Concentration of the Eosinophil Cationic Protein (ECP) measured in different body fluids has been demonstrated to be a good marker of eosinophilic inflammation. In allergic asthma, ECP levels in both broncho-alveolar-lavage (BAL) fluid and serum can be used to monitor disease activity. In allergic rhinitis, the value of ECP determinations in serum and nasal secretions was not directly compared, so far. In the present study, ECP levels in blood serum (Se) and nasal secretions (NS) of grass pollen allergic and healthy individuals under pollen exposure were analyzed. Forty-three grass-pollen allergic subjects and 19 healthy volunteers were included. Grass-pollen counts were measured using Burkhard traps and a symptom scoring performed. In the allergic subjects, the mean ECP concentration in nasal secretions was 789 ± 515 ng/mL compared with 12.1 ± 7.4 ng/mL in serum; in the healthy volunteers it was 29.6 ± 15.4 ng/mL in NS compared to 9.4 ± 6.9 ng/mL in Se. ECP concentration in NS was significantly higher in allergic than in healthy subjects (P < 0.001) and in both significantly higher than in Se (P < 0.01). ECP concentration in Se did not differ significantly in patients and healthy volunteers (P > 0.05). In the allergic subjects, ECP concentration in NS but not in Se was closely correlated to symptom score and pollen exposure. We conclude that ECP levels in NS are a better marker of eosinophilic inflammation in allergic rhinitis than ECP serum levels.

Background. We aimed to apply theZHENGidentification to provide an easy and useful tool to stratify the patients with allergic rhinitis (AR) through exploring the correlation between the quantified scores of AR symptoms and the TCMZHENGs.Methods. A total of 114 AR patients were enrolled in this observational study. All participants received the examinations of anterior rhinoscopy and acoustic rhinometry. Their blood samples were collected for measurement of total serum immunoglobulin E (IgE), blood eosinophil count (Eos), and serum eosinophil cationic protein (ECP). They also received two questionnaire to assess the severity scores of AR symptoms and quantified TCMZHENGscores. Multiple linear regression analysis was used to determine explanatory factors for the score of AR manifestations.Results. IgE and ECP level, duration of AR, the 2 derived TCMZHENGscores of “Yin-Xu − Yang-Xu”, and “Qi-Xu+Blood-Xu” were 5 explanatory variables to predict the severity scores of AR symptoms. The patients who had higher scores of “Yin-Xu − Yang-Xu” or “Qi-Xu+Blood-Xu” tended to manifest as “sneezer and runner” or “blockers,” respectively.Conclusions.The TCMZHENGscores correlated with the severity scores of AR symptoms and provided an easy and useful tool to stratify the AR patients.

Aim. The aim of the study was to differentiate the endotypes in allergic rhinitis by key allergy markers in a mixed group of patients.Material and Methods. The study comprised a total of 48 patients, men and women, aged 18-60 years suffering from three endotypes of allergic rhinitis including the classic, local, and dual allergic rhinitis. The standard diagnostics of allergic rhinitis included taking a history of allergies, family history of allergic disease, video rhinoscopy, serum total IgE level assessment, allergy skin tests to house dust mite and pollen allergens, and study of eosinophilic inflammation parameters (eosinophil cationic protein, interleukin-5 (IL5), and eosinophil counts in blood and nasal secretion).Results. Based on total IgE level, the general group of patients was divided to two subgroups: subgroup 1 comprised patients with high IgE level (n = 22); subgroup 2 comprised patients with low IgE level (n = 26). Most of patients in these groups had contradictory results of allergy skin tests i.e. positive allergy skin test results in case of high IgE level (group 1) and vice versa. Cluster analysis-based exminations of general group allowed to categorize three subgroups of patients: patients with classic allergic rhinitis (n = 22), local allergic rhinitis (n = 22), and dual allergic rhinitis (n = 4). Besides, an increased rate of anxiety disorder was found in patients with local allergic rhinitis (p < 0.001).Conclusion. The obtained data showed promise for a new research trend in studying allergic rhinitis endotypes, namely: investigation of neuroimmune relationships in allergic tolerance disruption in the presence of this pathology.

Abstract Background The aim was to determine the level of inflammatory cytokines, eosinophil cationic protein and IgE in allergic rhinitis (AR) patients. Subjects and methods Blood samples were taken from 88 AR patients and 88 healthy controls (HC). Each sample was analysed for eosinophil counts by flow cytometry, IgE by ECLIA, ECP, IL-17, and IL-33 by using ELISA test. Results There was no significant difference between AR patients and the control group in age and gender. Levels of eosinophils, IgE, ECP, IL-17, IL-33 and the total symptom scores were significantly higher in AR patients than the HC (P = 0.0001). Serum ECP correlated with IL-17 (P = 0.041, r = 0.42), IL-33 (P = 0.0001, r = 080), and IgE levels (P = 0.017, r = 0.45) in the R patients. There was no correlation between IL-17 and IL-33. There was a correlation between symptom scores and eosinophils (P = 0.026, r = 0.52), and IgE (P = 0.001, r = 0.60) in the patients. No correlation was observed between symptom scores and ECP, IL-17, and IL-33 in the AR patient. Conclusions Patients with AR have significant higher serum levels of ECP, IL-17, and IL-33 than healthy controls. This indicates that these markers could be used to in order to diagnose AR and to monitor disease. Inhibitory molecules to IL-17 and IL-33 may be considered as novel treatment strategies.
