[Recurrent infections of the urogenital tract: preliminary results of a study on the clinical and immunological effects of thymopentin treatment].

We are carrying on a trial with subcutaneous injections of thymopentin in a group of patients that presented more than 2 infectious episodes of uro-genital tract in the latest 18 months. Microbiological investigations were performed with microscopic and cultural examinations before and after six weeks of treatment with thymopentin (TP5) associated with antibiotic therapy chosen on the basis of cultural response. The follow-up was prolonged to 6 months. The immunological studies were performed at the same moments, by a panel of monoclonal antibodies and by the evaluation of the NK activity and granulocytic phagocytosis. The cellular immunity was studied by skin tests. In our patients, during the follow-up period, we observed a significant reduction of infectious episodes, an increase of NK activity, and a restoration of cellular immunity in hypoergic subjects.
