Idiopathic steroid-resistant nephrotic syndrome (SRNS) has been associated with the presence of a circulating focal sclerosis permeability factor (FSPF) thought to damage the glomerular barrier and increase permeability to albumin. Galactose binds and inactivates FSPF in vitro, but its effect in vivo is uncertain. A prospective clinical trial was conducted(More)
Carnitine plays a key role in energy production in the myocardium. Carnitine deficiency commonly occurs in patients on chronic hemodialysis (HD) and may contribute to cardiomyopathy. Carnitine levels and cardiac function of nine children on HD were assessed before and after 6 months of intravenous levocarnitine supplementation. Standard echocardiographic(More)
The accrual of healthy bone during the critical period of childhood and adolescence sets the stage for lifelong skeletal health. However, in children with chronic kidney disease (CKD), disturbances in mineral metabolism and endocrine homeostasis begin early on, leading to alterations in bone turnover, mineralization, and volume, and impairing growth. Risk(More)
VitD deficiency and bone disease are common after Tx. Prevalence and risk factors for low VitD and BMD and response to VitD therapy were investigated in pediatric renal Tx recipients. 25-hydroxy VitD levels of 71 Tx were compared to 54 healthy AA children. DXA of 44 Tx were compared to 47 AA controls. Of Tx, 59% were AA. Majority (59.1%) of Tx were VitD(More)
There are little data on prevalence of dyslipidemia in pediatric kidney TX recipients in the modern IS era. LP profiles of 38 TX recipients receiving triple IS with MMF, prednisone, and tacrolimus were compared with those of 11 children on HD using mixed model multiple linear regression analysis of repeated measures after adjusting for age, sex, ethnicity,(More)
Carnitine deficiency is known to occur in chronic hemodialysis; however, the effect of continuous renal replacement therapy (CRRT) on carnitine homeostasis has not been studied. We hypothesized that children receiving CRRT are at risk for deficiency because of continuous removal, absent intake, decreased production, and comorbidities related to critical(More)
Dear Editors, We would like to thank the authors of this “letter to the editor” for their interest in our study and for sharing their perspective [1]. We are in agreement with many of the points noted in the letter and have discussed them in our manuscript. The in vitro studies of Savin et al. [1], as well as the case reports by Kopac [2] and De Smet [3],(More)
Wewant to thank the authors of this letter to the editor for their interest in our manuscript, “Effect of galactose on glomerular permeability and proteinuria in steroid-resistant nephrotic syndrome” [1].We reported that the mean preand post-treatment urine protein:creatinine (UPC) ratios of a prospective study group of 7 children remained unchanged(More)
