AIM To characterize the gut bacterial microbiota of patients with primary sclerosing cholangitis(PSC) and ulcerative colitis(UC).METHODS Stool samples were collected and relevant clinical data obtained from 106 study participants, 43 PSC patients with(n = 32) or without(n = 11) concomitant inflammatory bowel disease, 32 UC patients, and 31 healthy controls. The V3 and V4 regions of the 16 S ribosomal RNA gene were sequenced on Illumina Mi Seq platform to cover low taxonomic levels. Data were further processed in QIIME employing Ma As Lin and LEf Se tools for analysis of the output data.RESULTS Microbial profiles in both PSC and UC were characterized by low bacterial diversity and significant change in global microbial composition. Rothia, Enterococcus, Streptococcus, Veillonella, and three other genera were markedly overrepresented in PSC regardless of concomitant inflammatory bowel disease(IBD). Rothia, Veillonella and Streptococcus were tracked to the species level to identify Rothia mucilaginosa, Streptococcus infantus, S. alactolyticus, and S. equi along with Veillonella parvula and V. dispar. PSC was further characterized by decreased abundance of Adlercreutzia equolifaciens and Prevotella copri. Decrease in genus Phascolarctobacterium was linked to presence of colonic inflammation regardless of IBD phenotype. Akkermansia muciniphila, Butyricicoccus pullicaecorum and Clostridium colinum were decreased in UC along with genus Roseburia. Low levels of serum albumin were significantly correlated with enrichment of order Actinomycetales.CONCLUSION PSC is associated with specific gut microbes independently of concomitant IBD and several bacterial taxa clearly distinguish IBD phenotypes(PSC-IBD and UC). 展开更多

Primary sclerosing cholangitis(PSC) is a disease of the biliary tract, which has been documented in the literature since 1867. This disease has a strong predilection for affecting men and can be seen in individuals as young as 2 years of age. PSC has a strong associated with inflammatory bowel disease, more commonly with ulcerative colitis, and is also part of the clinical spectrum of Ig G4-related diseases. Smallduct PSC, a variant of PSC, also has an association with inflammatory bowel disease. The exact pathogenesis of PSC is not well understood at present, however, is likely a combination of a genetic predisposition with alteration of the molecular structure of the gut. Abnormal serum liver chemistry and presence of certain autoimmune markers are usually the first indicators leading to a diagnosis of PCS, however, these may often be normal in early stages of this disease. The diagnosis is made by cholangiography, which is now considered the gold standard. PSC is a known pre-malignant condition. Such patients have an increased risk of developing cholangiocarcinoma, gallbladder neoplasia, and colon cancer. Many new treatment modalities have emerged in the recent past, including anti-tumor necrosis factor-α and anti-integrins; however, liver transplantation is the only known cure for PSC. Despite past and present research, PSC remains an enigmatic biliary disease with few viable treatment options. 展开更多

