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 ob...

Hypothalamic amenorrhea (HA) is associated with dysfunction of the hypothalamic-pituitary-peripheral endocrine axes, leading to infertility and bone loss, and usually is caused by chronic energy deficiency secondary to strenuous exercise and/or decreased food intake. Energy deficiency also leads to hypoleptinemia, which has been proposed, on the basis of observational studies as well as an open...

Neuromyelitis optica (NMO) has been reported to be associated with endocrinopathies, such as amenorrhea, galactorrhea, and diabetes mellitus. However, its association with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) is extremely rare. We herein report an adult case of NMO with SIADH in a female Chinese patient. The patient was aquaporin-4 antibody positive, and her hypo...
