Detailed Summary:
Sponsor: Tehran University of Medical Sciences

Current Primary Outcome:

  • Change in SNOT-22 scores from Baseline [ Time Frame: 6 months ]
    At baseline and 6 months after treatment, all participants will complete the SNOT-22 questionnaire. SNOT-22 is a validated disease specific questionnaire that assesses the health related quality of life patients.
  • change in serum concentration of IL-10 [ Time Frame: 6 months ]
    At baseline and 6 months after treatment, serum level of IL-10 will be investigated for all participants.
  • change in concentration of serum TGF-beta [ Time Frame: 6 months ]
    At baseline and 6 months after treatment, serum level of TGF-beta will be investigated for all participants
  • change in concentration of serum IFN-gamma [ Time Frame: 6 months ]
    At baseline and 6 months after treatment, serum level of IFN-gamma will be investigated for all participants.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Lund Mackay score [ Time Frame: 6 months ]
    For all participants, Lund Mackay will be scored by investigators.
  • Asthma attacks [ Time Frame: 6 months ]
    Number of asthma attacks will be recorded for all participants over a 6-month follow up.
  • medication needs [ Time Frame: 6 months ]
    Medication needs to relief respiratory symptoms will be recorded for all participants over a 6-month period.
  • FEV1 [ Time Frame: 6 months ]
    FEV1 for all patients will be assessed using spirometery


Original Secondary Outcome: Same as current
