Monocyte up-regulation of CTRs in response to LPS caused hypersensitivity to diverse microbial and host-derived byproducts, indicating a secondary immune surveillance pathway up-regulated in a subset of cells by a closely associated genomic cassette. Finally, expression of CTR genes was higher in livers of patients with severe AH, but not other chronic liver diseases, implicating secondary immune surveillance in nonresolving inflammation in severe AH.Myeloperoxidase (MPO) activity has been associated with the metabolic syndrome, cardiovascular and liver disease. Here, we evaluate the therapeutic potential of MPO inhibition on nonalcoholic steatohepatitis (NASH) and NASH-induced fibrosis, the main determinant of outcomes. MPO plasma levels were elevated in patients with nonalcoholic fatty liver disease (NAFLD) compared with healthy controls. In a second cohort, hepatic MPO messenger RNA expression correlated with higher body mass index and hemoglobin A1c, both being risk factors for NAFLD. We could establish by immunohistochemistry that MPO-positive cells were recruited to the liver in various mouse models of fibrogenic liver injury, including bile duct ligation, carbon tetrachloride (CCl4) treatment, spontaneous liver fibrogenesis in multidrug resistance 2 knockout (MDR2 KO) mice, and NASH-inducing diet. Comparison of MPO-deficient mice and their wild-type littermates exposed to a high-caloric diet revealed that MPO deficiency protects against NASH-related liver injury and fibrosis. In line with this, hepatic gene expression analysis demonstrated a MPO-dependent activation of pathways relevant for wound healing, inflammation, and cell death in NASH. MPO deficiency did not affect NAFLD-independent liver injury and fibrosis in MDR2 KO or CCl4-treated mice. Finally, we treated wild-type mice exposed to NASH-inducing diet with an oral MPO inhibitor. Pharmacological MPO inhibition not only reduced markers of MPO-mediated liver damage, serum alanine aminotransferase levels, and hepatic steatosis, but also significantly decreased NASH-induced liver fibrosis. MPO inhibitor treatment, but not MPO deficiency, significantly altered gut microbiota including a significant expansion of Akkermansia muciniphila. Conclusions MPO specifically promotes NASH-induced liver fibrosis. Pharmacological MPO inhibition attenuates NASH progression and NASH-induced liver fibrosis in mice and is associated with beneficial changes of intestinal microbiota.Hypogonadism affects hepatic lipid metabolism and is expected to promote nonalcoholic fatty liver disease (NAFLD). The aims of this study were to determine (1) the prevalence of NAFLD in hypogonadal males and (2) the impact of correction of hypogonadism by LPCN 1144 (Lipocine, Inc., Salt Lake City, UT), an oral testosterone prodrug, on NAFLD in this population. Data were derived from a multicenter open-label single-arm trial of LPCN 1144 for hypogonadal males, in which a subset (n = 36) had serial magnetic resonance imaging-proton density fat fraction measurements (National Clinical Trial 03868059). NAFLD prevalence, defined by magnetic resonance imaging-proton density fat fraction ≥5%, was 66%. Eighty-one percent of those with baseline liver fat (BL) ≥5% had improvement in liver fat content, and NAFLD resolved in 33% of subjects at 8 weeks (mean relative reduction 45%) and 48% (mean relative reduction 55%) after 16 weeks of LPCN 1144 therapy. The reduction in liver fat was greater in those with higher BL (BL ≥5% 71%; BL ≥8% 80%; and BL ≥10% 75%). Normalization rate of alanine aminotransferase and gamma-glutamyltransferase greater than the upper limit of normal range were 100% and 50% of treated patients, respectively. LPCN 1144 was not associated with major adverse events. Conclusion Treatment with LPCN 1144 (oral T prodrug) in hypogonadal males with NAFLD resolved NAFLD in approximately half of the affected patients without any safety signals. Further studies are needed to validate its use in hypogonadal males with nonalcoholic steatohepatitis.Nonalcoholic fatty liver disease (NAFLD) is closely associated with obesity. The prevalence of extreme obesity, defined as body mass index (BMI) of 50 kg/m2 or higher, is rising more rapidly than overall obesity. We aimed to compare the clinical outcomes and performance of noninvasive fibrosis assessment tools in NAFLD with or without extreme obesity. A retrospective analysis was performed in 304 patients with NAFLD with extreme obesity and compared them to patients with NAFLD with BMI of 40 kg/m2 or less, matched for age, gender, race, and liver fibrosis stage. The mean age of the NAFLD with extreme obesity cohort was 55.9 years, BMI 55 kg/m2, and 49.7% had cirrhosis at initial evaluation. Baseline cirrhosis and coronary artery disease were associated with increased risk of death, and dyslipidemia with decreased risk of mortality. Age, insulin use, hypertension, albumin and platelet count were associated with cirrhosis. Fifteen percent of patients had weight-loss surgery, but this was not associated with survival or risk of cirrhosis. Of the 850 abdominal ultrasound scans performed in 255 patients, 24.1% were deemed suboptimal for hepatocellular carcinoma screening. The mean NAFLD fibrosis score (NFS) in the extreme obesity cohort, versus a propensity-matched cohort with BMI of 40 kg/m2 or less, was significantly different for both low fibrosis (F0-F2) (0.222 vs. -1.682, P less then 0.0001) and high fibrosis (F3-F4) (2.216 vs. 0.557, P less then 0.001). Conclusion NAFLD with extreme obesity is associated with increased risk of liver-related and overall mortality. Accurate noninvasive assessment of liver fibrosis, low rates of weight loss surgery, and high failure rate of ultrasound were identified as clinical challenges in this population.Chronic Liver Disease (CLD) is associated with an increased risk of chronic kidney disease (CKD). However, the health care burden of CKD in the CLD spectrum is unknown. We aimed to evaluate the health care use and cost burdens associated with CKD in patients with CLD in the United States by using real-world claims data. We analyzed data from the Truven Health MarketScan Commercial Claims database from 2010 to 2015. A total of 19,664 patients with CLD with or without comorbid CKD were identified using International Classification of Diseases, Ninth Revision, codes and matched 11 by sociodemographic characteristics and comorbidities using propensity scores. read more Total and service-specific unadjusted and adjusted health care parameters were analyzed for the 12 months following an index date selected at random to capture whole disease burdens. In CLD, comorbid CKD was associated with a higher annual number of claims per person (CKD vs. no CKD, 69 vs. 55) and higher total annual median health care costs (CKD vs. no CKD, $21,397 vs.
