BACKGROUND: Pancreatic exocrine insufficiency is a common condition in patients with cystic fibrosis. Large amounts of pancreatic enzyme supplements are required to reduce malabsorption but patient compliance is not always optimal. AIMS: To compare patients' preference and the efficacy of two enteric coated microsphere preparations in patients with cystic fibrosis. PATIENTS: Patients with pancreatic exocrine insufficiency due to cystic fibrosis. METHODS: Patients were assigned to the crossover treatment with Creon or Pancrease for 1 week and then to the alternative treatment. Patients had to follow a fixed diet (at least 2 g fat/kg) and had to assume 1000 units lipase/g fat. The evaluation parameters were: patients' preference, acceptance of therapy, stool fat excretion, stool weight, gastrointestinal symptoms, and tolerance. RESULTS AND CONCLUSIONS: Of the 33/60 patients who expressed a preference for one of the two treatments, 30 preferred Creon while only 3 patients preferred Pancrease (p<0.001). No difference between the two treatments was observed regarding stool characteristics, gastrointestinal symptoms and tolerance. The mean number of capsules taken daily was reduced by 35% with Creon. The results of this study showed a preference in favour of Creon probably due to the reduction of daily capsule intake of 35%, supporting digestion as well as Pancrease.
