiotics was more effective in decreasing hospitalization rates, improving MHE and preventing progression to OHE in patients with underlying MHE than placebo, but similar to that seen with lactulose. The use of probiotics did not affect mortality rates.
