“…Winter pollinosis should therefore be borne in mind, particularly in patients with hypersensitivity to fruit or a history of pollinosis caused by pollens of other Betulaceae trees, which cause respiratory symptoms in April or May in Paris (1,7,17). Of the diagnostic methods, the prick test is the simplest to do, but it has a relatively low positive predictive value.…”

“…The fruits or nuts most often implicated are hazelnut, apple, peach, kiwi, and strawberry. There is therefore an analogy with birch pollinosis (16), which is common both in Scandinavia and in the Paris area (7). Food-related reactions should, in our opinion, be sought routinely in patients with asthma attacks or spasmodic coryza during winter; such reactions are suggestive of hypersensitivity to alder or hazel pollen.…”

“…The main manifestations are rhinitis and asthma attacks, usually associated with bilateral conjunctivitis, between 15 May and 15 July (6). Birch (7), hornbeam, and ash pollinosis occurs earlier, at the beginning of spring. These three tree pollens cause respiratory symptoms similar to those caused by Poaceae, but the pollinosis of trees is usually distinguished by the time of onset.…”

Pollen is rarely investigated as a cause of winter respiratory symptoms. Infectious coryza and asthma are particularly common during winter, and it has been shown that environmental antigens can cause at least some cases in Paris. Recent experimental data from Calhoun et al. (1991) indicate that pollen may act synergistically with viral respiratory infections, which are particularly prevalent in winter. In the present study, we investigated, in 130 consecutive patients presenting with winter aggravation of asthma or rhinitis, winter pollinosis by skin test, radioallergosorbent test (RAST), and specific endonasal challenge test. Totals of 35, 24, and 21 patients reacted positively in skin, RAST (> 0.70 PRU/ml), and endonasal tests, respectively. Clinical features during the season established the diagnosis of winter pollinosis in 20 cases; it was due to alder pollen in 10 patients and hazel pollen in 12. The positive predictive value of the skin test was only 0.57, as compared with 0.86 for the specific endonasal test, which had a negative predictive value of 1. Our results indicate that hazel and alder pollens should be prick-tested for more often as causes of winter respiratory symptoms in Paris, even if similar manifestations were absent during previous winters, were previously present during spring or summer, or were both absent in previous winters and present in spring or summer.
