Lactoferrin and Eosinophilic Cationic Protein in Nasal Secretions
of Patients with Experimental Rhinovirus Colds, Natural Colds, and
Presumed Acute Community-Acquired Bacterial Sinusitis
1:400 in 4% of persons with uncomplicated colds and controls but in 79% of persons with sinusitis or purulent sputa. ECP levels were >200 ng/ml in 61% of persons with
colds and >3,000 ng/ml in 62% of persons with sinusitis. Nasal
lactoferrin helps distinguish sinusitis from colds.
