Neuroendocrine and Metabolite Substrates in Schizophrenia
Neuroendocrine, Metabolite Substrates, Clinical Symptoms and Cognitive Function in Schizophrenia
Background: Schizophrenia is a serious mental illness. The diagnosis and severity evaluations of schizophrenia are generally based on patient behaviors. Biomarkers are objectively measured and used as indicators for diagnosis confirmation, symptom assessment, and evaluation of pharmacologic responses to therapeutic interventions. Neuroendocrine and metabolite substrates are potential biomarkers of the pathogenic processes in schizophrenia.
Aims: The aims of this study are to determine (a) the differences in neuroendocrine and metabolite substrates between patients diagnosed with schizophrenia and healthy controls; and (b) the associations among the neuroendocrine and metabolite substrates, cognitive function, clinical symptoms, and treatment responses of patients diagnosed with schizophrenia.
Methods: (a) The investigators plan to recruit 100 patients diagnosed with schizophrenia and 100 healthy controls as participants. (b) At the baseline and Week 12, patient blood samples will be obtained to measure the levels of neuroendocrine substrates and metabolite markers. Clinical symptoms and cognitive function will be evaluated. (c) For the healthy control participants, blood samples will be obtained once to measure neuroendocrine and metabolite marker levels.
Expected Results: The results of this study may contribute to identifying potential neuroendocrine and metabolite biomarkers of schizophrenia, and clarify the associations among the neuroendocrine and metabolite substrates, cognitive function, clinical symptoms, and treatment responses of patients diagnosed with schizophrenia. Such information is crucial for clinical evaluations and future research.

Detaljert beskrivelse
- The investigators plan to recruit 100 patients with schizophrenia and 100 healthy control subjects.
- For the patients, diagnoses of schizophrenia will be confirmed using the Chinese version of the Mini International Neuropsychiatric Interview (MINI). At the baseline and Week 12, patient blood samples will be obtained to measure the levels of neuroendocrine substrates (didehydroepiandrosterone, dehydroepiandrosterone sulfate, pregnenolone, and cortisol) and metabolite markers (lipid profiles, glycerate, eicosenoic acid, pyruvate, b-hydroxybutyrate, Cysteine). Cognitive function will be evaluated using the Brief Assessment of Cognition in Schizophrenia. The participants' clinical symptoms and daily activities will be assessed using the Positive and Negative Syndrome Scale, 17-item Hamilton Depression Rating Scale, and Personal and Social Performance Scale.
- For the healthy control subjects, psychiatric diagnoses will be verified using MINI, and blood samples will be obtained once to measure neuroendocrine and metabolite marker levels.
