Humanized Mouse Model to Study Bacterial Infections Targeting the Microvasculature
Published on: April 1, 2014
Abstract:
In a prospective case control study in Norway during the winter 1981-1982, 115 patients with systemic meningococcal disease were compared with 61 patient controls. Initially, skin bleedings, reduced general condition and consciousness, and body pain were seen more often, but irritability less often in meningococcal patients than in the patient controls. The meningococcal patients presented symptoms typical of infectious diseases in general. Symptoms that correlated with a poor prognosis of the meningococcal disease were reduced consciousness, cyanosis, and early diarrhea. The mean time interval from start of the meningococcal disease until admission to hospital was 34 hours. No deaths occurred when less than six hours elapsed before it was decided to admit the patient. All fatal cases were admitted by the first doctor who saw the meningococcal patient. Contact with the family doctor does not seem to have reduced the risk of death. To avoid unnecessary delays, access to hospitals should be facilitated, and efforts should be made to shorten the time interval before patients with relevant symptoms are seen by a doctor.
Insights
Early hospital admission is crucial for improving outcomes in systemic meningococcal disease. Prompt medical attention for symptoms like reduced consciousness can significantly reduce mortality risk.
Area of Science:
- Epidemiology
- Infectious Diseases
- Clinical Medicine
Background:
- Systemic meningococcal disease (SMD) presents with varied symptoms, making early diagnosis challenging.
- Understanding prognostic factors and delays in care is vital for improving patient outcomes.
Purpose of the Study:
- To identify early symptoms and prognostic indicators of systemic meningococcal disease.
- To analyze the impact of time to hospital admission on mortality.
Main Methods:
- Prospective case-control study comparing 115 SMD patients with 61 controls in Norway (1981-1982).
- Data collection included initial symptoms, general condition, consciousness, and time intervals to medical care.
Main Results:
- Initial symptoms like skin bleeding and reduced consciousness were more frequent in SMD patients.
- Reduced consciousness, cyanosis, and early diarrhea correlated with a poor prognosis.
- A mean delay of 34 hours from symptom onset to hospital admission was observed; no deaths occurred with admission decisions within 6 hours.
Conclusions:
- Facilitating hospital access and reducing delays in medical evaluation are critical for minimizing mortality.
- Early recognition and prompt management of systemic meningococcal disease are essential for better patient survival.
