The effect of 4 mg Molsidomine iv. followed by a continuous infusion of 3 mg per hour for 3 hours on arterial blood pressure, pulmonary artery pressure, cardiac index, peripheral and pulmonary vascular resistance and heart rate was evaluated in eleven patients suffering from chronic heart failure caused by non-ischaemic dilatative cardiomyopathy (NYHA II-III). A significant decrease in systemic blood pressure, systolic and mean pulmonary artery pressure and pulmonary wedge pressure was observed and also a marked decrease in total peripheral and pulmonary vascular resistance. There was a slight, but not significant increase in cardiac index. The heart rate did not change significantly. Treatment had to be stopped in one patient because of side effects (hypotension, nausea).

Tiazofurin is a novel C-nucleoside with significant antitumor activity in murine tumor models. In a phase I clinical trial, patients received tiazofurin by bolus iv infusion daily for 5 days. Six doses ranging from 550 to 4100 mg/m2/day were evaluated. Thirty-one treatment courses were initiated in 21 patients. Tiazofurin induced multiple, transient toxic effects at all but the lowest dose level, and treatment interruption was a common result. Nine of 28 treatment courses initiated at doses greater than or equal to 1100 mg/m2/day were interrupted at less than 5 days; only five of eight courses initiated at 1100 mg/m2/day were completed. Symptoms leading to treatment interruption included headache, nausea and emesis, and lethargy and malaise. Other significant, transient toxic effects included skeletal muscle injury manifest as pain, weakness, or serum biochemical abnormalities; mucocutaneous effects; and mental or mood changes. One case each of transient pericarditis and fatal cardiomyopathy occurred at the highest dose. Myelosuppression was observed but was transient and not dose limiting. In addition to leukopenia and thrombocytopenia, unexpected declines in serum hemoglobin were observed, although these were of uncertain significance. Tiazofurin induced significant increases in uric acid production which could be reversed with coadministration of allopurinol. Pharmacokinetic analysis revealed tiazofurin plasma elimination to be at least biphasic, with a beta-half-time of 4.2 hours; most of an injected dose could be recovered from the urine as unaltered compound within 24 hours. From this study we conclude that an appropriate dose for phase II trials with this schedule is less than or equal to 1000 mg/m2/day. The schedule may be a difficult one for clinical evaluation of antitumor activity, however, because of the possibility of frequent treatment interruption due to multiple systemic toxic effects.

Five cardiology centers conducted open-label prospective trials of meobentine sulfate, an intravenously and orally available analog of bethanidine, to assess its potential for treatment of recurrent, drug refractory ventricular tachycardia (VT) or fibrillation (VF), and complex ventricular arrhythmias. The study population comprised 26 patients (mean age, 61 years); 18 were men. Coronary artery disease was present in 15, cardiomyopathy in six, and valvular heart disease in three. Patients presented with both VT and VF (seven), sustained VT alone (12), or frequent ventricular ectopy (PVCs) and nonsustained VT (seven). Of the 26 patients, 5 were enrolled in antiarrhythmic studies (chronic PVC suppression) and 21 were enrolled in programmed electrical stimulation (PES) studies. Two of five in the chronic PVC study showed greater than 75% arrhythmia suppression. Among 21 patients in PES studies, there were eight intravenous (16 mg/kg) and 19 oral trials (400 to 1000 mg every 6 hours, 3 days/dose interval). Five of 22 patients showed efficacy at repeat PES study (neither VT nor VF), one showed partial efficacy, and four were not restudied because of clinical arrhythmia (three) and/or adverse effects (two). Overall, three patients (12%) were continued on the drug for an extended period of time. Adverse experience included hypotension in 50% and gastrointestinal effects (nausea, vomiting, or diarrhea) in 56% (oral trials only). Adverse reactions led to drug discontinuation in six and dosage reduction in eight patients. Thus, meobentine may prevent induction of VT or VF or reduce frequency of complex PVCs in selected patients refractory to other antiarrhythmic agents, but the response rate is relatively low. Symptomatic hypotension or gastrointestinal adverse effects are common and may limit utility of meobentine as a chronic oral antiarrhythmic agent.

