Pre-operative and post-operative spirometry in bone marrow transplant patients

Area of Science:

• Pulmonary Medicine
• Hematology
• Transplant Surgery

Background:

• Bone marrow transplantation (BMT) is a complex procedure with potential for significant pulmonary complications.
• Assessing pre-transplant pulmonary function is crucial for patient management and outcome prediction.

Purpose of the Study:

• To analyze pre-operative spirometry findings in BMT patients.
• To determine the predictive value of spirometry for postoperative pulmonary complications and mortality.
• To explore correlations between spirometry results and transplant outcomes.

Main Methods:

• Retrospective analysis of spirometry data from 120 BMT patients (age >12).
• Evaluation of parameters including transplant type, underlying disease, CMV serology, cell source, smoking, prior lung issues, and transplant rejection.
• Comparison of pre- and post-operative spirometry findings with clinical outcomes.

Main Results:

• 13.3% of patients had pre-operative spirometry alterations (obstruction, restriction, or mixed patterns).
• 24.2% had post-operative alterations. Post-operative changes were linked to acute rejection, age >30, female sex, and stem cell transplants.
• History of lung disease and chronic rejection correlated with increased mortality; pre-operative spirometry did not predict mortality.

Conclusions:

• Pre-operative spirometry alterations in BMT patients do not reliably predict postoperative pulmonary complications or mortality.
• Spirometry findings were not determinant in assessing BMT candidacy.
• Simple spirometry appears to have minimal practical utility in the pre-transplant evaluation of these patients.
