The Metagenomic Composition and Effects of Fecal-Microbe-Derived Extracellular Vesicles on Intestinal Permeability Depend on the Patient's Disease.

The composition and impact of fecal-microbe-derived extracellular vesicles (EVs) present in different diseases has not been analyzed. We determined the metagenomic profiling of feces and fecal-microbe-derived EVs from healthy subjects and patients with different diseases (diarrhea, morbid obesity and Crohn's disease (CD)) and the effect of these fecal EVs on the cellular permeability of Caco-2 cells. The control group presented higher proportions of and and lower proportions of , and in EVs when compared with the feces from which these EVs were isolated.

Incidence, Clinical Characteristics and Management of Inflammatory Bowel Disease in Spain: Large-Scale Epidemiological Study.

(1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD-Crohn's disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)-during 2017 in Spain were included and were followed-up for 1 year.

Changes in the requirement for early surgery in inflammatory bowel disease in the era of biological agents.

Background And Aim: Biological therapies may be changing the natural history of inflammatory bowel diseases (IBDs), reducing the need for surgical intervention. We aimed to assess whether the availability of anti-TNF agents impacts the need for early surgery in Crohn's disease (CD) and ulcerative colitis (UC).

Methods: Retrospective, cohort study of patients diagnosed within a 6-year period before and after the licensing of anti-TNFs (1990-1995 and 2007-2012 for CD; 1995-2000 and 2007-2012 for UC) were identified in the ENEIDA Registry.

Effectiveness of adalimumab for the treatment of ulcerative colitis in clinical practice: comparison between anti-tumour necrosis factor-naïve and non-naïve patients.

Background: Ulcerative colitis (UC) treatment is focused to achieve mucosal healing, avoiding disease progression. The study aimed to evaluate the real-world effectiveness of adalimumab (ADA) in UC and to identify predictors of remission to ADA.

Methods: This cohort study used data from the ENEIDA registry.

Vascular ophthalmological side effects associated with antiviral therapy for chronic hepatitis C are related to vascular endothelial growth factor levels.

We have screened for the incidence of vascular ophthalmological side effects (VOSE) in chronic hepatitis C (CHC) patients undergoing pegylated interferon (peg-IFN) plus ribavirin (RBV) therapy and sought evidence for angiogenesis activation. Thirty-four CHC patients were prospectively evaluated (18 patients with 180 microg/week of peg-IFN-alpha2a plus 800mg/day of RBV and 16 with 1.5 microg/kg/week of peg-IFN-alpha2b plus 800-1,200mg/day of RBV).

Causality assessment in drug-induced hepatotoxicity.

Drugs are currently an important cause of liver disease, ranked as the most frequent reason for acute liver failure. Despite recent advances in knowledge of the mechanisms implicated in drug-induced hepatocellular damage and cholestasis, as well as the identification of several risk factors, the diagnosis of hepatotoxicity remains a difficult task because specific tests are not available. In a step-by-step approach, the incrimination of a drug in liver symptoms requires a high degree of suspicion on the part of the physician, temporal eligibility, awareness of the drug's hepatotoxic potential, the exclusion of alternative causes of liver damage, and the ability to detect the presence of subtle data that favour a toxic aetiology.
