Can you explain what is samter's triad syndrome?

Sampter's triad. "sampter's triad" or "triad asthma" is asthma that occurs in combination with Aspirin (or other nsaid) allergy and nasal polyps. It is believed that this condition results from an abnormal production of leukotrienes(inflammatorymediators /bronchoconstrictors). Many persons with this condition respond well to treatment with leukotriene blockers (singulair) or inhibitors (zyflo).
Samter's Triad. Samter's triad (aspirin exacerbated respiratory disease-aerd) is a chronic medical condition that consists of asthma, recurrent sinus disease with nasal polyps, and a sensitivity to aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs). There are various conservative treatments, but Aspirin desensitization by an allergist has proven helpful.
