Study summary

Early research suggests that inflammation plays a key role in the development of SARS CoV-2 infection. The immune response to respiratory infection is characterized by an influx of neutrophils to the lungs. This study ought to investigate the association of simple biomarkers such as NLR and PLR with the clinical outcome in SARS CoV-2 infection patients.

Read the detailed description

Early research suggests that inflammation plays a key role in the development of SARS CoV-2 infection. The immune response to respiratory infection is characterized by an influx of neutrophils to the lungs. Moreover, previous studies have demonstrated that a sustained release of anti-inflammatory cytokines may lead to high levels of circulating neutrophils and lymphocytes' apoptosis with subsequent lymphopenia and immune response imbalance. Therefore, circulating biomarkers that represent inflammation and immune status could serve as potential predictors for the prognosis of SARS CoV-2 patients. The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are cheap and simply calculated biomarkers which have been identified as markers of systemic inflammation, severity of the disease and prognosis in several patient populations.

This study ought to investigate the association of simple biomarkers such as NLR and PLR with the clinical outcome in SARS CoV-2 infection patients.

Study population

Consecutive patients with SARS CoV-2 infection who were treated by the Department of Respiratory Medicine in the UHL will be done. The subjects will be followed from admission to the hospital and up until discharge, transfer to the ICU or death

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 2, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
