The laboratory data from 136 patients suffering from a mass outbreak of rubella were serially examined. Alteration of thrombocytopenia (38.7%), leukopenia (26.4%), increased LDH (94.3%), and increased GOT (32.4%) were observed during the early days of disease. Slightly later, increased GPT was noted in 48.5%. LDH isozymes may be grouped into two specific patterns: 1) an LDH3 dominant pattern appeared (90.4%) during the beginning days of the disease. 2) an LDH3 dominant pattern with LDH5 greater than LDH4 was detected one week later. It was concluded that the increase of LDH3 may have been induced by thrombocytopenia due to viral infection. The increase of LDH5 appears to result from liver damage. In conclusion, LDH isozyme findings are significant in the early diagnosis of liver damage in rubella.

Aztreonam was used successfully in 17 of 17 patients with orthopedic infections due to gram-negative bacilli (11, osteomyelitis; six, septic arthritis). Duration of treatment ranged from 14 to 55 days, and the period of follow-up was four to 18 months. Causative organisms included Pseudomonas aeruginosa, Serratia marcescens, Enterobacter gergoviae, Citrobacter diversus, Proteus mirabilis, and Enterobacter aerogenes. Aztreonam was well tolerated. The only definite reactions attributable to aztreonam were asymptomatic increases in serum aspartate aminotransferase (SGOT) and serum alanine aminotransferase (SGPT) in four patients; none of these reactions interfered with completion of therapy. Adverse reactions that were possibly attributable to aztreonam included rash (two patients), diarrhea (one patient), and leukopenia (one patient). All of these patients were receiving antibiotics active against gram-positive organisms in mixed infections in addition to aztreonam. Aztreonam is a promising new monobactam without significant toxicity. It has good activity against gram-negative aerobic bacteria, including P. aeruginosa, and is effective in the treatment of serious infections due to gram-negative aerobes.

We performed a phase I study of menogaril to determine if dosage reduction was required in patients with hepatic dysfunction and if the relationship between pharmacokinetics and leukopenia, previously defined in patients with normal hepatic and renal function, was altered. Eighteen patients received 27 courses of menogaril, of which 26 were evaluable for toxicity. Patient characteristics were median age, 63 years (range, 28-80 years), 14 male/4 female, and median Karnofsky performance status 80% (range, 60-100%). Prior therapy included none, five; chemotherapy only, seven; radiotherapy only, two; and chemotherapy and radiotherapy, four. Menogaril was administered as a 2-h.i.v. infusion every 28 days at 62.5 (one patient), 125 (eight patients), 187.5 (seven patients), and 250 mg/m2 (six patients), based on pretreatment serum bilirubin, aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. Patients also had indocyanine green and antipyrine clearances measured before menogaril treatment. Menogaril and metabolites were assayed by high performance liquid chromatography. Dose-limiting toxicity was leukopenia. WBC nadirs occurred between days 8 and 20 (median, 15). Three patients developed platelet nadirs below 100,000/microliters. Other toxicities included grade I nausea and vomiting in three patients and phlebitis at the site of drug infusion in six patients. Correlations were defined between pretreatment indocyanine green clearance and serum concentrations of alkaline phosphatase and total bilirubin. There were no correlations between pretreatment serum concentrations of bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, indocyanine green clearance or antipyrine and menogaril clearances. Menogaril pharmacokinetics in patients with elevated liver function tests was indistinguishable from that described in patients with normal liver function tests. There were excellent correlations between plasma area under the curve of menogaril and the percentage decreases in WBC and neutrophils. These were well described by two models previously used to study the same relationships in patients with normal hepatic and renal function. When compared to previous studies, patients with hepatic and renal dysfunction had a greater percentage decrease in WBC for any given area under the curve than did patients with normal hepatic and renal function. On the other hand, there was no difference in the relationship between percentage decrease in neutrophils and menogaril area under the curve in these two groups of patients.(ABSTRACT TRUNCATED AT 400 WORDS)

A clinical phase II study of recombinant human leukocyte interferon A (rIFN-alpha A, Ro 22-8181) for various skin malignant tumors was jointly conducted at nine medical institutes across the country in order to study its clinical effect and side effects. Patients received Ro 22-8181 alone in doses ranging from 3 X 10(6) U/day to 50 X 10(6) U/day either by intramuscular injection or by local injection. Good response was obtained in one (4.8%) of 21 patients treated by intramuscular injection and in 26 (72.2%) of 36 patients treated by local injection. The percentage of good responses achieved by local injection for individual diseases was 55.6% (5/9) for metastatic malignant skin melanoma, 100% (11/11) for cutaneous malignant lymphoma, 100% (5/5) for extramammary Paget's disease, 75% (3/4) for intraepidermal cancer and 50% (2/4) for metastatic skin cancer. Main side effects were fever, anorexia, general fatigue, chills, nausea and vomiting. Abnormal laboratory data included leukopenia, and elevation of GOT and GPT, although their incidence was lower with local injection than with intramuscular injection. Side effects were mostly improved by reduction of the dose or discontinuation of the treatment.

