Purpose: To study the characteristics of uveitis occurring during intravenous cidofovir treatment for CMV retinitis in patients with AIDS.
Patients And Methods: We retrospectively studied ten cases (16 eyes) of uveitis in patients with CMV retinitis treated with intravenous cidofovir. All the patients had ophthalmologic examinations and, if required, fundus angiographies. The median follow-up was eight months.
Results: Uveitis occurred after a mean of 8.5 infusions of cidofovir (range 2-17). All ten patients were on protease inhibitors. The mean CD4+ cell count was 92 +/- 51/microl and the median viral load was 3.9 log. All the eyes with uveitis had healed CMV retinitis. The first examination of the involved eyes showed inflammation of the anterior chamber (100%), vitritis (50%), posterior synechiae (75%), and low intraocular pressure (94%). Uveitis did not relapse in the seven patients who stopped cidofovir, whereas it relapsed in two of the three patients who did not stop treatment. At the end of follow-up, permanent posterior synechiae were present in 69% of the involved eyes.
Comments: Cidofovir therapy necessitates slit-lamp surveillance, especially in patients on HAART. Cidofovir-related uveitis requires a local steroid treatment, but if possible, cidofovir should be withdrawn.

Article Synopsis
- Cytomegalovirus retinitis (CMVR) is a major cause of blindness in advanced AIDS patients, with varied treatment approaches due to the lack of established guidelines.
- A review of 59 studies revealed an 18% improvement in visual acuity and a 90% rate of inflammation resolution, with ganciclovir being the most commonly used antiviral treatment.
- Notably, patients on antiretroviral therapy (ART) had a significantly lower recurrence rate of inflammation compared to those not on ART, and the most common side effect reported was neutropenia related to ganciclovir.
A randomized, placebo-controlled, dose-escalation phase I/II multicenter trial of low-dose cidofovir for BK polyomavirus nephropathy.

Department of Internal Medicine, University of Washington, Seattle, Washington, USA.
Background: BK polyomavirus-associated nephropathy (BKPyVAN) is an important cause of allograft dysfunction and failure in kidney transplant recipients (KTRs) and there are no proven effective treatments. Case reports and in vitro data support the potential activity of cidofovir against BK polyomavirus (BKPyV).
Methods: We report the results of a phase I/II, double-blind, placebo-controlled randomized dose-escalation trial of cidofovir in KTRs with biopsy-confirmed BKPyVAN and estimated glomerular filtration rate ≥30 mL/min.

Article Synopsis
- A patient with HIV had serious eye problems from a virus called CMV because their medicine wasn't working anymore.
- Doctors tried different treatments, but they weren't successful, so they combined several medicines to try and help the patient.
- Even though the new treatment worked for a while, the patient still had to deal with a weakened immune system and problems with the virus coming back.
Nephrotoxicity of Intravenous Ganciclovir in Pediatric Hematopoietic Cell Transplant Recipients.
Pediatr Infect Dis J

From the Department of Pediatrics, University of Michigan.
Background: Associations between ganciclovir and severe nephrotoxicity are incompletely defined. Studies incorporating the time-varying nature of medication exposures and those that address confounding by indication are particularly scarce in children undergoing hematopoietic cell transplantation.
Methods: We identified children undergoing hematopoietic cell transplantation in the Pediatric Health Information System database and tracked them for 1 year following transplantation.
