An intravenous preparation of doxycycline (DOTC, Vibramycin 'Pfizer'), a long-lasting tetracycline, was administered mainly by drip infusion for a series of study in the pediatrics field, and the results were as follows: 1) DOTC (100 mg) was dissolved in a 100 ml of glucose solution and 2--3 mg/kg was administered intravenously. When the total infusion time was adjusted between one to two hours, the peak serum level of DOTC was seen at the end of infusion in each case. The serum level in a two-hour infusion time, however, the serum level was delectable for a long period of time: the serum level after 10 hours was 0.82--1.23 micrograms/ml. Above results suggest that DOTC intravenous should be given in a two-hour infusion twice a day for applicable infections in the pediatrics field. 2) Urine excretion of DOTC was about a half (50%) of the administered dosage. 3) DOTC was given mostly at about 3--5 mg/kg per day (twice a day) infusion to 25 children with five infections, viz. acute angina lacunaris, acute bronchitis, bronchopneumonia, Mycoplasma pneumonia and acute urinary tract infections. A clinical improvement seemed attributable to DOTC was clearly observed in 23 out of 25 patients (92%). 4). DOTC infusion was also effective for Mycoplasma meningoencephalitis, severe Mycoplasma pneumonia associated with pleuritis, bronchitis and bronchopneumonia with a lot of Staphylococcus aureus identified in the sputum medium, acute urinary tract infections caused by E. coli. 5) Before and ten days after DOTC infusion, laboratory tests for liver and renal functions and blood were performed. No noticeable abnormalities were found except one case with transient GOT and GPT elevations. Above summary was presented at the 26th annual meeting of Japan Society of Chemotherapy in June 1978.

One hundred and eleven children with Mycoplasma pneumonia infection were studied. Their mean age was 6.2 +/- 3.1 years. The two commonest symptoms were cough (98%) and fever (95%). Only 23% of children had cough of greater than one week's duration. Ninety one per cent had positive chest signs. Radiological abnormalities were seen in 95% of chest x-ray. Complications included dermatological (10%), pleural effusion (5%), neurological disorder (3%), septicaemia (1%), bronchiectasis (1%). Two children with Down's Syndrome died. A rare case of Mycoplasma bronchitis with Reye's Syndrome was observed.

We made an open, noncomparative evaluation of ofloxacin, 400 mg orally bid for 10 days, in 98 subjects with community-acquired pneumonia or pathogen-confirmed bronchitis. Thirty-nine (40%) of the subjects were treated in the hospital and 59 (60%) were treated as outpatients. The mean age of those treated was 56.2 years; 73 (74%) of the subjects either were more than 60 years old or had a history of chronic obstructive pulmonary disease, or both. There were 95 organisms initially isolated in sputum, aspirate, or lavage fluid; all were susceptible to ofloxacin, and none acquired resistance during therapy. Haemophilus influenzae was the most common pathogen (19 isolates), followed by Streptococcus pneumoniae (18) and Staphylococcus aureus (10). Clinical responses included cure in 70 patients (71%), improvement in 26 (27%), and failure in two (2%). After 10 days of therapy, pathogens persisted in two cases; in one case, Streptococcus salivarius was isolated, though it remained susceptible to ofloxacin, and in the other, Klebsiella pneumoniae was accompanied by superinfection due to a resistant strain of Serratia marcescens. We included in this study three confirmed cases of atypical pneumonia successfully treated with ofloxacin, two of them due to Mycoplasma pneumonia and one to Legionella pneumophila. Ofloxacin was well tolerated. Our data indicate that ofloxacin is effective and safe as specific and empiric treatment for many lower respiratory tract infections.

Clarithromycin (TE-031, A-56268) is a new 14-membered ring macrolide antibiotic developed by Taisho Pharmaceutical Co., Ltd. TE-031 has a methoxy group at position 6 in its structure. In the present study, we carried out laboratory and clinical investigations on TE-031 in the field of pediatrics. The obtained results are summarized as follows. The antibacterial activity of TE-031 was investigated against 16 clinically isolated strains of Streptococcus pyogenes, Staphylococcus aureus, Haemophilus influenzae, Bordetella pertussis and Campylobacter jejuni. TE-031 showed antibacterial activity comparable to erythromycin. The pattern of changes in TE-031 concentrations in the blood after administration was investigated. In subjects administered the granular preparation of TE-031, Cmax values were 0.64 micrograms/ml in 1 subject given a 5 mg/kg dosage, and 5.94 and 9.02 micrograms/ml in 2 subjects administered with 10 mg/kg. The tablet form of TE-031 was administered to 3 subjects at 5 mg/kg, and Cmax values were 2.09-3.92 micrograms/ml, while T 1/2 values were in a range of 2.9-3.8 hours. When drug concentrations in the urine were investigated, it was found that 6-hour recovery rates were 9.9% (dose: 5 mg/kg) and 53.4% (dose: 10 mg/kg) in the subjects administered the granular form, whereas recovery rates averaged 36.8% in the tablet-administered subjects. In the clinical trial, TE-031 was administered in 2-3 doses/day for 2-18 days. In cases given the granular form, dosages were 12-38 mg/kg/day, while tablets were administered at 12-29 mg/kg/day. The overall clinical efficacy rate was 92.8%, i.e., the drug was effective in 64 of 69 patients. TE-031 was ineffective in 1 case of otitis media, but efficacious in 10 of 10 (100%) cases of upper respiratory infection, 15 of 18 (83.3%) cases of bronchitis and pneumonia, 5 of 6 (83.3%) cases of pertussis, 13 of 13 (100%) cases of mycoplasmal pneumonia, 4 of 4 (100%) cases of Chlamydia psittaci pneumonia, 16 of 16 (100%) cases of gastroenteritis (including 15 cases of Campylobacter gastroenteritis), and 1 (100%) case of impetigo. In bacteriological studies conducted on the patients, the overall elimination rate was 93.1%, i.e., bacterial elimination was obtained in 27 of 29 cases. TE-031 showed especially good bacteriological efficacy (100%) against C. jejuni and B. pertussis, which were eliminated from all of 15 and 2 cases examined, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

