Advances in antioxidant phytochemical for inflammatory skin diseases: mangiferin and naringin nanocarriers based lipids

2020

Chronic inflammatory skin diseases are the most common topical disorders and the fourth cause of global disability. Among all, psoriasis (PS) and atopic dermatitis (AD) are the most frequent chronic and recurrent inflammatory diseases of the skin. Atopic dermatitis has a strong Th2 factor while psoriasis is a disease driven by Th17. The actual treatment, which involve the combination of topical, systemic and biological therapy, is characterized by numerous adverse effects, which reduce patient compliance, lead to the limitation of long-term use and limit the therapeutic efficacy. Therefore, there is a great need for the continuous development of novel, effective and safe coadjuvant treatmen…

Characterization of disease-specific cellular abundance profiles of chronic inflammatory skin conditions from deconvolution of biopsy samples

2019

Background Psoriasis and atopic dermatitis are two inflammatory skin diseases with a high prevalence and a significant burden on the patients. Underlying molecular mechanisms include chronic inflammation and abnormal proliferation. However, the cell types contributing to these molecular mechanisms are much less understood. Recently, deconvolution methodologies have allowed the digital quantification of cell types in bulk tissue based on mRNA expression data from biopsies. Using these methods to study the cellular composition of the skin enables the rapid enumeration of multiple cell types, providing insight into the numerical changes of cell types associated with chronic inflammatory skin c…

Management of allergic disease in the elderly: key considerations, recommendations and emerging therapies

2015

The number of people over 65 is increasing around the world. At present, between 5 and 10% of allergic diseases affect the elderly. In particular, rhinitis is increasing worldwide; the presence of high comorbidity makes the therapy of asthma even more complicated. With reference to dermatological allergies, the dryness of the skin favors the onset of allergic contact and atopic dermatitis, while the senescence of mucous membranes and the impaired secretion of polymeric IgA could be linked to food allergy. Overcoming the problem of adverse drug reaction is limited by the diagnostic difficulty in patients taking multiple drugs. In addition, some drugs, such as β-blockers, angiotensin-converti…

Associations between atopic diseases and the polymorphic systems ABO, Kidd, Inv and red cell acid phosphatase.

1979

In 239 German patients with atopic conditions (atopic dermatitis, hay fever, allergic rhinitis, bronchial asthma, and acute urticaria) the phenotype and gene distribution of 15 genetic blood polymorphisms (ABO, MNSs, rhesus, P, Kell, Duffy, Kidd, Hp, Gc, Gm, Inv, aP, PGM1, EsD, and 6-PGD) were analyzed and compared with those in 151 selected controls (individuals clinically free of allergic conditions and without allergy in the family history). The incidence of blood group antigens A and B was somewhat higher in patients than in controls. These observations are in accordance with the results of previous studies in other populations. In addition, our observations favor the hypothesis that th…

Noninvasive methods for the detection of upper and lower airway inflammation in atopic children

2006

Background Exhaled nitric oxide (FE NO ) and exhaled breath condensate (EBC) are noninvasive methods to assess inflammation. Objective To investigate the role of the FE NO and of the EBC pH and IL-5 levels in atopic children. Methods We evaluated oral and nasal FE NO and the pH and IL-5 of oral and nasal EBC in children with atopic dermatitis (AD; n=18), allergic rhinitis (AR; n=18), intermittent asthma (n = 21), moderate persistent asthma (n = 18), and healthy controls (HCs; n=16). Results Oral FE NO was significantly increased in asthma, whereas the nasal values were increased in AR and asthma in comparison with HCs. The pH of oral EBC was lower in AD and asthma than in AR and HCs, wherea…

Bronchial hyperresponsiveness in children with atopic rhinitis: a 7-year follow-up

2004

Background:  A high prevalence of bronchial hyperresponsiveness (BHR) was found in atopic subjects with rhinitis. Those subjects may be at higher risk for developing bronchial asthma. We evaluated, in a 7-year follow-up, BHR and atopy in a homogeneous population of nonasthmatic children with allergic rhinitis (AR), and their role in asthma development. Methods:  Twenty-eight children (6–15 years) with AR were studied. At enrollment (T0), skin tests, total serum IgE assay, peak expiratory flow (PEF) monitoring and methacholine (Mch) bronchial challenge were performed. BHR was computed as the Mch dose causing a 20% forced expiratory volume (FEV)1 fall (PD20FEV1) and as dose–response slope (DR…

How well do questionnaires perform compared with physical examination in detecting flexural eczema? Findings from the International Study of Asthma a…

2009

International audience; BACKGROUND: Questionnaires are widely used in epidemiological studies to measure eczema symptom prevalence, but there are concerns regarding their accuracy if used as a diagnostic tool. OBJECTIVES: To compare the performance of a validated eczema symptom questionnaire and a standardized skin examination protocol employed in the second phase of the International Study of Asthma and Allergies in Childhood (ISAAC). METHODS: A total of 30,358 schoolchildren aged 8-12 years from 18 countries were examined for flexural eczema. Parents also completed an eczema symptom questionnaire. We compared prevalence estimates at the population level based on the questionnaire vs. phys…

Atopic dermatitis and indoor use of energy sources in cooking and heating appliances

2012

Abstract Background Atopic dermatitis (AD) prevalence has considerably increased worldwide in recent years. Studying indoor environments is particularly relevant, especially in industrialised countries where many people spend 80% of their time at home, particularly children. This study is aimed to identify the potential association between AD and the energy source (biomass, gas and electricity) used for cooking and domestic heating in a Spanish schoolchildren population. Methods As part of the ISAAC (International Study of Asthma and Allergies in Childhood) phase III study, a cross-sectional population-based survey was conducted with 21,355 6-to-7-year-old children from 8 Spanish ISAAC cent…

The Development of the MeDALL Core Questionnaires for a Harmonized Follow-Up Assessment of Eleven European Birth Cohorts on Asthma and Allergies

2014

Background: Numerous birth cohorts have been initiated in the world over the past 30 years using heterogeneous methods to assess the incidence, course and risk factors of asthma and allergies. The aim of the present work is to provide the stepwise proceedings of the development and current version of the harmonized MeDALL-Core Questionnaire (MeDALL-CQ) used prospectively in 11 European birth cohorts. Methods: The harmonization of questions was accomplished in 4 steps: (i) collection of variables from 14 birth cohorts, (ii) consensus on questionnaire items, (iii) translation and back-translation of the harmonized English MeDALL-CQ into 8 other languages and (iv) implementation of the harmoni…