AIM To assess the prevalence of a panel of serologic markers that reflect gut barrier dysfunction in a mixed cohort of pediatric and adult primary sclerosing cholangitis(PSC) patients.METHODS Sera of 67 PSC patients [median age(range): 32(5-79) years, concomitant IBD: 67% and cirrhosis: 20%] were assayed for the presence of antibodies against to F-actin(AAA Ig A/Ig G) and gliadin(AGA Ig A/Ig G)] and for serum level of intestinal fatty acid-binding protein(I-FABP) by ELISA. Markers of lipopolysaccharide(LPS) exposure [LPS binding protein(LBP)] and various antimicrobial antibodies [anti-OMP Plus Ig A and endotoxin core Ig A antibody(Endo CAb)] were also determined. Poor disease outcome was defined as orthotopic liver transplantation and/or liver-related death during the follow-up (median: 99(14-106) mo)One hundred and fifty-three healthy subjects(HCONT) and 172 ulcerative colitis(UC) patients were the controls. RESULTS A total of 28.4%, 28.0%, 9% and 20.9% of PSC patients were positive for AAA Ig A, AAA Ig G, AGA Ig A and AGA Ig G, respectively. Frequencies of AAA Ig A and AAA Ig G(P < 0.001, for both) and AGA Ig G(P = 0.01, for both) but not AGA Ig A were significantly higher compared to both of the HCONT and the UC groups. In survival analysis, AAA Ig A-positivity was revealed as an independent predictor of poor disease outcome after adjusting either for the presence of cirrhosis (HR = 5.15(1.27-20.86), P = 0.022 or for the Mayo risk score(HR = 4.24(0.99-18.21), P = 0.052)AAA Ig A-positivity was significantly associated with higher frequency of antimicrobial antibodies(P < 0.001 for Endo Cab Ig A and P = 0.012 for anti-OMP Plus Ig A) and higher level of the enterocyte damage marker(median I-FABPAAA Ig A pos vs neg: 365 vs 166 pg/m L, P = 0.011), but not with serum LBP level. CONCLUSION Presence of Ig A type AAA identified PSC patients with progressive disease. Moreover, it is associated with enhanced mucosal immune response to various microbial a 展开更多

AIM To investigate presence and extent of eosinophilic cholangitis(EC) as well as Ig G4-related disease in patients with indeterminate biliary stricture(IBS).METHODS All patients with diagnosis of sclerosing cholangitis(SC) and histopathological samples such as biopsies or surgical specimens at University Hospital Frankfurt from 2005-2015 were included. Histopathological diagnoses as well as further clinical course were reviewed. Tissue samples of patients without definite diagnosis after complete diagnostic work-up were reviewed regardingpresence of eosinophilic infiltration and Ig G4 positive plasma cells. Eosinophilic infiltration was as well assessed in a control group of liver transplant donors and patients with primary sclerosing cholangitis.RESULTS One hundred and thirty-five patients with SC were included. In 10/135 (13.5%) patients, no potential cause of IBS could be identified after complete diagnostic work-up and further clinical course. After histopathological review, a post-hoc diagnosis of EC was established in three patients resulting in a prevalence of 2.2% (3/135) of all patients with SC as well as 30%(3/10) of patients, where no cause of IBS was identified. 2/3 patients with post-hoc diagnosis of EC underwent surgical resection with suspicion for malignancy. Diagnosis of Ig G4-related cholangitis was observed in 7/135 patients (5.1%), whereas 3 cases were discovered in post-hoc analysis. 6/7 cases with Ig G4-related cholangitis (85.7%) presented with eosinophilic infiltration in addition to Ig G4 positive plasma cells. There was no patient with eosinophilic infiltration in the control group of liver transplant donors (n=27) and patients with primary sclerosing cholangitis(n = 14).CONCLUSION EC is an underdiagnosed benign etiology of SC and IBS, which has to be considered in differential diagnosis of IBS. 展开更多

Biliary strictures are caused by a heterogeneous group of benign and malignant conditions, each requiring a specific treatment approach. Management of biliary strictures often involves endoscopy either for definite treatment, as a bridge to surgery or for palliative purposes. Endoscopic treatment of various types of biliary strictures is not standardized and there are multiple areas of controversy regarding the best treatment options. These controversies are mainly due to lack of well-designed comparative studies to support a specific therapy. This paper reviews three common areas of controversy in the endoscopic management of biliary strictures. The areas discussed in this editorial include the role of biliary drainage in resectable malignant strictures and whether such drainage should be performed routinely prior to surgery, the best endoscopic palliation for unresectable hilar strictures and whether unilateral or bilateral stenting should be attempted, and the optimal endoscopic management for dominant strictures in patients with primary sclerosing cholangitis. The goal of this editorial is twofold. The first is to review the current literature on management of the aforementioned strictures and offer recommendations based on available evidence. The second goal is to highlight the gaps in our knowledge which in turn can encourage future research on these topics. 展开更多

Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI. 展开更多
