BACKGROUND: Asthma is a chronic respiratory disease without a cure, though there exists spontaneous remission. Genome wide association(GWA) studies have pinpointed genes associated with asthma development, but did not investigate asthma remission. OBJECTIVES: We performed a GWA study to develop insights in asthma remission. METHODS: Clinical remission (ClinR) was defined by absence of asthma treatment and wheezing in the last year and asthma attacks in the last 3 years, and complete remission (ComR) similarly but additionally with normal lung function and absence of bronchial hyperresponsiveness (BHR)...

A small percentage of patients with asthma have uncontrolled symptoms and frequent exacerbations, despite treatment with inhaled corticosteroids and other agents. It has become clear that different subtypes of this severe, treatment-resistant group exist due to different mechanisms of the disease. All such patients require detailed assessment in specialist centers to characterize the disease and assess treatment adherence. Recently, monoclonal antibodies have become available, which target specific pathways that may contribute to persistent inflammation and asthma exacerbations...

The importance of understanding how interleukin-33 (IL-33) is regulated (particularly by miRs) is critical in IL-33 biology, and evidence of this in asthma pathology is limited. MicroRNA profiling of cells isolated from bronchoalveolar lavage of 14 asthmatic patients and 11 healthy controls revealed miR-200b and miR-200c were significantly reduced in asthmatic patients compared with healthy controls. The reduction was validated in two independent models of allergen-induced allergic airway inflammation and further demonstrated to be inversely correlated with asthma severity, as well as increased IL-33 production in asthmatic patients...

BACKGROUND: The utility of serum biomarkers related to inflammation and adiposity as predictors of metabolic disease prevalence and outcomes after bariatric surgery are not well-defined. METHODS: Associations between pre- and post-operative serum levels of four biomarkers (C-reactive protein (CRP), cystatin C (CC), leptin, and ghrelin) with baseline measures of adiposity and metabolic disease prevalence (asthma, diabetes, sleep apnea), and weight loss and metabolic disease remission after bariatric surgery were studied in the Longitudinal Assessment of Bariatric Surgery (LABS) cohort...

MicroRNAs are small noncoding RNAs that inhibit gene expression posttranscriptionally, implicated in virtually all biological processes. Although the effect of individual microRNAs is generally studied, the genome-wide role of multiple microRNAs is less investigated. We assessed paired genome-wide expression of microRNAs with total (cytoplasmic) and translational (polyribosome-bound) mRNA levels employing subcellular fractionation and RNA sequencing (Frac-seq) in human primary bronchoepithelium from healthy controls and severe asthmatics...

Eosinophilic granulomatosis with polyangiitis (formerly Churg-Strauss syndrome) is a rare type of anti-neutrophil cytoplasm antibody-associated vasculitis. Nevertheless, eosinophilic granulomatosis with polyangiitis stands apart because it has features of vasculitis and eosinophilic disorders that require targeted therapies somewhat different from those used for other anti-neutrophil cytoplasm antibody-associated vasculitides. Considerable advances have been made in understanding the underlying pathophysiology of eosinophilic granulomatosis with polyangiitis that have highlighted the key role of eosinophils and opened new therapeutic opportunities...

Small non-coding RNAs including microRNAs (miRNAs) have been recently recognized as important regulators of gene expression. MicroRNAs play myriads of roles in physiological processes as well as in the pathogenesis of a number of diseases by translational repression or mRNA destabilization of numerous target genes. The miR-106b-25 cluster is highly conserved in vertebrates and consists of three members including miR-106b, miR-93 and miR-25. MiR-106b and miR-93 share the same seed sequences; however, miR-25 has only a similar seed sequence resulting in different predicted target mRNAs...

PURPOSE OF REVIEW: The skin barrier is a dynamic innate immune organ. This review summarizes the current understanding of how deficiencies associated with atopic dermatitis invite other atopic disorders of the allergic march. RECENT FINDINGS: Atopic dermatitis is characterized by skin barrier defects (such as mutations in filaggrin), intrinsic proallergic T-helper cell 2 immune dysregulation, and skin microbiome alterations. These factors promote the development of food allergy and asthma...

Severe asthma is associated with significant morbidity and is a highly heterogeneous disorder. Severe asthma in adolescence has some unique elements compared with the features of severe asthma a medical provider would see in younger children or adults. A specific focus on psychological issues and adherence highlights some of the challenges in the management of asthma in adolescents. Treatment of adolescents with severe asthma now includes 3 approved biologic phenotype-directed therapies. Therapies available to adults may be beneficial to adolescents with severe asthma...

