BACKGROUND: Allergic rhinitis is a common condition, with ragweed pollen one of the more prevalent aeroallergens. Environmental exposure units such as the Allergen BioCube(®) are valuable models for clinical allergy studies. A study was conducted to validate the Allergen BioCube for uniform ragweed pollen concentrations and clinically relevant sign and symptom responses to ragweed exposure. METHODS: Ragweed pollen concentrations were measured on 3 consecutive days in the Allergen BioCube and verified by Rotorod collection and continuous laser particle count measurements...

Aquagenic urticaria (AU) is a rare inducible form of physical urticaria, which occurs in response to cutaneous exposure to water, including sweat and tears. Patients present with characteristic 1-3 mm folliculocentric wheals with surrounding 1-3 cm erythematous flares within 20-30 minutes following skin contact with water. In rare cases, there are concomitant systemic symptoms, such as wheezing or shortness of breath. The pathogenesis of AU is poorly understood at this time, and it appears to be mediated in both a histamine-dependent and independent manner...

Chronic sphenoid rhinosinusitis is a spectrum of inflammatory diseases in isolated sphenoid sinus which may persist over a period of 12 weeks. It is a different entity from other types of rhinosinusitis because clinical presentations include headache, visual loss or diplopia, and patients may or may not have nasal obstruction or nasal discharge. Nasal endoscopic examination is useful, and computed tomography is mandatory. The disease requires comprehensive knowledge and appropriate imaging technique for diagnosis...

Exercise-induced anaphylaxis (EIAn) is defined as the occurrence of anaphylactic symptoms (skin, respiratory, gastrointestinal, and cardiovascular symptoms) after physical activity. In about a third of cases, cofactors, such as food intake, temperature (warm or cold), and drugs (especially nonsteroidal anti-inflammatory drugs) can be identified. When the associated cofactor is food ingestion, the correct diagnosis is food-dependent EIAn (FDEIAn). The literature describes numerous reports of FDEIAn after intake of very different foods, from vegetables and nuts to meats and seafood...

BACKGROUND: Low-dose theophylline has been recognized for its ability to restore histone deacetylase-2 activity which leads to improved steroid responsiveness and thus improved clinical outcome. We retrospectively evaluated the effect of low-dose theophylline therapy in pediatric patients hospitalized for an acute asthma exacerbation as a proof of concept study. METHODS: We compared patients who received low-dose theophylline (5-7 mg/kg/day) in addition to current standard of care to patients who were treated with current standard of care alone...

Hypersensitivity pneumonitis (HSP) is a common interstitial lung disease resulting from inhalation of a large variety of antigens by susceptible individuals. The disease is best classified as acute and chronic. Chronic HSP can be fibrosing or not. Fibrotic HSP has a large differential diagnosis and has a worse prognosis. The most common etiologies for HSP are reviewed. Diagnostic criteria are proposed for both chronic forms based on exposure, lung auscultation, lung function tests, HRCT findings, bronchoalveolar lavage, and biopsies...

Interleukin-5, an important cytokine in the pathophysiology of asthma, participates in terminal maturation and increases chemotaxis, endothelial adhesion, and activation of eosinophils. Blockade of interleukin-5 activity with monoclonal antibodies have been successful in decreasing eosinophil counts. Reslizumab, a monoclonal antibody that targets interleukin-5, has been studied for the treatment of severe asthma. Several studies have shown that reslizumab can effectively treat severe asthma with an eosinophilic phenotype...

Smoking is common in adults with asthma, yet a paucity of literature exists on smoking cessation strategies specifically targeting this subgroup. Adverse respiratory effects from personal smoking include worse asthma control and a predisposition to lower lung function and chronic obstructive pulmonary disease. Some data suggest that individuals with asthma are more likely than their non-asthmatic peers to smoke regularly at an earlier age. While quit attempts can be more frequent in smokers with asthma, they are also of shorter duration than in non-asthmatics...

BACKGROUND: Sublingual allergen immunotherapy is an effective treatment against allergic respiratory disease. Many studies have shown the safety of this type of therapy, although the factors that might affect the tolerability of high-dose sublingual immunotherapy have not been well established. The aim of this study was to determine the factors that affect the tolerability of sublingual allergen immunotherapy. PATIENTS AND METHODS: A total of 183 subjects aged ≥5 years, diagnosed with allergic rhinitis with/without mild to moderate asthma due to sensitization to grass, olive pollen, or mites, were included in this open, retrospective, multicentric, noninterventional study...

Lung macrophages link innate and adaptive immune responses during allergic airway inflammatory responses. Alveolar macrophages (AMs) and interstitial macrophages are two different phenotypes that differentially exert immunological function under physiological and pathological conditions. Exposure to pathogen induces polarization of AM cells into classically activated macrophages (M1 cells) and alternatively activated macrophages (M2 cells). M1 cells dominantly express proinflammatory cytokines such as TNF-α and IL-1 β and induce lung inflammation and tissue damage...

Upper and lower airways are considered a unified morphological and functional unit, and the connection existing between them has been observed for many years, both in health and in disease. There is strong epidemiologic, pathophysiologic, and clinical evidence supporting an integrated view of rhinitis and asthma: united airway disease in the present review. The term "united airway disease" is opportune, because rhinitis and asthma are chronic inflammatory diseases of the upper and lower airways, which can be induced by allergic or nonallergic reproducible mechanisms, and present several phenotypes...

The presence of eosinophilic inflammation is a characteristic feature of chronic and acute inflammation in asthma. An estimated 5%-10% of the 300 million people worldwide who suffer from asthma have a severe form. Patients with eosinophilic airway inflammation represent approximately 40%-60% of this severe asthmatic population. This form of asthma is often uncontrolled, marked by refractoriness to standard therapy, and shows persistent airway eosinophilia despite glucocorticoid therapy. This paper reviews personalized novel therapies, more specifically benralizumab, a humanized anti-IL-5Rα antibody, while also being the first to provide an algorithm for potential candidates who may benefit from anti-IL-5Rα therapy...

PURPOSE: A combination therapy with inhaled corticosteroid (ICS) and a long-acting β agonist (LABA) is the standard treatment for asthmatic patients, and step-down treatment is recommended once control has been achieved. However, little data exist that evaluate the long-term outcomes after step-down treatment. OBJECTIVE: To compare the long-term outcomes of step-down therapy with ICS/LABA or ICS alone for asthmatic patients who have achieved well-controlled asthma by the ICS (250 µg fluticasone)/LABA (50 µg salmeterol) combination (SFC, two puffs per day)...

Little is known about the features of asthma and allergy in the elderly. A significant number of elderly patients with asthma have uncontrolled and severe asthma. This review aims to provide an analysis of the literature on the assessment and phenotype of severe allergic asthma in the elderly. Gaps and pitfalls in diagnostic and therapeutic approaches, as well as management of severe allergic asthma in the elderly, are also discussed.
