Patient data, early SARS epidemic, Taiwan.

Area of Science:

• Infectious Diseases
• Immunology
• Pulmonology

Background:

• The severe acute respiratory syndrome (SARS) epidemic presented unique clinical challenges.
• Understanding the early clinical manifestations and associated immune responses is crucial for disease management.

Purpose of the Study:

• To describe the clinical and immunological characteristics of the first 10 SARS patients in Taiwan.
• To identify potential early indicators and associated syndromes in SARS patients.

Main Methods:

• Retrospective analysis of clinical data from 10 confirmed SARS cases.
• Assessment of symptoms, including gastrointestinal issues and presence of hemophagocytosis syndrome.
• Measurement of serum cytokine levels (IL-6, IL-8, TNF-a) and evaluation of lung lesions.

Main Results:

• Four of the 10 patients had close contact with a SARS case on an airplane, suggesting potential transmission routes.
• All 10 patients presented with loose stools or diarrhea.
• Hemophagocytosis syndrome was observed in all 10 patients.
• Elevated serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-a) were detected in all patients.
• Lung lesions were a consistent finding across all cases.

Conclusions:

• Early SARS cases in Taiwan exhibited significant gastrointestinal symptoms and hemophagocytosis syndrome.
• High levels of pro-inflammatory cytokines (IL-6, IL-8, TNF-a) are strongly associated with SARS and lung pathology.
• These findings highlight the systemic inflammatory nature of SARS and the importance of monitoring these markers.
