A Phase I trial of acivicin [L-(alpha S,5S)-alpha-amino-3-chloro-4,5-dihydro-5-isoxazoleacetic acid] has been performed on an escalating-dosage 24-hr continuous i.v. infusion schedule. Thirty-one patients received 77 courses of treatment, and all but one were evaluable for toxicity. Pharmacological monitoring in selected patients demonstrated that peak plasma levels correlated with dose. Postinfusion t1/2 beta was 6 to 9 hr, and urinary recovery of the administered dose was 14 to 19% as unchanged drug during the 24-hr infusion. Hematological and gastrointestinal toxicities were variable and not dose related. In contrast, neurotoxicity characterized by lethargy, fatigue, confusion, disorientation, hallucinations, nightmares, and truncal ataxia was dose limiting and related to plasma drug levels. A minimal antitumor response was observed in a patient with colorectal carcinoma, and a partial response occurred in a patient with liver metastases from gastric carcinoma. The recommended dose for Phase II trial by 24-hr infusion is 160 mg/sq m.

Obstructive sleep apnoea syndrome (OSAS) appears to be an extremely rare complication of carcinoid syndrome and has not yet been reported in the literature. We describe a 75-year-old patient with a history of bronchial carcinoid who besides typical carcinoid syndrome symptoms developed sleep disturbance and day lethargy caused by massive facial and nasal tissue oedema. Sleep apnoea was confirmed by sleep study. Abdominal ultrasound and computed tomography (CT) scan showed the presence of multiple liver metastases. Because the patient did not respond to octreotide therapy, embolization of the hepatic artery was performed. After this procedure we observed dramatic improvement of the patient's life quality, and rapid disappearance of facial swelling and sleep apnoea symptoms. We conclude that hepatic artery embolization appeared to be an effective method of abolishing obstructive sleep apnoea associated with carcinoid syndrome.

A 64-year-old nondiabetic woman presented with spells of lightheadedness and diaphoresis associated with lethargy and hunger of 2 weeks' duration. Physical examination was unremarkable; however, her fasting plasma glucose was 66 mg/dl, with concurrent plasma insulin of 171 microIU/ml (normal, 5-27 microIU/ml). Her C-peptide and pro-insulin levels were elevated, with negative insulin antibody and negative urinary sulfonylurea levels. Abdominal computed tomographic scan demonstrated a 5 x 4-cm mass in the tail of the pancreas and many liver metastases. She underwent resection of the pancreatic mass, radiofrequency ablation, and cauterization of hepatic lesions. Histology confirmed pancreatic insulinoma. Ten months later, she was free of hypoglycemic symptoms, with normal plasma insulin C-peptide and significantly decreased proinsulin levels. Insulinomas are rare, predominantly benign tumors. Surgery is the only curative treatment. Octreotide can be used to control hormone secretion and tumor growth. Other treatments include hepatic embolization, radiotherapy, chemotherapy, and liver transplantation.
