简要总结
This study aimed to investigate the efficacy and safety of Pegaspargase together with liposomal doxorubicin, etoposide and high dose methylprednisolone (L-DEP) as a salvage therapy for refractory Epstein Barr virus-induced hemophagocytic lymphohistiocytosis.

结局指标
主要结局
Evaluation of treatment response
时间窗: Change from before and 2,4,6 and 8 weeks after initiating L-DEP salvage therapy
A complete response was defined as normalization of all of the quantifiable symptoms and laboratory markers of HLH, including levels of sCD25, ferritin, and triglyceride; hemoglobin; neutrophil counts; platelet counts; and alanine aminotransferase (ALT). A partial response was defined as at least a 25% improvement in 2 or more quantifiable symptoms and laboratory markers as follows: sCD25 response was\>1.5-fold decreased; ferritin and triglyceride decreased at least 25%; for patients with an initial neutrophil count of\<0.5 ×109/L, a response was defined as an increase by at least 100% to\>0.5× 109/L; for patients with a neutrophil count of 0.5 to 2.0 × 109/L, an increase by at least 100% to \>2.0 × 109/L was considered a response; and for patients with ALT \>400 U/L, response was defined as an ALT decrease of at least 50%.
Change of Epstein-Barr virus(EBV)-DNA
时间窗: Change from before and 2, 4, 6 and 8 weeks after initiating L-DEP salvage therapy
次要结局
- Adverse events that are related to treatment(through study completion, an average of 2 years)
- Survival(from the time patients received L-DEP salvage therapy up to 24 months or November 2019)
