Prediabetes is often observed in patients with Metabolic Syndrome (MetS) and might be associated with metabolic and inflammatory alterations. Here, we investigated whether the inflammatory molecule osteopontin (OPN) might have a prognostic impact in a cohort of MetS patients (n=85) with baseline normal glycaemia or impaired fasting glucose (IFG) over one year of recommended pharmacological treatments and Mediterranean diet. Patients were then followed up for 12months with intermediate evaluation after 6months. At all time points, anthropometric and clinical data were recorded, alongside with haematological and biochemical profiles, including serum concentrations of OPN. As expected, Mediterranean diet improves glycaemic profile in patients with IFG. Baseline serum OPN failed to be associated with baseline anthropometric or biochemical variables. At baseline, higher levels of OPN were shown in patients with IFG as compared to normal glycaemia. Two distinct subgroups of patients in whom OPN decreased or remained stable/increased at follow-up were identified. When higher serum OPN levels were observed at baseline, greater reduction was observed at 1-year follow-up. Reduction in circulating OPN levels was associated with metabolic improvement in terms of blood pressure, LDL-c, HDL-c, and glycaemia. At both univariate and adjusted logistic regression analyses, serum OPN emerged as an independent predictor of glycaemic profile improvement at 1-year follow-up (adjOR 1.05 [1.00-1.10]; P=.041). In conclusion, pharmacological and dietetic interventions improved glycaemic profile in patients with MetS. In particular, glycaemic improvement was demonstrated in patients who also reduce circulating OPN levels. Higher OPN levels at baseline predict normalization of glycaemic profile.

Abstract

Prediabetes is often observed in patients with Metabolic Syndrome (MetS) and might be associated with metabolic and inflammatory alterations. Here, we investigated whether the inflammatory molecule osteopontin (OPN) might have a prognostic impact in a cohort of MetS patients (n=85) with baseline normal glycaemia or impaired fasting glucose (IFG) over one year of recommended pharmacological treatments and Mediterranean diet. Patients were then followed up for 12months with intermediate evaluation after 6months. At all time points, anthropometric and clinical data were recorded, alongside with haematological and biochemical profiles, including serum concentrations of OPN. As expected, Mediterranean diet improves glycaemic profile in patients with IFG. Baseline serum OPN failed to be associated with baseline anthropometric or biochemical variables. At baseline, higher levels of OPN were shown in patients with IFG as compared to normal glycaemia. Two distinct subgroups of patients in whom OPN decreased or remained stable/increased at follow-up were identified. When higher serum OPN levels were observed at baseline, greater reduction was observed at 1-year follow-up. Reduction in circulating OPN levels was associated with metabolic improvement in terms of blood pressure, LDL-c, HDL-c, and glycaemia. At both univariate and adjusted logistic regression analyses, serum OPN emerged as an independent predictor of glycaemic profile improvement at 1-year follow-up (adjOR 1.05 [1.00-1.10]; P=.041). In conclusion, pharmacological and dietetic interventions improved glycaemic profile in patients with MetS. In particular, glycaemic improvement was demonstrated in patients who also reduce circulating OPN levels. Higher OPN levels at baseline predict normalization of glycaemic profile.
