BACKGROUND: In humans, both basophils and dendritic cells (DCs) express the high affinity IgE receptor (FcεRI). OBJECTIVE: To gain more insight in the relation between serum IgE levels and FcεRI expression and IgE binding by DCs and basophils in house dust mite (HDM) allergy and during subcutaneous immunotherapy (SCIT). METHODS: We measured FcεRI, IgE and HDM allergen on DCs (conventional type 2 DCs, cDC2s; plasmacytoid dendritic cells, pDCs) and basophils by flow cytometry in 22 non-allergic versus 52 allergic subjects, and upon HDM SCIT in 28 allergic subjects...

The clinical distinction of chronic respiratory rhinitis appears to confirm the evo-devo theory of the three noses. The authors report two cases of advanced allergic rhinitis, in which chronic inflammation had induced a violaceous colour of the mucosa of the respiratory nose and a whitish polypoid appearance of the free edge of the middle turbinate. Nose and paranasal sinus CT scan revealed, beyond the virtual nasal cavities observed on nasal endoscopy and CT imaging, normal radiolucency or only minor opacities of the ethmoid (i...

BACKGROUND: Lifetime lung function is related to quality of life and longevity. Over the lifespan, individuals follow different lung function trajectories. Identification of these trajectories, their determinants, and outcomes is important, but no study has done this beyond the fourth decade. METHODS: We used six waves of the Tasmanian Longitudinal Health Study (TAHS) to model lung function trajectories measured at 7, 13, 18, 45, 50, and 53 years. We analysed pre-bronchodilator FEV1 z-scores at the six timepoints using group-based trajectory modelling to identify distinct subgroups of individuals whose measurements followed a similar pattern over time...

REVIEW

Although nasal hyperreactivity (NHR) is a common feature in patients suffering from allergic and non-allergic rhinitis, it is widely neglected during history taking, underdiagnosed in the majority of patients with rhinitis and rhinosinusitis, not considered as an outcome parameter in clinical trials on novel treatments for rhinitis and rhinosinusitis, and no target for routine treatment. In contrast to the simple nature of diagnosing NHR by a history of nasal symptoms induced by non-specific exogenous and/or endogenous triggers, quantification is hardly performed in routine clinic given the lack of a simple tool for its diagnosis...

INTRODUCTION: NATESTO® testosterone nasal gel (TNG) is a liquid gel that is applied in the nose for the treatment of male hypogonadism. There is a reasonable concern that administration of TNG to patients with active rhinitis could modify absorption. Results from two clinical studies are reported wherein subjects with allergic rhinitis (AR) subjects are treated with TNG. METHODS: The 24-hour pharmacokinetics (PK) and relative bioavailability of serum total testosterone (sTT) from TNG (11 mg tid ) were determined using a phase 1 Latin-square design with 18 eugonadal AR subjects crossed over between asymptomatic, symptomatic-untreated, and symptomatic-treated (oxymetazoline) conditions...

BACKGROUND: Specific immunotherapy is the only causal treatment in respiratory allergy. Due to high treatment cost and possible severe side effects subcutaneous immunotherapy (SCIT) is not indicated in all patients. Nevertheless, reported treatment rates seem to be low. This study aims to analyze the effects of increasing treatment rates of SCIT in respiratory allergy in terms of costs and quality-adjusted life years (QALYs). METHODS: A state-transition Markov model simulates the course of disease of patients with allergic rhinitis, allergic asthma and both diseases over 10 years including a symptom-free state and death...

Nasal cytology represents a useful, inexpensive and easy-to-apply diagnostic method to better detail the phenotypic characteristics of rhinitis. In fact, it allows to detect and quantify the cell population within the nasal mucosa at a given time. The technique involves sampling, processing and microscope reading. Sampling requires the collection of cells from the surface of nasal mucosa that is usually done by a sterile disposable curette. Samples should be collected from the middle portion of the inferior turbinate where the ratio ciliate/mucinous cells is expected to be well balanced...

Allergic rhinitis (AR) is mediated by many proinflammatory and anti-inflammatory cytokines as interleuhin-17 (IL-17) and interleukin-35 (IL-35) respectively. We assessed the effect of allergen specific immunotherapy (IT) on the serum levels of IL-17 and IL-35 in patients with AR sensitive to house dust mites (HDMs). Twenty patients with AR sensitive to HDMs and ten healthy control subjects were included in the study. Sensitivity to HDMs was diagnosed by positive skin prick test. Patients were treated by cluster IT...
