BACKGROUND: The B2 receptor antagonist icatibant is approved for treatment of attacks of hereditary angioedema. Icatibant has been reported to decrease time-to-resolution of angiotensin-converting enzyme (ACE) inhibitor-associated angioedema in one study of European patients. METHODS: Patients with ACE inhibitor-associated angioedema (defined as swelling of lips, tongue, pharynx or face during ACE inhibitor use and no swelling in the absence of ACE inhibitor use) were enrolled at Vanderbilt University Medical Center from October 2007 through September 2015 and at Massachusetts General Hospital in 2012...

Oral immunotherapy-induced gastrointestinal and eosinophilic responses (OITIGER) is an adverse response to OIT in ∼8% of patients and is typically reversible by decreasing dosage administration. The peripheral blood eosinophil count serves as a biomarker marker for susceptibility and the medical course.

BACKGROUND: . Numbers of blood leukocyte subsets are highly dynamic in childhood and differ greatly between individuals. Inter-individual variation is only partly accounted for by genetic factors. OBJECTIVE: Determine which nongenetic factors affect the dynamics of innate leukocytes, and naive and memory lymphocyte subsets. METHODS: . We performed six-color flow cytometry and linear mixed effect modeling to define the dynamics of 62 leukocyte subsets from birth to 6 years of age in 1,182 children with one to five measurements per individual...

BACKGROUND: Filaggrin, encoded by the FLG gene, is an important component of the skin's barrier to the external environment and genetic defects in FLG strongly associate with Atopic Dermatitis (AD). However, not all AD patients have FLG mutations. OBJECTIVE: We hypothesised that these patients may possess other defects in filaggrin expression and processing, contributing to barrier disruption and AD, and therefore present novel therapeutic targets for this disease...

BACKGROUND: Pustular skin disorders are a category of difficult-to-treat and potentially life threatening conditions that involve the appearance of neutrophil rich pustules. The molecular basis of most pustular skin conditions has remained unknown. OBJECTIVE: We sought to investigate the molecular basis of three pustular skin disorders, generalized pustular psoriasis (GPP), palmoplantar pustulosis (PPP), and acute generalized exanthematous pustulosis (AGEP). METHODS: Microarray analyses were performed to profile genome-wide gene expression of skin biopsies obtained from GPP, PPP, AGEP patients and normal controls...

The work focused on development of a sensitive, quantitative assay for serum PLA2R-IgG with wide dynamic working range, as an aid to differential diagnosis of IMN and to exclude secondary Membranous Nephropathy with slight elevation of anti-PLA2R-IgG from IMN.

BACKGROUND: Fish is a frequent elicitor of severe IgE-mediated allergic reactions. Beside avoidance, there is currently no allergen-specific therapy available. Hypoallergenic variants of the major fish allergen, parvalbumin, for specific immunotherapy based on mutation of the two calcium-binding sites have been developed. OBJECTIVE: To establish a mouse model of fish allergy resembling human disease and to investigate whether mouse and rabbit IgG antibodies induced by immunization with a hypoallergenic mutant of the major carp allergen, mCyp c 1, protect against allergic symptoms in sensitized mice...

BACKGROUND: Mast cells are versatile key components of allergy and inflammation, known to respond to both innate and adaptive immunological stimuli. However the response of individual mast cells to cumulative stimuli remains poorly understood. OBJECTIVES: To dissect mast cell responses at the single-cell level and their potentiation by IL-33. METHODS: We monitored mast cell degranulation in real time by exploiting the capacity of fluorochrome-labeled avidin to stain degranulating cells...

NLRC4-inflammasome hyperactivity causes infantile-onset Macrophage Activation Syndrome and enterocolitis with extraordinary serum IL-18 elevation (NLRC4-MAS). Herein, we report a critically ill infant with severe, refractory NLRC4-MAS who showed sustained response to treatment with experimental IL-18 inhibition.

The ability of lung imaging to phenotype patients, determine prognosis, and to predict response to treatments is expanding in clinical and translational research. The purpose of this perspective is to describe current imaging modalities that may be useful clinical tools in asthma and other lung disorders and to explore some of the new developments in imaging modalities of the lung. These imaging modalities include chest radiography (CXR), computed tomography (CT), lung magnetic resonance imaging (MRI), electrical impedance tomography (EIT), bronchoscopy, and others...

We are facing a major challenge in bridging the gap between identifying subtypes of asthma, to understanding causal mechanisms, and translating this knowledge into personalized prevention and management strategies. In recent years, "big data" has been sold as a panacea for generating hypotheses and driving new frontiers of healthcare; the idea that the data must and will speak for themselves is fast becoming a new dogma. One of the dangers of ready accessibility of healthcare data and computational tools for data analysis is that the process of data mining may become uncoupled from the scientific process of clinical interpretation, understanding the provenance of the data and external validation...

BACKGROUND: We have recently observed that OXPHOS mediated ATP production is essential for mast cell function. Pyruvate dehydrogenase (PDH) is the main regulator of the Krebs cycle and is located upstream to the electron transport chain. However, the role of PDH in mast cell function has not been described. Microphthalmia transcription factor (MITF) regulates the development, number and function of mast cells. The localization of MITF to the mitochondria and its interaction with mitochondrial proteins has not been explored...

BACKGROUND: Type 2 airway inflammation plays a central role in the pathogenesis of allergen-induced asthma, but the underlying mechanisms remain poorly understood. We recently demonstrated that reduced mucociliary clearance, a characteristic feature of asthma, produces spontaneous type 2 airway inflammation in juvenile Scnn1b-transgenic (Scnn1b-Tg) mice. OBJECTIVE: To determine the role of impaired mucus clearance in the pathogenesis of allergen-induced type 2 airway inflammation and identify cellular sources of the signature cytokine IL-13...

BACKGROUND: Follicular helper T (Tfh) cells support the terminal B-cell differentiation. Human regulatory B (Breg) cells modulate cellular responses but their control of Tfh-dependent humoral immune responses is unknown. OBJECTIVE: To assess the role of Breg cells on Tfh development and function. METHODS: Human T cells were polyclonally stimulated in the presence of IL-12 and IL-21 to generate Tfh cells. They were co-cultured with B cells to induce their terminal differentiation...
