Case report An 8-year-old female presented with episodes of fever, abdominal pain, vomiting, and arthralgia lasting 3-5 days for 1-year duration suggestive of FMF. Atypical FMF features included longer episodes of fever and partial response to colchicine. Family history revealed HIDS in an 18 years old brother. He presented with episodes of fever, abdominal pain, vomiting, diarrhea, skin rash, ...

Familial Mediterranean fever (FMF) is an autosomal recessive disorder primarily affecting the Mediterranean populations. It is characterized by recurrent attacks of fever and inflammation of serosal membranes and gradual development of nephropathic amyloidosis. More than 70 disease-associated mutations have been identified in the Mediterranean fever gene (MEFV) responsible for FMF. The aim of t...

Results IL-1b, IL-6, IL-8, TNF-a, and IFN-g were not increased in either type of FMF in the remission state and in controls, and IL-6 was elevated during attack periods among patients. Serum IL-18 levels were significantly higher in typical FMF patients with M694I MEFV mutation in remission than in controls at the same level as flared Kawasaki disease, which further increased during attack peri...

BACKGROUND Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent attacks of fever with serosal inflammation. FMF gene (MEFV) mutations have been identified primarily in patients from Mediterranean populations. Although several clinical cases have been reported in Japan, there have been few reports to date on mutation analysis. We studied FMF patients an...

Background Systemic autoinflammatory diseases (SAIDs) are a group of diseases characterized by episodes of inflammation, usually manifested with fever and a variety of symptoms, including skin-rash, arthritis and abdominal pain. A clinical overlap between different SAIDs, may cause diagnosis uncertainty. Familial Mediterranean fever (FMF), the prototype of the autoinflammatory syndrome, is mani...

Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disease with autosomal recessive inheritance pattern often seen around the Mediterranean Sea. It is characterized by recurrent episodes of fever and polyserositis and rash. Recently, MEFV gene analysis determines the definitive diagnosis of FMF. In this study, we analyzed 12 MEFV gene mutations in more than 200 FMF patients, pr...

BACKGROUND The Mediterranean fever (MEFV) gene codes for protein pyrin, one of the regulators of inflammasome activity in innate immune cells. Mutations in this gene are considered the primary cause of Familial Mediterranean fever, but are also found in other monogenic and multifactorial autoinflammatory diseases. The aim of the study was to determine if healthy carriers of MEFV gene mutations ...

Purpose: Familial Mediterranean Fever (FMF) is a hereditary auto inflammatory disease (MIM#249100). The most common symptoms are high fever, abdominal pain and arthralgia. FMF the result of variations in MEditerraneanFeVer (MEFV) gene, which located on chromosome 16p13.3, consists 10 exons encodes pyrin (marenostrin) protein. frequency MEFV gene variants that cause varies according to ethnic gr...

BACKGROUND Familial Mediterranean fever (FMF) is the most common autoinflammatory disorder in the world. It is characterized by recurrent febrile inflammatory attacks of serosal and synovial membranes. MEFV gene mutations are responsible for the disease and its protein product, pyrin or marenostrin, plays an essential role in the regulation of the inflammatory reactions. Although the disease ma...
