Rhinitis as a risk factor for depressive mood in pre-adolescents: a new approach to this relationship
2014
Background Respiratory allergic symptoms impact on social life and school activities, influencing the patient's mood states. We evaluated the relationships between allergic respiratory diseases and depressive/anxious mood in a large sample of Italian middle school students, using the partial directed acyclic graph (P-DAG). Methods We studied 1283 subjects aged 10–13. A health respiratory questionnaire including questions relevant to socioeconomic status (HCI) and a test for depression and anxiety were administered. All subjects performed spirometry and skin prick tests. Results A causal role of rhinitis on depression was found: the likelihood of being depressed increased from 11.2 to 17.7%,…
Association of Blattella germanica sensitization with atopic diseases in pediatric allergic patients
2011
To cite this article: La Grutta S, Cibella F, Passalacqua G, Cuttitta G, Liotta G, Ferlisi A, Viegi G. Association of Blattella germanica sensitization with atopic diseases in pediatric allergic patients. Pediatr Allergy Immunol 2011; 22: 521–527. Abstract Background: The extent to which the sensitization to the German cockroach Blattella germanica (BG) affects onset/presence of rhinoconjunctivitis (RC) in children is unknown. Objectives: The present work was aimed to assess the prevalence of BG sensitization in an outpatient pediatric population from an allergy clinic, the association with allergic diseases, and the effect of age in children with allergic sensitization. Methods: Five hu…
Antiasthmatic effects of gamma linolenic acid -high dose Evening Primrose Oil and Borage Oil stimulate allergen tachyphylaxis of sensitized guinea pi…
2012
Summary Evening primose oil (EPO) and borage oil (BO), which contain high amounts of gamma linolenic acid (10% or 20%) and are described to stimulate prostaglandin E biosynthesis, were investigated in guinea pigs for their ability to stimulate an important active self protecting mechanism against allergens (“allergen tachyphylaxis”). Groups of 12 guinea pigs sensitized to ovalbumin were fed over five days with either EPO or BO (100mg/kg/day or 1 g/kg/day) prior to sequential allergen inhalation challenges (time 0′, 10′, 20′, 60′, 70′ and 80′). Bronchial obstruction was measured by whole body plethysmography. 100 mg/kg EPO did not alter the bronchial reactions of the animals; 100 mg and 1 g/…
Should atopy be assessed in elderly patients with respiratory symptoms suggestive of asthma?
2010
Aging is associated with modifications of the immune system and this could contribute to a reduced prevalence of allergic disease in the elderly. Atopy has rarely been considered in the clinical assessment of the geriatric respiratory patient. This article is a review of the available literature assessing the impact of age on atopy in the asthmatic patient. In the majority of papers, we found a lower prevalence of atopy in the most advanced ages, both in healthy subjects and in individuals affected by allergic respiratory diseases. No large, longitudinal studies performed in the general population have been conducted to confirm this observation. Although available data seem to favor the dec…
A cross-sectional study assessing the relationship between BMI, asthma, atopy, and eNO among schoolchildren
2011
Increased body weight may influence airway inflammatory mechanisms.To assess whether overweight-obesity (OW-O), evaluated as increased body mass index, is associated either with exhaled nitric oxide (eNO), a marker of airway inflammation, or with allergic sensitization in a large sample of children and adolescents.A cross-sectional, epidemiological study was performed on a population sample of schoolchildren evaluating 708 subjects (age 10-16 years; BMI 13-39 kg/m(2)) by respiratory health questionnaire, skin prick tests, spirometry, and eNO measure.Prevalence rates were: OW-O 16.4%, asthma ever (A) 11.9%, and rhinoconjunctivitis (RC) 14.8%. Asthma ever and allergic sensitization were signi…
Determinants of Allergic Sensitization, Asthma and Lung Function: Results from a Cross-Sectional Study in Italian Schoolchildren
2020
Prenatal smoking exposure and early-life respiratory infections are major determinants of asthma during childhood. We investigate the factors influencing allergic sensitization (AS), asthma, and lung function in children and the balance between individual and environmental characteristics at different life stages. 1714 children aged 7&ndash
IL-17 and TNF-α Are Key Mediators of Moraxella catarrhalis Triggered Exacerbation of Allergic Airway Inflammation
2017
Alterations of the airway microbiome is often associated with pulmonary diseases. For example, detection of the bacterial pathogen Moraxella catarrhalis in the upper airways is linked with an increased risk to develop or exacerbate asthma. However, the mechanisms by which M. cattarhalis augments allergic airway inflammation (AAI) remains unclear. We here characterized the cellular and soluble mediators of M. catarrhalis triggered excacerbation of AAI in wt and IL-17 deficient as well as in animals treated with TNF-alpha and IL-6 neutralizing antibodies. We compared the type of inflammatory response in M. catarrhalis infected, HDM-allergic and animals infected with M. catarrhalis at differen…
Allergic sensitization to common pets (cats/dogs) according to different possible modalities of exposure: an Italian Multicenter Study
2018
Abstract Background The query “are there animals at home?” is usually administered for collecting information on anamnesis. This modality to consider exposure to pet allergens constitutes a potential bias in epidemiological studies and in clinical practice. The aim of our study was to evaluate/quantify different modalities of exposure to cat/dog in inducing allergic sensitization. Methods Thirty Italian Allergy units participated in this study. Each centre was required to collect the data of at least 20 consecutive outpatients sensitized to cat/dog allergens. A standardized form reported all demographic data and a particular attention was paid in relieving possible modalities of exposure to…
The effect of residential urban greenness on allergic respiratory diseases in youth: A narrative review
2020
Abstract Background Environmental exposures across the life course may be a contributor to the increased worldwide prevalence of respiratory and allergic diseases occurring in the last decades. Asthma and rhinoconjunctivitis especially contribute to the global burden of disease. Greenness has been suggested to have beneficial effects in terms of reduction of occurrence of allergic respiratory diseases. However, the available evidence of a relationship between urban greenness and childhood health outcomes is not yet conclusive. The current review aimed at investigating the current state of evidence, exploring the relationship between children's exposure to residential urban greenness and dev…
