ABSTRACT

Purpose:

HLH is a severe hyperinflammatory syndrome characterized by highly active cytotoxic T-cells, NK-cells, and macrophages. If undiagnosed, HLH can lead to multiorgan damage and death. Conditions triggering HLH are infections, malignancies and autoimmune/-inflammatory (MAS-HLH) disorders. Immunosuppressive patients are prone to develop infection triggered HLH. The incidence in the European community hospital is unknown, as is the number of unrecorded cases. HLH-patients, diagnosed at a single communal hospital with an adjacent catchment area of 500,000 citizens, were reviewed in the context of national and international guidelines.

Methods:

From 08/2016 to 11/2020, 13 HLH patients were analysed retrospectively. Both HLH-2004 criteria and the web-based Hscore were used to diagnose HLH. The collected data depicts clinical presentation, underlying disease, laboratory findings, and treatment.

Results:

This Study includes 13 HLH-patients (10 male). Median age at diagnosis was 53, ranging from 27-80 years. Most common triggers in our cohort were infections (n=7) and malignancies(n=4). MAS-HLH (n=1) was seen in a Still's disease patient. HLH-related gene mutation was identified (n=1) with a heterozygote mutation in Perforin (PrfA91). Lymphomas of B-as well as T-cell origin (n=2) and AML (n=3) represented main cause in malignancy associated HLH. Viral infections i.e., COVID-19(n=1), RSV (n=1) and EBV (n=1), also bacterial infections like M. tuberculosis (n=1), and the attenuated strain BCG (n=2) were seen in infection associated HLH. Most patients presented with fever (n=9) and splenomegaly (n=4). HLH patients show pancytopenia, peak ferritin levels ranging 1352-185000 ng/ml (median=21600), peak soluble IL-2 receptor levels ranging 2571-21660 U/ml (median=6606), and peak triglyceride levels ranging 175-610 mg/ml (median=227). Hemophagocytosis in bone marrow was found in 6 patients. First line therapy was glucocorticoids (n=12) combined with polyvalent immunoglobulins. Etoposide (n=5) and chemotherapy (n=4) were given to malignancy triggered HLH. Rituximab was applied in EBV-triggered HLH. Anakinra (n=3) and Ruxolitinib (n=4) was given to selected patients. Two patients received cytokine-depletion using adsorption columns Cytosorb®. Multiorgan failure (n=5) was the most common cause of death.

Conclusion:

This data provides incidence estimation of HLH in adult patients. Institutional and national measures will be presented to prevent death due to HLH.