A phase II study of bronchial artery infusion of mitomycin C (MMC) was performed in 14 patients with non-small cell lung cancer (6 patients with adenocarcinoma, 6 patients with squamous cell carcinoma and 2 patients with large cell carcinoma). MMC at a dose of 20 mg was infused into the bronchial artery (total dose 20-60 mg, mean 27 mg). Among the 14 patients, one with adenocarcinoma of the lung showed partial response. The response rate for bronchial artery infusion of MMC was thus 7.1%. The toxic effects included anemia (35.7%), leukopenia (28.6%), thrombopenia (14.3%), elevation of GPT (14.3%), anorexia (14.3%), nausea (7.1%) and eruption (7.1%).

A pharmacokinetic and clinical study of ceftizoxime (CZX), a newly developed cephem antibiotic intended for parenteral use, was conducted in premature and newborn infants, and resulted in the following findings. 1. Pharmacokinetics (1) Average serum half-lives (T 1/2) following a one shot intravenous dose of 20 mg/kg of CZX to mature and premature newborn infants in age groups of 0-3, 4-7, 8-14, and 15-30 days were: 4.14, 3.01, 2.57, and 1.98 hours (for mature infants) and 5.26, 4.59, 3.71, and 2.64 hours (for premature infants), respectively, decreasing with ages in days of the infants. (2) Average T 1/2's after a one shot 10 mg/kg dose was similar to that after a 20 mg/kg dose. Serum concentrations of CZX were dose-dependent. (3) T 1/2 after 1-hour intravenous drip infusion revealed a same trend after one shot injection. (4) Urinary in the first approximately 6 hours recoveries following a 20 mg/kg one shot dose to mature and premature newborn infants were as follows: 35% (0-3 days old) and 45-55% (4 days old and older) in mature infants and 30% (0-3 days old) and 45% (4 days old and older) in premature infants. 2. Therapeutic effectiveness (1) The subjects examined were 112 newborn infants consisting of 83 with infections and 29 who received CZX for prophylaxis. The 83 infants had 86 cases of infections, which were classified as A, when the causative organisms were identified and as B, when the causative organisms were not identified. Rates of therapeutic effectiveness were 95.0% for group A and 95.7% for group B. Bacteriological effectiveness were studied on 41 strains isolated from group A, and were as high as 89.5% for Gram-positive organisms and 95.5% for Gram-negative organisms. The rate of successful prophylaxis for the 29 infants was 96.6%. (2) Side effects did not occur among the 120 newborn infants. Laboratory tests with abnormalities included leukopenia, neutropenia, eosinophilia, thrombocytosis and increased GOT or GPT. These pharmacodynamic and clinical findings have fully substantiated the satisfactory therapeutic usefulness of CZX in both the treatment and prevention of neonatal infections in the usual dose of 20 mg/kg, which is to be given b.i.d. for infants up to 3 days old; b.i.d. or t.i.d. for infants 4 to 7 days old, and t.i.d. or q.i.d. for infants 8 days old and older. The drug can be given in a daily dose as high as 120 mg/kg when infection is severe.

The phase II trial of natural interferon-alpha (HLBI) in treatment of adult T-cell leukemia was carried out as a cooperative study. Of the 24 cases which could be evaluated, 3 cases in crisis type and 5 cases in chronic type with lymphadenopathy and/or skin infiltration achieved PR, giving a response rate of 33.3%. The anti-tumor effect of HLBI for skin lesion could be assessed in 16 cases with skin infiltration, giving a response rate of 50.0% (5 CR and 3 PR) and demonstrating a high efficacy. Of the 31 eligible patients, side effects were recognised in 27 (87.1%). Major subjective and objective symptoms were fever (38.7%), fatigue (25.8%), anorexia (12.9%) and nausea (12.9%), and leukopenia (22.6%), granulocytopenia (38.7%), thrombocytopenia (38.7), elevation of GPT (12.9%) and GOT (12.9%) were observed.

