简要总结
Infectious disease leads to deaths that accounted for more than 25% of all causes of human mortality. But the traditional microbiological diagnostic methods such as specimen culture are sometimes time-consuming, and have limited sensitivity. And some bacteria, anaerobes and viruses may be difficult to cultivate and isolation. Therefore, the accurate identification and rapid classification of pathogenic microorganisms is very important for the patient's precise diagnosis and timely treatment.
Small-scale studies on the diagnostic efficacy and prognosis of infection in the next generation have been shown to provide early diagnosis and targeted medication guidance for bloodstream infections and respiratory infections, but the larger-scale validation of next-generation sequencing Technology in the diagnosis and treatment of infectious diseases in the human body is relatively rare.
The purpose of this study is to provide rapid etiological diagnosis of patients by means of next-generation sequencing, to change the way of treatment of patients under the existing traditional pathogen detection by means of accurate description of pathogens and monitoring their dynamic changes, and to provide patients with more accurate treatment.

结局指标
主要结局
Diagnostic value (sensitivity and sensibility, positive/negative predictive value) of next-generation sequencing in the pathogen detection of infectious diseases
时间窗: 3 years
We aim to collect samples from patients with fever, bacteremia and bloodstream infections, respiratory infections, central nervous system infections, and abscesses, including blood, cerebrospinal fluid, serous effusion, pus, sputum, alveolar lavage fluid, throat swab. Next-generation sequencing will be performed on the collected samples. Our analysis of the sequencing results will focus on the analysis and identification of pathogen genes and will compare the diagnostic performance of next-generation sequencing with conventional etiological diagnostic methods. We anticipate that next-generation sequencing in infectious patients will show a greater diagnostic value than the traditional methods (including culture, special pathogen serology, PCR detection of nucleic acids, etc.).
