ABSTRACT The aetiology of acute pancreatitis (AP) is complex, and many risk factors for AP are shared by patients with type 2 diabetes mellitus (T2DM). However, few have assessed risk factors for AP specifically in T2DM patients.
Patients in the General Practice Research Database (2 984 755, 5.0% with T2DM) were used to estimate incidence of AP for T2DM relative to non-diabetes, adjusting for prior pancreatitis, gallbladder disease, obesity, smoking and alcohol use. Multivariate Cox regression analysis adjusting for risk factors and Charlson comorbidity index (CCI) was used to estimate hazard ratios (HR) with 95% confidence intervals (CI).
Between 2003 and 2007, 301 of 148 903 patients with T2DM and 2434 of almost 3 million patients without diabetes developed AP. Patients with T2DM had higher risk for AP compared with patients without diabetes (crude HR: 2.89, 95% CI: 2.56-3.27). Patients with T2DM had significantly higher rates of prior alcohol and tobacco exposure (44.2 and 61.9% vs. 34.1 and 35.9%, p < 0.001) and of comorbid conditions (14.7% with CCI > or =1 vs. 4.3%, p < 0.001). Histories of obesity, pancreatitis, gallbladder disease, smoking or alcohol use were significant predictors of AP. After adjusting for these factors, age, gender and comorbidities, the risk of developing AP remained elevated in patients with T2DM (adjusted HR: 1.49, 95% CI: 1.31-1.70).
After adjusting for risk factors, patients with T2DM had an elevated risk of AP compared with patients without diabetes. Physicians should be aware of the increased risk in patients with T2DM, particularly in those with prior pancreatitis.

    Article: The safety of incretin-based therapies--review of the scientific evidence.

    ABSTRACT: Antidiabetic therapies based on potentiation of incretin action are now widely used; however, understanding of their long-term safety remains incomplete. We searched articles in PubMed for data assessing the safety of incretin-based therapies. Three major areas of interest are reviewed: incretin action in the cardiovascular system, pancreatitis, and cancer. Incretin therapies reduce weight gain, minimize hypoglycemia, decrease inflammation, and are cardioprotective in preclinical studies. However, data permitting conclusions about whether incretin therapies modify the development of cardiovascular events in humans are not available. Case reports link incretin therapies to pancreatitis, but retrospective case control studies do not associate pancreatitis with glucagon-like peptide-1 receptor (GLP-1R) agonists or dipeptidyl peptidase-4 inhibitors. Preclinical studies of pancreatitis have yielded conflicting results, and mechanisms linking incretin receptor activation to pancreatic inflammation have not yet been forthcoming. GLP-1R activation promotes C-cell hyperplasia and medullary thyroid cancer in rodents; however, long-term clinical studies of sufficient size and duration to permit conclusions regarding cancer and incretin therapeutics have not yet been completed. The available data on incretin action and incidence of cardiovascular events, pancreatitis, or cancer are not yet sufficient or robust enough to permit firm conclusions regarding associations with incretin-based therapies in humans with diabetes. The forthcoming results of long-term cardiovascular safety studies should provide more conclusive information about the safety of GLP-1R agonists and dipeptidyl peptidase-4 inhibitors in diabetic patients.

    Article: Antidopaminergic drugs and acute pancreatitis: a population-based study.

    ABSTRACT: To evaluate the suggested association between antidopaminergic drugs and acute pancreatitis. A large population-based nested case-control study. Swedish nationwide study from 2006 to 2008. The Patient Register was used to identify 6161 cases of acute pancreatitis. The 61 637 control subjects were randomly selected from the Register of the Total Population by frequency-based density sampling, matched for age, sex and calendar year. Exposure data were extracted from the Prescribed Drug Register. Antidopaminergic drugs were grouped into antiemetic/anxiolytic and other antipsychotics. Current use of antidopaminergic drugs was defined as filling a prescription 1-114 days before index date, while previous use was 115 days to 3.5 years before index date. Cases were defined as being diagnosed as having acute pancreatitis. ORs and 95% CIs were calculated using unconditional logistic regression. The unadjusted OR indicated an increased risk of acute pancreatitis among current users of antiemetic/anxiolytics (OR 1.9, 95% CI 1.4 to 2.6), but not in the multivariable model adjusting for alcohol-related comorbidity, chronic obstructive lung disease, ischaemic heart disease, obesity, diabetes, opioid use, gallstone disease, educational level, marital status and number of concomitant medications (OR 0.9, 95% CI 0.6 to 1.2). Similarly, among current users of other antipsychotics, the unadjusted OR was 1.4 (95% CI 1.1 to 1.6), while the adjusted OR was 0.8 (95% CI 0.6 to 0.9). Results regarding previous use of antidopaminergic drugs followed a similar risk pattern as for current use. The lack of association between antidopaminergic drugs and acute pancreatitis after adjustment for confounding factors in this study suggests that the previously reported positive associations might be explained by confounding.
