207 patients of a geriatric department were immunized against influenza with either tween-ether-split-vaccine or subunit-vaccine in a double blind study. For 6 months the following data were daily registered: rest in bed, fever over 38,5 degrees C, rhinitis, laryngopharingitis, bronchitis, pneumonia, enteritis, medication with antibiotics or chemotherapeutics. In cases with fever over 38,5 degrees C blood tests were taken for serological examination. The immune response against influenza A was excellent in both groups, the titer was higher in the subunit group, only one patient showed influenza infection. The immune response against the type B Hongkong was not satisfactory in both groups. The clinical data showed a significant lower incidence of rhinitis, laryngopharingitis and bronchitis in the group immunized with the tween-ether-split-vaccine. This effect was more distinct within the first 3 months after the immunization than within the second 3 months.

Individuals with chronic lung disease and their families were selected from the Tecumsch community along with similarly selected families as comparison groups and studied for 1-year periods. Occurence of acute respiratory illness was ascertained weekly by telephone and calculated as an annual rate. Persons with chronic bronchitis not only experienced more acute lower respiratory illness than healthy comparison subjects, but total illness rates were somewhat higher as well. Infection rates were determined from blood samples taken 3 times from each participant during the surveillance year. Antibody tests were performed for respiratory syncytial virus, para-influenza virus types 1, 2, and 3, influenza types A and B, coronavirus OC43, Mycoplasma pneumoniae, and Haemophilus influenzae. Differences in serologic infection rates among the subgroups of the population were similar to those seen in the clinical data, with more frequent infection among those with bronchitis than among the comparison subjects. This finding indicates that some degree of increased susceptibility to actual infection existed among those individuals with bronchitis. Influence of smoking on illness and infection rates was also examined. Infections were, in general, more frequent in smokers than in nonsmokers, but illness rates were reversed, suggesting that perception of disease differed in the 2 groups. Rates of illness and infection of other adults in the families of the index individuals with bronchitis were not influenced by the higher rates seen in the index individuals; however, it was of interest that children of persons with bronchitis did have somewhat higher rates of infection than children of comparison subjects.

From October 1976 to June 1977 virological researches have been carried out on 5 subjects with influenza, on 302 children hospitalized in pediatric departments for respiratory illness and 94 children hospitalized in the same departments for other (non respiratory) diseases. The incidence of influenza was moderate and restricted to small epidemic episodes in school and preschool children. The isolated viruses resulted of A type, substantially similar to the prototype strains appeared from 1972 to 1975. Among children hospitalized for respiratory diseases Adenoviruses (6.8%) and, with decreasing frequency, Enteroviruses, paraifluenza viruses and RS have been also isolated. The incidence of isolation of RS virus is significantly related to bronchopneumonia cases in infants under on year of age. The incidence of significant increases of FC antibodies against influenza (A and B) viruses, RS and Myc. pneumoniae in children with bronchitis and broncho-pneumonia is also considerable. The drawing of pharyngeal swabs at different intervals from the entry to the hospital has shown that the shedding of respiratory viruses is generally very short and that hospital cross-infections may occur.

Comprehensive epidemiological studies revealed that every individual is suffering from a respiratory tract infection in the average 6 times a year. 97% of these are caused by viruses. Identical clinical symptoms may be produced by many different agents, thus the etiology of an illness can only be identified by virus isolation and serological tests. The frequency of isolations is varying in adults and in children as well as in ambulatory and in hospitalized patients. The persistently observed susceptibility for new infections is caused by the great variety of possible etiologic agents especially in upper respiratory infections and the peculiarities of local immunity in the respiratory tract. An influence of chilling could not be demonstrated scientifically in spite of controverse clinical observations. It was proved however that allergic individuals succumb more frequently to viral infections. Overweight in infancy increases susceptibility for bronchitis and bronchiolitis. Superinfections by bacteriae are not rarely complications of viral diseases and antibiotic therapy may become necessary eventually. Leucocytosis and an elevated erythrocyte sedimentation rate are only criteria of limited value to distinguish viral and bacterial infections. Specific virostatic therapy is not possible so far for respiratory tract illnesses, but for prophylaxis of infections with influenza A2 amantadine-HCl may be used. Gammaglobulin has a prophylactic effect as well for certain virus infections but is of little use for antiviral therapy.

A human isolate of type A Hong Kong influenza virus (H3N2) was adapted to mice by serial passage. Lung homogenates from mice who received low passage levels contained about the same quantity of virus (10(6.2-6.95) 50% tissue culture infective doses/ml) as those from mice who received high passage levels (10(5.95-6.45) 50% tissue culture infective doses/ml); however, death occurred only in animals given high-passage virus. Passage 3 (P3) and passage 9 (P9) viruses were selected as representative of low-passage and high-passage viruses, respectively. Although minimal differences were detected in infectivity for rhesus monkey kidney tissue cultures and mice, P9 virus was at least 10,000 times more lethal for mice (mean lethal dose = 10(4.2)). Infection with P3 virus was accompanied by minimal bronchitis and bronchiolitis only, whereas P9-infected animals exhibited marked bronchitis, bronchiolitis, and pneumonia. Striking thymic cortical atrophy was also demonstrable in the P9-infected animals and, although virus was more commonly recovered from thymuses from these animals, immunofluorescent studies revealed only a few cells containing influenza virus antigens. To further explore the participation of thymus-derived lymphocytes in influenza, athymic nude mice and furred immunocompetent littermates were given 500 50% mouse infectious doses of P9 virus. Nude mice exhibited an increased survival time and, in contrast to the extensive lung pathology seen in furred littermates, manifested minimal cellular infiltration and no tissue destruction in lungs. Brains from nude mice exhibited encephalomalacia with lymphocytic perivascular cuffing, which was not seen in furred animals. Virus was recovered from brains of 6 of 13 nude mice and 1 of 10 furred animals. The contrasting models suggest that thymus-dependent cells play a significant role in the inflammatory response to influenza virus infection and should prove useful for probing host-virus interactions which characterize influenza virus virulence.

