Summary
Owing to the great pollen sensitivity of some allergic patients and without effective pollen forecasting, it is often difficult to set a preventive therapy of pollinosis.
In 1987 and 1988 we compared the symptoms of 45 patients sensitive to grass pollen, daily pollen counts data recorded by a gravimetric and a volumetric sampler as well as meteorological data and observations of floral phenology.
Symptoms appeared to be strictly correlated with peak periods of pollen dispersion, but we observed allergic symptoms in our patients long before atmospheric pollen was detected by the pollen traps.
On the other hand, these early occurring symptoms seemed to be connected with the first Gramineae flowering.
