Abstract

Bronchiolitis obliterans syndrome (BOS) is a pulmonary complication of allogeneic hematopoietic cell transplantation (aHCT). Recent National Institutes of Health consensus diagnostic criteria for BOS have not been assessed in a clinical setting. Modified National Institutes of Health diagnostic consensus criteria for BOS were applied to evaluate its prevalence, risk factors, and outcomes in the modern era of aHCT. Pulmonary function tests from 1145 patients were screened to identify patients with new-onset airflow obstruction. Clinical records were reviewed to exclude pulmonary infection and other causes. The overall prevalence of BOS among all transplanted patients was 5.5%, and 14% among patients with chronic graft-versus-host disease (cGVHD). The median time from transplant to meeting spirometric criteria for BOS was 439 days (range: 274-1690). Although many previously identified risk factors were not significantly associated, lower baseline FEV(1)/FVC ratio (P = .006), non-Caucasian race (P = .014), lower circulating IgG level (P = .010), and presence of cGVHD (P < 0.001) were associated with an increase in risk, with the latter associated with a 10-fold increase in risk. Multivariate analysis indicated that BOS conferred a 1.6-fold increase in risk for mortality after diagnosis. These results suggest that the National Institutes of Health diagnostic criteria can reliably identify BOS, and that it is more prevalent than previously suggested. Spirometric monitoring of high-risk patients with cGVHD may permit earlier detection and intervention for this often-fatal disease.
