JL Yang et al. Inflamm Bowel Dis 2023; 29: 735-743. Utilization of Colonoscopy Following Treatment Initiation in U.S. Commercially Insured Patients With Inflammatory Bowel Disease, 2013-2019

In this study with 39,734 commercially-insured initiators of IBD medications (18-64 year old), 34% had a colonoscopy by 12 months and 42% at 15 months. The authors state that “it is evident that patients without any colonoscopy during this interval are not being followed under an optimal long-term T2T (treat-to-target) paradigm.”

RS Dalal et al. Inflamm Bowel Dis 2023; 29: 830-833. Long-Term Outcomes After Ustekinumab Dose Intensification for Inflammatory Bowel Diseases

This retrospective study examined 123 patients with Crohn’s disease and 40 with ulcerative colitis who had dose intensification with ustekinumab (to either every 4 weeks, n=91, or every 6 weeks, n=72). Dose escalation was effective in both achieving and maintaining corticosteroid-free clinical remission for 61% of patients with Crohn’s disease and 40% with ulcerative colitis at 24 months; endoscopic remission was noted in 43% with Crohn’s disease and 55% with ulcerative colitis.

EV Loftus et al. Inflamm Bowel Dis 2023; 29: 744-751. Open Access! Clostridium difficile Infection in Patients with Ulcerative Colitis Treated with Tofacitinib in the Ulcerative Colitis Program 

Using data from multiple studies with 1157 patients, only 9 tofacitinib patients developed Clostridioides difficile infection (CDI) which was lower than the placebo group. CDI were all mild–moderate in severity and resolved with treatment in 8 patients. Six of 9 patients continued tofacitinib treatment without interruption. The low rate of infection was likely in part due to screening for CDI prior to treatment. In addition, “it is possible than the lower rates of CDI …may be due to better-controlled disease…, thus reducing susceptibility to infection.”

One clinical pearl in the discussion: “When considering treatment [for CDI], initial therapy with oral vancomycin should be considered instead of metronidazole, and treating for at least 21 days should also be considered [in patients with IBD due to]…lower rates of CDI recurrence.”
