Abstract:
OBJECTIVE:To investigate the clinical value of expression level of interleukin-2 receptor (IL-2R) and interleukin-8 (IL-8) in the fever patients with hematological malignancies.
METHODS:A total of 121 inpatients in the First Affiliated Hospital of Anhui Medical University from April 2018 to October 2019 were enrolled in this study. The patients were separated into infection group (61 cases) and non-infection group (60 cases). In the meantime, 40 healthy people without fever or infection in the hospital for physical examination were set as matched group. C-reactive protein (CRP), procalcitonin (PCT), and cytokines were detected in all the patients with fever after admission and infection control. While, blood samples were taken from healthy people during physical examination.
RESULTS:The expression levels of IL-2R in infection group were higher than those in the control group (P<0.001), and the level of serum IL-2R in infection group was also higher than that in the non-infection group (P<0.05). Based on Spearman analysis, in patients with malignant hematologic disease, serum IL-2R level was positively correlated with CRP (r=0.557, P<0.001) and IL-8 (r=0.479, P<0.001), and IL-8 level was positively correlated with CRP (r=0.318, P<0.001). Compared with the non-infection group, the area under the curve (AUC) for the level of CRP, PCT, and IL-2R of the infection group was 0.714 (95%CI: 0.623-0.806), 0.765 (95%CI: 0.680-0.851), and 0.761 (95%CI: 0.686-0.836), the sensitivity was 0.705, 0.852, and 0.705, and the specificity was 0.717, 0.70, and 0.60, respectively. While, AUC of CRP+PCT, CRP+IL-2R, PCT+IL-2R, and CRP+PCT+IL-2R was 0.789 (95%CI: 0.712-0.866), 0.702 (95%CI: 0.623-0.782), 0.757 (95%CI: 0.677-0.838), and 0.789 (95%CI: 0.712-0.866), the sensitivity was 0.738, 0.934, 0.705, and 0.738, and the specificity was 0.840, 0.470, 0.810, and 0.840, respectively.
CONCLUSION:CRP, PCT, IL-2R, and IL-8 are useful parameters for diagnosis of the infectious fever in patients with hematological malignancies, which provides the basis of initial diagnosis and rational use of antibioties for clinician.
