Necrotizing enterocolitis (NEC) is a major cause of the morbidity and high mortality in preterm infants. With the ELISA method there were determined cytokine concentrations of the transforming growth factor-β (TGF-β), macrophage inflammatory protein1β (MIP-1β), matrix metalloproteinases (MMP-2, -3, -8, -9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in low birthweight (LBW) premature infants with NEC. There were examined 68 infants at the conservative and surgical stages of NEC. In all patients on admission at 3rd and 7th day of the treatment the concentration of these compounds was determined in blood serum and tissues from damaged ileum and colon. There were established divergent differences in TGF-β content (reduction by 1,9-3 times) and MIP-1β (1.3-1.5 fold increase) in serum as compared with the control. More pronounced changes in the blood concentrations of these biomarkers in patients at the surgical stage of the NEC due to a decrease in TGF-β content, a significant increase in MIP-1β concentrations, MMP-8, TIMP-1 and the lack of the decrease in their content in the course of treatment, are associated with the severe course of NEC in LBW premature infants and prove to be indices of the unfavorable course of NEC, which requires to revise and optimize the therapeutic approach timely in such patients.
