Abstract:
Objective:To study the changes of plasma receptor interacting protein 3 (RIP3) levels in neonatal late-onset sepsis (LOS) and to determine its clinical value.Methods:From October 2019 to April 2021, plasma samples and clinical data of LOS infants admitted to our hospital were prospectively studied. Infants with similar gestational ages admitted for non-infectious diseases were assigned into the control group. Enzyme-linked immunoassay was used to determine plasma RIP3 levels. The clinical value of plasma RIP3 in the diagnosis and treatment of neonatal LOS were analyzed.Results:A total of 152 cases (76 in the LOS group and 76 in the control group) were included in the study. No significant differences existed in the baseline data between the two groups. A total of 226 plasma samples were collected (76 samples from the LOS group before treatment, 74 samples after treatment and 76 samples from the control group). The plasma RIP3 level of LOS group before treatment (19.9±6.3 ng/ml) was significantly higher than the control group (11.4±3.5 ng/ml) and the after treatment group (11.9±3.5 ng/ml) ( P<0.05). The plasma RIP3 level had good diagnostic value for neonatal LOS (AUC=0.884). With cut-off value of 15.5 ng/ml, the plasma RIP3 showed the best diagnostic efficacy (Youden index 0.658, sensitivity 72.4%, specificity 93.4%, positive likelihood ratio 11.0, negative likelihood ratio 0.3). Conclusions:Plasma RIP3 level is closely related with neonatal LOS and may be used for the early diagnosis and therapeutic evaluation of neonatal LOS.
