We studied clinical effects of meropenem (MEPM, SM-7338), a newly developed parenteral carbapenem beta-lactam drug, and following results were obtained. The patients were administered with 16-20 mg/kg of MEPM every 8 hours using 1 hour drip infusion. 1. Clinical effects of MEPM were studied in 10 children with various infectious diseases: 1 with acute bronchitis, and 2 each with acute tonsillitis, acute bronchopneumonia, acute pneumonia, acute urinary infection, and 1 with pertussis pneumonia. The case of pertussis pneumonia later developed bronchiolitis obliterans, hence a steroid and gamma-globulin were used. This case was excluded from the clinical evaluation. The efficacy rate was 100% (9/9), and the bacteriological eradication rate was 100% (6/6). 2. No side effects were noted. Clinical laboratory test values were investigated in 10 patients. There was a case of abnormal laboratory test findings with mild elevations of liver functions such as GOT, GPT, and gamma-GTP. These abnormalities disappeared in 1 week after the end of therapy.

We have isolated 120 mutant strains producing pertussis toxin (PT) cross reacting materials (CRMs) from B. pertussis, strain Tohama, phase I by nitrosoguanidine treatment. Strains producing higher PT tend to show higher virulence in mice. No direct correlation between the virulence and other factors, such as filamentous hemagglutinin, adenylate cyclase or dermonecrotic heat labile toxin, was found. Most CRMs were less reactive to the anti-S1 monoclonal antibody, 1B7. When the PT CRMs produced by strains 69D, 74E or 79G, which were less or non-toxic, were mixed with A protomer purified from native PT, the PT activity assayed by clustering of CHO-cells increased significantly, but not when they were mixed with B oligomer. These CRMs may be composed of defective S1 and intact S2, S3, S4 and S5. Molecular sizes of PT CRMs outside and inside the cells were analysed by sucrose density gradient centrifugation. The sizes of the CRMs were in the range of 10K to 210K, but the biological activity of PT was detected at only the same molecular size, 106 K, as native PT. The majority of the CRM was released into culture medium if all five subunits were assembled; otherwise they accumulated inside the cell without completion of assembly to form the hexamer in the PT-form. One of the non-toxic mutants named 79G showed one point mutation from G to A at the 730th base from the Eco R1 site of the PT gene. Replacement of Cys-41 with Tyr-41 in S1 must have resulted from this mutation. 79G PT composed of S234 (5) was accumulated both inside and outside the cells because the mutant S1 could not form the disulfide bond in the molecule to form the hexamer with the B oligomer, and also S1 must be degraded because of its instability in the cells. Nevertheless 79 GPT showed high immunoprotectivity in mice by active or passive immunization against ic or aerosol challenge with B. pertussis, strain 18323, respectively. It may have a proper conformational structure for protective immunogenicity and could become a good candidate strain for production of a safer and effective pertussis vaccine in the future.

A new oral macrolide, clarithromycin (TE-031, A-56268), was evaluated for its safety, efficacy and pharmacokinetics in 33 children. TE-031 was effective in all cases of mycoplasmal pneumonia, pneumococcal pneumonia, streptococcal pharyngitis, pertussis and Campylobacter gastroenteritis. The pharmacokinetic availability of TE-031 granule and tablets was much better than the older macrolides; serum half-lives of TE-031 averaged 3.2 +/- 0.25 hours (for the granule preparation). No clinical adverse reaction was encountered, but cases of transient mild elevation of the serum GPT (2 cases) and eosinophilia (2 cases) were encountered. From these preliminary data, TE-031 seems to have a place in the treatment of pediatric infectious diseases.

