Abstract
BACKGROUND: The aim of this study was to evaluate the monocyte chemoatractant protein-1 (MCP-1) as a novel biomarker of renal lesion in sickle cell disease (SCD) and correlate it with oxidative stress. METHODS: This is a prospective study with SCD patients followed at a tertiary center in Brazil. Urine samples were collected to dosage of protein, MCP-1, malondialdehyde (MDA) and urinary creatinine. Patients taking hydroxyurea (SSHU) were compared to those not taking the drug (SS). Patients' data were also compared to a control group of 15 healthy blood donors. RESULTS: MCP-1 dosage was increased in SCD patients (Control: 42.12±27.6; SSHU: 168.2±90.1 and SS: 231.4±123.7 p<0.0001). SS patients presented higher levels of MCP-1 in comparison to SSHU group (SSHU: 168.2±90.10 and SS: 231.4±123.7; p=0.023). The same results were observed for MDA (Control: 2:29±1:13; SSHU: 5.60±2.39 and SS: 7.23±2.64, p<0.0001) and NO (control: 2.25±1.9; SSHU: 56.54±9.1 and SS: 39.1±9.02, p<0.0001). A positive correlation was obtained between MCP-1 and MDA (r=0.34, p=0.01); albuminuria (r=0.5, p=0.03); NO (r=0.39, p=0.005). CONCLUSION: The outcomes of the study suggest that MCP-1 is a predictive biomarker of renal lesion that can also reflect damage caused by oxidative stress present in SCD.
