Trial summary

Pulmonary infiltrates frequently complicate the care of hematopoietic stem cell transplant (HSCT) and leukemia patients. Bronchoalveolar lavage (BAL) is frequently used to evaluate new pulmonary infiltrates in this population, however utility is limited by a historically low diagnostic yield for infection.

About this study

Official title: A Prospective Assessment of the Diagnostic Utility of Emerging Laboratory Assessments Used in Conjunction With FOB in HSCT and Leukemia Patients With Acute Respiratory Symptoms and Pulmonary Infiltrates

Pulmonary infiltrates frequently complicate the care of hematopoietic stem cell transplant (HSCT) and leukemia patients. Bronchoalveolar lavage (BAL) is frequently used to evaluate new pulmonary infiltrates in this population, however utility is limited by a historically low diagnostic yield for infection.

In an effort to improve diagnostic yields, this study will complete a Fiberoptic Bronchoscopy (FOB) within 8 hours of radiographic documentation of pulmonary infiltrates, prior to initiating new antibiotic therapy. To further improve detection of microbiological pathogens, the study will utilize PCR testing with rapid turnaround time to detect atypical pneumonia (M pneumoniae, C. Pneumonia, Legionella species, and respiratory viruses) and aspergillosis.

Read the detailed description

Proper diagnosis and prompt treatment favorably impacts survival in the post transplant setting, but is often difficult and frequently results in inappropriate or late therapy. Low yields may be linked with empiric antibody therapy begun prior to the procedure, delayed time to procedure, procedure technique, the presence of graft versus host disease (GVHD), neutropenia, and diffuse infiltrates (as opposed to localized infiltrates or focal masses and nodules). One recent study found that early FOBs (less than or equal to 4 days between detection of pulmonary infiltrates and FOB) were 2.5 times more likely to establish a diagnosis of pneumonia compared to late examinations. Delaying this procedure(greater than 5 days between detection of pulmonary infiltrates and FOB) was associated with drug resistant organisms, polymicrobial infections, and worsened patient prognosis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Positive Culture or Molecular Results After Brochoscopy

    To determine the diagnostic yield related to fiberoptic bronchoscopy (FOB) with bronchoalveolar lavage (BAL) in hematopoietic stem cell transplant (HSCT) and leukemia patients with acute respiratory symptoms and pulmonary infiltrates utilizing both current standard of care microbiology testing and emerging molecular genetic laboratory assessments.

    Measured: 30 days

Secondary outcomes (5)
  1. Number of Patients With Positive CT Result

    To correlate specific types of pulmonary infiltrates (focal, multifocal, or diffuse interstitial or alveolar infiltrates) with microbiological findings. Patients were evaluated by changes on the CT and categorized as follows:

    1. Air space
    2. ground glass/reticular nodular
    3. nodular/cavitary
    4. single patchy infiltrate

    Measured: 30 days

  2. Number of Participants With Positive Bacterial Results by PCR

    To describe the microbiological findings in HSCT and leukemia patients with fever, respiratory symptoms, and pulmonary infiltrates

    Measured: 24-48 hours

  3. Number of Patients With Positive Fungal Results by PCR

    To describe the microbiological findings in HSCT and leukemia patients with fever, respiratory symptoms, and pulmonary infiltrates

    Measured: 24-48 hours

  4. Number of Participants With Positive Viral Results by PCR

    To describe the microbiological findings in HSCT and leukemia patients with fever, respiratory symptoms, and pulmonary infiltrates

    Measured: 24-48 hours

  5. Number of Participants With Positive Myocbacteria Results by Culture

    To describe the microbiological findings in HSCT and leukemia patients with fever, respiratory symptoms, and pulmonary infiltrates

    Measured: 24-48 hours

Questions about this trial

What is this clinical trial studying?

A study testing Microbiological analysis in people with Pulmonary Infiltrate New, run by Northside Hospital, Inc. at 1 site in United States.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients With Positive Culture or Molecular Results After Brochoscopy (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01328873, which also lists 3 linked publications.
