Growth failure is often seen in nephrotic children who fail to respond to glucocorticoid therapy or are glucocorticoid dependent. The underlying mechanism responsible for such growth defect remains poorly understood although long-term glucocorticoid use or nephrotic syndrome (NS) has been indicated to independently affect growth. Recent clinical evidence has suggested that changes in the serum levels of insulin-like growth factors (IGFs) and IGF-binding proteins (IGFBPs) among these children. The loss of insulin-like growth factor-I (IGF-1) and IGFBP-3 found in nephrotic children may directly prompt growth defect and retardation. In addition, glucocorticoid is believed to be associated with overt elevation of serum IGF-I levels suggesting potential development of IGF resistance, one of the main factors responsible for persistent growth retardation. Growth hormone therapy has been shown to effectively reconcile this IGF resistance. The present review will discuss the complex relationship among IGF, IGFBPs, and glucocorticoid in children with NS.

UI	MeSH Term	Description	Entries
D009404	Nephrotic Syndrome	A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D005938	Glucocorticoids	A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.

D013002	Somatomedins	Insulin-like polypeptides made by the liver and some fibroblasts and released into the blood when stimulated by SOMATOTROPIN. They cause sulfate incorporation into collagen, RNA, and DNA synthesis, which are prerequisites to cell division and growth of the organism.	Sulfation Factor,Somatomedin,Factor, Sulfation
