Abstract:
ObjectiveNecrotizing fasciitis (NF) has a high rate of deterioration and rapid progress, and the mortality rate is still high even after receiving treatment. The study was to explore evaluation value of serum procalcitonin (PCT), C-reactive protein (CRP) and plasma albumin (ALB) and prealbumin (PA) in the prognosis of patients with perianal necrotizing fasciitis (NF).MethodsAll data and detection data of serum PCT, CRP and plasma ALB, PA at admission from 41 perianal NF patients admitted to Hefei first people's Hospital Group from May 2009 to August 2019 were retrospectively collected. The death status was statistically analyzed. The patients in this group were divided into survival group and non-survival group, and the predictive value of various indicators on the prognosis of NF was evaluated. ResultsThe ratio of male to female was 9.25∶1. There were multiple complications, and diabetes mellitus was most common (41.46%). The patients with mixed infection and negative bacterial culture accounted for 12.20% and 17.07%, respectively. There were many kinds of bacteria detected out. Klebsiella pneumoniae (20.45%), Escherichia coli (15.91%) and streptococcus (15.91%) were common. All underwent one or more surgical treatments, with mortality of 17.07%. There was no significant difference between survival group and death group in gender, complications, microbiological test results, operation status within 6h or and nutrition support (P>0.05), while there were significant differences in time from onset to admission, proportion of patients in ICU, serum PCT and CRP, plasma ALB and PA and proportion of patients undergoing vacuum sealing drainage (VSD) (P<0.05). Logistic multivariate regression analysis showed that long duration from onset to admission, staying in ICU, high serum PCT and CRP, low plasma ALB and PA, and no conducting VSD were risk factors of poor prognosis (P<0.05). Serum PCT, CRP and plasma ALB, PA predict the prognosis receiver operating characteristic(ROC) curve, the area under the curve is 0.859, 0.811, 0.802, 0.747; the area under the curve of the four indicators combined prediction is 0.926.ConclusionThere are certain features in terms of gender, complications and microorganisms in perianal NF patients. Death risk is high. In addition, serum PCT and CRP, plasma ALB and PA are also related with prognosis, which can be applied as biochemical indexes for prognosis evaluation.
