About this study
The goal of this observational study is to describe the immune signature of acute pulmonary infection.The main questions it aims to answer are:
- Nasal mucosal immune response in patients with influenza infection
- Difference of immune response between Viral sepsis and Bacterial sepsis
- Immunological differences between Viral sepsis and Viral pneumonia
Read the detailed description
- Aging could influence host immune response. Elderly people are more likely to progress to severe pneumonia than young people. Nasal mucosa is the initial infection site of influenza infection. Single cell sequencing of nasal mucosal cell that may provide valuable insights into host response to influenza infection.
- Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Although bacteria are considered as the main pathgens of sepsis，SARS-CoV-2 or influenza infection also can cause multiple organ dysfunction which meet the definition of Sepsis 3.0. Viral sepsis has not received enough attention for a long time. It is important to understand the difference between viral sepsis and bacterial sepsis that may help to develop better strategies to diagnose and treat sepsis.
- Viral pneumonia is one of the leading infectious cause of death woldwide.Pneumina is the most common cause of sepsis.The mechanism of viral pneumonia progressing to sepsis needs to be further investigated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
pathogenOther
Also called age
The patients were divided into groups according to the pathogen(bacteria or virus).
The influenza upper respiratory tract infection cohort will be grouped mainly according to age.
| Study group | Role | What they receive |
|---|---|---|
| Influenza upper respiratory infection | This cohort aims to descirbe the nasal mucosal immune response in influenza patients. We will collect nasal mucosal cells from influenza patients using Nasal Cytology Curettes. Blood samples will also be obtained from the patient. All samples will be used for single cell sequencing. Receives: Other: pathogen | |
| Viral Sepsis and Viral pneumonia | The purpose of this cohort is to characterize the immune pattern of patients with viral sepsis and find specific target for the treatment of viral sepsis. Blood samples will be obtained from the viral sepsis/pneumonia patients.All samples will be used for transcriptome sequencing. Receives: Other: pathogen | |
| Bacterial Sepsis and Bacterial pneumonia | This cohort served as a control for the viral sepsis/pneumonia cohort.Blood samples will be obtained from the bacterial sepsis/pneumonia patients.All samples will be used for transcriptome sequencing. Receives: Other: pathogen |

How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
upper respiratory infection or pneumonia or Sepsis (time frame: up to 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Nov 2022; AzTrials last refreshed its copy on 8 Nov 2026.
