Abstract:
Objective
To analyze the risk factors of multidrug-resistant bacterial (MDRO) infection in neonatal intensive care unit (NICU) and the diagnostic value of hypersensitive C-reactive protein to albumin ratio (hs-CRP/ALB).
Methods
Total of 105 neonates with MDRO infection in NICU of The Maternity and Child Care Hospital of Kunshan from October 2020 to October 2023 were collected as MDRO group, 150 neonates without MDRO infection as non-MDRO group, and 150 healthy newborns as healthy group during the same period.The risk factors for MDRO infection were analyzed by Logistic regression analysis.The diagnostic value of hs-CRP/ALB for neonatal MDRO infection were evaluated by receiver operating curve (ROC) analysis.
Results
Birth weight (OR = 2.065, 95%CI: 1.184-3.600, P = 0.011), Apgar score (OR = 2.470, 95%CI: 1.294-4.717, P = 0.006), duration of antibiotic use (OR = 2.576, 95%CI: 1.287-5.155, P = 0.008), and deep venous catheterization (OR = 2.751, 95%CI: 1.268-5.971, P = 0.010) were all independent risk factors for neonatal MDRO.Compared with the healthy group, hs-CRP, ALB, white blood cell (WBC) count, neutrophil-to-lymphocyte ratio (NLR), absolute neutrophil count (NEUT#) and hs-CRP/ALB in the MDRO group were significantly higher on the first and the third day after admission (all P < 0.05).Compared with non-MDRO group, there was no significant difference for hs-CRP, ALB, WBC, NLR, NEUT#and hs-CRP/ALB on the first day after admission in MDRO group (all P > 0.05), but on the third day after admission, hs-CRP, ALB, NLR and hs-CRP/ALB were statistically significant (all P < 0.05).On the third day,the sensitivity and specificity of hs-CRP/ALB for the diagnosis of neonates in MDRO group and non-MDRO group were 63.09% and 86.67%, respectively.Compared with the survival group, the death group showed significant differences in hs-CRP, ALB and hs-CRP/ALB on the third and the fifth day after admission (all P < 0.05), NLR was significantly different on the fifth day after admission (Z = 3.878, P < 0.001); NEUT#was significantly different on the third day after admission (Z = 2.533, P = 0.013); However, there was no significant difference of WBC on the third and the fifth day after admission (all P > 0.05).Hs-CRP/ALB of all neonates infected with methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistat Enterococcus(VRE) and multidrug/pan-drug-resistant Pseudomonas aeruginosa (MDR/PDR-PA) were all higher than 0.36.Among the Methicillin-resistant coagulase-negative Staphylococci (MRCNS), extended-spectrum β-lactamase(ESBLs)-producing Enterobacteriaceae, carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemresistant Acinetobacter baumannii (CR-AB) infection-resistant neonates, hs-CRP/ALB > 0.36 accounted for 83.33%, 86.67%, 80.00% and 80.00%, respectively.
Conclusions
The detection of hs-CRP/ALB ratio can be used to preliminarily determine the severity of neonatal infection and corresponding preventive measures should be taken for the risk factors of neonatal MDRO infection.
