Importance: Asthma affects about 7.5% of the adult population. Evidence-based diagnosis, monitoring, and treatment can improve functioning and quality of life in adult patients with asthma. Observations: Asthma is a heterogeneous clinical syndrome primarily affecting the lower respiratory tract, characterized by episodic or persistent symptoms of wheezing, dyspnea, and cough. The diagnosis of asthma requires these symptoms and demonstration of reversible airway obstruction using spirometry...

BACKGROUND AND PURPOSE: Cysteinyl leukotrienes (CysLTs) are pro-inflammatory lipid mediators that exacerbate disease state in several asthma phenotypes including asthma induced by allergen, virus and exercise. However, the role of CysLTs in irritant-induced airway disease is not well characterized. The purpose of the current study was to investigate the effect of montelukast (MK), a CysLT1R antagonist, on parameters of irritant-induced asthma (IIA) induced by inhalation of chlorine (Cl2 ) in the mouse...

A 62-year-old man with asthma presented with a 1-month history of wheezing and exertional dyspnea. Although the wheezing symptoms disappeared after systemic corticosteroid therapy, the exertional dyspnea and hypoxemia did not improve. A diagnosis of intravascular large B-cell lymphoma (IVLBCL) with pulmonary involvement was suspected because of the increased serum lactic dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL-2R) level, increased alveolar-arterial oxygen difference (AaDO2), decreased pulmonary diffusing capacity for carbon monoxide (DLCO) and scintigraphic, computed tomography (CT) and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT findings...

15-deoxy-Δ-12,14-prostaglandin J2 (15d-PGJ2) has been described as an anti-inflammatory lipid mediator in several in vitro and in vivo studies, but its effect on allergic pulmonary inflammation remains elusive. The aim of this study was to investigate the therapeutic potential of 15d-PGJ2 based on distinct murine models of allergic asthma triggered by either ovalbumin (OVA) or house dust mite extract (HDM). Characteristics of lung inflammation, airway hyper-reactivity (AHR), mucus exacerbation, and lung remodeling in sensitized A/J mice treated or not with 15d-PGJ2 were assessed...

Michael S Schechter
As technology yields new treatments, pediatric pulmonologists need determine how best to use them and how to decide which ones are best for any specific group or individual patient. Physicians have always customized therapies based upon patient response, but the new concept of "Personalized (or precision) medicine" focuses attention to a greater degree on the individual needs of patients based on their genetic, biomarker, phenotypic, or psychosocial characteristics. The newly developed biologics for treatment of asthma and CFTR modulators for treatment of cystic fibrosis (CF) highlight this newer approach...

BACKGROUND: Breath-actuated inhalers (BAI) eliminate the need for hand-breath coordination and, therefore, simplify thedelivery of inhaled medication. OBJECTIVE: To evaluate the efficacy and safety of beclomethasone dipropionate BAI and metered-dose inhaler (MDI) versus placebo in pediatric patients ages 4-11 years with persistent asthma. METHODS: In this double-blind, double-dummy, phase III study, 628 children with persistent asthma were randomly assigned(1:1:1:1:1) to twice-daily beclomethasone dipropionate (BAI 80 micrograms/day, BAI 160 micrograms/day, MDI 80 micrograms/day, or MDI 160 micrograms/day) or to placebo...

PURPOSE: Rates of nonadherence to asthma treatment in Spain are between 24% and 76%, which results in poor disease control and increased health care costs. The main objective of this multidisciplinary consensus was to investigate the opinions of health professionals and patients regarding adherence to inhaled therapy in Spain. The results will help to identify the causes of nonadherence and to establish strategies to detect and correct the problem. METHODS: This research was conducted by using a modified Delphi method organized into 2 rounds and involving a panel of 64 physicians, 16 nurses, and 10 community pharmacists...

Fred Wise (1881-1950) and Marion Sulzberger (1895-1983) are often credited with introducing the term atopic dermatitis to dermatology in 1933. This definition was based on atopy, a term first created by Arthur Coca (1875-1959) and Robert Cooke (1880-1960) in 1923, when they recognized an association between allergic rhinitis and asthma. Despite its recent introduction into our medical lexicon, historical precursors of atopic dermatitis date back to at least as early as 69-140 ce. In this contribution, we highlight both the prominent individuals credited with shaping the disorder into our current interpretation and the suspected historical precursors of this disease and reported treatments...

