Sabaz MN, Akin A, Bilici M, Demir F, Türe M, Balik H. Factors affecting mortality in children with dilated cardiomyopathy. Turk J Pediatr 2019; 61: 485-492. Dilated cardiomyopathy (DCMP) is a heart disease with high mortality rates that is often seen in children. Genetic and infectious reasons are primary in the etiology. The aim of this study was to investigate the etiology of DCMP and the parameters predicting mortality. A retrospective examination was made of 37 patients diagnosed with DCMP between January 2012 and October 2016. Data were recorded from the patient files of age, gender, complaints on presentation, findings of the physical examination, laboratory test results, echocardiography and electrocardiography findings at the time of diagnosis. These parameters were then compared between the surviving and nonsurviving patients. The patients comprised 21 males with a mean age of 27.50±50 months. Diagnosis was made at the age of < 12 months in 67.6% patients. Within mean 8 months of diagnosis, 16.2% of the patients were lost to mortality and 83.8% of the patients survived. In 83.3% of the non-surviving patients and in 29% of the surviving patients, sinus tachycardia was present at the time of diagnosis (p=0.023). Corrected QT (QTc) at the time of diagnosis was longer in the non-surviving patients (p=0.007). On ECG, the rate of ST-T wave change was higher in the non-surviving patients (80% vs. 17.8%, p=0.012). In conclusion, a significant proportion of the patients were diagnosed below the age of one year. In the non-surviving patients, as sinus tachycardia and ischaemic changes on ECG were seen more often and the QTc was longer, these findings could be considered to be predictors of mortality.

BACKGROUND: Familial Mediterranean fever (FMF) is an inflammatory disease, which is suggested to be associated with increased risk of atherosclerosis. Epicardial adipose tissue (EAT) thickness and the mean platelet volume (MPV) are parameters used in prediction of atherosclerotic risk in various conditions. These parameters were evaluated in children with FMF and compared with healthy controls. METHODS: Forty-five patients with FMF and 54 age- and gender-matched healthy controls were assessed. Duration of symptoms, age at diagnosis, duration of delay in diagnosis, frequency and duration of FMF attacks, disease severity scores, response to colchicine therapy, MEditerraneanFeVer (MEFV) gene mutations, and MPV values were recorded. EAT thicknesses were measured by echocardiography. RESULTS: Epicardial adipose tissue thicknesses of the children with FMF were found to be significantly greater than that of controls (5.1 ± 1.4 vs. 4.5 ± 0.9 mm, p=0.036). FMF patients had significantly higher MPV values compared with the controls (7.8 ± 1.1 vs. 7.3 ± 1.4 fl, p=0.044). Age at diagnosis, duration of delay in diagnosis, and MPV values were found to be correlated with EAT thickness in the patient group (r=0.49, p=0.001 for the former parameters and r=0.32, p=0.04 for MPV). CONCLUSION: Epicardial adipose tissue thickness and MPV values seem to be increased in children with FMF. These findings may indicate an increased risk of atherosclerosis in FMF patients.
