ABSTRACT
Introduction
Invasive meningococcal disease (IMD) caused by Neisseria meningitidis is a disease with a high mortality and morbidity rate. Serogroup W meningococci (MenW) used to be associated with sporadic disease worldwide. In recent years, a surge in MenW incidence is being observed.
Report
An older adult presenting with acute onset shortness of breath, chest pain and fever, was diagnosed with pericarditis with meningococcemia due to MenW:ST11 strain. MenW infections are reported to have a higher case fatality rate and atypical clinical presentations: MenW has been identified in patients presenting with pneumonia, gastro-intestinal symptoms, arthritis, and pericarditis.
Discussion
In Belgium, the National Reference Laboratory is also noticing an increase in serogroup Wmeningococcal disease. Recent epidemiological data for Belgium is reported in the article. MenW infections are reported to have a higher case fatality rate and atypical clinical presentations: MenW has been identified in patients presenting with pneumonia, gastro-intestinal symptoms, arthritis, and pericarditis.
Conclusion
When factors for poor prognosis are present in patients with pericarditi clinicians should be vigilant and search for the underlying aetiology .
