In the determination of the etiology of acute bronchitis in children, a complex of microbiological and immunological methods should be used. The isolation of Streptococcus pneumoniae and Haemophilus influenzae at a concentration of greater than or equal to 10(4) cels/ml from tracheobronchial washings is the early and most significant method for the determination of the etiology and therapy of acute bronchitis. On the basis of microbiological and immunobiological criteria, the etiological role of S. pneumoniae has been determined in 78% of patients and that of H. influenzae, in 48% of patients, mainly in association with pneumococci.

Branhamella catarrhalis, a normal commensal of the oropharynx, is increasingly recognized as an important cause of bronchitis and bacterial pneumonia. Six patients with B. catarrhalis pneumonia documented by transtracheal aspirate or blood culture were studied, and 429 previously reported cases of B. catarrhalis bronchitis and pneumonia were reviewed. The mean age of patients with B. catarrhalis infection was 64.8 years, and preexisting chronic obstructive pulmonary disease was common. The typical clinical picture was that of purulent tracheobronchitis; patients with pneumonia were not severely ill and differed from those with bronchitis mainly by the presence of patchy lower-lobe infiltrates on chest roentgenogram. Fifty-three percent of reported strains produced beta-lactamase. Thirty-nine percent of the cultures were mixed, predominantly with Haemophilus influenzae and Streptococcus pneumoniae. The microbiologic, immunologic, and clinical features of B. catarrhalis infection, as well as the antimicrobial susceptibilities of this organism, were reviewed. The reasons for the lack of recognition of this common pathogen and possible solutions were considered.

Although the role of antimicrobial therapy in the treatment of chronic bronchitis is unproven, physicians continue to look for microbial etiologies to explain episodes of clinical acute bronchitis and better antimicrobial agents with which to treat these episodes. The newest major pathogen of acute bronchitis is Branhamella catarrhalis, a neisseriae-like organism that has become the third most commonly recognized cause of this disease after Haemophilus influenzae and Streptococcus pneumoniae. Because it produces beta-lactamase, B catarrhalis presents a special problem in drug therapy. A number of newer antimicrobials have been introduced which offer potential in the therapy of acute bronchitis, including the enteric coated erythromycins, several new oral cephalosporins, and a large new class of drugs called the fluorinated quinolones. This report addresses the current level of knowledge on these newer agents and therapies of acute bronchitis.

Laboratory and clinical studies on rokitamycin (RKM) dry syrup, a new macrolide antibiotic, were carried out in the field of pediatrics. The results are summarized as follows. 1. Plasma concentrations and urinary recovery rates after oral administration on fasting of RKM dry syrup at doses of 10 mg/kg and 20 mg/kg to 2 and 1 cases, respectively, were determined. Peak plasma levels were obtained in 30 minutes after administration of both dosages with half-lives of 1.5 to 2.2 hours. A clear-cut dose response was observed. Urinary recovery rates in the first 6 hours after administration ranged from 1.75 to 2.26%. 2. The MICs of RKM against 80 clinical isolates (Streptococcus pyogenes 9, Streptococcus pneumoniae 14, Branhamella catarrhalis 4, Haemophilus influenzae 27, Haemophilus parainfluenzae 9, Haemophilus haemolyticus 2, Haemophilus parahaemolyticus 14 and Campylobacter jejuni 1) were compared with MICs of midecamycin acetate (MOM), josamycin (JM) and erythromycin (EM). The antibacterial activity of RKM was superior to those of MOM and JM and slightly inferior to that of EM. 3. Twenty-eight pediatric patients with acute infectious diseases (acute tonsillitis 4, streptococcal infection 4, acute bronchitis 9, pneumonia 4, mycoplasmal pneumonia 2 and Campylobacter enteritis 5) were treated with RKM dry syrup at a daily dose of 12-42.9 mg/kg t.i.d. as a rule. Efficacy rates were 92.9% clinically and 58.6% bacteriologically. 4. No adverse reactions were observed. Abnormal laboratory findings were mild; thrombocytosis in 2 and eosinophilia in 1. 5. The taste and the odor of RKM dry syrup preparation were sufficiently tolerable for the pediatric patients to accept it.

