Analysis of pulmonary microecology and clinical characteristics of patients carrying human herpesvirus.

ABSTRACT

Aim: To investigate the impact of human herpes virus (HHV) carriage on lung microbiota, and its correlation with clinical features and laboratory indicators in patients. Methods: Retrospective analysis was conducted on 30 outpatient lung infection cases, which were divided into HHV (n = 15) and non-HHV (n = 15) groups. mNGS detected microbial composition. Microbial diversity and abundance were tested using Shannon and Chao1 indices. Their relationship with laboratory indicators were explored. Results: Significant differences in microbial abundance and distribution were found between two groups (p < 0.05). Moreover, HHV group showed negative correlations (p < 0.05) between Prevotella, Porphyromonas, Streptococcus and basophil/eosinophil percentages. Conclusion: HHV carriage impacts lung microbiota, emphasizing the need for clinicians to pay attention to HHV reactivation in outpatient lung infection patients.

This study looked at how a common virus called human herpesvirus (HHV) affects the bacteria in our lungs. We wanted to see if HHV is linked to how sick we feel and what tests show. We split 30 people who had lung infections into two groups ­ 15 with HHV and 15 without ­ and checked how sick they felt, did some tests, and looked at the types of bacteria in their lungs. Both groups felt similarly sick and got better with medicine, but people with HHV had fewer of a certain type of blood cell. People with and without HHV also had different types of bacteria in their lungs. This study helps us understand why people get sick with lung infections and how to make them better. It might also help doctors decide how to treat people with lung infections.