The purpose of this study was to evaluate acute and chronic therapeutic effects of the positive inotropic vasodilating agent amrinone. 50 patients with cardiomyopathy or coronary artery disease and left heart failure participated in the study. Swan-Ganz catheterisation was used in 15 patients; following injection of 1.5 mg/kg amrinone, the mean pulmonary pressure decreased by 26%, the wedge pressure by 27%. Cardiac index rose by 18% (p less than 0.01). 35 patients were examined in the oral study, the avg. dose being 300 mg/day. After 2 and 12 weeks of therapy, exercise tolerance increased by 22% and 13% respectively (p less than 0.05). Cardiac output after maximal workload as determined by equilibrium radionuclide ventriculography increased by 27% and 30% respectively (p less than 0.05). 34 side effects occurred in 23 of 35 patients: nausea, orthostasis, angina pectoris, tachyarrhythmia, hepatotoxicity, thrombocytopenia, hyperuricemia and brown coloring of finger-nails. From the hemodynamic point of view amrinone is intravenously and orally effective. Careful selection of patients and frequent examinations are however necessary.

Eighty-three patients with advanced soft tissue sarcoma who had received no prior chemotherapy entered a randomised phase II study comparing carminomycin (CMM) 20 mg/m2 with adriamycin (ADM) 75 mg/m2, both administered i.v. bolus every 3 weeks. Six patients were ineligible and response could not be evaluated in 6 additional patients. Thirty-eight evaluable patients received ADM and 33 received CMM. There was one complete response to ADM and 10 partial responses, an overall response rate of 29%. CMM showed significantly (P = 0.01) lower antitumour activity--one partial response (3%). Stabilisation of disease was similar in both arms (47 and 45%), but fewer patients progressed on ADM (24 compared to 52%). Durations of response dating from the start of chemotherapy were 5 months for complete remission on ADM, a median of 7 months (range 4-17) for partial response on ADM and 14 months for the one partial remission on CMM. Although the median time to progression for all patients receiving CMM (2 months) was significantly (P = 0.001) shorter than for those receiving ADM (5 months), patients on ADM had only a marginally significant longer duration of survival (P = 0.06) than the patients receiving CMM. A leucocyte nadir less than 2.0 X 10(9)/l occurred in 38% of patients receiving ADM and 43% receiving CMM. Anaemia and thrombocytopoenia were uncommon. Other toxicities such as nausea, vomiting, anorexia and alopecia were more severe in the ADM group. There was one infective death secondary to leucopoenia in the ADM arm, and one patient who had received 109 mg/m2 CMM + 255 mg/m2 ADM developed progressively fatal cardiomyopathy.

Twenty-two patients who had metastatic breast cancer previously treated with combination chemotherapy, cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) or CMF with vincristine and prednisone, were treated with Carminomycin (carubicin) 20 mg/m2 body surface area by intravenous bolus injection once every 3 weeks. Of 21 evaluable patients, 1 patient achieved complete remission, 5 patients achieved partial responses, and 11 remained stable. Cases of acute drug toxicity included myelosuppression, phlebitis, and gastrointestinal symptoms; there were four cases of mild alopecia, which consisted of thinning of the scalp hair. There were three cases of biopsy-proven cardiomyopathy, contrary to previous reports from the United Soviet Socialist Republic, which indicated that this drug was relatively free of cardiotoxicity. The median duration of remission for responders was 23 weeks. It is believed that Carminomycin has significant activity against metastatic breast cancer and, because its side effects, especially nausea, vomiting, and alopecia, were considerably milder than those experienced with Adriamycin, further investigation of this drug is warranted.

