    Objective: This study investigated how vildagliptin (a di-peptidyl peptidase 4 inhibitor) affects portal vein pressure and hepatosteatosis in patients with type 2 diabetes mellitus. Methods: This cross-sectional study evaluated the use of specific drugs for at least 3 months on two groups of type 2 diabetes mellitus cases. Group 1 used metformin and gliclazide, Group 2 used the same amounts of metformin and gliclazide, with the addition of vildagliptin. Using Doppler ultrasound, all cases were measured for portal vein flow velocity, portal vein flow and portal vein diameter. Degree of hepatosteatosis was also recorded. Results: A total of 97 patients completed the study. The study finished with 49 type 2 DM patients in Group1 (20 men, 29 women) and 48 patients in Group2 (20 men, 28 women. No significant difference was found in term of age, gender, BMI, HbA1c, mean arterial pressure, LDL-C, HDL-C or triglyceride levels in two groups. Portal vein flow velocity, portal vein flow volume, and portal vein diameter of all cases were measured by Doppler ultrasound in both groups. No significant difference was found between the groups (respectively p=0.92,p=0.60, p=0.92). There was no significant difference between groups regarding to ultrasonographic grading of hepatosteatosis Conclusion: Treating type 2 diabetes mellitus patients with vildagliptin for had no effect on portal vein hemodynamics and hepatosteatosis as assessed with Doppler ultrasound. Further long-term studies with better evaluation methods are needed to demonstrate any expected beneficial effect of vildagliptin on portal hemodynamics and hepatosteatosis.
