SARS: prognosis, outcome and sequelae
Respirology (Carlton, Vic.)
|March 17, 2004
Summary
Severe acute respiratory syndrome (SARS) can cause significant illness and death. Long-term health issues, including lung problems and psychological distress, may persist after recovery, requiring ongoing patient monitoring.
Area of Science:
- Infectious Diseases
- Pulmonology
- Public Health
Background:
- Severe acute respiratory syndrome (SARS) presents significant morbidity and mortality.
- Prognostic factors like age and comorbidities are known, but viral and host factors' impact remains unclear.
- Limited data exists on the long-term health consequences (sequelae) following SARS recovery.
Purpose of the Study:
- To review and summarize the known and potential long-term sequelae of SARS.
- To highlight the need for continued follow-up of SARS survivors.
- To inform management strategies for persistent or emerging health issues.
Main Methods:
- Review of published literature on SARS clinical outcomes and follow-up studies.
- Analysis of reported radiological, functional, and psychological abnormalities post-SARS.
- Identification of potential complications such as pulmonary fibrosis and avascular necrosis.
Main Results:
- Survivors may experience varying degrees of radiological, functional (weakness, shortness of breath), and psychological abnormalities.
- Pulmonary fibrosis, restrictive lung patterns, and decreased carbon monoxide diffusing capacity are reported.
- Anxiety, depression, and avascular necrosis of the hip are noted complications, with most psychological issues improving over time.
Conclusions:
- While some SARS sequelae may improve, long-term effects are not fully understood.
- Continued patient follow-up is crucial for managing persistent or emerging physical, psychological, and social issues.
- Further research is needed to fully characterize the long-term impact of SARS.
