Background: IL-17 expression was found to be associated with many inflammatory diseases in humans, such as rheumatoid arthritis, asthma, systemic lupus erythematosus and allograft rejection and many in vitro studies have indicated a proinflammatory function for IL-17.

Objective: Prognostic value of increased serum IL-17 in asthma patients.

Methods: Serum IL-17 (ELISA) was measured in 85 asthma patients (pts), mean age 46.99 +/- 14.1 years, 61% females, 23 mild persistent, 26 moderate persistent and 36 severe persistent asthma. Using multiple regression analysis (STATISTICA 7), increased serum IL-17 (>20 pg/ml) was tested as risk factor for severe asthma in comparison with "traditional" risk factors: smoke, NSAID intolerance, obesity, chronic rhinosinusitis, blood eosinophilia, FEV(1) at baseline < 50% predicted (low FEV(1)).

Results: Medium serum IL-17 values were 14.21 pg/ml in mild asthma, 12.22 pg/ml in moderate asthma and 24.72 pg/ml in severe asthma. IL-17 values > 20 pg/ml were encountered in 3(13%) mild asthma pts (p < 0.001 vs. severe asthma), 2(8%) moderate asthma pts. (p < 0.001 vs. severe asthma), and in 11(31%) severe asthma pts. For severe asthma multiple regression analysis revealed as independent risk factors IL-17 (p = 0.000290), NSAID intolerance (p = 0.000585) and low FEV(1) (p = 0.000059).

Conclusions: IL-17 is increased in severe asthma compared to mild/moderate forms of the disease and values above 20 pg/ml are an independent risk factor for severe asthma.

SLAMF8 Disrupts Epithelial Barrier in Chronic Rhinosinusitis with Nasal Polyps via M1 Macrophage Polarization.

Background: Recent studies show that M1 macrophages accumulate predominantly in non-eosinophilic chronic rhinosinusitis with nasal polyps (neCRSwNP). However, the precise mechanisms regulating M1 macrophages and their impact on the epithelial barrier remain unclear.

Objective: We aim to investigate the expression and regulatory role of SLAMF8, a molecule exclusively expressed in myeloid cells, in M1 macrophage polarization and its potential contribution to neCRSwNP development.

Background: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract infection, hospitalisation and death in adults.

Methods: Based on evidence regarding the impact of RSV on adult populations at risk for severe infection and the efficacy and safety of RSV vaccines, the Portuguese Society of Pulmonology, the Portuguese Association of General and Family Medicine, the Portuguese Society of Cardiology, the Portuguese Society of Infectious Diseases and Clinical Microbiology, the Portuguese Society of Endocrinology, Diabetes and Metabolism, and the Portuguese Society of Internal Medicine endorses this position paper with recommendations to prevent RSV-associated disease and its complications in adults through vaccination.

Conclusion: The RSV vaccine is recommended for people aged ≥50 years with risk factors (chronic obstructive pulmonary disease, asthma, heart failure, coronary artery disease, diabetes, chronic kidney disease, chronic liver disease, immunocompromise, frailty, dementia, and residence in a nursing home) and all persons aged ≥60 years.

Objectives: To examine the extent to which asthma symptom concordance (ASC) or discordance (ASD) is associated with sleep outcomes in children with persistent asthma. Also, to investigate whether the association between ASC and sleep outcomes varies as a function of children's level of asthma control and severity.

Methods: A retrospective data analysis of Project NAPS (Nocturnal Asthma and Performance in School), an observational study which examined asthma and sleep outcomes in children with persistent asthma.

Obesity is a risk factor for asthma morbidity, associated with less responsiveness to inhaled corticosteroids. CD4+ T-cells are central to the immunology of asthma and may contribute to the unique obese asthma phenotype. We sought to characterize the single cell CD4+ Transcriptional profile differences in obese children with asthma compared to normal weight children with asthma.
