Intravenous cidofovir requires less frequent administration for both induction and maintenance therapy of CMV retinitis than other currently available therapies. If found to be safe and well tolerated in HIV-infected children with CMV retinitis, intravenous cidofovir would add significantly to agents available to treat this debilitating opportunistic infection.\n\nIn this two-part study, patients are stratified by age (3 months to \\< 2 years versus 2 years to \\< 13 years). In Part A, 8 patients (4 per cohort) receive a single intravenous dose of cidofovir with concurrent probenecid. If 1 patient in a cohort experiences life-threatening grade 3/4 toxicity, accrual for that cohort is stopped. If 1 patient in a cohort experiences non-life-threatening grade 3/4 toxicity, 2 additional patients are entered in that cohort. A second dose of cidofovir may be studied in Part A based on the pharmacokinetic and safety data obtained with the initial dose. Patients who complete Part A of the study without serious toxicity may be treated in Part B.\n\nIn Part B, 12 patients (8 in the older cohort and 4 in the younger cohort) receive maintenance therapy with cidofovir at the dose established in Part A. Patients who complete 6 months of treatment in Part B may continue therapy until all patients have completed the study. NOTE: For patients who require induction or reinduction, cidofovir is given weekly for 2 weeks before initiating the Part B regimen.\n\n\\[AS PER AMENDMENT 1/7/98: Each subject receives sequential single doses of intravenous cidofovir, with a 2-week interval between doses and with concurrent probenecid. If the single doses prove safe and well tolerated and individual pharmacokinetic profiles are acceptable, subjects proceed to multi-dosing cidofovir given every 2 weeks for 6 months beginning 14-21 days after the second single dose. Subjects remain on intravenous or oral ganciclovir for treatment of CMV retinitis until they enter the multi-dosing phase of the study. Subjects who require reinduction during the multi-dosing phase receive intravenous cidofovir once weekly for 2 weeks before resuming the every-2-weeks regimen. Patients are stratified by age (3 months to \\< 2 years vs. 2 years to \\< 13 years), with 4 patients entered in the younger cohort and 8 in the older. In the younger age cohort, if 1 patient experiences life- or vision-threatening grade 3/4 toxicity or 2 experience non-life-threatening grade 3/4 toxicity, the age cohort will stop. If 1 patient experiences non-life-threatening grade 3/4 toxicity, 2 additional patients will be enrolled in this age cohort. In the older age cohort, if 1 patient experiences severe life- or vision-threatening toxicity or 2 experience serious, non-life-threatening toxicities, enrollment for both cohorts will be suspended while safety data are reviewed. If 2 of the 8 patients experience severe, non-life-threatening toxicity, enrollment may continue.\\]"}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD"], "maximumAge"=>"13 years", "minimumAge"=>"3 months", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria\n\nConcurrent Medication:\n\nAllowed:\n\n* Ganciclovir therapy (for patients on Part A).\\[AS PER AMENDMENT 1/7/98:\n\nGanciclovir required during sequential single-dose phase.\\]\n\n* Antiretroviral medications, including protease inhibitors.\n* Antibacterials except for aminoglycosides.\n* IVIG.\n* Antihistamines, antiemetics, and acetaminophen.\n\nPatients must have:\n\n* Documented laboratory evidence of HIV-1 infection as demonstrated by:\n\n\\< 18 months of age:\n\n* a positive viral culture and a second confirmatory test (from a later date) of either a positive viral culture, p24 antigen, or PCR.