We studied the absorption and excretion as well as the clinical effect of rokitamycin (RKM, TMS-19-Q) dry syrup. The results we found are summarized as follows: 1. When 3 pediatric patients were medicated orally with a single dose of 10 mg/kg of the drug, its peak concentrations of 0.75 and 0.51 microgram/ml appeared in the blood in 30 minutes after administration in 2 patients, and of 0.21 microgram/ml in 1 hour in the other patient. At 4 hours after administration, its concentration in the blood was 0.07-0.08 microgram/ml in all of the patient, and at 6 hours, it was undetectable. T1/2 values were 1.05-2.08 hours. First 6-hour urinary recovery rates of the drug in the first 2 patients were 1.52 and 1.11%, respectively. 2. Twenty-four patients with 25 diseases were medicated with 7.14-12.5 mg/kg of the drug 3-4 times daily for 4-10 days. The patients consisted of 12 with tonsillitis, 7 with bronchitis, 3 with colitis, one each with Haemophilus influenzae pneumonia, mycoplasmal pneumonia, and pertussis. Clinical responses to the treatment were excellent in 7, good in 13, and poor in 5, with an efficacy rate of 80.0%. Bacteriologically, of 17 isolates whose changes were followed, 8 were eradicated, 1 decreased, and 8 remained unchanged, with an eradication rate of 47.1%. 3. No adverse reactions to the drug were observed in any of these patients, while abnormal laboratory test values observed were slight eosinophilia and also slight elevations of S-GOT and S-GPT in one of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical evaluation of ceftizoxime suppository (CZX-S), a new antibiotic rectal suppository, was performed in 5 cases with bacterial infections in pediatric field (2 with acute bronchitis, 1 with acute tonsillitis, UTI and pertussis, respectively) and the following results were obtained; Blood levels of CZX at 10-20 minutes after administration of CZX-S at a dose of 10.0-26.3 mg/kg in 5 cases were 3.26-23.3 micrograms/ml and the urinary excretion rates within 6 hours were 15.2, 60.1, 60.2% in 3 of 5 cases measured respectively. Clinical effects were excellent in 3 and good in 2 cases. Slight elevation of GOT and GPT was observed in 1 case. No other side effects were observed. The patients' tolerability against rectal suppository was good. From the above results, we concluded that CZX-S is useful for treating the pediatric patients with various infections.

Ceftazidime (CAZ), developed by Glaxo U.K., was used in pediatric patients with acute infections, and the following results were obtained. The mean blood concentrations of CAZ in 2 children were 142, 70.3, 46.9, 35.7, 16.2, 5.82 and 2.36 micrograms/ml at 5, 15, 30 minutes, 1, 2, 4 and 6 hours, respectively, after start of 5 minutes' intravenous injection of 20 mg/kg, with the half-life of 1.25 hours. CAZ was administered to 19 pediatric patients with acute infections. Out of them, 15 patients, i.e., 3 with acute tonsillitis, 1 with acute bronchitis, 5 with bronchopneumonia, 2 with pertussis accompanying pneumonia, 2 with Salmonella enteritis, 1 with impetigo staphylogenes and 1 with subdural abscess, were adopted for the evaluation, and the other 4 were excluded from the evaluation because of inadequate indications. The efficacy rate in these 15 cases was 93.3%. The doses used in 14 out of the evaluated 15 cases ranged from 31 to 50 mg/kg/day, the frequency of dosing was twice daily in 8 cases and 3 times daily in 7 cases. One shot intravenous injection was used in 6 cases, intravenous drip infusion in 8, and combination of these, in 1 case. The duration of treatment was 2 days in 3 cases, 3 days in 3, 4 days in 4, and 5 days in 3 cases. Patients with severe infections were generally given large doses for long-term. No clinical adverse event was observed in any case. In laboratory examinations, slight elevation of S-GPT alone was observed in 1 case. From the above results, CAZ was considered to be a highly useful drug in the field of pediatrics.

A new semisynthetic 1-oxa-beta-lactam derivative, 6059-S, was evaluated for its safety and efficacy in children. Twenty-five patients were treated with 10 to 274 mg/kg per day of 6059-S by intravenous administrations. The diagnosis of the patients were acute pharyngitis (2), acute bronchitis (2), pneumonia (4), pertussis (4), acute enterocolitis (2), recurrent urinary tract infection (2), suspected septicemia (3), and acute purulent meningitis (1); and the remaining 5 patients were considered to have nonbacterial infections. The pathogens recovered were Streptococcus pneumoniae (1), Haemophilus influenzae (4), Haemophilus parainfluenzae (1), Enterobacter cloacae (1), Enterobacter aerogenes (1), Proteus morganii (1), Psuedomonas aeruginosa (2) and Salmonella typhimurium (1). All the patients of bacterial infections were cured after the 6059-S therapy. However, Pseudomonas aeruginosa and Salmonella typhimurium were not eradicated after the 6059-S therapy, and the rate of bacterial disappearance was 75%. Diarrhea (3), precordial pain (2, only in cases with high-dose therapy), transient elevation of GOT and GPT (2), and transient eosinophilia (2) were found to be associated with the 6059-S therapy. However, no severe adverse reactions were encountered. Half life of the serum 6059-S level was 1.34 +/- 0.16 hours. CSF concentrations in a case with Haemophilus influenzae meningitis ranged 4.0 to 9.7 mcg/ml after an intravenous injection of 34.3 to 75 mg/kg of 6059-S. From the present study, 6059-S appears to be a safe and effective antibiotic when used in children with susceptible bacterial infections. It remains to be further determined whether 6059-S is superior to ABPC in the treatment of Haemophilus influenzae meningitis.

