The efficiency of hypoallergenic space created with LG Puricare™ air purifier in the complex therapy of seasonal and perennial allergic rhinitis and bronchial asthma

Abstract

Background. To evaluate the efficacy and tolerability of a hypoallergenic space created with the LG Puricare air purifier, in a closed hospital ward and at home in the complex treatment of patients with exacerbation of perennial and seasonal allergic rhinoconjunctivitis with or without asthma. Materials and methods. 70 patients with seasonal and perennial allergic rhinoconjunctivitis with or without asthma were involved in the open comparative, randomized, placebo-controlled study conducted in 2 stages. At the 1st stage, an assessment of the efficacy and tolerability of hypoallergenic space created with LG Puricare™ air purifier in the hospital was performed. At the 2nd stage, the same study was performed at home space. The primary endpoint of the study was the evaluation of the total symptoms score. Secondary endpoints were changes in the parameters of peripheral blood, eye, and nasal secretion eosinophilia, external respiration function, peak flowmetry parameters. An assessment of indoor allergens, pollen and mold spores concentration, determination of the number of particle matter and evaluation of microbial and fungal air contamination in the environment were also carried out. Results. A significant reduction of the concentration of airborne particles and mold spores was demonstrated. Disease severity score showed significant clinical improvement but no changes in the parameters of the external respiration function, eosinophilia of blood, eyes and nasal secretions. Conclusion. The use of LG Puricare™ air purifier is recommended as a part of complex therapy of patients with various allergic diseases.
