Rhinosinusitis in Acute Leukemia Patients Undergoing Allogeneic Stem Cell Transplantation-A Single-Center Experience.

BACKGROUND: Although rhinosinusitis constitutes a major clinical problem in general population, data on rhinosinusitis in patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT) are scarce. Therefore, the aim of the study was to assess the frequency of rhinosinusitis, the impact of rhinosinusitis on post-alloHSCT outcome, and to analyze risk factors potentially predisposing to rhinosinusitis. METHODS: Retrospective analysis of acute leukemia patients undergoing alloHSCT. RESULTS: A total of 87 patients (49 male), with a median age of 36 years (range, 18-58), transplanted from 1999 to 2010, were enrolled; 61 patients suffered from acute myeloid leukemia (AML) and 26 of acute lymphoblastic leukemia (ALL). Fifteen patients (17.2%) experienced rhinosinusitis before transplantation, among whom 5 (33%) experienced rhinosinusitis after alloHSCT; 22 patients (25.3%), 12 AML and 10 ALL, experienced rhinosinusitis after alloHSCT. The median time to rhinosinusitis was 200 days (range, 1-2,044). 11 patients experienced rhinosinusitis during the 1st 100 days after transplantation, 8 during the 1st 30 days. Post-alloHSCT rhinosinusitis did not affect overall survival of transplant patients (P = .35). In univariate analysis only total body irradiation as part of conditioning (odds ratio [OR], 2.78; 95% CI, 1-7.77) and previous nasal packing (OR, 5.18; 95% CI, 1.22-23.43) were associated with higher incidence of rhinosinusitis. In multivariate analysis, none of the analyzed parameters was shown to have an impact on rhinosinusitis development. CONCLUSIONS: Rhinosinusitis is a frequent medical condition in patients undergoing alloHSCT. The overall survival of patients developing rhinosinusitis after HSCT is similar to survival of patients who do not. No risk factors for developing rhinosinusitis could be identified.
