RESUMO
BACKGROUND: Familial Mediterranean fever (FMF) is an autoimmune disease with periodic fever attacks recurring with mutations in the MEFV gene and chronic inflammation. The new molecule which is formed as a result of the chemical changes made by oxidative free radicals in the albumin molecule during ischemic events is called ischemia modified albumin (IMA). AIM: The aim of this study is to evaluate the IMA levels as a predictor of the cardiovascular risk factor in FMF patients in the attack-free period and to evaluate the relationship between IMA and inflammation markers. METHODS: Forty FMF patients without any additional disease, non-smokers, and in their attacks-free period, 40 ankylosing spondylitis patients whose disease activity criteria is less than 4 from Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and 39 healthy adults were included in the cross-sectional analytical research. RESULTS: The value of IMA was statistically significantly higher in the AS group compared to the control group (p = 0.01). The positive correlations between IMA and ESR, LDL, total cholesterol, triglyceride, CRP, and fibrinogen were statistically significantly determined in FMF patients (respectively; r = 0.594; p < 0.001, r = 0.382; p = 0.015, r = 0.335; p = 0.034, r = 0.363; p = 0.021, r = 0.597; p < 0.001, r = 0.656; p < 0.001). The positive correlations between IMA and ESR, CRP were found in AS patients (respectively; r = 0.383; p = 0.015, r = 0.382; p = 0.015). CONCLUSION: IMA can be used as a predictor similar to cardiovascular risk factors and it is a precious marker for inflammation. The use of IMA in these fields and the multi-centred and comparative studies about predictability of it may contribute to science.
