About EPI in Patients With CF
EPI can make life with CF even more difficult for patients and their caregivers2
Left untreated, EPI can compromise a growing child in many ways2
- Malabsorption leading to vitamin and nutrient deficiencies
- Impaired height and weight


According to the Cystic Fibrosis Foundation Guidelines3:
- The dangers of nutritional deficiency and negative consequences of eating associated with abdominal symptoms argue strongly in favor of proactive treatment
Early diagnosis and treatment of EPI can help patients absorb the nutrients they need4,5
EPI may cause the following symptoms2,6,7:
- Abdominal pain
- Bloating
- Excessive flatulence
- Frequent stools
- Nausea
- Malaise
- Diarrhea
- Steatorrhea
Poor nutritional status associated with untreated EPI may lead to poorer outcomes in patients with CF8
Effective management of EPI depends on9:

Pancreatic enzyme replacement therapy, such as ZENPEP®

Dietary modifications

Regular nutritional assessment as a component of routine care

The Cystic Fibrosis Foundation states that patients with laboratory evidence of EPI should be started on PERT even in the absence of signs of fat malabsorption.3
CF=cystic fibrosis; EPI=exocrine pancreatic insufficiency; PERT=pancreatic enzyme replacement therapy.
