PREDICTORS OF CAROTID INTIMA MEDIA THICKNESS IN OBESE ADOLESCENTS

Our aim was to assess cardiovascular risk factors that may predict increased carotid intima media thickness (cIMT) in obese children and adolescents. Children and adolescents were included in the cross-sectional study if they were aged 9-19 years and had primary obesity. Besides anthropometric and biochemical measurements, ambulatory blood pressure monitoring, measurement of carotid intima media thickness and exercise stress test were performed. We included 103 obese patients and divided them according to the ambulatory blood pressure findings in two groups: obese patients with and without ambulatory hypertension. There were 49 obese patients with and 54 without ambulatory hypertension Univariate analysis showed that there was a significant positive correlation of cIMT with age (r = 0.334, p= 0.001), body mass index (r = 0.288, p = 0.004), waist circumference (r = 0.352, p = 0.000), hip circumference (r = 0.288, p = 0.004), night-time systolic blood pressure (r = 0.226, p = 0.027), and peak diastolic blood pressure on exercise test (r = 0.241, p = 0.018). In a stepwise model, age, waist circumference and peak diastolic blood pressure on exercise test were independent predictors of cIMT

CALCIURIA IN CHILDREN WITH PRIMARY MONO-SYMPTOMATIC NOCTURNAL ENURESIS

Introduction: The prevalence of idiopathic hypercalciuria (IH) in healthy pediatric population ranges from 3.0% to 7.0%. There is insufficient data about IH in children with mono-symptomatic enuresis. The aim of this study was to examine calcium excretion in urine (UCa) in patients with primary mono-symptomatic nocturnal enuresis (PMNE). Methods: In patients with PMNE, aged 5 to 17 years, IH was determined in 24-h urine and from second morning spot urine. The completeness of the 24-h urine collections was estimated via measuring 24h-urine creatinine excretion (UCr) of 0.1–0.2 mmol/kg/24h. Results: Sixty patients with PMNE, 32 males and 28 girls, median age of 9 years were enrolled in the study. Only 41.7% patients successfully completed 24 h urine collection. IH, defined as 24-h UCa >0.1 mmol/kg body weight, was diagnosed in 12% of the patients, while when defined as UCa/UCr >0.8 mmol/mmol in children 5-7 years and >0.6 mmol/mmol in those>7 years, IH was 8.3% and 6.7% from 24h- urine and spot urine, respectively. Conclusion: Children and adolescents with PMNE are in risk of hypercalciuria. Therefore, it is useful to examine 24 hours of urine calcium excretion in these patients

Hypertension in obese children and adolescents

Obesity, especially upper body fat distribution, has become an increasingly important medical problem in children and adolescents. Outcomes related to childhood obesity include, as in adult population, hypertension, type 2 diabetes mellitus, dyslipidemia, left ventricular hypertrophy, obstructive sleep apnea, orthopedic and socio-psychological problems. Obese children are at approximately 3-fold higher risk for hypertension from non-obese ones. Obesity-hypertension appears to be characterized by a preponderance of isolated systolic hypertension, increased heart rate and blood pressure variability, increased levels of plasma catecholamine and aldosterone, and salt-sensitivity. Lifestyle changes of weight loss, healthier diet and regular physical exercise are effective in obesity-hypertension control, though pharmacological treatment is frequently necessary. Screening for dyslipidemia and impaired glucose tolerance should be performed in paediatric patients with obese hypertension on regular basis, at least once annually or semiannually to discover metabolic syndrome and to prevent its increased cardiovascular risk. Of course, prevention of obesity is the primary goal.

Proteinuria in frasier syndrome

Introduction Frasier syndrome (FS) is a genetic form of glomerulopathy, which results from mutations in the Wilms' tumour suppressor gene (WT1). Proteinuria in FS has been traditionally considered unresponsive to any medication and FS inevitably progresses to end stage renal failure. Case Outline We present a patient with FS who had atypical clinical manifestation and unusual beneficial antiproteinuric response to renin-angiotensin system (RAS) inhibitors given in combination with indomethacin. After 13 years of follow-up, the patient is now 17-year old with normal renal functions and no proteinuria. Conclusion RAS inhibitors combined with indomethacin showed beneficial effect in our patient. Thus, this combination might be the initial treatment of patients with FS. If this treatment strategy was not satisfied for at least 3 months, then CsA would be considered to be administered taking account of the nephrotoxicity and the increased risk of malignancy. Further prospective study is required to clarify this issue.WoSScopu
