IBD Update -August 2020

S Jansson et al JPGN 2020; 71: 40-5. This retrospective study (1998-2008) showed that pediatric patients with extraintestinal manifestations (EIM) had more severe IBD course than patients with IBD without an EIM.  EIM often had a temporal relationship with a relapse of IBD as well. Of 333 patients, 14 had an EIM at diagnosis and 47 had an EIM develop during followup.

PA Olivera, JS Lasa et al. Gastroenterol 2020; 158: 1554-73. This systematic review and meta-analysis ultimately included 82 studies with 66,159 patients (including those with IBD and other immune-mediated diseases) exposed to a JAK inhibitor; two-thirds of studies were randomized controlled trials.  Key findings:

  • Incidence rates of serious infections, herpes zoster infection, malignancy, and major cardiovascular events were 2.81, 2.67, 0.89, and 0.48 per 100 person year respectively. After meta-analysis, the authors conclude that there is an increased risk of herpes zoster (RR 1.57), but all other adverse events were not increased among patients treated with JAK inhibitors
  • Mortality was not increased in those receiving JAK inhibitors compared to placebo

Loebenstein, JD Schulberg. Gastroenterol 2020; 158: 2069-71.  This case report describes a successful alternative anti-TNF rechallenge after infliximab induced Lupus in Crohn’s disease.  The authors note that in a previous study, 14 of 20 IBD patents with drug-induced lupus secondary to an anti-TNF agent were rechallenged with an alternative anti-TNF agent and 13/14 tolerated rechallenge without recurrent lupus (Inflamm Bowel Dise 2013; 19: 2778-86).
