Familial Mediterranean Fever synonyms

Familial Mediterranean Fever (FMF) is an autoinflammatory disorder historically known as periodic disease or benign paroxysmal peritonitis. While older literature may use various terms, Familial Mediterranean Fever is the standard clinical name used in modern medical practice and international classification systems.

Why does Familial Mediterranean Fever have multiple names?

The naming of Familial Mediterranean Fever has evolved significantly since it was first described in the mid-20th century. Historically, physicians observed recurring episodes of fever and inflammation but did not yet understand the underlying genetic cause, leading to descriptive names based on clinical presentation. As medical science progressed and the MEFV gene was identified in 1997, the medical community moved toward the more precise term Familial Mediterranean Fever to reflect both the hereditary nature and the common geographic ancestry of affected populations.

What are the historical and alternative names for Familial Mediterranean Fever?

In older medical charts or research papers, you may encounter several synonyms. Recognizing these terms is helpful when reviewing historical family medical records or older clinical studies. Common alternative names include:

• Periodic disease: A broad term used before the pathophysiology was fully understood.


• Benign paroxysmal peritonitis: Refers to the recurring abdominal pain caused by inflammation of the peritoneum.


• Familial paroxysmal polyserositis: A more technical description reflecting the inflammation of multiple serous membranes (like the lining of the lungs or abdomen).


• Reimann’s syndrome: Named after Hobart Reimann, who categorized various periodic fevers in the 1940s.


• Wolff’s disease: An older eponym occasionally found in historical European literature.

How is Familial Mediterranean Fever classified in medical systems?

To ensure consistency in global healthcare, Familial Mediterranean Fever is categorized under specific codes in major medical databases. Using these codes can be essential for insurance claims and clinical documentation. Official classifications include:

1. Orphanet: Classified under ORPHA:342, identifying it as a rare genetic autoinflammatory disease.


2. OMIM (Online Mendelian Inheritance in Man): Listed as #249100, which confirms the autosomal recessive inheritance pattern.


3. ICD-10/11: Categorized under E85.0 (Hereditary amyloid nephropathy, which is a potential complication) or specific codes for periodic fever syndromes.

Which name should patients and providers use today?

Today, Familial Mediterranean Fever is the universally accepted terminology preferred by rheumatologists, geneticists, and researchers. Using this specific name ensures that your healthcare providers are accessing the most current clinical guidelines for treatment, such as the use of colchicine to prevent systemic amyloidosis. Within the DiseaseMaps.org community, where 264 individuals share their experiences, using the standard term Familial Mediterranean Fever helps connect patients with relevant clinical trials, support groups, and the latest research updates.
