背景情况:
- 渐进性多焦点白内障 (PML) 是一种严重的中枢神经系统感染,由JC病毒 (JCV) 引起.
- 在免疫抑制患者中,PML是已知的并发症,包括那些接受移植,化疗或服用特定免疫调节药物 (如纳塔利祖马布或瑞图西马布) 的患者.
- 目前的诊断标准依赖于通过PCR在脑脊液 (CSF) 中检测JCVDNA,以及临床和MRI证据.
研究的目的:
- 突出目前的JC病毒 (JCV) PCR报告中的一个关键缺陷,用于诊断渐进式多焦细胞白内障 (PML).
- 倡导在JCV PCR报告中强制包含测试指标,如量化限度 (LOQ) 和检测限度 (LOD).
- 提高诊断透明度,防止错过或延迟的PML诊断.
主要方法:

Overview
PCR - Polymerase Chain Reaction
Overview
Real Time RT-PCR
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.

Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

Rapid Identification of Pathogens
MALDI-TOF MS has transformed clinical microbiology by offering a rapid and reliable method for pathogen identification. The traditional approach to microbial identification typically involves time-consuming culture techniques and biochemical tests, which can delay the initiation of appropriate antimicrobial therapy. MALDI-TOF MS avoids these delays by using characteristic ribosomal protein mass patterns of microbial cells, enabling accurate species-level identification within minutes.Principle...
Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
