In 173 patients free of bronchiolitis obliterans syndrome at least 6 months post-transplant, having 10 or more colony-forming units of mesenchymal cells in bronchoalveolar lavage fluid carried a >5.0 hazard ratio for subsequently developing BOS. The relation persisted after multivariate analysis, report Badri et al. AJRCCM 2011;183:1062-1070.
Fang et al prospectively observed 126 patients undergoing lung transplant at 9 U.S. centers. PA pressure was obtained invasively in the OR just after transplant. Those who developed grade 3 primary graft dysfunction at 72 hours (1′ endpoint) had mPAP of 38.5 mm Hg, compared to 29.6 for those who did not; the relationship persisted [… read more]

In a very small trial (n=24), inhaled RNA (ALN-RSV01) appeared to improve outcomes in lung transplant patients with RSV respiratory infections, by interfering with viral replication. Symptoms were reduced, and at 90 days, incidence of bronchiolitis obliterans syndrome was 6% vs 50% in the control group. AJRCCM 2011;183:531-538.
