Dynamic Alterations of Th2/Th1 With New Onset of Community-acquired Severe Sepsis Patients

August 19, 2018 updated by: Jianfeng Xie

Dynamic Alterations of Th2/Th1 With New Onset of Community-acquired Severe Sepsis

To evaluate the dynamic alterations of Th2/Th1 for the prediction of clinical immunity and how it was related to 28 day-prognosis and ICU-acquired infections among critically ill patients of community-acquired severe sepsis with new onset.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

We enroll patients with community-acquired severe sepsis and then the patients admitted to ICU without the diagnosis of severe sepsis as ICU control group, and the heathy volunteers as healthy control group.

Description

For community-acquired severe sepsis group:

Inclusion Criteria:

  • at least 18 years of age and no more than 90 years of age
  • sepsis was defined according to consensus criteria
  • diagnosis of sepsis and complicatied with organ dysfunction no longer than 48 h
  • provided written informed consent.

Exclusion Criteria:

  • diagnosis of hematological,immunological disease or cancer
  • treatment with chemotherapy agents or corticosteroids within 6 months prior to or during the hospitalization

For non-severe sepsis ICU control group:

Inclusion Criteria:

  • at least 18 years of age and no more than 90 years of age
  • without diagnosis of sepsis and admitted to ICU
  • provided written informed consent.

Exclusion Criteria:

  • diagnosis of hematological,immunological disease or cancer
  • treatment with chemotherapy agents or corticosteroids within 6 months prior to or during the hospitalization

For healthy control group:

Inclusion Criteria:

  • at least 18 years of age and no more than 90 years of age
  • provided written informed consent.

Exclusion Criteria:

  • diagnosis of hematological,immunological disease or cancer
  • treatment with chemotherapy agents or corticosteroids within 6 months prior to enrollment

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Comunity-acquired severe sepsis patients
Patients with new-onset community-acquired severe sepsis within 24h without confounding factors in immune status
Non-severe sepsis patients
Patients between 18 and 90 years of age and be admitted to the ICU without a diagnosis of severe sepsis.
Healthy controls
Heathy vonlunteers between 18 and 90 years of age.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Th2/Th1 upon enrollment
Time Frame: Day 0 after enrollment for community-acquired severe sepsis group and Day 0 after enrollment for the non-severe sepsis patients and heathy control group
The blood samples were collected for T helper 1 cells and T helper 2 cells populations measured by flow cytometry. All groups are needed.
Day 0 after enrollment for community-acquired severe sepsis group and Day 0 after enrollment for the non-severe sepsis patients and heathy control group
Th2/Th1 on Day 3
Time Frame: Day 3 after enrollment for community-acquired severe sepsis group
populations measured by flow cytometry. Only community-acquired severe sepsis group is needed.
Day 3 after enrollment for community-acquired severe sepsis group
Th2/Th1 on Day 7
Time Frame: Day 7 after enrollment for community-acquired severe sepsis group
populations measured by flow cytometry. Only community-acquired severe sepsis group is needed.
Day 7 after enrollment for community-acquired severe sepsis group

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
28-day mortality for community-acquired severe sepsis group
Time Frame: 28-day
28-day
ICU-acquired infection for community-acquired severe sepsis group
Time Frame: 28-day
28-day

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2014

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
July 20, 2018

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
