About this study
Official title: A Prospective Observational Study: Connection Between Vitamin D Level and the Efficacy of Dexamethasone in Immune Thrombocytopenia
The project was undertaking by Qilu Hospital of Shandong University in China. The objective is to find out if there is a connection between vitamin D level and the efficacy of dexamethasone for the treatment of adults with newly-diagnosed primary immune thrombocytopenia (ITP).
Read the detailed description
The investigators anticipate to undertaking a prospective, observational，non-randomized control trial of 60 ITP adult patients. Dexamethasone (given orally at a dose of 40 mg per day for 4 days, two-cycles with an interval of 10 days) will be used in the target patients. Vitamin D level will be detected before the utilization of treatment measures. Depend on the vitamin D level, the patients will be divided into 2 groups(higher vitamin D level group and lower vitamin D level group).Platelet count, bleeding and other symptoms were evaluated before and after treatment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexamethasoneDrug
HD-DXM (orally at 40 mg daily for 4d )
| Study group | Role | What they receive |
|---|---|---|
| Lower vitamin D level group | The vitamin D level is lower than 20 nmol/L. Receives: Drug: Dexamethasone | |

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sustained response to ITP treatments (time frame: 3 months after treatment started). 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 9 Sep 2020.
