OBJECTIVE: To investigate the expression and clinical significance of soluble B7-H3 (sB7-H3) in patients with secondary hemophagocytic lymphohistiocytosis (sHLH).
METHODS: The plasma samples of 85 newly diagnosed sHLH patients from December 2012 to April 2018 were collected. The patients were divided into lymphoma-related HLH（LHLH）group and infection-related HLH（IHLH）group. The expression of sB7-H3 in plasma was detected by ELISA, and the clinical data were collected for analysis. Fifteen healthy people were chosen as control group.
RESULTS: The expression level of sB7-H3 in lymphoma-related HLH and infection-related HLH group significant increased as compared with the control group, (P＜0.05), and the expression level of sB7-H3 in lymphoma-related HLH group was significant higher than that in infection-related HLH group [(35.75± 9.90) vs (28.70±8.95) ng/ml)] (P＜0.001). There were no significant statistical difference in the expression of some clinical factors (including age, fever, splenomegaly, ANC, Plt, FIB, calcium ion, serum albumin, LDH, serum ferritin, sCD25) in lymphoma-related HLH and infection-related HLH group (P＞0.05). The evaluation of expression and significance of sB7-H3 in sHLH by using ROC curve, showed that the area under ROC curve comparison of patients in lymphoma-related HLH group and infection-related HLH group was 0.718 (95% CI 0.610-0.810) (P=0.0002), and predicting the sensitivity and specificity of the lymphoma-related HLH patients were 77.36% and 59.38%, respectively. The best cut-off value of patients in sB7-H3 was 29.81 ng/ml, the overall survival time of sB7-H3 high-expression group (≥29.81 ng/ml) was significant shorter than that in low-expression group (＜29.81 ng/ml) (24 vs 440 d) (P＜0.001). The clinical factors affecting the survival status of sHLH patients were neutrophils, albumin, serum ferritin, serum calcium ions and sB7-H3 levels.
CONCLUSION: sB7-H3 associates with poor prognosis of sHLH patients, and may be involved in disease progression.
