Abstract
BACKGROUND Mammalian target of rapamycin (mTOR) inhibitors following liver transplantation (LT) are used to minimize calcineurin inhibitor (CNI)-related nephrotoxicity. Data about metabolic effects of mTOR inhibitors are still limited. AIM This study aims to determine the renal and metabolic effects of different mTOR inhibitor-based protocols in real-life LT patients. METHODS This is a retrospective cohort study of patients treated with mTOR inhibitors after LT. Demographics, treatment protocols, glomerular filtration rate (GFR), and metabolic parameters were collected over a period of 4 years. Initiation of blood pressure (BP), diabetes mellitus, and lipid medications was also noted. RESULTS Fifty-two LT recipients received mTOR inhibitors. GFR improved significantly (by 1.96 mL/min/year), with greater improvement in patients with baseline renal dysfunction (+13.3 mL/min vs +4.5 mL/min at 3 years). Conversion to an mTOR inhibitor during the first post-transplant year resulted in a more durable improvement in GFR (for 4 years vs only 1 year for later conversion).No significant weight gain or new-onset diabetes mellitus was observed. However, there was some increase in total cholesterol (+7 mg/dL) and blood pressure (+2 mm Hg during the third year and +8 mm Hg in the fourth years), followed by initiation of lipid-lowering and BP medications in 25% and 13% of patients, respectively. CONCLUSIONS Treatment with an mTOR inhibitor following LT resulted in improved kidney functions without significant negative metabolic effects such as weight gain or new-onset diabetes mellitus. This makes mTOR inhibitors a valuable immunosuppressive option in the face of the growing incidence of nonalcoholic steatohepatitis as a leading cause for LT.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 15 countries, and the relative impact of two scenarios was considered: (i) increased treatment efficacy while holding the treated population constant and (ii) increased treatment efficacy and increased annual treated population. Increasing levels of diagnosis and treatment, in combination with improved treatment efficacy, were critical for achieving substantial reductions in disease burden. In most countries, the annual treated population had to increase several fold to achieve the largest reductions in HCV-related morbidity and mortality. This suggests that increased capacity for screening and treatment will be critical in many countries. Birth cohort screening is a helpful tool for maximizing resources. In most of the studied countries, the majority of patients were born between 1945 and 1985.

Abstract
Morbidity and mortality attributable to chronic hepatitis C virus (HCV) infection are increasing in many countries as the infected population ages. Models were developed for 15 countries to quantify and characterize the viremic population, as well as estimate the number of new infections and HCV related deaths from 2013 to 2030. Expert consensus was used to determine current treatment levels and outcomes in each country. In most countries, viremic prevalence has already peaked. In every country studied, prevalence begins to decline before 2030, when current treatment levels were held constant. In contrast, cases of advanced liver disease and liver related deaths will continue to increase through 2030 in most countries. The current treatment paradigm is inadequate if large reductions in HCV related morbidity and mortality are to be achieved.

Abstract
Chronic hepatitis C virus (HCV) infection is a leading cause of liver related morbidity and mortality. In many countries, there is a lack of comprehensive epidemiological data that are crucial in implementing disease control measures as new treatment options become available. Published literature, unpublished data and expert consensus were used to determine key parameters, including prevalence, viremia, genotype and the number of patients diagnosed and treated. In this study of 15 countries, viremic prevalence ranged from 0.13% in the Netherlands to 2.91% in Russia. The largest viremic populations were in India (8 666 000 cases) and Russia (4 162 000 cases). In most countries, males had a higher rate of infections, likely due to higher rates of injection drug use (IDU). Estimates characterizing the infected population are critical to focus screening and treatment efforts as new therapeutic options become available.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is the most common cause of elevated alanine aminotransferase (ALT). NAFLD is associated with insulin resistance and hepatic inflammation. Similarly, patients with depression exhibit insulin resistance and increased inflammatory markers. However, no study has shown a clear association between elevated ALT and the development of depression. The aim of the study was to test whether elevated ALT, a surrogate marker for NAFLD, predicts the development of depression. METHOD The present prospective cohort study investigated 12 180 employed adults referred for health examinations that included fasting blood tests and anthropometric measurements between 2003 and 2010. Exclusion criteria were: baseline minor/major depression, excessive alcohol consumption and other causes for ALT elevation. Depression was evaluated by the eight-item Patient Health Questionnaire (PHQ-8) score. RESULTS The final cohort included 5984 subjects [69.4% men, aged 45.0 (s.d. = 10.24) years]. The incidence rate of minor and major depression was 3.8% and 1.4%, respectively. Elevated ALT was a significant independent predictor for the occurrence of minor [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.40-2.92] and major (OR 3.132, 95% CI 1.81-5.40) depression after adjusting for age, gender, body mass index, education level, serum levels of lipids, glucose, smoking and physical activity. Adding subjective health and affective state parameters (sleep disturbances, self-rated health, anxiety and burnout) as potential mediators only slightly ameliorated the association. Persistently elevated ALT was associated with the greatest risk for minor or major depression as compared with elevation only at baseline or follow-up (p for trend < 0.001). CONCLUSIONS Elevated ALT was associated with developing depressive symptoms, thus suggesting that NAFLD may represent an independent modifiable risk factor for depression.

