Epstein–Barr virus (EBV) load in peripheral blood mononuclear cells (PBMC) and lack of correlation with proteinuria. (a) Copies of EBV DNA were measured by quantitative real time polymerase chain reaction in extracted DNA from PBMC of 35 controls, 28 patients in relapse and 20 patients in remission; *P < 0·05. (b) Correlation between proteinuria (g/mmol creatinine) and samples with positive EBV DNA load from 16 patients in relapse (dark grey plots) and 10 patients in remission (light grey plots) using Spearman's rank correlation test, not significant.
