Treatment cell-mediated immunomodulation

Tenenbein 1992). More important from the perspective of immunomodulation is the abuse of so-called room odorizers or volatile nitrites. These compounds—such as amyl nitrite, butyl nitrite, and isobutyl nitrite (IBN)—produce vasodi-lation of the cerebral vessels, resulting in euphoria (Haverkos and Dougherty 1988) and a reported enhancement in sexual function. Initially used clinically in the treatment of angina pectoris, their use appears to be prevalent in the homosexual community and may be associated with Kaposi s sarcoma (Newell et al. 1984). Use of these compounds has been demonstrated to result in decreased immune function, particularly T-cell-mediated immunity (Dax et al. 1991 Lotzova et al. 1984 Soderberg and Barnett 1991 Ratajczak et al. 1995). The association between inhalants and Kaposi s sarcoma is currently the subject of increased research interest.
