URGENT UPDATE: A groundbreaking study from Karolinska Institutet reveals a new web-based tool that could significantly enhance the early detection of chronic kidney disease (CKD). Published in Kidney International, researchers have confirmed that subtle abnormalities in kidney function, even within the normal range, can identify individuals at risk of developing CKD.
Chronic kidney disease is affecting 10-15% of adults globally and is projected to become one of the top five causes of years of life lost by 2040. Currently, many patients are diagnosed too late, often losing more than half of their kidney function before receiving treatment. This new tool aims to address this critical gap in healthcare.
Researchers at Karolinska Institutet constructed population-based distributions for estimated glomerular filtration rate (eGFR), the standard measure of kidney function. This initiative allows doctors to identify patients at risk and take early preventive measures.
“We were inspired by growth and weight charts used in pediatrics,” says Yuanhang Yang, postdoctoral researcher. “These charts intuitively help clinicians identify children at risk of obesity or undergrowth.” The team has made the eGFR distribution charts publicly available to healthcare professionals, alongside a web-based calculator to assess how a patient’s eGFR compares with norms for their age.
The study analyzed data from over 1.1 million adults in Stockholm, Sweden, covering about 80% of the population aged between 40 and 100 years old. Nearly seven million eGFR tests collected from 2006 to 2021 were utilized to create specific age and sex distributions. Notably, individuals with an eGFR below the 25th percentile face a significantly higher risk of developing kidney failure that necessitates dialysis or transplantation.
The research highlights a concerning trend in healthcare awareness. Among patients with an eGFR above 60 ml/min/1.73 m², but below the 25th percentile, only one-fourth had undergone additional testing for urinary albumin—critical for early kidney damage detection.
“For instance, a 55-year-old woman with an eGFR of 80 might seem normal to most clinicians,” explains Juan Jesús Carrero, professor at the Department of Medical Epidemiology and Biostatistics. “However, our charts indicate this corresponds to the 10th percentile for her age group, indicating a three-fold higher risk of needing dialysis in the future. This signals an urgent opportunity to act sooner.”
The findings underscore not just a new method for early identification but also the potential for primary prevention of chronic kidney disease. With this tool, healthcare professionals can now take proactive steps to tackle a growing health crisis.
As awareness around kidney health expands, healthcare providers are urged to utilize this innovative tool to save lives and improve patient outcomes. The implications of this research are profound, paving the way for a future where chronic kidney disease can be spotted and treated before it escalates.
