Abstract:
Objective To investigate the incidence of diabetes mellitus and risk factors for the disease in chronic pancreatitis (CP) patients.Methods A historical cohort study on subjects with painful CP who were admitted to hospital from Jan.1997 to July 2007 were conducted.A life-table method was used to estimate the cumulative probability of the development of diabetes mellitus once clinical onset of abdominal pain.Cox proportional-hazards model was used for multivariate analysis of the variables including age,sex,drinking and smoking habits,etiological factor,presence of pancreatic masses,pancreatic calcifications,measure of intervention,diarrhea,weight loss and degree of pain.Results Data were obtained from 354 patients (239 males,mean age at onset of pain (38.1±17.6) years;alcoholic origin 18.1%) with painful CP.The mean follow-up period was (45.2±32.9)months.The rate of diabetes mellitus in CP patients was 16.1%.There was a high incidence (29.8%)of diabetes mellitus 1 year before the episodes of abdominal pain.The cumulative risk of diabetes mellitus in subjects 5 and 10 years after the episodes of pain was 9.3% and 20.7%,respectively.Cox proportional-hazards model selected smoking (＞10 pack years) (hazard rate (HR)= 3.3),mild abdominal pain (HR=5.2),weight loss (HR = 2.6) and pancreatic calcifications (HR = 2.2) as variables identifying subjects with diabetes mellitus in patients with painful CP before they were performed therapeutic endoscopy or surgical intervention.Smoking (＞10 pack years) (HR = 3.0),weight loss (HR= 2.8) and distal pancreatectomy (HR =7.3) were identified with an increased risk of diabetes mellitus in these cases after they received therapeutic endoscopy or surgical intervention.Conclusion The risk factors of diabetes mellitus for CP appears to be independent of smoking (＞10 pack years),mild abdominal pain,weight loss,pancreatic calcifications and distal pancreatectomy.
