Influence of various treatment methods on the content of cytokines in saliva of patients with chronic sialadenitis

Aim. Study of the main cytokines (interleukin-1β and -2, interferon γ) in the mixed saliva from patients with chronic sialadenitis on the basic and comprehensive treatment dynamically.

Methods. During the period of 2014 to 2017 we performed examination and treatment of patients with salivary gland diseases. Out of them we defined a group with chronic non-specific sialadenitis including 45 patients seen in the clinic in exacerbation. Patients in the comparison group received basic treatment. Patients in the study group additionally to conventional treatment were administered local immunotherapy. Measurement of cytokine levels in the oral fluid was performed in 45 patients with chronic sialadenitis in exacerbation and in 10 practically healthy subjects.

Results. The level of interleukin-1β in saliva was found to be significantly increased before treatment (p <0.05). After the treatment interleukin-1β level in saliva decreased in both groups but most significantly this parameter decreased in the study group. After including local immunocorrection into the treatment complex dynamic decrease of interleukin-2 to 14.7±0.4 pg/ml was registered, which apparently is associated with stabilization of immune processes in the oral cavity. After the treatment conducted according to traditional scheme in the comparison group the level of interferon γ in saliva increased to 7.2±0.2 pg/ml which is 1.1 times higher than before treatment.

Conclusion. In patients with chronic sialadenitis in exacerbation the level of interleukin-1β statistically significantly increases by 1. times (p <0.05), interleukin 2 - by 2.1 times (p <0.05) and the level of interferon γ decreases by 1.4 times (p <0.05) which is indicative of immunological signs of inflammatory reaction; use of local immunocorrection leads to more prominent decrease of interleukin-1β (by 20.3 vs 16.2% in comparison group; p <0.05), interleukin-2 (by 38.8 vs 26.6%; p <0.05) and increase of interferon γ (by 21.2 vs 12.5% in comparison group; p <0.05).
