Abstract

Hyperbilirubinemia is one of the most crucial syndromes, which is characterized by high levels of bilirubin, especially when it occurs in newborns. Bilirubin has cytoprotective properties with an antioxidant function and plays several major roles in the inflammation process with its members such as chemokines. The monocyte chemoattractant protein-1 (MCP-1) is a member of the C-C chemokine family and it has been associated with the inflammatory process. There are no data on the chemokine and its receptor genotypes in hyperbilirubinemic newborns to show their distribution. The aim of this study is to investigate the genotypic relationship of MCP-1 and its receptor CCR2-V64Ι with hyperbilirubinemia in Turkish newborns. A total of 85 newborns were included in the study: 20 infants with hyperbilirubinemia (hyperbilirubinemic group) and 65 infants without hyperbilirubinemia (non-hyperbilirubinemic group). Genotyping of MCP-1 A-2518G and CCR2-V64Ι gene polymorphisms were detected by PCR-RFLP, respectively. MCP-1 GG genotype in patients was higher than the controls and this genotype had 2.69 times higher risk for hyperbilirubinemic neonates (P: 0.20). The frequency of MCP-1 A-2518G G+ genotype in patients was higher than the controls (55.0% and 38.5%, respectively). The results of our preliminary study suggest that MCP-1 G+ genotype has the ability to increase the hyperbilirubinemia risk of newborns. These results should be focused on to research on a larger scale to confirm the findings.
