Recurrent meningococcal meningitis. A case report
Abstract:
A 17-year-old Coloured youth presented at Tygerberg Hospital on six occasions between 1978 and 1981. He was admitted three times for meningococcal meningitis and three times for a meningitic illness clinically suggestive thereof. He had been admitted twice before to the City Hospital, Cape Town, in 1966 and 1968, for presumed meningococcal meningitis. He was fully evaluated in the outpatient department and found to have no detectable total haemolytic complement activity. There was no evidence of classic or alternative pathway activation. He has been tentatively designated as having a deficiency in the C6 or C8 components of the terminal membrane attack mechanism of the complement cascade.
Insights
A young patient with recurrent meningitis was found to have a deficiency in complement cascade components C6 or C8. This immune deficiency likely explains his repeated severe infections.
Area of Science:
- Immunology
- Infectious Diseases
Background:
- Recurrent meningococcal meningitis poses a significant health challenge.
- Complement system deficiencies can lead to increased susceptibility to infections.
Observation:
- A 17-year-old male experienced multiple admissions for meningococcal meningitis and related illnesses.
- Previous hospitalizations for presumed meningococcal meningitis were noted.
Findings:
- The patient exhibited no detectable total haemolytic complement activity.
- No evidence of classic or alternative pathway activation was found.
- A deficiency in C6 or C8 complement components of the terminal membrane attack complex was tentatively diagnosed.
Implications:
- This case highlights the importance of investigating complement deficiencies in patients with recurrent severe bacterial meningitis.
- Identifying specific complement component deficiencies can guide management and genetic counseling.
- Understanding the terminal membrane attack pathway's role is crucial for preventing invasive meningococcal disease.
