DIAGNOSIS

He was diagnosed with meningococcal meningitis with C6 deficiency.

INTERVENTIONS

He was treated with intravenous ceftriaxone. An additional dose of quadrivalent meningococcal conjugate vaccine was administered after discharge.

LESSONS

Screening for complement deficiency is necessary in patients with a history of recurrent meningococcal infections to provide appropriate care and prevent recurrent infections.
