A retrospective study was carried out in 40 infants, age 1 to 24 months, with urticaria. Acute urticaria was seen most frequently (85%), followed by recurrent (10%) and chronic disease (5%). Several clinical features such as frequency of angioedema and hemorrhagic lesions appeared to be specific to urticaria in infants. An underlying cause was identified or suspected in 65% of cases: foods in 25%, and drugs and infections in 37.5%. Under 6 months of age, all infants had acute urticaria and 75% had cow's milk allergy. After 6 months of age, the main causes were drug intake (mostly aspirin and amoxicillin) and/or infections (mainly viral) (50%). Atopy was not overrepresented (20%), although a possible link between atopy and recurrent urticaria was noted. After a follow-up of 2 to 7.5 years, 96% of patients were symptom free. Thus, our results indicate that clinical and etiologic features of urticaria in infants are somewhat different from those of adults and children.

Une intervention précoce est souhaitable afin d’éviter l’installation d’une situation d’évitement très préjudiciable avec un retentissement social important et une douleur morale majeure. L’hypnose permet d’aborder la problématique sur un plan métaphorique, évitant de rentrer dans la logique de la focalisation de l’attention. La démarche thérapeutique passe par l’expérience d’une autre réalité de soi-même, avec réalisation d’un pont vers l’avenir et la « vraie vie ». Une autonomisation avec l’autohypnose est aidante si le patient adhère à cette technique.
