Background: Chronic spontaneous urticaria (CSU) is a highly prevalent and difficult to manage cutaneous disease characterized by the presence of recurrent urticaria, angioedema, or both, for a period of 6 weeks or longer. One of the biological treatments used for patients with CSU with an autoimmune background and bad control of the disease is omalizumab, an anti-IgE monoclonal antibody. The understanding of the mechanism of action of this biological drug in CSU along with the identification of potential biomarkers of clinical response can be helpful in the personalized management of the disease.

Background: Some patients with severe asthma may benefit from treatment with biologics, but evidence has been mostly collected from randomized controlled trials (RCTs), in which patients' characteristics are different from those encountered in asthma patients in the real-world setting. The aim of this study was to describe the clinical features of complete responders versus non-complete responders to long-term treatment with biologics in patients with severe asthma attended in routine daily practice.
Methods: Data of a cohort of 90 patients with severe asthma who were treated with biologics (omalizumab, benralizumab, and mepolizumab) for at least 12 months and were followed up to March 2022.
A study was conducted in 98 adult patients diagnosed with severe eosinophilic asthma (73.5% women, mean age 47.2 years) and followed prospectively for 1 year.

The study objective was to determine the prevalence of immunoglobulin E (IgE) sensitization to specific cat and dog allergens using component-resolved diagnosis (CRD) in patients with allergic respiratory diseases plus cat and/or dog sensitization.
Methods: We included 87 patients aged 8-62 years, diagnosed with allergic asthma and/or rhinitis plus cat and/or dog sensitization, and attended at the allergy section of a tertiary hospital in Badalona (Catalonia, Spain).
Introduction: Although clinical trials have shown the efficacy and safety of allergen-specific immunotherapy (AIT) in the treatment of allergic asthma, there is a need for real-life studies. We aimed to assess the effectiveness and safety of a microcrystalline tyrosine-adjuvanted Dermatophagoides pteronyssinus allergoid (Acarovac Plus®) in patients with house dust mite (HDM)-induced allergic asthma in a real-life study.
Methods: A subanalysis of a multicenter, prospective, observational, real-life study.
Background: Despite the effectiveness of allergen immunotherapy (AIT), some patients are unresponsive for reasons still unknown; yet validated response biomarkers remain unavailable.
Objective: To analyze immunological parameters as biomarkers to monitor and predict clinical response to a MicroCrystalline Tyrosine-adjuvanted house dust mite (HDM) AIT in patients with allergic rhinitis (AR).
Methods: Observational, prospective, multicenter study including adult patients (aged 18-65 years) with AR, with and without asthma, sensitized to the HDM (DP) and prescribed Acarovac Plus® DP 100% in the routine practice.
Evaluate the effectiveness and safety of immunotherapy with Acarovac Plus in a 1-year prospective multicentered real-life study. A total of 118 adults with allergic rhinitis sensitized to received subcutaneous immunotherapy with Acarovac Plus. Treatment outcomes were evaluated at baseline, 6 months and 1 year after treatment initiation.

It is estimated that more than 30% of the world population is now affected by one or more allergic conditions and a high proportion of this increase is in young people. The diagnosis of allergy is dependent on a history of symptoms on exposure to an allergen together with the detection of allergen-specific IgE.

Objective: To assess the economic impact of the introduction of DuoResp(®) Spiromax(®) by focusing on a potential improvement in the inhalation technique to strengthen medication adherence for the treatment of moderate to severe asthmatics in Spain and five Spanish regions including Andalusia, Catalonia, Galicia, Madrid, and Valencia.
Methods: A 4-year budget impact model was developed for the period 2015-2018 from the Spanish Healthcare System perspective. Budesonide-formoterol fixed-dose combination delivered by Turbuhaler(®) was considered to be the most appropriate comparator for assessing the budget impact with the introduction of DuoResp(®) Spiromax(®).
Aim: A 1-year follow-up study comparing the safety and tolerability of the dosing schedules, satisfaction and effectiveness of a novel microcrystalline tyrosine-adsorbed mite (Dermatophagoides pteronyssinus)-allergoid subcutaneous immunotherapy (Acarovac Plus™) in 30 adult patients (18-65 years) with allergic rhinitis and/or asthma.
Materials & Methods: The effectiveness of the product was assessed by nasal provocation test measuring peak nasal inspiratory flow/symptoms, in vitro immunologic changes (IgE, IgG4 and IL-10) and Treatment Satisfaction Questionnaire for Medication.
Results: No adverse events were reported during dosing schedules.
Introduction: Allergen immunotherapy is a long-term treatment that has been associated with patient adherence issues. The aim of the study was to increase the knowledge on compliance of patients allergic to house dust mites, receiving sublingual immunotherapy (SLIT).
Methods: A retrospective observational study was performed in 53 Spanish allergy units.
Aim: To evaluate the efficacy of Dermatophagoides pteronyssinus (DPT) subcutaneous immunotherapy in allergic rhinoconjunctivitis patients.
Patients & Methods: This 17-week double-blind study randomized 136 patients (95 evaluable) to five dose groups of DPT depot extract (0.0625-0.

Background: Appropriate use of inhaled therapies for asthma and chronic obstructive pulmonary disease (COPD) is critical to ensuring good patient outcomes, efficient use of healthcare resources and limiting the effects of high-morbidity. The appropriate choice of inhaler and active therapy, incorporating patient preferences, can help improve treatment adherence and long-term outcomes. Despite this, many current inhalers are non-intuitive to use, and require extensive training.

A novel tyrosine-adsorbed, modified allergen product, Acarovac Plus, developed for the treatment of perennial mite allergy seeks to address the underlying cause of allergic rhinitis in this instance. One of two dosing regimens may be used, either the Conventional Regimen or the Cluster Regimen.

We aimed to assess treatment safety for patients with allergic rhinitis with or without asthma caused by Dermatophagoides house dust mites.
Methods: This observational study at 5 Spanish centers included 218 patients aged 4-64 years, of whom 117 were women and 122 were under 15 years old.
Rhodamine B and its five de-ethylated transformation products could be identified in a groundwater sample. Using high-performance thin-layer chromatography (HPTLC) six fluorescent zones were detected in the sample. In order to identify the compounds in the zones by exact mass mass spectrometry (MS) measurements and tandem mass spectrometry (MS/MS), they were extracted from the HPTLC plate for subsequent analysis by nano-chip high-performance liquid chromatography quadrupole-time-of-flight mass spectrometry (nano-chip HPLC/QTOFMS).

Aim: To evaluate patient perception of the onset of action and overall satisfaction with a fast-dissolving tablet (FDT) formulation of ebastine in patients with intermittent or persistent allergic rhinitis.
Patients And Methods: This was a cross-sectional, multicenter, pharmacy-based survey involving adult patients (>18 years) with allergic rhinitis who presented with a prescription for ebastine FDT. Via a telephone interview, patients were asked to evaluate the characteristics of ebastine FDT in comparison with their previous experience with other antihistamines.
