Aim-

• A study evaluated the role of miR-155 as a biomarker in AR
• It also assessed the association between its level and the total nasal symptom score (TNSS) and the levels of serum interleukin-4 (IL-4). 

Methods- 

• 90 children - 45 with pollen-induced AR and 45 healthy controls - were enrolled in the study.
• Quantitative real-time PCR was used to measure serum miR-155 expression levels.
• Human IL-4 ELIZA kits were utilized for the semiquantitative detection of the serum levels of IL-4.

Results-
