Intractable and dramatic diarrhea in liver transplantation recipient with vasoactive intestinal peptide-producing tumor after split liver transplantation: a case report.

Numai utilizatorii înregistrați pot traduce articole

Diarrhea after liver transplantation is a common complication. Vasoactive intestinal peptide-producing tumor (VIPoma) is a rare cause of watery diarrhea; 80% of such tumors occur in the pancreas, but it is rare in liver. Hypersecretion of vasoactive intestinal polypeptide can stimulate intestinal

Watery diarrhea syndrome caused by multihormonal malignant pancreatic islet cell tumor secreting somatostatin, vasoactive intestinal peptide, serotonin, and prostaglandin E--a clinicopathological, biochemical, immunohistochemical, and ultrastructural study.

The pathophysiological, biochemical, histological, ultrastructural, and immunohistochemical characters of a case of malignant pancreatic islet cell tumor with watery diarrhea syndrome were carefully investigated. Four hormones or mediators--somatostatin (SST), vasoactive intestinal peptide (VIP),

Watery diarrhea, hypokalemia and achlorhydria syndrome is a rare cause of chronic secretory diarrhea arising from a vasoactive intestinal peptide releasing tumor. In this article, a 15-month old female patient with watery diarrhea and abdominal distension which lasting four months is presented. In

Intractable diarrhea in a boy with vasoactive intestinal peptide-producing ganglioneuroblastoma.

A 1-year-old boy had intractable diarrhea and symptoms of the watery-diarrhea-hypokalemia-achlorhydria (WDHA) syndrome, a well-known entity in adults. Resection of a ganglioneuroblastoma situated in the neck caused prompt relief of symptoms. The ganglioneuroblastoma in this instance contained the

Watery diarrhea syndrome in an adult with ganglioneuroma-pheochromocytoma: identification of vasoactive intestinal peptide, calcitonin, and catecholamines and assessment of their biologic activity.

A case of adult ganglioneuroma-pheochromocytoma with an associated watery diarrhea syndrome is reported. High levels of vasoactive intestinal peptide (VIP) were found in preoperative serum and in tumor tissue. The serum VIP levels fell to normal, and the watery diarrhae syndrome completely ceased

Peptide histidine-methionine immunoreactivity in plasma and tissue from patients with vasoactive intestinal peptide-secreting tumors and watery diarrhea syndrome.

Numai utilizatorii înregistrați pot traduce articole

The presence of peptide histidine-methionine (PHM)-like peptides has been determined in plasma and tumor specimens from patients with vasoactive intestinal peptide (VIP)-secreting tumors and the watery diarrhea syndrome. All patients had strikingly elevated plasma concentrations of PHM

Experimental evidence for vasoactive intestinal peptide as the cause of the watery diarrhea syndrome.

Numai utilizatorii înregistrați pot traduce articole

We have infused pure porcine vasoactive intestinal peptide (VIP) into 8 healthy ambulant unsedated pigs. At plasma VIP levels closely comparable to those found in the human Verner-Morrison syndrome, gross watery diarrhea and hypokalemia were produced. When the VIP infusion was discontinued the water

Rapid changes of serum vasoactive intestinal peptide after removal of ganglioneuroblastoma with watery-diarrhea-hypokalemia-achlorhydria syndrome in a child.

A 23-month-old girl with intractable diarrhea that had persisted for the past 6 months showed typical evidence of water-diarrhea-hypokalemia-achlorhydria (WDHA) syndrome. Serum vasoactive intestinal peptide (VIP)-like immunoactivity was very high, and urine homovanillic acid and noradrenaline were

Rare Cases of Pediatric Vasoactive Intestinal Peptide Secreting Tumor With Literature Review: A Challenging Etiology of Chronic Diarrhea

Numai utilizatorii înregistrați pot traduce articole

Vasoactive intestinal peptide (VIP) secreting tumor (VIPoma) is a rare disease, presenting with profuse diarrhea, electrolyte imbalance, and possibly fatal outcome. The diagnosis and treatment are challenging, and no consensus guideline of management is available. The pediatric incidence remains

Mast cell number, substance P and vasoactive intestinal peptide in irritable bowel syndrome with diarrhea.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Recent studies have shown that mast cells play an important role in irritable bowel syndrome (IBS). We investigated the relationship between mast cells and the gut hormones substance P and vasoactive intestinal peptide (VIP) in irritable bowel syndrome with diarrhea

The case of a 6-month old infant presenting with profuse diarrhea associated with increased plasma V.I.P. (600 pg/ml) is reported. The increased excretion of V.I.P., most probably of tumoral origin may be considered as responsible for the diarrhea. The discovery of an increased plasma level of
