Abstract
Background The prevalence of allergic diseases is gradually increasing worldwide. The most common such allergic disease is allergic rhinitis (AR). Objective The present study investigated the possible relationship between seasonal AR and the thiol-disulfide balance and zinc and copper levels in adult individuals. Study Design and Methods 130 male and female adults were included in the study. The participants' serum thiol-disulfide balance and zinc and copper levels were measured spectrophotometrically using commercial kits. Statistical significance was accepted as p < 0.05 between the groups. Results The serum copper (p = 0.001), native thiol (p = 0.006), reduced thiol (p < 0.001), and thiol oxidation reduction ratio (p < 0.001) levels were significantly lower in the seasonal AR group than in the control group. Conclusion In AR patients, the low level of copper, which is an important trace element, the deterioration of the thiol-disulfide balance, which represents a unique indicator of the oxidant-antioxidant balance, the increased disulfide level caused by oxidative stress, and the decreased native thiol level can all serve as important biochemical markers.

Abstract
To date, no disease-specific tool has been available to assess the impact of chronic rhinosinusitis with nasal polyps (CRSwNP) on health-related quality of life (HRQoL). Therefore, the purpose of this study was to develop and validate a questionnaire specifically designed to this aim: the Nasal Polyposis Quality of Life (NPQ) questionnaire. As indicated in the current guidelines, the development and validation of the NPQ occurred in two separate steps involving different groups of patients. The questionnaire was validated by assessing internal structure, consistency, and validity. Responsiveness and sensitivity to changes were also evaluated. In the development process of NPQ an initial list of 40 items was given to 60 patients with CRSwNP; the 27 most significant items were selected and converted into questions. The validation procedure involved 107 patients (mean age 52.9 ± 12.4). NPQ revealed a five-dimensional structure and high levels of internal consistency (Cronbach’s alpha 0.95). Convergent validity (Spearman’ coefficient r = 0.75; p < 0.01), discriminant validity (sensitivity to VAS score), and reliability in a sample of patients with a stable health status (Interclass Coefficient 0.882) were satisfactory. Responsiveness to clinical changes was accomplished. The minimal important difference was 7. NPQ is the first questionnaire for the assessment of HRQoL in CRSwNP. Our results demonstrate that the new tool is valid, reliable, and sensitive to individual changes.
