A variety of immunologic mechanisms may theoretically give rise to disease in the salivary glands. Among them are abnormal antibody production, hyper-reactive T-lymphocytes, and mono- or oligoclonal expansions of B-lymphocytes, While it is not clear which, if any, of these mechanisms are of prime importance in the immunopathology of salivary gland disease, they provide a framework, within which to discuss theoretical approaches to the treatment of autoimmune salivary gland disease. Among the techniques used to decrease antibody-induced damage are non-steroidal anti-inflammatory agents, plasmapheresis, and corticosteroids. Cyclosporin, monoclonal antibodies, and biologic response-modifiers may be used to modulate T-cell function, and anti-idiotype antibodies or immunosuppressive agents may be used to treat malignant expansions of B-cells. Although the generally benign nature of autoimmune salivary gland disease precludes the use of many of the potentially toxic treatment regimens discussed here, the appreciation of these approaches to immunomodulation provides a basis upon which to develop new and innovative therapeutic strategies.
