Clinical study of pancreatic diabetes

Objective To study the incidence and clinical profile of pancreatic diabetes among the patients of insulin dependent diabetes mellitus. Methods 75 patients with diabetes with onset before 40 years of age were taken for the study. Diabetes is diagnosed by using criteria of American Diabetes Association. Pancreatic diabetes is diagnosed by using modified Bajaj Criteria. Results In pancreatic diabetes the male:female ratio was 1.2:1. Age group of the patients ranged from 12-40 years. Mean age ± SD at onset of symptoms was 16. 2 ±2. 64 years. Jowar was the staple food in 96. 4% of cases. Mean age ± SD at onset of pain abdomen was 9 ± 1. 4 years. The mean age ± SD of interval between the onset of abdominal pain and onset of symptoms was 7.46 ±2.02 years. Abdominal pain and steatorrhoea were present in 92. 8% and 35. 7% of cases respectively. Plain X-ray abdomen showed pancreatic calculi in 50% cases. Ultrasonography of abdomen show's pancreatic calculi in all cases. Conclusion Pancreatic diabetes is common entity in diabetics who are less than 40 years old and constitutes 37.3% of the total diabetics below 40 years of age. While the age of onset of symptoms was comparatively earlier in type 1 diabetes abdominal pain, parotid gland enlargement, blue lips and steatorrhoea were more common in pancreatic diabetes. FBS, PPBS and daily insulin requirement are higher in pancreatic diabetes.
