Detection of JC virus infection in progressive multifocal leukoencephalopathy: the first documented case in Thailand.
ABSTRACT Progressive Multifocal Leukoencephalopathy (PML) is a demyelinating brain disease caused by human polyoma JC virus (JCV). This disease is an important cause of morbidity and mortality in AIDS patients. Definite diagnosis currently requires a brain biopsy. PCR for JCV of CSF, an emerging diagnostic tool, has a high specificity for the diagnosis of PML in patients with characteristics on clinical and neuroradiological findings. The authors report a 36-year-old woman who presented with prolonged fever, progressive weakness, and slow speech for 2 months. Clinical features and MRI findings were compatible with PML. Qualitative PCR for JCV of CSF showed a positive result. This report emphasizes the yield of PCR, the CSF for JCV in a diagnosis of PML, which may reduce the need for a brain biopsy in such cases.
Article: Frequent detection of Epstein-Barr Virus and cytomegalovirus but not JC virus DNA in cerebrospinal fluid samples from human immunodeficiency virus-infected patients in northern Thailand.[show abstract] [hide abstract]
ABSTRACT: Applying nested-PCRs, we frequently detected DNA of Epstein-Barr virus and cytomegalovirus but not JC virus in cerebrospinal fluid samples from 140 human immunodeficiency virus-infected patients with central nervous system symptoms in northern Thailand. Despite the low incidence of primary central nervous system lymphoma or cytomegalovirus encephalitis among Thai AIDS patients, Epstein-Barr virus and cytomegalovirus infections in the central nervous system are common.Journal of Clinical Microbiology 08/2005; 43(7):3484-6. · 4.15 Impact Factor
