ABSTRACT
OBJECTIVE:
To explore Cytomegalovirus (CMV) antigen-specific multi-cytokine immune responses in patients with rheumatic disease (RD) under different CMV infection status.METHODS:
A total of 60 RD patients in our center from March 2023 to August 2023 were enrolled. The patients were divided into latent CMV infection and active CMV infection, the latter was classified as subclinical CMV infection or CMV disease based on presence or absence of symptoms related to CMV. Whole blood was collected and stimulated with QuantiFERON-CMV antigen. The levels of IFN-γ, TNF-α, IL-2, IL-4, IL-6, IL-10, IL-17 and CXCL-2 in supernatant were measured by Luminex Assays. The receiver operating characteristic curve was used to evaluate the diagnostic accuracy of cytokine for distinguishing different CMV infection status.RESULTS:
The proportion of patients with severe lymphopenia was lowest in the latent CMV infection group, while there were no significant differences in medication usage in different CMV infection status. After stimulation with QF-CMV antigens, the levels of IFN-γ, TNF-α and IL-2 in the CMV disease group were significantly lower than those in the latent CMV infection group. CMV antigen-specific IFN-γ, TNF-α levels and severe lymphopenia together provided the best discriminatory performance for distinguishing between latent and either active CMV infection patients (AUC = 0.854) or CMV disease patients (AUC = 0.935).CONCLUSION:
Noninvasive peripheral blood biomarkers (the combination of CMV antigen-specific IFN-γ, TNF-α levels and severe lymphopenia) may have the potential to diferentiate different status of CMV infection in RD population.Palavras-chave
