A Study of the Mechanisms of Infection Susceptibility Across the Life Course and the Development of an Intelligent Prevention and Control System
This multicenter, observational registry study aims to characterize host immune, genetic, and microbiome features associated with susceptibility to infection and the risk of severe infection in adults. Approximately 2,195 adults aged 18 years or older undergoing routine health examinations or health screening will be enrolled and followed prospectively for five years. Available clinical information and previously stored biological samples collected since 2019 will also be retrospectively integrated. Demographic characteristics, medical history, medication use, vaccination history, laboratory findings, infection events, treatments, hospitalizations, intensive care admissions, and clinical outcomes will be recorded. Blood, urine, stool, sputum, and nasopharyngeal or oropharyngeal samples will be collected when available to evaluate host immune responses, genetic characteristics, biomarkers, and microbial composition and function. By integrating longitudinal clinical data with biological measurements, the study seeks to identify potential biomarkers and improve infection-risk prediction beyond conventional clinical factors, thereby supporting risk stratification and the development of personalized infection-prevention strategies.

Number of the Composite Endpoint of Death or Severe Infection
時間枠:From baseline to Year 5
|
Number of participants experiencing at least one component of the composite endpoint: all-cause death, infection-related death, or severe infection. Severe infection will be evaluated based on clinically documented outcomes, including infection-related hospitalization, intensive care unit admission, mechanical ventilation, or other life-threatening infection events. |
