What the trial is, and whether it could suit you
Adult secondary HLH involves tumors, autoimmune diseases and other causes in addition to infection,Infectious factors, theoretically need different treatment methods for different etiology. But adult HLH itself disease .The situation progresses ferociously, which can cause organ damage and blood coagulation disorder and endanger life quickly, with early mortality (30days).It can be more than 50%. On the other hand, although diagnostic techniques have improved significantly, identifying the cause is still costly Time, such as 1-2 weeks for the pathological diagnosis of lymphoma, leads to more patients losing further treatment due to early death.
The opportunity to heal. Therefore, it is important to explore effective induction therapy for adult HLH. In the majority ,Early (30-day) mortality was as high as 40% after cardiac induction using HLH2004 or CHOP(cyclophosphamide, hydroxydaunomyc
