Abstract
Introduction
The co-occurrence of generalized anxiety disorder and personality disorders suggests the existence of association between the neurobiological predispositions leading to the development of these disorders and activation of cytokine system. Pro-inflammatory chemokines such as CCL-5/RANTES (regulated upon activation normal T cell expressed and secreted) and CXCL12/SDF-1 (stromal derived factor) play an important role in immune response.
Methods
A total of 160 participants were enrolled in the study, 120 of whom comprised the study group (people with the dual diagnosis of personality disorder and generalized anxiety disorder). The mean age was 41.4 ± 3.5 years (range: 20–44 years). The control group consisted of 40 healthy individuals in the mean age of 40.8 ± 3.1 years (range: 20–43 years). A blood sample was collected from each participant and the plasma levels of the CCL-2/MCP-1 (monocyte chemoattractant protein-1), RANTES and SDF-1 chemokines were determined by ELISA.
Results
Increased levels of MCP-1 and SDF-1 were found both in women and in men versus the control group for all types of personality disorders. The levels of CCL-5 in men were significantly increased versus the control group and significantly higher in women than in men. Neither women nor men with avoidant or obsessive-compulsive personality disorder showed any significant differences in MCP-1 or SFD-1 levels. In subjects with borderline personality disorder, the levels of the study chemokines were higher in women than in men.
Conclusions
Our study has shown the need for determination of proinflammatory interleukins which are considered as biomarkers of personality disorders and generalized anxiety disorders.
