Abstract
Background
Data on the risk factors for chronic kidney disease in children with immunoglobulin A nephropathy (IgAN) are scarce. This study was aimed at investigating whether glomerular C4d immunostaining is a prognostic marker in pediatric IgAN.
Methods
In this retrospective cohort study, 47 patients with IgAN biopsied from 1982 to 2010 were evaluated. Immunohistochemistry for C4d was performed in all cases. For analysis, patients were grouped according to positivity or not for C4d in the mesangial area. Primary outcome was a decline in baseline estimated glomerular filtration rate (eGFR) by 50% or more.
Results
Median follow-up was 8.3 years. Median renal survival was 13.7 years and the probability of a 50% decline in eGFR was 13% over 10 years. Nine children exhibited the primary outcome and 4 developed end-stage renal disease (ESRD). Compared with C4d-negative patients (n = 10), C4d-positive patients (n = 37) presented higher baseline proteinuria (1.66 ± 0.68 vs 0.47 ± 0.19 g/day/1.73 m2, p < 0.001), a progressive decline in eGFR (−10.04 ± 19.38 vs 1.70 ± 18.51 ml/min/1.73 m2/year; p = 0.045), and more frequently achieved the primary outcome (50.0 vs 10.8%, p = 0.013), and ESRD (30.0 vs 2.7%, p = 0.026). No difference was observed in Oxford classification variables. Baseline proteinuria, endocapillary hypercellularity and mesangial C4d deposition were associated with primary outcome in univariate analysis. Proteinuria and mesangial C4d deposition at baseline independently predicted the decline in eGFR. Renal survival was significantly reduced in C4d-positive patients (8.6 vs 15.1 years in C4d-negative patients, p < 0.001).
Conclusions
In this exclusively pediatric cohort, positivity for C4d in the mesangial area was an independent predictor of renal function deterioration in IgAN.
