Effectiveness and safety outcomes after long-term (54 weeks) vedolizumab therapy for Crohn's disease: a prospective, real-world observational study including patient-reported outcomes (POLONEZ II).

Background: The Crohn's Disease (CD) Activity Index (CDAI), Inflammatory Bowel Disease (IBD) Questionnaire (IBDQ), and IBD-Fatigue (IBD-F) scale are useful patient-reported outcome (PRO) tools for assessing the treatment benefits of vedolizumab (VDZ) beyond clinical trial endpoints in patients with CD.

Objectives: To assess clinical response, clinical remission, steroid-free remission, changes from baseline for PROs, and safety in a real-world cohort of patients with moderate-to-severe active CD treated with VDZ.

Design: POLONEZ II was a multicenter, observational, prospective study across 10 Polish centers from April 2020 to October 2023 for 54 weeks in patients with CD eligible for reimbursed VDZ.

Into the dark of the black oesophagus.

Acute esophageal necrosis (AEN), known as black oesophagus or Gurvit's syndrome, is an extremely rare clinical syndrome. Patients usually present with life-threatening symptoms of upper gastrointestinal haemorrhage (70-90% of cases), as in this case report. Diagnosis of AEN is confirmed based on oesophagogastroduodenoscopy which reveals diffuse or patchy circumferential black necrotic oesophageal mucosa.

microRNAs and Other Serological Markers of Liver Fibrosis in Patients with Alcohol-Related Liver Cirrhosis.

: It is essential to identify novel non-invasive markers of liver fibrosis for clinical and scientific purposes. Thus, the goal of our survey was to assess the serological expression of selected microRNAs (miRNAs) in patients with alcohol-related liver cirrhosis (ALC) and to correlate them with other existing markers. : Two hundred and thirty-nine persons were enrolled in the study: one hundred and thirty-nine with ALC and one hundred healthy controls.

Neutrophil PAD4 Expression and Its Pivotal Role in Assessment of Alcohol-Related Liver Disease.

Neutrophils release neutrophil extracellular traps (NETs) as a defense strategy in response to broad-spectrum infections and sterile triggers. NETs consist of a DNA scaffold decorated with antimicrobial peptides (AMPs) and enzymatically active proteases, including peptidyl arginine deiminase type 4 (PAD4). Susceptibility to infections and inflammatory dysregulation are hallmarks of alcohol-related liver disease (ALD).

Hemochromatosis-How Not to Overlook and Properly Manage "Iron People"-A Review.

Hemochromatosis (HC) is the main genetic disorder of iron overload and is regarded as metal-related human toxicosis. HC may result from and rare non- gene mutations, causing hepcidin deficiency or, sporadically, hepcidin resistance. This review focuses on -related HC.
