Overview

Brief Summary

The purpose of this research is to determine if an investigational device called the 13C-Spirulina Gastric Emptying Breath Test (GEBT), can accurately diagnose gastroparesis (delayed emptying of the stomach) in patients with Cystic Fibrosis (CF).

Eligibility Criteria

Ages
4 Years to — (Child, Adult, Older Adult)
Sex
All
Accepts Healthy Volunteers
Yes

Inclusion Criteria

  • Patients age 4 years\* and above with a genetically confirmed diagnosis of CF (\*This age was chosen as patients younger than 4 years rarely undergo GES)
  • Actively being followed at the University of Miami CF Center (i.e. seen within the past 5 years at a University of Miami pediatric or adult pulmonology clinic)

Exclusion Criteria

  • History of abdominal surgeries involving gastrointestinal luminal resection (i.e. small bowel or colonic resection that increases risk of post-operative strictures or narrowing of the lumen). Nissen fundoplication, gastrostomy tube placement, gynecologic surgeries, appendectomy, and/or cholecystectomy are not excluded.
  • Gastrointestinal comorbidities that impact absorption such as Inflammatory Bowel Disease and Celiac Disease
  • Known hypersensitivity to Spirulina, egg, milk or wheat allergens
  • Patients not able to consume at least 50% of a standard test meal
  • Pregnant women
  • Adults unable to consent
  • Prisoners

Outcomes

Primary Outcomes

Rate of gastric emptying

Time Frame: 4 hours

The kPCD value (13CO2 excretion rate) at any time t, is proportional to the rate of gastric emptying. Increasing kPCD values represent increasing rates of gastric emptying.

Secondary Outcomes

  • Rate of gastric emptying over time(6 months)
