“…Such statistics among elderly population is explained as a result of chronic internal comorbidities influence into the fatal outcome of CAP. [3] The risk CAP factors among young population (18–44 years old according to the World Health Organization Classification) are controversial and are on the hypothesis stage. persistent asymptomatic diseases create an immunological basis for the attachment of the bacterial microflora and due to immunosuppression, worsen the course of CAP.…”

Objectives: The aim of this study was to determine the predictive role of TLR4 polymorphism in CAP course among young cytomegalovirus-positive patients. Subjects and Methods: One hundred and five patients with pneumonia (age range: 18–44 years) and 61 healthy respondents were observed clinically and specifically (by cytomegalovirus markers and TLR4 + 3725 G/C polymorphism). Results: Among CAP patients, there were 51 male (48.6%) and 54 female (51.4%), with average age 34.1 ± 0.8 years, and there were 19 (18.1%) patients with Pneumonia Patient Outcomes Research Team (PORT) I, 46 (43.8%) patients with PORT II, 31 (29.5%) patients with PORT III, and 9 (8.6%) patients with PORT IV. Cytomegalovirus persistence was detected in 80 (48.2%) patients and 34 (20.5%) healthy respondents ( P = 0.003). G/G genotype of TLR4 signaling was found in 78 (74%) patients with pneumonia, G/C in 24 (23%) patients, and C/C in 3 (3%) patients. Among G/C patients, there were 16.2% cytomegalovirus-positive patients versus 6.7% negative patients ( P < 0.05), as well as among G/G patients, and there were 59% versus 15,2%, accordingly ( P < 0.01). The patients of the main group with G/G genotype were characterized by mostly mild (PORT I – 15 [14.3%]) and moderate pneumonia severity (PORT II – 32 [30.5%] and PORT III – 26 [24.8%] patients). The patients with G/C genotype were characterized by mostly PORT II (11 [10.5%] patients). All C/C genotype patients have PORT II ( P < 0.05). Conclusions: Cytomegalovirus persistence worsens the pneumonia course. G/G and G/C TLR4 genotypes are associated with mild pneumonia severity.
