About this study
Official title: Correlation Between Vitamin D and Symptoms Severity of Autonomic Nervous Mediated Syncope（NMS） Child and it 's RAAS
children ; autonomic nervous mediated syncope； vitamin D ; symptom score ; renin-angiotensin-aldosterone-system
Read the detailed description
children with autonomic nervous mediated syncope have seriously affects children's physical and mental health and quality of life, and the incidence rate is also increasing year by year. But the current treatment measures are not ideal, Therefore, we need to look for new biological indicators, according to different biological indicators to develop different treatment options, so as to improve the current situation of poor treatment of children with NMS

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Vitamin D and Full automatic chemiluminescence measuring instrument in people with Vitamin D, run by Kongyujie at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact yujie Kong, M.D (18709316966, 13523396714@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Vitamin D levels (time frame: 3 months after taking the drug). 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 5 Apr 2022; AzTrials last refreshed its copy on 7 Nov 2026.
