Project description:BackgroundAcute-on-chronic liver failure (ACLF) is characterized by a systemic inflammatory response, predominantly associated with hepatitis B virus in the Asia-Pacific region, with a high short-term mortality rate. The platelet to high-density lipoprotein ratio (PHR) has been used to predict the prognosis of patients with various inflammatory diseases. We aim to is to use the PHR to predict the short-term prognosis of patients with HBV-ACLF.MethodIn this study, we retrospectively analyzed clinical data from 270 HBV-ACLF patients. Using logistic regression, we identified independent risk factors for short-term mortality and developed a prognostic model. This model was then validated, compared, and its clinical utility assessed via decision curve analysis (DCA).ResultsAmong the 270 HBV-ACLF patients, 98 patients died within 28 days. The deceased group exhibited a higher proportion of severe hepatic encephalopathy and ascites. Additionally, there was a statistically significant difference (P = 0.046) in the novel inflammation scoring system, PHR, between the two groups. Following stringent variable selection, PHR was identified as a predictive factor for short-term mortality in HBV-ACLF patients using logistic regression analysis (OR: 0.835 (0.756-0.999), P = 0.009), and it exhibited a synergistic effect with certain traditional scores. The prognostic model constructed based on PHR demonstrated a superior ability to predict short-term mortality compared to traditional scores such as Child-Turcotte-Pugh (AUC: 0.889). Evaluation using calibration curves and decision curve analysis (DCA) suggested its practical utility.ConclusionPHR can predict short-term mortality in patients, with a low PHR upon admission being associated with an increased risk of death.

Project description:BackgroundHepatic encephalopathy (HE) is a common feature of acute liver failure and has been reported to be associated with poor outcomes. Ammonia is thought to be central to the pathogenesis of HE, but its role in hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is unclear. The present study aimed to assess the prognostic role of ammonia level for patients with HBV-ACLF.MethodsWe retrospectively recruited 127 patients diagnosed with HBV-ACLF for the present study.ResultsAmmonia levels at the time of admission were higher among non-surviving participants than in survivors. Increased ammonia level was found to be associated with severe liver disease and was identified as an independent predictor for mortality in patients with HBV-ACLF.ConclusionsOur results suggest that high ammonia level at admission is an independent factor for predicting short-term mortality in patients with HBV-ACLF. Therefore, ammonia levels may represent a therapeutic target for this condition.

Project description:Background and Aims: Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) remains a serious entity with high mortality. Growth hormone (GH) is related to the liver metabolism and regeneration. The present study aimed to explore the changes and prognostic efficacy of GH on the outcome of HBV-ACLF. Methods: A prospective cohort of 124 patients and a cross-sectional cohort of 142 subjects were enrolled. GH and insulin-like growth factor-1(IGF-1) were detected by ELISA. Thirty-day survival was collected and the association between GH and the 30-day mortality of HBV-ACLF was analyzed. Results: The mean age of the whole prospective cohort was 46.61 ± 12.71 years, and 19 (15.3%) patients were female. The median (IQR) of GH levels in non-survivors were 1106.55 (674.25, 1922.4) pg/ml, which were significantly lower than in survivors (p < 0.001). In the cross-sectional cohort, GH level was significantly higher in liver cirrhosis - acute decompensation (LC-AD) group than liver cirrhosis (LC) group (p < 0.001) while IGF-1 decreased significantly in LC, LC-AD, ACLF groups than health control (HC) and chronic Hepatitis B (CHB) groups (p < 0.001). The area under the receiver operating characteristic curve (AUROC) of GH for predicting 30-day mortality was 0.793. We built a new prognostic model, namely MELD-GH, which showed better predictive efficacy than Child-Pugh, MELD, CLIF-SOFA, and CLIF-C ACLF scores. Conclusions: Low GH predicted the poor outcome of HBV-ACLF patients. GH and IGF-1 levels were differently distributed among HC, CHB, LC, LC-AD, and ACLF patients. MELD-GH had better predictive accuracy when compared to Child-Pugh, MELD, CLIF-SOFA, and CLIF-C ACLF scores.

