From the Guidelines

The treatment for meningococcemia requires immediate administration of antibiotics, with ceftriaxone (2g IV every 12 hours for adults) or cefotaxime (2g IV every 4-6 hours for adults) being the first-line options, as recommended by the most recent guidelines 1.

Key Considerations

  • In penicillin-susceptible cases, high-dose penicillin G (4 million units IV every 4 hours) can be used.
  • Treatment typically continues for 7-10 days.
  • Supportive care is crucial and includes:
    • Fluid resuscitation
    • Vasopressors for shock
    • Mechanical ventilation if needed
    • Close monitoring in an intensive care setting
  • Corticosteroids may be considered in certain cases, particularly when meningitis is present.

Chemoprophylaxis

  • Chemoprophylaxis should be given to close contacts using rifampin, ciprofloxacin, or ceftriaxone to prevent secondary cases, as outlined in the ESCMID guideline 1.
  • The recommended dose of prophylactic antibiotic treatment for household contacts and other close contacts of meningococcal meningitis patients is specified in Table 4.3 of the ESCMID guideline 1.
  • Ciprofloxacin is now recommended in preference to rifampicin in all age groups and in pregnancy, due to its single-dose regimen and availability 1.

Importance of Prompt Treatment

  • Prompt treatment is essential as meningococcemia is a medical emergency with high mortality if not treated quickly.
  • The antibiotics work by killing the Neisseria meningitidis bacteria, preventing further toxin release and halting the progression of the infection and its life-threatening complications such as septic shock and disseminated intravascular coagulation.

From the FDA Drug Label

In the treatment of meningitis, it is recommended that the initial therapeutic dose be 100 mg/kg (not to exceed 4 grams). Ceftriaxone for Injection is indicated for the treatment of the following infections when caused by susceptible organisms: ... MENINGITIS Caused by Haemophilus influenzae, Neisseria meningitidis or Streptococcus pneumoniae

The treatment for meningococcemia, which is caused by Neisseria meningitidis, is ceftriaxone. The recommended dose is an initial therapeutic dose of 100 mg/kg (not to exceed 4 grams), followed by a total daily dose of 100 mg/kg/day (not to exceed 4 grams daily) 2.

From the Research

Treatment for Meningococcemia

The treatment for meningococcemia, a life-threatening illness caused by the bacterium Neisseria meningitidis, requires prompt antibiotic treatment. The following are some key points to consider:

  • Antibiotic treatment is essential for patients with meningococcemia, and close contacts may require antibiotic prophylaxis to prevent the spread of the disease 3.
  • The choice of antibiotic depends on various factors, including the susceptibility of the Neisseria meningitidis isolate and the presence of antibiotic resistance 4, 5, 6.
  • Ceftriaxone, penicillin, and ciprofloxacin are commonly used antibiotics for the treatment of meningococcemia, but resistance to these antibiotics has been reported 5, 6.
  • Alternative antibiotic options, such as rifampin and azithromycin, may be considered in areas with high levels of antibiotic resistance 3, 4.
  • Short-term treatment with ceftriaxone has been shown to be effective in adults with meningococcal meningitis, but careful follow-up is necessary to ensure that the infection is fully cleared 7.

Antibiotic Resistance

Antibiotic resistance is a significant concern in the treatment of meningococcemia, and monitoring of antibiotic resistance patterns is essential to guide treatment decisions. Some key points to consider:

  • Resistance to penicillin and ciprofloxacin has been reported in Neisseria meningitidis isolates from various parts of the world 5, 6.
  • Ceftriaxone remains a highly effective antibiotic against Neisseria meningitidis, but resistance to this antibiotic has also been reported 6.
  • The use of rifampin and other antibiotics may lead to the emergence of resistant isolates, highlighting the need for careful monitoring of antibiotic resistance patterns 4.

Treatment Options

The following are some treatment options for meningococcemia:

  • Ceftriaxone: a broad-spectrum cephalosporin antibiotic that is effective against Neisseria meningitidis 4, 7.
  • Penicillin: a commonly used antibiotic for the treatment of meningococcemia, but resistance to this antibiotic has been reported 5, 6.
  • Ciprofloxacin: a fluoroquinolone antibiotic that is effective against Neisseria meningitidis, but resistance to this antibiotic has been reported 3, 4, 6.
  • Rifampin: an antibiotic that is effective against Neisseria meningitidis, but may lead to the emergence of resistant isolates 4.
  • Azithromycin: a macrolide antibiotic that may be considered as an alternative treatment option in areas with high levels of antibiotic resistance 3, 4.
