December 2024

UZ Leuven, Department of Pediatric Pulmonology, Leuven, Vlaams-Brabant, Belgium;

RATIONALE+OBJECTIVE/ Cystic fibrosis (CF) is characterized by bronchiectasis on imaging, while functionally evolving towards obstructive impairment. Despite its assumed importance in CF, small airway remodeling and its relation to bronchiectasis, is still poorly understood. METHOD/ On high-resolution computed tomography (HRCT, 600µm, CF=21, control=6) and micro-computed tomography (µCT, 150µm, CF=3, control=1) scans of inflated explant lungs, AV% (airway/total lung volume) was calculated as marker for bronchiectasis, while airway segmentation was used for generation analysis.

Trisomy 21 (TS21), also known as Down syndrome (DS), increases pediatric mortality risk from respiratory syncytial virus (RSV) by nine-fold, yet its underlying immunological basis remains unclear. Here, we investigated RSV-induced immunological responses in TS21 airway epithelial cells (AECs), the primary site of respiratory virus entry and host defense. TS21 AECs exhibit hyperactive interferon (IFN) signaling and reduced RSV infectivity, but they also show impaired type-III IFN responses during viral infection.

New paradigms in acute viral bronchiolitis: Is it time to change our approach?

Paediatr Respir Rev

November 2024

Pediatric Pulmonology, Allergy/Immunology, and Sleep Medicine, Department of Pediatrics, Indiana University, Riley Hospital for Children, Indianapolis, IN, USA.

Viral bronchiolitis is the most common pediatric acute respiratory infection leading to hospitalization, and it causes a significant healthcare burden worldwide. Current guidelines recommend supportive management after many clinical trials on specific therapies failed to demonstrate benefits. However, several studies in the past decade have revealed that bronchiolitis may not be a homogeneous disease, but instead may constitute an umbrella comprised of different "endotypes" and "phenotypes" based on patient characteristics, etiology, pathophysiological mechanisms, and clinical presentation.
