| Outline of Final Research Achievements |
Fifty-eight remitted patients in major depressive disorder (MDD) were followed up at least one year. We measured serum levels of brain-derived neurotrophic factor (BDNF), proBDNF, and interleukin-6(IL6), which are considered to be biological markers for MDD. (1)Twenty-four of 58 MDD patients were relapsed within 6 months after remission. (2)No differences were found in serum levels of BDNF proBDNF, and IL6 at baseline in the relapsed group and the non-relapsed group. (2)Serum BDNF levels were significantly lower in the relapsed group than in non-relapsed group at 3 months after remission. (3)Serum IL6 levels were significantly higher in the relapsed group than in the non-relapsed group at 3 months after remission. (4)No diference was found in serum proBDNF levels between the relapsed group and the non-relapsed group. The findings suggest that serum levels of BDNF, and IL6 might be predictable biomarkers for relapse in MDD.
