Association of Copy Number Variations in the SMN Genes With Acute Kidney Injury After Heart Surgery

May 9, 2020 updated by: Xinhua Hospital, Shanghai Jiao Tong University School of Medicine

Molecular Epidemiology Study of the Association of Copy Number Variations in the SMN Genes With Acute Kidney Injury After Heart Surgery

This prospective cohort study aims to explore the susceptibility to acute kidney injury after heart surgery in SMN1+/- genotype population. This study also aims to analysis the effect of SMN1+/- genotype on postoperative AKI and the development of chronic kidney disease, as well as dose-compensating effect of different copy number of SMN2 gene on SMN1 +/- genotype.

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.

Detailed Description

This prospective cohort study aims to explore the susceptibility to acute kidney injury after heart surgery in SMN1+/- genotype population. Real-time PCR is used to detect copy number variations in the peripheral blood SMN gene on 1206 patients with heart surgery. This study also aims to analysis the effect of SMN1+/- genotype on postoperative AKI and the development of chronic kidney disease, as well as dose-compensating effect of different copy number of SMN2 gene on SMN1 +/- genotype.

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

1 month to 80 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients from Xinhua Hospital, Shanghai Jiao Tong University School of Medicine

Description

Inclusion Criteria:

  • Age: Children (1 month -17 years old) and adults (18-80 years old);
  • Sex: All;
  • Those who will receive selective cardiac surgery with cardiopulmonary bypass;
  • Those who signed the informed consent.

Exclusion Criteria:

  • Those with glomerular filtration rate: eGFR<15ml/min/1.73m2, and those who have received the renal replacement therapy before surgery;

Design Details

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
Number of participants with occurrence of acute kidney injury (AKI) after cardiac surgery
Time Frame: 48 hours
The definition of the occurrence of acute kidney injury is according to the acute kidney injury (AKI) definition and staging criteria released by Kidney Disease: Improving Global Outcomes (KDIGO) in the year 2012
48 hours

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
Number of participants with occurrence of acute kidney disease (AKD) after cardiac surgery
Time Frame: 3 months
The definition of the occurrence of acute kidney disease is according to the acute kidney disease (AKD) definition criteria released by Kidney Disease: Improving Global Outcomes (KDIGO) in the year 2012
3 months
Glomerular Filtration Rate(GFR)
Time Frame: 90 days
Glomerular filtration rate (GFR) is defined as the volume of plasma that is filtered by the glomeruli per unit of time, and is usually measured by estimating the rate of clearance of a substance from the plasma.

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.
April 1, 2020

Primary Completion (Anticipated)

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.

Study Completion (Anticipated)

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.
