The IL-33/ST2 signaling axis drives pathogenesis in acute SARS-CoV-2 infection.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), remains a significant threat to global public health. Immunopathological damage plays a role in driving pneumonia, acute respiratory distress syndrome (ARDS), and multiorgan failure in severe COVID-19. Therefore, dissecting the pulmonary immune response to SARS-CoV-2 infection is critical to understand disease pathogenesis and identify immune pathways targetable by therapeutic intervention.

Individualized approach to elexacaftor/tezacaftor/ivacaftor dosing in cystic fibrosis, in response to self-reported anxiety and neurocognitive adverse events: A case series.

The prevalence of mental health disorders is high among people with Cystic Fibrosis. The psychological symptoms in CF are associated with poor adherence, worse treatment outcomes, and greater health utilization/cost. Mental health and neurocognitive Adverse Events (AEs) have been reported with all available Cystic Fibrosis Transmembrane conductance Regulator (CFTR) modulators in small groups of patients.

ROCK STUDY in CF: sustained anti-inflammatory effects of lumacaftor-ivacaftor in sputum and peripheral blood samples of adult patients with cystic fibrosis-an observational study.

Background: Previous studies showed that the combination of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) corrector and potentiator, lumacaftor-ivacaftor (LUMA-IVA) provides meaningful clinical benefits in patients with cystic fibrosis who are homozygous for the Phe508del mutation. However, little is known about the effect of LUMA-IVA on Proinflammatory Cytokines (PICs).

Objectives: To investigate the impact of LUMA-IVA modulation on circulatory and airway cytokines before and after 12 months of LUMA-IVA treatment in a real-world setting.

A multicentre analysis of Clostridium difficile in persons with Cystic Fibrosis demonstrates that carriage may be transient and highly variable with respect to strain and level.

Purpose: Clostridium difficile has been reported to occur in the gastrointestinal tract of 50% of Cystic Fibrosis (CF) subjects, however, clinical C. difficile infection (CDI) is a rare occurrence in this cohort despite the presence of toxigenic and hypervirulent ribotypes. Here, we present the first longitudinal, multicentre analysis of C.

The Role of Ivacaftor in Severe Cystic Fibrosis in a Patient With the R117H Mutation.

Cystic fibrosis (CF) conductance transmembrane regulator functions as a chloride (Cl-) channel in multiple organs, including the lungs. More than 1,800 disease-associated mutations have been identified, which can be divided into six classes. In patients with CF due to class III gating mutations, ivacaftor produces significant improvement in lung function, weight, reduction in sweat chloride level, and pulmonary exacerbations by enhancing the probability of chloride channel opening (gating).
