Inhaled silicate dusts may cause lung disease through their surface coordination of iron with subsequent oxidant generation via the Fenton reaction. Pneumoconiosis, irritant bronchitis, focal emphysema, and carcinoma may be produced by oxidants either directly through lipid peroxidation and protein inactivation, or indirectly by oxidant-mediated release of cytokines such as platelet-derived growth factor. The increased incidence of tuberculosis observed among silicate workers could be explained by accumulation of iron complexed by dust particles in the lung and made available to dormant mycobacteria as a virulence factor.

Expectoration of bronchial casts (plastic bronchitis) is an uncommon but ancient problem. Herein we describe a 40-year-old man, with no prior lung disease, who had dyspnea, cough, and expectoration of long branching bronchial casts. No specific cause was delineated, although special stains for eosinophilic granule major basic protein demonstrated occasional foci of eosinophils and small amounts of extracellular major basic protein in the bronchial casts. Various diseases, such as allergic bronchopulmonary aspergillosis, bronchiectasis, and cystic fibrosis, have been associated with the formation of bronchial casts and should be considered in the differential diagnosis. Although most previously reported cases have been associated with some type of pulmonary disease, our patient had no evidence of an underlying pulmonary disorder.

Fibrinolytic system, immune reactivity and isoelectric focusing of serum albumin were examined in 94 patients exhibiting combination of obstructive lung disease (chronic obstructive bronchitis and bronchial asthma) with atherosclerosis. Plasminogen activator showed discrete activity, the discreteness being less in respiratory distress of the I degree but higher in the distress of the II and III degree. Relative number of E-RFC and monocytes expressing receptors to IgM and IgG Fc-fragment decreased. Percentage of EAC-RFC rose. Serum albumin fractions changed pH range due to modification of albumin molecules resultant from forming complexes with fibrinogen degradation products. Concentration of the latter under conditions of respiratory distress induced by obstructive lung diseases associated with atherosclerosis substantially exceeded the standard levels.

Branhamella catarrhalis, formerly Neisseria catarrhalis, is a common bacteriological finding in the upper respiratory tract in infancy, and it ranks third on the list of bacterial causes of otitis media and sinusitis. In adults Branhamella catarrhalis may cause acute exacerbations of bronchitis and pneumonia, especially in patients with chronic lung disease. Branhamella catarrhalis is being recognized more frequently as a nosocomial pathogen and it may cause septicaemia in immunocompromised patients. Resistance to penicillin is prevalent and is due to production of beta-lactamases. The pathogenic potential of this agent should not be overlooked.

Subjects prone to recurrent acute bronchitis were admitted to a six-month double-blind clinical study, in which the value of oral immunization with a preparation of killed Haemophilus influenzae was tested. Most subjects had early smoking-related chronic lung disease, unrecognized by either the patient or his/her doctor. Subjects taking the active agent had a 41% reduction in the total number of episodes of acute bronchitis (P = 0.16), a 60% reduction in the number of episodes of acute wheezy bronchitis (P = 0.02) and a 58% reduction in antibiotic use (P = 0.07). The power of analysis was restricted by the small study group. Parameters of episode severity favoured the test group, suggesting that individual episodes of acute bronchitis in subjects taking an oral preparation of killed H. influenzae were less severe than in those taking placebo tablets. Oral immunization with H. influenzae selectively reduced the increase in colonization of the oropharynx with H. influenzae which occurred in the group taking placebo. This is the first demonstration that the common mucosal system can be activated to modify a colonization pattern at a distant site.

There is no general agreement on the concepts of chronic obstructive pulmonary disease (COPD) yet in Japan, although there have been significant advances in the understanding of its concepts in the United States and Europe. The purpose of this presentation as the opening remark to this panel discussion is to review the concepts and history of chronic obstructive pulmonary disease (Tables 1, 2), and also to summarize the general concepts concerning COPD in Japan at present. More than 30 years ago, a Ciba Guest symposium first proposed the main subdivisions of chronic non-specific lung disease (CNSLD), consisting of chronic bronchitis and generalized obstructive lung disease (GOLD). Many papers addressed this theme focusing on the definition and concepts of COPD for a long period after the Ciba Guest Symposium. The ATS and ACCP joint committee on pulmonary nomenclature (1975) reported that the term of COPD refers to diseases of uncertain etiology characterized by persistent slowing of airflow during forced expiration, and the committee recommended that chronic obstructive bronchitis or chronic obstructive emphysema be used, whenever possible. However, in many patients it is still difficult determine what extent the airway obstruction result from emphysema and to what extent it results from an accompanying chronic obstructive bronchitis, as Burrows described. Fishman (1980) and Burrows (1981) suggested that if the patient is thought to have a combination of chronic obstructive bronchitis and pulmonary emphysema, the case should be so diagnosed.(ABSTRACT TRUNCATED AT 250 WORDS)

