A few of the 41 statement recommendations:

  • 6. In patients with mild to moderate ileal and/or right colonic Crohn’s disease, we suggest oral budesonide beginning at 9 mg/day as first-line therapy to induce complete remission. GRADE: Conditional recommendation, low-quality evidence
  • 20. In patients with moderate to severe luminal Crohn’s disease with risk factors of poor prognosis, we recommend anti-TNF therapy (infliximab, adalimumab) as first-line therapy to induce complete remission. GRADE: Strong recommendation, moderate-quality evidence
  • 23. In patients with active Crohn’s disease, when starting anti-TNF therapy, we suggest it be combined with a thiopurine or methotrexate over monotherapy to improve pharmacokinetic parameters. GRADE: Conditional recommendation, very low-quality evidence for infliximab, very low-quality evidence for adalimumab
  • 29. We suggest against switching between anti-TNF therapies in patients who are doing well on anti-TNF therapy. GRADE: Conditional recommendation, low-quality evidence
  • 30. In patients with moderate to severe Crohn’s disease who fail to achieve complete remission with any of corticosteroids, thiopurines, methotrexate, or anti-TNF therapy, we recommend vedolizumab to induce complete remission. GRADE: Strong recommendation, moderate-quality evidence
  • 34. In patients with moderate to severe Crohn’s disease who fail to achieve complete remission with any of corticosteroids, thiopurines, methotrexate, or anti-TNF therapy, we recommend ustekinumab to induce complete remission. GRADE: Strong recommendation, moderate-quality evidence
  • 37-41: Authors against the use of probiotics, omega-3 fatty acids, marijuana, naltrexone and enteral nutrition/diet therapies.
