ABSTRACT: To develop a biological diagnostic model of vaso-occlusive crises based on oxidative, inflammatory, and metabolic biomarkers in Congolese sickle cell patients, a cross-sectional analytical study was conducted among 150 participants divided into four groups: HbAA controls (n = 30), HbAS subjects (n = 30), HbSS steady-state patients (n = 45), and HbSS patients during VOC (n = 45). Serum levels of FoxO3, interleukin-6 (IL-6), C-reactive protein (CRP), lactate, and malondialdehyde (MDA) were measured using ELISA, immunofluorescence, and enzymatic methods. Correlation analyses, linear regression, multivariate logistic regression, and ROC curve analyses were performed. FoxO3, IL-6, CRP, lactate, and MDA concentrations were significantly higher in HbSS patients during VOC compared with all other groups (p 2 = 0.66, p 2 = 0.55, p