INTRODUCTION: Asthma is the most common chronic respiratory disease in children and inhaled corticosteroids (ICS) constitute the first line of treatment for these patients. However, the potential growth-inhibiting effect of ICS has often been a cause of concern for both caregivers as well as physicians, and there still remains conflict regarding their safety profile. OBJECTIVE: To assess whether the administration of ICS in low or medium doses is associated with height reduction in prepubertal children...

OBJECTIVE: Bronchial thermoplasty (BT) as an add-on therapy for uncontrolled severe asthma is an alternative to biologic therapies like omalizumab (OM). We conducted an indirect treatment comparison (ITC) to appraise comparative effectiveness of BT and OM. METHODS: A systematic literature review identified relevant randomized controlled trials. The ITC followed accepted methodology. RESULTS: The ITC comprised a sham-controlled trial of BT (AIR2) and two placebo-controlled trials of OM (INNOVATE; EXTRA)...

INTRODUCTION: Comparative data on the burden of atopic dermatitis (AD) in adults relative to the general population are limited. We performed a large-scale evaluation of the burden of disease among US adults with AD relative to matched non-AD controls, encompassing comorbidities, healthcare resource utilization (HCRU), and costs, using healthcare claims data. The impact of AD disease severity on these outcomes was also evaluated. METHODS: Adult AD patients in the Commercial (n = 83,106), Medicare (n = 31,060), and Medi-Cal (n = 5550) databases were matched (1:1) to non-AD controls by demographic characteristics...

High resolution computed tomography (HRCT) is a well-established imaging technology to measure lung and airway morphology in vivo. However, there is a surprising lack of studies examining HRCT reproducibility. The CPAP trial was a multicenter, randomized, 3-parallel arm, sham-controlled 12 week clinical trial to assess the use of a nocturnal CPAP device on airways reactivity to methacholine. The lack of a treatment effect of CPAP on clinical or HRCT measures provided an opportunity for the current analysis...

Rhinovirus, a major causative agent of the common cold, is associated with exacerbation of asthma and chronic obstructive pulmonary disease. Currently, there is no antiviral treatment or vaccine for human rhinovirus (HRV). Gemcitabine (2',2'-difluorodeoxycytidine, dFdC) is a deoxycytidine analog with antiviral activity against rhinovirus, as well as enterovirus 71, in vitro. However, the antiviral effects of gemcitabine in vivo have not been investigated. In the current study, we assessed whether gemcitabine mediated antiviral effects in the murine HRV infection model...

BACKGROUND: While the importance of the Th2 cytokine IL-13 as a central mediator of airway hyperreactivity (AHR) has been described in allergic protein-induced asthma, this has never been investigated in chemical-induced asthma. OBJECTIVE: We examined the importance of IL-13 in a mouse model of chemical-induced AHR, using toluene-2,4-diisocyanate (TDI). METHODS: In a first set-up, wild type (WT) and IL-13 knockout (KO) C57Bl/6 mice were dermally treated on days 1 and 8 with 1% TDI or vehicle (acetone/olive oil) on both ears...

OBJECTIVE: Asthma severity is defined as the intensity of treatment required to achieve good control of asthma symptoms. Studies have shown that work-related asthma (WRA) can be associated with poorer asthma control and more severe symptoms than non-WRA. Associations between asthma medications and WRA status were assessed using data from the 2012-2013 Asthma Call-back Survey among ever-employed adults (≥18 years) with current asthma from 29 states. METHODS: Persons with WRA had been told by a physician that their asthma was work-related...

The xenoestrogens Bisphenol-A (BPA) and Nonylphenol (NP) are endocrine disruptors used in the plastic polymer industry to manufacture different products for human use. Previous studies have suggested a role of these compounds in the shedding of signaling molecules, such as tumor necrosis factor α (TNF- α). The aim of this work was to evaluate the effect of BPA and NP on the sheddase ADAM17 and its newly discovered regulators iRhom1 and iRhom2 in the release of EGFR-ligands. We report that BPA and NP can stimulate the release of the ADAM17-substrates HB-EGF and TGF- α...
