Background: Systemic-onset Juvenile Idiopathic Arthritis (SoJIA) is an autoinflammatory disease with complex genetic trait starts in children less than 16 years of age with fever and cutaneous rash. Despite, the main genetic factors that may play a role in SoJIA have not yet been identified. High level of interleukin-1beta in the blood of SoJIA patients has been reported. The production and sec...

Background and objectives: Behcet's Disease (BD) is a rare severe recurrent inflammatory disorder affecting several body organs. Since Familial Mediterranean Fever (FMF) and BD affect almost a specific population, both diseases can mimic the other clinically, and these two diseases sometimes occur in the same family and the same patient, also due to the high prevalence of BD in Iran and perform...

BACKGROUND Due to an increased frequency of vasculitis in FMF patients, many investigators have studied MEFV mutations in patients with HSP. The aim of the study is to investigate the frequency and clinical significance of MEFV mutations in Egyptian children with Henoch-Schonlein purpura (HSP). Investigating MEFV mutations in controls may help in estimating the prevalence of MEFV mutation carri...

BACKGROUND/AIM To define the frequency of familial Mediterranean fever gene (MEFV) mutations in ankylosing spondylitis (AS) and describe different clinical aspects of MEFV mutation carrier and noncarrier AS patients. MATERIALS AND METHODS In 112 AS patients, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) scores were calcula...

Methods 113 caucasian patients carrying MEFV mutations (46 with mutations in two alleles, 67 heterozygous) and 205 genetically negative patients for MEFV, TNFSF1A and MEFV (70% with a PFAPA phenotype) were analyzed. The following groups were considerd: patients with: i) 2 high penetrance mutations (M694V, M694I, M680I), ii) 1 high, 1 low penetrance mutation, iii) 2 low penetrance mutations, iv)...

objective(s):familial mediterranean fever (fmf) is an autosomal recessive disorder characterized by recurrent episodes of fever accompanied by peritonitis, pleurisy, and arthritis. fmf affects mainly mediterranean populations and is caused by mutations in the familial mediterranean fever (mefv) gene. the aim of this study was to identify the frequency and distribution of mefv mutations in irani...

BACKGROUND Pyrin is a newly recognised intracellular regulator of inflammation, and mutations in MEFV, the gene encoding pyrin, are the cause of familial Mediterranean fever. OBJECTIVE To determine if known mutations of MEFV are associated with rheumatoid arthritis (RA) morbidity or can modify RA severity. METHODS The frequency of the three most common MEFV mutations: M694V, V726A, and E148...
