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.

Clarithromycin (TE-031, A-56268), a new macrolide antibiotic agent, was evaluated bacteriologically and clinically for its efficacy and safety in pediatrics by a study group organized with pediatricians from all over the country. A summary of the results of the evaluation is as follows. 1. Absorption and excretion Pharmacokinetics of TE-031 was examined by single oral administration of 10% granules and 50 mg tablets at doses of 1, 5, 10 and 15 mg/kg. There were no significant differences between 10% granules and 50 mg tablets, and between administrations before and after meal. Peaks and half-life periods of blood level of TE-031 given once at doses of 5, 10 and 15 mg/kg (10% granules) before meal were 1.58, 4.37 and 3.79 micrograms/ml, and 2.53, 3.17 and 2.20 hours, respectively, and the urinary excretion in 6 hours after the administration were about 20-30%. 2. Antibacterial effects TE-031 was proved to have excellent antibacterial effect, i.e., inhibiting growth over 80% of strains of Streptococcus pneumoniae and Streptococcus pyogenes at 0.10 micrograms/ml, Branhamella catarrhalis at 0.39 micrograms/ml, and Campylobacter jejuni at 0.78 micrograms/ml. Against Staphylococcus aureus, TE-031 showed very similar activity spectrum to EM, and EM resistant strains were also resistant to TE-031. 3. Clinical results A total of 764 cases was studied. Clinical effects of TE-031 were evaluated in 717 cases out of the 764, excluding drop-outs and cases which did not meet specified protocols. Clinically, efficacies of TE-031 were "excellent" in 265 cases and "good" in 161 cases out of 453 cases of Group A in which causal agents were identified, with an efficacy rate of 94.0%, and out of 264 cases of Group B in which pathogens were not detected, clinical effects of TE-031 were "excellent" in 115 cases and "good" in 124 cases, with an efficacy rate of 90.5%. In terms of clinical effects of TE-031 classified by diseases when Group A and B were combined, efficacy rates were 91.6% for upper respiratory tract infection (217/237), 90.0% for bacterial pneumonia (108/120), 97.4% for Mycoplasma pneumonia (111/114), 100% for Chlamydia pneumonia (4/4), 85.0% for pertussis (34/40), 100% for scarlet fever (16/16), 83.9% for skin and soft tissue infection (26/31), and 98.9% for Campylobacter enteritis (87/88).(ABSTRACT TRUNCATED AT 400 WORDS)

The usefulness of sulbactam/ampicillin (SBT/ABPC) in the treatment of pediatric infections was evaluated. 1. Twenty pediatric patients with infection were treated with SBT/ABPC and an intravenous dosage of 27.8-47.4 mg/kg, 3 to 4 times a day. Clinical efficacies in 18 patients excluding 2 patients of Mycoplasma pneumonia (9 cases of pneumonia, 6 urinary tract infection, 1 tonsillitis, 1 maxillary sinusitis and 1 osteomyelitis) were judged to be excellent in 13 patients and good in 5. There was no case of failure. 2. Bacteriological efficacies against 16 strains (1 Staphylococcus aureus, 3 Enterococcus faecalis, 4 Haemophilus influenzae, 2 Haemophilus parainfluenzae, 5 Escherichia coli and 1 Serratia sp.) isolated from 13 of the 18 patients were rated as "eradicated" for 13 strains, "decreased" for 1 and "unchanged" for 2 with an eradication rate of 81.3%. Of 13 strains eradicated, 3 were those with high beta-lactamase productivity. 3. Rash as a side effect developed in 1 patient and eosinophilia and elevated GOT and GPT were observed in 7 patients but none of them were serious. 4. Blood levels of the drug following an intravenous dose of 30 mg/kg were determined in 2 pediatric patients. Blood levels of SBT and ABPC at 30 minutes after intravenous administration were 19.0 and 29.2 micrograms/ml in one patient and 21.0 and 31.6 micrograms/ml in another, respectively, and those at 4 hours were 0.48 and 0.62 microgram/ml in one patient and 0.59 and 0.89 microgram/ml in another, respectively. The half-lives of SBT were 0.67 and 0.70 hour and those of ABPC were 0.64 and 0.69 hour in the 2 patients, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Cefodizime (THR-221, CDZM), a newly developed injectable cephem antibiotic, was injected intravenously to 13 cases of pediatric infections. Patients received the drug at a dose level of approximately 20 mg/kg x 3 times daily. The results obtained are summarized as follows. 1. Clinical efficacy was excellent in 4 patients, good in 6 and poor in 0 for 10 cases (2 phlegmon, 1 periproctal abscess, 5 pneumonia and 2 bronchitis) except 3 Mycoplasma pneumonia. 2. Three strains of pathogens were followed for their changes (Streptococcus pyogenes in 1 phlegmon, Klebsiella pneumoniae in periproctal abscess and Haemophilus influenzae in 1 bronchitis) and they were found to have been eliminated. 3. No adverse reactions occurred. Abnormal changes in laboratory test data found were 2 cases of eosinophilia, 1 cash each of increased GOT and GPT, and thrombocytosis, but none of them was severe.

