Abstract | OBJECTIVES: DESIGN: Multicentre observational study of consecutive HIV-positive patients with histologically or virologically-proven PML. Group A, 26 patients treated with HAART; group B, 14 patients treated with HAART plus cidofovir 5 mg/kg intravenously per week for the first 2 weeks and alternate weeks thereafter. JC virus DNA was quantified in cerebrospinal fluid (CSF) by PCR. RESULTS: Baseline virological, immunological and clinical characteristics were homogeneous between the groups. In one case cidofovir was discontinued because of severe proteinuria. There was no significant difference in HIV RNA responses and changes in the number of CD4 cells between group A and B. After 2 months of therapy, five out of 12 (42%) patients from group A and seven out of eight (87%) from group B reached undetectable JC virus DNA in the CSF (Chi-square P = 0.04); moreover, 24% of group A and 57% of group B patients showed neurological improvement or stability (P = 0.038). One-year cumulative probability of survival was 0.67 with cidofovir and 0.31 without (log-rank test, P = 0.01). Variables independently associated with longer survival were the use of cidofovir, HAART prior to the onset of PML, a baseline JC virus DNA load in CSF < 4.7 log10 copies/ml, and a baseline Karnofsky performance status > or = 60. CONCLUSIONS: In AIDS-related PML, cidofovir added to HAART is associated with a more effective control of JCV replication, with improved neurological outcome and survival compared with HAART alone.
