Abstract
AIM
The main objective of the survey was to determine the frequency of the mono and polysensitizations in patients consulting for respiratory allergy, rhinitis or/and asthma. The secondary objectives were to evaluate the severity, the number and the type of the sensitizations, the frequency of the asthma or rhinitis as a function of the sensitizations, the evolution of the sensitizations with age, and identify the principal responsible pneumallergens.
PATIENTS AND METHODS
The multicentric survey included a patient questionnaire allowing the collection and anonymous treatment of data on socio-demographic characteristics, clinical symptoms, cutaneous tests and sensitizations.
RESULTS
A sample of 505 patients, mean age 24 years, consulting for rhinitis or asthma, monosensitized (36%) or polysensitized (64%), was evaluated. The percentage of polysensitized patients was similar in asthmatics, patients with rhinitis, and patients with both asthma and rhinitis (60%, 65%, and 63%, respectively). The mean number of the sensitizations was 2.4 for patients with asthma, 2.6 for those with rhinitis, and 2.6 for patients with both asthma and rhinitis. The greater the severity of the rhinitis or asthma, the higher the number of the sensitizations. Sensitizations to acarids, gramineae and cat were the most frequent. When practioners were asked about their intention to undertake desensitization in polysensitized patients, 52% of them replied positively.
CONCLUSION
Data collected during this survey showed that a large proportion of the patients who consulted for rhinitis or asthma were monosensitized (36%). Sensitization to acarids was the most frequent. Even in polysensitized patients, more than half the practioners said they would use desensitization.
