Clinical Trial Summary

Hemophagocytic lymphohistiocytosis (HLH) associated with hematologic malignancies (HM-HLH) is a syndrome with an abysmal prognosis (10-30% 5 years overall survival). We have recently established an improved diagnostic and prognostic index for HM-HLH, termed the Optimized HLH Inflammatory (OHI) index. The OHI index is comprised of the combined elevation of soluble CD25 (sCD25) > 3,900 U/mL and ferritin >1,000 ng/mL . However, the true incidence and outcomes of HLH/OHI+ in an unselected cohort are unknown and so is the mechanism of HM-HLH.

Description:

The investigators will enroll patients with new/transformed hematologic malignancies. We will follow the patients until the end of the study, report their survival at one year and examine their prognosis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To assess 365 days mortality of OHI+ and OHI- patients	We will use Kaplan-Meier curves to compare survival between OHI+ and OHI- patients	Mortality rate one year from OHI assessment
Secondary	To determine the incidence of OHI+ patients in our cohort	We will assess the incidence of OHI+ within our cohort (OHI+/total patients enrolled)	We will assess the incidence after three years of enrollment
