Abstract: | Leptin is an adipocyte-secreted hormone which plays a key role in energy homeostasis.
Recent “proof of concept” studies involving leptin administration to humans support its
critical role in regulating energy homeostasis, neuroendocrine and immune function as well
as insulin resistance in states of energy/ caloric deprivation. Moreover, interventional
studies in leptin deficient children and observational studies in normal girls and boys
support a role for leptin as a permissive factor for the initiation of puberty in
children. The potential clinical usefulness of leptin in several disease states in
children and adolescents, including hypothalamic amenorrhea, eating disorders and
syndromes of insulin resistance is still under investigation. |