Relative to a particular level of female mortality, male mortality is lower than expected, currently and historically, in Northwestern Europe, Southeastern Europe, and Tropical Latin America; it is higher than expected in Western-Central Europe and in the Far East. The geographical pattern of differentials is attributable primarily to variation in the masculinity of mortality from cardiovascular diseases, neoplasms, and influenza/pneumonia/bronchitis. Over time, male mortality has increased relative to a particular level of female mortality, and these same causes of death are principally responsible. In the 1960's, high masculinity of mortality was associated independently with low proportions in primary activities, high proportions hiring in large cities, and with high discrimination against females in school enrollment combined with poor nutritional standards. The former two variables once again operate primarily through cardiovascular disease, neoplasms, and the respiratory diseases, whereas the discrimination-nutrition interaction appears to operate through infectious diseases. Variations in levels of economic modernization are capable of accounting for a substantial portion of the regional differences, although certain constitutional factors such as physiotype are also plausibly implicated, and they are also congruent with trends in sex mortality differentials.

Proper treatment relieves the symptoms of chronic bronchitis and emphysema to a large extent and helps patients remain active and useful until the last stages of the disease. Not much can be done to halt the natural course, since the disease is well advanced by the time that symptoms appear. Respiratory infections pose a constant threat. They are the primary cause of increased morbidity and mortality in these patients and may well accelerate the disease process. Annual prophylaxis against influenza is recommended, and antibiotic suppression should be considered for patients who have repeated bouts of acute bronchitis. Airways obstruction in emphysema is irreversible, but oral bronchodilators may remedy bronchospasm in chronic bronchitis and in emphysema with a bronchitic component. If sputum is thick and tenacious, postural drainage and chest physiotherapy may be helpful. Corticosteroids should be used only as a last resort. Patients tend to become inactive as the disease progresses. Exercise is important to increase exercise tolerance and overall physical fitness, and the physician should prescribe a specific daily program within the patient's limitations.

An attempt was made to determine the frequency of lung cancer occurrence in different inflammatory processes in the bronchi and pulmonary tissue. 100 cases of lung cancer were studied according to case reports and autopsy finding, the main tumor node and metastases were explored histologically. The data obtained indicated that in 2.2% of cases the development of cancer was preceded by influenza with residual phenomenon such as purulent bronchitis or pneumonia, in 2.3% of cases cancer occurrence was found to be dependent on chronic pneumonia. In 12.1% of cases cancer has arisen in fibrous-focal or cirrhotic tuberculosis with the presence of old caverns; in 14.7% of cases its development was related with pneumosclerosis and bronchiectases, and in 17.8% of cases it developed against the background of purulent bronchitis.

Haemagglutinating inhibiting antibody (HAI) responses were determined and clinical reactions recorded in 162 adult volunteers who received either 1 or 2 intranasal doses of 10(7-0) EID50 WRL 105 strain live influenza vaccine or placebo. After administration of a single dose of vaccine significant antibody responses were obtained in 69 (70%) of 98 volunteers with initial antibody titres of less than or equal to 1/20. Of the 70 volunteers who received a second dose of vaccine, 62 provided a further post-vaccination sample of serum, and only 3 (4-8%), who had not responded to the first dose of vaccine, produced a significant antibody response. Local, upper respiratory and constitutional symptoms were recorded more frequently after the administration of a first dose of vaccine than after placebo or a second dose of vaccine. The symptoms were of a minor nature except in one volunteer who, after the first dose of vaccine, developed influenzal symptoms followed by bronchitis.

57 cases of common cold, influenza, acute tonsillitis and acute bronchitis were treated by rapid needling with filiform needles at Dazhui (Du 14), Fengchi (GB 13), and Quchi (LI 11). The indices for observation were first determined, and the 19 cases that manifested an axilla temperature drop of over 1 degree C after treatment and a ratio of < 0.3 of the main symptom scores after treatment were regarded as markedly effective; the 27 cases that manifested an axilla temperature drop of 0.5-1.0 degree C and a symptom score ratio of 0.3-0.6 were regarded as effective, and the 11 cases that manifested an axilla temperature drop of < 0.5 degrees C and a symptom score ratio of > 0.7 were regarded as failures. The total effective rate was 80.7%. Analysis of the individual patients indicated that the peripheral blood leucocyte and lymphocyte counts differed insignificantly after needling, while the body temperature, rate of respiration, pulse, blood pressure and acupoint temperature all dropped, with a simultaneous increase in the percentage of T-lymphocytes. The immediate effects were especially marked in fevers due to exogenous wind and cold.
