BACKGROUND: Brain-derived neurotrophic factor (BDNF) plays an important role in the regulation of synaptic plasticity and neurotransmitter release across multiple neurotransmitter systems. Recent studies have suggested that BDNF plays a role in the pathogenesis of psychiatric symptoms in patients with systemic lupus erythematosus (SLE). OBJECTIVES: We hypothesized that the polymorphism of BDNF Val66Met is associated with the emergence of psychiatric symptoms (PS) and serum BDNF levels in SLE patients. To examine the hypothesis, we compared the BDNF Val66Met polymorphism and serum BDNF levels in patients with SLE with or without PS. METHODS: Psychiatric symptoms were assessed in 54 patients with SLE. PS were evaluated using the Brief Psychiatric Rating Scale. Genotyping was carried out using a 54-nuclease assay. Serum BDNF levels were measured by using enzyme-linked immunosorbent assay. RESULTS: The presence of the Met allele was not significantly associated with the presence of PS or with serum BDNF levels in patients with SLE. CONCLUSION: Our data do not support the common variant Val66Met of the BDNF gene as an etiologic factor in the various forms of PS and serum BDNF levels in SLE.
