G6PD Deficiency in Infarction Patients in Shaanxi Province (GPS-IP)

April 28, 2022 updated by: First Affiliated Hospital Xi'an Jiaotong University

Prevalence of G6PD Deficiency in Cerebral Infarction Patients and the Correlation With Prognosis in Shaanxi Province

Cerebral infarction brings heavy burden to patients and families with high morbidity, mortality, disability and recurrence rate. Anti-platelet aggregation therapy plays important role for secondary prevention of cerebral infarction. G6PD deficiency is a rare genetic disorder, patients with this disorder could suffer hemolysis after eating broad beans. Professor Zeng Jinsheng et al found that the hemolysis risk of G6PD deficiency patients was significantly increased when aspirin was applied in Guangdong Province. However, the prevalence of G6PD deficiency in northern China remains unknown, as well as the safety of antiplatelet therapy. To this end, 1000 patients with acute cerebral infarction will be continuously included in 30 second-level and above hospitals in 10 prefectures and cities of Shaanxi Province for observation and follow-up for 12 months, to explore the prevalence of G6PD deficiency in cerebral infarction patients in Shaanxi Province, and to analyze the relationship between G6PD deficiency and the clinical characteristics and prognosis of cerebral infarction. To clarify the efficacy and safety of antiplatelet therapy for G6PD patients with cerebral infarction is of great significance for guiding the individualized treatment of cerebral infarction.

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

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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 80 years (Adult, Older Adult)

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.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
G6PD Deficiency
In the laboratory of the First Affiliated Hospital of Xi 'an Jiaotong University, tetrazolazole-blue quantitative method will be used to detect G6PD. According to the normal range of the tetrazole-blue quantitative method (6.8-20.5NBT), adults with G6PD activity < 6.8NBT were positive, and G6PD deficiency is confirmed.
Genetic: G6PD gene deficiency
we will use tetrazolazole-blue quantitative method to detect whether the patient suffer from G6PD deficiency.
Normal
The G6PD activity ranged from 6.8 to 20.5 NBT and the G6PD activity is normal.

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
Prevalence of G6PD deficiency
Time Frame: up to 24 weeks
Prevalence of G6PD deficiency in cerebral infarction patients in Shaanxi Province
up to 24 weeks

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
National Institute of Health stroke scale
Time Frame: 1 year
on a scale of 0-42, the higher the score, the more damage of the nervous system
1 year
All-cause mortality rate
Time Frame: 1 year
All-cause mortality was calculated in % for both groups
