BACKGROUND Familial Mediterranean fever (FMF) is an autosomal recessive disease mainly affecting particularly Arabs, Non-Ashkenazi Jews, Armenians, and Turks. It is an autoinflammatory periodic disorder characterized by febrile and painful attacks due to inflammation involving the serosal membranes in the abdomen, chest or joints. Over 50 mutations have been identified in the MEFV gene responsi...

Certain vasculitides have an increased prevalence among patients with familial Mediterranean fever (FMF). Subsequently, it was noticed that patients with certain rheumatic diseases had an increased carrier rate for mutations in the MEFV gene including seronegative spondyloarhtropatheis, Henoch Schönlein purpura, polyarteritis nodosa and some forms of juvenile idiopathic arthritis. Furthermore i...

In their otherwise excellent review of familial Mediterranean fever (FMF), Lidar and Livneh argue against testing for Mediterranean fever gene (MEFV) mutations both in their diagnostic algorithm and in their subsequent discussion of the case. Although the clinical criteria for FMF are highly sensitive and specific, incorporation of genetic testing will not only confirm the diagnosis but adds va...

Methods Files of patients who had been seen in our department (during routine follow-up visits) between January 2013 and January 2014 were retrospectively evaluated. Six predominant mutations (p.M694V, p.M680I, p.M694I, p.V726A, p.K695R, p.E148Q) in the MEFV gene were studied in our center. Patients were divided into two groups: group I included patients with heterozygous mutations and group II...

Sweet’s syndrome (SS) or acute febrile neutrophilic dermatosis is a rare disorder that often occurs in association with other systemic diseases. The disorder is characterized by development of nonpruritic, painful erythematous plaques with pseudovesicles, occasional pustules and rare bullae. SS consists of a triad of erythematous plaques infiltrated by neutrophils in association with fever and ...

OBJECTIVES To identify the frequency and distribution of familial Mediterranean fever (FMF) gene (MEFV) mutations among Azeri Turkish patients from northwestern Iran. METHODS One hundred ninety unrelated patients were referred by specialists to the Molecular-Medical Genetic Center of Tabriz. A clinical diagnosis of FMF was made according to published criteria. Mutation screening of the MEFV g...

Background Familial Mediterranean Fever (FMF) is an autosomalrecessive disorder characterized by recurrent attacks of fever and serositis. It is common in eastern Mediterranean population. There are only few FMF patients in Slovenia and Macedonia and the mutation carrier rate is not known. So far, over 80 disease associated mutations have been identified in MEFV gene; the most common are M694V,...

We report on a familial Mediterranean fever (FMF) patient homozygous for p.M694V in the MEFV gene who developed chronic myelomonocytic leukemia (CMML) leading to an uncontrolled and fatal inflammatory syndrome. Plasma levels of IL-6 and IL-18 were found to be very high, as compared to healthy controls and CMML-free FMF patients.Our study unveils the interplay between two different disorders inv...

Introduction PFAPA syndrome (acronym for periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) is the most common cause of periodic fever in childhood. It is considered part of the wide family of the autoinflammatory diseases, but a genetic or molecular marker hasn’t been identified yet, therefore, its etiology is still unknown. Diagnosis is essentially based on clinical crite...
