Abstract

Abstract: Background and Aims: Immunosuppressive therapy is routine for adults with complex active Crohn's disease (CD), however carries risks, particularly in the setting of sepsis. Exclusive enteral nutrition (EEN) is widely used in paediatric CD, yet efficacy data in adults are sparse. This study evaluated outcomes of EEN in adults with complex active CD. Methods: Between December 2016 and June 2018, 13 patients with complex active CD (range 20–74 years) managed at a single hospital received 2 or more weeks of EEN. Patients were offered EEN based on either malnutrition, contraindication to immunosuppression, or CD refractory to multiple therapies. Subjective and objective outcomes were recorded at 2 and 6 weeks and compared with baseline data. Results: Nine of 13 patients experienced subjective improvement in wellbeing. Objective improvements included nine CRP decrements (median = 87.7 mg/L, IQR = 70.6 mg/L), nine serum albumin increments (median = 7 g/L, IQR = 4 g/L), and six gained weight (median = 3.6 kg, IQR = 3.0 kg). All five patients with complex abscess resolved without surgery. One ileocolic fistula and one enterocutaneous fistula achieved resolution without surgery. One of two perianal fistulae cases resolved without surgery. Seven of 10 patients initially thought to need surgery avoided it due to disease resolution. Only one of the three patients who proceeded to surgery sustained a post-operative complication. There were no EEN-associated complications. Conclusions: In complex active CD, our real-world data show that EEN improves wellbeing, decreases inflammatory markers, leads to healthy weight gain, reduces need for surgical intervention, and reduces postoperative complications. Lay Summary: In complex active Crohn's disease, our real-world data show that entire enteral nutrition improves wellbeing, decreases inflammatory markers, leads to healthy weight gain, reduces need for surgical intervention, and reduces postoperative complications.
