PG - 461-6 LID - 10.1111/j.1600-0609.2008.01149.x [doi] AB - We retrospectively analyzed 23 cases with early-onset idiopathic pneumonia syndrome (IPS) of 192 patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) from April 1997 to October 2007. Risk factors for IPS development were evaluated using Cox proportional hazards model, including age, gender, underlying disease, disease status at transplant, transplant type, conditioning regimens, donor type, acute graft-vs.-host disease (GVHD), severity of acute GVHD (aGVHD), human leukocyte antigen (HLA) disparity, and organ involvement of aGVHD. Factors that were significant at the 0.1 level on univariate analysis were evaluated by multivariate analysis. Twenty-three of 192 patients developed IPS (12.0%). Median time to IPS onset after allogeneic HSCT was 76 d (range 32-120 d); median time to death after the diagnosis of IPS was 9 d (range 3-92 d); 20 patients with IPS died because of the rapid progression of respiratory failure (87.0%). Nineteen patients with IPS developed aGVHD (82.6%), with grade III-IV aGVHD in 11 patients (47.8%) and aGVHD of gut in 16 patients (69.6%). The following six factors were associated with an increased risk of IPS by univariate analysis: not in remission, unrelated donor, HLA disparity, occurrence of aGVHD, grade III-IV aGVHD and aGVHD of gut. These risk factors were entered into a multivariate analysis model. Only unrelated donor, grade III-IV aGVHD and aGVHD of gut are identified as being significantly associated with the occurrence of IPS, and among them, aGVHD of gut was associated with the largest risk of IPS, suggesting that the lung may be a target organ of aGVHD.
