Waterhouse-Friderichsen syndrome
Waterhouse-Friderichsen syndrome (WFS) is a group of symptoms caused when the adrenal glands fail to function normally. This occurs as a result of bleeding into the glands.
Causes
The adrenal glands are two triangle-shaped glands. One gland is located on top of each kidney. The adrenal glands produce and release different hormones that the body needs to function normally. The adrenal glands can be affected by many diseases, such as infections like WFS.
Adrenal glands
The adrenal glands are two small triangle-shaped glands in the upper abdomen. One gland is located on top of each kidney.
Read Article Now Book Mark ArticleWFS is caused by severe infection with meningococcus bacteria or other bacteria such as:
- Group B streptococcus
- Pseudomonas aeruginosa
- Streptococcus pneumoniae
- Staphylococcus aureus
Symptoms
Symptoms occur suddenly. They are due to the bacteria growing in large numbers inside the body. Symptoms include:
- Fever and chills
- Joint and muscle pain
- Headache
- Vomiting
The infection with bacteria causes bleeding throughout the body, which causes:
- A rash throughout the body
- Disseminated intravascular coagulation in which small blood clots cut off blood supply to the organs
Disseminated intravascular coagulation
Disseminated intravascular coagulation (DIC) is a serious disorder in which the proteins that control blood clotting become overactive.

Bleeding into the adrenal glands makes the glands unable to produce enough adrenal hormones. This is called adrenal crisis, and it leads to symptoms such as:
- Dizziness, weakness
- Very low blood pressure
- Very fast heart rate
- Confusion or coma
Exams and Tests
Your health care provider will perform a physical exam and ask about your symptoms.
Blood tests will be done to confirm a bacterial infection. Tests may include:
- Blood culture

Treatment
Antibiotics are started right away to treat the bacterial infection. Glucocorticoid medicines will also be given to treat adrenal gland insufficiency. Supportive treatments will be needed for other symptoms.
Outlook (Prognosis)
WFS is fatal unless treatment for the bacterial infection is started right away and glucocorticoid drugs are given.
Prevention
To prevent WFS caused by meningococcal bacteria, a vaccine is available.
