BACKGROUND: Severe asthma in children is a heterogeneous disorder associated with variable responses to corticosteroid treatment. Criterion standards for corticosteroid responsiveness assessment in children are lacking. OBJECTIVE: This study sought to characterize systemic corticosteroid responses in children with severe asthma after treatment with intramuscular triamcinolone and to identify phenotypic and molecular predictors of an intramuscular triamcinolone response...

BACKGROUND: There is no agreed upon definition of systemic corticosteroid response in asthmatic children. Moreover, pediatric severe therapy-resistant asthma (STRA) is heterogeneous, and thus response to steroids is unlikely to be uniform in all patients. OBJECTIVE: We sought to evaluate the utility of a multidomain approach incorporating symptoms, lung function, and inflammation to determine steroid responsiveness in pediatric patients with STRA. METHODS: Eighty-two children (median age, 12 years) with STRA received a clinically indicated dose of intramuscular steroid...

Eosinophilic otitis media (EOM) is a type of intractable otitis media that occurs mainly in patients with bronchial asthma (BA). In 2011, the diagnostic criteria for EOM were established. EOM is characterized by the presence of a highly viscous yellowish effusion containing eosinophils and immunoglobulin E (IgE), eosinophil chemoattractants, such as eosinophil cationic protein, interleukin-5, and eotaxin. Local sensitization against foreign agents such as fungi or bacteria (e.g., Staphylococcus aureus) may result in local IgE production in the middle ear and may be responsible for the severity of EOM...

BACKGROUND: Although ethnicity may influence response to treatment of patients with asthma, this approach is controversial. The objective of this study was to determine if ethnicity influences the response to IM steroid use (eliminating adherence as an issue). METHODS: Children with severe therapy-resistant asthma who had previously undergone a detailed assessment (including a nurse-led hospital and home visit in which potentially modifiable factors had been identified and addressed) were admitted for further evaluation; this evaluation included assessment of steroid response...

REVIEW

BACKGROUND: Asthma is the most common chronic medical condition among children and is one of the most common causes of hospitalisation and medical visits. Poorly controlled asthma often leads to preventable exacerbations that require additional medications, hospital stays, or treatment in the emergency department.Long-acting beta2-agonists (LABA) are the preferred add-on treatment for children with asthma whose symptoms are not well controlled on inhaled corticosteroids (ICS). The US Food and Drug Administration has issued a 'black box' warning for LABA in asthma, and now recommends that they be used "for the shortest duration of time required to achieve control of asthma symptoms and discontinued, if possible, once asthma control is achieved"...

BACKGROUND: The mechanisms underlying glucocorticoid responsiveness are largely unknown. Although redox regulation of the glucocorticoid receptor (GR) has been reported, it has not been studied in asthmatic patients. OBJECTIVE: We characterized systemic cysteine oxidation and its association with inflammatory and clinical features in healthy children and children with difficult-to-treat asthma. We hypothesized that cysteine oxidation would be associated with increased markers of oxidative stress and inflammation, increased features of asthma severity, decreased clinically defined glucocorticoid responsiveness, and impaired GR function...

Inhaled and intranasal corticosteroids (ICS and INS) are among the mainstays of the treatment for asthma and allergic rhinitis, respectively, and also carry the potential to suppress the hypothalamic-pituitary-adrenal (HPA) axis. Several important factors affect the interpretability of trials investigating the impact of ICS and INS on the HPA axis. This paper reviews 106 published clinical trials, peer-reviewed articles, and New Drug Application reviews of approved ICS and INS, using MEDLINE and Drugs@FDA database...

BACKGROUND: Nonadherence to medications occurs in up to 70% of patients with asthma. The effect of improving adherence is not well quantified. We developed a mathematical model with which to assess the population-level effects of improving medication prescribing and adherence for asthma. METHODS: A mathematical model, calibrated to clinical trial data from the U.S. NHLBI-funded SOCS trial and validated using data from the NHLBI SLIC trial, was used to model the effects of increased prescribing and adherence to asthma controllers...

