| 1 | Overview of cytokines and nitric oxide involvement in immuno-pathogenesis of inflammatory bowel diseases显示文摘Inflammatory bowel diseases(IBDs), including Crohn's disease and ulcerative colitis are complex disorders with undetermined etiology. Several hypotheses suggest that IBDs result from an abnormal immune response against endogenous flora and luminal antigens in genetically susceptible individuals. The dysfunction of the mucosal immune response is implicated in the pathogenesis of IBD. The balance between pro-inflammatory cytokines [tumor necrosis factor(TNF)-α, interleukin(IL)-1b, IL-8, and IL-17A], anti-inflammatory cytokines(IL-4 and IL-13), and immunoregulatory cytokines(IL-10 and transforming growth factors b) is disturbed. Moreover, evidence from animal and clinical studies demonstrate a positive correlation between an increased concentration of nitric oxide(NO) and the severity of the disease. Interestingly, proinflammatory cytokines are involved in the up-regulation of inducible oxide synthase(iN OS) expression in IBD. However, anti-inflammatory and immunoregulatory cytokines are responsible for the negative regulation of iN OS. A positive correlation between NO production and increased pro-inflammatory cytokine levels(TNF-α, IL-6, IL-17, IL-12, and interferon-γ) were reported in patients with IBD. This review focuses on the role of cytokines in intestinal inflammation and their relationship with NO in IBD. | Imene Soufli Ryma Toumi Hayet Rafa Chafia Touil-Boukoffa | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，3： | 30 |
| 2 | Prognostic significance of hepatic encephalopathy in patients with cirrhosis treated with current standards of care显示文摘BACKGROUND Hepatic encephalopathy(HE)is a reversible neuropsychiatric complication of liver cirrhosis and occurs in up to 50%of cirrhotic patients.Studies examining the prognostic significance of HE are limited despite the high prevalence in cirrhosis.AIM To define the clinical outcomes of patients after an episode of HE treated with current standards-of-care.METHODS All patients hospitalised with HE requiring Rifaximin to 3 tertiary centres over46-mo(2012–2016)were identified via pharmacy dispensing records.Patients with hepatocellular carcinoma and those prescribed Rifaximin prior to admission were excluded.Medical records were reviewed to determine baseline characteristics and survival.The Kaplan-Meier method was used to calculate survival probability.Univariate survival analysis was performed with variables reaching statistical significance included in a multivariate analysis.The primary outcome was 12-mo mortality following commencement of Rifaximin.RESULTS188 patients were included.Median age was 57 years(IQR 50-65),71%were male and median model for end stage liver disease and Child Pugh scores were 25(IQR 18-31)and 11(IQR 9-12)respectively.The most common causes of cirrhosis were alcohol(62%),hepatitis C(31%)and non-alcoholic fatty liver disease(20%).A precipitating cause for HE was found in 92%patients with infection(43%),GI bleeding(16%),medication non-compliance(15%)and electrolyte imbalance(14%)the most common.During a mean follow up period of 12±13 mo 107(57%)patients died and 32(17%)received orthotopic liver transplantation.Themost common causes of death were decompensated chronic liver disease(57%)and sepsis(19%).The probability of survival was 44%and 35%at 12-and 24-mo respectively.At multivariate analysis a model for end stage liver disease>15 and international normalised ratio reached statistical significance in predicting mortality.CONCLUSION Despite advances made in the management of HE patients continue to have poor survival.Thus,in all patients presenting with HE the appropriateness of orthotopic liver transplantation should be considered. | Anuj Bohra Thomas Worland Samuel Hui Ryma Terbah Ann Farrell Marcus Robertson | 2020 | World Journal of Gastroenterology2020，26，18： | 4 |
