Background High uric acid levels are a risk factor for cardiovascular disorders, and metabolic diseases; however, the role of serum uric acid (sUA) during the mycoplasma pneumoniae pneumonia (MPP) of children is poorly known. This study aimed to clarify the effects of sUA during the MPP of children. Methods This was a prospective cohort study of children with MPP from multi‐center inpatient departments from September 2019 to August 2020. Routine laboratory characteristics analyzed including ALT, AST, BUN, CREA, UA, LDH, CK‐MB, WBC, N%, PLT, and CRP. Subjects were divided into 3 groups: non‐MPP, mild MPP (MMPP), and severe MPP (SMPP). Results 949 subjects were enrolled, including 207 in non‐MPP, 565 in MMPP, and 177 in SMPP. The optimal cutoff value for sUA is 239 μmmol/L in receiver operating characteristic (ROC) curves analysis. Multivariate logistic regression showed that WBC and sUA had significance for protective effects between non‐MPP and SMPP, but CRP did not have significance between the two groups, N and PLT had significance for risk factors; WBC and sUA did not have significance for the protective effects between non‐MPP and MMPP, CRP had significance between the two groups, N and PLT had significance for the risk effects. Similarly, binary logistic regression showed UA, WBC, and CRP had significance for the protective effects between non‐MPP and MPP, but N and PLT had significance for the risk effects between the two groups. Conclusion Both multivariate and binary logistic regression demonstrated that sUA displayed a protective effect during the MPP of children, which meant sUA is anti‐inflammatory. High uric acid levels are a risk factor for cardiovascular disorders,metabolic diseases; however, the present study displayed that serum uric acid (sUA) during the mycoplasma pneumoniae pneumonia (MPP) of children may have anti‐inflammatory effect.
