About this study
Official title: Prolactin Change and Its Effectors in Chinese Patients With Schizophrenia After Antipsychotics Treatment

Method:
- Review of electronic medical records of schizophrenia patients who were brought to Shanghai Mental Health Center since January 1, 2007.
- The investigators collect their information, and then
- set serum prolactin level after first 1-month antipsychotic treatment as primary outcome. Secondary outcomes are prolactin levels tested at other time points.
- Variables will range from antipsychotic kinds, dosage, treatment duration and blood concentration to demographic information, to disease history, to clinical treatment on hyperprolactinemia, to laboratory test results, such as blood routine examination, biochemistry, sex hormone levels and so on.
- After data cleaning and management, we will apply logistic regression, cox regression, Receiver Operating Characteristic curve (ROC) and machine learning to
- analyze factors of prolactin level;
- establish a model of prolactin change with time;
- propose optimal monitoring time of prolactin according to prolactin change with time;
- analyze correlation among antipsychotics, prolactin and clinical characters, for the purpose to supply objective evidence for antipsychotic treatment.
- Conditions
- Schizophrenia, Antipyretics Toxicity, Prolactin Excess
- Being tested
- Antipsychotic
- Medical subject headings
- Schizophrenia, Hyperprolactinemia
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AntipsychoticDrug
any antipsychotic medicine that would have the effect on prolactin level, such as amisulpride, risperidone, olanzapine and so on.
What is being measured
The primary outcome is the main question the study is designed to answer.
prolactin level at first 1-month antipsychotic treatment
Serum prolactin level may change significantly after one month antipsychotic treatment.
Measured: at first 1-month antipsychotic treatment
Secondary outcomes (1)
prolactin level at other time points
Different patients have different tendencies of prolactin, so collecting prolactin level at different time after exposed to antipsychotics is necessary.
Measured: after 2-month, 3-month and half a year treatment with antipsychotics

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04002258, which also lists 1 linked publication.
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.
