INTO-HLH (Insight into the Natural History and Treatment Outcomes of Hemophagocytic Lymphohistiocytosis) is a disease Registry aimed at advancing what is known about HLH. The insights obtained from this Registry will help doctors to better diagnose and manage HLH and improve treatment outcomes for future patients.

HLH Overview

Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome resulting in life-threatening organ damage.

In individuals with familial HLH, inherited genetic abnormalities damage a key 'off switch' in the immune system, such that it struggles to turn off, and cytokine storm develops

The causes of Hemophagocytic Lymphohistiocytosis (HLH) are not always clear, but most often, it occurs either due to inborn problems of immune regulation or as a complication of rheumatologic conditions or cancers. It may be triggered by infections in each of these contexts.

HLH is characterized by a unique set of clinical and laboratory features such as low blood counts, very elevated markers of inflammation, and an increase in the size of the spleen. This distinctive condition occurs in different clinical contexts, where it may appear and be treated somewhat differently.
