REVIEW
Peter Le Souëf
Over the past year, studies into virus-induced wheeze in children have shifted towards investigations that examine the mechanisms by which respiratory viruses cause wheeze and an increase in studies examining the effects of novel interventions to reduce wheezing exacerbations. Studies on rhinovirus species (RV)-C infection have found that this is associated with a decrease in expression of CDHR3, the cellular receptor specific for this virus, and a decrease in interferon-β expression, both of which are likely to favour RV-C infection...

Background: Eosinophilic granulomatosis with polyangiitis (EGPA) is an antineutrophil cytoplasmic antibody- (ANCA-) associated small vessel vasculitis with multisystem involvement. It is characterized with asthma, eosinophilia, and renal and peripheral nervous system involvement. However, EGPA presenting with bullous skin eruption is an uncommon dermatological manifestation. We report a rare case of EGPA overlapped with mixed essential cryoglobulinemia presenting with a bullous skin eruption...

We describe a case of near-fatal asthma, treated successfully by initiation of extracorporeal membrane oxygenation (ECMO). A 29-year-old woman, known asthmatic on steroid inhalers, inhaled/nebulised bronchodilators, long-term oral prednisolone, theophylline and montelukast, presented with acute shortness of breath. She deteriorated following initial treatment with nebulised bronchodilators and magnesium sulfate requiring intubation and mechanical ventilation. Severe bronchospasm ensued following mechanical ventilation and peak airway pressures remained at 55 cm H2 O with intrinsic positive end expiratory pressure(PEEP) of 14 cm H2 O...

OBJECTIVE: Whether itraconazole monotherapy is effective in the acute stage of allergic bronchopulmonary aspergillosis (ABPA) remains unknown. The goal of this study was to compare the efficacy and safety of itraconazole and prednisolone monotherapy in ABPA. METHODS: Treatment-naive subjects with ABPA complicating asthma (January 2012 to December 2013) were randomized to receive either oral itraconazole or prednisolone for 4 months. The study was not blinded. The primary outcomes were proportion of subjects exhibiting a composite response after 6 weeks, percent decline in IgE after treatment, and numbers of subjects experiencing exacerbation...

BACKGROUND: Subsets of patients with severe asthma remain symptomatic despite prolonged, high-dose glucocorticoid therapy. We hypothesized that the clinical glucocorticoid sensitivity of these asthmatics is reflected in differences in peripheral blood dendritic cell subsets. OBJECTIVE: To compare peripheral blood leucocyte populations using flow cytometry at baseline and after 2 weeks of systemic glucocorticoid (steroid) treatment to identify immunological differences between steroid-sensitive (SS) and steroid-resistant (SR) asthmatics...

AIMS: There are no specific criteria for a step-down or withdrawal dose of omalizumab (OMA). Our purpose was to evaluate the viability of a protocol for OMAlizumab DOse REduction (the OMADORE study) in severe allergic asthma (SAA). METHODS: The study population included 35 SAA patients treated during a minimum period of 1 year with oral corticosteroids (OC) equivalent to a mean daily dose of 4 mg of methyl-prednisolone. To qualify for the protocol, the patients had to have received treatment with OMA for at least one and a half years, OC dose had to have reached the lowest tolerated dose and spirometry had to be greater than or equal to that at entry...

OBJECTIVES: We studied oral glucocorticoids and osteonecrosis, a rare but serious bone disease, in individuals with various chronic inflammatory diseases. We hypothesised that we would find stronger associations in adults versus children and in people with autoimmune diseases. DESIGN: Retrospective cohort study. SETTING: Population-representative data (1994-2013) from general practices in the UK. PARTICIPANTS: Children and adults diagnosed with asthma; inflammatory bowel disease; juvenile, psoriatic or rheumatoid arthritis; psoriasis; or systemic lupus...

Biomarkers that predict responses to oral corticosteroids (OCS) facilitate patient selection for asthma treatment. We hypothesised that asthma patients would respond differently to OCS therapy, with biomarkers and inflammometry predicting response.Adults with stable asthma underwent a randomised controlled cross-over trial of 50 mg prednisolone daily for 10 days (n=55). A six-gene expression biomarker signature ( CLC , CPA3 , DNASE1L3 , IL1B , ALPL and CXCR2 ) in induced sputum, and eosinophils in blood and sputum were assessed and predictors of response were investigated (changes in forced expiratory volume in 1 s (ΔFEV1 ), six-item Asthma Control Questionnaire score (ΔACQ6) or exhaled nitric oxide fraction (Δ F eNO ))...

BACKGROUND: Previous findings show that corticosteroid treatment during the first acute wheezing episode may reduce recurrent wheezing in children with high rhinovirus genome load at 12-month follow-up. Longer-term effects have not been investigated prospectively. METHODS: After PCR confirmation of rhinovirus from nasopharyngeal aspirate, 79 children with the first acute wheezing episode were randomized to receive orally prednisolone or placebo for 3 days. The initiation of asthma control medication before the age of 5 years was confirmed from medical record and/or from parental interview...

BACKGROUND: Patients with severe asthma appear relatively corticosteroid resistant. Corticosteroid responsiveness is closely related to the degree of eosinophilic airway inflammation. The extent to which eosinophilic airway inflammation in severe asthma responds to treatment with systemic corticosteroids is not clear. OBJECTIVE: To relate the physiological and inflammatory response to systemic corticosteroids in asthma to disease severity and the baseline extent of eosinophilic inflammation...

Respiratory diseases account for about 25% of all pediatric consultations, and 10% of these are for asthma. The other main pediatric respiratory diseases, in terms of incidence, are bronchiolitis, acute bronchitis and respiratory infections. Oral corticosteroids, in particular prednisolone, are often used to treat acute respiratory diseases given their anti-inflammatory effects. However, the efficacy of treatment with oral corticosteroids differs among the various types of pediatric respiratory diseases. Notably, also the adverse effects of corticosteroid treatment can differ depending on dosage, duration of treatment and type of corticosteroid administered - a case in point being growth retardation in long-course treatment...

Omalizumab has been shown to be an effective add-on therapy for patients with uncontrolled severe persistent allergic asthma. There has been a steady accumulation of evidence on the long-term effectiveness of omalizumab; however, data on real-life outcomes beyond one year of treatment is limited. In this study, we report on long-term outcomes of omalizumab treatment. We collected data from our severe asthma registry on hospitalisations, exacerbations, corticosteroid sparing, asthma control, lung function, biomarkers and side effects, to determine if the benefit was sustained and treatment was safe on the long term...

Omalizumab is marketed for chronic severe asthma patients who are allergic to perennial allergens. Our purpose was to investigate whether omalizumab is also effective in persistent severe asthma due to seasonal allergens. Thirty patients with oral corticosteroid-dependent asthma were treated with Omalizumab according to the dosing table. For each patient with asthma due to seasonal allergens, we recruited the next two consecutive patients with asthma due to perennial allergens. The dose of oral methyl prednisolone was tapered at a rate of 2 mg every two weeks after the start of treatment with omalizumab depending on tolerance...
