Metabolic co-morbidities revealed in patients with childhood-onset adult GH deficiency after cessation of GH replacement therapy for short stature.

GH therapy was approved in 2006 for treatment of adult growth hormone deficiency (GHD) in Japan. Until then, GH was used only to treat short stature in children with GHD and the treatment was stopped when the final height was reached. In the present study, we investigated metabolic co-morbidities experienced by adults with childhood-onset (CO) GHD after the cessation of GH.

Clinical features of insulin-like growth factor-II producing non-islet-cell tumor hypoglycemia.

In some patients with non-islet-cell tumor hypoglycemia (NICTH), a high molecular weight form of IGF-II (big IGF-II) derived from tumors is present in the circulation and might be associated with recurrent hypoglycemia. In this study, in order to survey the clinical characteristics of patients with IGF-II producing NICTH, we analyzed the medical records of 78 patients with NICTH (M/F 44/34, age 62+/-1.8, range; 9-86 years.

Serum adiponectin levels in adult growth hormone deficiency and acromegaly.

Atherosclerosis and insulin resistance are common complications of adult growth hormone deficiency (GHD) and acromegaly. Circulating adiponectin, an adipocyte-derived protein, has both anti-atherogenic and insulin-sensitising effects. In this study, we measured serum adiponectin levels in patients with either adult GHD or acromegaly to clarify the impact of GH secretory states on the regulation of serum adiponectin levels.

Acid-labile subunit in growth hormone excess and deficiency in adults: evaluation of its diagnostic value in comparison with insulin-like growth factor (IGF)-I and IGF-binding protein-3.

In serum, insulin-like growth factors (IGFs) are primarily present as a approximately 150 kDa ternary protein complex, which consists of IGFs, IGF binding protein-3 (IGFBP-3), and acid-labile subunit (ALS). Like IGF-I and IGFBP-3, serum levels of ALS depend on growth hormone (GH). To date, the diagnostic relevance of ALS in adult GH deficiency (GHD) has remained uncertain.
