  1. Immunotherapy Personal statistics John Weisnagel, M.D.

  2. Database • Sept 1992-June 2006: 23,577 patients • Undergoing immunotherapy: 2,393 pts (10.14%) • Perennial Rx (all-year long): 1,437 (60%) • Pre-seasonal Rx (one injection per week 1-2 months preceding the specific pollen season): 936 (39.1%) • 20 pts having rec’d both types of treatment.

  3. Efficacy of immunotherapy • Of the 2,393 treated since 1992, • 983 replied to the question of the effect of their treatment (excellent, very good, good, slight or no change) when reminders were sent them about renewals • Treatment was either: • Perennial or • Pre-seasonal.

  4. Perennial Treatment • 581 patients: • Asthma: 53 (9.12%) • Asthma + pollinosis: 74 (12.7%) • Asthma + rhinitis: 83 (14.2%) • Pollinosis: 148 (25.47%) • Rhinitis: 223 (38.38%)

  5. Efficacy of Perennial treatment in 581 patients

  6. Pre-seasonal Treatment • 402 patients: • Asthma + pollinosis: 6 (1.4%) • Asthma + rhinitis: 2 (0.49%) • Pollinosis: 393 (97.76%) • Rhinitis: 1 (0.29%)

  9. Efficacy summary

  10. Pre-seasonals • Center-Al™ • Suspal™ • Pollinex R™ • Other tyrosine preps.

  11. Perennials • Mixtures: • House dust mite + pollens • House dust mite + molds • House dust mite + pollens + molds

  12. Bottom line • These personal statistics, though anecdotal, reflect the conclusion of the many studies published on the benefit of immunotherapy. • Both forms of therapy, perennial and pre-seasonal have similar benefits. • Immunotherapy is still an effective treatment in respiratory allergy, and should be considered when pharmaceutical therapy is inadequate.
