title: Diabetes due to exocrine pancreatic disease--a review of patients attending a hospital-based diabetes clinic.
abstract: BACKGROUND
  Diabetes secondary to underlying exocrine pancreatic disease is a specific, but heterogeneous, type of diabetes mellitus. Studies such as UKPDS and DCTT excluded patients with pancreatic diabetes, so there is a paucity of evidence regarding best clinical practice in this group.
  
  
  OBJECTIVE
  To characterize the clinical features of patients with diabetes secondary to underlying pancreatic disease attending general diabetes clinics in a single hospital.
  
  
  METHODS
  A cross-sectional observational cohort study, identifying patients with pancreatic diabetes from clinic letters and medical notes at the University Hospital of Wales, Cardiff, UK.
  
  
  RESULTS
  The notes of 38 patients with pancreatic diabetes were reviewed. Of these, six had pancreatic malignancy and the remainder had a range of benign disorders. The majority (29/38) had diabetes diagnosed at or shortly after the pancreatic diagnosis was made. There was a lack of consistency regarding initial hypoglycaemic therapy, with metformin alone being the most common initial therapy, but with 30/38 taking insulin within 12 months of diagnosis. Similarly, a broad range of insulin regimens were employed with twice daily pre-mixed insulin being most prevalent. Sixty-three percent of patients were prescribed lipid lowering therapy and 42% were taking anti-hypertensives. Glycaemic control, as estimated by the latest HbA1C, was no different in patients with pancreatic diabetes compared to the general clinic population and there were no reports of severe hypoglycaemia.
  
  
  CONCLUSIONS
  There is great variability in how patients with pancreatic diabetes are currently managed. Future clinical trials should specifically address this group.