The effect of postoperative immunochemotherapy with mitomycin C (MMC), 5-fluorouracil (5-FU) and OK-432 was evaluated as an adjuvant therapy after curative resection for gastric cancer. Immediately after surgery, patients were randomly allocated to the following three treatments: (A) chemotherapy with MMC and 5-FU (32 cases); (B) chemoimmunotherapy with MMC, 5-FU and OK-432 (33 cases); and (C) surgery alone as control (34 cases). There were no significant differences in the background factors influencing survival time among the groups, and there was no dose-distribution of chemotherapeutic agents between groups A and B. While the differences were not statistically significant, the survival rate and disease-free interval of group B were better than those of groups A or C. Side effects such as gastroenteric disorder, leukopenia (less than 3,000/mm3), thrombocytopenia (less than 7 X 10(4)/mm3) and increase of serum transaminase level (GPT greater than or equal to 100 units) were less frequently observed in group B than in group A. The results of the present study seemed to indicate that chemoimmunotherapy with OK-432 may be effective for surgical adjuvant therapy.

Cefuzonam (L-105, CZON), a new parenteral cephalosporin, was evaluated for its efficacy and safety in 22 children with bacterial infections (Table 1). The results obtained are summarized below. MICs of CZON to 26 strains of isolated organisms are shown in Table 2. MICs to all 14 strains of Haemophilus influenzae and 6 strains of Streptococcus pneumoniae were less than 0.05 microgram/ml. The MIC to 2 strains of Staphylococcus aureus was 0.39 microgram/ml and that to another was 0.78 microgram/ml. Two strains of Escherichia coli showed MICs of less than 0.05 and 0.10 microgram/ml, respectively. The MIC to 1 strain of Enterococcus faecalis was 6.25 micrograms/ml. The CZON was administered in 3 or 4 divided doses at a daily dosage ranging from 58.5 to 85.7 mg/kg by 30-minute drip infusion or intravenous injection to 22 patients (9 cases of pneumonia, 9 cases of tonsillitis, 2 cases of bronchitis, 1 case each of suppurative parotitis and acute pyelonephritis) and the following clinical results were obtained; excellent: 12 cases; good: 7 cases; fair: 3 cases. The overall efficacy rate was 86% (Table 4). Diarrhea was observed in four patients, and was resolved with or without discontinuation of the medication within a week. Anemia was noted in 2 cases. Leucopenia and neutropenia was observed in 1 case. There were a moderate rises in S-GOT and S-GPT activities in 1 patient (Table 4), and they necessitated the cessation of the CZON therapy. The S-GOT and S-GPT activities became normal after the drug treatment was stopped.(ABSTRACT TRUNCATED AT 250 WORDS)

CB3717 is a quinazoline antifolate whose cytotoxic activity is mediated by inhibition of thymidylate synthase (TS). A phase I clinical trial commenced in September 1981 and 99 patients have received 296 treatments. Doses were dissolved in 0.15 mol/L NaHCO3 (pH 9.0) at a concentration of 4 mg/mL infused over one hour or in a total volume of 1 L infused over 12 hours. Doses were repeated every 3 weeks. The starting dose of 140 mg/m2 was escalated to 600 mg/m2. Renal toxicity, detected by a decrease in the 51Cr EDTA clearance, was dose-related and occurred in seven of ten patients receiving greater than 450 mg/m2. Reversible hepatic toxicity often associated with malaise occurred in 223 of 288 assessable courses (77%). Fifty-nine courses (20%) were associated with increases in alanine transaminase (ALT) levels to greater than 2.5 times the upper limit of the normal laboratory range. Increases in alkaline phosphatase levels also occurred, but were less marked. The severity and prevalence of these elevations were unaffected by the duration of the infusion. A self-limiting rash appeared in 12 patients and a radiation recall reaction was seen in two. Leukopenia developed in 17 patients (WBC less than 3 X 10(9)/L), and thrombocytopenia occurred in six patients (platelets less than 100 X 10(9)/L). The mean leucocyte nadir occurred on day 10 and was followed by recovery at 11 to 19 days. Neither the incidence nor the severity of any of these latter toxicities was dose related. The maximum tolerated dose was in the region of 600 mg/m2 with renal toxicity being dose limiting, although the inter-patient variation did not allow a precise definition. Seventy-six patients were evaluable for response. Responses occurred at doses greater than or equal to 200 mg/m2 and were ovary, one complete response (CR), one partial response (PR), seven minor responses (MR) in 30 cases; breast, two PRs and one MR in eight cases; adenocarcinoma of the lung, one MR in 5 cases; mesothelioma, one PR in five cases; and colon, two MRs in four cases. CB3717 has activity in heavily pretreated patients. The recommended phase II dose for good-risk patients is 400 mg/m2 using the one-hour infusion schedule of administration.
