Brief Summary

Schizophrenia is a severe mental illness that seriously affects the health and functioning of patients. Previous studies have found immunoinflammatory abnormalities in the blood, cerebrospinal fluid, central nervous system, and neuroimaging of people with schizophrenia, along with therapeutic effects of anti-inflammatory drugs on schizophrenia. These evidences suggest a close relationship between schizophrenia and immunity and inflammation. Therefore, we consider that the state of immune inflammation is a potential subtype classification basis for schizophrenia, and hypothesize that immune classification based on peripheral-central multidimensional data is related to patient's response to medication and cognition.

Outcome Measures

Primary Outcomes (7)

  • Change of clinical symptoms by PANSS

    The change of PANSS at different follow up timepoint (lower score means a better outcome).

    baseline, 1st month, 3rd month

  • Change of the MCCB score

    After assessment at each visit, evaluator convert raw scores to scale scores, then to normalized T scores. T scores of seven domains and composite score are further calculated. Compare the intergroup differences and longitudinal changes of the MCCB score between patients with schizophrenia and healthy volunteers, as well as patients with different clinical subtypes.(higher scores mean a better outcome.)

    baseline, 1st month, 3rd month

  • Changes of MRI

    Compare the intergroup differences and longitudinal changes in brain structure, function, DTI, and QSM between patients with schizophrenia and healthy volunteers, as well as patients with different clinical subtypes.

    baseline, 1st month, 3rd month

  • Changes of peripheral and central inflammatory factors

    Compare the levels and longitudinal changes of inflammatory factors in cerebrospinal fluid and blood between patients with schizophrenia and healthy volunteers, as well as patients with different clinical subtypes.

    baseline, 1st month, 3rd month

  • Changes of autoantibody

    Compare the levels and longitudinal changes of autoantibody in cerebrospinal fluid and blood between patients with schizophrenia and healthy volunteers, as well as patients with different clinical subtypes.

    baseline, 1st month, 3rd month

  • Changes of peripheral immune cells

    Compare the intergroup differences and longitudinal changes of immune cells in the blood between patients with schizophrenia, healthy volunteers, and patients with different clinical subtypes.

    baseline, 1st month, 3rd month

  • EEG physiological detection index

    Detect resting state and task state EEG, analyze and calculate each bandwidth of the EEG (e.g. Alpha, Beta, Theta, etc.) and the functional E/I ratio of EEG power spectrum.

    baseline, 1st month, 3rd month

Secondary Outcomes (9)

  • Changes of other biological indicators

    baseline, 1st month, 3rd month

  • Change of clinical symptoms by Clinical Global Impression

    baseline, 1st month, 3rd month

  • Change of social function by Personal and Social Performance Scale

    baseline, 1st month, 3rd month

  • Change of Body Mass Index

    baseline, 1st month, 3rd month

  • Change of the level of blood lipids

    baseline, 1st month, 3rd month

  • +4 more secondary outcomes

Study Arms (2)

Individuals with schizophrenia

Inclusion Criteria: 1. Clinical diagnosis that meets ICD-11 criteria for schizophrenia. 2. Confirmation of the diagnosis of schizophrenia using the SCID-5-RV. Exclusion criteria: 1. Clinical diagnosis or SCID-5-RV assessment confirming neurodevelopmental disorders, bipolar and related disorders, substance use disorders (excluding alcohol and tobacco). 2. Presence of severe or acute physical illnesses, including traumatic brain injury, intracranial space-occupying or infectious diseases, acute cardiovascular diseases, acute respiratory system diseases, acute hematological disorders, autoimmune disease, etc. 3. Presence of clearly defined genetic diseases, including tuberous sclerosis, multiple sclerosis, Kleefstra syndrome, 22q11.2 deletion syndrome, Prader-Willi syndrome, Klinefelter syndrome (47, XXY), etc.

Other: Regular follow-up assessments without intervention.

Healthy volunteers

1. No diagnosis of any mental disorder. 2. First degree relatives without mental disorders. Exclusion criteria are the same as for the schizophrenia patient group.

Other: Cross-sectional assessment

Interventions

Participants will receive a 3-month follow-up with clinical information, biological samples, and imaging data collected at baseline, 1st and 3rd months. The baseline assessment will include demographic information, medical history and previous medication use. At baseline and follow-up, patients' physical examination data (height, weight, waist and hip circumference, etc.), clinical symptom assessment scales (PANSS, SANS, SAPS, CDSS, CPSS, CGI, GAF, PSP, and SAS) and MCCB cognitive assessment data, blood and cerebrospinal fluid samples, MRI, and EEG data will be collected. Collection and store of blood and cerebrospinal fluid samples for routine laboratory tests and multi-omics including immunohistology, inflammation-related molecules, single-cell sequencing, extracellular vesicles, and other assays.

Individuals with schizophrenia

Volunteers' physical examination data (height, weight, waist circumference, hip circumference, etc.), scale assessments (SCID, SCL-90, and CPSS) and MCCB cognitive assessment data, blood samples, MRI, and EEG data will be collected. Blood was collected and stored for exploring differences between patients and healthy individuals.
