Distinct pro-inflammatory/pro-angiogenetic signatures distinguish children with Long COVID from controls.
Pediatr Res

Clinical Immunology and Vaccinology Unit, Bambino Gesù Children's Hospital IRCCS, Rome, Italy.
Background: Recent proteomic studies have documented that Long COVID in adults is characterized by a pro-inflammatory signature with thromboinflammation. However, if similar events happen also in children with Long COVID has never been investigated.
Methods: We performed an extensive protein analysis of blood plasma from pediatric patients younger than 19 years of age Long COVID and a control group of children with acute COVID-19, MIS-C, and healthy controls resulted similar for sex distribution and age.
RAGE-mediated intestinal pro-inflammatory responses triggered by Giardia duodenalis.

Giardia duodenalis is a waterborne zoonotic protozoan that causes gastrointestinal inflammation. Giardiasis and metabolic illnesses share features such as chronic inflammation and intestinal symptoms. Receptor for advanced glycation end products (RAGE) signaling plays a role in metabolic illnesses and intestinal inflammatory responses.

The management of patients with overlapping asthma and bronchiectasis requires a tailored approach, starting with a comprehensive assessment of the patient's clinical profile, including the severity of asthma and the extent of bronchiectasis. Inhaled corticosteroids (ICS) are often recommended, but their use should be carefully monitored because of the risk of increased infection. If the asthma is well controlled and the bronchiectasis remains stable, a gradual reduction in the dose of ICS may be considered.

Vascular inflammation regulates endothelial pathophenotypes, particularly in pulmonary arterial hypertension (PAH). Dysregulated lysosomal activity and cholesterol metabolism activate pathogenic inflammation, but their relevance to PAH is unclear. Nuclear receptor coactivator 7 () deficiency in endothelium produced an oxysterol and bile acid signature through lysosomal dysregulation, promoting endothelial pathophenotypes.

The continued evolution of SARS-CoV-2 variants capable of subverting vaccine and infection-induced immunity suggests the advantage of a broadly protective vaccine against betacoronaviruses (β-CoVs). Recent studies have isolated monoclonal antibodies (mAbs) from SARS-CoV-2 recovered-vaccinated donors capable of neutralizing many variants of SARS-CoV-2 and other β-CoVs. Many of these mAbs target the conserved S2 stem region of the SARS-CoV-2 spike protein, rather than the receptor binding domain contained within S1 primarily targeted by current SARS-CoV-2 vaccines.
