Children undergoing bone marrow transplantation (BMT) may have pre-existing lung function issues. Post-BMT, lung function can change, highlighting the need for ongoing respiratory monitoring in pediatric patients.

Area of Science:

  • Pediatric Pulmonology
  • Hematology-Oncology
  • Transplantation Medicine

Background:

  • Bone marrow transplantation (BMT) is a critical treatment for onco-hematological disorders in children.
  • Respiratory complications can impact outcomes post-BMT.
  • Longitudinal assessment of pulmonary function is crucial for managing pediatric patients.

Purpose of the Study:

  • To prospectively evaluate respiratory function changes in children before and after BMT.
  • To identify potential risk factors affecting lung function post-transplantation.
  • To emphasize the importance of continuous respiratory monitoring in this population.

Main Methods:

  • Prospective study involving clinical exams, chest X-rays, and pulmonary function tests (PFTs).
  • Evaluated parameters included vital capacity (VC), functional residual capacity (FRC), total lung capacity (TLC), forced expiratory volume in 1 s (FEV1), and carbon monoxide diffusing capacity (DLCO).

  • Statistical comparison of pre-BMT, post-BMT, and predicted values using Student's t-test.

    • Main Results:

    • Pre-BMT, children showed lower VC and DLCO, and higher FRC than predicted.
    • Post-BMT, VC, TLC, and FEV1 decreased, while the RV/TLC ratio increased compared to pre-BMT values.
    • Age at BMT was identified as the sole risk factor for decreased lung function; observed abnormalities were not clinically significant.

    Conclusions:

    • Lung dysfunction can be present before BMT and be altered by the procedure.
    • Age at BMT is a significant factor influencing pulmonary function changes.
    • Regular respiratory monitoring and follow-up are essential for optimizing treatment and outcomes in pediatric BMT recipients.
