Invasive meningococcal disease (IMD) frequency has declined since 1977. Sepsis-only cases show higher mortality, while dexamethasone and phenytoin offer potential benefits for managing IMD complications.
Area of Science:
- Infectious Diseases
- Epidemiology
- Clinical Medicine
Background:
- Invasive meningococcal disease (IMD) remains a significant public health concern, with mortality rates between 5% and 16%.
- A large cohort study was conducted to enhance understanding of IMD in adults over an extended period.
Purpose of the Study:
- To analyze a long-term cohort of Invasive Meningococcal Disease (IMD) cases.
- To compare outcomes between IMD with sepsis only versus meningitis with sepsis.
- To evaluate the impact of dexamethasone and prophylactic phenytoin on IMD outcomes.
Main Methods:
- An observational cohort study included 527 IMD patients from 1977 to 2013.
- Comparison of sepsis-only versus meningitis with sepsis groups.
- Analysis of dexamethasone and phenytoin efficacy, and sequelae (cutaneous, neurological).
Main Results:
- IMD incidence decreased significantly over time (67% to 4%).
- Overall mortality was 6% (14% for sepsis-only, 5% for meningitis).
- Dexamethasone use was safe, reducing arthritis; phenytoin prevented seizures.
Conclusions:
- IMD frequency has sharply decreased.
- Sepsis-only IMD carries the highest mortality and complication rates.
- Dexamethasone is safe and may prevent arthritis; phenytoin may benefit selected patients.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