Sixty-four adult patients with soft-tissue sarcomas received adjuvant chemotherapy with a six-drug combination regimen after surgery. Seventy percent remain free of disease with a median follow-up of 50 months. Only seven patients have died of their disease, all within the first 24 months after surgery. Most patients experienced severe nausea and vomiting secondary to the actinomycin D and dacarbazine parts of the protocol, and three patients experienced frank Adriamycin cardiomyopathy. Toxicity from this combination was otherwise mild. The 58% recurrence rate of 12 patients who discontinued therapy early because of nausea was significantly greater than the 23% rate for those who completed or relapsed on therapy (P = 0.01). Adjuvant chemotherapy should be considered after surgery for patients with soft-part sarcomas, especially those with high-grade tumors that have a considerable risk of recurrence.

We report the case of a 42-year-old female, affected by mitral valve prolapse and ventricular arrhythmias, who died suddenly from ventricular fibrillation recorded during Holter monitoring. The lethal arrhythmia initiated with late diastolic couplets followed by a ventricular tachycardia that eventually degenerated into ventricular fibrillation. The patient had experienced four orthostatic and stress-related syncopal episodes, associated with nausea and diaphoresis, and a positive tilt test. Holter monitoring documented ventricular arrhythmias, consisting of both isolated monomorphic and sporadic repetitive beats. Her standard ECG and exercise test were normal, but signal-averaged study findings were significantly positive. QT prolongation in the absence of arrhythmias was observed during the Valsalva manoeuvre and isoproterenol infusion. 2D echo showed a remarkable mitral valve prolapse without regurgitation and localized structural abnormalities of the right ventricle. Postmortem study confirmed mitral valve prolapse, and also disclosed pulmonary infundibulum dilatation, massive adipose infiltration of the right ventricular free wall, patchy fibrosis and scattered myocardial inflammatory infiltrates in the left ventricle; these features are all consistent with arrhythmogenic right ventricular cardiomyopathy.

Interferon alpha is a biologic agent with demonstrated anti-tumor activity in a variety of hematologic and solid malignancies. Many patients treated with interferon experience acute toxicity manifested as a flu-like syndrome of fever, chills, myalgias, and malaise. However, fatigue, anorexia, bone marrow suppression, nausea, vomiting, dizziness, and confusion may also occur. Cardiotoxicity is a rare complication of interferon therapy that most frequently presents as transient episodes of hypotension and tachycardia, with few significant life-threatening cardiovascular effects reported. A small number of cases of suspected interferon-induced cardiomyopathy, all of which improved after discontinuing interferon, have recently been documented. We report a patient with multiple myeloma who developed severe congestive cardiomyopathy while receiving interferon alpha that did not reverse subsequent to discontinuation of interferon therapy. Although the patient had previously received doxorubicin, the presence on endomyocardial biopsy of a prominent intracellular lipid accumulation within myocytes and only grade 2 anthracycline cardiotoxicity suggested that other or additional factor(s) contributed to the severity of this patient's cardiomyopathy. Etiologies of cardiac dysfunction other than interferon and doxorubicin were excluded. While a direct cause-effect relationship between interferon alpha and irreversible congestive cardiomyopathy cannot be firmly established in this case report, patients who either concurrently or sequentially receive interferon and anthracyclines should be carefully monitored for evidence of cardiac toxicity.

Forty chemotherapy naive patients with metastatic or locally advanced breast cancer were treated in a randomized trial comparing mitozantrone 14 mg/m2 with epirubicin 75 mg/m2 given intravenously at 3-weekly intervals. There was a 40% (95% confidence interval (CI) 8-72; P = 0.013) higher partial response rate with epirubicin (11/18) than with mitozantrone (4/19). Epirubicin caused significantly more alopecia (difference 76%; 95% CI 57-96; P < 0.0001) and nausea/vomiting (difference = 38%; 95% CI 10-67; P = 0.01). Three patients who received long courses of epirubicin experienced cardiac failure; two were proved to have cardiomyopathy. The median survival for the epirubicin and mitozantrone groups were 9.5 and 8 months respectively. Thus, although epirubicin gave a higher response rate it also caused more toxicity.
