title: Antiphospholipid, antinuclear, Epstein-Barr and cytomegalovirus antibodies, and soluble interleukin-2 receptors in depressive patients.
abstract: To determine whether depression might be associated with serologic indices of autoimmune processes or active virus infections, we measured the following parameters in healthy controls, minor, simple major and melancholic patients: antiphospholipid (anticardiolipin, antiphosphatidylserine), antinuclear, and Epstein-Barr (EBV) and cytomegalovirus (CMV) antibodies. In addition, the soluble interleukin-2 receptor (sIL-2R) circulating levels in serum were measured and used as a marker of T cell activation. The anticardiolipin antibody titers were higher in melancholics than in healthy controls and minor depressives. Antinuclear antibodies were present significantly more frequently in depressed patients than in normal volunteers. The anticardiolipin and antinuclear antibody titers were significantly and positively intercorrelated. Depression is characterized by increased serum circulating levels of sIL-2Rs compared to the healthy state. Antinuclear-positive subjects exhibited significantly higher sIL-2Rs than those without detectable antinuclear titers. There was a positive correlation between anticardiolipin activity and sIL-2Rs. We found no evidence that depression is linked to EBV or CMV infection.