Abstract
The aim of this study was to determine the effect of adoptive transfer of regulatory natural killer T (NKT) lymphocytes on the metabolic disorder in leptin-deficient ob/ob mice, which feature depletion and defective function of NKT and CD4 lymphocytes. Leptin-deficient ob/ob mice were subjected to transplantation of 1 x 10(6) of either ob/ob or wild-type-derived NKT lymphocytes, or to transplantation of either ob/ob or wild-type-derived splenocytes. The effect on hepatic fat content was measured by magnetic resonance imaging (signal intensity index) and histology, using the steatohepatitis grading scale. The degree of glucose intolerance was measured by an oral glucose tolerance test (GTT). Adoptive transfer of wild-type or ob/ob-derived regulatory NKT cells led to a 12% decrease in hepatic fat content. A significant histological shift from macrosteatosis to microsteatosis was observed. Marked improvement in the GTT was noted in wild-type or ob/ob-derived NKT recipients. Metabolic effects were associated with a significant decrease in peripheral and intrahepatic CD4/CD8 lymphocyte ratios. Intrahepatic CD8 trapping was observed in all responders. Serum interleukin 10 levels decreased significantly. In conclusion, adoptive transfer of a relatively small number of regulatory NKT lymphocytes into ob/ob mice results in a significant reduction in hepatic fat content, a shift from macro to microsteatosis, and significant improvement in glucose intolerance. These effects were associated with decreased peripheral and intrahepatic CD4/CD8 ratios and decreased interleukin 10 levels. The results further support a role for regulatory NKT lymphocytes in the pathogenesis of non-alcoholic steatohepatitis in the leptin-deficient murine model.

Abstract
BACKGROUND Ulcerative colitis (UC) is characterized by a life-long chronic course with remissions and exacerbations. Approximately 15% of patients have a severe attack requiring hospitalization at some time during their illness. These patients are traditionally treated with intravenous corticosteroids, with a response rate of approximately 60%. The patients who do not respond to steroid treatment usually require surgical removal of the large bowel (proctocolectomy or colectomy with an anal pouch). This surgical procedure essentially cures the patient from the disease but is associated with complications such as pouchitis. Few alternative treatments exist for severe ulcerative colitis: immunosuppressive medications (such as azathioprine) have a slow onset of action and are therefore usually ineffective. Antibiotics are not proven to be effective and biological treatments such as infliximab are still under investigation. The introduction of cyclosporine-A (CsA) for use in patients with severe ulcerative colitis (UC) has provided an alternative to patients previously facing only surgical options. Cyclosporine acts mainly by inhibiting T lymphocyte function, which is essential for the propagation of inflammation. Unlike most other immunosuppressive agents, CsA does not suppress the activity of other hematopoietic cells, does not cause bone marrow suppression and has a rapid onset of action. This reviews aims to systematically assess the effectiveness and safety of CsA for severe UC. OBJECTIVES This review aimed to evaluate the effectiveness of cyclosporine A for patients with severe ulcerative colitis. SEARCH STRATEGY Electronic searches of The Cochrane Library (Issue 1, 2004), EMBASE (1980-2004), and MEDLINE (1966-2004); hand searching the references of all identified studies; contacting the first author of each included trial. SELECTION CRITERIA Randomised clinical trials comparing cyclosporine A with placebo or no intervention to obtain and maintain remission of idiopathic ulcerative colitis. DATA COLLECTION AND ANALYSIS Two reviewers independently appraised the quality of each trial and extracted the data from the included trials. Relative risks (RR) with 95% confidence intervals (CI) were estimated. The reviewers assumed an intention to treat analysis for the outcome measures. MAIN RESULTS Only two randomized controlled trials were identified that satisfied the inclusion criteria. These two trials could not be pooled for analysis because of major differences in design and patient populations. In the first trial, 11 patients received intravenous cyclosporine (4 mg/kg) and 9 received placebo. Two of 11 in the treatment group failed to respond to therapy compared with nine of nine in the placebo group (RR 0.18, 95% CI 0.05 - 0.64). However, 3/11 and 4/9 eventually underwent colectomy in the treatment and placebo groups respectively and follow-up was less than a month. In the second trial 15 patients were treated with intravenous cyclosporine and 15 with intravenous methylprednisolone. Five of 15 patients in the cyclosporine group failed to respond to therapy as compared to 7/15 in the methylprednisolone group (RR 0.71, 95% CI 0.29 - 1.75). After 1 year 7/9 responders in the cyclosporine group were still in remission compared with 4/8 in the steroid group (p > 0.05) and the colectomy rate was similar in both groups. The mean time to response in the cyclosporine group in the 2 trials was short (7 days and 5.2 days). These results should be interpreted with caution given the small numbers of trials and patients evaluated for comparison, and limited follow-up (few weeks in one trial to a year in the other). The precise assessment of the occurrence of adverse events was difficult because the trials described different adverse reactions, which reversed after discontinuation of cyclosporine. There was no evidence in the trials reviewed that cyclosporine was more effective than standard treatment for preventing colectomy but this effect cannot be excluded due to the small sample size and rarity of this outcome. Additional limitations of current research include lack of data on quality of life, costs and long-term results of cyclosporine therapy. AUTHORS' CONCLUSIONS There is limited evidence that cyclosporine is more effective than standard treatment alone for severe ulcerative colitis. The relatively quick response makes the short-term use of cyclosporine potentially attractive, but the long-term benefit is unclear, when adverse events such as cyclosporine-induced nephrotoxicity may become more obvious. There is a need for additional research on quality of life, costs and long-term results from cyclosporine therapy in severe ulcerative colitis.

