WRL 105 strain live influenza vaccine or placebo was given to patients with chronic bronchitis in a double-blind study. The twenty-one vaccinated and twenty-three placebo-treated patients made daily self-assessments of the severity of symptoms of cough, breathlessness, tightness, wheeze, and sputum production in the following 20 weeks. Symptom scores in the first 2 weeks after vaccination or treatment with placebo were used to calculate a baseline range for each patient. Comparison of symptoms in the two groups in the baseline period showed that symptoms were more often reported by vaccinated than by placebo-treated patients but the differences were not statistically significant. One patient who responded serologically to vaccination had a moderately severe influenzal illness starting on the day after vaccination. Comparison of symptom scores during the 18-week surveillance period with baseline values showed that symptoms of breathlessness, tightness, wheeze and cough were significantly more common in vaccinated than in placebo-treated patients and that antibiotic usage was more common in the vaccinated group.

An epidemic of influenza B began in January, 1977, in two rural parishes in northeastern Louisiana and quickly spread to involve 29% of their population with clinical influenza. This epidemic was investigated using a standard questionnaire and a random sample of 4.2% of the population. The clinical illness was typical of influenza, with predominant fever, cough, malaise and headache. Gastrointestinal symptoms were part of the clinical syndrome. Rhinitis and diarrhea were significantly more common in children aged five years or less. Clinical attack rates increased with larger household size. The youngest age groups had clinical attack rate of 40--55%, but the elderly had very low attack rates. The direct cost of influenza-like illness during the epidemic averaged almost $30.00 per case. Knowledge of the cost of influenza-like illness and age-specific attack rates should be useful in planning future control efforts for influenza B.

A consecutive series of 282 nurses of the University Hospital, Groningen, with complaints of the nose and/or throat associated with coughing and/or hoarseness were examined between April 1965 and February 1968. The intent was to obtain information on the incidence of viral, mycoplasma and bacterial infections, and on the relationship of these infections in nurses with chronic nonspecific lung disease (CNSLD). The following results were obtained: 1. Virus infections caused by influenza virus (A, B, and C), rhinovirus, parainfluenza virus, adenovirus, respiratory syncytial virus and/or Mycoplasma pneumoniae were confirmed in 30% of the nurses examined; if influenza was excluded, this figure was 20%. 2. Rhinovirus infections were found more often than all the other virus infections together (if influenza was excluded). 3. Approximately 25% of the nurses had signs of CNSLD. 4. In the course of the virus infections, nine out of 14 nurses with a history of chronic obstructive lung disease showed symptoms of exacerbation or recurrence of a generalized bronchial obstruction. 5. There was no difference in the incidence of virus infections in the group of nurses with and without CNSLD. 6. There were more bacterial infections (without a confirmed virus infection) in the subjects with CNSLD than in those without CNSLD. 7. There were more combined viral/bacterial infections in the patients with CNSLD than in those without CNSLD. 8. Patients with influenza did not have more bacterial infections than patients with other virus infections. This is also true for patients with CNSLD and influenza when regarded separately. The patients without CNSLD tended to have more bacterial infections with influenza than with other viral infections, but the difference was not statistically significant.

A 40-year-old woman who had recently undergone kidney transplantation was succesfully treated for diffuse influenza virus pneumonia. The illness was acute, with rapid onset, high fever, nonproductive cough, dyspnea, cyanosis, crepitations and rales over both lung bases, and associated arterial hypoxemia, leukopenia, and thrombocytopenia. Prophylactic use of antibiotics to prevent superimposed bacterial infection and reduction of immunosuppressive therapy to minimal dosage during the critical phase of the respiratory infection contributed to the patient's survival. An episode of graft rejection was reversed by resumption of immunosuppressive therapy at standard dosage levels.

To determine whether a model could be established for laboratory investigations, nine squirrel monkeys were inoculated intratracheally with 10(7) median egg-infectious doses of influenza virus type A/New Jersey/8/76 (HSW1N1) (swine influenza virus). They responded with clinically detectable illness including fever, leukopenia, decreased food consumption, increased respiratory rate, occasional coughing, labored breathing, nasal discharge, and lethargy. Convalescence was well advanced by the day 10. All monkeys excreted virus for 7 to 8 days. A scoring procedure (illness score) has been developed for use in studies of vaccine and chemotherapeutic efficacy.

