Summary
Patients with attack-like schizophrenia (ALS) show elevated markers of vascular endothelial cell dysfunction, including leukocyte elastase (LE), von Willebrand factor (WF), and C-reactive protein (C-RP). These findings suggest a vascular lesion in the blood-brain barrier of ALS patients.
Area of Science:
- Neuroscience
- Vascular Biology
- Psychiatry
Background:
- Schizophrenia is a complex psychiatric disorder with potential links to neuroinflammation and vascular abnormalities.
- Vascular endothelial cell (EC) dysfunction is increasingly recognized as a contributing factor in various neurological and psychiatric conditions.
Purpose of the Study:
- To investigate markers of EC dysfunction and inflammation in patients with attack-like schizophrenia (ALS).
- To explore the relationship between these markers and clinical symptom severity in ALS.
Main Methods:
- Blood plasma samples were collected from 22 male patients with ALS and 24 matched controls.
- Leukocyte elastase (LE) activity, von Willebrand factor (WF), and C-reactive protein (C-RP) were measured as indicators of EC dysfunction and inflammation.
Main Results:
- Patients with ALS exhibited significantly higher levels of WF, C-RP, and LE compared to controls.
- Positive correlations were observed between LE activity and WF concentrations.
- WF levels were positively correlated with the severity of clinical symptoms in ALS patients.
Conclusions:
- The findings indicate EC dysfunction and/or lesion in the vasculature of ALS patients.
- The observed correlations suggest a potential vascular layer lesion of the blood-brain barrier in ALS schizophrenia.
- These results highlight the importance of vascular factors in the pathophysiology of ALS.
