Is the end of nasal sprays near? Will light therapy prevail?
While it looks like a space age laser, Allergia Medical’s new device uses light therapy to treat allergies. The photodynamic therapy using red light for 6 seconds per nostril daily was tested in a pilot study of 14 patients. There was a 31% improvement in patients’ “Total Nasal Symptom Score”, a validated questionnaire to help rate congestion and nasal allergy symptoms, in addition to no side effects being observed.
The image shown above is a prototype and will likely be improved. The photodynamic therapy works by:
- Reactive oxygen species in blood are suppressed after illumination possibly as a result of activation of superoxide dismutase or of catalase
- Visible and IR light cause changes in Ca2+ transport
- Allergic symptoms are largely dependent on oxygen radical formation and Ca2+ mobility
- Suppresses the effector phase
- Results in inhibition of histamine release and activity of neutrophils, eosinophils and mast cells
