title: Efficacy of lower than standard doses of pancreatic enzyme supplementation therapy during acid inhibition in patients with pancreatic exocrine insufficiency.
abstract: OBJECTIVE
  To compare, during strong acid inhibition with omeprazole, the effect of 2 different doses of an enteric-coated pancreatic enzyme preparation on fecal fat excretion and abdominal symptoms in patients with exocrine insufficiency due to chronic pancreatitis (CP).
  
  
  BACKGROUND
  Treatment with pancreatic enzymes reduces fecal fat excretion in patients with CP but is rather unsuccessful due to irreversible lipase inactivation at pH below 4.
  
  
  METHODS
  Sixteen patients with CP (3 women, 13 men; age 53+/-3 y) participated in this randomized double blind 2-way cross over study. Fecal fat excretion and fat intake were measured and abdominal symptoms (visual analog scales) were scored during a 2 weeks control period, during omeprazole 60 mg+pancreatic enzymes 10,000 Fédération Internationale Pharmaceutique IU lipase tid (treatment A) for 2 weeks and during omeprazole 60 mg+pancreatic enzymes, 20,000 Fédération Internationale Pharmaceutique IU lipase tid (treatment B) for 2 weeks.
  
  
  RESULTS
  During acid inhibition with enzyme supplementation fecal fat excretion was significantly (P<0.01) reduced compared with control: 18+/-7 and 18+/-5 g/24 h versus 36+/-8 g/24 h for treatment A, B, and control, respectively. Abdominal symptom score and general well being improved significantly (P<0.05) during treatments A and B versus control. No differences in fat excretion or symptoms scores between treatments A and B were observed.
  
  
  CONCLUSIONS
  During strong acid inhibition, lower than recommended oral doses of pancreatic enzymes are therapeutically effective with respect to fat absorption and symptom reduction.