Cluster analysis was used to examine the nature and magnitude of changes in left ventricular pump function in relation to the severity of primary bronchial obstruction in patients with non-atopic bronchial asthma (n = 45) and chronic obstructive bronchitis (n = 45). In the patients with obstructive lung disease, central hemodynamic changes were found to be determined by the bronchial patency and independent of the pathogenesis of the obstruction. During a remission there was a significant reduction in total peripheral resistance as compared to the values seen in healthy subjects, whereas in moderate or severe obstruction there was a marked increase in total peripheral resistance and a decrease in stroke volume and cardiac output. A drastic bronchial obstruction was followed not only by central hemodynamic changes, but a fall in ejection fraction and a rise in left ventricular end-systolic and end-diastolic volumes.

Advanced emphysema with bronchitis is associated with significant weight loss and malnutrition, the true cause of which has not been clearly identified. The purpose of this exploratory study was to compare plasma amino acids and related compounds and catecholamines in a group of patients with advanced end-stage emphysema with a control group of similar age and sex in an effort to further understand this malnourished state. Fasting blood samples were obtained by venipuncture after a rest period. Plasma amino acid levels were determined by ion exchange high pressure liquid chromatography with fluorometric detection. Plasma catecholamines were determined by radioenzymatic analysis. Anthropometric measurements, the usually accepted biochemical markers of nutrition, dietary analysis, pulmonary function tests, and a historical analysis of the state of health including drug use and smoking history in each subject were analyzed. Ages and heights were comparable, whereas weights were significantly decreased in the patients with emphysema. Total serum protein and serum albumin values were significantly lower in the patient group. Significant respiratory muscle weakness was indicated by reduced negative inspiratory force in these end-stage patients, contrasting with well-preserved muscle strength usually found in obstructive lung disease. The dietary caloric intake of the patients was comparable to that of the control subjects. We conclude that the fine balance of the amino acid pool in patients with bronchitis and emphysema is well preserved, except for significant elevations of aspartic acid, glutamine, and cystine, and a decreased level of leucine. In addition, norepinephrine levels were significantly increased. Weight loss in patients with emphysema and bronchitis is likely due to increased energy demands related to hypermetabolism.

The efficacy of cefonicid and of ceftriaxone, administered once daily for the treatment of lower respiratory tract bacterial infections (pneumonia or bronchitis), was evaluated and compared in 118 patients with chronic lung disease. The patients were randomly assigned to receive 1 gm of either drug, intravenously or intramuscularly, daily for three to 11 days (mean, seven days). Pathogenic bacteria were isolated from sputum in 59% of patients; Haemophilus influenzae and Streptococcus pneumoniae predominated. Clinical cure or improvement was noted in 95% and 93% of patients treated with cefonicid and ceftriaxone, respectively, and bacteriologic cure or improvement in 69% and 81% (the differences were not significant). Side effects were infrequent and similar in the two treatment groups, except that diarrhea was more common in the ceftriaxone group (11%, versus 4.4% in the cefonicid group). It is concluded that patients with chronic lung disease who experience acute exacerbations associated with infection caused by H influenzae or S pneumoniae, or other susceptible organisms, can be effectively treated with once-daily administration of either cefonicid or ceftriaxone.

Ninety-one patients with community-acquired lower respiratory infections were treated orally in a comparative 10-day trial of ofloxacin versus amoxicillin or erythromycin. Approximately one-half of the patients had no major underlying disease and the other half had some form of chronic lung disease. Pneumonia was present in 31 percent of the patients and the remainder had purulent bronchitis. Bacterial pathogens were recovered from 60 percent of the patients, with Haemophilus influenzae (33 isolates) and Streptococcus pneumoniae (16 isolates) being the most common. Ofloxacin was found to be a safe, well-tolerated therapeutic agent, which was as effective clinically as amoxicillin or erythromycin and with an advantage of less frequent administration. Ofloxacin was more effective than amoxicillin (90 percent versus 75 percent; p = 0.05) in elimination of pathogenic bacteria from lower airway cultures. Caution should be exercised in the use of ofloxacin, at least in short-term treatment regimens, with anaerobic pulmonary infections; additional information is needed for S. pneumoniae given the relatively high minimal inhibitory concentrations for this species.
