Autoimmune sialadenitis

Using the European-American classification criteria the diagnosis of autoimmune sialadenitis in Sjogren's syndrome can generally be easily established or excluded. In addition, sonography performed by the ENT physician is helpful in diagnosing and especially in follow-up screening for MALT lymphomas, which 5%-10% of patients develop. Therapy of sicca symptoms is primarily symptomatic using substitution with fluids and stimulation with oral cholinergic drugs. Corticosteroids and/or antibiotics may play a role in patients with severe inflammatory episodes of autoimmune sialadenitis. Systemic therapy with immunomodulatory drugs such as azathioprine or cyclophosphamide is reserved for patients with extraglandular manifestations. However, the efficacy of this therapy is not proven by clinical studies. Rituximab, a new monoclonal CD20 antibody, seems to offer the first possibility of a causal therapy, under which the lymphoepithelial lesions in the salivary glands can disappear and saliva production improves. However, larger clinical studies are needed to evaluate the efficacy of this new therapy. Optimal treatment of autoimmune sialadenitis requires interdisciplinary collaboration between ENT physician, oral and maxillofacial surgeon, rheumatologist, ophthalmologist, dentist, and pathologist
