[Examination of the hereditary burden for the depressive disorder].
BACKGROUND
Depressive disorders represent a group of diseases of a very complex etiology. The onset of this disease is determined by genetic and psychosocial factors. The presence of psychiatric disorders in families affects the onset and severity of the depressive disorder in offspring. The aim of this study was to determine the existence of differences in socio-biographic and clinical parameters between a group of depressive patients who have first degree relatives with psychiatric disorders (G1) and a group of depressive patients who have no first degree relatives with psychiatric disorders (G2).


METHODS
A number of 57 hospitalized patients were included and divided in two groups. Parameters observed: socio-demographic and biographic data, severity of the clinical status, period of the disease. Data were collected by using a socio-demographic questionnaire, Clinical Global Impression-Severity Scale and Hamilton depressive disorder scale.


RESULTS
It has been found that the patients from G1 have a significantly higher rate for the parameter "broken home", p=0.014. Also, there were significant differences for the parameters: early insomnia (p=0.026), genital symptoms (p=0.016), (more manifested in G1). The results of the multivariate regression analysis showed that patients from G1 having higher level of hereditary burden had a more severe clinical status on the day of the admission to hospital.


CONCLUSIONS
The research showed the influence of aggregation of psychiatric disorders in families on the onset and severity of depressive disorders. The interaction of genetic and psychosocial factors has been confirmed in the etiology of depression.
