FABP2 and schizophrenia: In this context, the objectives of the study were (a) to measure intestinal permeability in a cohort of patients with schizophrenia through plasma markers related to bacterial translocation – LBP, LPS, and I-FABP; (b) to investigate its association with the clinical severity of schizophrenia across the main symptomatic domains including positive symptoms, negative symptoms, and cognitive performance; and (c) to analyze the impact of lifestyle habits on these biomarkers.
