Abstract

It is well established that there are people with higher risk of developing acute rheumatic fever (ARF) and rheumatic heart disease (RHD). Mediterranean fever (MEFV) gene mutations might be one of the genetic predisposition factors in the development of ARF/RHD since defect in familial Mediterranean fever (FMF) patients is proposed to be heightened inflammatory response to certain stimuli. Previous clinical observations suggested a relationship between FMF and ARF/RHD. The aim of this study was to investigate the role of the MEFV gene mutations in the susceptibility to RHD in Turkish patients. A total of 100 patients with RHD and 100 healthy controls were included in the study. Diagnosis of RHD was based on echocardiographic findings in which a predominant mitral stenosis was used as an inclusion criterion. Genetic analysis was carried out by sequence analysis investigating two hot spots (exons 2 and 10) for MEFV mutations. Mutation analysis showed that 22 RHD patients (22%) and 24 healthy controls (24%) carried at least one mutated allele. MEFV mutations were identified in 22 of 200 (11%) chromosomes in RHD patients while 26 of the 200 (13%) chromosomes of healthy controls were found to carry a mutated allele. No difference wa...Continue Reading