Project description:BackgroundNeutrophils serve as critical players in the pathogenesis of liver diseases. Chemokine receptors CXCR1 and CXCR2 are required for neutrophil chemotaxis to the site of inflammation/injury and are crucial in hepatic inflammatory response. However, key mechanism of neutrophil-mediated liver injury in acute-on-chronic liver failure (ACLF) remains highly elusive; which could be targeted for the development of new therapeutic interventions.MethodsTo demonstrate the role of CXCR1/CXCR2-expressing neutrophils in hepatic injury, we investigated CXCR1/CXCR2 receptor expression in 17 hepatitis B virus-related ACLF patients in comparison to 42 chronic hepatitis B and 18 healthy controls. Mechanism of neutrophil-mediated cell death was analyzed by in vitro coculture assays and correlated with the patient data. In addition, to find out any etiological-based variations in ACLF, 19 alcohol-related ACLF patients were also included.ResultsIn ACLF, neutrophils have high expression of CXCR1/CXCR2 receptors, which potentially participate in hepatocyte death through early apoptosis and necrosis in contact-dependent and -independent mechanisms. Importantly, blockade of CXCR1/CXCR2 with SCH 527123 antagonist significantly reduced cell death by targeting both the mechanisms. No etiology-based differences were seen between ACLF groups. Importantly, absolute neutrophil count was particularly higher in clinically severe ACLF patients and non-survivors (p < 0.0001). Multivariate analysis demonstrated ANC and CXCL8/IL-8 as a predictor of mortality. Further, receiver operating characteristics curve confirmed the cutoff of ANC >73.5% (sensitivity: 76.5% and specificity: 76.5%) and CXCL8/IL-8 >27% (sensitivity: 70% and specificity: 73%) in prediction of mortality.ConclusionBlockade of CXCR1/CXCR2 diminished the production of inflammatory mediators and reduced cell death; therefore, pharmacological neutralization of CXCR1/CXCR2 could provide novel therapeutic target in the management of ACLF.

Project description:BackgroundAcute-on-chronic liver failure (ACLF) is divided into three types according to the underlying liver disease: non-cirrhosis (type A), compensated cirrhosis (type B) and decompensated cirrhosis (type C). However, whether the underlying chronic liver diseases impact the ACLF prognosis is not clear. The present study aimed to compare the characteristics and outcomes of type A and type B hepatitis B virus (HBV)-ACLF patients.MethodsAccording to the European Association for the Study of Liver-Chronic Liver Failure (EASL-CLIF) diagnostic criteria, 86 type A HBV-ACLF and 71 type B HBV-ACLF were prospectively enrolled. The demography and laboratory data, organ failures, ACLF grades and prognosis were evaluated. Univariate and multivariate Cox regression analyses were performed to analyze the prognostic factors.ResultsThe 28-day and 90-day mortality rates of type A and type B ACLF were 20.9 vs. 60.6% and 34.9 vs. 73.2%, respectively (both P < 0.001). Patients with type A ACLF were younger, had higher viral load and higher levels of alanine aminotransferase and aspartate aminotransferase, platelet count, serum albumin and sodium, international normalized ratio and alpha-fetoprotein, lower rate of ascites, lower Child-Pugh scores and CLIF sequential organ failure assessment scores, higher rate of coagulation failure. Type B ACLF had more renal and cerebral failure. Cirrhosis was one of the independent prognostic factors [hazard ratio, 2.4 (95% CI, 1.451-3.818) P < 0.001].ConclusionACLF developing on noncirrhotic chronic hepatitis B had more serious liver inflammation but fewer extrahepatic organ failures and better outcome than ACLF developing from compensated HBV cirrhosis.

Project description:Background. Platelet to white blood cell ratio (PWR) was an independent prognostic predictor for outcomes in some diseases. However, the prognostic role of PWR is still unclear in patients with hepatitis B related acute-on-chronic liver failure (ACLF). In this study, we evaluated the clinical performances of PWR in predicting prognosis in HBV-related ACLF. Methods. A total of 530 subjects were recruited, including 97 healthy controls and 433 with HBV-related ACLF. Liver function, prothrombin time activity (PTA), international normalized ratio (INR), HBV DNA measurement, and routine hematological testing were performed at admission. Results. At baseline, PWR in patients with HBV-related ACLF (14.03 ± 7.17) was significantly decreased compared to those in healthy controls (39.16 ± 9.80). Reduced PWR values were clinically associated with the severity of liver disease and the increased mortality rate. Furthermore, PWR may be an inexpensive, easily accessible, and significant independent prognostic index for mortality on multivariate analysis (HR = 0.660, 95% CI: 0.438-0.996, p = 0.048) as well as model for end-stage liver disease (MELD) score. Conclusions. The PWR values were markedly decreased in ACLF patients compared with healthy controls and associated with severe liver disease. Moreover, PWR was an independent prognostic indicator for the mortality rate in patients with ACLF. This investigation highlights that PWR comprised a useful biomarker for prediction of liver severity.

