Atherosclerotic Risk Factors in Children with Celiac Disease.

Results: We found significantly lower concentrations of total cholesterol, lipoprotein LDL-C, apolipoproteins A1 and B, as well as hCRP in all children with CD. We showed decreased level (<5 ng/mL) of folic acid among 46% of children treated for >5 years. Moreover, we showed significant decrease of folic acid level already after 1 year of a GFD (12 .

Complications after primary bladder exstrophy closure - role of pelvic osteotomy.

Introduction: Bladder exstrophy is the most common form of the exstrophy - epispadias complex. It is observed in 1:30 000 life births, about four times more often in boys than in girls. Iliac osteotomy is used to facilitate bringing together pubic bones and to minimize the tension of fused elements.

Oxidative stress in hypertensive children before and after 1 year of antihypertensive therapy.

Background: The relation between primary hypertension (PH), target organ damage (TOD) and oxidative stress (SOX) is not known.

Methods: We assessed SOX in 86 children with PH before and after 12 months of standard non-pharmacological and pharmacological therapy based on renin-angiotensin system blockade.

Results: Patients with left ventricular hypertrophy (LVH) and with carotid intima-media thickness (cIMT) >2SDS had higher thiobarbituric acid reactive substances (TBARS) concentrations in comparison to patients without LVH or with normal cIMT.

Change in left ventricular geometry during antihypertensive treatment in children with primary hypertension.

The pattern of the left ventricle (LV) has important significance in adults with hypertension. The aim of the present study was to analyze changes and determinants of LV geometry after 1 year of antihypertensive treatment in children with primary hypertension (PH) in relation to metabolic abnormalities and anthropometrical parameters. In 86 children (14.

Regression of target organ damage in children and adolescents with primary hypertension.

We assessed the effects of 12 months of non-pharmacological and pharmacological therapy on 24-h ambulatory blood pressure, regression of target organ damage (TOD) and metabolic abnormalities in 86 children (14.1 ± 2.4 years) with primary hypertension.

Inflammatory activation in children with primary hypertension.

Low-grade inflammation plays a role in the pathogenesis of primary hypertension (PH) and target organ damage (TOD). We evaluated the profile of inflammatory mediators (CRP, RANTES, MIP-1beta, MIP-1alpha, MCP-1, IL-6, angiogenin, adiponectin) in 30 healthy children (12.7 +/- 3.

Evolution of large-vessel arteriopathy in paediatric patients with chronic kidney disease.

Unlabelled: This observational study was designed to verify the hypothesis that the treatment modality significantly affects the evolution of CKD-associated arteriopathy.

Patients: Paediatric patients (mean age 13.8 +/- 4.

Different BMI cardiovascular risk thresholds as markers of organ damage and metabolic syndrome in primary hypertension.

Obesity is the main intermediate phenotype of primary hypertension (PH), and increased fat mass is directly related to target organ damage (TOD) and metabolic syndrome (MS). The aim of the study was to assess the sensitivity and specificity of body mass index (BMI), percentile-based, definitions of obesity [BMI > 95th percentile (pc)], and overweight (BMI > 85th pc), and BMI thresholds for cardiovascular (cv) complications (BMIcv) described by Katzmarzyk et al. (Pediatrics 114:198-205, 2004) in predicting risk of TOD and MS in 122 adolescents with PH.

Metabolic abnormalities, insulin resistance, and metabolic syndrome in children with primary hypertension.

Background: We sought to describe the prevalence of metabolic abnormalities and of metabolic syndrome (MS) and its relationship to target-organ damage in children with primary hypertension (PH).

Methods: Patients included 113 children with untreated PH at a mean age of 14.6 years (range, 5 to 18 years).

[Oxidative stress and hypertensive arteriopathy in children with primary hypertension--preliminary results].

Unlabelled: Hypertensive arteriopathy and intima-media (IMT) thickening is observed already in adolescents with primary hypertension (PH) at diagnosis. The injury of arterial wall may cause also generation of free radicals and free radicals may by itself perpetuate arterial wall injury. The aim of the study was to verify the hypothesis that children with PH are exposed to oxidative injury (Sox) due to impaired antioxidant barrier, and that markers of Sox correlate with IMT and metabolic risk factors of arteriosclerosis.

[Target organ damage in children with newly diagnosed and untreated essential hypertension].

Unlabelled: Target organ damage in the course of essential hypertension (EH) may develop already in childhood. The aim of the study was to determine the prevalence of left ventricular hypertrophy (LVH) and arterial damage and its main determinants in children with newly diagnosed, untreated EH. PATIENTS (pts): 87 children (22 girls and 65 boys) with EH, age 14.

[Fat tissue distribution and metabolic alterations in boys with primary hypertension].

Unlabelled: Metabolic alterations related to obesity are regarded as significant risk factor for target organ damage in hypertensive patients. Fat tissue distribution seems to play significant role in metabolic alterations related to cardiovascular damage. The aim of the study was to test hypothesis that fat tissue distribution and excess of visceral fat is related to cardiovascular damage and metabolic cardiovascular risk factors in obese boys with yet untreated, primary hypertension.

Left ventricular hypertrophy and arterial wall thickening in children with essential hypertension.

Objective: Our aim was to determine the prevalence of left ventricular hypertrophy (LVH) and increased intima-media thickness (IMT) in Caucasian children with newly diagnosed, untreated essential hypertension (EH).

Participants: Our study cohort consisted of 72 children with EH (mean age: 14.5 years; range: 5-18 years).

Altered morphologic properties of large arteries in children with chronic renal failure and after renal transplantation.

Increased intima-media thickness of the carotid arteries (cIMT) has been found in young adults with childhood-onset chronic kidney disease (CKD). The disease stage at which these patients first develop abnormalities of arterial texture is unknown. The objective of this study was to determine the onset and character of arterial changes in children aged 10 to 20 yr with different stages of CKD and to identify risk factors for early arteriopathy.

Intima-media thickness and arterial elasticity in hypertensive children: controlled study.

The objective of this cross-sectional controlled study was to evaluate the intima-media thickness (IMT) of the common carotid artery (cIMT) and superficial femoral artery (fIMT), as well as the elastic properties of the common carotid artery, in children with essential arterial hypertension. The study included 49 children with newly detected essential hypertension [mean age 14.5 (range 6-20) years] and 61 healthy normotensive children [mean age 13.

In vivo effect of 5- and 8-methoxypsoralens and cimetidine on R,S-warfarin metabolism in rat.

Several forms of cytochrome P-450 (CYP) metabolize R,S-warfarin in a regio- and enantioselective manner, therefore R,S-warfarin can be recognized as a metabolic probe for a number of CYP isoforms. We have applied a warfarin model in vivo in order to estimate the inhibitory properties of 5- and 8-methoxypsoralens on the activity of rat CYP isoforms. The area under the serum concentration versus time curve (AUC) values from time zero to 5 h for R- and S-warfarin and their metabolites were calculated.
