Abstract:
BACKGROUND:Adverse events (AE) represent a significant clinical problem after infusion of cryopreserved HPC. However, the factors playing a role in the pathogenesis have not yet been fully established. METHODS:We prospectively collected data on AE that occurred with 179 HPC infusions performed on patients affected with hematologic neoplasm after high-dose chemotherapy. The stem cell source was hemopoietic progenitor cells aphaeresis (HPC-A) in 157 cases and hemopoietic progenitor cell BM (HPC-BM) in 22 cases. In all cases, an endotoxin-free DMSO was used. RESULTS:One or more AE were registered in 51/179 infusions (28.6%). The frequency of AE was higher after HPC-A than after HPC-BM (31.3% vs. 4.5%; chi(2) test, P =0.008). With univariate logistic regression, other factors found important for AE were age (P =0.028), number of total nucleated cells infused per kilogram (P =0.002), volume per kilogram infused (P =0.057), volume of packed RBC (P =0.019), a content of non-mononuclear cells >0.5 x 10(8)/kg (
0.5 x 10(8)/kg (P =0.0003) remained significant. A significant correlation existed between reduction of cardiac frequency both with volume per kilogram infused (r =0.221, P =0.02) and actual time of infusion (r =0.269, P =0.005). DISCUSSION:Cardiovascular changes are influenced by volume per kilogram infused and by actual time of infusion, while non-cardiovascular AE are dependent on patient age and contamination by non-mononuclear cells in apheretic harvests.
