The nesfatin 1 level in male patients with manic episode and alterations of nesfatin 1 level after antipsychotic and electroconvulsive treatment

BackgroundNesfatin 1 is a newly identified peptide structured satiety hormone that is claimed to be responsible for the provision of appetite and metabolic regulation in hypothalamus. The change in appetite and energy is a well-known clinical feature of affective disorders and within treatment. We aimed to investigate serum nesfatin 1 level in patients with bipolar disorder who were in manic episode and the influences of treatment modalities on nesfatin 1 level.MethodsSixty eight patients were elected and were divided into two groups as: antipsychotic treatment (haloperidol 10-30 mg/daily+quetiapine 100-900 mg/daily) arm and ECT+antipsychotic treatment arm. And 30 healthy controls were included in the study.ResultsThere was no significant difference according to mean age between patients and controls. Initial nesfatin 1 levels in patients and in both subgroups of patients were statistically lower than in healthy control group. The initial level of nesfatin 1 between ECT+antipsychotic and pure antipsychotic patient groups was not statistically significant. We found a trend of increment in nesfatin 1 level after treatment in both patient groups.ConclusionsThis study is the first that revealed significantly lower nesfatin 1 level in manic episode than healthy controls. ECT+antipsychotic and antipsychotic treatments have no significant effects on nesfatin 1 level after manic episode treatment. These findings should be interpreted cautiously because of small sample size and being drug free only for one week.
