Most patients with allergic rhinitis are polysensitized. The efficacy of house dust mite (HDM) allergen immunotherapy (AIT) compared between monosensitized and polysensitized patients remains limited.
Physicians’ knowledge and practice which are consistent with evidence-based guidelines can improve allergic rhinitis (AR) patients’ care. Compared with western countries, the available literature about Asian doctors’ perceptions and clinical practices regarding Allergic Rhinitis and its Impacts on Asthma (ARIA) guidelines is limited.
Allergen immunotherapy is the only currently available treatment strategy that modifies the immune response to the causative allergen and induces clinical improvement and a steroid-sparing effect.
Daily intranasal corticosteroid (INCS) is recommended for treating allergic rhinitis (AR). Nevertheless, patients are generally not adherent and use it on-demand. The data on the efficacy of as-needed INCS was insufficient.
Pollen of grasses in Chloridoideae and Panicoideae subfamilies is a major source of grass group-1 allergens in tropical/subtropical areas. Previously, most studies of subtropical grass pollen allergens have focused on Cynodon dactylon (Bermuda grass-Chloridoideae) and Sorghum halepense (Johnson grass-Panicoideae). However, little information is available about allergenicity of pollen from Zoysia matrella (Manila grass or Zoysia grass-Chloridoideae), which is among the most popular turfgrasses in tropical/subtropical areas.
Asthma control has been shown to improve after clinical use of molecular-targeted biologic drugs. Although most patients have shown favorable responses to biologic drugs, some individuals need to switch to another biologic drug. To date, limited data are available regarding patients who received multiple biologic drugs.
A fexofenadine/pseudoephedrine combination tablet (F/P) is an optimal product for nasal obstruction. It contains fexofenadine hydrochloride, a histamine H1-receptor antagonist for sneezing and rhinorrhea and pseudoephedrine hydrochloride, an α-adrenergic agonist. The effect of an antihistamine-decongestant on nasal obstruction has been demonstrated in previous studies, but onset of action and efficacy data on nasal obstruction are limited.
Sensitization to the house dust mite (HDM) plays important roles in the development of allergic rhinitis (AR). Toll-like receptor 4 (TLR4) is a key initiator of the innate immune system upon exposure to environmental factors.
