Dynamics of local cytokine status in patients with parotid salivary gland sialadenosis depending on the treatment algorithm

Sialadenosis is a dystrophic disease of the salivary glands parenchyma, which leads to secretory disorders and hypertrophy of salivary glands. Sialadenitis develops in cases of secondary inflammation. Standard methods and medications for the treatment of sialadenosis lead to regression of clinical manifestations and remission. Usage of herbal extracts with prolonged action has a long-term local anti-inflammatory effect with minimal side effects, including those affecting oral mucosa. However, their use in the complex treatment of sialadenosis has been scarcely studied. Objective of our investigation was to estimate cytokine status dynamics in saliva from the parotid glands in the patients with sialadenosis and hypothyroidism during complex treatment which included the prolonged-action herbal remedy. 52 patients with sialadenosis of parotid salivary glands and hypothyroidism were divided into 2 groups: in the I group, 26 patients received basic therapy; in the II group, 26 patients received basic therapy + herbal drugs with prolonged effect as resorbable tablets. Control group consisted of 20 conditionally healthy people without disorders of parotid glands and thyroid gland. Comparative evaluation was performed 1 and 6 months after starting the treatment, with respect to clinical findings, sialometry and cytokine profile. The content of interleukins IL-1β, IL-6, IL-10 and tumor necrosis factor (TNF) was determined in saliva of parotid glands by ELISA technique. The 1st group of patients showed exacerbations within six months of basic treatment, and the sialometry data pointed to maintenance of decreased parotid function. In the 2nd group, when using basic treatment + herbal drugs, no clinical features of sialadenosis were evident within 6 months. The sialometry values were normalized, and the secretory function of the parotid glands was found to be increased. Therefore, it exerted an effect upon moisturization of oral mucosal and improvement quality of life in the patients. Regression of IL- 1β, IL-6 and TNF contents, and IL-10 increase in parotid gland secretions was significantly more pronounced at the terms of 1 and 6 months in cases treated with herbal drugs, compared to Group 1, where a conventional protocol was used. Addition of herbal drugs of prolonged action to the standard protocol of sialadenosis treatment is reasonable and effective
