Real time quaking-induced conversion analysis of cerebrospinal fluid in sporadic Creutzfeldt-Jakob disease.
OBJECTIVE Current cerebrospinal fluid (CSF) tests for sporadic Creutzfeldt-Jakob disease (sCJD) are based on the detection of surrogate markers of neuronal damage such as CSF 14-3-3, which are not specific for sCJD. A number of prion protein conversion assays have been developed, including real time quaking-induced conversion (RT-QuIC). The objective of this study is to investigate whether CSF ...
متن کاملReal-Time Quaking-Induced Conversion Analysis for the Diagnosis of Sporadic Creutzfeldt-Jakob Disease in Korea
BACKGROUND AND PURPOSE The level of 14-3-3 protein in the cerebrospinal fluid (CSF) is increased in Creutzfeldt-Jakob disease (CJD) patients, which has led to it being used as a clinical biomarker for the ante-mortem diagnosis of human prion diseases. However, the specificity of the 14-3-3 protein is less reliable for CJD diagnosis. Newly developed assays including real-time quaking-induced con...
متن کاملCerebrospinal fluid real-time quaking-induced conversion test for sporadic Creutzfeldt–Jakob disease in an 18-year-old woman
RATIONALE Sporadic Creutzfeldt-Jakob disease (sCJD) mainly occurs in the elderly, with the peak age of onset ranging from 55 to 75 years. The symptoms of sCJD are not unique, and laboratory tests such as magnetic resonance imaging (MRI), electroencephalogram (EEG) and cerebrospinal fluid (CSF)14-3-3 protein have low sensitivity or specificity. Therefore, excluding treatable diseases and establi...
متن کاملPrion Diagnosis: Application of Real-Time Quaking-Induced Conversion
Prions composed of pathogenic scrapie prion protein (PrPSc) are infectious pathogens that cause progressive neurological conditions known as prion diseases or transmissible spongiform encephalopathies. Although these diseases pose considerable risk to public health, procedures for early diagnosis have not been established. One of the most recent attempts at sensitive and specific detection of p...
متن کاملCerebrospinal fluid real‐time quaking‐induced conversion is a robust and reliable test for sporadic creutzfeldt–jakob disease: An international study
Real-time quaking-induced conversion (RT-QuIC) has been proposed as a sensitive diagnostic test for sporadic Creutzfeldt-Jakob disease; however, before this assay can be introduced into clinical practice, its reliability and reproducibility need to be demonstrated. Two international ring trials were undertaken in which a set of 25 cerebrospinal fluid samples were analyzed by a total of 11 diffe...
