AbstractIntroductionOral mucositis is regarded by patients as one of the worst and debilitating complications of conditioning and hematopoietic cell transplantation (HCT). Prevention of mucositis is one of the priorities of supportive therapy during and after conditioning.ObjectivesThe primary objective of the study was the analysis of efficacy of keratinocyte growth factor (KGF, palifermin) used in prophylaxis of oral mucositis in patients undergoing allo-HCT. The secondary objectives of the study included the analysis of the influence of palifermin on clinical course of oral mucositis and early transplant outcomes, as well as analysis of the contraindications of palifermin in patients undergoing allo-HCT.Patients and methodsA total number of 253 allo-HCT performed between 2003 and 2018 in patients aged 0–19 years in a single center were analyzed. Overall, in 161 HCTs, palifermin was administered.ResultsPatients receiving KGF were transplanted earlier in the context of calendar year, and more often received ATG, mainly due to the higher rate of unrelated donor transplants. Allo-HCT patients who were administered palifermin had shorter time of mucositis (median: 9 vs. 13 days, p < 0.001), lower mucositis grade (median: 2° vs. 3°; p < 0.001), shorter period of total parenteral nutrition (median: 19 vs. 22 days; p = 0.018), and lower incidence of episodes of febrile neutropenia (median: 39.1% vs. 83.1%; p < 0.001).ConclusionsThe use of palifermin has decreased duration and severity of oral mucositis in children after allo-HCT. Palifermin is a safe and well-tolerated compound in children undergoing allo-HCT.

(1) Background: survivors of allogeneic hematopoietic cell transplantation (alloHCT) suffer from morbidity and mortality due to cardiovascular events. We hypothesized that vascular injury and pro-coagulant activity are evident in alloHCT survivors without existing alloHCT complications or relapse. (2) Methods: we enrolled consecutive adult alloHCT survivors without established cardiovascular disease and control individuals matched for traditional cardiovascular risk factors (January–December 2019). Circulating microvesicles (MVs) of different cellular origins (platelet, erythrocyte, and endothelial) were measured by a standardized flow cytometry protocol as novel markers of vascular injury and pro-coagulant activity. (3) Results: we recruited 45 survivors after a median of 2.3 (range 1.1–13.2) years from alloHCT, and 45 controls. The majority of patients suffered from acute (44%) and/or chronic (66%) graft-versus-host disease (GVHD). Although the two groups were matched for traditional cardiovascular risk factors, alloHCT survivors showed significantly increased platelet and erythrocyte MVs compared to controls. Within alloHCT survivors, erythrocyte MVs were significantly increased in patients with a previous history of thrombotic microangiopathy. Interestingly, endothelial MVs were significantly increased only in alloHCT recipients of a myeloablative conditioning. Furthermore, MVs of different origins showed a positive association with each other. (4) Conclusions: endothelial dysfunction and increased thrombotic risk are evident in alloHCT recipients long after alloHCT, independently of traditional cardiovascular risk factors. An apparent synergism of these pathophysiological processes may be strongly involved in the subsequent establishment of cardiovascular disease.