BACKGROUND: Both immediate, type I reactions and delayed hypersensitivity, type IV reactions to systemic corticosteroid preparations have been reported. Type I reactions are rare, with delayed hypersensitivity reactions being slightly more common. CASES: A 33-year-old woman presented repeatedly to the emergency department with asthma attacks. She developed pruritus and hives approximately 30 minutes after the administration of parenteral corticosteroids. Her respiratory status deteriorated approximately 6 hours after she received the corticosteroids...

Asthma is one of the most prevalent diseases in the world, for which the mainstay treatment has been inhaled glucocorticoids (GCs). Despite the widespread use of these drugs, approximately 30% of asthma sufferers exhibit some degree of steroid insensitivity or are refractory to inhaled GCs. One hypothesis to explain this phenomenon is interpatient variability in the clearance of these compounds. The objective of this research is to determine how metabolism of GCs by the CYP3A family of enzymes could affect their effectiveness in asthmatic patients...

There is a lack of high-quality evidence on what treatment should be used in children with properly characterised severe, therapy-resistant asthma. Data have to be largely extrapolated from trials in children with mild asthma, and adults with severe asthma. Therapeutic options can be divided into medications used in lower doses for children with less severe asthma, and those used in other paediatric diseases but not for asthma (for example, methotrexate). In the first category are high-dose inhaled corticosteroids (ICS) (≤ 2,000 μg · day(-1) fluticasone equivalent), oral prednisolone, the anti-immunoglobulin (Ig)E antibody omalizumab, high-dose long-acting β(2)-agonists, low-dose oral theophylline and intramuscular triamcinolone...

REVIEW
Andrew Bush, Louise Fleming
The acid test of phenotyping is that it leads either to a clinically useful or mechanistically important insight. Phenotypes may change over time, but the exact definition of a phenotype shift is unclear. Methods of phenotyping are either investigator driven, in which a priori prejudices are applied to the data, or (semi) objective, in which mathematical techniques or systems biology approaches are applied to the dataset. However, the composition of the dataset is driven by investigator prejudice. Phenotyping is likely most useful in severe asthma, because mild and moderate asthma responds to simple treatments, and no great subtlety is required...

The use of fillers for cosmetic purposes is becoming increasingly frequent. Although initially considered inert, these products produce adverse reactions around the injection site. We present 5 cases of women with a history of filler injections who presented a hard and persistent angioedema followed by local subcutaneous nodules. They were referred to the allergist for suspected allergy related angioedema without response to usual antihistamine treatment. The angioedema episodes initiated 27.6 months (range 1 to 48) after the fillers treatment...

The interaction between ambient air pollution and asthma medication remains unclear. The authors compared airway inflammation response to air pollution among asthmatics. Increases of 10 ppb of nitrogen dioxide (NO2) and of 10 microg/m3 of particulate matter < 10 micron in diameter (PM10) daily concentrations were associated with an increase in exhaled nitric oxide (eNO) of 0.13 ppb (95% confidence interval = 0.06, 0.19) and of 0.07 ppb (95% confidence interval = 0.02, 0.12), respectively, in models adjusted for important covariates...

The National Heart, Lung and Blood Institute guidelines for the treatment of asthma suggest that inhaled corticosteroids, with the addition of a long-acting bronchodilator, may be the most effective long-term control medication for asthma. Five inhaled corticosteroids are approved for use in the USA, including beclomethasone dipropionate, budesonide, flunisolide, triamcinolone acetonide and fluticasone propionate. Fluticasone propionate (Flixotide) and the long-acting beta2 agonist salmeterol (Serevent), are now available in the USA together in an easy to use dry powder inhaler Advair...

Responses of patients with persistent asthma to ambient air pollution may be different from those of general populations. For example, asthma medications may modify the effects of ambient air pollutants on peak expiratory flow (PEF). Few studies examined the association between air pollution and PEF in patients with persistent asthma on well-defined medication regimens using asthma clinical trial data. Airway obstruction effects of ambient air pollutants, using 14,919 person-days of daily self-measured peak expiratory flow (PEF), were assessed from 154 patients with persistent asthma during the 16 wk of active treatment in the Salmeterol Off Corticosteroids Study trial...
