Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy

    Accuracy (expressed as specificity/sensitivity/NPV/PPV) will be assessed as compared to the revised EORTC-MSG criteria, at moment of diagnosis by high-resolution CT and bronchoscopy

    Through study completion (i.e. 6 weeks after diagnosis)

Secondary Outcomes (2)

  • Diagnostic accuracy at 2 weeks as compared to the revised EORTC-MSG response criteria using high-resolution CT

    2 weeks after diagnosis

  • Diagnostic accuracy at 2 weeks as compared to the revised EORTC-MSG response criteria using high-resolution CT

    6 weeks after diagnosis

Sampling MethodProbability Sample
Study Population

Patients at high risk for opportunistic respiratory infections due to acute myeloid or lymphatic leukemia (undergoing intensive treatment), patients who underwent allogeneic stem cell transplantation, and patients receiving autologous stem cell transplantation

You may qualify if:

  • Age ≥ 18y at start of study
  • One of the following diagnoses:
  • De novo, refractory or relapsed AML/MDS receiving intensive chemotherapy
  • De novo, refractory or relapsed ALL/T-lymphoblastic lymphoma receiving intensive chemotherapy
  • Aplastic anemia requiring ATG therapy
  • Any patient admitted for either autologous hematopoietic stem cell transplantation. Transplantation may not have been performed at time of enrolment.
  • Any patient admitted with allogeneic hematopoietic stem cell transplantation within the last year, or planned during this admission.
  • Written informed consent obtained from the patient

You may not qualify if:

  • Signs of active respiratory infection
  • If previously enrolled: incomplete clearance of all signs of respiratory infection (both clinically, microbiologically and radiologically).
