A total of 22 patients with acute pediatric infections was treated with rokitamycin (TMS-19-Q, RKM) dry syrup, a new macrolide antibiotic developed by Toyo Jozo Co., Ltd., Ohhito, Japan, to investigate its clinical efficacy. 1. A girl of an age 4 years 2 months (weighing 16.5 kg) was administered orally 10 mg/kg of RKM, and a boy of an age 8 years 7 months (weighing 24.5 kg), 15 mg/kg, and blood concentrations of RKM in these subjects were measured to investigate its absorption and excretion. Blood concentrations of the drug reached a peak of 0.84 microgram/ml in an hour after the administration in the girl, 0.72 microgram/ml in 30 minutes in the boy, with T1/2 of 0.86 and 1.82 hours, respectively. Their 6-hour cumulative urinary recovery rates were 2.79 and 2.13%, respectively. 2. A total of 20 patients was treated with RKM dry syrup. These patients included 3 with acute pharyngitis, one with acute tonsillitis, 4 with hemolytic streptococcal infections, 7 with acute bronchitis, 2 with pneumonia, another 2 with pertussis, and one with Campylobacter enteritis. The treatment was effective in 18 of them with a clinical efficacy of 90.0%. 3. Bacteriological responses to RKM dry syrup were as follows: eradication of pathogens in 5, pathogens decreased in 3, and no changes were observed in 3 of 12 patients from whom pathogens had been isolated prior to the treatment, thus the eradication rate was 45.5% with the exception of 1 patient whose bacteriological response was unknown.(ABSTRACT TRUNCATED AT 250 WORDS)

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)

Erythromycin, first introduced for clinical use 30 years ago, was found to be effective for the treatment of gram-positive bacterial infections. Emergence of resistance and the advent of penicillinase-resistant penicillins limited the use of erythromycin for serious staphylococcal infections; however, erythromycin remains among the drugs of choice for the treatment of acne, infections of the skin and soft tissues, streptococcal pharyngitis, bronchitis, pneumonitis, diphtheria, carriers of pertussis, and, when administered with a sulfonamide, otitis media. Erythromycin is the drug of choice for the empiric treatment of outpatients with pneumonitis. Erythromycin is also the drug of choice for the treatment of Legionella pneumonia and is effective therapy for Chlamydia infections. Other uses of erythromycin include prophylaxis for elective colon operations and treatment of Campylobacter enteritis, genitourinary infections, and some sexually transmitted diseases.

BRL 25000 granules, a formulation consisting of amoxicillin (AMPC) and clavulanic acid (CVA), was evaluated in the field of pediatrics. In a pharmacokinetic study, serum concentrations were determined in a patient after oral administration of BRL 25000 granules in the non-fasting state at a dose of 11.76 mg/kg. The serum levels of amoxicillin (AMPC) and clavulanic acid (CVA) 1 hour after administration were 7.76 micrograms/ml and 6.64 micrograms/ml, with biological half-lives of 0.86 hour and 0.88 hour respectively. The serum concentration profile at a dose of 31.58 mg/kg showed almost the same tendency as at 11.76 mg/kg, although the peak level and biological half-life of the serum concentrations were not obtained. These serum levels and their peak levels were considered reasonable compared with those obtained in adults at similar dose levels. In clinical studies, 34 patients were evaluated including 8 patients with acute pharyngitis or acute tonsillitis, 1 patient with acute bronchitis, 1 patient with bronchopneumonia, 23 patients with scarlet fever and 1 patient with pertussis. BRL 25000 granules were administered orally 3-4 times per day for 4-8 days to 2 patients at doses of 20 approximately less than 30 mg/kg/day, to 18 patients at doses of 30 approximately less than 40 mg/kg/day, to 11 patients at doses of 40 less than approximately 50 mg/kg/day, and to 3 patients at doses of 50-60 mg/kg/day. The clinical response was assessed excellent in 13 cases and good in 21 cases giving an overall clinical efficacy rate of 100% (34/34). The causative organisms were isolated in 17 cases and included 12 strains of Streptococcus group A, 2 S. pneumoniae, 3 H. influenzae and 1 H. parainfluenzae.(ABSTRACT TRUNCATED AT 250 WORDS)

