Seventeen patients with malignant carcinoid tumour, ten of whom had the malignant carcinoid syndrome, were treated with recombinant alpha-2b interferon by subcutaneous injection (3 MU per dose) three times per week for a median of 12 weeks (range 4-48). No objective tumour responses were observed; however, there was a greater than 50% reduction in 24-hour urinary 5-hydroxyindolacetic acid (5-HIAA) excretion in four of ten patients (40%) with elevated pretreatment levels. Five of ten patients (50%) with flushing, five of seven patients (71%) with diarrhoea and both patients with wheezing experienced relief of symptoms. Three of four patients (75%) with weight loss as their only problem experienced weight gain. Responses occurred within the first eight weeks of treatment, but were generally of short duration. Toxicity occurred in all patients, and consisted mainly of fever, chills, anorexia, fatigue and weight loss. Four patients ceased therapy due to toxic reactions. Although interferon has activity against carcinoid tumours, its benefits are short-lived and toxicity limits its use with increasing dose. Patients with carcinoid syndrome appear to achieve the best therapeutic response, and it is likely that low doses (9-20 million IU weekly) are as effective as higher doses (36-72 million IU weekly).

Twenty-seven patients with metastatic carcinoid tumor, 24 of whom had the malignant carcinoid syndrome, were treated with recombinant leukocyte A interferon at a planned dose of 24 x 10(6) U/m2. Twenty percent of patients with measurable tumor experienced an objective regression and 39% of those with the carcinoid syndrome experienced a reduction of more than 50% in urine 5-hydroxyindoleacetic acid (5HIAA) excretion. Flushing was partially or completely relieved in 65% of patients and diarrhea was relieved in 33%. Regrettably, these favorable treatment effects were transient in nature, with objective regressions persisting for a median of only 7 weeks and hormonal responses for a median of only 4 weeks. Any therapeutic gain experienced by these patients seemed to be outweighed by the frequency and severity of toxic reactions, which consisted primarily of chills and fever, fatigue, anorexia, weight loss, leukopenia, and abnormalities of liver function. Whereas other interferons, administration by alternative dosages and regimens, or incorporation of interferons into drug combinations may merit future study, we cannot recommend recombinant leukocyte A interferon, administered by the methods we employed, for routine therapy of the carcinoid tumor or syndrome.

Serotonin syndrome, a condition with numerous clinical neurological manifestations, is the result of central serotonergic hyperstimulation. Features of the syndrome include mental status and behavioral changes (agitation, excitement, hypomania, obtundation), motor system involvement (myoclonus, hemiballismus, tremor, hyperreflexia, motor weakness, dysarthria, ataxia) and autonomic symptoms (fever, chills, diarrhea). Serotonin syndrome has been reported exclusively in patients on medications for psychiatric illness and Parkinsonism, despite the fact that the putative action of many antimigraine agents also involves the serotonin system. We herein report six patients with migraine who developed symptoms suggestive of the serotonin syndrome. Five were taking one or more serotomimetic agents for migraine prophylaxis (sertraline, paroxetine, lithium, imipramine, amitriptyline). In each case the symptoms and signs developed in close temporal proximity with use of a migraine abortive agent known to interact with serotonin receptors. In three instances the agent was subcutaneous sumatriptan and, in three, intravenous dihydroergotamine. In each instance the symptoms were transient and there was full recovery. With the ever increasing use of migraine medications active at serotonin receptor sites, cases of serotonin syndrome will likely occur more frequently. It is important that physicians treating migraine are aware of the serotonin syndrome and are able to recognize its varying presentations.
