Insights
High levels of Plasminogen activator inhibitor-1 (PAI-1) indicate severe coronavirus disease (COVID-19). This endothelial injury marker may predict hospitalization and poor outcomes in COVID-19 patients, suggesting its use in clinical assessment.
Area of Science:
- Cardiovascular Medicine
- Infectious Diseases
- Pathophysiology
Background:
- Endothelial dysfunction is a hallmark of severe coronavirus disease (COVID-19).
- Plasminogen activator inhibitor-1 (PAI-1) is implicated in endothelial injury and may serve as a prognostic indicator.
- Understanding PAI-1's role can inform COVID-19 patient management.
Purpose of the Study:
- To investigate the association between plasma PAI-1 levels and COVID-19 severity.
- To determine if PAI-1 can serve as a prognostic biomarker for severe COVID-19 outcomes.
Main Methods:
- Single-center retrospective chart review of 113 hospitalized COVID-19 patients.
- Plasma PAI-1 levels measured via ELISA.
- Comparison of PAI-1 levels between severe (ventilator use/death) and non-severe COVID-19 groups.
Main Results:
- A significant positive correlation was observed between age and PAI-1 levels.
- Elevated PAI-1 levels were noted in patients with hyperlipidemia.
- PAI-1 levels were significantly higher in patients requiring mechanical ventilation or who died compared to others.
Conclusions:
- High plasma PAI-1 levels are significantly associated with severe COVID-19.
- PAI-1 may function as a valuable biological marker for predicting severe COVID-19 and adverse outcomes.
Abstract:
Evidence indicates endothelial dysfunction in severe coronavirus disease (COVID-19). Plasminogen activator inhibitor-1 (PAI-1) is a marker of endothelial injury and could be a prognostic marker for COVID-19-related hospitalization and outcomes. The association between PAI-1 levels and the severity of COVID-19-related outcomes was investigated in this study. This single-center retrospective chart review included 113 hospitalized adults from 6.29.2020 to 8.1.2021 with confirmed COVID-19. Plasma PAI-1 levels were measured by ELISA. The primary endpoint was the difference in PAI-1 levels between severe and non-severe COVID-19 groups. Severe COVID-19 was defined as the need for ventilator assistance and/or death. The mean age was 60.78 (22 to 103, SD ± 16.93), and 52 were female and 63 male. There was a significant positive correlation between age and PAI-1 levels. PAI-1 levels were significantly higher in patients with hyperlipidemia. PAI-1 levels in patients requiring ventilator assistance and who died versus those who did not are significantly higher. High plasma PAI-1 levels are associated with severe COVID-19, defined as requiring ventilator use and/or death. Thus, PAI-1 may be a biological marker for severe COVID-19.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
