Abstract
BACKGROUND AND AIMS Exclusive enteral nutrition (EEN) is not routinely used as induction therapy for adults with active Crohn's Disease (CD). The aim of this study was to assess the effectiveness of EEN with oral polymeric formula as an adjunct for inducing clinical and biochemical remission in adults with active CD. METHODS We performed a retrospective analysis of data from January 2018 to September 2019 on all patients with active CD who commenced EEN. Primary endpoint was clinical remission (CDAI ≤150) or response (100-point decrease in CDAI) at 8 weeks. Secondary endpoint was achievement of biochemical remission (CRP ≤5 mg/L or faeces calprotectin ≤150 mcg/g) at 8 weeks in those whose baseline values were elevated. We also aimed to identify predictors of response to EEN therapy. RESULTS Sixty-six patients commenced EEN, 53/66 (80.3%) completed the prescribed EEN course. At 8 weeks, 42/66 (63.6%) patients achieved primary endpoint and secondary endpoint was achieved in 30/53 (56.6%) of patients. Patients receiving EEN for ≥ 6 weeks achieved primary (72% vs 47.8%, OR 2.8, p = 0.047, CI 0.97 -8.16) and secondary endpoint (67.6% vs 36.8%, OR 3.58, p = 0.035, CI 1.1- 11.63) more frequently when compared with patients who received EEN for <6 weeks. Nine patients reported adverse effects (4 nausea,3 diarrhoea,1 constipation and 1 abdominal pain), none of whom ceased therapy. CONCLUSION Polymeric EEN is well tolerated, safe and effective in inducing clinical and biochemical remission in adults with active CD. EEN duration of ≥ 6 weeks has better outcomes.
