Kidney biopsy revealed morphological findings of CG (Figure 1).
Kinetics of PB19 viremia from detection to 6 weeks after transplantation (A) and a magnified view of viral loads of PB19 (notice the Y axis difference) from the initiation of the second course of intravenous immunoglobulin (B). IVIg = intravenous immunoglobulin 500 mg/kg (gray dot); CDV = cidofovir 0.5 mg/kg (blue dot); dotted line = day of transplantation.
