Comparison of pre-and post-operative stress levels in patients with allergic rhinitis and non-allergic rhinitis

摘要

The effects of stressful events, such as surgery, on patients with allergic diseases are unclear. The aim of this study was to evaluate whether patients with allergic rhinitis (AR) are more susceptible to stress and oxidative stress than non-allergic individuals. 20 AR patients and 20 non-allergic rhinitis (NAR) patients were recruited to this study and underwent nasal septoplasty. To evaluate the degrees of stress and oxidative stress, we collected urine and blood samples 1 day before and 1 day after surgery. Stress was assessed by measuring urine cortisol levels. Oxidative stress was assessed by calculating the balance of reactive oxygen metabolites (ROM) measured by the diacron reactive oxygen metabolites test, and antioxidant capacity (AC) was measured by the biological antioxidant potential test. In both groups, the level of post-operative urine cortisol was significantly higher than the pre-operative level, with no significant difference between the two groups. ROM levels were significantly higher in both groups after surgery than before surgery. The antioxidant capacity of the AR group was lower after surgery than before surgery, while it was greater in the NAR group after surgery. There were no significant differences in pre- or post-operative ROM or AC levels between the two groups. The ROM/AC ratio was significantly higher after surgery in the AR group than it was in the NAR group. The postoperative ROM/AC imbalance of AR patients suggests that these patients might be vulnerable to stress, especially oxidative stress.
