Effect of Growth Hormone on Leptin, Cytokines and Body Composition of Children With Growth Failure Due to Chronic Kidney Disease
Circulating concentrations of cytokines, such as leptin, tumor necrosis factor-alpha and interleukins 1 and 6 are increased in patients with chronic kidney disease (CKD). In light of the increasing recognition that growth hormone receptor signaling involves cytokine pathway activation, the investigators hypothesize that maladaptation of cytokine regulation in chronic kidney disease may underlie growth failure. Secondly, they hypothesize that administration of recombinant human growth hormone (rhGH) will result in growth rate stimulation in pre-pubertal children with growth impairment due to chronic kidney disease by down regulation of the cytokine pathways.
This is a non-randomized open-label study to evaluate the effect of recombinant human growth hormone on biochemical/metabolic and immunologic parameters in relation to body composition pre- and post-recombinant human growth hormone therapy of pre-pubertal growth hormone naive children. The efficacy of recombinant human growth hormone to improve growth velocity in pre-pubertal children with growth failure is a secondary objective. Fifteen children are to be studied over a six month period. Each patient will serve as his/her own control. Six months of growth data prior to study is required.

|Official Title:||A Multicenter Study of the Effect of Recombinant Human Growth Hormone on Leptin and Cytokines in Relation to Body Composition in Pediatric Patients With Growth Failure Due to Chronic Kidney Disease (CKD)|
- The primary objective will be to evaluate biochemical/metabolic, and immunologic parameters in relation to body composition. [ Time Frame: pre- and post-rhGH therapy ]
- The secondary objective is to examine the efficacy of rhGH to improve growth velocity in prepubertal, rhGH naïve, children with growth failure secondary to CKD.
