CRS

Mayo Clinic yesterday received broad patent coverage for a new treatment of chronic rhinosinusitis (CRS), commonly called “sinus infection,” a disease that annually affects 32 million adults in the United States and currently has no Food and Drug Administration-approved treatment. Studies at Mayo Clinic have found the cause of CRS — a reaction to certain fungi — and demonstrated that the delivery of antifungal drugs directly into the nose and sinuses is safe and significantly reduces patients? symptoms. Improvements in asthma symptoms were noted in the same patient group. Past medical treatments for chronic sinus infections have been unsuccessful or produced severe side effects.
