Citrullinated histone H3, a marker of extracellular trap formation, is increased in blood of stable asthma patients
ConclusionsAsthma is characterized by increased circulating H3cit likely related to the enhanced lung ETs formation. Inhibition of ETs might be a therapeutic option in selected asthma phenotypes, such as neutrophilic asthma.

Rethinking Respiratory Function Test Lab in the Era of COVID-19 : considerations about the “today” and the “day after”
The 2020 Members of Proficiency Standards for Pulmonary Function Testing Committee of the American Thoracic Society recently raised concerns on pulmonary function testing (PFT) “as a potential avenue for COVID 19 transmission due to the congregation of patients with lung disease and because of the potential for coughing and droplet formation”. (1) The Committee reccommen-ded that “PFT be limited to tests that are only essential for immediate treatment decisions” an d that “personal protective equipment (PPE) for healthcare workers should be discussed with local infe-ction control team”.

Discrimination Between Atopic, Allergic, and Asthmatic Volunteers for Human Exposure Studies on Sensory Irritation.
Authors: van Kampen V, Hoffmeyer F, Monsé C, Raulf M, Brüning T, Bünger J, Sucker K Abstract Atopic, allergic, and especially asthmatic subjects might be particularly susceptible to sensory irritation induced by airborne chemicals compared to healthy individuals. Therefore, a good characterization of subjects is essential in inhalation exposure studies on sensory irritants. A total of 105 volunteers, 87% of whom reported to be non-allergic, participated in a medical examination that included skin prick test (SPT), measurements of total IgE, specific IgE (sIgE) to an ubiquitous allergen mix (sx1), and fractionate...

Racial Disparities in Allergic Outcomes Persist to Age 10 Years in Black and White Children.
CONCLUSION: Racial differences persisted in this cohort through age 10 years. Future studies should include potentially important, but rarely studied factors such as segregation and structural racism as these factors could explain the observed racial differences.

Relationship between Baseline and Post-bronchodilator Interrupter Resistance and Specific Airway Resistance in preschool children.
CONCLUSION: The poor agreement between the Rint and sRaw reference measurements demonstrates the lack of reliability of sole Rint or sRaw technique for airway obstruction diagnosis and the need to perform each technique concomitantly with BDR test. Other longitudinal and larger sample studies are needed to confirm the threshold value for a positive BDR especially for sRaw. PMID: 31945475 [PubMed - as supplied by publisher]

Sinonasal quality ‐of‐life declines in cystic fibrosis patients with pulmonary exacerbations
ConclusionCF patients with pulmonary exacerbations have worse SNOT ‐22 and CFQ‐R 14+ scores than CF patients at their baseline health. This finding suggests a temporal relationship between sinonasal and pulmonary quality of life, and that worsening of both is associated with reduced pulmonary function.

Tiotropium in Children and Adolescents With Asthma.
CONCLUSION: Once-daily tiotropium as add-on therapy is efficacious and safe in adolescents and children with moderate-to-severe asthma. These results support the expanded indication by regulatory authorities for add-on tiotropium in patients aged ≥6 years. PMID: 31805357 [PubMed - as supplied by publisher]

Tai Chi Chuan Exercise Improves Lung Function and Asthma Control through Immune Regulation in Childhood Asthma.
Conclusion: TCC exercise may improve pulmonary functions, asthma control, and QoL and prevent exacerbations in asthmatic children through immune regulation. Further research on detailed mechanisms is mandated. PMID: 31772603 [PubMed]

The relationship between frailty and Patient-Reported Outcomes in elderly patients with stable asthma
Conclusions: Frailty status assessed by the Kihon Checklist seems to be more closely associated with PROs than lung functions in stable asthmatics.

Bronchial inflammation, respiratory symptoms and lung function in patients who finished treatment for pulmonary tuberculosis: is it the beginning of a new disease?
Conclusion: This study suggests the existence of different celullar patterns once the treatment has finished and supports the basis of a treatment hypothesis.

Late Breaking Abstract - Benralizumab treatment strongly reduces blood basophils in patients with severe eosinophilic asthma
Conclusion: Benralizumab treatment strongly reduces basophils in patients with severe asthma, suggesting that the effects of Benralizumab in severe asthma might not be restricted to the depletion of eosinophils. Funding: This investigator-initiated study was funded by AstraZeneca (ESR-16-124 73).
