Identifying biomarkers linked to severity in adults with RSV infections

Identification and Clinical Validation of Biomarkers Associated With Clinical Severity in Adults Infected With Respiratory Syncytial Virus

Assistance Publique - Hôpitaux de Paris · NCT06197152

This study is trying to find specific markers in the body that can help doctors understand how severe Respiratory Syncytial Virus (RSV) infections are in adults who are hospitalized.

What this trial studies

This observational study aims to identify and clinically validate biomarkers associated with the severity of Respiratory Syncytial Virus (RSV) infections in adults. It focuses on patients over 18 years old who are hospitalized with clinical signs of lower respiratory tract infection and have tested positive for RSV via RT-PCR. The study involves collecting nasopharyngeal swabs and biological samples to analyze the relationship between viral load, viral subtypes, and clinical outcomes. The findings could enhance understanding of RSV severity and inform treatment strategies.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old who are hospitalized with confirmed RSV infections and exhibit clinical signs of lower respiratory tract infection.

Not a fit: Patients with co-infections from other respiratory viruses or those under guardianship may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved risk stratification and management of RSV infections in adults, potentially reducing morbidity and mortality.

How similar studies have performed: While there is limited data on the specific biomarkers for RSV severity, similar studies have shown promise in identifying viral load correlations with clinical outcomes in respiratory infections.
