We have evaluated S-1108 fine granules for therapeutic effectiveness in children. The results are summarized as follows. 1. A clinical study was performed with 16 children with infections, including 8 with acute tonsillitis, 3 with acute pharyngitis, 2 with scarlet fever, 1 each with acute bronchitis, pertussis and urinary tract infection. Doses ranging from 8.8 to 10.6 mg/kg body weights were given in 3 divided portions. Durations of treatment ranged from 2 to 15 days. The therapeutic responses were considered "excellent" in 1 and "good" in 13, with an efficacy rate of 87.5%, and the bacteriological eradication rate was 91%. 2. No adverse reactions were observed. In laboratory tests, eosinophilia was observed in one patient. It was concluded the S-1108 was promising drug for the treatment of bacterial infections in children.

Pharmacokinetic and clinical studies on S-1108, a new oral cephem antibiotic, were performed in pediatric infections and the following results were obtained. 1. Pharmacokinetics studies Pharmacokinetics of S-1108 was studied in 4 children (3 y 7 m-11 y 1 m) using doses of 2 mg/kg (n = 2) and 4 mg/kg (n = 2). The average peak plasma level was 0.88 microgram/ml at 2 hours after administration of 2 mg/kg and 2.00 micrograms/ml at 3 hours after administration of 4 mg/kg, and plasma half-lives were 1.45 and 0.96 hours, respectively. Average cumulative urinary recovery rates at 0-6 hours were 30.0 and 34.8%, respectively. 2. Clinical studies S-1108 was administered to 32 patients with various infectious diseases (6 with acute tonsillitis, 2 each with pertussis and acute bronchitis, 3 with pneumonia, 4 with scarlet fever, 5 with impetigo contagiosa, 6 with acute urinary infection and 1 each with subcutaneous abscess, impetigo, vulvitis and urethritis) at daily doses between 6-12 mg/kg/day, t.i.d., for 5-12 days. Clinical responses were excellent in 17 patients, good in 13, and poor in 2, and the efficacy rate was 93.8%. Bacteria were identified and 33 strains of 12 species were found. The eradication rate was 93.9%. No side effects were observed in 43 patients. Abnormal laboratory test values were observed in 2 patients, 1 with elevation of eosin. and the other with elevations of GOT and GPT. The results suggest that S-1108 may be a very useful and safe drug for the treatment of pediatric infections.

Bacteriological, pharmacokinetic and clinical studies on cefditoren pivoxil (CDTR-PI, ME 1207) in granules, a new oral cephalosporin, were performed in the field of pediatrics. The results are summarized below. 1. Antibacterial activities: Antibacterial activities of CDTR were studied against Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae, Haemophilus parainfluenzae and Branhamella catarrhalis in comparison with those of cefteram (CFTM), cefixime (CFIX), cefaclor (CCL), cefpodoxime (CPDX) and cefotiam (CTM). MIC80's of CDTR against S. aureus, S. pneumoniae, S. pyogenes, H. influenzae, H. parainfluenzae and B. catarrhalis were 1.56, 0.39, < or = 0.025, < or = 0.025, 0.05 and 0.20 micrograms/ml, respectively. These results showed that CDTR has high antibacterial activities against these organisms. 2. Absorption and excretion: Serum concentrations and urinary recovery rates of CDTR-PI (administered in granules) were determined. Upon single oral doses of 3 mg/kg and 6 mg/kg, the peak serum concentrations were 0.5-2.45 micrograms/ml at 2 to 4 hours and 1.79-4.05 micrograms/ml at 1 to 4 hours, respectively, and T 1/2 was 1.07-9.67 hours and 0.99-3.00 hours, respectively. At 8 hours after dosing, serum concentrations were 0-0.87 micrograms/ml with a dose of 3 mg/kg and 0.27-0.73 micrograms/ml with 6 mg/kg. These values indicated that the drug has a dose-dependent pharmacokinetic behavior. Urinary recovery rates in the first 8 hours were 12.9-34.2% with a dose of 3 mg/kg and 11.8-26.9% with 6 mg/kg. 3. Clinical study: Clinical efficacies were examined in a total of 81 cases consisting of 20 cases of acute bronchitis, 13 of acute pneumonia, 21 of tonsillitis, 5 of pharyngitis, 7 of scarlet fever, 2 each of impetigo, otitis media and purulent cervical lymphadenitis, 1 of pertussis and 8 of UTI. The clinical efficacy rate was 97.5% (79/81), and bacteriological eradication rate was 100% (76/76). As for side effects, 2 cases of watery stools and 1 case of minor elevation of GPT were observed.

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.