Abstract
Halofuginone, a widely used alkaloid coccidiostat, is a potent inhibitor of collagen alpha 1 (I) and matrix metalloproteinase 2 gene expression. Halofuginone also suppresses extracellular matrix deposition and fibroblast proliferation. It was recently shown to be effective in suppression of bladder carcinoma and glioma. This study sought to evaluate the effect of treatment with halofuginone on growth of hepatocellular carcinoma (HCC) in mice. Athymic Balb/c mice were injected subcutaneously with 10(7) human hepatoma cells (Hep3B), followed by treatment with halofuginone administered in the diet (750 microg/kg) starting on day 3, before tumour innoculation. The control group was received a normal diet. Mice were followed for survival, tumour volume and serum alpha-fetoprotein (alpha FP). The mechanism of the anti-tumour effect of halofuginone was determined in vitro by assessing tumour cell growth, and by measuring the serum concentrations of interferon-gamma (IFN gamma) and interleukin 2 (IL2). Halofuginone treatment induced almost complete tumour suppression in treated mice. Mortality rates were 10% and 50%, in halofuginone-treated and control mice, respectively (P<0.001). No visible tumour was observed in treated mice, as compared with a 364 mm3 tumour in control mice. Serum alpha FP were 0.1 and 212 ng/ml in treated and control mice, respectively (P<0.005). Halofuginone significantly inhibited HCC proliferation in vitro. Maximal inhibition of 64% of tumour cell growth was observed at a concentration of 10(-8) M. The anti-tumour effect was mediated via a significant increase in IFN gamma and IL2 (90 vs. 35, and 210 vs. 34 pg/ml in treated and control groups, respectively, P<0.005). Treatment with halofuginone effectively suppressed the progression of HCC in mice. This effect may be associated with a direct anti-tumour effect, and/or enhancement of a systemic immune response.

Abstract
"Ecstasy" (3,4-Methylenedioxymethamphetamine), is used as a mood enhancer. We describe a case of a 23 year-old male suffering from thrombotic thrombocytopenic purpura (TTP), and severe hepatitis following ingestion of ecstasy. We describe the various hepatic complications, including hepatitis, cirrhosis, and hepatic failure, in addition to the hematological complications including DIC and TTP secondary to ecstasy abuse. Ecstasy abuse should be considered in every patient with unexplained hepatic or hematologic complications.

Abstract
To investigate the potential direct nephrotoxicity of Shiga toxin, a putative mediator for hemolytic uremic syndrome, purified toxin (10(-11) M) was added to isolated rat kidneys perfused for 160 min with a Krebs-Henseleit acellular medium enriched with albumin and amino acids. Kidney function and morphology were examined after perfusion with the Shiga toxin vs controls. Shiga toxin did not significantly alter renal perfusion flow, glomerular filtration rate, or tubular sodium reabsorption, but it significantly increased urinary protein excretion (from 61 +/- 23 to 169 +/- 28 microg/min, P < 0.01). On renal morphologic study, Shiga toxin did not induce gross glomerular damage but increased markedly the injury to the medullary thick ascending limbs. In conclusion, Shiga toxin is toxic to rat kidneys ex vivo and in the absence of platelets. Renal damage is manifested by proteinuria and medullary tubular injury. The distribution of this injury suggests a possible synergism between local medullary hypoxia and the toxic tubular or endothelial effects of the toxin. These effects may play a pathogenic role in the tubulo-interstitial injury observed in hemolytic uremic syndrome associated with severe renal failure.
