The relation of novel cardiovascular risk parameters in patients with familial Mediterranean fever.

OBJECTIVE: In this study, we aimed at correlating the thickness of epicardial adipose tissue and levels of Vitamin D with cardiac risk in patients with familial Mediterranean fever. METHODS: Sixty-five patients with familial Mediterranean fever and 38 healthy controls with matching age and sex were included in the study. The patients with a history of familial Mediterranean fever attacks within the previous two weeks or with any history of inflammatory or cardiovascular disease were excluded. Data regarding age, gender, weight, height, waist circumference, body mass index (calculated as weight/height2), pulse wave velocity, serum Vitamin D levels from fasting blood samples, and Homeostatic Model Assessment for insulin resistance were obtained for the patients and controls. The epicardial adipose tissue was visualized as an echo-free space between the outer surface of myocardium and visceral pericardium using two-dimensional echocardiography, and the thickness of epicardial adipose tissue was measured in parasternal long-axis view at the end of diastole. RESULTS: The patients with familial Mediterranean fever had significantly higher levels of C-reactive protein, epicardial adipose tissue, and pulse wave velocity (p < 0.001, <0.05, <0.005, respectively) as compared with the control group. However, the serum Vitamin D levels in the two groups were observed to be similar (p = 0.486). Weak but significant positive correlations were observed between epicardial adipose tissue thickness and C-reactive protein (r = 0.302, p < 0.005), epicardial adipose tissue thickness and pulse wave velocity (r = 0.263, p < 0.01), and C-reactive protein and pulse wave velocity (r = 0.235, p < 0.05). CONCLUSION: Thickness of epicardial adipose tissue and pulse wave velocity were observed to increase in patients with familial Mediterranean fever.

Neutrophil-lymphocyte ratio in patients with familial Mediterranean fever.

BACKGROUND: Blood neutrophil-to-lymphocyte (N/L) ratio is an indicator of the overall inflammatory status of the body, and an alteration in N/L ratio may be found in patients with familial Mediterranean fever (FMF). The aim of this study was to investigate the interrelationship between N/L ratio and FMF. METHODS: One hundred and fifteen patients and controls were enrolled in the study. The cases in the study were categorized as FMF with attack, FMF with attack-free period, and controls. The neutrophil and lymphocyte counts were recorded, and the N/L ratio was calculated from these parameters. All patients were diagnosed according to Tel Hashomer criteria. RESULTS: A total of 79 FMF patients were included in the study and all subjects were receiving colchicine treatment at the time. The serum N/L ratios of active patients were significantly higher than those of attack-free FMF patients and controls (P < 0.001). The optimum N/L ratio cut-off point for active FMF was 2.63 with sensitivity, specificity, positive predictive value, and negative predictive value of 0.62 (0.41-0.80), 0.85 (0.72-0.93), 0.67 (0.44-0.85), and 0.82 (0.69-0.91), respectively. The overall accuracy of the N/L ratio in determination of FMF patients during attack was 71%. CONCLUSION: Our results demonstrate that N/L ratio is higher in patients with active FMF compared with FMF patients in remission and controls, and a cut-off value of 2.63 can be used to identify patients with active FMF.

Non-alcoholic fatty liver disease in patients with migraine.

Evidence suggests that migraine is associated with metabolic syndrome, which is also implicated in non-alcoholic fatty liver disease (NAFLD). Reported for the first time, we aimed to investigate the relationship between migraine and NAFLD in patients with migraine. A total of 90 consecutive migraine patients were enrolled in this cross-sectional study. The diagnosis of migraine was determined according to the International Classification of Headache Disorders-II diagnostic criteria. The diagnosis of NAFLD was based on abdominal ultrasonography findings. Anthropometric indices and the homeostasis model assessment of insulin resistance (HOMA-IR) were calculated, and serum insulin level measurements and other biochemical analyses were performed for each subject. The measurements of body mass index and waist circumference were significantly higher in migraine patients with NAFLD than in those without NAFLD (p < 0.001). Regarding the laboratory results, insulin (p = 0.024), alanine aminotransferase (p = 0.027), and triglyceride levels (p = 0.001) and the HOMA-IR (p = 0.039) were higher in migraineurs with NAFLD than in those without NAFLD. Among the headache characteristics, the presence of aura was higher, and disease and attack durations were significantly longer in migraineurs with NAFLD than in those without NAFLD (p = 0.005, p = 0.024, and p = 0.023; respectively). However, the headache characteristics did not correlate with either the hepatosteatosis grade or HOMA-IR in migraine patients (p > 0.05). Our results show that NAFLD may present in migraine patients with higher frequency of auras and longer disease and attack durations.
