OBJECTIVE: To assess the relationship between pancreatic enzyme therapy (PET) and the clinical outcomes of growth, abdominal pain, constipation, gassiness, and number of stools in cystic fibrosis (CF). STUDY DESIGN: Patients (n = 1215) >4 weeks of age from 33 Cystic Fibrosis Foundation accredited sites who had a sweat chloride >60 mmol/L or two CF-causing mutations were enrolled using a proportionate sampling strategy in a nonblinded study. Patients submitted a stool sample and completed a questionnaire. The study coordinator also completed a questionnaire for each patient. Enzyme dosing and growth, abdominal pain, gassiness, constipation, and number of stools were compared. RESULTS: Of the 1215 enrolled patients, 1131 (93.1%) were prescribed PET. Only 14.9% had pancreatic function assessed before enrolling in this study. Stool elastase-1 analysis identified 1074 (89%) patients as pancreatic insufficient (PI). There was no association between PET and the outcomes: growth, abdominal pain, gassiness, constipation, and number of stools. CONCLUSION: PET dose is not correlated with growth or gastrointestinal symptoms. More sensitive outcome measures of the effectiveness of PET in patients with CF are needed to guide treatment of PI.
