To distinguish sinusitis from uncomplicated "colds," we examined lactoferrin and eosinophilic cationic protein (ECP) in nasal secretions obtained from 9 healthy adults, 9 adults with natural colds and 16 adults with sinusitis in USA Nasal washings from 32 previously healthy volunteers exposed to an experimental rhinovirus were also examined. Lactoferrin titres were >=1:400 in 4% of persons with uncomplicated colds and controls but in 79% of persons with sinusitis or purulent sputa.
