The aim was to compare peripheral inflammatory markers between schizophrenia and acute and transient psychotic disorder and to evaluate age, sex, and smoking as predictors of biomarker variability. A total of 187 inpatients were examined in this retrospective cohort (schizophrenia n = 105; acute/transient psychosis n = 82). Leukocyte subtypes, platelets, C-reactive protein, erythrocyte sedimentation rate, and fibrinogen were assessed, and the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and systemic immune-inflammation index (SII) were calculated; parametric tests or the Mann–Whitney U test and multiple regression were used. At admission, mean (standard deviation) values for acute psychosis versus schizophrenia were as follows: NLR 2.19 (1.04) versus 1.79 (1.16), p = 0.004; PLR 135.94 (40.81) versus 120.42 (80.51), p<0.001; MLR 0.33 (0.16) versus 0.31 (0.33), p = 0.03; SII 587.12 (373.16) versus 452.14 (312.89), p = 0.004. Fibrinogen, however, was higher in schizophrenia: 298.75 (51.17) versus 269.29 (83.63), p = 0.02. Relative mean differences were reported as 22.3% for NLR, 12.9% for PLR, 6.5% for MLR, and 29.9% for SII, with higher values in acute psychosis, and 9.9% for fibrinogen, with higher values in schizophrenia. Patients with acute psychosis were younger; sex was associated with PLR and fibrinogen, while smoking was associated with erythrocyte sedimentation rate, NLR, and PLR. The authors concluded that the findings support marker-specific inflammatory profiles at different clinical stages of psychotic disorders.
