Description

Summary

A series of N-of-1 trials will be used to determine the effectiveness of a specific carbohydrate diet (SCD) versus a modified SCD in patients in reducing symptoms and inflammatory burden at both the individual and population level. This is a three-year study. The study staff will recruit 120 patients (goal sample size of 100, accounting for attrition) across up to 12 sites in patients aged 7-18 with mild to moderate disease activity.

  • Age 7-18 years
  • Enrolled in the ImproveCareNow (ICN2) registry
  • Evidence of acute inflammation and/or elevated acute phase reactant as measured by Fecal calprotectin 1.5 times the upper limit of normal, Lactoferrin 1.5 times the upper limit of normal, CRP 1.15 times the upper limit of normal, or ESR 1.15 times the upper limit of normal (based on local reference ranges) obtained within 8 weeks of enrollment.
  • Potential participants who are close to meeting one of the acute inflammation and/or elevated acute phase reactant markers and who meet all other study criteria will be considered for study participation on a case by case basis by the investigative study team in consultation with the patient's primary gastroenterologist.
