AI Article Synopsis

  • SARS-CoV-2, the virus responsible for COVID-19, causes serious health issues primarily affecting the lungs and the cardiovascular system, leading to complications like acute respiratory distress syndrome (ARDS).
  • Many people infected with the virus experience mild symptoms, but severe cases can result in serious respiratory complications and a higher risk of death.
  • This review aims to explore how SARS-CoV-2 affects different parts of the respiratory system and the long-term consequences of the infection, especially the risk of developing chronic lung fibrosis in COVID-19 survivors.

Article Abstract

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causes acute coronavirus disease-19 (COVID-19) that has emerged on a pandemic level. Coronaviruses are well-known to have a negative impact on the lungs and cardiovascular system. SARS-CoV-2 induces a cytokine storm that primarily targets the lungs, causing widespread clinical disorders, including COVID-19. Although, SARS-CoV-2 positive individuals often show no or mild upper respiratory tract symptoms, severe cases can progress to acute respiratory distress syndrome (ARDS). Novel CoV-2 infection in 2019 resulted in viral pneumonia as well as other complications and extrapulmonary manifestation. ARDS is also linked to a higher risk of death. Now, it is essential to develop our perception of the long term sequelae coronavirus infection for the identification of COVID-19 survivors who are at higher risk of developing the chronic lung fibrosis. This review study was planned to provide an overview of the effects of SARS-CoV-2 infection on various parts of the respiratory system such as airways, pulmonary vascular, lung parenchymal and respiratory neuromuscular system as well as the potential mechanism of the ARDS related respiratory complications including the lung fibrosis in patients with severe COVID-19.

Acute lung injury (ALI) is a severe inflammatory condition of the respiratory system, associated with high morbidity and mortality. This study investigates the therapeutic potential of tocilizumab (TZ), an IL-6 receptor inhibitor, in mitigating lipopolysaccharide (LPS)-induced ALI by modulating the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway. An ALI model was established using LPS induction.

Cystic Fibrosis (CF) is a life-threatening hereditary disease resulting from mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene that encodes a chloride channel essential for ion transport in epithelial cells. Mutations in CFTR, notably the prevalent F508del mutation, impair chloride transport, severely affecting the respiratory system and leading to recurrent infections. Recent therapeutic advancements include CFTR modulators such as ETI, a combination of two correctors (Elexacaftor and Tezacaftor) and a potentiator (Ivacaftor), that can improve CFTR function in patients with the F508del mutation.

Rare constituents of the nasal microbiome contribute to the acute exacerbation of chronic rhinosinusitis.

Inflamm Res

January 2025

Department of Otolaryngology, Peking University Third Hospital, Haidian District, No. 49 Huayuan North Road, Beijing, 100191, People's Republic of China.

Background: Dysbiosis of the nasal microbiome is considered to be related to the acute exacerbation of chronic rhinosinusitis (AECRS). The microbiota in the nasal cavity of AECRS patients and its association with disease severity has rarely been studied. This study aimed to characterize nasal dysbiosis in a prospective cohort of patients with AECRS.

Rationale: Preterm infants diagnosed with bronchopulmonary dysplasia (BPD) are thought to have fewer and larger alveoli than their term peers, but it is unclear to what degree this persists later in life.

Objectives: To investigate to what degree the distal airspaces are enlarged in adolescents born preterm and to evaluate the new Airspace Dimension Assessment (AiDA) method in investigating this group.

Methods: We investigated 41 adolescents between 15 and 17 years of age, of whom 25 were born very preterm (a gestational age <31 weeks, with a mean of 26 weeks) and 16 were term-born controls.

Introduction: Bronchiectasis exacerbation (BE) is associated with unfavorable sequelae in other organs such as the cardiovascular system; data regarding its impact on adverse term renal outcomes, however, is lacking.

Methods: A territory-wide retrospective cohort study was conducted in Hong Kong between 1/1/1993 and 31/12/2017. All patients with bronchiectasis followed in the public healthcare system in 2017 were classified as "Exacerbators" or "Non-Exacerbators," and their adverse renal outcomes (renal progression [decrease in eGFR by 30 mL/min lasted for more than 12 months during follow up], acute kidney injury [AKI], and annual rate of eGFR decline) in the ensuing 7 years were compared.
