Official title

Hemophagocytosis in Critically Ill Adult Patients With Cytopenias

Overview

The purpose of the study is to find out whether non-responsiveness to therapeutic recombinant human granulocyte colony-stimulation factor (rhG-CSF) is associated with hemophagocytosis in critically ill adult patients with cytopenias.

Detailed description

In children with bi- or pancytopenia, hemophagocytosis is known as life-threatening hemophagocytic lymphohistiocytosis (HLH). The purpose of the study is to find out whether adult patients with bicytopenia or pancytopenia fulfilling the clinical HLH criteria used in children reflect life-threatening hemophagocytosis and whether hemophagocytosis is associated with responsiveness to recombinant human granulocyte colony-stimulation factor (rhG-CSF) or not.

Primary outcome measures

  • responsiveness to recombinant human granulocyte colony-stimulating factor (rhG-CSF) [Time frame: within 7 days]
Secondary outcome measures (1)
  • 8 clinical HLH criteria [Time frame: 7 days]
