During 9 months (from January 1988 to September 1988), we experienced 82 patients (94 episodes) of respiratory infections with Branhamella catarrhalis in 5 different hospitals. There were 11 patients of acute bronchitis, 8 patients of pneumonia, 56 patients of chronic bronchitis (68 episodes), 3 patients of bronchiectasis, 3 patients of bronchial asthma with infection and chronic pulmonary emphysema in one patient. Ten cases of acute bronchitis and 3 cases of pneumonia had a recent history of common cold, with no underlying disease. There were 68 episodes of acute exacerbation of chronic bronchitis, the highest among 94 episodes of all respiratory infection. In chronic bronchitis the single pathogen B. catarrhalis was more than B. catarrhalis associated with other pathogens. H. influenza was associated with B. catarrhalis in in most cases of polymicrobial infection. beta-lactamase producing B. catarrhalis was 71% and oral penicillin was not effective in 8 cases of infection by beta-lactamase producing strains. These results show that B. catarrhalis is very important as a common pathogen of respiratory infection.

Sulbactam/cefoperazone (SBT/CPZ), a new antibacterial drug, was administered to 14 cases with respiratory infections for a duration of 5 approximately 13 days at a daily dose of 4 g. Diagnoses of these patients were 7 respiratory tract infections, and 7 bronchopneumonias. The underlying diseases were chronic pulmonary emphysema in 6 cases, bronchial asthma in 2 cases, and one each of bronchiectasis, diffuse panbronchiolitis and lung cancer with bronchoesophageal fistula. All patients had underlying respiratory diseases and/or were more than 70 years old. The rate of clinical efficacy was 78.6%. The incidence of penicillinase production by isolated bacteria was 18.2% and that of cephalosporinase was 63.6%. SBT/CPZ was expected to be more effective than CPZ alone in 3 cases judging from the susceptibility of the bacterial strains concerned, to antibiotics. No side effects were observed. We conclude that SBT/CPZ is useful in the treatment of respiratory infections of patients of advanced age and/or with underlying respiratory diseases.

I found the recent increase during the past eight years of the incidence of respiratory infections caused by Branhamella catarrhalis. Namely, I experienced 74 cases (93 episodes) of the respiratory infections; 5 pneumonia, 14 acute bronchitis, 1 lung abscess, 36 chronic bronchitis, 7 chronic bronchiolitis, 21 bronchiectasis and 9 chronic pulmonary emphysema with infection. In 65 of 93 infectious episodes, Branhamella catarrhalis was isolated as a pure culture and in 28 episodes it was associated with other organisms, 13 Haemophilus influenzae etc. In all the cases, a positive correlation was found between beneficial clinical results and disappearance of the organism from the sputum. Minimum inhibitory concentrations of the representative beta-lactam and other antibiotics against 104 strains were determined. All of these strains were obtained during last four years from 1980 to 1983 from the purulent sputa as the main pathogen. Annually, this organism has significantly acquired resistance to beta-lactams. By 1983, 74% of Branhamella catarrhalis isolated from the purulent sputa became a beta-lactamase producers. And the failure cases of Branhamella catarrhalis infections treated with beta-lactams have increased during the last two years. These results have clearly showed also the importance of Branhamella catarrhalis as the common pathogen for respiratory organ.

Chronic obstructive pulmonary disease (COPD) comprises a spectrum of conditions including chronic bronchitis, emphysema, asthma, and bronchiectasis. It has a prevalence in the United States of 5.1% to 5.4% in the middle-aged to elderly population, with a lower rate in nonsmoking individuals. Moreover, COPD is complicated by frequent and recurring acute exacerbations of chronic bronchitis (AECB). Overall, COPD represents the fourth leading cause of mortality in the United States and is the second leading cause of work disability. This condition is also associated with high morbidity and health care expenditures. Despite the controversy over the need to prescribe antibiotics for patients with AECB, high-risk patients have been identified who will benefit from this therapy.These include, patients with a history of repeated infections (>4 per year), comorbid illnesses (such as diabetes, asthma, coronary heart disease), or marked airway obstruction. Furthermore, a bacterial cause is shown in approximately 50% of AECB episodes, and primarily includes Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae. Additionally, resistance among community-acquired respiratory pathogens in the United States has risen dramatically, with beta-lactamase production evident in 40% of H. influenzae and greater than 95% of M. catarrhalis isolates, and with approximately 10% of pneumococci highly resistant to penicillin and simultaneously resistant to macrolide antibiotics. The criteria used to make choices for antibiotic use in patients with AECB should include knowledge of the frequencies of pathogen resistance and patients' clinical characteristics. An effective antibiotic, however, must be able to rapidly resolve the acute infection with the least patient morbidity and need for hospitalization. Although there remains controversy as to when to initiate antibiotic therapy in patients with AECB, several guidelines have been published.
