| Résumé : | Since 1973, patients sensitized to grass pollen, have been requested to keep a symptom diary between May 15 and July 15. Symptoms were scored on a 0 to 3 graduated scale and the resulting curve was paralleled with the pollen survey obtained through a Hirst trap located at a height of 26 meters in the centre of the city of Brussels. These charts show there exists no constant connection between the two curves and that three distinct periods may be differentiated during which the apparent sensitivity of the patients is submitted to variations which are not closely bound to the amount of pollen in the air. There are a so-called period of « priming of the nasal mucosaduring which the sensitivity is greater than that which the pollen curves could account for, then during the first week of June, a brutal reaction, coincident with the sudden increase of pollen in the air and finally a period of apparent tolerance the effect of which is to moderate all the reactions. Nevertheless in those years when the rainfall was abnormally high (as in 1974 and 1977) the two curves do not exhibit the same concordance as those of the other years do. © 1978 Expansion Scientifique Française. |
