Circulating leptin levels in elderly subjects with and without cerebrovasular disease.

Serum concentrations of leptin was investigated in 40 patients with ischemic stroke, in context of the size of the lesion and also in 40 non-diseased controls, matched according to age, gender and waist hip ratio. Serum leptin concentrations were determined in ng/ml with ELISA and computer tomography (CT) scan was performed in patients to estimate lesion size in cms. Serum leptin concentrations were found to be significantly higher (p < 0.001) in stroke patients (51.61+1.39), compared with controls (37.76+1.207). Moreover, positive correlation (r=0.93) existed between serum leptin level and infarction size in patients with stroke.
