Association of Peripheral Markers of Oxidative Stress with Clinical Parameters and Inflammatory Factors in Alcoholic Patients.

One of the fundamental problems in studying addiction is elucidation of mechanisms of alcohol dependence (AD) development. Disturbances of cellular redox balance and inflammation play an important role in AD pathogenesis. Deciphering associations between biological and clinical indicators can elucidate molecular mechanisms of disease pathogenesis.

Serum Levels of S100B Protein and Myelin Basic Protein as a Potential Biomarkers of Recurrent Depressive Disorders.

Nowadays, nervous tissue damage proteins in serum are considered promising drug targets and biomarkers of Mood Disorders. In a cross-sectional naturalistic study, the S100B, MBP and GFAP levels in the blood serum were compared between two diagnostic groups (patients with Depressive Episode (DE, n = 28) and patients with Recurrent Depressive Disorder (RDD, n = 21)), and healthy controls (n = 25). The diagnostic value of serum markers was assessed by ROC analysis.

Different Directions of Effects of Polyclonal IgG Antibodies from Patients with Schizophrenia and Healthy Individuals on Cell Death In Vitro: A Pilot Study.

Numerous studies indicate the involvemen of oxidative stress in the pathogenesis of schizophrenia. It has been shown that the serum pool of antibodies in patients with schizophrenia contains catalytically active antibodies (abzymes) that have a wide range of activities, including redox properties. In the present work, the effects of IgGs-having oxidoreductase activities-isolated from the serum of patients with schizophrenia and healthy individuals were studied in vitro.

Immunoglobulins G of Patients with Schizophrenia Protects from Superoxide: Pilot Results.

This study aimed to evaluate the superoxide dismutase (SOD) activity of IgG in patients with schizophrenia. After signing informed consent, we included 67 patients with schizophrenia (34 people with acute schizophrenia and 33 individuals were on outpatient treatment in therapeutic remission) and 14 healthy volunteers. IgGs from blood serum were isolated by affinity chromatography.

Beta-Endorphin and Oxytocin in Patients with Alcohol Use Disorder and Comorbid Depression.

Background: The neuropeptides β-endorphin and oxytocin are released into the bloodstream as hormones from the pituitary gland but also have an important function as neuroregulators in the forebrain. The blood levels of both polypeptides have been shown to reflect depressive symptoms. β-Endorphin, in particular, is also involved in abstinence from alcohol.

Exploring Brain Derived Neurotrophic Factor and Cell Adhesion Molecules as Biomarkers for the Transdiagnostic Symptom Anhedonia in Alcohol Use Disorder and Comorbid Depression.

Background: Alcohol Use Disorder (AUD) and depressive disorder often co-exist and have a shared heritability. This study aimed to investigate Brain-Derived Neurotrophic Factor (BDNF) and three Cell Adhesion Molecules (CAMs) as transdiagnostic biomarkers in AUD and depression co-morbidity.

Methods: In a cross-sectional study, patients with AUD (n=22), AUD and depression (n=19), and healthy controls (n=20) were examined.
