Comparison of biochemical parameters among DPP4 inhibitor users and other oral hypoglycaemic drug users: a cross-sectional study from Anuradhapura, Sri Lanka.

BACKGROUND

Higher efficacy of incretin-based therapies for type 2 diabetes mellitus has been reported from Asia. Pancreatitis and hepatitis have also been suspected to occur due to dipeptidyl peptidase-4 inhibitor (DPP4I) treatment. The present study aims at comparing selected biochemical parameters among DPP4 inhibitor users and other oral hypoglycaemic drug users.

METHODS

Patients were recruited from the State Pharmaceutical Corporation, Anuradhapura, Sri Lanka, for a comparative cross-sectional study. Two groups were involved: "DPP4I" user group (n = 63) and "other oral hypoglycaemic" user group (n = 126). Mann-Whitney U test was performed to find a significant difference (p < 0.05) in the distributions of HbA, pancreatic amylase, serum lipase, AST and ALT levels between the two groups.

RESULTS

Contradicting to previous Asian studies, distribution of HbA (p = 0.569) between anti-diabetic regimes with and without DPP4 inhibitors showed no significant difference. Also, amylase (p = 0.171), AST (p = 0.238) and ALT (p = 0.347) failed to show significance. However, lipase was significantly (p = 0.012) high in the DPP4I group.

CONCLUSION

The study showed a significantly higher lipase level among the DPP4I users in comparison to other oral hypoglycaemic drug users, and possible reasons were discussed.
