Résumé
Background: BK virus associated nephropathy occurs in 1-10% of
kidney transplant recipients and may be a cause of graft loss. This
infection is difficult to manage because of the absence of specific
therapy. Cidofovir, a DNA polymerase inhibitor approved for the
treatment of CMV retinitis, has shown in vitro activity against BK
virus and some clinical efficacy when used at low-dose in uncontrolled
series.
Objective: To assess the efficacy of low-dose Cidofovir in the treatment
of BK virus associated nephropathy.
Method: Two adult kidney transplant recipients with biopsy-proven
BK nephropathy and persistent high viremia (>10,000 copies/ml)
despite 3-month reduction of immunosuppressive therapy were
treated by Cidofovir 0.5 mg/kg fortnightly for a total of 16 weeks
(8 doses). Clinical response was assessed by following BK viremia.
Results: No decrease in BK viremia was observed at any point during
cidofovir therapy (see figure). Creatinine clearance remained
stable during therapy and no side-effects of Cidofovir were observed.
Conclusions: Low-dose Cidofovir therapy was not associated with
a clearance or with a significant decrease of BK viremia. This pilot
study does not confirm previous reports suggesting clinical efficacy
of Cidofovir for BK virus associated nephropathy.
