Application of the National Comprehensive Cancer Network-distress thermometer in pediatric patients during autologous and allogeneic hematopoietic stem cell transplantation and relationship to blood parameters of the stress axis

Abstract

Abstract Purpose Hematopoietic stem cell transplantations (HSCT) are extremely stressful procedures for pediatric patients. The activation of the hypothalamic pituitary adrenocortical axis (HPA) can influence the immune system negatively and therefore the overall outcome. The distress thermometer (DT) is an easy to use tool for the self-assessment of perceived distress. Methods In this prospective study, a DT with an attached problem list was used in 40 pediatric patients undergoing HSCT and in one parent of each patient. The patients were aged 10–18 years. The patients' cortisol, thyroid stimulating hormone, free triiodothyronine and thyroxine levels were measured regularly during the in-patient stay. Results After admission to the hospital, the stress levels of the pediatric patients and their parents increased and reached their maximum on the day of HSCT. The overall stress values of the parents were higher than those of their children. There was a significant difference in the parents’ stress levels on the day of HSCT, as compared to their stress levels on other days. The mean cortisol values of the pediatric patients also increased after admission, reaching significant elevated levels above the upper normal limit 1 week after HSCT and on discharge day. Although the pediatric patients experienced mainly exhaustion, especially on the day of transplantation, their parents mainly felt worry and anxiety. Interestingly, the rate of worry among children increased in the post-transplant period and reached its maximum on the day of discharge. Conclusions In summary, a significantly increased stress level is shown for both the patients and their parents. This is reflected for the patients both in the DT scores and in the increased cortisol values. For the parents, the focus is primarily on worry and anxiety, for the patients primarily on exhaustion and worry.
