Abstract

OBJECTIVE
Ghrelin and leptin, appetite-regulating hormones, play a role in mood regulation. Current data about the relation between leptin/ghrelin and depression are still controversial. This study aimed to investigate serum leptin and ghrelin levels in patients with depression and the effects of treatment on these levels.
METHODS
Serum ghrelin and leptin levels were measured before and after treatment with antidepressant drugs and/or electroconvulsive therapy in 28 patients with depression and once in 21 healthy controls.
RESULTS
Serum ghrelin levels of the patients were high in the pre-treatment. After the treatment, ghrelin levels were not different from those of the controls. We found no difference in serum levels of leptin between the patients and controls and no change with treatment. body mass index of the patients increased after the treatment especially in the drug-treated group.
CONCLUSION
The present study found increased serum ghrelin levels in depressive patients and normalization with improving of depression but no alteration in leptin levels.
