The aim of this study was to compare neuropeptide levels between patients with major psychiatric disorders and healthy controls, and examine their association with symptoms and cognitive function. The results showed that plasma neuropeptide levels were not significantly different between patients and healthy controls, and were not significantly correlated with symptoms or cognitive function.
Aim: We aimed to compare neuropeptide levels between patients with major psychiatric disorders and healthy controls and examine their association with symptoms and cognitive function. Methods: The participants were 149 patients with schizophrenia, 115 patients with bipolar disorder (BD), 186 unremitted patients with major depressive disorder (MDD), and 350 healthy controls. Psychiatric (schizophrenic, manic, and depressive) symptoms, sleep state, and cognitive (premorbid intelligence quotient, general cognitive, and memory) functions were evaluated. A multiplex immunoassay kit was used to measure cerebrospinal fluid (CSF) and plasma alpha-melanocyte-stimulating hormone (MSH), beta-endorphin, neurotensin, oxytocin, and substance P levels. Results: The verification assay revealed that CSF alpha-MSH, beta-endorphin, neurotensin, oxytocin, and substance P levels were too low to be reliably measured, while plasma alpha-MSH, beta-endorphin, neurotensin, oxytocin, and substance P levels could be successfully measured. Plasma alpha-MSH, beta-endorphin, neurotensin, oxytocin, and substance P levels were not significantly different between patients with schizophrenia, BD, or MDD and healthy controls. Plasma alpha-MSH, beta-endorphin, neurotensin, oxytocin, and substance P levels were not significantly correlated with psychiatric symptom scores in patients with schizophrenia, BD, or MDD and cognitive function scores in patients or healthy controls. Conclusion: Our data suggest that plasma neuropeptide levels do not elucidate the involvement of neuropeptides in the pathology of schizophrenia, BD, or MDD.
