The hemodynamic effects of a 10 mg bolus of edrophonium chloride followed by a continuous infusion of 0.25 to 1.0 mg per minute, were determined in unanesthetized patients with significant myocardial disease. The effect on heart rate of the drug was negated by studying a group of nine patients with complete heart block and permanently implanted ventricular pacemakers. After the 10 mg bolus, two of the nine patients experienced dizziness, nausea and abdominal cramps associated with a mild decrease in peripheral vascular resistance. There was no significant change in cardiac index, mean blood pressure, brachial artery upstroke time, corrected ejection time, or left ventricular systolic ejection time. This study demonstrated that the continuous infusion of 0.25 to 1.0 mg per minute of edrophonium chloride following a 10 mg loading dose, had no significant effect on myocardial function.

A cas is reported of a 23-year-old man who voluntarily took a massive dose of arsenic (at least 8 g). In spite of the ingested amount and the acute nature of the poisoning, the patient survived 8 days. Gastrointestinal, neurologic and cardiac features were predominant including nausea, vomiting, choleroid diarrhoea, encephalopathy, peripheral neuropathy, and finally a fatal toxic cardiomyopathy. Metabolic acidosis, moderate cytolysis and an anticoagulant effect were also observed. This unique characteristic was partly due to a circulating anticoagulant with prothrombinase activity, as well as direct antivitamin K activity. Postmortem examination revealed: a congestive oesophagitis; a necrosing gastritis involving all the stomach wall; diffuse hepatic steatosis; skin lesions with vascular congestion and dermoepidermal detachment; discrete subepicardial congestive lesions. Arsenic was found in all tissues.

Multi-center clinical trial of 123I-metaiodobenzylguanidine (123I-MIBG) was carried out to assess its utility as a scintigraphic imaging agent reflecting sympathetic neuronal function in cardiovascular field. Studies were performed on patients with heart diseases of three categories, myocardial infarction, angina pectoris and cardiomyopathy. Scintigraphic images, reflecting sympathetic neuronal function were obtained with 123I-MIBG from all of those categories of patients and the efficacy of the imaging was revealed in 781 (95.0%) out of 822 patients. In some patients abnormality was suggested in sympathetic neuronal function with 123I-MIBG imaging, in spite of normal findings with myocardial perfusion scintigraphy by 201TlCl. In all 981 patients studied with 123I-MIBG, there have been no severe adverse reactions, except complaints of burning on injection site of the agent or nausea, etc. from 4 patients. We conclude that 123I-MIBG imaging is one of the effective tools for diagnostic use reflecting topical sympathetic neuronal function in the heart, judging from its safety and efficacy.

We describe a girl aged 17 y who died after a cardiac arrest secondary to septic shock. At autopsy, the enlarged, soft, and flabby heart showed microscopic evidence of acute myocardial infarction, myocardial edema, myocardiocyte loss, replacement fibrosis in the interventricular septum, and right and left ventricular hypertrophic nucleomegaly. The pathological diagnosis was that of cardiomyopathy due to prolonged selenium deficiency. The patient had been on total parenteral nutrition for 17 mo, following extensive bowel resection for intractable pain, nausea, and vomiting caused by chronic idiopathic intestinal pseudoobstruction. Seven months before death, when severe biochemical selenium deficiency was diagnosed, supplemental selenium was added to the infusion, and plasma selenium concentrations increased. In long-standing selenium deficiency, sepsis may contribute the final insult to a damaged myocardium, triggering symptomatic cardiac failure and sudden death.

Fifteen patients with Stage IV lung cancer both untreated and previously treated were enrolled into a high-dose chemotherapy program with multiple alkylating agents and autologous bone marrow reinfusion. Eight patients received cyclophosphamide at 7.5 gm/m2 over 3 days with thiotepa escalated from levels of 1.8 mg/kg to 6.0 mg/kg over 3 days. Seven patients received the above dose of cyclophosphamide plus thiotepa at 675 mg/m2 and oral melphalan escalated from levels of 0.75 mg/kg to 2.5 mg/kg over 3 days. Both regimens are part of larger Phase I-II clinical studies. The median time to recovery of more than 500 granulocytes and more than 50,000 platelets per microliter was 16 and 27 days, respectively. Two patients died as a consequence of severe, overwhelming infections during their period of aplasia. Of the 13 evaluable patients, no patients achieved a complete response and seven patients (47%) obtained a partial response. The median duration of response was 12 weeks. Other nonhematologic toxicities included nausea/vomiting, diarrhea, mucositis, skin rash, hemorrhagic cystitis, and cardiomyopathy. Since there are substantial toxicities associated with high-dose chemotherapy and responses of such brief duration, further investigation with these drug combinations is not warranted.

