Asthma-related impact of extending US parents' health insurance coverage to young adults.

IL-33 drives influenza-induced asthma exacerbations by halting innate and adaptive anti-viral immunity.

Influenza virus triggers severe exacerbations of asthma for which no adequate treatment is available. It is known that IL-33 levels correlate with exacerbation severity, but its role in the immune-pathogenesis of exacerbations has remained elusive.

C-reactive protein as a diagnostic tool in differential diagnosis of hypereosinophilic syndrome and ANCA-negative eosinophilic granulomatosis with polyangiitis.

Needs Assessment Survey for a Food Allergy Control Tool.

Validation of Asthma Control Assessment Among Urban Adolescents Using the Asthma Control and Communication Instrument (ACCI).

NIH guidelines recommend questionnaires to assess asthma control, but there are few self-reported asthma morbidity surveys validated among urban, African American, Hispanic and/or poor adolescents. The ACCI is a 12-item self-reported questionnaire previously validated among a diverse adult population, but not among adolescents.

Breakthrough cancer pain tailored treatment: which factors influence the medication choice? An observational, prospective and cross-sectional study in patients with terminal cancer.

Various options for the pharmacological treatment of breakthrough cancer pain (BTcP) are available. International guidelines on BTcP treatment are not univocal. A tailored treatment should be based on the assessment of different variables such as BTcP characteristics, oral mucositis, chronic rhinitis and a patient's ability to take medication.

Large endotracheal tumour presenting as severe COPD: flow-volume loop analysis, not always a straightforward diagnostic test.

The flow-volume loop (FVL) analysis is typically helpful in establishing the diagnosis of airway obstruction caused by endobronchial lesions. In this report, we describe a patient with emphysema and tobacco abuse who presented with chronic dry cough and severe chronic obstructive pulmonary disease (COPD) refractory to standard therapy. The initial FVL showed a relatively normal forced expiratory p...

IgE Test in Secretions of Patients with Respiratory Allergy.

IgE is a key player in multiple inflammatory airway diseases. Ample literature demonstrates its presence in mucosa of patients with allergic rhinitis (AR), local allergic rhinitis (LAR), asthma, or chronic rhinosinusitis with nasal polyposis (CRSwNP).

Curcumin as an anti-inflammatory agent: Implications to radiotherapy and chemotherapy.

Cancer is the second cause of death worldwide. Chemotherapy and radiotherapy are the most common modalities for the treatment of cancer. Experimental studies have shown that inflammation plays a central role in tumor resistance and the incidence of several side effects following both chemotherapy and radiotherapy. Inflammation resulting from radiotherapy and chemotherapy is responsible for adverse...

Detection of genuine grass pollen sensitization in children by skin testing with a recombinant grass pollen hybrid.

Skin testing represents a commonly used first diagnostic method in clinical practice but allergen extracts may vary in composition and often contain cross-reactive allergens and therefore do not always allow the precise identification of the sensitizing allergen source. Our aim was to investigate the suitability of a single recombinant hybrid molecule, consisting of the four major timothy grass po...

The Economic Burden of Pediatric Asthma in the United States: Literature Review of Current Evidence.

Asthma is a chronic respiratory disease that is widespread throughout the US population and disproportionately affects children. This literature review aimed to identify recent information regarding the economic burden of pediatric asthma in the US. MEDLINE, EMBASE, Econlit, and PsycINFO databases and gray literature sources were searched from January 2012 to January 2018 to capture relevant publi...

Advances in mechanisms of allergic disease 2017.

This review highlights advances in mechanisms of allergic disease, particularly type 2 innate lymphoid cells; T2 lymphocytes; B cells; dendritic cells: microbiome and barrier function; eosinophils, mast cells. During the last year, considerable progress has been made in the further characterization of type 2 inflammation controlled by both adaptive (T2) as well as innate (ILC2) effector cells. New...

Neuroplastic changes in the olfactory bulb associated with nasal inflammation in mice.

