1Associations of sense of coherence with psychological distress and quality of life in inflammatory bowel disease显示文摘AIM:To investigate the relationship between sense of coherence,psychological distress and health related quality of life in inflammatory bowel disease(IBD).METHODS:This cross-sectional study enrolled a consecutive sample of 147 IBD(aged 45.1 ± 14.1 years; 57.1% female) patients recruited from a tertiary gastroenterology service.Sixty-four participants met diagnostic criteria for Crohn's disease,while eightythree patients had ulcerative colitis.Socio-demographic data(education,age,race,gender,gross monthly income and marital status),disease-related variables(illness activity,relapse rate in past 2 years,history of surgery and time since diagnosis),sense of coherence(Antonovsky's SOC scale),psychological distress symptoms(Hospital Anxiety and Depression Scale) and health-related quality of life(HRQo L; WHOQOLBref) were assessed.Hierarchical multiple regression analyses were performed to identify factors that are independently associated with psychological distress and HRQo L in patients with IBD and to provide indications for possible moderating or mediating effects.In addition,formal moderation and mediation analyses(Sobel tests) were performed to confirm potential moderators/mediators of the relationship between SOC,psychological distress symptoms and HRQoL.RESULTS:Lower SOC scores(std beta=-0.504; P < 0.001),female gender(std beta = 0.176; P = 0.021) and White race(std beta = 0.164; P = 0.033) were independently associated with higher levels of depressive symptoms,while lower levels of SOC(std beta =-0.438; P < 0.001) and higher relapse rate(std beta = 0.161; P = 0.033) were independently associated with more severe anxiety symptoms.A significant interaction between time since diagnosis and SOC was found with regard to the severity of depressive or anxiety symptoms,as the interaction term(time since diagnosis X SOC) had beta coefficients of-0.191(P = 0.009) and-0.172(P = 0.026),respectively.Lower levels of anxiety symptoms(std beta =-0.369; P < 0.001),higher levels of SOC(std beta = 0.231; P = 0.016) and non-White race(std beta =-0.229; P = 0.006),i.e.,mixed-race,which represented the reference category,were independently associated with higher levels of overall HRQoL.Anxiety symptoms were the most potent independent correlate of most aspects of HRQoL.In addition,anxiety mediated the association between SOC and satisfaction with health,as well as its relationship with physical,mental,and social relations HRQo L.Depressive symptoms also mediated the association between SOC and mental HRQoL.CONCLUSION:Our data indicated that SOC is an important construct,as it influences psychological distress and has significant albeit indirect effects on several HRQoL domains in IBD.Thiago H Freitas Elias Andreoulakis Gilberto S Alves Hesley LL Miranda Lúcia LBC Braga Thomas Hyphantis André F Carvalho 2015World Journal of Gastroenterology2015,21,21:10
2Dietary and metabolomic determinants of relapse in ulcerative colitis patients: A pilot prospective cohort study显示文摘AIM To identify demographic, clinical, metabolomic, and lifestyle related predictors of relapse in adult ulcerative colitis(UC) patients.METHODS In this prospective pilot study, UC patients in clinical remission were recruited and followed-up at 12 mo to assess a clinical relapse, or not. At baseline information on demographic and clinical parameters was collected. Serum and urine samples were collected for analysis of metabolomic assays using a combined direct infusion/liquid chromatography tandem mass spectrometry and nuclear magnetic resolution spectroscopy. Stool samples were also collected to measure fecal calprotectin(FCP). Dietary assessment was performed using a validated self-administered food frequency questionnaire. RESULTS Twenty patients were included(mean age: 42.7 ± 14.8 years, females: 55%). Seven patients(35%) experienced a clinical relapse during the follow-up period. While 6 patients(66.7%) with normal body weight developed a clinical relapse, 1 UC patient(9.1%) who was overweight/obese relapsed during the follow-up(P = 0.02). At baseline, poultry intake was significantly higher in patients who were still in remission during follow-up(0.9 oz vs 0.2 oz, P = 0.002). Five patients(71.4%) with FCP > 150 μg/g and 2 patients(15.4%) with normal FCP(≤ 150 μg/g) at baseline relapsed during the follow-up(P = 0.02). Interestingly, baseline urinary and serum metabolomic profiling of UC patients with or without clinical relapse within 12 mo showed a significant difference. The most important metabolites that were responsible for this discrimination were trans-aconitate, cystine and acetamide in urine, and 3-hydroxybutyrate, acetoacetate and acetone in serum. CONCLUSION A combination of baseline dietary intake, fecal calprotectin, and metabolomic factors are associated with risk of UC clinical relapse within 12 mo.Ammar Hassanzadeh Keshtel iFloris F van den Brand Karen L Madsen Rupasri Mandal Rosica ValchevaKaren I Kroeker Beomsoo Han Rhonda C Bell Janis Cole Thomas Hoevers David S Wishart Richard N Fedorak Levinus A Dieleman 2017World Journal of Gastroenterology2017,23,21:9
3Hepatitis B virus mutations potentially conferring adefovir/ tenofovir resistance in treatment-naive patients显示文摘Anti-hepatitis B virus(HBV)therapy leads to the emer- gence of mutant viral strains during the treatment of chronic hepatitis B with nucleos(t)ides analogues. The existence of HBV variants with primary antiviral resistance may be important for treatment choice. We studied two patients with chronic HBV infection by sequencing the HBV polymerase gene.They had adefovir-and tenofovir-related mutations in the viral polymerase,although they had never been treated. These mutations were rtV214A/rtN238T in one patient and rtA194T in the other.Thus,mutations in untreated patients deserve cautious surveillance.These data indicate that mutations that can theoretically confer adefovir or tenofovir resistance may emerge in treatmentnaive patients.Rebecca Pastor Franois Habersetzer Samira Fafi-Kremer Michel Doffoёl Thomas F Baumert Jean-Pierre Gut Franoise Stoll-Keller Evelyne Schvoerer 2009World Journal of Gastroenterology2009,15,6:6

5Neutralizing antibodies in hepatitis C virus infection显示文摘Hepatitis C virus (HCV) is a major cause of hepatitis world-wide. The majority of infected individuals develop chronic hepatitis which can then progress to liver cirrhosis and hepatocellular carcinoma. Spontaneous viral clearance occurs in about 20%-30% of acutely infected individuals and results in resolution of infection without sequaelae. Both viral and host factors appear to play an important role for resolution of acute infection. A large body of evidence suggests that a strong, multispecific and long-lasting cellular immune response appears to be important for control of viral infection in acute hepatitis C. Due too the lack of convenient neutralization assays, the impact of neutralizing responses for control of viral infection had been less defined. In recent years, the development of robust tissue culture model systems for HCV entry and infection has finally allowed study of antibody-mediated neutralization and to gain further insights into viral targets of host neutralizing responses. In addition, detailed analysis of antibody-mediated neutralization in individual patients as well as cohorts with well defined viral isolates has enabled the study of neutralizing responses in the course of HCV infection and characterization of the impact of neutralizing antibodiesfor control of viral infection. This review will summarize recent progress in the understanding of the molecular mechanisms of antibody-mediated neutralization and its impact for HCV pathogenesis.Mirjam B Zeisel Samira Fafi-Kremer Isabel Fofana Heidi Barth Franoise Stoll-Keller Michel Doffo■l Thomas F Baumert 2007World Journal of Gastroenterology2007,13,36:3
