摘要：Role of various cytokines have been implicated in the development and perpetuation of Sjögren's syndrome (SS), but no specific cytokine could be determined as a major contributor to the SS. Salivary and serum interleukin 6 (IL-6) levels have been studied previously in patients with SS, but data upon salivary and serum basic fibroblast growth factor (bFGF) in SS are lacking. The aim of this study was to evaluate levels of salivary and serum IL-6 and bFGF in 18 patients with SS, age range 32–79, mean 54.05 years. Control group consisted of 23 healthy participants, mean age 25 years. Serum IL-6 and bFGF levels were not significantly different between patients with SS and healthy controls. Elevated levels of salivary IL-6 and bFGF in patients with SS when compared to the healthy controls were found (p IL-6 and bFGF in patients with SS might originate from local production probably having source in the salivary glands.
