Waterhouse–Friderichsen syndrome (WFS) is a rare, rapidly progressive, and life-threatening condition characterized by acute adrenal gland hemorrhage with adrenal insufficiency or adrenal crisis, most classically in the setting of fulminant meningococcemia caused by Neisseria meningitidis. It can also occur with other severe infections, coagulopathy, anticoagulant therapy, thrombotic disorders, trauma, or extreme physiologic stress.Waterhouse-Friderichsen Syndrome(link). StatPearls, NCBI Bookshelf.

The syndrome is a medical emergency. Patients may develop fever, vomiting, rapidly spreading petechiae or purpura, hypotension, septic shock, disseminated intravascular coagulation, electrolyte abnormalities, acute adrenal failure, coma, and death. Treatment requires immediate recognition, broad empiric antibiotics, aggressive resuscitation, intensive care, vasopressors when needed, and stress-dose hydrocortisone for suspected adrenal crisis.Clinical Guidance for Meningococcal Disease(link). Centers for Disease Control and Prevention."Guidance for the prevention and emergency management of adult patients with adrenal insufficiency".Clinical Medicine.2020;PMC:7385786.

Overview[edit]

Waterhouse–Friderichsen syndrome is best understood as the intersection of severe systemic illness, adrenal hemorrhage, and acute adrenal failure. The classic presentation is fulminant meningococcal sepsis with purpura fulminans and bilateral adrenal hemorrhage. However, modern case reports and reviews show that the syndrome is not limited to meningococcal disease and can occur in adults or children with other infections or noninfectious causes of adrenal bleeding.Waterhouse-Friderichsen Syndrome(link). StatPearls, NCBI Bookshelf."Waterhouse-Friderichsen Syndrome with Bilateral Adrenal Hemorrhage Secondary to Methicillin-Resistant Staphylococcus aureus Bacteremia".American Journal of Case Reports.2022;PMC:9016783.

The adrenal glands are highly vascular endocrine organs. During severe sepsis, shock, coagulopathy, or thrombosis, adrenal venous drainage can be overwhelmed, predisposing to hemorrhage. When both adrenal glands are affected, cortisol production may abruptly fall, worsening hypotension and shock.

Terminology[edit]

Anatomy and physiology[edit]

The adrenal glands sit above the kidneys and contain two major regions.

In Waterhouse–Friderichsen syndrome, adrenal hemorrhage can destroy adrenal cortical tissue or impair adrenal function, causing sudden cortisol deficiency during an already severe illness.

Causes[edit]

Meningococcal infection[edit]

The classic cause of WFS is fulminant infection with Neisseria meningitidis.

  • Neisseria meningitidis - Gram-negative diplococcus that can cause meningitis, meningococcemia, sepsis, and purpura fulminans.
  • Meningococcemia - Bloodstream infection that can progress rapidly.
  • Meningococcal meningitis - Meningitis may occur with meningococcemia but is not always present in WFS.
  • Endotoxin - Meningococcal lipooligosaccharide contributes to inflammatory shock.
  • Purpura fulminans - Severe manifestation of meningococcal sepsis.
  • Complement deficiency - Increases risk of invasive meningococcal disease.
  • Asplenia - Increases risk of severe infection with encapsulated bacteria.

Other bacterial causes[edit]

Many bacteria can rarely cause adrenal hemorrhage or WFS-like adrenal failure.

Viral, fungal, and opportunistic causes[edit]

  • Cytomegalovirus - Can involve the adrenal glands, especially in immunocompromised patients.
  • Ebola virus disease - Severe viral hemorrhagic fever may involve adrenal dysfunction.
  • HIV/AIDS - Can predispose to opportunistic adrenal infection or adrenal insufficiency.
  • Fungal infection - Disseminated fungal disease may involve adrenal glands.
  • Histoplasmosis - Can cause adrenal enlargement and adrenal insufficiency.
  • Candidemia - Rarely associated with adrenal involvement.

Noninfectious causes[edit]

Waterhouse–Friderichsen syndrome is classically infectious, but bilateral adrenal hemorrhage with acute adrenal crisis can also occur without meningococcemia.

  • Anticoagulant therapy - Warfarin, heparin, and direct oral anticoagulants may increase bleeding risk.
  • Antiphospholipid syndrome - Thrombotic disorder associated with adrenal hemorrhage.
  • Heparin-induced thrombocytopenia - Can cause adrenal vein thrombosis and hemorrhage.
  • Trauma - Blunt abdominal trauma can cause adrenal hemorrhage.
  • Major surgery - Severe postoperative stress may be associated with adrenal hemorrhage.
  • Burn injury - Severe physiologic stress can predispose to adrenal hemorrhage.
  • Pregnancy - Rare cases occur during pregnancy or postpartum.
  • Severe stress - Critical illness may contribute to adrenal bleeding.
  • Adrenal tumor - Hemorrhage into an adrenal mass can mimic or contribute to adrenal crisis.
  • Coagulopathy - Bleeding disorders increase risk.
  • Thrombocytopenia - Low platelet count increases bleeding risk.

