A case study: the use of cidofovir for the management of progressive multifocal leukoencephalopathy.

Progressive Multifocal Leukoencephalopathy (PML) is an opportunistic infection of the brain in advanced stages of AIDS. PML is caused by the JC virus, which leads to a decline in mental acuity and motor functions over a period of weeks or months. Currently, there is no treatment or cure for PML. Cidofovir, an antiviral agent, at the standard dosages for the treatment of cytomegalovirus (CMV) was implemented in the treatment and management of a 35-year-old, newly diagnosed AIDS, White male with PML. The patient presented with impaired motor functions of the left upper and lower extremities, which resulted in hemiparalysis and hemiparesis. The use of cidofovir infusions at standard recommendations for treatment and management of CMV has resulted in improvement and some resolution of the patient's paralysis and paresthesia. The patient has remained on the cidofovir for more than a year, with no signs of advancement of his PML or AIDS. Further investigation and extensive clinical trials are needed in the treatment and management of PML with the use of cidofovir.
