Meningococcemia

Meningococcal septicemia; Meningococcal blood poisoning; Meningococcal bacteremia

 

Meningococcemia is an acute and potentially life-threatening infection of the bloodstream.

Causes

 

Meningococcemia is caused by bacteria called Neisseria meningitidis. The bacteria often live in a person's upper respiratory tract without causing signs of illness. They can be spread from person to person through respiratory droplets. For example, you may become infected if you are around someone with the condition and they sneeze or cough.

Family members and those closely exposed to someone with the condition are at increased risk. The infection occurs more often in winter and early spring.

 

Symptoms

 

There may be few symptoms at first. Some may include:

  • Fever
  • Headache
  • Irritability
  • Muscle pain
  • Nausea
  • Rash with very small red or purple spots on the feet or legs

Later symptoms may include:

  • A decline in your level of consciousness
  • Large areas of bleeding under the skin
  • Shock

 

Exams and Tests

 

The health care provider will examine you and ask about your symptoms.

Blood tests will be done to rule out other infections and help confirm meningococcemia. Such tests may include:

  • Blood culture
  • Complete blood count with differential
  • Blood clotting studies

Other tests that may be done include:

  • Lumbar puncture to get a sample of spinal fluid for culture
  • Skin biopsy and Gram stain
  • Urine analysis

 

Treatment

 

Meningococcemia is a medical emergency. People with this infection are often admitted to the intensive care unit of the hospital, where they are closely monitored. They may be placed in respiratory isolation for the first 24 hours to help prevent the spread of the infection to others.

Treatments may include:

  • Antibiotics given through a vein immediately
  • Breathing support
  • Clotting factors or platelet replacement, if bleeding disorders develop
  • Fluids through a vein
  • Medicines to treat low blood pressure
  • Wound care for areas of skin with blood clots

 

Outlook (Prognosis)

 

Early treatment results in a good outcome. When shock develops, the outcome is less certain.

The condition is most life threatening in those who have:

  • A severe bleeding disorder called disseminated intravascular coagulopathy (DIC)
  • Kidney failure
  • Shock

 

Possible Complications

 

Possible complications of this infection are:

  • Arthritis
  • Bleeding disorder (DIC)
  • Gangrene due to lack of blood supply
  • Inflammation of blood vessels in the skin
  • Inflammation of the heart muscle
  • Inflammation of the heart lining
  • Shock
  • Severe damage to adrenal glands that can lead to low blood pressure (Waterhouse-Friderichsen syndrome)

 

When to Contact a Medical Professional

 

Go to the emergency room immediately if you have symptoms of meningococcemia. Call your provider if you have been around someone with the disease.

 

Prevention

 

Preventive antibiotics for family members and other close contacts are often recommended. Speak with your provider about this option.

A vaccine that covers some, but not all, strains of meningococcus is recommended for children age 11 or 12. A booster is given at age 16. Unvaccinated college students who live in dormitories should also consider receiving this vaccine. It should be given a few weeks before they first move into the dorm. Talk to your provider about this vaccine.