Risk factors[edit]

CDC notes that people receiving complement inhibitors remain at substantial risk for meningococcal disease even with vaccination, and additional prophylaxis may be considered in selected patients.Clinical Guidance for Managing Meningococcal Disease Risk in Patients Receiving Complement Inhibitor Therapy(link). Centers for Disease Control and Prevention.

Pathophysiology[edit]

The syndrome develops through several overlapping mechanisms.

The combination of infection, inflammation, coagulation activation, adrenal bleeding, and cortisol deficiency creates a rapidly worsening shock state.

Signs and symptoms[edit]

Symptoms often begin nonspecifically and then progress quickly.

Early symptoms[edit]

Severe symptoms[edit]

Features of adrenal crisis[edit]

Not every patient has the full classic picture. Absence of meningitis, absence of extreme leukocytosis, or initially subtle rash does not exclude WFS.

Diagnosis[edit]

Diagnosis is clinical and should not delay treatment. Waterhouse–Friderichsen syndrome should be suspected in a patient with sepsis, shock, purpura, DIC, and signs of adrenal insufficiency, especially when meningococcemia is possible.

Emergency evaluation[edit]

  • Vital signs - Blood pressure, pulse, respiratory rate, oxygen saturation, temperature.
  • Sepsis evaluation - Rapid assessment for infection and organ dysfunction.
  • Blood culture - Should be obtained promptly if possible before antibiotics, but antibiotics should not be delayed.
  • Complete blood count - May show leukocytosis, leukopenia, anemia, or thrombocytopenia.
  • Comprehensive metabolic panel - Evaluates sodium, potassium, glucose, kidney function, and liver function.
  • Serum cortisol - May support diagnosis but should not delay hydrocortisone in adrenal crisis.
  • Adrenocorticotropic hormone - Can help distinguish primary adrenal failure when collected before steroids, if feasible.
  • Coagulation studies - PT, INR, aPTT, fibrinogen, and D-dimer evaluate DIC.
  • Lactate - Marker of shock and tissue hypoperfusion.
  • Arterial blood gas or venous blood gas - Assesses acidosis and respiratory status.
  • C-reactive protein and procalcitonin - May support infection assessment but are not definitive.
  • Urinalysis - Evaluates kidney and infection clues.
  • Lumbar puncture - May be performed when meningitis is suspected and patient is stable, but should not delay antibiotics.
  • Skin lesion culture or microscopy - May identify meningococci in purpuric lesions in some cases.

Imaging[edit]

Imaging may confirm adrenal hemorrhage but must not delay resuscitation in unstable patients.

A 2022 imaging review described urgent CT as a key diagnostic test when adrenal hemorrhage is suspected, while recognizing that unstable patients require immediate clinical treatment."Multimodality Imaging Findings in Waterhouse-Friderichsen Syndrome".Journal of Imaging.2022;8(12)

330.doi:10.3390/jimaging8120330.

Microbiologic diagnosis[edit]

Differential diagnosis[edit]

Treatment[edit]

Treatment must begin immediately when WFS or fulminant meningococcemia is suspected. Management occurs in an emergency department or intensive care unit.

Immediate management[edit]

CDC clinical guidance states that suspected meningococcal disease requires prompt antibiotics and that empiric therapy should include an extended-spectrum cephalosporin such as cefotaxime or ceftriaxone.Clinical Guidance for Meningococcal Disease(link). Centers for Disease Control and Prevention.

Adrenal crisis treatment[edit]

When adrenal crisis is suspected, hydrocortisone should be given immediately rather than waiting for confirmatory testing.

  • Hydrocortisone - Emergency glucocorticoid replacement.
  • Stress dose - High-dose glucocorticoid dosing used during severe illness.
  • Normal saline - Fluid resuscitation for hypotension and volume depletion.
  • Dextrose - Used when hypoglycemia is present or likely.
  • Fludrocortisone - Usually not needed acutely when high-dose hydrocortisone is used, but may be needed later in primary adrenal insufficiency.
  • Cortisol testing - Draw blood before steroid only if it does not delay treatment.
  • ACTH stimulation test - May be performed later when the patient is stable.

Emergency adrenal insufficiency guidance recommends prompt hydrocortisone for suspected adrenal crisis, commonly 100 mg intravenously or intramuscularly followed by ongoing hydrocortisone dosing."Guidance for the prevention and emergency management of adult patients with adrenal insufficiency".Clinical Medicine.2020;PMC:7385786.Primary Adrenal Insufficiency Guideline Resources(link). Endocrine Society.

Antibiotic therapy[edit]

Antibiotic choice depends on suspected source, age, local resistance, immune status, and culture results.

  • Ceftriaxone - Common empiric treatment for suspected meningococcal disease.
  • Cefotaxime - Alternative extended-spectrum cephalosporin.
  • Vancomycin - Added when resistant gram-positive infection or bacterial meningitis differential requires it.
  • Ampicillin - Added in some meningitis regimens when Listeria monocytogenes is a concern.
  • Meropenem - Used in selected severe sepsis or resistant organism concerns.
  • Penicillin G - May be used for susceptible meningococcal disease after confirmation.
  • Antimicrobial susceptibility testing - Helps narrow treatment.
  • Source control - Drainage or surgery may be needed for abscess or infected tissue.

