ABSTRACT
Hyposensitization was carried out in 120 children aged 5 to 15 years with proven sensitivity to various pollen for 3 to 5 years before the start of the season. By reason of the results of intracutaneous tests 90 patients were treated with mixed pollen allergen and 30 patients with grass pollen allergen. A retrospective study was undertaken on the base of a questionnaire. Every year after the season duration and severity of symptoms as well as consumption of medicine were registered. The total success of hyposensitization amounted to 70.8% and this result varied on the one hand in dependence of the duration of disease on the other hand in dependence of the duration of treatment. A more inconvenient result was seen in those children who suffered from asthmatic symptoms exclusively compared to patients with hay fever. Local side effects resulted sporadically in 71.5% and systemic side effects in 15.7% by subcutaneous injection of depot-pollen allergen. Despite of extensive and not indifferent mode of treatment, hyposensitization should be performed in a correct way as soon as possible after exact indication.
