• Adiponectin
• Diabetes
• IL-1 beta
• Leptin
• Mild cognitive impairment

The aim of the study was to determine the serum levels of adiponectin, leptin and IL-1 beta in elderly diabetic patients with and without mild cognitive impairment (MCI) and to examine the associations of these markers with clinical and cognitive parameters. A biochemical evaluation was performed of 62 seniors with type 2 diabetes (T2DM) and MCI, and 132 seniors with T2DM but without MCI (controls). Serum leptin and IL-1 beta levels were higher and adiponectin concentration was lower in MCI patients than controls. In MCI subjects, adiponectin level was negatively correlated with leptin, IL-1 beta levels and BMI. Leptin concentration was correlated with IL-1 beta level. Univariate logistic regression models revealed that the factors which increased the likelihood of diagnosis of MCI in elderly patients with T2DM were higher levels of HbA1c, leptin, IL-1 beta and triglycerides, as well as lower levels of adiponectin and HDL cholesterol. Similarly, previous CVD, hypertension, hyperlipidemia, retinopathy, nephropathy, hypoglycemia, longer duration of diabetes, increased number of co-morbidities, older age, fewer years of formal education were found to be associated with MCI. The multivariable model indicated fewer years of formal education, previous CVD, hypertension, increased number of co-morbidities, higher HbA1c and IL-1 beta levels and lower adiponectin level. Elderly diabetic patients with MCI have higher levels of leptin and IL-1 beta and lower levels of adiponectin. Further prospective studies are needed to determine the role of these markers in the progression to dementia.
