Real-world experience of vedolizumab use in Colombian patients with inflammatory bowel disease-EXVEDOCOL.

Background: Real-world studies about the effectiveness and safety of vedolizumab (VDZ) in the treatment of inflammatory bowel disease (IBD) in Latin America are scarce. Our study describes the effectiveness and safety of VDZ in Colombian patients with IBD.

Methods: EXVEDOCOL (EXperience of VEDOlizumab in COLombia) was a retrospective, multicenter, observational study.

Clinical characteristics and treatment of perianal fistulising Crohn's disease in Colombia: Results of a multicentric registry.

Introduction: Perianal fistulizing Crohn's disease (CD) is a phenotype with a poor prognosis. There are no studies in our country. Our objective is to determine the clinical, sociodemographic and treatment characteristics of perianal fistulizing CD in a Colombian multicenter registry.

Clinical differentiation of inflammatory bowel disease (IBD) in Latin America and the Caribbean.

The aim of the present study was to describe the epidemiological and clinical characteristics of inflammatory bowel disease (IBD), including medical and surgical treatments, in several countries in Latin America and the Caribbean.IBD is recognized as a global health problem because its incidence and prevalence have increased significantly over the last few years.This multicenter retrospective cohort study included 4714 patients with IBD diagnosed from 9 countries in Latin America and the Caribbean: Colombia, Cuba, Dominican Republic, Ecuador, Mexico, Peru, Puerto Rico, Uruguay, and Venezuela.

Identification of peptides with high red blood cell and hepatocyte binding activity in the Plasmodium falciparum multi-stage invasion proteins: PfSPATR and MCP-1.

Plasmodium falciparum multi-stage proteins are involved in vital processes for parasite survival, which turns them into attractive targets for studies aimed at developing a fully effective antimalarial vaccine. MCP-1 and PfSPATR are both found in sporozoite and merozoite forms, and have been associated respectively with invasion of hepatocytes and red blood cells (RBCs). Binding assays with synthetic peptides derived from these two important proteins have enabled identifying those sequences binding with high specific activity (named High activity binding peptides-HABPs) to hepatoma-derived HepG2 cells and human RBCs.
