Paris, France – January 28, 2026 – Scientists have unveiled a groundbreaking new scoring system that can accurately predict the severity of Covid-19 infections, possibly revolutionizing how doctors allocate resources and prioritize care. The “Corimuno-Score,” developed by researchers at the National Institute of Health and Medical Research (inserm) and Paris Cité university, offers a more reliable assessment of risk than existing methods.
understanding the Ongoing Threat of Covid-19
Six years into the Coronavirus pandemic, the virus continues to pose a important global health challenge. While treatments have improved, predicting which patients will develop severe illness remains a critical task. The Sars-Cov-2 virus presents a spectrum of disease, ranging from asymptomatic infection to fatal complications, making targeted intervention tough.
The Growth of the Corimuno-Score
Researchers meticulously analyzed data from 196 hospitalized patients suffering from moderate to severe Covid-19 pneumonia, tracking their condition over three months. Blood samples were collected within 48 hours of hospitalization, with 41 immune mediators and markers of organ damage examined. The goal was to pinpoint specific biological indicators correlated with mortality.
key Markers Identified
The study revealed three crucial markers that strongly predict the risk of death: Kidney Injury Molecule-1 (KIM-1), Lipocalin-2 (LCN2), both indicative of kidney dysfunction, and Interleukin-10, an anti-inflammatory marker. The combination of these biomarkers, alongside patient age, enables a precise risk assessment.
According to Inserm,the Corimuno-Score is capable of identifying individuals at a two to three times higher risk of fatal complications.The predictive power of this new system reportedly surpasses many current laboratory tests and clinical assessments.

How can kidney biomarkers predict patient outcomes up to three months after recovering from COVID-19?
Kidney-Based Biomarkers Offer Accurate Three-Month COVID-19 Prognosis
As we move further into the post-pandemic era, understanding the long-term effects of COVID-19 remains a critical area of research. While initial focus centered on respiratory symptoms, the impact on othre organ systems, especially the kidneys, is becoming increasingly clear. Recent advancements demonstrate that kidney biomarkers can provide surprisingly accurate predictions of a patient’s health trajectory up to three months after initial COVID-19 infection. This is a significant step forward in post-COVID care and long COVID management.
The Kidney’s Role in COVID-19
It’s well-established that COVID-19 can directly and indirectly affect renal function. The virus gains entry into cells via the ACE2 receptor,which is highly expressed in the kidneys. This direct invasion can cause acute kidney injury (AKI), even in individuals without pre-existing kidney disease.
Beyond direct viral impact, COVID-19 triggers systemic inflammation and can lead to:
* Acute Tubular Necrosis: damage to the kidney’s filtering units.
* Glomerulonephritis: Inflammation of the kidney’s filtering units.
* Thrombotic Events: Blood clots that can impair kidney blood flow.
* Rhabdomyolysis: Breakdown of muscle tissue releasing harmful substances to the kidneys.
These factors contribute to a spectrum of renal complications observed in COVID-19 patients.
Identifying Predictive Biomarkers
traditionally,assessing kidney function relied on measuring serum creatinine and estimating glomerular filtration rate (eGFR). While useful, these measures often lag behind actual kidney damage. Newer research focuses on identifying more sensitive biomarkers that can detect early signs of kidney dysfunction and predict long-term outcomes. Key biomarkers showing promise include:
* Neutrophil Gelatinase-Associated Lipocalin (NGAL): Elevated levels indicate kidney tubular damage. Studies show NGAL levels correlate with the severity of COVID-19 and the risk of developing chronic kidney disease.
* Kidney injury Molecule-1 (KIM-1): Another marker of tubular injury, KIM-1 appears earlier than creatinine and can definitely help identify patients at risk of prolonged renal impairment.
* Trefoil Factor 3 (TFF3): Emerging research suggests TFF3 is a sensitive indicator of acute kidney injury and may predict recovery potential.
* Urine Albumin-to-Creatinine Ratio (UACR): A measure of protein in the urine, UACR can detect early kidney damage and is a strong predictor of cardiovascular risk in post-COVID patients.
* Renal specific metabolites: Utilizing metabolomics, researchers are identifying specific metabolites in urine and blood that correlate with COVID-19 induced kidney damage and long-term prognosis.
How Biomarkers Predict Three-Month Outcomes
Several studies have demonstrated the predictive power of these biomarkers. A study published in The Journal of the American Society of Nephrology (2025) followed COVID-19 patients for three months, regularly monitoring NGAL, KIM-1, and UACR levels. The results showed:
- Patients with persistently elevated biomarker levels at discharge were significantly more likely to experience persistent renal dysfunction at three months.
- Higher initial biomarker levels correlated with an increased risk of developing chronic kidney disease (CKD).
- Biomarker profiles could accurately stratify patients into low, medium, and high-risk groups for adverse kidney outcomes.
This ability to accurately assess risk allows for targeted interventions and personalized post-COVID follow-up.Understanding the difference between renal and kidney is critically important – renal refers to relating to the kidney, while kidney is the organ itself. Biomarkers assess the function of the kidney.
Clinical Implications & Benefits
The use of kidney-based biomarkers offers several key benefits:
* Early Detection: Identifies kidney damage before significant functional decline occurs.
* Risk Stratification: Allows clinicians to prioritize resources and focus on high-risk patients.
* Personalized Treatment: Enables tailored interventions to prevent or slow the progression of kidney disease.
* Improved Prognosis: Provides patients and clinicians with a clearer understanding of long-term health expectations.
* Enhanced Post-COVID Care: Facilitates more effective monitoring and
