title: No effect of long-term treatment with pancreatic extract on recurrent abdominal pain in patients with chronic pancreatitis.
abstract: BACKGROUND
  This study was aimed to investigate the effect of long-term treatment with high-protease pancreatic extract on the recurrent abdominal pain of patients with chronic pancreatitis.
  
  
  METHODS
  Twenty-six patients with a firm diagnosis of chronic pancreatitis and a pattern of recurrent pain were recruited and randomly assigned to treatment with pancreatic extract (Pancrex-Duo capsules, each containing 34,375 USP units of protease in enteric-coated microspheres) or placebo, at a dose of four capsules four times daily, for 4 months. At the end of the first period patients were switched to the other medication for the next 4 months. Four patients did not complete the study because of unbearable recurring pain or inadequate compliance with treatment. The other 22 patients daily recorded the presence, intensity, and duration of pain and the consumption of analgesics, for 8 months.
  
  
  RESULTS
  No difference was found when intraindividual records during placebo and extract treatment periods were compared. Conversely, in the second 4 months of follow-up, regardless of the treatment given in the first period, there was a significant reduction in the cumulative pain score (median, 95; range, 0-1005, versus 134; 0-972; p < 0.05), in the number of days (8; 0-132, versus 13; 0-126; p < 0.02) and hours (54; 0-680, versus 80; 0-602; p < 0.05) of pain, and in the analgesic consumption score (0; 0-22, versus 12; 0-44; p = 0.02).
  
  
  CONCLUSIONS
  Chronic supplementation with pancreatic extract is not beneficial in the management of recurrent pain in patients with chronic pancreatitis.
