In the present study, we compared plasma levels of interleukin-6 (IL-6), tumor necrosis factor-alpha(TNFalpha), and brain-derived neurotrophic factor (BDNF) among selective serotonin reuptake inhibitor (SSRI)- or serotonin noradrenaline reuptake inhibitor (SNRI)-responsive depressed patients (n=31), SSRI- or SNRI-refractory depressed patients (n=20), and(More)
Electroconvulsive therapy (ECT) is effective for patients with antidepressant medication-resistant depression. However, the mechanisms of ECT's effectiveness for treating depression are not fully understood. We therefore investigated ECT's effects on blood levels of brain-derived neurotrophic factor (BDNF), catecholamine metabolites, and nitric oxide (NO)(More)
Brain-derived neurotrophic factor (BDNF) is an important member of the neurotrophin family of growth factors, abundant in the brain and periphery. Researchers have reported that serum BDNF levels in drug-free depressed patients are lower than those of healthy controls, and have proposed that these low levels might reflect a failure of neuronal plasticity in(More)
BACKGROUND We investigated the association between serum proBDNF, a precursor of brain-derived neurotrophic factor (BDNF), and response to fluvoxamine in patients with major depressive disorder (MDD) using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR): physically healthy and free of current alcohol or(More)
Depression is a risk factor for coronary heart disease (CHD). It has been demonstrated that there is a potential role of nitric oxide (NO) in the relationship between depression and CHD risk as well as an effect of antidepressants on NO production. This study included 40 in- or outpatients in our university hospital who met the DSM-IV-TR criteria for major(More)
OBJECTIVE We investigated the plasma levels of interleukin (IL)-6 and 5-HTT polymorphisms in patients with major depressive disorder (MDD). This is the first report, to our knowledge, of an investigation into the association between 5-HTT gene polymorphism, plasma IL-6 levels, and responses to selective serotonin reuptake inhibitors (SSRIs) in Japanese(More)
In the present study, we examined the effects of olanzapine on plasma levels of catecholamine metabolites, brain-derived neurotrophic factor, and cytokines (interleukin-2, interleukin-6 and tumor necrosis factor-alpha) using 32 olanzapine-treated schizophrenic patients and age and sex-matched 55 healthy individuals. Treatment with olanzapine for 8 weeks(More)
There is growing evidence that blood levels of brain-derived neurotrophic factor (BDNF) and 3-methoxy-4-hydroxyphenylglycol (MHPG), a major metabolite of noradrenaline, are related to depression-associated personality traits as well as to depressive, suicidal and anxious states. Psychological job stress is well known to lead to symptoms of depression,(More)
A combination treatment with a mood stabilizer and an antipsychotic drug is often used in as many as 90% of subjects with acute mania. Recently, augmentation therapy with atypical antipsychotics has been investigated in both the acute and long-term treatment of bipolar disorder with or without psychosis. In the present study, the authors investigated the(More)
OBJECT We investigated an association between the polymorphism of brain-derived neurotrophic factor (BDNF) gene Val66Met and the response to mirtazapine in Japanese patients with major depressive disorder (MDD). We also examined mirtazapine's effects on the serum BDNF and plasma levels of catecholamine metabolites in these patients. METHODS Eighty-four(More)
