[Diagnosis of Verner-Morrison syndrome (VDHA) and its treatment with sandostatin an streptozocitin].
A case report is presented of a man with Verner-Morrison syndrome of extreme severity, caused by an unresectable pancreatic VIPoma. The pathological role of vasoactive intestinal polypeptide (VIP) is discussed in the pathogenesis of Watery Diarrhoea, Hypokalaemia, Achlorhydria (WDHA) syndrome. The authors describe the typical symptoms of the syndrome and provide a diagnostic and therapeutic strategy. Plasma level of VIP was determined by the authors' own VIP RIA method. Administration of a long acting somatostatin analogue, octreotide (Sandostatin, Sandoz) at a dose of 100 micrograms daily, decreased the plasma level of VIP from about 55 to 38 fmol/ml, which was associated with complete regression of the diarrhoea. Due to the 'escape phenomenon' the dose of Sandostatin was gradually increased and finally completed with streptozotocin (Zanosar, Upjohn) administration, which was repeated every 8 weeks. The combination of Sandostatin and streptozotocin resulted in complete regression of diarrhoea and substantial diminution of the tumour mass. The patient displayed a weight gain and returned to normal life.