Project description:Background and aimsDynamic evaluation of critically ill patients is the key to predicting their outcomes. Most scores based on the Model for End-stage Liver Disease (MELD) and acute-on-chronic liver failure (ACLF) utilize point-in-time assessment. This study mainly aimed to investigate the impact of dynamic clinical course change on post-liver transplantation (LT) survival.MethodsThis study included 637 adults (overall cohort) with benign end-stage liver diseases. The authors compared the MELD scores and our ACLF-based dynamic evaluation scores. Patients enrolled or transplanted with ACLF-3 were defined as the ACLF-3 cohort ( n =158). The primary outcome was 1-year mortality. ΔMELD and ΔCLIF-OF (Chronic Liver Failure-Organ Failure) represented the respective dynamic changes in liver transplant function. Discrimination was assessed using the area under the curve. A Cox regression analysis identified independent risk factors for specific organ failure and 1-year mortality.ResultsPatients were grouped into three groups: the deterioration group (D), the stable group (S), and the improvement group (I). The deterioration group (ΔCLIF-OF ≥2) was more likely to receive national liver allocation ( P =0.012) but experienced longer cold ischemia time ( P =0.006) than other groups. The area under the curves for ΔCLIF-OF were 0.752 for the entire cohort and 0.767 for ACLF-3 cohorts, both superior to ΔMELD ( P <0.001 for both). Compared to the improvement group, the 1-year mortality hazard ratios (HR) of the deterioration group were 12.57 (6.72-23.48) for the overall cohort and 7.00 (3.73-13.09) for the ACLF-3 cohort. Extrahepatic organs subscore change (HR=1.783 (1.266-2.512) for neurologic; 1.653 (1.205-2.269) for circulation; 1.906 (1.324-2.743) for respiration; 1.473 (1.097-1.976) for renal) were key to transplantation outcomes in the ACLF-3 cohort. CLIF-OF at LT (HR=1.193), ΔCLIF-OF (HR=1.354), and cold ischemia time (HR=1.077) were independent risk factors of mortality for the overall cohort, while ΔCLIF-OF (HR=1.384) was the only independent risk factor for the ACLF-3 cohort. Non-ACLF-3 patients showed a higher survival rate than patients with ACLF-3 in all groups ( P =0.002 for I, P =0.005 for S, and P =0.001 for D).ConclusionThis was the first ACLF-based dynamic evaluation study. ΔCLIF-OF was a more powerful predictor of post-LT mortality than ΔMELD. Extrahepatic organ failures were core risk factors for ACLF-3 patients. CLIF-OF at LT, ΔCLIF-OF, and cold ischemia time were independent risk factors for post-LT mortality. Patients with a worse baseline condition and a deteriorating clinical course had the worst prognosis. Dynamic evaluation was important in risk stratification and recipient selection.

