In different studies, it has been shown that the use of dipeptidyl peptidase-4 (DPP-4) inhibitors (DPP-4 inh) does not increase the risk of pancreatitis or pancreatic cancer. Although the number of studies involving clinical pancreatitis clinics is sufficient, the number of studies involving clinical non-pancreatitis hyperamylasemia is rare. The aim of the study was to investigate the relationship between DPP-4 inh usage and amylase and lipase increment without clinical pancreatitis symptoms.
Eighty-seven patients who met the inclusion criteria were enrolled. The patients were divided into 3 groups according to their use of saxagliptin, sitagliptin, or vildagliptin. All patients included in the study were receiving metformin at a dose of 2 g/day. Fasting blood glucose, postprandial blood glucose, HbA1C, serum creatinine, ALT, amylase, and lipase results were recorded at the beginning of treatment and at the end of 3 months.
There was an increase in all groups in terms of amylase and lipase values but there was no significant difference between the groups in terms of increase (p>0.05) There was no statistically significant increase in the saxagliptin and vildagliptin groups (p>0.05) when the baseline and 3-month values of lipase and amylase increase were examined. However, there was a statistically significant increase in amylase and lipase in the sitagliptin group (p<0.05).
The use of DPP-4 inh can increase amylase and lipase levels without clinical findings of acute pancreatitis in the patient. DPP-4 inh should be used with caution in patients at risk for pancreatitis and pancreatic cancer. Patients using DPP-4 inh, especially sitagliptin, should be evaluated carefully for pancreatitis risk factors.
