Results The RH-PAT and laboratory parameters, including 75 g oral glucose tolerance test, were measured at baseline and 3 months. Linagliptin reduced serum levels of glucose and insulin at 2 hours, and increased levels of active glucagon-like peptide-1 and high-molecular-weight adiponectin. Age-, sex-, and baseline-adjusted changes in logarithmic RH-PAT index (LnRHI) after 3 months were significant between groups (linagliptin, 0.135&plusmn;0.097; voglibose, -0.124&plusmn;0.091; P=0.047). In the linagliptin group, change in LnRHI was positively correlated with change in high-density lipoprotein cholesterol and negatively correlated with changes in both urine albumin-to-creatinine ratio and high-sensitivity C-reactive protein.
