In healthy people, high levels of tumour necrosis factor 1 were associated with the emergence of kidney problems 10 years later.
\nA large, multi-ethnic study of healthy individuals found that high blood levels of an inflammatory marker are linked with long-term decline of kidney function. The results may shed light on biological mechanisms that spur chronic kidney disease. Research was led by Pavan Bhatraju, a fellow in pulmonary and critical care medicine at the University of Washington School of Medicine.
\nThe culprit is tumour necrosis factor receptor 1 (TNFR1), which is expressed by cells in the kidneys and elsewhere in the body. It is known to contribute to inflammation and dysfunction in endothelial cells that line blood vessels, and previous studies have linked TNFR1 with disease progression in people who have kidney disease.
\n\u201cOur findings suggest it has a role in the development of chronic kidney problems in healthy people,\u201d Bhatraju said.
\nBhatraju and colleagues analysed data from 2,548 participants in the Multi-Ethnic Study of Atherosclerosis (MESA), an ongoing medical research effort involving more than 6,000 men and women in six U.S. communities. Subjects\u2019 average age was 61 years, and they were generally free of known kidney or heart disease at the start of the study, when TNFR1 levels were measured.
\n\u201cWe looked at the association of TNFR1 levels at baseline with kidney decline 10 years later,\u201d Bhatraju said. \u201cTo minimize confounding factors, we adjusted for other known risks associated with kidney disease and other biomarkers of kidney decline. TNFR1 was still strongly associated with the clinical outcomes.\u201d
\nRates of decline over 10 years were nearly four times higher among people in the highest vs. lowest TNFR1 levels. This association was independent of previously known risk factors for kidney disease
progression, and persisted across multiple subgroups of participants.
\nThe finding, he said, poses a question: \u201cIn healthy people, could we use this biomarker to identify patients who are at higher risk for kidney problems?\u201d
