P01-109 - Clinical-dynamic Characteristics of Depressive Disorders Comorbid with Anxiety Disorders

Abstract

The aim of this study was to find clinical-dynamic characteristics of depressions comorbid with anxiety disorders.

Methods

140 patients have been observed: basic group - 70 patients with depressive disorder with anxiety disorder; control group - 70 patients with depressive disorder alone. All patients were treated with SSRIs. We used in study 17-item HRS-D and CGI.

Results of investigation

Baseline average score according to CGI has constituted 4,8±0,6 and 4,5±0,7. Comparative assessment of clinical picture of depression in groups has shown that in basic group more frequently (p< 0,05) dysphoric (31,4% and 12,9%) and conversion (21,4% and 11,4%) syndromes were noticed, while in the control group - adynamic (30% and 12,9%,). Statistical analysis of data of age at the onset of depressive disorder has revealed intergroup differences (p< 0,05), testifying to emerging depressive disorders in patients of basic group at younger age (39,6±12,1 years), as compared with patients of control group (43,9±12,9 years).

Index of cyclicity of disease in patients with RDD was calculated as ratio of disease duration in years to cycles of disease. Average value of the corresponding index in basic and control groups differed reliably (p< 0,05) and has constituted 3,2±1,1 and 7,6±1,6. I.e., in the basic group exacerbation of depressive symptoms in recurrent depressive disorder was noticed more frequently as compared with control group.

Thus, comorbidity of depressive and anxiety disorders results in complicating symptoms, change of its syndromal validation, more adverse course (acceleration of depressive phases in recurrent depressive disorder).
