Patients with different types of diabetes mellitus frequently show alterations in pancreatic morphology and exocrine function. PEI can therefore occur as a result of long-standing type 1 and type 2 diabetes.1,2

  • In a 2015 audit, 24% of patients with diabetes had abnormal stools (score 5 on the Bristol Stool Chart), steatorrhoea or unexplained weight loss3
  • 42% of symptomatic patients who provided a stool sample had FE-1 levels indicative of PEI3

One study examined the efficacy of Creon® in patients with tropical calculous pancreatitis, a form of chronic pancreatitis largely attributed to malnutrition that’s prevalent in India and other Afro-Asian countries in which patients present with abdominal pain, pancreatic calculi and insulin-resistant diabetes.4

After 6 months of Creon® treatment patients achieved better control of diabetes, improvement in abdominal symptoms and overall sense of well being.4 This included a significant reduction in post-prandial plasma glucose and glycosylated haemoglobin at six months vs. baseline.4

Furthermore, these patients showed significant improvements in PEI symptoms, including the following:4

Double-blind, multi-centre, prospective, 16-week study investigating the effects of Creon® on glucose metabolism and clinical symptoms in a group of 80 insulin-treated, diabetic patients with FE-1 <100 mcg/g. Patients received 4 x Creon® 10000 capsules (n = 39) or placebo (n = 41) taken three times a day with main meals, plus two or three snacks with 2 x Creon® 10000 capsules or placebo each day.

Patients with diabetes may have an increased risk of developing PEI, if PEI is diagnosed, these patients should be treated.5