The usefulness of a new macrolide antibiotic rokitamycin (RKM, TMS-19-Q) was evaluated in the field of pediatrics. 1. Twenty seven patients were enrolled in the study. One patient was excluded from the study because the illness was due to a viral infection. They included 14 boys and 13 girls with ages 7 months to 9 years 11 months. 2. The patients were treated with RKM at daily doses ranging 19.2-41.1 mg/kg, divided into 3 equal portions. The administration was done orally at fasting, lasting 2-15 days, with total doses of 22.2-500.0 mg/kg. 3. The patients were diagnostically classified into the following categories: 9 with acute pharyngitis, 15 with acute bronchitis, and one each with pneumonia, purulent lymphadenitis and Campylobacter enteritis. 4. The clinical response to the treatment was good or excellent in 22 of the patients with an overall efficacy rate of 81.5%. An efficacy rate of 88.9% was achieved for the patients with acute pharyngitis, 80.0% for those with acute bronchitis, and 100% for the patient with purulent lymphadenitis and the patient with Campylobacter enteritis. From the patient with pneumonia whose response was evaluated "fair" was Haemophilus influenzae isolated by culturing pharyngeal material. This organism was found resistant to RKM by the disk method. 5. Bacteriological responses were as follows; of 26 isolates presumed to be pathogens, 9 were eradicated, 5 decreased, 7 unchanged and 5 unknown, with an eradication rate of 42.9%. 6. Neither adverse reactions nor abnormal changes in laboratory findings were observed with the medication in any patients during and after the end of the treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

A total of 29 patients with pediatric infections was treated orally with 21.4-44.4 mg/kg/day of rokitamycin (RKM) dry syrup. The obtained results are summarized as follows. 1. Clinical responses to RKM in 24 evaluable patients were excellent in 2 and good in 3 of 5 patients with tonsillitis and laryngitis; excellent in 3 and good in 5 of 8 patients with bronchitis; excellent in 3, good in 2 and fair in one of 6 patients with bronchopneumonia; excellent in 2 and good in the other of 3 patients with psittacosis; and excellent in 2 of 2 patients with Campylobacter colitis. The overall efficacy rate was 95.8%. 2. Bacteriological responses to the drug were: reduction in 1 and no change in the other of 2 strains of Streptococcus pyogenes; eradication of a strain of Streptococcus pneumoniae and 2 strains of Staphylococcus aureus; eradication of 2 and no change in 3 of 5 strains of Haemophilus influenzae; and eradication of 2 out of 2 strains of Campylobacter spp. 3. Diarrhea was complained of as an adverse reaction to the RKM medication by 1 patient, abdominal pain was reported by another, and anorexia by another of the 27 patients treated. Laboratory examination was performed on some patients, but not abnormal test values were found except in 1 case showing an increase in platelet count from 27.6 to 78.2 X 10(4)/mm8. The results suggested that RKM dry syrup might be a very useful and safe drug for the treatment of pediatric infections.

Pharmacokinetic, bacteriological and clinical studies on sultamicillin (SBTPC) fine granule were carried out in the field of pediatrics. The results obtained are summarized as follows. 1. Antibacterial activities of SBTPC against clinically isolated strains of Haemophilus influenzae, Haemophilus parainfluenzae, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Staphylococcus aureus, Branhamella catarrhalis, and Escherichia coli were compared with those of ampicillin (ABPC). SBTPC was superior to ABPC especially against beta-lactamase producing H. influenzae, E. coli, S. aureus, and B. catarrhalis. 2. Serum concentrations and urinary excretion rates of sulbactam (SBT) and ABPC after administration of SBTPC fine granule at a dose level of 10 mg/kg in 2 cases were determined. Mean half-lives of SBT and ABPC in the serum following oral administration were about 1.33 and 1.61 hours respectively. Mean urinary recovery rates of SBT and ABPC in 6 hours after oral administration at a dose of 10 mg/kg were 58.7% and 49.6% respectively. 3. SBTPC fine granule was administered to 20 pediatric patients with various bacterial infections (pneumonia 8 cases, bronchitis 2, pharyngitis 2, tonsillitis 4, subcutaneous abscess 1 and urinary tract infection 3). The overall clinical efficacy rate was 100% and the overall bacteriological eradication rate was 75%. 4. No adverse reactions were observed except 1 case of loose stool. No abnormal laboratory test values were observed. These results indicate the usefulness of SBTPC fine granule in the treatment of bacterial infections in children.

