In an open-controlled trial--oral washes (20 patients) versus test (19 patients)--, we have studied the effects of AM3 (a new oral BRM) on clinical evolution of the recurrent stomatitis (RAS) syndrome. The results obtained at 6th month showed significant decreases on ulcer numbers (p less than 0.001) as well as in their mean duration time (p less than 0.001) due to the AM3 treatment. From a pathophysiologic point of view, the study of the NK peripheral blood cells (Leu 11/CD16) suggests the existence of two kinds of RAS-patients: those showing normal NK cell numbers (approximately 33%) and those ones showing a partial lack in the NK numbers (approximately 67%). These results suggest different rational new approaches to treatment, based on new pathophysiological concepts.
