Levels of plasma Ba correlate with proteinuria and a reduced glomerular filtration rate.

<p>The levels of Ba, Bb, C4a, and sC5b-9 for individual patients were correlated with the degree of proteinuria (urine protein/creatinine ratio; Up/c) and the estimated glomerular filtration rate (eGFR). (A) None of the fragments measured in plasma were significantly correlated with the Up/c. (B) Plasma Ba was inversely correlated with the eGFR. (C) Urine Ba was significantly correlated with the Up/c. (D) None of the fragments measured in the urine were significantly correlated with the eGFR.