Since the successful molecular cloning in 1998 of GM3 synthase (GM3S, ST3GAL5), the enzyme responsible for initiating biosynthesis of all complex gangliosides, the efforts of our research group have been focused on clarifying the physiological and pathological implications of gangliosides, particularly GM3. We have identified isoforms of GM3S proteins having distinctive lengths of N-terminal cytoplasmic tails, and found that these cytoplasmic tails define subcellular localization, stability, and in vivo activity of GM3S isoforms...

Female sex/gender is an under-characterized variable in studies related to lung development and disease. Notwithstanding, many aspects of lung and sleep biology and pathobiology are impacted by female sex and female reproductive transitions. These may manifest as differential gene expression or peculiar organ development. Some conditions are more prevalent in women, such as asthma and insomnia, or in the case of LAM, are seen almost exclusively in women. In other diseases, presentation differs such as the higher frequency of exacerbations experienced by women with COPD or greater cardiac morbidity among women with sleep disordered breathing...

BACKGROUND: Recently developed asthma biological therapies have been shown to provide relief for severe asthma patients not controlled by inhaled treatment. Given the relatively high costs of biological therapies, cost-effectiveness analyses (CEAs) may be required as a prerequisite for coverage and reimbursement. OBJECTIVE: We aimed to systematically review published literature on the economic impact of biological asthma therapies and to identify key drivers that impact cost-effectiveness in order to provide recommendations for future economic evaluations...

The presence of airway inflammation in patients with chronic obstructive pulmonary disease (COPD) provides a rationale for biological agents targeting specific inflammatory pathways. This approach has been strikingly effective in patients with other chronic inflammatory diseases, such as rheumatoid arthritis, psoriasis, and asthma. However, there are important and unresolved challenges in COPD, including our incomplete understanding of heterogeneity of the lower airway inflammatory response and how these contribute to the clinical expression of disease...

Current therapies to treat asthma and other airway diseases primarily include anti-inflammatory agents and bronchodilators. Anti-inflammatory agents target trafficking and resident immunocytes and structural cells, while bronchodilators act to prevent or reverse shortening of airway smooth muscle (ASM), the pivotal tissue regulating bronchomotor tone. Advances in our understanding of the biology of G protein-coupled receptors (GPCRs) and biased agonism offers unique opportunities to modulate GPCR function that include the use of pepducins and allosteric modulators...

Upper and lower respiratory symptoms and asthma are adverse health effects associated with moisture-damaged buildings. Quantitative measures to detect adverse health effects related to exposure to dampness and mold are needed. Here, we investigate differences in gene expression between occupants of moisture-damaged and reference buildings. Moisture-damaged (N=11) and control (N=5) buildings were evaluated for dampness and mold by trained inspectors. The transcriptomics cohort consisted of nasal brushings and peripheral blood mononuclear cells (PBMCs) from 86 teachers, with/without self-perceived respiratory symptoms...

Platelet activating factor(PAF), an endogenous synthesized phospholipid transmitter, has widely biological activities. It has "signal transmission" effect in various life processes, but abnormality of concentration in vivo will promote or aggravate the diseases, such as, cerebral ischemia, myocardial injury, multi-organ failure, asthma, injury of liver and kidney, severely affecting the normal life activities of body. In recent years, with the development of medical science and technology, more and more attention has been paid to the research of platelet activating factor receptor antagonist...

INTRODUCTION: Dupilumab, a fully human anti-IL-4Rα monoclonal antibody, inhibits signaling of both interleukin (IL)-4 and IL-13, which are key drivers of type 2-mediated inflammation. Dupilumab is approved in the EU, USA, and other countries for the treatment of adults with inadequately controlled moderate-to-severe atopic dermatitis. Following positive phase 2 results in asthma, the phase 3 Liberty Asthma QUEST trial was initiated to provide further evidence for dupilumab efficacy and safety in patients with uncontrolled, moderate-to-severe asthma...

This in vitro study evaluated, for the first time, the safety and the biological activity of a novel urea-crosslinked hyaluronic acid component and sodium ascorbyl phosphate (HA-CL - SAP), singularly and/or in combination, intended for the treatment of inflammatory lung diseases. The aim was to understand if the combination HA-CL - SAP had an enhanced activity with respect to the combination native hyaluronic acid (HA) - SAP and the single SAP, HA and HA-CL components. Sample solutions displayed pH, osmolality and viscosity values suitable for lung delivery, and showed to be not toxic on epithelial Calu-3 cells at the concentration used in this study...