The response of adenylate cyclase to GTP and to dopamine (DA) was investigated in striatal membranes from desipramine (DMI)-treated rats (10 mg/kg, b.i.d., for 5 days). GPT exerted the same biphasic effect on basal and DA-stimulated enzyme activity in membranes from DMI-treated rats as on saline-treated rats. Rats were injected intraventricularly once with islet activating protein (IAP), pertussis toxin, and given extended treatment with DMI in order to study the effects on the inhibitory GTP-binding protein (Gi). Gi loses its function as a signal transducer on being ADP-ribosylated selectively by the IAP. D2 inhibition of adenylate cyclase by DA was attenuated by the IAP treatment in both DMI-and saline-treated rats; peak levels of DA plus GTP stimulation shifted from 1 microM to 100 microM GTP. D1 stimulation of adenylate cyclase by DA was also attenuated by the IAP in the DMI-treated rats. Since long-term treatment with DMI (15 mg/kg, once a day, for 3 weeks) resulted in suppression of D1 stimulation similar to that seen in the present findings, uncoupling between D2 receptors and Gi due to IAP treatment might accelerate DMI-induced adaptive changes of dual control of adenylate cyclase system by DA.

1. SY5555 dry syrup (powder which is dissolved before use) was administered to 25 patients with bacterial infections (6 cases of bronchitis, 2 cases of bronchopneumonia, 1 case of pertussis, 3 cases of scarlet fever, 5 cases of tonsillitis, 3 cases of urinary tract infections, 2 cases of staphylococcal scalded skin syndrome, 1 case of impetigo, 2 cases of purulent lymphadenitis). 2. Clinical efficacies were excellent in 11 patients and good in 13, poor in 1 with an efficacy rate of 96.0%. As pathogenic organisms, 15 strains were identified and 14 of them were eradicated with eradication rate of 93.3%. 3. No side effects were observed. As for abnormal laboratory test results increase in eosinophiles in 2 cases, decrease in filamented neutrophiles in 1 case, elevation of GOT and GTP in 1 case and elevation of GPT and gamma-GTP were observed. 4. There was no rejection incidence of the drug during the therapy. From the above results, we consider SY5555 in dry syrup form to be a useful and safe drug in the treatment of various bacterial infections in pediatric patients.

Pharmacokinetic and clinical studies on S-1108, a new oral cephem antibiotic, were performed in pediatric infections and the following results were obtained. 1. Pharmacokinetics studies Pharmacokinetics of S-1108 was studied in 4 children (3 y 7 m-11 y 1 m) using doses of 2 mg/kg (n = 2) and 4 mg/kg (n = 2). The average peak plasma level was 0.88 microgram/ml at 2 hours after administration of 2 mg/kg and 2.00 micrograms/ml at 3 hours after administration of 4 mg/kg, and plasma half-lives were 1.45 and 0.96 hours, respectively. Average cumulative urinary recovery rates at 0-6 hours were 30.0 and 34.8%, respectively. 2. Clinical studies S-1108 was administered to 32 patients with various infectious diseases (6 with acute tonsillitis, 2 each with pertussis and acute bronchitis, 3 with pneumonia, 4 with scarlet fever, 5 with impetigo contagiosa, 6 with acute urinary infection and 1 each with subcutaneous abscess, impetigo, vulvitis and urethritis) at daily doses between 6-12 mg/kg/day, t.i.d., for 5-12 days. Clinical responses were excellent in 17 patients, good in 13, and poor in 2, and the efficacy rate was 93.8%. Bacteria were identified and 33 strains of 12 species were found. The eradication rate was 93.9%. No side effects were observed in 43 patients. Abnormal laboratory test values were observed in 2 patients, 1 with elevation of eosin. and the other with elevations of GOT and GPT. The results suggest that S-1108 may be a very useful and safe drug for the treatment of pediatric infections.