Interferon-alpha (IFN-a) or 2'-deoxycoformycin (pentostatin; DCF) have each been shown to be highly active in hairy-cell leukemia (HCL). In this phase II study of the Leukemia Cooperative Group of the European Organization for Research and Treatment of Cancer (EORTC), the efficacy and toxicity of DCF were investigated in patients who were resistant to IFN-a treatment. Resistance was defined as: (1) progressive disease (PD) under IFN-a therapy for more than 2 months; (2) stable disease (SD) after more than 6 months of IFN-a treatment; (3) relapse within 3 months of discontinuing IFN-a; and (4) intolerance to IFN-a because of World Health Organization (WHO) grade 3 or 4 toxicity. DCF was applied at a dosage of 4 mg/m2 weekly x 3, then 4 mg/m2 every other week x 3. Responders were given a maintenance therapy once per month for a maximum of 6 months. At the time of report, 33 patients with resistant disease were evaluable for response and toxicity. Median duration of IFN-a therapy before DCF administration was 14.7 months (range, 1 to 41 months). Complete remissions (CRs) were achieved in 11 patients and partial remissions (PRs) in 15, resulting in a total response rate of 78.8%. Median interval between beginning of DCF therapy to best response was 3.9 months with a range from 2.0 to 7.0 months. Two patients who achieved PR have relapsed 7 and 14 months after cessation of DCF therapy. The median duration of response was over 11.5 months (range, over 3.0 to over 24.0 months). Three patients died within the first 6 weeks of DCF treatment: one of drug-unrelated cardiomyopathy and two of fungal pneumonia. The patients with early death (n = 3) and nonresponsive disease (n = 4) received IFN-a treatment for a longer period (median, 18.0 months) than did the 26 responsive patients (median, 10.0 months). Major side effects included nausea, skin rash, and infections and were otherwise mild. Thus, DCF is highly active in patients with HCL resistant to IFN-a.

Twenty patients with disseminated cancer both untreated and previously treated received bialkylator chemotherapy, thiotepa, and cyclophosphamide and reinfusion of cryopreserved autologous bone marrow (ABMR). The cyclophosphamide dose was constant at 7.5 g/m2 over three days, while thiotepa was started at 1.8 mg/kg for three days in escalating dose by a modified Fibonacci schema to 7 mg/kg. The median time to recovery of more than 500 granulocytes and more than 50,000 platelets/microL was 18 and 27 days, respectively. Four patients died as a consequence of severe, overwhelming infections or progressive disease during their period of aplasia. Of the 18 evaluable patients, a complete response (CR) was achieved in three patients and a partial response (PR) in ten patients for an overall response rate of 72%. The median duration of response was 14 weeks. Other nonhematologic toxicities included nausea/vomiting, diarrhea, stomatitis, skin rash, and cardiomyopathy. The maximum tolerated dose (MTD) of thiotepa was 700 mg/m2 or 6 mg/kg for three doses. Although there are substantial toxicities associated with this regimen, high-dose thiotepa and cyclophosphamide produce high response rates in patients with disseminated cancer.

