Community acquired pneumonia of viral-bacterial etiology in young people: actual aspects of clinical and laboratory diagnostics

Abstract

Community acquired pneumonia is one of the most topical acute respiratory diseases, which is caused by high incidence rate, especially in organized groups of people, constantly changing microbial flora, the increasing resistance of bacteria to antibacterial drugs, difficulties in etiological diagnostics, and the possibility of life-threatening complications and fatalities. An innovative algorithm of etiological diagnostics of community acquired pneumonia is suggested, which includes immunochromatography express-tests of sputum for viruses detection, bacteriological sputum culture, immunoenzyme assay of blood and polymerase chain reaction of sputum and blood serum. It is shown that standard bacteriological sputum culture did not allow us to reveal causative agents of community-acquired pneumonia timely and precisely in most cases, whereas the application of more comprehensive etiological diagnostics enabled us to reveal the causative agent in the majority of the examined patients. And express methods provided an opportunity to verify the infectious agent within 1-2 days and administer early effective etiotropic treatment. It is demonstrated that modern community acquired viral bacterial pneumonia has a number of clinical and laboratory features depending on the revealed viral agents. These features may be used as additional diagnostic criteria of the disease, especially when modern methods of etiological diagnostics are unavailable. The obtained results showed the effectiveness of the use of immunochromatography express-tests of sputum, polymerase chain reaction of sputum and blood serum, and immunoenzyme assay of blood. As a result of statistical analysis, a number of characteristic clinical and laboratory predictors of certain viral-bacterial associations of modern community acquired pneumonia was determined.
