Improvements in anthropometric measures and gastrointestinal tolerance in patients with cystic fibrosis by using a digestive enzyme cartridge with overnight enteral nutrition

BACKGROUND: Patients with cystic fibrosis (CF) and pancreatic insufficiency are at risk for suboptimal fat absorption, inability to maintain weight, poor growth, and increased gastrointestinal (GI) symptoms due to malabsorption. Enteral nutrition (EN) is used to supplement caloric intake and requires pancreatic enzyme replacement for effective digestion. We evaluated the relationship between long‐term use of an in‐line digestive enzyme cartridge with EN and changes in anthropometric measures and GI symptoms in patients with CF. METHODS: This is a single‐center, retrospective case review of patients with CF using a digestive enzyme cartridge with EN. Data were collected from the patient medical records and included weight, height, body mass index, EN regimen, and reported GI symptoms. RESULTS: Thirteen pediatric and five adult patients with a mean age of 12.6 years used a digestive enzyme cartridge with EN for a period of 3–27 months. Most patients (n = 14) had been using oral digestive enzymes with EN before using the digestive enzyme cartridge, whereas four started from the onset of EN. The indications to convert from oral enzymes to the digestive enzyme cartridge included poor growth (72.2%) and poor tolerance of EN (69.2%). There was a reduction in reported GI symptoms after initiating use of the digestive enzyme cartridge. After 12 months of digestive cartridge use, there were improvements in anthropometrics. CONCLUSIONS: This real‐world experience with prolonged use of a digestive enzyme cartridge with EN demonstrated improved clinical outcomes and a reduction in GI symptoms in patients with CF.