To assess the relative effect of natural versus experimental influenza illness on pulmonary function, we compared 43 normal adults with documented nonpneumonic influenza A infection during three outbreaks, 1974 (A/Port Chalmers/74), 1975 (A/Port Chalmers/74), and 1976 (A/Victoria/75) to 24 normal volunteers following nasal inoculation with wild-type influenza A/England/42/72, A/Scotland/74 or A/Victoria/75. In naturally acquired illness, abnormalities in small airway functiion and transiently increase airway reactivity were observed. In contrast, no such dysfunction was observed in experimentally induced illness. This group manifested milder illness and significantly shorter duration of cough.

Seven well volunteers and three patients with a naturally occurring influenza A/USSR/77 (H1N1)-like infection were given amantadine by small-particle aerosol with a Collison generator modified for this purpose. Inhalation periods for the volunteers were increased on consecutive weekends from 15 min to 1 h, 4 h, 9 h, and 2 consecutive days of 6 h each. The particle size was 1.2-micrometer mass median diameter, and the concentration of inhaled aerosol ranged from 47 to 75 microgram/liter. Estimates of retained doses in 9 h were 74 to 149 mg. About two-thirds of the dose was recovered in the urine. Pulmonary function studies did not vary significantly from base-line values and were within a normal range for five of seven volunteers. Two volunteers with a moderate reduction in mid-maximal flow before exposure had a total of three episodes of coughing and wheezing associated with moderate reductions in mid-maximal flow values. These episodes cleared spontaneously or improved promptly after isoproterenol therapy. The patients with influenza tolerated the treatment well and recovered promptly.

The matched pair system of the Finnish Register of Congenital Malformations was used to search for association between defects of the central nervous system (CNS), and maternal diseases and/or drug consumption during pregnancy. The study material consisted of 710 cases with CNS defects and their controls. Significant associations were found for the following conditions: influenza, threatened abortion, depressive state, toxemia of pregnancy, diabetic mothers, and for the consumption of the following drugs: salicylates, pyrazolones/anilines, euphoristic analgesics, sympathomimetics, barbiturates, and cough medicines. 259 cases with polydactyly and their controls were also compared, with a view to demonstrating what biases might be introduced by the case-control method. After utilizing the possibilities of this design for examining the above mentioned significant associations, the factors to be seriously considered were reduced to the following ones: influenza, depressive state, toxemia of pregnancy, diabetic mothers and cough medicines.

Seronegative children undergoing primary infection sensitively reflect the residual virulence of an experimental attenuated respiratory vitral vaccine. Two temperature sensitive (ts) A/Hong Kong influenza vaccines derived following chemical mutagenesis of a cloned stock of A/Great Lakes/65 have been evaluated in vaccine trials in seronegative children. The two vaccines, ts-1[A] and ts 1[E], differ in their laboratory characteristics. Ts-1[A] has a lower shut-off temperature, 37 degrees C vs 38 degrees C, and more limited replication in the Syrian hamster model system than ts-1[E]. In A/HK seronegative adults ts-1[A] is noninfectious whereas ts-1[E] will replicate and induce an antibody response. The genetic lesion of ts-1[A] was stable in the young child; in contrast, late in the course of virus shedding, ts-1[E] exhibited genetic instability with 4 individuals shedding virus which had lost the ts marker. Transmission to controls was rare with both vaccines being observed in only 1 of 5 controls with ts-1[A] and none of six controls with ts-1[E]. There were no respiratory symptoms associated with ts-1[A] vaccine virus shedding. Ts-1[E] virus shedding had a suggestive association with fever and cough in the seronegative child. The trials in seronegative children extent and confirm the inherent differences between ts-1[A] and ts-1[E] vaccine strains and support the concept that laboratory markers of attenuation are predictive of vaccine behavior in the seronegative child.

The relationship of acute respiratory illness and infection to chronic bronchitis was investigated in the community of Tecumseh, Michigan. Families were randomly selected for study from among all those in the community and they were followed for periods of one year. Occurrence of acute respiratory illnesses was identified on a weekly basis. Frequency of chronic symptoms of cough and sputum production was separately ascertained. Lung function studies were performed three times during the course of the surveillance year and blood specimens were collected at those times. The blood specimens were tested for rise in antibody titer with antigens of type A and B influenza, respiratory syncytial virus and Mycoplasma pneumoniae. Adults with mild or intermittent chronic symptoms of cough and sputum production experienced more acute respiratory illness than those without these symptoms. This finding was present at different levels of smoking frequency. A similar relationship was present when serologic infection rates were used in the analysis instead of acute illness incidence. When the population was dichotomized on the basis of lung function data, the segment of the population with more depressed values was found to have experienced higher infection rates. The results suggest that acute infection may play an independent role in the pathogenesis of chronic respiratory disease.
