The concept of schizophrenia as a systemic disease includes, not only psychosis, but an increase in somatic comorbidity and cardiovascular risk [1]. Furthermore, it is known the implication of inflammation in the pathogenesis of schizophrenia [2].
To determinate potential inflammatory/metabolic biomarkers of schizophrenia's dimensions.
Sample: 36 outpatients with schizophrenia for less than 11 years, under stable maintenance treatment (mean age [32.25], males [63.9%]) and their 36 matched controls (age [32.53 ± 6.63]; males [72.2%]).
PANSS, Clinical Assessment Interview for Negative Symptoms(CAINS), Calgary Scale(CDS), CGI, Personal and Social Performance Scale(PSP). Biomarkers: C-reactive protein (CRP), homocysteine, glucose, insulin, HOMA-IR (insulin resistance), cholesterol, HDL, LDL, triglycerides.
Biomarkers differences between groups are shown in Table 1. Table 2 shows the correlations found after controlling for Body Mass Index [patients(28.61 ± 5.69);controls(24.64 ± 3.80);p = 0.001] and Smoking [patients(52.8%-yes);controls(5.6%-yes);p = 0.000].
1. CRP, a potential inflammatory biomarker in schizophrenia, is related to depression severity. Homocysteine, representing an oxidative stress, is related to positive, negative, cognitive and depressive symptoms severity, and worse functioning. 2. Patients with schizophrenia have lower HDL–related to negative and cognitive symptoms severity and worse functioning–and insulin resistance – related to worse cognition –.