Management of DIC and purpura fulminans[edit]

Supportive and long-term care[edit]

Prevention[edit]

Prevention focuses on reducing invasive meningococcal disease and preventing severe infection in high-risk groups.

Meningococcal vaccination[edit]

CDC provides current recommendations for meningococcal vaccination by age and risk group, including adolescents and people with increased risk such as asplenia, complement deficiency, or complement inhibitor therapy.Meningococcal Vaccine Recommendations(link). Centers for Disease Control and Prevention.

Chemoprophylaxis for contacts[edit]

Close contacts of invasive meningococcal disease patients require prompt antibiotic prophylaxis.

  • Rifampin
  • Ciprofloxacin
  • Ceftriaxone
  • Azithromycin in selected resistance situations
  • Household contacts
  • Childcare contacts
  • Direct exposure to oral secretions
  • Healthcare exposure during airway management without proper protection

CDC recommends antibiotic prophylaxis for close contacts of meningococcal disease patients, ideally as soon as possible after exposure.Public Health Strategies for Antibiotic-resistant Neisseria meningitidis(link). Centers for Disease Control and Prevention.Meningococcal Disease(link). CDC Yellow Book, NCBI Bookshelf.

General prevention of severe infection[edit]

  • Sepsis awareness
  • Early treatment of fever and rash
  • Vaccination against encapsulated bacteria in asplenia
  • Prompt care for immunocompromised patients
  • Safe anticoagulant monitoring
  • Infection prevention in healthcare settings
  • Patient education for complement inhibitor recipients
  • Medical alert identification for adrenal insufficiency when present

Complications[edit]

Prognosis[edit]

The prognosis depends on the cause, speed of recognition, timing of antibiotics, severity of shock, degree of adrenal destruction, extent of DIC, and presence of multi-organ failure. Fulminant meningococcemia with WFS can be fatal within hours if not recognized and treated quickly.

  • Early antibiotics improve survival in meningococcal disease.
  • Hydrocortisone can be lifesaving when adrenal crisis contributes to shock.
  • Severe purpura fulminans increases risk of amputation and death.
  • Survivors may require rehabilitation after critical illness, skin necrosis, or limb loss.
  • Long-term adrenal function should be reassessed after recovery.
  • Some patients may require temporary or permanent glucocorticoid and mineralocorticoid replacement.

Epidemiology[edit]

Waterhouse–Friderichsen syndrome is rare. It is most often described as a complication of fulminant meningococcal sepsis but has been reported with many other pathogens and noninfectious conditions. Its frequency has decreased in settings with effective meningococcal vaccination, rapid antibiotics, and improved intensive care, but it remains a critical emergency because of its rapid progression and high mortality.

  • Children and adolescents can be affected by meningococcal WFS.
  • Adults can develop WFS from meningococcal or nonmeningococcal sepsis.
  • Asplenic and complement-deficient patients are at increased risk for invasive meningococcal disease.
  • Complement inhibitor recipients are at markedly increased risk of meningococcal disease.
  • WFS may be underrecognized in noninfectious bilateral adrenal hemorrhage.

History[edit]

Waterhouse–Friderichsen syndrome is named for Rupert Waterhouse, an English physician, and Carl Friderichsen, a Danish pediatrician, who described cases of adrenal hemorrhage associated with severe infection in the early 20th century. Earlier descriptions of adrenal apoplexy also existed before the eponym became widely used.

Patient education[edit]

Waterhouse–Friderichsen syndrome is not a condition that can be managed at home. It is an emergency requiring hospital and intensive care treatment.

  • Fever with a rapidly spreading purple rash is an emergency.
  • Confusion, fainting, low blood pressure, or cold extremities with fever requires urgent care.
  • Meningococcal disease can progress very rapidly.
  • Vaccination reduces risk of meningococcal disease.
  • Close contacts of meningococcal disease patients may need preventive antibiotics.
  • People without a spleen should stay current on vaccines.
  • People taking complement inhibitors should understand their meningococcal risk.
  • Survivors may need endocrine follow-up for adrenal function.
  • Medical alert identification may be needed if long-term adrenal insufficiency remains.

When to seek emergency care[edit]

Immediate emergency care is required for symptoms suggesting meningococcemia, sepsis, or adrenal crisis.

  • Fever with petechiae or purpura
  • Fever with severe weakness or collapse
  • Hypotension
  • Confusion
  • Coma
  • Severe headache with fever
  • Neck stiffness with fever
  • Seizure
  • Rapid breathing
  • Cold, blue, or mottled extremities
  • Severe abdominal or back pain with shock
  • Repeated vomiting with weakness
  • Signs of septic shock
  • Known adrenal insufficiency with severe illness
  • Recent close exposure to meningococcal disease
