Waterhouse–Friderichsen syndrome

Waterhouse–Friderichsen syndrome (WFS) is defined as adrenal gland failure due to bleeding into the adrenal glands, commonly caused by severe bacterial infection. Typically, it is caused by Neisseria meningitidis.[1]

SpecialtyEndocrinology 
CausesBacterial infection

The bacterial infection leads to massive bleeding into one or (usually) both adrenal glands.[2] It is characterized by overwhelming bacterial infection meningococcemia leading to massive blood invasion, organ failure, coma, low blood pressure and shock, disseminated intravascular coagulation (DIC) with widespread purpura, rapidly developing adrenocortical insufficiency and death.

Signs and symptoms

Waterhouse-Friderichsen Syndrome can be caused by a number of different organisms (see below). When caused by Neisseria meningitidis, WFS is considered the most severe form of meningococcal sepsis. The onset of the illness is nonspecific with fever, rigors, vomiting, and headache. Soon a rash appears; first macular, not much different from the rose spots of typhoid, and rapidly becoming petechial and purpuric with a dusky gray color. Low blood pressure (hypotension) develops and rapidly leads to septic shock. The cyanosis of extremities can be extreme and the patient is very prostrated or comatose. In this form of meningococcal disease, meningitis generally does not occur. Low levels of blood glucose and sodium, high levels of potassium in the blood, and the ACTH stimulation test demonstrate the acute adrenal failure. Leukocytosis need not be extreme and in fact leukopenia may be seen and it is a very poor prognostic sign. C-reactive protein levels can be elevated or almost normal. Thrombocytopenia is sometimes extreme, with alteration in prothrombin time (PT) and partial thromboplastin time (PTT) suggestive of disseminated intravascular coagulation (DIC). Acidosis and acute kidney failure can be seen as in any severe sepsis. Meningococci can be readily cultured from blood or cerebrospinal fluid, and can sometimes be seen in smears of cutaneous lesions. Difficulty swallowing, atrophy of the tongue, and cracks at the corners of the mouth are also characteristic features.

Causes

Multiple species of bacteria can be associated with the condition:

Viruses may also be implicated in adrenal problems:

  • Cytomegalovirus can cause adrenal insufficiency,[7] especially in the immunocompromised.
  • Ebola virus infection may also cause similar acute adrenal failure.

Diagnosis

Diagnostic criteria is based on clinical features of adrenal insufficiency as well as identifying the causal agent. If the causal agent is suspected to be meningitis a lumbar puncture is performed. If the causal agent is suspected to be bacterial a blood culture and complete blood count is performed. An adrenocorticotropic hormone stimulation test can be performed to assess adrenal function.

Prevention

Routine vaccination against meningococcus is recommended by the Centers for Disease Control and Prevention for all 11- to 18-year-olds and people who have poor splenic function (who, for example, have had their spleen removed or who have sickle-cell disease which damages the spleen), or who have certain immune disorders, such as a complement deficiency.[8]

Treatment

Fulminant infection from meningococcal bacteria in the bloodstream is a medical emergency and requires emergent treatment with vasopressors, fluid resuscitation, and appropriate antibiotics. Benzylpenicillin was once the drug of choice with chloramphenicol as a good alternative in allergic patients. Ceftriaxone is an antibiotic commonly employed today. Hydrocortisone can sometimes reverse the adrenal insufficiency. Amputations, reconstructive surgery, and tissue grafting are sometimes needed as a result of tissue necrosis (typically of the extremities) caused by the infection.

History

Waterhouse–Friderichsen syndrome is named after Rupert Waterhouse (1873–1958), an English physician, and Carl Friderichsen (1886–1979), a Danish pediatrician, who wrote papers on the syndrome, which had been previously described.[9][10]
