Abstract:
The efficacy of aerosols of leukocytal interferon used in complex with antibacterial and other medicamentous agents was studied during influenza epidemic in 1975 due to Port-Chalmers virus of influenza A with increased numbers of viral-bacterial pneumonia. The viral-sta-phylococcal etiology of the infection was confirmed in 80 per cent of the cases under stationary conditions. Various microorganism and most often Staph aureus were isolated in addition to the viruses from the patient's sputum and washings and their antibioticograms were determined. The studies showed that the complex treatment of the patients with virologically and serologically confirmed diagnosis of the disease resulted in decreased duration of the disease, less pronounced intoxication and more rapid resorption of the changes in the lung tissue.
Insights
This study investigated leukocytal interferon aerosol combined with antibiotics for influenza A pneumonia. The combined treatment shortened illness, reduced toxicity, and improved lung healing in patients during a 1975 epidemic.
Area of Science:
- Virology
- Infectious Diseases
- Pulmonology
Background:
- Influenza A (Port-Chalmers virus) epidemic in 1975 featured increased viral-bacterial pneumonia.
- Viral-staphylococcal etiology confirmed in 80% of stationary cases.
- Staphylococcus aureus frequently co-isolated with influenza viruses.
Purpose of the Study:
- To evaluate the efficacy of leukocytal interferon aerosol in combination therapy for influenza A pneumonia.
- To assess the impact of combined treatment on disease duration, intoxication, and lung tissue changes.
Main Methods:
- Complex treatment involving leukocytal interferon aerosol, antibacterial, and other agents.
- Virological and serological confirmation of influenza A diagnosis.
- Isolation and antibioticogram determination of microorganisms from patient samples (sputum, washings).
Main Results:
- Combined therapy significantly decreased the duration of illness.
- Patients experienced less pronounced intoxication.
- More rapid resorption of lung tissue changes was observed.
Conclusions:
- Leukocytal interferon aerosol, as part of a complex treatment, is effective against influenza A pneumonia.
- This therapeutic approach improves clinical outcomes and radiological findings.
- The study highlights the importance of addressing both viral and bacterial components in pneumonia treatment.
