Study Summary

Chronic abdominal pain is extremely common in individuals with Cystic Fibrosis (CF). Therapy for chronic abdominal pain is very limited and generally consists of osmotic laxatives or drugs that are used to treat irritable bowel syndrome (IBS), most of which are off-label and not proven to be effective for CF patients. Abdominal pain negatively impacts the quality of life (QOL). With the development of novel therapies for CF, life expectancy has significantly increased. There is, therefore, a critical need to identify treatment pathways for chronic abdominal pain in children with CF. In humans, abdominal pain is modulated by the vagus nerve. Stimulation of the vagus nerve has been suggested to reduce visceral sensitivity and abdominal pain. IB-stim is the Percutaneous Electrical Nerve Field Stimulation (PENS) device. It is a non-invasive, outpatient therapy. PENFS has been shown to be efficacious in pediatric patients with abdominal pain. The FDA has cleared and classified this device as class II, suggesting minimal to moderate risk. There is increasing evidence of intestinal inflammation in patients with CF, which could help explain the GI symptoms and differentiate from IBS. Studies have reported increased inflammation in the intestines using fecal calprotectin. With the implementation of this study, we hypothesize that the IB -Stim device will reduce their overall GI inflammation and abdominal pain.
