    Abstract:
    Human immunodeficiency virus (HIV) associated salivary gland disease is defined as the presence of enlargement of one or more major salivary glands and/or diminished salivary function in an HIV infected individual. It has a number of similarities to, as well as differences from, Sjögren's syndrome (SS). We studied the sialochemistry of stimulated parotid saliva of 11 patients with HIV associated salivary gland disease and bilateral parotid gland enlargement, and compared these findings with those of 15 HIV negative controls, 13 HIV positive individuals with no salivary gland involvement and 18 individuals with SS. The patients with HIV associated salivary gland disease had a significant decrease in the level of salivary protein, with increases in salivary IgA, lysozyme and albumin compared to the HIV negative controls. There were no changes in concentration of electrolytes. The sialochemistry among the patients with HIV associated salivary gland disease was unrelated to the degree of immune suppression and did not change over a 6 month period. The observed changes were similar to those of SS but less pronounced. The similar clinical, histologic and sialochemical features of HIV associated salivary gland disease and SS suggest that these conditions share common pathogenetic mechanisms, which may be modified in the former by the HIV infection.
