xanthogranulomaSellar xanthogranuloma is a rare cause of idiopathic arginine vasopressin deficiency (AVP-D). We are reporting a case of AVP-D and cutaneous and sellar xanthogranuloma. The patient was diagnosed with AVP-D 11 years ago, but sellar magnetic resonance imaging was not done at ...
Severe hemorrhagic shock, however, is associated with a state of arginine vasopressin (AVP) deficiency, and supplementation of this hormone may decrease the need for blood products in resuscitation. Objective To determine whether low-dose supplementation of AVP in patients with trauma (hereinafter ...
A clinical test that measures hGH secreted by the pituitary gland in response to arginine, which is used to evaluate infants with growth retardation and adults with pituitary tumours. Ref range ▪ Children—48 ng/ml; ▪ Males—10 ng/m; ...
Stimate®鼻喷雾剂含有作为活性物质的醋酸去氨加压素(desmopressin acetate),它是天然激素精氨酸加压素 (Arginine vasopressin) 的合成类似物。一喷( 0.1 mL, 150 μg)Stimate®鼻腔喷雾溶液具有约600国际单位的抗利尿活性。Stimate®Nasal Spray的半衰期在3.3到3.5小时之间,鼻内剂量范围为150到450 μg 。Stimate...
Solid organ donors often develop hypotension due to vasodilation, and recently we observed that a variety of vasodilatory states are characterized by vasopressin deficiency and hypersensitivity. Thus, we investigated the prevalence of vasopressin deficiency in hypotensive solid organ donors without clinical ...
The blood-brain barrier (BBB) plays a significant pathophysiological role in multiple sclerosis (MS). Vasopressin (AVP) is released after brain injury and contributes to the inflammatory response. We propose that AVP may be modulating BBB permeability an
Six novel mutations in the arginine vasopressin gene in 15 kindreds with autosomal dominant familial neurohypophyseal diabetes insipidus give further insig... Autosomal dominant familial neurohypophyseal diabetes insipidus (adFNDI) is caused by postnatal arginine vasopressin (AVP) deficiency resulting from ...

Twenty-nine patients had vasopressin deficiency, 10 had TSH deficiency, 8 had gonadotropin deficiency, and 4 had ACTH deficiency. The median peak GH response to insulin test was 2.1 μg/liter (range, 1.1-2.9), whereas it was 1.5 μg/liter (range, 1.3-2.4) after ARG. The median peak ...
