Brief Summary:


Hyperprolactinemia(HPRL) which can result in a series of prolactin-related symptoms is a frequent adverse effect of antipsychotics. The investigators are interested to explicate the characteristics of serum prolactin level change after taking different antipsychotics and related factors.


  1. Review of electronic medical records of schizophrenia patients who were brought to Shanghai Mental Health Center since January 1, 2007.
  2. The investigators collect their information, and then

    1. set serum prolactin level after first 1-month antipsychotic treatment as primary outcome. Secondary outcomes are prolactin levels tested at other time points.
    2. 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.
    3. 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.

Drug Information available for: Prolactin

Intervention Details:
  • Drug: Antipsychotic
    any antipsychotic medicine that would have the effect on prolactin level, such as amisulpride, risperidone, olanzapine and so on.

Primary Outcome Measures :
  1. prolactin level at first 1-month antipsychotic treatment [ Time Frame: at first 1-month antipsychotic treatment ]
    Serum prolactin level may change significantly after one month antipsychotic treatment.

Secondary Outcome Measures :
  1. prolactin level at other time points [ Time Frame: after 2-month, 3-month and half a year treatment with antipsychotics ]
    Different patients have different tendencies of prolactin, so collecting prolactin level at different time after exposed to antipsychotics is necessary.
