Background: The goal was to investigate the correlations of peripheral blood Omentin-1 and leptin (LEP) levels with bone metabolism and plasma glucose in patients with type 2 diabetes mellitus (T2DM) complicated with oste-oporosis (OP).
Methods: One hundred patients with T2DM admitted from September 2019 to September 2021 were divided into group A (n = 36, OP with T-score ≤ -2.5), group B (n = 50, osteopenia with T-score between -1 and -2.5), and group C (n = 14, non-OP with T-score > -1) according to the values of bone mineral density (BMD). Thirty healthy adults physically examined in the same period were selected as group D. The levels of peripheral blood Omentin-1 and LEP, bone metabolism, and plasma glucose were compared among the four groups. The correlations of peripheral blood Omentin-1 and LEP levels with bone metabolism and plasma glucose were explored by Pearson’s analysis.
Results: In group A, the levels of Omentin-1 and LEP in peripheral blood were lowest, the serum levels of beta C-terminal cross-linked telopeptides of type I collagen (β-CTX) and osteocalcin (OCN) were highest, the serum level of total N-terminal propeptide of type I procollagen (tPINP) was lowest, and the levels of fasting plasma glucose (FPG), 2-hours postprandial plasma glucose (2hPG) and glycosylated hemoglobin A1c (HbA1c) were highest, se-quentially followed by those of group B, group C, and group D (p < 0.05). Omentin-1 and LEP in peripheral blood were negatively correlated with β-CTX, OCN, 2hPG, and HbA1c and positively correlated with tPINP and FPG (p < 0.05).
Conclusions: The expressions of Omentin-1 and LEP in peripheral blood have correlations with bone metabolism and plasma glucose in patients with T2DM complicated with OP.
