The importance of blood count and oxidative stress in the drug-naïve first episode schizophrenia

Introduction Schizophrenia (SZ) is associated with changes in haematological parameters related to low-grade inflammation state and could be amplified via oxidative stress (OS) related mechanisms. Although studies confirm this relationship, the results could be cofounded by patients’ treatment. Ob...

description Introduction Schizophrenia (SZ) is associated with changes in haematological parameters related to low-grade inflammation state and could be amplified via oxidative stress (OS) related mechanisms. Although studies confirm this relationship, the results could be cofounded by patients’ treatment. Objectives The study aimed to assess the connection between venous blood count and OS in drug-naïve first-episode SZ patients. Methods The study consisted of 24 SZ drug-naïve patients during first episode of psychosis (median age: 22 years), and 31 healthy individuals (HC) as a control group (median age: 28 years). The examination included clinical data, OS parameters (enzymatic and non-enzymatic antioxidants), peripheral blood counts. Results We did not find differences between SZ and HC in blood count parameters (p>0.05). In patients group, white blood cells (WBC), neutrophils and neutrophils-to-lymphocyte ratio (NLR) were positively related with the severity of positive symptoms (R=0.59, R=0.53, R=0.50; p<0.05, respectively). WBC was related to superoxide dismutase (SOD-1) levels (HC: R=-0.36, SZ: R=0.70; p<0.05). Neutrophils were positively related to catalase (CAT) (R=0.52; p<0.05) and ferric reducing antioxidant power (FRAP) (R=0.61; p<0.05), but only in the patients’ group. There was a positive relationship between NLR and CAT (R=0.45; p<0.05) in the SZ group. Conclusions The results indicate potential connection and interplay between OS and blood count parameters in the onset of psychotic episode. Further studies on a larger group of patients are needed. Disclosure No significant relationships.
