Mediterranean Fever

Aim: Familial Mediterranian Fever is an autosomal recessive disease characterized by recurrent inflammatory attacks of serosal membranes. The aim of the current study was to determine the frequency of the Mediterranean fever (MEFV) gene pathogenic variants in 158 children (78 male, 80 female) diagnosed with Familial Mediterranean Fever (FMF) and to compare the phenotype-genotype correlation. Methods: In our retrospective case-control study, 158 FMF patients (78 males, 80 females) who were diagnosed with MEFV gene mutation in Bursa Yuksek Ihtisas Training and Research Hospital, Department of Pediatrics between January 2018 and June 2019 were included in the study.  Mutation screening of the MEFV gene was performed for 12 mutations and the 8 most common mutations were taken into the study. Results: Abdominal pain (77.8%), fever (74%) and arthralgia (46.2%) were the most prevalent clinical features in our patients. The most frequent mutations were M694V, E148Q, V726A, M680I and P369S. In cases with M694 mutation, it was noted that the incidence of arthritis was 2.5 times, appendectomy frequency 3.1 times higher, and early diagnosis probability 3.2 times higher. The frequency of chest pain was 2.9 times higher in the M680I mutation, and the frequency of arthralgia was 2.2 times higher in the P369S mutation. Conclusion: Patient’s mutations in FMF patients are important for clinical expectations, and some mutations such as P369S are not as innocent as expected. However, reevaluation of phenotypes of mutations that are rare with more patients will be significant.

Mediterranean Fever

Background. Familial Mediterranean Fever (FMF) is a hereditary autosomal recessive disease which is mainly seen in the Turks, Armenians, Arabs, and Jews. It is characterized by recurrent episodes of fever, polyserositis, and rash. MEFV gene, encoding pyrin protein, is located on the short arm of chromosome 16. FMF is associated with a broad mutational spectrum in this gene. Certain mutations are more common in particular ethnic groups. To date, different mutations of MEFV were observed in studies carried out in different regions worldwide. However, most of these studies did not extensively investigate the Egyptian population, in spite of the high prevalence of FMF in this geographical region. Aim. To identify the frequency of MEFV gene mutations among the patients who presented with FMF like symptoms and, to characterize the different genetic mutations and their association with increased Amyloid A among Egyptian patients. Methods. FMF Strip Assay (Vienna Lab Diagnostics, Vienna, Austria) was used. This test is based on reverse hybridization of biotinylated PCR products on immobilized oligonucleotides for mutations and controls in a parallel array of allele-specific oligonucleotides. Results. Among the 1387 patients presenting with signs and symptoms suggestive of FMF, 793 (57.2%) were of undefined mutations, whereas 594 had MEFV gene mutations. 363 patients (26.2%) were heterozygous mutants, 175 patients (12.6%) were compound heterozygous mutants, and 56 patients (4%) were homozygous mutants. The most commonly encountered gene mutations in heterozygous and homozygous groups were E148Q (38.6%), M694I (18.1%), and V726A (15.8%). The most commonly encountered gene mutations in the compound heterozygous groups were E148Q+M694I observed in 20.6% of the patients, followed by M694I+V726A and M6801+V726A found in 18.9% and 11.4 %, respectively. The most commonly encountered gene mutation associated with abdominal pain, fever, and high serum Amyloid A was E148Q allele (37.5%). Conclusions. Unlike all previous publications, E148Q allele was found to be the most frequent in the studied patients. Moreover, this allele was associated with increased Amyloid A. 793 patients were free of the 12 studied Mediterranean mutations, which implies the necessity to perform future sequencing studies to reveal other mutations.

Introduction. Familial Mediterranean fever (FMF) is an auto-inflammatory disease characterized by attacks of fever and polyserositis. FMF is often associated with other autoimmune diseases such as rheumatoid arthritis, polyarteritis nodosa (PAN), and Behcet. Uveitis is an inflammatory process caused by underlying infectious and inflammatory disorders. This study investigates the probable relationship between idiopathic uveitis and FMF.Methods. Patients with idiopathic uveitis were analyzed for the 12 most common MEFV mutations (P369S, F479L, M680I(G/C), M680I(G/A), I692del, M694V, M694I, K695R, V726A, A744S, R761H, E148Q) by a reverse hybridization assay (FMF StripAssay,Vienna lab,Vienna, Austria).Results. 12 patients with idiopathic uveitis were enrolled in this study. 10 of them were female. The youngest patient was a 7-year-old child and the oldest was 57. The most common complaints of patients were blurred vision and then eye redness. One patient was heterozygous for R761H. Genetic analysis of the 12 most common MEFV mutations in the patients with idiopathic uveitis didnot have any positive results.Conclusion. According to the analysis of the 12 most common MEFV gene mutations, FMF is not an underlying cause of idiopathic uveitis. On the other hand, uveitis merely could not be the first presentation of FMF.
