Abstract

The article discusses the problem of cytomegaloviral persistence asymptomatic course among young patients with community-acquired pneumonia and in healthy population group based on specific immunoglobulins M and G appearance in blood and antibody avidity value (the duration of persistent). The connection between viral persistence and prognosis of community-acquired pneumonia course (by pneumonia severity index in PORT) is also recognized.

Aim of the scientific work is to study the prevalence of cytomegaloviral persistence among young patients with community-acquired pneumonia for optimization the plan of clinical examination and prognosis for this patient category.

Materials and methods. One hundred and five patients with community-acquired pneumonia and 61 healthy individuals (aged from 18 to 44 years) were examined for cytomegaloviral biomarkers (CMV IgG, CMV IgG avidity) and by PORT-scale. Positive result for viral persistence was compared with gender, age subtypes and pneumonia severity index in both groups.

Results. Cytomegaloviral persistence prevalence rate among patients with community-acquired pneumonia was 48.2 % versus 20.5 % among healthy individuals (p = 0.003). The patients with community-acquired pneumonia had higher CMV IgG avidity value (p = 0.007), it was more common for female patients (P = 0.043; χ2 = 8.164). The cytomegaloviral persistence prevalence increased with age (P = 0,045) and correlated with pneumonia severity index according to PORT-scale (P < 0.0001).

Conclusions. The patients with community-acquired pneumonia differ in significantly higher cytomegaloviral prevalence rate (P = 0.003) from the healthy respondents. This rate increases with age, negatively impacts the pneumonia prognosis (by PORT-score). The duration of cytomegaloviral persistence (based on the CMV IgG avidity value recognition) does not depend on age in both comparison groups (P > 0.05).
