[Acne conglobata: personality and psychological sequelae in 13-cis-retinoic acid therapy. Initial results].

16 patients suffering from acne conglobata were prospectively examined by means of analytical interviews and 5 psychometric procedures before and 6 months after oral treatment with 13-cis retinoic acid (isotretinoin). In comparison with a control group of psychosomatic patients, acne conglobata patients are more frequently affected by childhood influences leading to a neurotic personality structure already before the outbreak of acne; the patients more often complain of disturbed social contact, depressive moods, or general disorders. After successful treatment with isotretinoin, we observed augmented self-confidence and positive aggressiveness, on one hand, and increase of anxiety depressive moods, and general complaints, on the other. These effects are not drug related in a pharmacological way. These observations suggest the influence of psychic factors in the pathogenesis of acne conglobata. Regarding the medical management of these patients, it should be considered that psychic and psychosomatic disorders might be intensified after successful drug therapy.
