Background: Allergic rhinitis (AR) is characterized by an inflammatory reaction. High-mobility group box-1 protein (HMGB1) has many characteristics similar to classic proinflammatory cytokines. No study has yet investigated its role in AR. The aim of this study was to measure HMGB1 levels in the fluid recovered from nasal lavage in children with untreated AR and in control subjects. Materials: The study was conducted on 104 AR subjects (48 males and 56 females, median age 10.3 ± 3.4 years) and 97 healthy children (42 males and 55 females) who were age-matched (median age 9.8 ± 4.1 years). Total serum immunoglobulin E, peripheral eosinophils and nasal symptoms assessed by visual analog scale (VAS) were considered. HMGB1 was measured using an ELISA assay. Results: HMGB1 levels in nasal lavage fluid were higher in AR children than in the control group (96.9 ± 19.3 vs. 9.27 ± 4.01 ng/ml; p <0.001). There was a very strong relationship between HMGB1 levels and VAS values in AR children (r = 0.919). Considering the symptom severity assessed by VAS, there was a relationship between HMGB1 and VAS in all AR subgroups: more evident in the severe subgroup (r = 0.727). Conclusions: Nasal HMGB1 has significantly increased in children with AR and is significantly related to symptom severity.
