Introduction and objectives: Pollen calendars have been proved clinically important in allergic disease management, as differences in airborne allergens exist not only between different countries but also between regions of the same country as well. This study aims to provide new data regarding the atmospheric pollen and fungi content of a Mediterranean region (Western Thrace/North-East Greece) and discuss seasonal trends, differences in pollen grains and fungi spores’ circulation over the years, and correlations with climate parameters. Material and methods: A 7-day continuously running volumetric trap was used to collect circulating pollen grains and fungi spores. Pollen taxa and fungi were characterized by standard protocols and counted as grains /m3 and average total grains and spores. The primary allergenic pollen season was discovered, and their 10-day averages were measured over time. Correlations with temperature, rain, and humidity were assessed by single linear regression analysis. Results: Pollen grains from nine pollen families were identified, including five arboreal, two nonarboreal taxa, and spores from two fungi species. The three most prevalent taxa were Oleaceae, Poaceae, Pinaceae, and Cladosporium in the fungi. Peak pollen concentrations were detected during April and May, with daily averages exceeding 170 grains/m3. Poaceae presented the longest pollen season of 342 days and Oleaceae the shortest, extending to only 110 days, during the 3years. Cladosporium was the fungus with the highest spore concentration (180,129.9 spores) compared with Alternaria (28,026.1 spores). Correlations with meteorological parameters showed variable associations among different taxa, with rainfall and relative humidity being the most significant determinants. Conclusion: In this study, the pollenic and fungal spectrum of a Mediterranean region and information that can be proved clinically significant for the appropriate diagnostic and therapeutic approach of allergic patients was presented.

Introduction: The relationship between disease severity and exposure to allergens in allergic rhinitis (AR) patients is not fully clarified presently. We aimed to detect the correlation between airborne pollen and fungi concentrations in a Mediterranean region with symptom scores.Methods: A total of 98 patients suffering from AR rated their symptoms at the time of exacerbation using the Total 5 Symptoms Score (T5SS) and the Visual Analogue Scale (VAS). Patients' quality of life (QoL) was estimated by using either disease-specific (Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and mini-RQLQ) or generic (Short-Form 36 (SF-36) and Beck Depression Inventory (BDI)) questionnaires. All patients' responses were correlated with aerobiological data. Skin prick tests (SPTs) were used to detect sensitivities to the most common registered pollen and fungi species.Results: A significant positive correlation between total pollen and fungi counts and disease-specific questionnaires was found only for the RQLQ. Accordingly, a significant positive correlation was found between total pollen and fungi counts and T5SS (r = 0.655, p = 0.021), with breathing (r = 0.620, p = 0.032) and sneezing (r = 0.660, p = 0.020) being strongly affected. Moreover, a tendency toward a higher VAS score was found as total pollen and fungi counts increased (r = 0.523, p = 0.081). Conclusion:We found a significant correlation between patients' symptoms and pollen and fungal air concentrations. Our results emphasize the clinical significance of pollen and fungi maps in everyday clinical practice.

Objective This study aimed to develop the Greek versions of the Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire for adult and pediatric populations, discuss their differences and detect the impact of age and gender on quality of life questionnaire results. Method Ninety-eight patients with allergic rhinitis participated. Quality of Life evaluation was made by two generic (Short Form-36 and Beck Depression Inventory) and two disease-specific questionnaires (Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire). Symptom evaluation was made by the Total 5 Symptoms Score assessment. Results Internal consistency and test–retest reliability of both questionnaires was high. Convergent validity showed statistically significant negative correlations of total Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire with overall Short Form-36 Health Survey score and positive correlations with Beck Depression Inventory and Total 5 Symptoms Score. Discriminative validity demonstrated statistically significant improvement for all instruments and all domains after treatment. Females presented highly significant increased scores. Patient age was positively correlated with total scores of Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire. The clinically significant improvement after treatment was higher among females than males, while it was independent of patient age. Conclusion Rhinoconjunctivitis Quality of Life Questionnaire and Mini-Rhinoconjunctivitis Quality of Life Questionnaire proved to be valid and reliable methods of assessment of allergic rhinitis-related quality of life in children, adolescents and adults.
