Serum concentrations of creatinine and of the three low molecular weight (LMW) proteins cystatin C, factor D of the complement system and beta 2-microglobulin were measured in 135 consecutive patients, whose glomerular filtration rates (GFR) were determined by Cr-EDTA. In the total patient series, the reciprocals of S-creatinine and S-cystatin C were numerically and, in males, significantly more closely correlated to GFR than the reciprocals of S-factor D. The reciprocals of beta 2-microglobulin showed a weaker correlation to GFR than those of the other three substances. The calculated glomerular elimination rates of creatinine, cystatin C and factor D were normally distributed, in contrast to those of beta 2-microglobulin. According to data presented so far, cystatin C seems to be the LMW protein of first choice when GFR is to be estimated by measuring the plasma concentration of a LMW protein.

Serum levels of complement factor D, a low molecular weight (LMW) protein, were high and inversely correlated with glomerular filtration rate (GFR) determined in 19 patients with lupus glomerulonephritis (LGN). Factor D was significantly closer correlated with S-creatinine than were two other LMW proteins, beta 2-microglobulin and gamma-trace in 22 LGN patients. Close correlations between each of the LMW proteins and S-creatinine were found in patients with a non-inflammatory disorder, polycystic kidney disease. Slightly increased beta 2-microglobulin concentrations were found in 15 of 20 systemic lupus erythematosus (SLE) patients without renal involvement, while factor D and gamma-trace showed normal values in most of these patients. The findings imply that serum concentrations of complement factor D in SLE are mainly determined by the GFR.
