Background Childhood acute lymphoblastic leukaemia (ALL) survivors have an increased risk of metabolic and cardiovascular disease. We aimed to assess the presence of non-alcoholic fatty liver disease (NAFLD) in childhood ALL and if it is associated with early cardiovascular dysfunction. Methods In total, 53 childhood ALL survivors and 34 controls underwent auxological evaluation, biochemical assay, liver, heart and vascular ultrasound study. Results NAFLD was more frequent in ALL patients than in controls (39.6% vs 11.7%, P < 0.01). Patients with NAFLD were more obese and insulin resistant than patients without NAFLD. Flow-mediated dilatation and interventricular septum were lower in the ALL group than those in the control group (P < 0.001 for both). The patients with NAFLD showed lower left ventricular ejection fraction than those without NAFLD (P = 0.011). In ALL survivors, BMI-SDS and subcutaneous fat were the strongest predictors of NAFLD, whereas preperitoneal adipose tissue and C-reactive protein were the strongest predictors of left ventricular ejection fraction. Conclusions Childhood ALL survivors had higher prevalence of NAFLD than healthy controls, which is associated with early left ventricular impairment. In the case of fatty liver, a comprehensive heart evaluation is mandatory. We strongly recommend to prevent visceral adiposity in ALL survivors, to search for metabolic syndrome or its components and to reinforce the need of intervention on diet and lifestyle during the follow-up of these patients.

Background    Obese non-alcoholic fatty liver disease (NAFLD) was found to increase the risk of developing atrial fibrillation (AF) regardless of the metabolic syndrome subgroups that may accompany it. In this study, the effect of NAFLD on the structural and electrical functions of the heart was investigated using tissue Doppler echocardiography (TDE) in non-obese NAFLD patients without any known risk factors for AF.Material and methods    The study included 43 female patients (31.3±3.8 years), who had stage 2–3 hepatosteatosis detected by liver ultrasonography and diagnosed as non-obese NAFLD (patient group), and 31 healthy women (control group, 32.5±3.6 years). In addition to standard echocardiographic parameters, inter- and intra-atrial electromechanical delay (EMD) were evaluated by TDE.Results    Interatrial EMD (PA lateral – PA tricuspid) and intraatrial EMD (PA septum – PA tricuspid) were significantly longer in patient group (16.1±3.4 vs. 12.5±2.3 ms, p<0.001, and 8.4±1.6 vs. 6.6±1.6 ms, p<0.001, respectively). At the subclinical level. atrial size, left ventricular diastolic function, and left ventricular wall thickness measurements were greater in the patient group.Conclusion    Inter-atrial and intra-atrial EMD were detected in young women with non-obese NAFLD. In addition, at the subclinical level, structural and functional impairment was detected However, large-volume prospective studies are required to cobfirm these findings regarding the development of AF in non-obese NAFLD patients.

The research estimates the state of liver detoxifying function and analyzes the changes in the levels of leptin, adiponectin and interleukin-6 in patients with arterial hypertension in combination with obesity and non-alcoholic fatty liver disease. Aim. The aim of the study is to evaluate levels of proto-hormones adipose tissue, interleukin-6 and indicators of detoxifying function of the liver in patients with hypertension and obesity combined with non-alcoholic fatty liver disease (NAFLD). Materials and methods. The study involved patients with arterial hypertension combined with obesity and NAFLD. All patients underwent anthropometric, general clinical, laboratory (blood lipid profile) and instrumental diagnostics (electrocardiography, echocardiography, ultrasonography, 13C-metacetin breath test, ELISA (adiponectin, leptin, IL-6). The patients’ height and weight were measured, the body mass index was calculated according to standard formulas. Results. Patients with arterial hypertension combined with obesity and NAFLD at the stage of steatohepatitis showed an increase in the levels of leptin and IL-6 and a decrease in the level of adiponectin. This group also revealed a moderate decrease in liver detoxifying function, as indicated by the results of 13C- MBT due to a 46.7 % decrease in the metabolic rate and a decrease in cumulative doses of CUM40 by 40 % and CUM120 by 46.8 %, respectively. Conclusions. The elevated levels of leptin and IL-6 and lowered adiponectin levels can be used to determine the degree of activity of non-alcoholic steatohepatitis and predict the course of NAFLD in combination with hypertension and obesity. An increased level of leptin and IL-6 and a low level of adiponectin in patients with such a comorbid pathology lead to an increase in the left ventricular myocardial mass index and aggravate the course of arterial hypertension.

Abstract Objectives: To detect early left ventricular dysfunction in children with non-alcoholic fatty liver disease using three-dimensional speckle tracking echocardiography. Methods: Forty obese children with non-alcoholic fatty liver disease were included as group I. Another 40 obese children without non-alcoholic fatty liver disease of matched age, sex, and weight were included as group II. Forty healthy controls of matched age and sex served as a control group. Anthropometric measurements, laboratory investigations, and echocardiographic examinations including three-dimensional speckle tracking echocardiography were measured for all included children. Results: Abnormal lipid profile was detected in children with non-alcoholic fatty liver disease. Troponin I levels were significantly higher in children with non-alcoholic fatty liver disease compared to obese children without non-alcoholic fatty liver disease and to healthy controls. Three-dimensional speckle tracking echocardiography examination revealed a significant reduction of left ventricular global longitudinal strain, circumferential strain, radial strain, and area strain in children with non-alcoholic fatty liver disease inspite of normal left ventricular fraction shortening measured by conventional echocardiography. All strains were negatively correlated with the grade of non-alcoholic fatty liver disease. Conclusion: Non-alcoholic fatty liver disease is associated with subclinical left ventricular dysfunction. Three-dimensional speckle tracking echocardiography can be helpful in identifying early left ventricular dysfunction in children with non-alcoholic fatty liver disease even in the presence of normal left ventricular ejection fraction.

Abstract. Some epidemiological evidence suggests an inverse correlation between non-alcoholic fatty liver disease (NAFLD) frequency and vitamin D levels. Likewise, a beneficial effect of vitamin D on diabetes mellitus (DM) and insulin resistance has been observed, but this is an unsolved issue. Thus, we aimed to investigate the prevalence of hypovitaminosis D in a NAFLD Brazilian population and its association with disease severity and presence of comorbidities. In a cross-sectional study, the clinical, biochemical and histological parameters of 139 NAFLD patients were evaluated according to two different cut-off points of serum 25-hydroxyvitamin D levels (20 ng/mL and 30 ng/mL). The mean age of the population was 56 ± 16 years, most patients were female (83%), 72% had hypertension, 88% dyslipidemia, 46% DM, 98% central obesity, and 82% metabolic syndrome. Serum vitamin D levels were < 30 ng/mL in 78% of the patients, and < 20 ng/mL in 35%. The mean vitamin D level was 24.3 ± 6.8 ng/mL. The comparison between the clinical, biochemical and histological characteristics of the patients according to the levels of vitamin D showed no significant difference. Most patients with NAFLD had hypovitaminosis D, but low vitamin D levels were not related to disease severity and the presence of comorbidities.
