NGF peptide and tryptase activity were shown to be significantly and persistently higher in saliva of BMS subjects, with respect to control values. Conversely the salivary levels of SP were shown to be significantly lower, while neutrophil markers didn't show any change. We conclude that the neuropathic origin of the disease is confirmed at salivary level. Furthermore, the higher tryptase activity indicates a possible involvement of mast cells. The salivary neuropeptide concentration in BMS subjects, together with mast cell derived compounds, could be useful biomarkers for diagnosis and monitoring of this disease.
