Renal deposits of complement factors as predictors of end-stage renal disease and death in patients with lupus nephritis.
Ontology highlight
ABSTRACT:
Methods: We collected demographic, clinical and pathological data from 183 adult patients with LN classes II-V diagnosed with a first native kidney biopsy. Pathological data included the localization and intensity of immunofluorescence staining of C1q and C3. We obtained dates of incident ESRD and death from the United States Renal Data System and National Death Index, respectively, and evaluated survival curves and hazard ratios for ESRD and death as a composite outcome and as separate outcomes.
Results: The presence and intensity of deposits of C1q and C3 in glomeruli, tubular walls and vascular walls differed between classes and were associated with known unfavourable prognostic factors, such as hypertension, hypoalbuminemia and hypocomplementemia. However, over a median follow-up of 7.5?years, their presence and intensity were associated with neither survival free of ESRD and death nor hazard ratios for ESRD and death.
Conclusion: Renal deposits of complement factors did not predict ESRD and death in patients with LN.

<h4>Objective</h4>Lupus nephritis (LN) increases the risks of end-stage renal disease (ESRD) and death, but these risks are difficult to estimate. Since complement factors play an essential role in the pathogenesis and are deposited in the kidneys as C1q and C3, we studied whether these deposits predict ESRD and death in patients with LN.<h4>Methods</h4>We collected demographic, clinical and pathological data from 183 adult patients with LN classes II-V diagnosed with a first native kidney biops ...[more]
