Perceived efficacy and satisfaction of patients with subcutaneous hypoallergenic high-dose house dust mite extract

Abstract

The efficacy and safety of subcutaneous immunotherapy with modified, high-dose, major allergen house dust mite extract is widely supported by double-blind, placebo-controlled studies. However, little is known regarding patient-perceived efficacy and satisfaction. An observational, retrospective, multicentre study in patients treated with Acaroid® was conducted to assess the efficacy and degree of satisfaction of the patients after the first six months of treatment with it. All the clinical study procedures were performed according to the routine clinical practice. This study demonstrates that Acaroid® is effective and well tolerated. The patients’ condition demonstrated a clear and marked improvement in the first 6 months after treatment initiation. Patients treated with Acaroid® were very satisfied, with a correlation to improvement in patient-perceived symptoms and the administration of treatment by a healthcare professional.
