Abstract EN
Purpose.
Patients with ulcerative colitis (UC) frequently present with psychological disturbances as well as dysfunctions of autonomic nervous system (ANS).
Salivary alpha-amylase (sAA) secretion is predominantly controlled by sympathetic nervous activity, while salivary fluid secretion is by parasympathetic nervous activity.
Thus, it is speculated that alterations of salivary secretion may be addressed in UC populations.
Methods.
Thirty-five UC patients as well as 32 age- and sex-matched healthy controls were enrolled.
Saliva samples before and after citric acid stimulation were collected from each participant, and salivary flow rate (SFR) was calculated accordingly.
Western blotting and quantitative PCR were applied to measure the sAA level and sAA gene (AMY1) copy number, respectively.
The psychological disorders, anxiety and depression, were evaluated by the scoring system of Hospital Anxiety and Depression Scale (HADS) for each participant.
Results.
We observed robustly increased prevalence of anxiety (p<0.001) as well as depression (p<0.001) in UC patients relative to controls.
Interestingly, we detected elevated basal (p=0.015) and stimulated (p=0.021) sAA levels in the UC populations compared to controls.
However, no differences were found for basal (p=0.643) or stimulated (p=0.402) SFR between the two study groups.
Besides, AMY1 gene copy number was comparable between UC patients and controls.
Conclusions.
Our results reveal an overactivity of the sympathetic nervous system and a normal activity of the parasympathetic nervous system in the UC population.