This article reviews the existing literature about acute bronchitis, a condition commonly diagnosed but poorly defined. The little epidemiologic research that has been done has failed to identify a microbiologic etiology approximately 60% to 85% of the time. The majority of cases appear to be caused by viruses, but 25% of adults with nonspecific lower respiratory symptoms may actually have pertussis. Mycoplasma pneumoniae and Chlamydia pneumoniae probably play minor roles. Although clinicians frequently prescribe antibiotics to patients they have diagnosed with acute bronchitis, there is little evidence in support. General treatment studies have failed to demonstrate benefit, and the natural history of even potentially curable pathogens is not altered by antimicrobial therapy. Some recent studies suggest that albuterol may be the best treatment choice for acute bronchitis; it can successfully ameliorate symptoms, and does not pose the same public health risk as inappropriate antibiotics do. Erythromycin may occasionally be indicated for patients in frequent contact with small infants not yet immunized against pertussis, but careful surveillance of the child is probably more effective than treating the contagious adult.

Asthma and allergic disorders have been on the increase in recent decades, especially among children living in affluent countries; some aspects of the "Western" way of life may explain this trend. We evaluated the relation of aeroallergen skin test reactivity with socioeconomic status, number of siblings, and respiratory infections in early life. We examined a total of 2,226 schoolchildren, ages 7-11 years, in three areas of Lazio, Italy. Skin prick tests were performed to assess atopic status, and self-administered questionnaires were completed by the parents. The prevalence of prick test positivity was greater among children whose fathers were in the highest educational level than among those in the lowest [prevalence ratio (PR) = 1.58; 95% confidence interval (CI) = 1.21-2.06]. There was also a lower prevalence of atopy among larger sibships (PR = 0.38 for subjects with four or more siblings vs those without siblings; 95% CI = 0.14-0.99). A history of bronchitis or bronchiolitis before age 2 years was weakly associated with an increased risk of atopy, whereas a history of pertussis or pneumonia was not. Both the effect of father's education and the influence of larger sibship size remained when we adjusted for several potential confounding factors, including respiratory infections in early life. We infer that higher socioeconomic status and lower sibling number are determinants of atopy in this Italian population. Protection arising from early severe respiratory infections does not explain this association, although we cannot exclude a role for other viral infections.

This paper has analyzed respiratory syncytial virus lower respiratory tract infections in 201 hospitalized children. In children with wheezing, erythrocyte sedimentation rate (ESR) was significantly higher in those with pneumonia than with syndroma pertussis, while the white blood cell (WBC) count was significantly lower in patients with bronchitis than in those with bronchiolitis and syndroma pertussis. Bronchodilatators were applied in 75.6% and corticosteroids in 20% of patients. Ten patients were ventilated. Fatal disease outcome was observed in one infant. Twelve consecutive-year study of respiratory syncytial virus (RSV) infections showed that 27.3% of these diseases were bronchiolitis and pneumonia.

Acute bronchitis is an acute cough illness in otherwise healthy adults that usually lasts 1 to 3 weeks. This review describes the pathophysiology of the condition and provides a practical approach to the evaluation and treatment of adults with uncomplicated acute bronchitis. Practical points to be made are:1. Respiratory viruses appear to cause the large majority of cases of uncomplicated acute bronchitis.2. Pertussis infection is present in up to 10% to 20% of adults with cough illness of more than 2 to 3 weeks' duration. No clinical features distinguish pertussis from nonpertussis infection in adults who were immunized against pertussis as children.3. Transient bronchial hyperresponsiveness appears to be the predominant mechanism of the bothersome cough of acute bronchitis.4. Ruling out pneumonia is the primary objective in evaluating adults with acute cough illness in whom comorbid conditions and occult asthma are absent or unlikely. In the absence of abnormalities in vital signs (heart rate > 100 beats/min, respiratory rate > 24 breaths/min, and oral body temperature > 38 degrees C), the likelihood of pneumonia is very low.5. Randomized, placebo-controlled trials do not support routine antibiotic treatment of uncomplicated acute bronchitis.6. Randomized, placebo-controlled trials have shown that inhaled albuterol decreases the duration of cough in adults with uncomplicated acute bronchitis.7. Intervention studies suggest that antibiotic treatment of acute bronchitis can be reduced by using a combination of patient and physician education. Decreased rates of antibiotic treatment are not associated with increased utilization, return visits, or dissatisfaction with care.

The following principles of appropriate antibiotic use for adults with acute bronchitis apply to immunocompetent adults without complicating comorbid conditions, such as chronic lung or heart disease.1. The evaluation of adults with an acute cough illness or a presumptive diagnosis of uncomplicated acute bronchitis should focus on ruling out serious illness, particularly pneumonia. In healthy, nonelderly adults, pneumonia is uncommon in the absence of vital sign abnormalities or asymmetrical lung sounds, and chest radiography is usually not indicated. In patients with cough lasting 3 weeks or longer, chest radiography may be warranted in the absence of other known causes.2. Routine antibiotic treatment of uncomplicated acute bronchitis is not recommended, regardless of duration of cough. If pertussis infection is suspected (an unusual circumstance), a diagnostic test should be performed and antimicrobial therapy initiated.3. Patient satisfaction with care for acute bronchitis depends most on physician-patient communication rather than on antibiotic treatment.
