Abstract:
Objective:To analyze the value of C-reactive protein to prealbumin ratio (CRP/PA) combined with neutrophil CD64 (nCD64) index in evaluating the severity and prognosis of mycoplasma pneumonia (MPP) in children.Methods:The clinical data of 98 children with MPP admitted to Changzhou Maternal and Child Health Hospital from March to December 2023 were retrospectively analyzed. According to the severity of the patients, they were divided into mild children (60 cases) and severe children (38 cases). After 7 days of routine treatment, the patients were divided into good prognosis group (72 cases) and poor prognosis group (26 cases). The CRP/PA and nCD64 indices of children with different severity of disease were compared, and the relationship between CRP/PA and severity of disease was analyzed. The clinical data of children with different prognosis outcomes were compared, and the influencing factors of prognosis were analyzed. The area under receiver operating characteristic (ROC) curve (AUC) was used to analyze the prognostic value of CRP/PA and nCD64 index.Results:CRP/PA[(1.05±0.21) vs (0.77±0.15)] and nCD64 index [(4.11±0.82) vs (2.96±0.59)] in severe children were higher than those in mild children (all P<0.05). Pearson analysis showed that CRP/PA and nCD64 index were positively correlated with clinical pulmonary infection score (CPIS) ( r=0.587, 0.574, all P<0.05). Univariate analysis showed that the age of the poor prognosis group [(4.81±0.96)years vs (6.67±1.33)years] was smaller than that of the good prognosis group. The severity of the disease was severe [65.38%(17/26) vs 29.17%(21/72)], complicated complications [46.15%(12/26) vs 18.06%(13/72)], CRP/PA[(1.23±0.25) vs (0.74±0.15)] and nCD64 index [(4.48±0.89) vs (3.02±0.61)] were higher than those in good prognosis group (all P<0.05). Binary logistic regression analysis showed that the severity of disease ( OR=4.251, 95% CI: 1.682-10.742), CRP/PA ( OR=3.857, 95% CI: 1.886-7.887), nCD64 index ( OR=3.161, 95% CI: 1.382-7.228) were prognostic factors (all P<0.05). ROC curve showed that the sensitivity and specificity of CRP/PA, nCD64 index and their combination in predicting prognosis were 76.90%, 73.10% and 88.50%, respectively, and 73.60%, 72.20% and 90.30%, respectively. The AUC values were 0.809, 0.794 and 0.923 (all P<0.001). Conclusions:CRP/PA and nCD64 index are significantly positively correlated with the severity of MPP in children, and they are the influencing factors for the prognosis of children. The combined detection of CRP/PA and nCD64 index has good predictive value for the prognosis of children.
