The analysis about the level of inflammatory factors in transfusion-ralated neonatal necrotizing ;enterocolitis / 中国医师进修杂志

Objective To observe the change of serum inflammatory factors such as tumor necrosis factor (TNF)-α, interleukin (IL)-6 before and after blood transfusion, and analyze the possible pathogenesis of transfusion-associated neonatal necrotizing enterocolitis (NEC). Methods One hundred and sixty-two patients who needed blood transfusion in NICU from Janury 2014 to Octorber 2015 were enrolled in this study. Among them, 13 patients had transfusion-ralated neonatal necrotizing enterocolitis (TRNEC, test group A), and 149 patients didn′t have TRNEC (test group B). In the mean time, 45 NEC patients without blood transfusion in 1 292 patients was as control group A, 30 patients who didn′t receive blood treatment and had NEC was as control group B. The levels of TNF-α, IL-6 in four groups were compared. Results The rate of TRNEC was 8.02% (13/162). The rate of NEC was 3.48%(45/1 292), and there was significant difference (χ2=7.79, P<0.01). The levels of serum TNF-α, IL-6 at 24 h and 48 h after blood transfusions in test group A and test group B were increased compared with those in control group B (P<0.01 or<0.05). The levels of serum TNF-α, IL-6 at 24 h and 48 h after blood transfusions in test group A were increased compared with those in test group B and control group A (P<0.01 or<0.05). The levels of serum TNF-α, IL-6 at 24 h and 48 h after blood transfusions in test group B were decreased compared with those in test group A (P<0.05). The levels of serum TNF-α, IL-6 at 24 h and 48 h after NEC in control group A were increased compared with those in control group B (P<0.05). Conclusions The pathogenesis of TRNEC may have connection with the inflammatory factors such as TNF-α, IL-6, which are produced in the processing of handling whole blood and the storage of red cell.