It is sometimes difficult to clinically diagnose mycoplasma pneumonia at an early stage before the rise of titer of antibody to Mycoplasma pneumoniae. Mycoplasma pneumonia may be related with T-lymphocyte activity, and its inflammatory process is different from that of bacterial pneumonia. Adenosine deaminase (ADA) activity is a predominant T-lymphocyte enzyme, and its plasma activity is high in diseases in which cellular immunity is stimulated. In this study, we have investigated 31 cases with pneumonia (11 cases of mycoplasma pneumonia and 20 cases of bacterial pneumonia) within 10 days after onset to evaluate the usefulness of ADA measurement in the diagnosis of mycoplasma pneumonia. Serum ADA activity in the group of mycoplasma pneumonia was 32.1 +/- 12.0 U/l (63.9-18.8 U/l), that of non-mycoplasma pneumonia 12.5 +/- 3.3 (4.6-18.6) U/l, and that of normal control 14.0 +/- 3.4 (6.3-19.3) U/l. ADA activity of the group of mycoplasma pneumonia was significantly higher than those of non-mycoplasma pneumonia and normal control (p less than 0.001). This results suggest that serum ADA activity in patients with acute pneumonia may be useful for the early diagnosis of mycoplasma pneumonia.

The bacteriological study of sputa, nasopharyngeal smears and bronchial washings taken from pneumonia patients has shown that the leading etiological agent was Streptococcus pneumoniae isolated in the diagnostic titre (10(7) bacteria per ml) in 78.1% of the cases. Staphylococcus aureus, Haemophilus influenzae, enterobacteria and yeast-like fungi have been found to play an insignificant role in the etiology of acute pneumonia (2.5 +/- +/- 0.9%). The results of the serological diagnosis by means of the complement fixation test have revealed that, alongside S. pneumoniae, the following infective agents are of etiological importance in cases of acute pneumonia: respiratory viruses (more than 50%), Mycoplasma pneumonia (10%), Chlamydia psittaci (6.4%) and Legionella pneumophila (3.8%). The study has first revealed that, under the conditions of Alma-Ata, serotypes 19, 23, 8 and 4 prevail among circulating pneumococci. This study has also shown that the use of M. pneumoniae antibody erythrocyte diagnosticum enhances the detection rate of mycoplasma infections in pneumonia patients.

Rokitamycin (RKM), a newly developed macrolide antibiotic with a 16-membered ring, dissolves well under acidic conditions. It has been improved over other macrolides to minimize individual variations in its absorbability. We measured, using the GA-test, variations in gastric acidities of 43 children with ages between 1 to 14 years, and investigated the relationship between gastric acidities and pharmacokinetic values. Also activities (expressed in MICs) of antimicrobial agents were studied against clinically isolated 229 bacterial strains using an inoculum size of 10(6) cells/ml. Tested organisms included Streptococcus pyogenes (77 strains), Streptococcus agalactiae (29), Streptococcus pneumoniae (2), as Gram-positive cocci, and Haemophilus influenzae (1), Haemophilus parainfluenzae (1), Bordetella pertussis (12), Salmonella sp. (4) and Campylobacter jejuni (103) as Gram-negative bacilli. Against stock strains of bacteria, MICs of 10 drugs (RKM, erythromycin (EM), josamycin (JM), midecamycin (MDM), midecamycin acetate (MOM), clindamycin (CLDM), amoxicillin (AMPC), cefaclor (CCL), minocycline, ofloxacin (OFLX] were determined. Against isolates from patients who underwent treatment with RKM, MICs of only 4 drugs (RKM, EM, JM, MOM) were determined. Measurements were made on plasma and urinary concentrations of RKM and its urinary recovery rates after patients including 6 boys with ages between 5 years 1 month and 11 years 6 months were administered with RKM (dry syrup). Two groups of 6 boys were administered between meals with RKM at dose levels of 5 and 10 mg/kg, respectively. Clinical and bacteriological effects of RKM were evaluated for 175 patients including 5 cases of pharyngitis, 3 tonsillitis, 32 pneumonia, 17 mycoplasmal pneumonia, 34 atypical pneumonia, 28 streptococcal infections, 29 Campylobacter enteritis, 4 Salmonella gastroenteritis, and 23 enteritis due to unknown organisms. Five drop-out cases were excluded from the evaluations. In the evaluable cases, an average dose level used was 31.8 mg/kg/day, with a daily dose divided into 3 to 4 administrations and with an average treatment duration of 9 days. Adverse reactions of RKM and its effects on laboratory test values were investigated in these patients including the drop out cases. Obtained results of these studies are summarized below. 1. The GA-test produced pH values indicating that amounts of gastric acid were mostly either normal or high in 42 of the 43 subjects tested (97.7%), and only one low acid case (2.3%) was observed.(ABSTRACT TRUNCATED AT 400 WORDS)

We studied the lymphocytes and serum suppressive factor in patients with Mycoplasma pneumoniae pneumonia. Skin testing for delayed hypersensitivity to tuberculin was performed in 44 patients with pneumonia associated with M. pneumoniae infection. These patients were tuberculin-positive. Twenty-five patients showed a transient negative tuberculin reaction in the acute stage and 19 had a positive reaction. In tuberculin-negative patients, peripheral blood T lymphocytes were not significantly reduced; however, the blastogenic lymphocyte response to purified protein derivative (PPD) and PPD-induced gamma-interferon production were significantly reduced when compared with those in tuberculin-positive patients and healthy tuberculin-positive controls. The lymphocyte response of healthy tuberculin-positive controls was not suppressed by adding the serum of the tuberculin-negative patients. These results suggest that tuberculin anergy in patients with M. pneumoniae pneumonia early after clinical onset is due to depressed lymphocyte functions and not to serum factors.

It is not rare that extrapulmonary complications and not pneumonia dominate the clinical picture in infections with Mycoplasma pneumoniae, as is illustrated by three cases. In the first, a young woman developed an acute, but ultimately completely reversible, polyradiculitis after a Mycoplasma pneumonia. The second patient sustained a thoracic transverse myelitis which regressed rapidly and completely under treatment with erythromycin and prednisone. In the third one, the Mycoplasma pneumonia was complicated by a generalized hypersensitivity vasculitis affecting many organs. A largely reversible renal vasculitis was demonstrated angiographically.