Project description:RationaleHyponatremia is associated with decompensated heart failure and poor prognosis in patients with left ventricular systolic dysfunction.ObjectivesWe sought to determine if hyponatremia is associated with right heart failure and worse prognosis in patients with pulmonary arterial hypertension (PAH).MethodsWe prospectively followed 40 patients with PAH and examined the relationship between serum sodium and right heart function as well as survival.Measurements and main resultsSubjects with hyponatremia (Na < or = 136 mEq/L) were more symptomatic (11/13 World Health Organization [WHO] class III/IV vs. 12/27 WHO class III/IV; P = 0.02), had more peripheral edema (69 vs. 26%; P = 0.009), and had higher hospitalization rates (85 vs. 41%; P = 0.009) than normonatremic subjects. Hyponatremic subjects had higher right atrial pressure (14 +/- 6 vs. 9 +/- 3 mm Hg; P < 0.001), lower stroke volume index (21 +/- 7 vs. 32 +/- 10 ml/m(2); P < 0.01), larger right ventricular:left ventricular area ratio (1.8 +/- 0.4 vs. 1.3 +/- 0.4; P < 0.001), and lower tricuspid annular plane systolic excursion (1.4 +/- 0.3 vs. 2.0 +/- 0.6 cm; P = 0.001), despite similar mean pulmonary artery pressure (49 +/- 10 vs. 47 +/- 12 mm Hg; P = 0.60). The 1- and 2-year survival estimates were 93% (95% confidence interval [CI], 73-98%) and 85% (95% CI, 65-94%), and 38% (95% CI, 14-63%) and 15% (95% CI, 2-39%) for normonatremic and hyponatremic subjects, respectively (log-rank chi(2) = 25.19, P < 0.001). The unadjusted risk of death (hazard ratio) in hyponatremic compared with normonatremic subjects was 10.16 (95% CI, 3.42-30.10, P < 0.001). Hyponatremia predicted outcome after adjusting for WHO class, diuretic use, as well as right atrial pressure and cardiac index.ConclusionsHyponatremia is strongly associated with right heart failure and poor survival in PAH.

Project description:Background/purposeAssociations between the disturbances in glucose homeostasis and prognosis in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) remain unclear. This study was conducted to investigate the clinical characteristics of disturbances in glucose homeostasis and their associations with 90-day mortality in patients with HBV-related ACLF.MethodsNinety-six patients with HBV-related ACLF without pre-existing diabetes were prospectively included. Glucose abnormalities were diagnosed based on fasting plasma glucose and oral glucose tolerance test results on admission and during follow-up. Homeostasis model assessment was used to establish insulin resistance (HOMA2-IR), insulin sensitivity (HOMA2-IS) and HOMA2-β-cell function (HOMA2-β). Multivariate Cox proportional hazards analysis was used to identify independent risk factors for death within 90 days after admission.ResultsAmong 96 patients with ACLF, 51 (53.1%) had diabetes, 29 (30.2%) had impaired glucose tolerance (IGT), and 17 (17.7%) had hypoglycemia. Patients with diabetes had significantly lower levels of HOMA2-β than did patients with normal glucose tolerance. Of 22 patients with diabetes or IGT and without anti-hyperglycemic treatment, 8 (36.4%) exhibited regression of their glucose metabolism disorders after a follow-up of 32.8 ± 28.8 days, and higher platelet levels were associated with regression. Twenty-five patients (25.0%) with ACLF died of liver failure within 90 days. Diabetes [odds ratio (OR) 3.601, 95% confidence interval (CI) 1.342-9.661] and age (OR 1.045, 95% CI 1.010-1.082) were the independent risk factors associated with mortality.ConclusionImpaired pancreatic β-cell function is related to diabetes development, and diabetes is associated with high mortality in patients with chronic HBV-related ACLF.

Project description:Background and aimPeriostin is a protein from the Fascilin family. It is commonly present in normal tissues and is responsible for cell adhesion. Evidence has emerged showing that changes in periostin expression play an important role in tumor initiation, development, and progression. This study aims to investigate the effect of periostin in gastric cancer (GC) patients who underwent gastrectomy. Seven hundred and forty-seven GC patients who underwent gastrectomy between December 2006 and July 2011 were included in this study.MethodsSeven hundred and forty-seven cancer tissues and 70 paired adjacent normal tissues were collected. Periostin expression was evaluated by immunohistochemistry. The Gene Expression Omnibus database was used to study the association between the mRNA level and patient's overall survival. The tumor microenvironment was also studied.ResultsPeriostin expression in stroma was downregulated in tumor tissues but it was upregulated in the epithelial cells. After dividing the tissues according to the Lauren Classification, we found that periostin expression in stroma and epithelial cells was higher in intestinal type than in diffuse type (P<0.001 and P=0.010, respectively). Periostin was an independent predictor of lymph node (LN) metastasis in GC patients. The study of CD163(+) tumor-associated macrophages (TAMs) revealed that in diffuse type GC, periostin expression was associated with CD163(+) TAMs.ConclusionWe found that the periostin expression can predict LN metastasis in patients undergoing curative gastrectomy. Intestinal type GC patients with high periostin level had both a favorable survival and lesser LN metastasis.
