Type 2 Diabetes Mellitus in Inflammatory Bowel Disease Patients: A Case-Control Study Through a Long Follow-Up Period.

The characterization of patients with inflammatory bowel disease (IBD) and type 2 diabetes mellitus (T2DM) as a new group has not been well detailed. This study aimed to evaluate the impact of T2DM on IBD progression and analyze the prevalence of steatotic liver disease and liver damage in these patients. Through a retrospective case-control study, we compared severe IBD occurrence in patients with both IBD-T2DM (cases) versus those with IBD alone (controls).

Associations Between Polymorphisms of Genes Related to Vitamin D Pathway and the Response to Vedolizumab and Ustekinumab in Inflammatory Bowel Disease.

: Vitamin D (VD) has immunoregulatory properties, generating interest in its potential to influence therapeutic outcomes in inflammatory bowel disease (IBD), other than affecting the expression of genes encoding enzymes and transporters involved in drug metabolism and transport. This study investigated VD-related single nucleotide polymorphisms (SNPs) as predictors of clinical responses in patients with Crohn's disease (CD) and ulcerative colitis (UC) treated with vedolizumab (VDZ) or ustekinumab (UST) after 3 (T3) and 12 months (T12), as well as the achievement of fecal calprotectin (FC) levels < 250 mg/kg, a marker of mucosal healing. : In this prospective study, 103 patients (67 CD, 36 UC) were enrolled, 40 receiving VDZ and 63 receiving UST.
