title: Plasma levels of brain derived-neurotrophic factor and catecholamine metabolites are increased during active phase of psychotic symptoms in CNS lupus: a case report.
abstract: In the present study, the authors reported a case of systemic lupus erythematosus (SLE) with central nervous system involvement (CNS lupus). The authors also longitudinally investigated plasma levels of brain-derived neurotrophic factor (BDNF) and catecholamine metabolites in the patient, and found that plasma levels of BDNF, 3-methoxy-4-hydroxyphenylglycol (MHPG), and homovanillic acid (HVA) were raised in accordance with the severity of psychotic symptoms in this case of CNS lupus. These results suggest that it is useful to measure plasma levels of BDNF and the catecholamine metabolites in order to predict the severity of psychotic symptoms in CNS lupus and to provide a differential diagnosis from that of steroid-induced psychosis.
