What does the vasoactive intestinal peptide do?
A hormone found in the pancreas, intestine, and central nervous system. It has many actions in the body, such as helping to control the secretion of water, salts, enzymes, and gastric acid during digestion.
What does high vasoactive intestinal peptide mean?
A very high level is usually caused by a VIPoma. This is an extremely rare tumor that releases VIP. VIP is a substance found in cells throughout the body. The highest levels are normally found in cells in the nervous system and gut.
What stimulates vasoactive intestinal peptide?
VIP stimulates contractility in the heart, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea, stomach and gallbladder. In humans, the vasoactive intestinal peptide is encoded by the VIP gene….Vasoactive intestinal peptide.

What causes high VIP plasma?
Other known causes of elevated levels of VIP, ranging from 80 to 340 pg/mL, included other neurogenic tumors (n = 3), small- bowel resection (n = 2), inflammatory bowel disease (n = 2), chronic renal failure (n = l), and prolonged fasting (n = 1).
What vasoactive means?
Listen to pronunciation. (VAY-zoh-AK-tiv) Describes something that causes the blood vessels to constrict (get narrower) or dilate (get wider).
Which disease is known as VIP disease?
(Werner-Morrison Syndrome) A vipoma is a non-beta pancreatic islet cell tumor secreting vasoactive intestinal peptide (VIP), resulting in a syndrome of watery diarrhea, hypokalemia, and achlorhydria (WDHA syndrome). Diagnosis is by serum VIP levels.
What is VIP tumor?
A very rare tumor that usually forms in the islet cells of the pancreas and makes the hormone vasoactive intestinal peptide (VIP). VIP helps control the secretion of water, salts, enzymes, and gastric acid during digestion and relaxes certain muscles in the digestive tract.
What is VIP in pancreas?
Vasoactive Intestinal Peptide–Secreting Pancreatic Neuroendocrine Tumor. VIP is a small peptide normally found in the brain, G cells of the antrum, adrenal medulla, gut mucosa, pancreatic neurons, and D2 cells of the pancreas.
What causes VIP secretion?
Vasoactive intestinal peptide (VIP) is a neuropeptide synthesized and released by immune cells, as well as by nerve endings that synapse on central and peripheral lymphoid organs.
Is VIPoma benign or malignant?
Vipomas are a type of pancreatic endocrine tumor that arises from islet cells. Of these tumors, 50 to 75% are malignant, and some may be quite large (7 cm) at diagnosis. In about 6%, vipoma occurs as part of multiple endocrine neoplasia.
What is a VIP test?
Test Code: VIP. VIP (Vasoactive Intestinal Polypeptide) Detection of vasoactive intestinal polypeptide producing tumors in patients with chronic diarrheal diseases. Fasting Required. Specimen Type.
