About

Purpose: C-reactive protein to albumin ratio (CAR) has emerged as a novel marker of inflammation. However, almost no research has evaluated the role of CAR in septic arthritis (SA). There is currently controversy over the timing of surgery. Our aim is to explore the application of the CAR in predicting the treatment choice for SA in children under 4 years of age.

Methods: Retrospective analysis of the clinical data from children under four years of age admitted to the Department of Orthopedics at Children's Hospital of Soochow University between January 2016 and December 2022 due to SA. Patients were divided into surgery group and conservative group based on whether the patients underwent surgery. The clinical data of the two groups were compared. Multivariate logistic regression analysis was performed to determine the independent predictors for SA requiring surgical intervention. Receiver operating characteristic (ROC) curves were plotted for the independent predictive indicators, and the area under curve (AUC) was determined. The cut-off value was determined using Youden index, and diagnostic accuracy indicators such as sensitivity (SEN), specificity (SPE), positive predictive value (PPV) and negative predictive value (NPV) were calculated.

Enrollment: 82 patients

Sex: All

Ages: 1 day to 4 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• (1) Meeting the aforementioned SA diagnostic criteria, regardless of the affected joint; (2) Completing routine blood and biochemical tests within 24 hours of admission; (3) No surgery or antibiotics administered prior to admission.

Exclusion criteria

• (1) Cases of transient synovitis, rheumatism-related diseases (JIA, etc.), simple acute hematogenous osteomyelitis, or acute exacerbation of chronic hematogenous osteomyelitis after revision of the diagnosis; (2) Postoperative iatrogenic infection; (3) Incomplete clinical data.