Rhinitis and rhinosinusitis are olfactory disorders caused by inflammation of the nasal passage and paranasal sinuses. Although chronic rhinosinusitis patients have smaller olfactory bulbs (OBs), there is limited knowledge regarding the influence of chronic nasal inflammation on OB neurons.

Identification of bee venom Api m 1 IgE epitopes and characterization of corresponding mimotopes.

Identification of Api m 1 IgE epitopes and characterization of their mimotopes described herein represents an important step towards better understanding of sting anaphylaxis pathogenesis and towards development of alternative immunotherapy for bee venom allergy.

Epithelial acid imbalance in eosinophilic esophagitis.

Rocuronium hypersensitivity: Does off-target occupation of the MRGPRX2 receptor play a role?

Inhibitory effects of bisdemethoxycurcumin on mast cell-mediated allergic diseases.

Most allergic reactions are induced by mast cell activation. Mast cells play vital roles in the pathogenesis of allergic diseases. Bisdemethoxycurcumin (BDMC), a natural curcuminoid, has potential anti-allergic effects. Hence, we explored the effect of BDMC on mast cell-mediated allergic diseases. The study proved that BDMC suppresses β-hexosaminidase release, granule release, and membrane ruffli...

Long-term exposure to ambient fine particles associated with asthma: A cross-sectional study among older adults in six low- and middle-income countries.

Ambient PM is considered harmful to the respiratory system. However, little has been shown about the long-term association between ambient PM and asthma.

Role of House Dust Mite-Derived Extracellular Vesicles in a Murine Model of Airway Inflammation.

House dust mite (HDM) is the major source of indoor allergens that cause airway disease. Recent evidence suggests that Gram-negative/positive bacteria produce nano-sized extracellular vesicles (EVs) containing diverse components, including various immunostimulatory molecules. However, the association between bacteria-derived EVs and development of airway disease is unclear.

Pediatric asthma: an unmet need for more effective, focused treatments.

Despite remarkable advances in our understanding of asthma, there are still several unmet needs associated with the management of pediatric asthma.

A pilot study to investigate the influence of upper respiratory infections on IgE reactivity to food allergens.

Food allergens are the most common triggers of anaphylactic cases during childhood, as documented in the European Anaphylaxis Registry (1). Recent data suggest that infections may act as augmenting factors in anaphylactic reactions, while their role in anaphylaxis induction during aeroallergen and oral immunotherapy procedures is well-documented (2). The proposed mode of action involves, in rather...

CD18 is redundant for the response to multiple vaccines: a case.

A first born boy to unrelated healthy Danish parents was presented with marked neutro- and lymphocytosis after birth (Table 1). His umbilical cord did not separate until age five weeks. Due to chronic skin infection (without pus formation) and protracted leucocytosis (haematological malignancy was excluded) he was referred to our university hospital at the age of 11 months This article is protecte...

Basidiomycetes-X, an edible mushroom, alleviates the development of atopic dermatitis in NC/Nga mouse model.

Basidiomycetes-X (BDM-X) is a novel edible mushroom recently identified as a new fungi species and is effective against oxidative stress and anti-inflammation associated with immune response. However the effect of BDM-X on atopic dermatitis (AD) has not been elucidated. In this study, we have investigated the effect of BDM-X on AD skin lesions in NC/Nga mouse model. AD-like lesion was induced by t...

From the Pages of AllergyWatch : January 2019.

Flow mediated vasodilation assay indicates no endothelial dysfunction in hereditary angioedema patients with C1-inhibitor deficiency.

Hereditary angioedema with C1 inhibitor deficiency (C1-INH-HAE) is a rare, potentially life-threatening disorder characterized by recurrent edematous attacks. The edema formation is the consequence of interaction of bradykinin and various vasoactive peptides with endothelium. Besides these agents, danazol, a modified testosterone derivative used in these patients to prevent edematous attacks, can ...
