Living with Corticosteroid-sensitive aseptic abscess syndrome

A rare condition of the immune system with repeated fevers and abscesses that have no infection.

Understanding Corticosteroid-sensitive aseptic abscess syndrome

Corticosteroid-sensitive aseptic abscess syndrome is a rare autoinflammatory disorder with repeated attacks of fever and sterile abscesses (pus pockets with no germs).

Autoinflammatory means the body's immune system causes inflammation on its own. The condition often starts in the teen years or adulthood. It can involve the liver, lymph nodes, and other organs.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Fever
  • Abdominal pain
  • Liver abscess
  • Weight loss
  • Anemia
  • High neutrophil (white cell) count

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
