The socio-economic burden of allergic respiratory conditions is a huge problem especially for people with low income. This has become a big concern in continental Europe is even higher than that of mainstream diseases, such as diabetes and cardiovascular disease, as allergic rhinitis alone accounts for billions of Euros in healthcare expenses across Europe.

House dust mites (HDM) are one of the irritants that are the most common triggers behind allergic rhinitis and asthma. The role of probiotics in the treatment and prevention of some allergic conditions, such as atopic dermatitis, is already well recognized. Unfortunately, there is limited evidence about their efficacy in patients with respiratory allergies. Researches are being done to fill this research gap. This study was done to provide a narrative review of the house dust mite-related respiratory allergies and probiotics. This study holds significance as it can help to reduce the socio-economic burden of allergic respiratory conditions by recognising and controlling a trigger.

This study contributed to the existing knowledge body by providing current evidence for the use of probiotics in patients with allergic rhinitis and/or asthma is discussed.
