The Impact of Cidofovir on the Renal Function of Pediatric Solid Organ Transplant Recipients
Methods: Summary statistics were presented for demographics and outcomes, Wilcoxon signed-rank tests to compare changes in renal function and Wilcoxon rank-sum tests to test association with potential confounding factors.
Results: We included 25 patients (mean age 4.2years; SD 4.6): liver-small bowel (15), small bowel (4), liver (3) and kidney (3) transplant recipients. Viral infections: adenovirus (20), BKv (2), HHV6 (1), and EBV (1). 24% of patients while on cidofovir compared with 4% at baseline (p=0.03) were on renal replacement therapy (RRT). For patients not on RRT, there was no difference: 1) in the median creatinine clearance between baseline and one month after (p=0.32) or end of cidofovir treatment (p=0.23); 2) in the creatinine from baseline to end of cidofovir therapy (p=0.2); there was marginal decrease in the median creatinine from baseline to one month post-cidofovir treatment (p=0.06). Less patients had proteinuria (72.2% vs. 27.8%;p=0.02) and hematuria (22.2% vs. 0%) at the end than at the beginning of cidofovir treatment. No evidences of associations were found between changes in creatinine clearance (by univariate analysis) with: exposure to vancomycin (p=0.44), amikacin (p=0.13), dopamine (p=0.66), epinephrine (p=0.99), norepinephrine (p=0.48), intravenous contrast (p=0.41) and surgery (p=0.59).
Conclusion: Cidofovir was mainly used to treat adenovirus infections. In our study, cidofovir did not have nephrotoxic effects during the treatment and 1 month after treatment in pediatric transplant recipients, although they required RRT while on cidofovir because of fluid overload.
