Aim. The aim of this study was to investigate the dose-dependent effects of prednisolone administration on serum vaspin levels and correlate this with changes in the BMI and lipogenesis in rats. Materials and Methods. Twenty-four albino Wistar male rats weighing between 190–240 g were divided into four groups, three experimental (5 mg/kg, 10 mg/kg, and 20 mg/kg prednisolone) and one control. The prednisolone groups were given once-daily doses for 30 days, orally. In addition, the rats were weighed, and their height and waist circumferences were measured once a week. At the end of 30 days, vaspin and glucose levels were measured from blood samples. Results. In the prednisolone groups, the vaspin levels significantly increased when compared with the control group. The control group has a serum vaspin level of 155 ± 20.99 pg/mL and this level has been increased by prednisolone administration in a dose dependent manner. In the prednisolone groups, especially the 10 mg/kg and 20 mg/ kg groups, the glucose levels increased in a dose dependent fashion. Conclusion. Prednisolone administration significantly increased serum glucose and vaspin levels in a dose dependent manner, indicating that the increase in the serum vaspin levels could be related to the increase in the serum glucose concentration. Vaspin can be a molecule that is released in response to increased glucose and can be a rebound defense mechanism to modulate the blood glucose concentration. We suggest vaspin as a potential target for the treatment and diagnosis of diabetes mellitus and other metabolic disorders.
