Further study details as provided by Kittipong Maneechotesuwan, Mahidol University:

Primary Outcome Measures:
  • Sputum eosinophils [ Time Frame: 8 weeks ]
    To determine the additive effect of simvastatin on airway inflammation in ICS-treated patients with persistent asthma by measuring eosinophil counts in induced sputum and on lung function (FEV1)

Secondary Outcome Measures:
  • Phosphorylated p38 MAPK in sputum cells [ Time Frame: 8 weeks ]
    1. To determine the additional effects of simvastatin in combination with inhaled corticosteroids on the expression of phosphorylated p38 MAPK and phosphorylated activating transcription factor (ATF)2 in induced sputum cells from asthmatic patients.
    2. To confirm the above in vivo results in the in vitro model using monocyte-derived dendritic cells.
    3. To determine the effects of simvastatin and/or corticosteroids on Th2 cytokine production by peripheral blood CD4+ T-lymphocytes in vitro.