From January 1978 to May 1983, 41 patients with primary high-grade osteogenic osteosarcoma of a limb were treated with a combination of intensive chemotherapy and prophylactic lung irradiation (PLI) intercalated between the first two cycles of chemotherapy. The primary tumor was treated according to its size and location by amputation, resection, high-dose radiotherapy, and salvage amputation for a tumor progressing under radiotherapy. Two weeks after surgery or simultaneously with radiotherapy, a three-drug regimen (cycle A) consisting of mitomycin C on day 1, vincristine followed by a 6-hour infusion of methotrexate on day 2 was given. Folinic acid rescue was started 6 hours after the end of the methotrexate infusion. A PLI of 20 G was given from day 10 to 22. On day 28, a four-drug regimen (cycle B) combining doxorubicin on day 1, vincristine on day 2 and dacarbazine with cyclophosphamide on days 3 to 6 was administered. Thereafter, five additional cycles of A and B were administered provided that the absolute number of polymorphonuclear cells and platelets had recovered. When these values were not attained, treatment was delayed until recovery. After a mean follow-up of 60.6 months, 16 patients have developed distant metastases, associated in four cases with local recurrence. Sixteen patients have died: 15 with metastases, one with no evidence of disease (toxic death). The overall survival of the entire group is 66% and the continuously disease-free survival 58% at 5 years. Alopecia, nausea, vomiting, asthenia, anorexia, and infraclinical and reversible impairment of lung ventilatory function were universal. A noticeable hematologic toxicity also was seen. One toxic death occurred after a pulmonary infection. Two patients developed cardiomyopathy. A multiparametic analysis of prognostic factors shows the very significant influence of age on treatment outcome. The continuous disease-free survival among the 17 patients younger than 15 years is 41% compared to 79% in older patients. The prognostic influence of age was independent of other factors. The delay (for more than two cycles) of methotrexate administration was the second independent prognostic factor. These results raise the question of using different protocols of adjuvant chemotherapy for patients younger or older than 15 years in order to optimize the curability/toxicity ratio.

The safety issues relevant to treatment with encainide in patients with supraventricular arrhythmia were reviewed based on 349 patients enrolled in clinical trials in the United States and Europe. Although 20% of patients had a history of congestive heart failure, cardiomegaly, or cardiomyopathy at entry, there was no case of new or worsened heart failure. There were 5 cases (1.4%) of proarrhythmia in adults, reflecting a worsening of the arrhythmia being treated or of a coexisting ventricular arrhythmia. The profile of drug-related adverse effects was comparable to that previously reported, causing discontinuance in 6% of patients. The effects most often seen were dizziness, visual disturbance, headache, nausea and vertigo. Only 1 patient had clinically significant abnormal laboratory values, possibly reflecting hepatocellular injury in conjunction with viral hepatitis. Most responders received a daily dose of 75 to 200 mg/day, generally given in 3 divided doses. Encainide has a very favorable safety profile for use in the treatment of supraventricular arrhythmias.

We conducted a phase I and pharmacokinetic study of i.v. idarubicin, a new anthracycline analogue, in 42 evaluable children 1-19 years old. Twenty-seven had leukemia and 15 had various solid tumors. The drug was administered in escalating doses of 10 to 40 mg/m2/course in 3 equal fractions over 3 consecutive days at 14- to 21-day intervals. Myelosuppression and mucositis were the limiting toxicities for short-term administration. Nausea, vomiting, and elevation of liver enzymes and bilirubin were the other toxicities encountered. Peak toxicity occurred 2 weeks after drug administration with median recovery by day 24. All but 4 patients with solid tumors had prior anthracyclines. Mild cardiac function changes without clinical symptoms were observed in 17 of 35 patients measured by serial cardiac evaluations. In addition, there were 4 patients with congestive heart failure. On postmortem examination, 4 patients had changes consistent with anthracycline cardiomyopathy at a prior median total anthracycline dose of 175 mg/m2. The maximum tolerated dose for patients with solid tumors was 15 mg/m2 course in 3 divided doses. Patients with leukemia tolerated 30 mg/m2/course. Six of 15 evaluable patients with acute lymphoblastic leukemia who received greater than or equal to 30 mg/m2 idarubicin achieved a remission (M1 marrow status). The plasma clearance of idarubicin fits a 3-compartment model with a harmonic mean half-life of 2.4 min, 0.6 h, and 11.3 h for alpha, beta, and gamma phases, respectively. Idarubicinol was the only metabolite detected in the plasma and it accumulated during the 3 days of therapy. Idarubicin is similar to daunorubicin in pharmacology and toxicity. While the cardiotoxic dose still must be delineated, the complete remission achieved in multiple relapsed patients with acute lymphoblastic leukemia indicate promising activity in at least that disease.
