Allergic rhinitis, despite its high prevalence in the population, causes certain difficulties in diagnosis, since in children its clinical symptoms resemble those of an acute respiratory viral infection. In the presented clinical case, the diagnosis of allergic rhinitis was made 4 years late, and therefore the patient did not receive antiallergic treatment, which significantly complicated the course of the disease. To diagnose allergic rhinitis, a complex of anamnestic, clinical and laboratory research methods was used. The examination revealed a positive allergy history, early manifestations of atopy in the form of atopic dermatitis, living in an “allergenic” environment, and high levels of specific IgE antibodies to pollen and mite allergens. These data allow doctors to suspect the disease in children at an early age, verify the diagnosis together with an allergist, prescribe therapy and prevent the progression of the disease.
