Purpose Of Review: Asthma exacerbations are associated with substantial symptom burden and healthcare costs. Viral infections are the most common identified cause of asthma exacerbations. The epidemiology of viral respiratory infections has undergone a significant evolution during the COVID-19 pandemic. The relationship between viruses and asthmatic hosts has long been recognized but it is still incompletely understood. The use of newly approved asthma biologics has helped us understand this interaction better.
Recent Findings: We review recent updates on the interaction between asthma and respiratory viruses, and we address how biologics and immunotherapies could affect this relationship by altering the respiratory mucosa cytokine milieu. By exploring the evolving epidemiological landscape of viral infections during the different phases of the COVID-19 pandemic, we emphasize the early post-pandemic stage, where a resurgence of pre-pandemic viruses with atypical seasonality patterns occurred. Finally, we discuss the newly developed RSV and SARS-CoV-2 vaccines and how they reduce respiratory infections.
Summary: Characterizing how respiratory viruses interact with asthmatic hosts will allow us to identify tailored therapies to reduce the burden of asthma exacerbations. New vaccination strategies are likely to shape the future viral asthma exacerbation landscape.

Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), is increasingly recognized as a condition affecting not only adults but also children and adolescents. While children often experience milder acute COVID-19 symptoms compared to adults, some develop persistent physical, psychological, and neurological symptoms lasting for weeks or months after initial infection. The most commonly reported symptoms include debilitating fatigue, respiratory issues, headaches, muscle pain, gastrointestinal disturbances, and cognitive difficulties, which significantly impact daily activities, schooling, and social interactions.

Asthmatic children who tested positive for COVID-19 experienced changes in lung function and persistent symptoms following SARS-CoV-2 infection, even for several months after diagnosis, and with the same features as in an acute phase. This study aimed to analyze a pediatric age group (between 0 and 17 years old) diagnosed with asthma, and SARS-CoV-2 infection attending regular monitoring visits in a Pediatric Department of a Regional Tertiary Hospital (Filantropia Clinical Municipal Hospital Craiova, Romania) during the COVID-19 pandemic and post-pandemic time interval (i.e.

Uncontrolled, severe asthma remains a significant clinical challenge, affecting a small proportion of asthma patients worldwide. Despite advancements in treatment options, a subset of patients continues to experience frequent exacerbations, uncontrolled symptoms, and impaired quality of life. The advent of biological therapies has revolutionized the management of severe asthma, offering targeted treatments that address specific inflammatory pathways.

Chronic obstructive pulmonary disease (COPD) exacerbations are major contributors to morbidity and mortality, highlighting the need to better understand their molecular mechanisms to improve prevention, diagnosis, and treatment. This study investigated differential gene expression profiles and key biological processes in COPD exacerbations categorized based on sputum microbiome profiling. An observational study was performed on a cohort of 16 COPD patients, who provided blood and sputum samples during exacerbations, along with five stable-state samples as controls.

Increasing epidemiological evidence has proved that early-life exposure to inorganic arsenic (As) elevates the risks of childhood asthma. The present research aimed to explore susceptibility of respiratory As exposure to allergic asthma in a mouse model. BALB/c mice on postnatal day (PND) 28 were exposed to ddHO or NaAsO aerosol for 4 hours daily over 5 consecutive weeks via respiratory tract.
