Hypopituitarism due to sports related head trauma and the effects of growth hormone replacement in retired amateur boxers

Abstract

Traumatic brain injury (TBI) has been recently recognized as a leading cause of pituitary dysfunction. Current data clearly demonstrated that sports related head trauma due to boxing, kickboxing, and soccer might results in pituitary hormone deficiencies, isolated growth hormone (GH) deficiency in particular. In the present report physiologic dose GH replacement therapy (GHRT) was performed in two GH deficient retired amateur boxers for the first time. The boxers received recombinant GH for 6 months. After 6 months of GHRT there were substantial improvements, but not complete normalization, in the body composition parameters, lipid profiles and quality of life scores in both boxers. These preliminary results suggest that GHRT may have beneficial effects in retired boxers with severe isolated GH deficiency due to sports related head trauma. But more data with higher number of boxers and longer GHRT duration are warranted.
