P01-032 – Characterization of genetic-negative FMF
نویسندگان
چکیده
Methods In this observational comparative study, 47 sequential genetic negative FMF patients and 78 sequential genetic positive (for at least one allele) FMF control patients were compared using a comprehensive questionnaire completed at the time of their routine clinic visit, using direct questioning and patients’ files. The definition of FMF was based on our clinical tool, widely accepted for FMF diagnosis. Absence of the 5 most common MEFV mutations in routine genetic testing of FMF was considered genetic negative FMF. Disease severity was determined by Mor criteria.

Methods We observed 2300 patients with FMF (1408 boys and 892 girls; mean age: 8.86±0.29) in the National Pediatric Centre for FMF. Diagnosis of FMF was based on Tel-Hashomer criteria and MEFV genetic analysis. The epilepsy was diagnosed based on clinical manifestations (>2 unprovoked epileptic seizures),neurological history, exam, EEG and MRI. The statistical analysis was performed using Epi-I...
متن کاملPW01-032 – FMF-like state: genetic factors unrelated to MEFV
Introduction FMF is considered an autosomal recessive autoinflammatory syndrome caused by single gene (MEFV) mutations. Recently, it has been known that also heterozygous mutation carriers can suffer from a mild or incomplete form of FMF, named FMF-like disease. Among Armenians, who have relatively high carrier rate of MEFV mutations, single mutation has been detected in about 1/5 of symptomati...

Results At colchicine prescription, genetic results were not available for 229/681 patients (34%). A typical phenotype was significantly more common in this subgroup than in patients with genetic testing at prescription (212/229, 92%, vs. 260/452, 58%, OR=9.2 95% CI 5.4-15.6, p=0.0001). Of note, despite the high frequency of typical phenotype in this group, the rate of 2 pathogenic variants of ...
متن کاملFamilial Mediterranean fever without MEFV mutations: a case–control study
BACKGROUND Although familial Mediterranean fever (FMF) was originally defined as an autosomal recessive disorder, approximately 10-20% of FMF patients do not carry any FMF gene (MEFV) mutations. Fine phenotype characterization may facilitate the elucidation of the genetic background of the so called "FMF without MEFV mutations". In this study we clinically and demographically characterize this ...

Methods We studied consecutive FMF patients, who came for a pre-scheduled follow up visit in the FMF clinic for the presence of microscopic hematuria, defined as ≥5 RBC/HPF or ≥25RBC/μl in urine analysis performed during remission, recorded at least once in the 3 previous clinic visits. Exclusions were known kidney, urinary tract, prostate or gynecologic diseases, bleeding or thrombotic diathes...
