[Immunology and psychiatry].

This review of scientific literature comes within the interest arisen from ten years by psychoneuroimmunology, a field connecting several disciplines and illustrating in a new way the psychosomatic relationships. A first category of works has been dedicated to the study of psychiatric disorders associated with various diseases concerning immunity (systemic diseases, endocrine diseases, cancers, infectious diseases), but also to the possible effect of distressing life events on the upset activation of immune functions, or even to the discovery of predisposing personality profiles (type C profile, depressive vulnerability). A second category of works concerns the analysis of the immune disturbances associated with certain psychiatric diseases, such as depression or schizophrenia, but also with some distressing life conditions, like bereavement. Animal experimentation and human experimentation provide various informations on the factors conditioning the immunomodulating effects of stress, sometimes in the direction of an inhibition, sometimes in the direction of an activation of immune functions. Finally, several papers shed light on the immunomodulating effects of psychotropic drugs. All these works open new horizons to the scientific knowledge and let us glimpse an extension to the use of psychologic therapeutics, as well of pharmacological ones as of non pharmacological.