We have carried out laboratory and clinical studies on clarithromycin (TE-031, A-56268). The results are summarized as follows. Serum and urinary concentrations of TE-031 were determined in 5 children with ages between 6 and 11 years given single oral doses of 5, 6.7, 10 and 15 mg/kg. Serum concentrations peaked at 1 hour after administration of 5, 6.7 and 15 mg/kg, and respective peak values were 1.98 micrograms/ml, 2.21 micrograms/ml and 5.58 micrograms/ml. Biological half-lives for the drug at 5, 6.7 and 15 mg/kg dose were 2.99 hours, 2.08 hours and 2.09 hours, respectively. Mean serum concentrations peaked at 2 hours after administration of 10 mg/kg, and peak values were 3.91 +/- 1.64 micrograms/ml. Biological half-lives were 3.00 +/- 0.58 hours. The 6-hour urinary recovery rates ranged from 22.7% to 23.8% after administration of 10 mg/kg, and the 6-hour urinary recoveries were 30.1%, 20.5% and 39.1% after administration of 5 mg/kg, 6.7 mg/kg and 15 mg/kg, respectively. Therapeutic responses were recorded as excellent or good in 35(89.7%) of the children, comprising 5 with tonsillitis, 3 with pharyngitis, 7 with bronchitis, 5 with pneumonia, 15 with Mycoplasma pneumonia, 1 with whooping cough and 3 with Campylobacter enteritis. The microbiological effectiveness of TE-031 on identified pathogens comprising 2 strains of Streptococcus pneumoniae, 5 strains of Haemophilus influenzae, 2 strains of Haemophilus parainfluenzae, 5 strains of Mycoplasma pneumoniae and Campylobacter spp. was satisfactory as evidenced by an eradication rate of 82.4%. No significant side effect due to the drug was observed in any cases. In conclusion, TE-031 was found to be efficacious and safe for the treatment of bacterial infections in children.

A newly developed macrolide clarithromycin (TE-031, A-56268), with antibacterial spectrum and antibacterial activity nearly equal to those of erythromycin (EM), shows beneficial characteristics such as a higher blood level, higher recovery rate in urine, and better penetration into each tissue than conventional macrolides (MLs). TE-031 has been studied in adults against various infections and proved to be useful. The present paper describes the results of a study in children to examine the usefulness of TE-031 granules and tablets with a potency of 50 mg. TE-031 granules were administered to 132 children with ages from 6 months to 13 years and 10 months. Excluded from the evaluation were 12 cases in which clinical effects were deemed unevaluable. The evaluable subjects consisted of 1 case with pharyngitis, 3 with tonsillitis, 9 with acute bronchitis, 19 with pneumonia, 19 with mycoplasmal pneumonia, 2 with scarlet fever, 20 with Campylobacter enteritis, 11 with impetigo, 2 with subcutaneous abscess, 18 with primary atypical pneumonia and 16 with acute enteritis of unidentified pathogens; a total of 120 subjects. An average daily dose of TE-031 was 25.9 mg/kg, divided into 3 doses except 1 case with 2 daily doses and lengths of the treatment averaged 7 days. TE-031 tablets each containing 50 mg potency, were administered to 49 subjects with ages from 3 year and a month to 14 years consisting of 8 cases with pharyngitis, 1 with tonsillitis, 1 with acute bronchitis, 4 with pneumonia, 14 with mycoplasmal pneumonia, 4 with scarlet fever, 5 with Campylobacter enteritis, 7 with impetigo, 1 with atypical pneumonia, 1 with Salmonella gastroenteritis and 3 with acute enteritis caused by unidentified pathogens, at an average daily dose of 13.5 mg/kg dived into 2-4 doses (2 doses/day for 12 cases, 3 doses for 32, 4 doses for 5) for 7 days on the average. In addition to examine the clinical and bacteriological effects of the 2 dosage forms of TE-031, minimum inhibitory concentrations (MICs) were determined for 9 antibiotics consisting of 5 MLs including TE-031, EM, josamycin (JM), midecamycin acetate (MDM acetate), and rokitamycin (RKM), 3 penicillins including ampicillin (ABPC), methicillin, cloxacillin and 1 cephem antibiotic, cefaclor (CCL), against 29 strains consisting of 12 strains of Staphylococcus aureus, 7 of Streptococcus pyogenes, 2 of Streptococcus pneumonia 2 of Haemophilus influenzae and 6 of Campylobacter jejuni, out of 71 strains of pathogens or possible pathogens that had been isolated from the cases given TE-031.
