Tailored Exercise during Hematopoietic Stem Cell Transplantation Hospitalization in Children with Cancer: A Prospective Cohort Study.

ABSTRACT: We assessed the clinical effects of a supervised exercise (aerobic + resistance) intervention performed during inpatient hospitalization for pediatric hematopoietic stem cell transplantation (HSCT). Patients were placed in an exercise (n = 65 (47 and 18 with allogeneic (allo-) and autologous (auto-) HSCT, respectively)) or a control (n = 53 (39 and 14)) group. Exercise interventions were performed in isolated hospital patient rooms. Patients were followed-up from the beginning of the conditioning phase up to 6 years. We assessed survival, risk of graft-versus-host disease (GvHD) or graft failure (primary outcomes), and engraftment kinetics, supportive care, toxicity profile, and immune reconstitution for auto-HSCT and allo-HSCT. The exercise intervention was safe and did not affect the risk of mortality, acute/chronic GvHD, or graft failure (all p > 0.05). No between-group differences (p > 0.05) were found for the remainder of clinical endpoints, except for a reduced number of total and viral infections in the exercise group after allo-HSCT (unadjusted p = 0.005 for both total and viral infections, and adjusted p = 0.023 and 0.083, respectively). In conclusion, exercise performed during inpatient hospitalization for pediatric HSCT is safe and well tolerated during both auto and allo-HSCT and tends to decrease the risk of infection after allo-HSCT. These findings provide additional support to the notion that a multidisciplinary approach (i.e., including the work of exercise specialists) is suitable in the management of children undergoing HSCT. Further studies are needed to determine whether applying a different training stimulus (notably, higher exercise intensities) exerts positive effects on HSCT prognosis in these patients.

Project description:BackgroundGastrointestinal tract function and it's integrity are controlled by a number of peptides whose secretion is influenced by severe inflammation. In stomach the main regulatory peptide is ghrelin. For upper small intestine cholecystokinin and lower small intestine glucagon-like peptide- 1 are secreted, while fibroblast growth factor-21 is secreted by several organs, including the liver, pancreas, and adipose tissue [12]. Hematopoietic stem cell transplantation causes serious mucosal damage, which can reflect on this peptides.MethodsThe aim of the study was to determine fasting plasma concentrations of ghrelin, cholecystokinin, glucagon- like peptide-1, and fibroblast growth factor-21, and their gene expressions, before and 6 months after hematopoietic stem cell transplantation.27 children were studied, control group included 26 healthy children.ResultsAcute graft versus host disease was diagnosed in 11 patients (41%, n = 27). Median pre-transplantation concentrations of gastrointestinal peptides, as well as their gene expressions, were significantly lower in studied group compared with the control group. Only median of fibroblast growth factor-21 concentration was near-significantly higher before stem cell transplantation than in the control group. The post-hematopoietic transplant results revealed significantly higher concentrations of the studied peptides (except fibroblast growth factor-21) and respective gene expressions as compare to pre transplant results. Median glucagone like peptide-1 concentrations were significantly decreased in patients with features of acute graft versus host disease. Moreover, negative correlation between glucagone like peptide-1 concentrations and acute graft versus host disease severity was found.ConclusionsIncreased concentrations and gene expressions of gastrointestinal tract regulation peptides can be caused by stimulation of regeneration in the severe injured organ. Measurement of these parameters may be a useful method of assessment of severity of gastrointestinal tract complications of hematopoietic stem cell transplantation.

Project description:BackgroundHematopoietic stem cell transplantation (HSCT) is a standard therapy strategy for most malignant disorders in children. However, transplant-related pneumonia remains a major therapy challenge and mesenchymal stromal cells (MSCs) are rarely reported in HSCT-related pneumonia. The aim of our study was to assess the efficacy of MSC for HSCT-related pneumonia in children.MethodsWe retrospectively retrieved HSCT-related (severe and non-severe) pneumonia cases (aged < 18 years), which underwent MSC treatment (MSC group) or non-MSC treatment (non-MSC group) in Guangzhou Women and Children's Medical Center, from December 2017 to December 2019. We investigated outcomes of the two different treatments among severe cases and non-severe cases, respectively. The primary endpoints were differences in overall cure rate and time to cure between MSC and non-MSC groups. The secondary endpoints were 180-day overall survival and cumulative cure rate.ResultsFinally, 31 severe pneumonia cases (16 in MSC group, 15 in non-MSC group) and 76 non-severe cases (31 in MSC group, 45 in non-MSC group) were enrolled in this study. Among severe pneumonia cases, overall cure rate in MSC group was significant higher than that in non-MSC group (12[75.0%] vs. 5[33.3%]; OR = 6.00, 95% CI [1.26-28.5]; p = 0.020); the time (days) to cure in MSC group was dramatically reduced compared with that in non-MSC group (36 [19-52] vs. 62 [42-81]; OR = 0.32, 95% CI [0.12-0.88]; p = 0.009); the 180-day overall survival in MSC group was better than that in non-MSC group (74.5% [45.4-89.6] vs. 33.3% [12.2-56.4]; p = 0.013). Among non-severe pneumonia cases, the time (days) to cure in MSC group was notably decreased compared with that in non-MSC group (28 [24-31] vs. 33 [26-39]; OR = 0.31, 95% CI [0.18-0.56]; p = 0.003). Compared with non-MSC group, MSC-treated patients achieved significant improvements of cumulative cure rate not only in severe pneumonia cases (p = 0.027), but also in non-severe cases (p < 0.001).ConclusionsThis study revealed that MSC treatment could contribute to improving outcomes in children with pneumonia post-HSCT, especially in severe cases. These findings suggest MSC treatment as a promising therapy for HSCT-related pneumonia in children.
