In a large cohort of patients with common forms of chronic kidney disease (CKD), researchers found that urine-to-plasma ratio of urea ([U/P]urea) was independently associated with CKD progression and kidney failure.

An association of urinary concentrating capacity with CKD progression, independently of(GFR), supports the notion that a more comprehensive assessment offunction than is typically performed in clinical practice today, might improve risk prediction.

The GFR, despite being the primary indicator of kidney function, does not fully capture the kidneys' state of health, even with the addition of albuminuria. In a large cohort of patients with common forms of CKD, researchers found that a lower [U/P]was associated with more rapid eGFR decline and development ofindependently of other major risk factors for CKD progression.

Their results were recently published in theAmerican Journal of Kidney Diseases (AJKD).

Urea distinguishes itself from many other proposed biomarkers of tubular function by its central role in kidney physiology. Moreover, it is easily measured at a low cost in most clinical laboratories using standardized assays.

Thus, [U/P]ureacould represent an accessible marker of CKD progression, not only in ADPKD, but in forms of CKD with high prevalence.
