    Summary

    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.
