AI Article Synopsis
- Prior history of asthma significantly increases the risk of medically-attended influenza in children, with a two-fold increase observed in affected individuals.
- Obesity alone was not generally associated with influenza in the overall population; however, there was a notable trend indicating that asthmatic children with obesity were more likely to have influenza.
- These findings suggest the need for targeted vaccinations and public health strategies focusing on asthmatic children, especially regarding obesity's potential influence on influenza risk.
Article Abstract
Background: Despite long-standing recommendations for influenza vaccine in patients with asthma, whether asthma is a risk factor for medically-attended influenza is unclear. Obesity has more recently been found to be a risk factor for severe influenza in adults. Its role in children is less certain.
Materials And Methods: We conducted a 1:1 matched case-control study of all 185 children 2 to 18 years old with PCR-confirmed influenza at our institution from 2010 to 2013.
Results: Having a prior history of asthma was 2 times more common (95% CI, 1.24-3.23) among the influenza cases than the controls. Obesity was not associated with influenza overall (OR 0.94, 95% CI 0.49-1.83). However, among patients with asthma, influenza cases were 4.4 times more likely to be obese compared with subjects without influenza (95% CI, 0.93-20.58).
Conclusion: In our population, a prior diagnosis of asthma was associated with a two-fold increased risk of medically-attended influenza. In addition, among patients with asthma there was a trend toward obesity increasing the risk of influenza.

Multiomics dissection of human RAG deficiency reveals distinctive patterns of immune dysregulation but a common inflammatory signature.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

Introduction: In response to the SARS-CoV-2 pandemic in March 2020 and required adherence to infection control measures and patient and staff safety, an integrated respiratory team (IRT) developed guideline-based templates to support the team in teleconsultation reviews of their patients. Patients had been diagnosed with sleep disordered breathing, chronic obstructive pulmonary disease, asthma, interstitial lung disease or had oxygen assessment needs.
Methods: Nine IRT members collaboratively developed content for the templates to assist in clinical reviews.
CCL4 Affects Eosinophil Survival via the Shedding of the MUC1 N-Terminal Domain in Airway Inflammation.

Eosinophilic chronic rhinosinusitis (ECRS), a CRS with nasal polyps (CRSwNP), is characterized by eosinophilic infiltration with type 2 inflammation and is highly associated with bronchial asthma. Intractable ECRS with poorly controlled asthma is recognized as a difficult-to-treat eosinophilic airway inflammation. Although eosinophils are activated and coincubation with airway epithelial cells prolongs their survival, the interaction mechanism between eosinophils and epithelial cells is unclear.

Context: An inhaled corticosteroid (ICS) in combination with a long-acting β2-agonist (LABA) is a common treatment approach for asthma patients not controlled on ICS alone, but a significant proportion of patients remain uncontrolled on this combination and treatment adherence can also be a challenge. One of the options for adults whose asthma is uncontrolled in an ICS/LABA is the addition of a long-acting muscarinic receptor antagonist (LAMA), an approach commonly referred to as 'triple therapy'. The use of medium-strength ICS/LABA/LAMA is established in treating chronic obstructive pulmonary disease but is less well-established in asthma.