The decline in infectious disease mortality in England and Wales beginning about 1880 has been attributed to improved nutrition, hygiene, and sanitation. Such an explanation does not adequately explain the lack of improvement in infant and diarrheal disease mortality before 1900 nor the abrupt subsequent decline. A hypothesis was proposed that the decline in fertility rate was a major cause of the decline in infant mortality by raising the median age at infection. The hypothesis could only be tested indirectly. A review of morbidity data demonstrates the importance of family characteristics on the median age at infection for measles, pertussis, and common respiratory illness. The association of parity with infectious disease mortality supports the hypothesis. A method was developed for estimating the change in birth order distribution resulting from declining fertility. Using 1949-1950 data, it was shown that declining fertility could account for at least a 24% decline in postneonatal mortality due to bronchitis and pneumonia. Age-specific measles mortality rates are consistent, with an increase in age at infection. Declining fertility appears to have played a major role in the decline in infectious disease mortality in England and Wales by increasing the median age at infection.

The pharmacokinetics of ceftriaxone (Ro 13-9904, CTRX) was studied in 14 children receiving a dose of 10, 20 mg/kg or 1 g as a intravenous bolus. The mean half-lives of CTRX were 4.5, 6.3 +/- 0.5 and 5.2 +/- 0.7 hours, respectively, while the urinary recovery rates up to 12 hours were 51.7, 48.6 and 48.9%. Forty-one patients, aged 2 months to 10 years, were treated with an intravenous dosage of 10 to 58 mg/kg CTRX every 12 hours for 2 to 29 days. The diseases consisted of upper respiratory tract infections (4), bronchitis (7), pneumonia (18), pyothorax (2), urinary tract infections (4), pertussis (4), meningitis (1) and endocarditis (1). Clinical cures were achieved in 38 cases, overall clinical response rate being 92.7%. No serious side effects were observed, although mild diarrhea was seen in 2 cases.

Studies on T-1982 (cefbuperazone), a new cephamycin antibiotic, were carried out in the field of pediatrics, and the following results were obtained. 1. Peak MIC of T-1982 against S. pyogenes (group A) lately isolated was 0.39 micrograms/ml, and the drug was active even against highly resistant strains of macrolides, lincomycin, tetracycline and chloramphenicol. 2. Peak MICs of T-1982 were 0.78 microgram/ml against B. pertussis, 0.2 microgram/ml against E. coli and less than or equal to 0.05 microgram/ml against K. oxytoca, and the drug was also active against ampicillin-resistant bacteria. 3. Serum levels and urinary excretions of T-1982 were investigated in 6 cases. When given at a dose of 20-28 mg/kg by 1 hour intravenous drip infusion, serum concentrations of T-1982 attained the peak level of 63.5-75.9 micrograms/ml at the end of administration and sustained the level of 0.9-2.6 micrograms/ml at 6 hours, the serum half-life (T 1/2) ranging 70-82 minutes. Approximately 20-72% of the dose were excreted in the active form into urine within 6 hours. 4. Twenty-seven cases of acute pediatric infections were treated with T-1982 mainly by intravenous drip infusion, and satisfactory clinical results were obtained in all the cases of angina lacunaris, bronchitis, bronchopneumonia, pertussis, sepsis caused by Serratia and acute urinary tract infections caused by ampicillin-resistant E. coli. The efficacy rate was 96.3%. In this study the drug was administered chiefly at a daily dose of 50-70 mg/kg 2-3 times a day for 2-12 days. 5. Gram-positive cocci (S. aureus, S. pneumoniae, S. pyogenes) and Gram-negative rods (H. influenzae, H. parainfluenzae P. vulgaris, B. pertussis, S. marcescens, E. coli) were eradicated by the treatment with T-1982. 6. No noticeable side effects were observed, except for temporary increase of eosinophil in 2 cases and slight elevation of GOT in 1 case.

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.
