ABSTRACT

OBJECTIVE: To develop a method for determining cinnabarinic acid (CA) and its immediate precursor 3-hydroxyanthranylic acid (3HAA) in blood plasma and to study their concentrations in patients with schizophrenia before and after treatment. MATERIAL AND METHODS: The study was carried out on a sample of 23 female patients with an attack-like progredient schizophrenia (F20.01). The levels of CA and 3HAA in blood plasma were measured using liquid chromatography with tandem mass spectrometry. RESULTS: We found an inverse statistically significant correlation of the sum of CA and 3HAA concentrations before treatment with the total PANSS score after treatment (R=-0.50; p<0.05). There was also an inverse correlation of the CA concentration of before treatment with the total PANSS score after treatment (R=-0.41, p=0.052), statistically significant at the trend level (0.05

ABSTRACT

The importance of finding predictors or biomarkers of neuropsychiatric pathology, as well as methods of its prevention, treatment and early diagnosis is beyond question. The level of neopterin in body fluids is one of the possible biomarkers. Increased levels of neopterin in biological fluids (e.g., serum, cerebrospinal fluid or urine) are closely associated with various diseases associated with cellular immune response. The data presented in the review indicate the relevance of the study of neopterin concentrations in body fluids in patients with mental illness for the development of diagnostic and prognostic tests or as a pharmacodynamic marker of drug action.
