Genetic Screening for Inflammation Response to Wood Smoke Particles
(SmokeScreen Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
Purpose: This screening protocol is designed to assess PMN (neutrophil) responsiveness to wood smoke particles (WSP) and the effect of the GSTM1 null genotype on this response. The researches will identify persons responsive and resistant to the inflammatory effect of WSP. It is anticipated that the GSTM1 genotype will be a risk factor for increased response to WSP.
Do I need to stop taking my current medications for the trial?
If you have mild persistent asthma, you must stop taking Singulair, inhaled corticosteroids, or cromolyn for 2 weeks before the study visits, except for using cromolyn before exercise. Other medications may be allowed if they don't interfere with the study and have been stable for a month.
Is wood smoke particle exposure safe for humans?
How does the treatment for inflammation response to wood smoke particles differ from other treatments?
This treatment is unique because it involves genetic screening to identify individuals who are more responsive to inflammation caused by wood smoke particles, allowing for personalized mitigation strategies. Unlike standard treatments, this approach focuses on understanding genetic factors like the GSTM1 genotype that may influence inflammation response.12678

Are You a Good Fit for This Trial?
This trial is for people aged 18-45 with mild asthma or allergies, who have good lung function and a low risk of cardiovascular disease. They must not smoke much, be willing to stop certain asthma medications temporarily, avoid caffeine before visits, and use reliable contraception if sexually active.Inclusion Criteria
