Stress, pseudoallergens, autoimmunity, infection and inflammation in chronic spontaneous urticaria

  • Review
  • Open Access

Abstract
Mast cell activation in acute and chronic spontaneous Urticaria
Chronic spontaneous urticaria (CSU) is often associated with organ specific autoimmunity but is rarely caused by food allergy. Colourings and preservatives in pre-packaged foods, so called pseudoallergens, have also been implicated. Factors that promote inflammation or reduce anti-inflammatory mechanisms may however, predispose susceptible individuals to CSU. Chronic underlying infection and mental and emotional stress can sometimes precede the onset of CSU and once established can exacerbate the symptoms.

Contraindications to immunotherapy: a global approach

  • Review
  • Open Access
Abstract
Conflicting guidelines on whether a condition/comorbidity
consists absolute, relative or no contraindication to SCIT
Background
Recommendations on contraindications to allergen immunotherapy (AIT) have been independently developed by National and International Societies/Academies. AIT contraindications are mainly based on case reports, case-series, or experts’ opinion, while evidence-based information is limited. The aim of the present review was to describe existing guidelines on contraindications to AIT and to highlight differences between them.
Main body

A randomized, placebo-controlled, double-blinded, single-centre, phase IV trial to assess the efficacy and safety of OM-85 in children suffering from recurrent respiratory tract infections

Via a randomized, placebo-controlled, double-blind, single-centre, phase IV trial conducted in Italy, researchers further added to the assessment of the role played by OM-85, a lysate of 21 common bacterial respiratory pathogens, in the prevention of recurrent respiratory tract infections (RTIs) in children. Among patients receiving OM-85 for 3 months vs those given placeboes, the number of RTIs and of children who experienced at least one RTI were significantly lower. For upper RTIs, variations were statistically important. In the group with children treated with OM-85 for 3 months vs the placebo group, days of absence from daycare for children and working days lost by parents were significantly lower.

The Explosion of OTC Management of Allergic Rhinitis: Costs and Risks

    Abstract
    Purpose of the Review
    To review self-medication and the increasing use of over-the-counter (OTC) medications in the treatment of allergic rhinitis in the last years.
    Recent Findings
    Thanks to recent research and the use of mHealth tools, the preferences of patients, the role of primary care physicians, pharmacists, and specialists in the management of this prevalent condition have been known.
    Summary
    Successful self-management of AR requires that patients be fully informed about the available treatment options, the proper use of nasal spray devices, the need for therapy based on prevention, and avoidance of allergens. The use of OTC medications facilitates access to treatment and lowers health costs, but requires education of patients, and advice from the pharmacist, the primary care physician and, occasionally, the specialist to ensure its effectiveness and avoid under-diagnosis, multimorbidities, sub-treatment, and adverse events.

    Lung ultrasound in infants with bronchiolitis

    BMC Pulmonary Medicine

    Abstract

    Lung ultrasound (LUS) is nowadays a fast-growing field of study since the technique has been widely acknowledged as a cost-effective, radiation free, and ready available alternative to standard X-ray imaging. However, despite extensive acoustic characterization studies and documented medical evidences, a lot is still unknown about how ultrasounds interact with lung tissue. One of the most discussed lung artifacts are the B-lines [in all ages] and the subpleural consolidations (in young infants). Recently, LUS has been claimed to be able to detect pneumonia in infants with bronchiolitis, although this can be an overestimation due to the peculiar physiology of small peripheral airways of the pediatric lung (particularly in neonate/infants).

    Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology*

    Logo of anaisbrasdermInstructions for authorsPrevious IssuesSubmit a manuscriptAnais Brasileiros de Dermatologia
    . 2019 Mar-Apr; 94(2 Suppl 1): 67–75.

    ABSTRACT
    BACKGROUND
    Consensus-based recommendations of topical and systemic
    treatments for patients with atopic dermatitis (AD)
    Atopic dermatitis is a highly prevalent inflammatory and pruritic dermatosis with a multifactorial etiology, which includes skin barrier defects, immune dysfunction, and microbiome alterations. Atopic dermatitis is mediated by genetic, environmental, and psychological factors and requires therapeutic management that covers all the aspects of its complex pathogenesis.
    OBJECTIVES
    The aim of this article is to present the experience, opinions, and recommendations of Brazilian dermatology experts regarding the therapeutic management of atopic dermatitis.

    Psychiatric comorbidity in chronic urticaria patients: a systematic review and meta-analysis


    Review - Open Access
    Gerasimos N. Konstantinou & George N. Konstantinou

    Clinical and Translational Allergy volume 9, Article number: 42 (2019) 

    Abstract
    Background

    Dermatological illness can affect the quality of life and may coexist with psychiatric disorders.
    Objective
    The aim of this review was to systematically evaluate the published evidence of any psychiatric disorders that may coexist with chronic urticaria (CU) and any effect psychiatric interventions may have on CU.
    Methods
    Following the Cochrane guidance, we conducted a systematic literature search using web-based search engines provided by PubMed (for Medline database), Google Scholar and Scopus for studies that have investigated the existence of psychiatric comorbidity in patients with CU.

    Pneumococcal vaccination responses in adults with subnormal IgG subclass concentrations

    • Research article
    • OPEN ACCESS
    Abstract
    Background
    We sought to compare Pneumovax®23 responses in adults with subnormal IgG subclass concentrations. We studied adults with normal total IgG, frequent/severe respiratory infection, and subnormal IgG1, IgG3, or IgG1 + IgG3 before and after Pneumovax®23. We defined response as serotype-specific IgG > 1.3 μg/mL and aggregate response as IgG > 1.3 μg/mL for ≥70% of all serotypes tested. We compared patients with and without serotype-specific responses and performed logistic regression on aggregate responses using: age; male sex; body mass index; autoimmune condition(s); atopy; other allergies; subnormal IgGSc immunophenotypes; IgA; and IgM.

    Background
    Atypical manifestations, such as elevated serum immunoglobulin-G4 (IgG4) and extra-pulmonary IgG4 positive plasmacyte infiltration, have been described in patients with eosinophilic granulomatosis with polyangiitis (EGPA), such complicated situation might not be readily differentiated from IgG4-related disease.

    Early antibiotic exposure and development of asthma and allergic rhinitis in childhood

    . 2019; 19: 225.
    Published online 2019 Jul 5. doi: 10.1186/s12887-019-1594-4
    Abstract
    Background
    The prevalence of pediatric allergic diseases has increased rapidly in the United States over the past few decades. Recent studies suggest an association between the increase in allergic disease and early disturbances to the gut microbiome. The gut microbiome is a set of intestinal microorganisms that begins to form during birth and is highly susceptible to disturbance during the first year of life. Early antibiotic exposure may negatively impact the gut microbiota by altering the bacterial composition and causing dysbiosis, thus increasing the risk for developing childhood allergic disease.
