Predicting HSV-1 Reactivation in Critically Ill Patients Using Bronchoscopy

Performance of a Bronchoscopic Score for Prediction of Tracheobronchial Herpes Simplex Virus Type 1 (HSV-1) Reactivation

Observational University Hospital Muenster · NCT05331417

This study is testing if a special scoring system used during a lung exam can help predict when critically ill patients might have a reactivation of the Herpes Simplex Virus Type 1.

What this trial studies

This observational study investigates the ability to predict reactivation of Herpes Simplex Virus Type 1 (HSV-1) in critically ill patients through a standardized bronchoscopic score assessing tracheobronchial inflammation. The score evaluates mucosal redness, swelling, and vulnerability, with values ranging from 0 to 6 assigned by an experienced ICU physician. The presence of HSV-1 reactivation is confirmed using quantitative PCR analysis of bronchoalveolar lavage fluid, alongside secondary analyses of immunocompetence markers. The study aims to enhance understanding of HSV-1 reactivation in the context of tracheobronchitis and its implications for patient care.

Who should consider this trial

Good fit: Ideal candidates are critically ill adult patients aged 18 years or older who require bronchoscopy during their ICU stay.

Not a fit: Patients with solid organ transplants, current COVID-19 infection, or severe immunodeficiency may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prediction and management of HSV-1 reactivation in critically ill patients, potentially reducing ICU stay and mechanical ventilation duration.

How similar studies have performed: While the approach of using bronchoscopic scoring for predicting viral reactivation is innovative, similar studies have not been widely reported, indicating this may be a novel investigation.
