BACKGROUND: Intralymphatic immunotherapy (ILIT) is a novel, faster alternative to conventional allergen immunotherapy (AIT). Few previous studies have evaluated its long-term effects. The objective of the present study was to complete a 5-year follow-up of a randomized double-blind placebo-controlled trial of ILIT for a combination of birch and grass allergens. METHODS: Fifty-eight patients with allergic rhinitis were treated with either placebo or a combination of ALK Alutard Birch and Grass 1000 SQ-U administered in 3 intralymphatic injections at 1-month intervals...

BACKGROUND AND OBJECTIVE: Allergic conjunctivitis is the most common type of ocular allergy. The objective of this study was to evaluate the efficacy of a new once-daily, preservative-free, bilastine 0.6% eye drop formulation for the treatment of allergic conjunctivitis. METHODS: Two double-masked, vehicle controlled, clinical studies (a Phase 2 Dose Ranging Study and a Phase 3 Efficacy Study) were conducted to assess the efficacy of bilastine ophthalmic solution for the treatment of signs and symptoms of allergic conjunctivitis...

BACKGROUND AND OBJECTIVE: Diagnostic criteria of chronic rhinosinusitis with nasal polyps (CRSwNP) include, among others, olfactory dysfunction (OD). We hypothesize that patients suffering with CRSwNP are good at self-assessing their sense of smell through visual analogue scale (VAS) compared to smell tests. METHODS: A controlled cross-sectional study was planned. Adults diagnosed with severe CRSwNP waiting for endoscopic sinus surgery were included. A cohort of healthy controls was also studied...

BACKGROUND: Smell impairment is more commonly related to chronic rhinosinusitis with nasal polyps (CRSwNP) than without, especially given associated asthma and/or NSAID-exacerbated respiratory disease and type 2 inflammation. Therapeutic options include intranasal and systemic corticosteroids, surgery and, more recently, biological therapy. We summarize current knowledge on the effect of biologics on olfaction in patients with CRSwNP. METHODS: We performed a systematic search of the PubMed and Cochrane databases from January 2001 to June 2022...

BACKGROUND AND OBJECTIVE: There are still gaps in the knowledge regarding the effectiveness of house dust mite (HDM) sublingual immunotherapy (SLIT) on allergic rhinitis (AR) and asthma (AA)-associated sleep disorders. A non-interventional study was conducted to assess the effect of the Standardized quality (SQ) HDM SLIT-tablet on safety and symptoms in adults with HDM respiratory allergies. The aim was to describe the status of insomnia and daytime sleepiness in AR and/or AA patients treated with the SQ HDM SLIT-tablet...

BACKGROUND AND OBJECTIVES: Cypress and olive pollen are the most prevalent sensitizer trees in the Mediterranean area. Some patients exhibit a dual sensitization which has not been well documented yet. To identify the allergens involved in the dual cypress and olive allergy (C+O) and study the relationship between phenotype and allergen sensitization. METHODS: C+O patients were selected. Monosensitized subjects to olive or cypress were used as reference. Specific IgE to whole extracts and purified allergens from olive and cypress were performed...

BACKGROUND: Pressurized metered-dose inhalers (pMDIs) exert an environmental impact resulting from CO2 emissions. Therapeutic alternatives with less environmental impact are widely used. Nevertheless, the choice of device and appropriate therapy should meet the clinical needs and the characteristics of the patient. OBJECTIVE: The primary objective was to estimate the impact of pMDIs prescribed for any indication on annual CO2 emissions in Spain.The secondary objective was to evaluate the potential impact of switching pMDIs to dry-powder inhalers (DPIs) in patients with asthma...
