BACKGROUND Although inhibition of the renin-angiotensin system delays the progression of renal failure in adults with chronic kidney disease, the blood-pressure target for optimal renal protection is controversial. We assessed the long-term renoprotective effect of intensified blood-pressure control among children who were receiving a fixed high dose of an(More)
Coronary artery calcification (CAC) is common in adults with end-stage renal disease (ESRD), but little is known about the prevalence and the extent of it in children. We used multidetector spiral computed tomography (MDCT), echocardiography, and carotid and brachial high-resolution ultrasonography to screen for the presence and predisposing factors of CAC(More)
OBJECTIVE To evaluate the frequency of vasculitis, mainly in the forms of Henoch-Schönlein purpura and polyarteritis nodosa (PAN), and to investigate the presence of occult blood in the first stool specimens after an abdominal attack in Turkish patients with familial Mediterranean fever (FMF). METHODS Review of the charts of 207 patients with FMF seen(More)
Cardiovascular disease (CVD) is the principal cause of mortality in patients with end-stage renal disease (ESRD). The aim of this study was to analyze carotid intima-media thickness (cIMT), endothelium-dependent dilatation (EDD), and left ventricular mass index (LVMI) as the cardiovascular risk markers and to investigate the independent risk factors of(More)
OBJECTIVE To retrospectively evaluate the clinical features, angiographic findings, and outcomes of children with Takayasu arteritis (TA) in Turkey. METHODS Clinical, laboratory, and angiographic findings and outcomes of 19 children with TA were evaluated with a retrospective chart review. The criteria for inclusion were those proposed by the American(More)
BACKGROUND AND OBJECTIVES Steroid-resistant nephrotic syndrome is a rare kidney disease involving either immune-mediated or genetic alterations of podocyte structure and function. The rare nature, heterogeneity, and slow evolution of the disorder are major obstacles to systematic genotype-phenotype, intervention, and outcome studies, hampering the(More)
Increased left ventricular (LV) mass in children with chronic renal insufficiency (CRI) might be adaptive to sustain myocardial performance in the presence of increased loading conditions. It was hypothesized that in children with CRI, LV systolic function is impaired despite increased LV mass (LVM). Standard echocardiograms were obtained in 130 predialysis(More)
Coronary artery calcification (CAC) is common in adults with chronic kidney disease (CKD) and progresses with time. However, data are limited for younger patients. We have previously reported CAC in eight of 53 children with CKD. After 2 years, CAC evaluation was repeated in 48 patients. The median CAC score (CACS) increased from 101.3 (1473.6 ± 1978.6,(More)
Genetic screening paradigms for congenital and infantile nephrotic syndrome are well established; however, screening in adolescents has received only minor attention. To help rectify this, we analyzed an unselected adolescent cohort of the international PodoNet registry to develop a rational screening approach based on 227 patients with nonsyndromic(More)
A total of 66 children and adolescents with chronic kidney disease (CKD) (20 pre-dialysis patients and 46 chronic dialysis patients) were evaluated to address the prevalence of abnormalities in glucose and insulin metabolism and their association with cardiovascular disease. Glucose intolerance was assessed using an oral glucose tolerance test; insulin(More)
