  • Title: Recurrence of dense deposits in transplanted kidney: II. Serum complement and nephritic factor profiles.
    Author: Leibowitch J, Halbwachs L, Wattel S, Gaillard MH, Droz D.
    Journal: Kidney Int; 1979 Apr; 15(4):396-403. PubMed ID: 390216.
    Abstract:
    Dense deposit disease of the kidney is a rare form of chronic glomerulonephritis frequently associated with serum complement abnormalities (low C3 levels) and a circulating C3 convertase activator of the alternative pathway, the C3 nephritic factor (NF). Eleven patients with end-stage dense deposit disease underwent kidney transplantation. Of the 11, 7 had pretransplant low C3 and NF. In the posttransplant period, persisting low C3 levels were associated with persisting NF, although not quantitatively so. The original glomerular lesion recurred in the graft within 6 months in 9 of 11. Of these 9, 2 had no complement abnormalities either prior to or after transplantation. Pretransplant complement abnormalities were rapidly corrected in 4 of 7 patients whether or not recurrence of the original lesion occurred. Thus, serum complement profiles before and after transplantation are neither predictive nor indicative of recurrence.
