ABSTRACT
PURPOSE:
Interleukin (IL)-33, a member of the IL-1 cytokine family, is considered to be important for innate-type mucosal immunity of the lung and also has been suggested to induce Th2-type immune responses. We aimed to investigate if IL-33 is involved in airway inflammation due to respiratory syncytial virus (RSV) infection in young children.METHODS:
Thirty-eight infants ( or =2 of the following clinicalfindings:
hypoxemia (7 days of hospital stay. The levels of IL-33 and the IL-33 receptor (sST2) were measured using enzyme-linked immunosorbent assay in nasal secretion samples collected from the patients on admission and compared with 20 age-matched controls. We also investigated the levels of IL-33 and sST2 in relation to the atopic status and symptom severity of the patients.RESULTS:
Nasal IL-33 levels in the patients with acute RSV bronchiolitis were significantly increased (P<0.05), but sST2 showed no difference compared to the controls. Neither IL-33 nor sST2 showed significant difference in relation to the atopic status or severity of symptoms.CONCLUSION:
Our study showed significantly increased IL-33 in the nasal secretions of the young infants admitted with acute RSV bronchiolitis and suggests that IL-33 is involved in the pathogenesis of RSV-induced airway inflammation.
