Rhinoconjunctivitis severity induced by cat exposure influences early and late asthmatic responses: Evidence from an environmental exposure chamber
Abstract
Background
The impact of allergic rhinoconjunctivitis on the early (EAR) and late asthmatic response (LAR) has yet to be assessed during optimal allergen exposure conditions.
Objective
We aimed to assess predictive factors of the EAR and LAR and to evaluate the relation between rhinitis, conjunctivitis and asthma induced by cat allergen exposure in an environmental exposure chamber (EEC).
Methods
Data from two cohort studies involving asthmatic patients with cat allergy who performed a cat allergen exposure challenge in ALYATEC EEC were analysed. Spirometry, visual analogue scale (VAS) for asthma, VAS for rhinitis, Total Nasal Symptoms Score, Total Ocular Symptoms Score (TOSS), Rhinoconjunctivitis Total Symptoms Score and Abelson score were used to assess asthma, rhinitis and conjunctivitis during and after exposure.
Results
Correlation map between respiratory and rhinoconjunctivitis parameters in patients with an EAR during cat allergen exposure. |

The incidence of upper respiratory infections in children is related to the concentration of vanadium in indoor dust aggregates.
Abstract:
Background: It has been reported that the disease-initiated and disease-mediated effects of aerosol pollutants can be related to concentration, site of deposition, duration of exposure, as well as the specific chemical composition of pollutants.
Objectives: To investigate the microelemental composition of dust aggregates in primary schools of Vilnius and determine trace elements related to acute upper respiratory infections among 6-to 11-year-old children.
Methods: Microelemental analysis of aerosol pollution was performed using dust samples collected in the classrooms of 11 primary schools in Vilnius from 2016 to 2020. Sites included areas of its natural accumulation behind the radiator heaters and from the surface of high cupboards. The concentrations of heavy metals (Pb, W, Sb, Sn, Zr, Zn, Cu, Ni, Mn, Cr, V, and As) in dust samples were analyzed using a SPECTRO XEPOS spectrometer. The annual incidence rates of respiratory diseases in children of each school were calculated based on data from medical records.
A rare condition: montelukast allergy
Dindar Çelik F, Çelik Tuğlu H, Yağdıran M, Akkale Ö, Telli O, Aksu K. Eurasian J Pulmonol 2024;26:70-2.
Abstract
Montelukast, selective leukotriene (LT) receptor antagonist specific for cysteinyl LT type 1 receptors, serves as an alternative treatment option for asthma and different allergic clinical conditions. However montelukast, itself, may rarely induce hypersensitivity reactions. Although rare, clinicians, especially those working in pulmonology and allergy clinics, should be aware of the potential for montelukast to cause hypersensitivity reactions.
Herein, we present a 61-year-old female patient who was followed up with Samter’s syndrome and developed urticarial rashes after montelukast treatment, and montelukast allergy was confirmed by oral drug provocation test.

Allergen Component Testing: Key in Diagnosing Atypical Pollen-Food Allergy Syndrome
Abstract
This case report details the complex presentation, diagnosis, and management of a teenager with pollen-food allergen syndrome (PFAS), formerly known as oral allergy syndrome. PFAS, mediated by immunoglobulin E (IgE) antibodies, stems from the cross-reactivity between pollens and uncooked plant-based foods, leading to a spectrum of symptoms, such as itching or tingling of the oral cavity. A UK survey indicated an average PFAS prevalence of 2%, with apples, hazelnuts, and kiwifruit commonly implicated. The presented case involved a 15-year-old girl referred from the respiratory clinic to the allergy clinic due to episodes of sore throat and urticaria rash following Nutella (chocolate paste containing hazelnut) and peanut consumption.

Global assessment of the knowledge and confidence in managing allergic disorders among primary care pediatricians across Europe: An EAACI task force report
Cabrera M, Ryan D, Erlewyn-Lajeunesse M et al. Pediatr Allergy Immunol. 2024 Apr;35(4):e14116. doi: 10.1111/pai.14116.
Abstract
Background: Pediatricians are often the first point of contact for children in Primary Care (PC), but still perceive gaps in their allergy knowledge. We investigated self-perceived knowledge gaps and educational needs in pediatricians across healthcare systems in Europe so that future educational initiatives may better support the delivery of allergy services in PC.
Method: A multinational survey was circulated to pediatricians who care for children and adolescents with allergy problems in PC by the EAACI Allergy Educational Needs in Primary Care Pediatricians Task Force from February to March 2023. A 5-point Likert scale was used to assess the level of agreement with questionnaire statements. Thirty surveys per country were the cut-off for inclusion and statistical analysis.

Increased prevalence of autoimmune thyroid disease after COVID-19: A single-center, prospective study
Rossini A, Cassibba S, Perticone F et al. Front Endocrinol (Lausanne). 2023 Mar 8;14:1126683. doi: 10.3389/fendo.2023.1126683.
Abstract
Introduction: Thyroid dysfunctions associated with SARS-CoV-2 acute infection have been extensively described since the beginning of COVID-19 pandemics. Conversely, few data are available on the occurrence of thyroid autoimmunity after COVID-19 resolution. We assessed the prevalence of autoimmune thyroid disease (ATD) and thyroid dysfunctions in COVID-19 survivors three months after hospital admission.
Design and methods: Single-center, prospective, observational, cohort study performed at ASST Papa Giovanni XXIII Hospital, Bergamo, Italy. 599 COVID-19 survivors were prospectively evaluated for thyroid function and autoimmunity thyroperoxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb). When a positive antibody concentration was detected, thyroid ultrasound was performed. Multiple logistic regression model was used to estimate the association between autoimmunity and demographic characteristics, respiratory support, and comorbidities. Autoimmunity results were compared to a cohort of 498 controls referred to our Institution for non-thyroid diseases before the pandemic onset.
