Psychological stress evaluation of patients with bronchial asthma based on the chromogranin a level in saliva.

摘要

To evaluate the involvement of stress in asthmatics we measured the concentration of chromogranin A (CgA) in saliva as an indicator of psychological stress and investigated its correlation with peak expiratory flow (PEF), a visual analog scale (VAS) score of symptoms, and the score of the Short-form 36 health survey questionnaire (SF-36) in 62 adult asthmatics. CgA had a significant correlation with role physical (RP) (r = -0.298, p < 0.05), role emotional (RE) (r = -0.294, p < 0.05) and the physical component summary (PCS) (r = -0.310, p < 0.05) of SF-36, and VAS score (r = -0.435, p < 0.01). We concluded that the concentration of CgA reflects the stress in asthmatics caused by work or daily life limitations.
