Clarithromycin (TE-031, A-56268), a new macrolide antibiotic, was administered to a total of 25 child patients (age range: 4 months-12 years) to treat infections; the patients consisted of 23 children who received the drug in the form of granules for children and 2 patients who were given tablets. Daily dosages were 14.3 mg/kg (in 2 divided doses) in 1 patient, and 18.3-30.3 mg/kg (in 3 divided doses) in the other 24 patients. Lengths of administration ranged from 4 to 13 days with 6-8 days for 18 of the patients. The results obtained are summarized as follows. 1. Clinical efficacy evaluations for various infections were as follows: 1 excellent, 4 good and 2 fair cases in 7 cases of pertussis; 3 excellent, 2 good and 1 fair cases in 6 cases of tonsillitis; 1 good case in tonsillitis with bronchitis; 1 excellent and 3 good cases in 4 cases of bronchitis; 1 excellent and 1 good cases in 2 cases of pneumonia; and 4 excellent and 1 good cases in 5 cases of enteritis. Thus, evaluations of a total of 25 patients showed 10 excellent, 12 good and 3 fair cases, with no poor cases. The overall clinical efficacy rate was, therefore, 88.0%. These results were attributed to good antimicrobial activity and absorption of TE-031. 2. Causative bacteria were isolated from 12 of the patients. Bacteriological efficacies of TE-031 on those strains were investigated with the following results. Of 5 Haemophilus influenzae strains, 3 were eliminated, 1 was reduced, and no change was observed in the other.(ABSTRACT TRUNCATED AT 250 WORDS)

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)

Epidemic patterns of 12 infectious diseases based on the data derived from the surveillance system of infectious diseases in Japan are analyzed. Weekly numbers of patients per one monitor station (general clinics and hospitals) are calculated by prefecture. Based on these data, the patterns of epidemic are classified into five categories: Category 1, nationwide outbreak of short duration (rotavirus enteritis, hand-foot-mouth disease and herpangina); Category 2, nationwide outbreak of long duration (varicella); Category 3, concurrent outbreaks in several districts (rubella and erythema infectiosum); Category 4, epidemic of long duration in several prefectures at different times (measles, mumps, pertussis, streptococcal infection and atypical pneumonia); Category 5, unclear epidemic pattern (exanthema subitum).

Neutrophil infiltration is a prominent feature of Clostridium difficile-associated enteritis and colitis. The aim of this study was to examine the importance of neutrophil recruitment and neutrophil-mediated tissue damage in C. difficile toxin A-induced enteritis. Competitive binding experiments using purified 3H-toxin A demonstrated the presence of a single class of medium affinity receptors on rabbit neutrophils (Kd 7 x 10(-8) M). Pertussis toxin and the nonhydrolyzable GTP analog GTPgamma S both inhibited 3H-toxin A binding (by 56 and 65%, respectively), indicating that the rabbit neutrophil toxin A receptor is G protein linked. Toxin A elicited a dose-dependent (25-200 micrograms/ml) stimulation of neutrophil migration in vitro, and this functional effect was also pertussis toxin sensitive (69% inhibition). Treatment of neutrophils with R15.7, a blocking monoclonal antibody to the leuocyte adhesion molecule CD18, inhibited toxin A-stimulated neutrophil migration by 85% in vitro. Pretreatment of rabbits with R15.7 also prevented neutrophil infiltration of toxin A-exposed ileal loops in vivo as determined by histologic examination and by ileal tissue myeloperoxidase levels. Furthermore, R15.7 effected a substantial inhibition of fluid secretion (by 65%), mannitol permeability (by 66%), and histologic damage in toxin A-exposed ileal loops. Anti-CD18 (R15.7) had no inhibitory effect on cholera toxin enterotoxicity. These data demonstrate that C. difficile toxin A is a proinflammatory toxin whose enterotoxic effects are substantially dependent upon neutrophil recruitment.

Fine granules or capsules of azithromycin (AZM) were given to 32 pediatric patients for the treatment of the following diseases: pharyngitis in three cases; tonsillitis in one; bronchitis in six; pneumonia in six; mycoplasmal pneumonia in 14; pertussis and enteritis in one, each. Effectiveness of AZM was evaluated in 30 cases and the drug was rated "excellent" in 18 patients, "good" in 11 and "fair" in one, resulting in a total efficacy rate of 96.7%. Three strains of bacteria were isolated from 3 patients as the causative organisms including: Streptococcus pneumoniae, Haemophilus influenzae and Haemophilus parainfluenzae, from three different patients, respectively. One patient complained of mild diarrhea, another patient mild urticaria. Abnormal laboratory test results were reported as follows: one patient showed a slight decrease in leukocyte count, three patients showed slight increases in eosinophils, and one patient had slight elevations in GOT and GPT. The above results suggest that AZM is a useful antibiotic drug in the treatment of pediatric patients with various bacterial infections.

Erythromycin, the prototypical macrolide, has been widely used since the 1950s in the management of pediatric infections. Erythromycin is the drug of choice for infants and children with Legionnaire's disease, pertussis, diphtheria, lower respiratory tract infections caused by Mycoplasma pneumoniae, Chlamydia pneumoniae and Chlamydia trachomatis and enteritis caused by Campylobacter jejuni. It is also indicated for treatment of syphilis; for streptococcal, staphylococcal and pneumococcal infections; genital infections caused by Ureaplasma urealyticum; and for the prevention of rheumatic fever and endocarditis in patients who are allergic to beta-lactam antibiotics. The new macrolides azithromycin and clarithromycin are also active against Borrelia burgdorferi, Helicobacter pylori, Mycobacterium avium-intracellulare complex, Cryptosporidium spp. and Toxoplasma gondii. Erythromycin is associated with a low risk of serious side effects, although gastric distress occurs in a significant proportion of patients. Drug interactions with theophylline, carbamazepine, warfarin, cyclosporine, terfenadine and digoxin limit erythromycin use. The newer macrolides azithromycin and clarithromycin are more stable, better absorbed and better tolerated than erythromycin. Azithromycin is more active than erythromycin against Haemophilus influenzae. Excellent tissue and intracellular penetration may contribute to their clinical efficacy. In children both azithromycin and clarithromycin are indicated for acute otitis media caused by Streptococcus pneumoniae, H. influenzae and Moraxella catarrhalis and for pharyngitis/tonsillitis caused by Streptococcus pyogenes. (As of December, 1996, azithromycin for oral suspension was approved for community-acquired pneumonia in children caused by C. pneumoniae, H. influenzae, M. pneumoniae and S. pneumoniae.) Claritromycin is also indicated for acute maxillary sinusitis, uncomplicated skin and skin structure infections, pneumonia and disseminated mycobacterial infections. Azithromycin and clarithromycin are associated with a lower incidence of gastrointestinal side effects, a low rate of drug discontinuation caused by side effects and a low potential for interaction with other drugs.
