Overview

Xavier Calvet is affiliated with the Autonomous University of Barcelona in Spain and has established a significant research presence primarily in the medical sciences, with a prolific output in the fields of medicine and biochemistry, genetics, and molecular biology. Their work spans several specialized subfields, including genetics, surgery, epidemiology, immunology, and gastroenterology.

The scientific interests of Xavier Calvet concentrate chiefly on topics related to inflammatory intestinal conditions and gastrointestinal diseases. Key research themes include inflammatory bowel disease, microscopic colitis, Helicobacter pylori-related gastroenterology studies, gastric cancer management and outcomes, eosinophilic esophagitis, diverticular disease and its complications, as well as biosimilars and bioanalytical methods.

Xavier Calvet's recent academic contributions feature publications in prominent journals, demonstrating focus on therapies and clinical management strategies for inflammatory bowel diseases. Noteworthy recent papers include:

  • Ustekinumab versus adalimumab for induction and maintenance therapy in biologic-naive patients with moderately to severely active Crohn's disease: a multicentre, randomised, double-blind, parallel-group, phase 3b trial (2022, The Lancet)
  • Etrolizumab versus infliximab for the treatment of moderately to severely active ulcerative colitis (GARDENIA): a randomised, double-blind, double-dummy, phase 3 study (2021, The Lancet Gastroenterology & Hepatology)
  • Incidence, Clinical Characteristics and Management of Inflammatory Bowel Disease in Spain: Large-Scale Epidemiological Study (2021, Journal of Clinical Medicine)
  • Effectiveness and Safety of Ustekinumab in Ulcerative Colitis: Real-world Evidence from the ENEIDA Registry (2021, Journal of Crohn's and Colitis)
  • Real-world long-term effectiveness of ustekinumab in Crohn's disease: results from the ENEIDA registry (2020, Alimentary Pharmacology & Therapeutics)

Collaborations have been a significant aspect of Xavier Calvet's research output. Frequent co-authors include Javier P. Gisbert, Eugeni Domènech, Ana Gutiérrez, Montserrat Rivero, and Manuel Barreiro-de Acosta, reflecting an extensive network within the gastroenterology and inflammatory bowel disease research community.

Xavier Calvet has disseminated research results in several key publication venues, notably:

  • Journal of Crohn's and Colitis
  • Gastroenterología y Hepatología
  • Journal of Clinical Medicine
  • Gastroenterología y Hepatología (English Edition)
  • Endoscopy

The scope of their work reflects an interdisciplinary approach, incorporating clinical, genetic, and molecular biological perspectives to advance understanding and treatment of gastrointestinal disorders. This multidisciplinary focus is evident in the diversity of main fields and subfields associated with Calvet's publications.