Sultamicillin fine granules were used orally in 18 pediatric patients with infections in doses ranging 7.3-10.0 mg/kg t.i.d. or q.i.d. The following is a summary of the results: 1. Clinical efficacies in 16 cases with tonsillitis were excellent in 13 cases, good in 2 cases and fair in 1 case. Efficacy in 1 case of bronchitis and 1 case of pneumonia were good. The overall efficacy rate in the 18 cases was 94.4%. 2. Four out of 5 strains of Staphylococcus aureus were eradicated but 1 strain persisted. Three out of 7 strains of Haemophilus influenzae were rated as eradicated, 1 strain as decreased and 3 strains as persisted. Two strains of Streptococcus pyogenes and 3 strains of Haemophilus parainfluenzae were eradicated. The bacteriological efficacy rate for the 17 strains was 70.6%. Four strains out of the 17 were found to produce beta-lactamase and 3 strains were suspected, to produce the enzyme, but of these 7 strains, 5 strains were eradicated. 3. Diarrhea and loose stool were observed as side effects in each of 2 cases. It appeared that diarrhea was related to this drug. A slight elevation of GOT was observed in 1 case in laboratory tests. 4. This drug appears to be easy for children to take in terms of taste and smell.

Roxithromycin is a new macrolide antibiotic with good absorption and a longer half-life than erythromycin. Worldwide clinical studies to evaluate its efficacy and safety in the treatment of infections of the lower respiratory tract have achieved a clinical success rate of 89% with few and mild side effects. Double-blind studies comparing roxithromycin with cephradine, erythromycin ethylsuccinate and doxycycline in pneumonia, acute exacerbations of bronchitis in patients with chronic obstructive airways disease, and acute bronchitis have been done. The clinical response to comparative regimens has been similar and ranges from 60% response with either regimen in patients with chronic airways disease to 90% response in patients with acute bronchitis or pneumonia. Roxithromycin appears to be as effective as erythromycin or doxycycline for the treatment of either Streptococcus pneumoniae or Haemophilus influenzae infections. A large double-blind trial comparing cephradine and roxithromycin in 90 cases of bacteriologically confirmed pneumococcal pneumonia in South African gold miners resulted in a 93% and 100% respective clinical response rate. The bacteriological results revealed interesting results in this same study, in that cultures from 17% of patients receiving roxithromycin and 23% of those receiving cephradine remained positive for S. pneumoniae after therapy was finished and an excellent clinical response had been obtained. Side effects in all studies have been transient and mild, with an elevated transaminase value being the most common in both roxithromycin and erythromycin or cephradine regimens. Roxithromycin appears to be a safe and effective oral antibiotic for the treatment of pneumococcal pneumonia and other infections of the lower respiratory tract, and is as effective as erythromycin, doxycycline or cephradine.

Flomoxef (FMOX, 6315-S), a new antibacterial drug, was administered to 9 cases with respiratory tract infections for a duration of 8 approximately 16 days at a daily dose of 2 g. Diagnosis of these patients were bronchopneumonia 5 cases, chronic bronchitis 3 cases and acute bronchitis 1 case. From transtracheal aspiration several organisms were isolated; Haemophilus influenzae was isolated in 3 cases, Streptococcus pneumoniae in 3 cases, H. influenzae plus Branhamella catarrhalis in 1 case, Streptococcus dysgalactiae plus Neisseria meningitidis in 1 case and Corynebacterium pseudodiphtheriticum in 1 case. The clinical efficacy was good in all 9 cases, the efficacy rate was 100%. All the bacteria were eliminated. Side effects were not observed. From these results, it appears that FMOX is a valuable drug in the treatment of respiratory tract infections.
