Correlation between urinary excretion of CAP, clinical parameters, and plasma levels of CAPa

1/SCrUP/UCrU-iC3b/UCrU-Bb/UCrU-MAC/UCrP-iC3bP-BbP-MAC
aThis analysis was performed in the proteinuric patients excluding MCNS (n = 81). Correlation coefficients (rs) are expressed in figures. Urinary excretion levels of iC3b, Bb, or MAC were significantly correlated with each other. There was no significant correlation between plasma level and urinary excretion of CAP. Urinary CAP was significantly correlated with urinary protein excretion rate. Urinary iC3b and Bb was inversely correlated with reversed serum creatinine (1/SCr), whereas urinary excretion of U-MAC was not correlated with renal function. However, when MN was excluded, urinary MAC excretion was significantly correlated with 1/SCr. Abbreviations as in Tables 1 and 2.
bP < 0.001.
cP < 0.01.
dMN was excluded.
