Impaired endothelial function in patients with psychotic disorders may contribute to increased cardiovascular mortality, but the mechanisms involved remain unclear. Here, we comprehensively analyzed endothelial function in 33 young (median age 18: IQR 17-27) patients diagnosed with first-episode psychosis (FEP), examining large vessels (flow-mediated dilation; FMD) and the microcirculation in peripheral vessels (peripheral arterial tonometry following reactive hyperemia; RH-PAT) and in the skin (flow-mediated skin fluorescence; FMSF). We also measured the plasma concentration of nitric oxide (NO) metabolites (nitrite/nitrate) and 18 biomarkers related to endothelial function, including those representative of glycocalyx damage (SDC-1), endothelial inflammation (sVCAM-1), disrupted endothelial permeability (Angpt-1, Angpt-2), and hemostasis (TAFI, THBS-1).

The global prevalence of overweight and obesity is a significant public health concern that also largely affects women of childbearing age. Human epidemiological studies indicate that prenatal exposure to excessive maternal weight or excessive gestational weight gain is linked to various neurodevelopmental disorders in children, including attention deficit hyperactivity disorder, autism spectrum disorder, internalizing and externalizing problems, schizophrenia, and cognitive/intellectual impairment. Considering that inadequate maternal body mass can induce serious disorders in offspring, it is important to increase efforts to prevent such outcomes.

Article Synopsis
  • The study emphasizes the need for a personalized approach to schizophrenia due to its polygenic nature, seeking laboratory biomarkers from various sources including blood, brain imaging, and patient self-reports.
  • Metabolomics research involving serum samples from patients and healthy volunteers identified three key biochemical indicators—cortisol, glutamate, and lactate—that correlate with clinical assessments and imaging results.
  • The findings show significant relationships between blood lactate levels and clinical/neuroimaging parameters, suggesting that changes in lactate and cortisol levels may reflect underlying immunological shifts and brain chemistry relevant to schizophrenia subtypes.

Introduction: The standard care of schizophrenia patients is based on the assessment of their psychotic behavior, using interview-based, subjective scales that measure symptoms severity. We aimed at defining easily accessible and inexpensive blood-derived clinical diagnostic parameters that might serve as objective markers in the prediction of the effects of pharmacological treatment of schizophrenia patients.

Methods: A total of 40 patients with schizophrenia diagnosis according to ICD 10 during psychotic decompensation were included in the study.

The altered cerebral energy metabolism central to schizophrenia can be linked to lactate accumulation. Lactic acid is produced by gastrointestinal bacteria, among others, and readily crosses the blood-brain barrier, leading to the brain acidity. This study aimed to examine the association of the oral microbiota with the effects of acid stress induced by an increase of brain lactate in schizophrenia patients.

Thyroid abnormalities, including mild forms of hypothyroidism and hyperthyroidism, are reported as risk factors for the development of a number of neuropsychiatric disorders, including schizophrenia. The diagnostic process still takes into account the extreme ranges of the accepted reference values for serum TSH since the concentration of free thyroxine in the serum does not change by definition. TSH mU/L cut-off values in psychiatric patients are currently clinically considered in the case of extremely high serum TSH levels (>4.

Despite extensive research, there is no convincing evidence of a reliable diagnostic biomarker for schizophrenia beyond clinical observation. Disorders of glutamatergic neurotransmission associated with N-methyl-D-aspartate (NMDA) receptor insufficiency, neuroinflammation, and redox dysregulation are the principal common mechanism linking changes in the periphery with the brain, ultimately contributing to the emergence of negative symptoms of schizophrenia that underlie differential diagnosis. The aim of the study was to evaluate the influence of these systems via peripheral and cerebral biochemical indices in relation to the patient's clinical condition.

Schizophrenia is a complex mental disorder whose course varies with periods of deterioration and symptomatic improvement without diagnosis and treatment specific for the disease. So far, it has not been possible to clearly define what kinds of functional and structural changes are responsible for the onset or recurrence of acute psychotic decompensation in the course of schizophrenia, and to what extent personality disorders may precede the appearance of the appropriate symptoms. The work combines magnetic resonance spectroscopy imaging with clinical evaluation and laboratory tests to determine the likely pathway of schizophrenia development by identifying peripheral cerebral biomarkers compared to personality disorders.
