Gut Microbiota and Sepsis-associated Acute Kidney Injury (GMASAKI)

January 30, 2023 updated by: First Affiliated Hospital Xi'an Jiaotong University

The Relationship Between Gut Microbiota and Sepsis-associated Acute Kidney Injury in Sepsis Patients：Multicenter Observational Study

Sepsis has emerged as one of the important life-threatening infectious diseases with high morbidity and mortality. Sepsis-associated kidney injury (SAKI) is one of the most common and serious complications of sepsis. It has been found that intestinal flora may affect the occurrence and development of a variety of diseases, and may also affect the pathogenesis of multiple SAKI, which is also regulated by host genetic factors. Therefore, the investigators speculate that gut microbiota composition may be associated with susceptibility to SAKI, and there are no studies reporting the association between gut microbiota and SAKI. The investigators intend to carry out a multicenter study in conjunction with the Department of Intensive Care of Qinghai Provincial People's Hospital. The structure and function of intestinal flora in septic patients with renal injury and septic patients less susceptible to renal injury are studied by 16S rDNA amplicon sequencing technology. The differences in composition, diversity and structural stability of intestinal flora between the two groups are analyzed to explore the genera that play a key role in the occurrence of the disease. By analyzing the differences between renal injury and inflammation levels in each group, the correlation between intestinal flora and SAKI, the possible influencing links involved, and the related factors affecting the prognosis of SAKI were revealed. The results of this study are helpful to further elucidate the pathogenesis of SAKI and provide new ideas and methods for the prevention and treatment of SAKI.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Sepsis patients who met the inclusion criteria were admitted to the First Affiliated Hospital of Xi'an Jiaotong University and Qinghai Provincial People 's Hospital during the study period.

Description

Inclusion Criteria:

  • Age≥18 years；Meet the sepsis definition and diagnostic criteria of Sepsis-3.0 guidelines；No previous history of hypertension or diabetes; No underlying kidney disease such as nephrotic syndrome, no history of rheumatic immune system disease; Normal renal function before onset.

Exclusion Criteria:

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
Differences in gut microbiota composition between the two groups
Time Frame: Within 24 hours of patient enrollment
The differences in the composition of intestinal flora between the two groups were analyzed to identify the correlation with AKI
Within 24 hours of patient enrollment

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
Measure Description
Time Frame
IL-6
Time Frame: Within 24 hours of patient enrollment
the concentration of Interleukin 6 (IL-6)
Within 24 hours of patient enrollment
