AbstractBackground:High-dose chemotherapy and haematopoietic stem cell transplantation are essential for patients with paediatric haematologic diseases, although cardiotoxicity remains a concern. Heart rate variability analysis can evaluate autonomic nervous function interactions with cardiac function.Objective:This study aimed to characterise heart rate variability differences between patients undergoing chemotherapy and controls, and the effects of haematopoietic stem cell transplantation on the autonomic nervous system in patients with haematological malignancies.Methods:Nineteen patients (11 male, median age: 11.6 years) who received conventional chemotherapy followed by transplantation and 19 non-transplant patients (10 male, median age: 11.5 years) receiving chemotherapy only between 2006 and 2018 for haematological malignancies were retrospectively enrolled. Data from 24-hour Holter monitoring were recorded after chemotherapy and before and after transplantation. Heart rate variability was analysed in patients and 32 matched normal controls.Results:There were significant differences between patients and normal controls in all heart rate variability analysis parameters apart from coefficient of variation of RR interval and standard deviation of the average normal RR interval for all 5-minute segments during sleeping. There was a significant difference in the cumulative anthracycline dose and heart rate variability during sleep between the non-transplant and pre-transplant groups. We observed no remarkable differences in time-domain analysis parameters between before and after transplantation, although the low-frequency component of power-spectrum analysis during awake hours was significantly decreased after transplantation.Conclusion:Conventional chemotherapy for paediatric haematologic diseases may be a risk factor for autonomic dysfunction. Further declines in heart rate variability after transplantation appear minor.

Over Time

Background: Oligoclonal bands (OCB) are widely believed to be stable over time and rarely affected by disease-modifying treatment in MS. It is presently unknown how intrathecal immunoglobulin production and other cerebrospinal fluid (CSF) biomarkers are impacted by a highly efficacious procedure such as autologous haematopoietic stem cell transplantation (aHSCT). Objective: To describe the evolution of intrathecal immunoglobulin and neurofilament light (NFL) over time in MS patients treated with aHSCT. Methods: In this retrospective study, available data from previously made CSF investigations in 46 patients treated with aHSCT were analysed. Results: After a median follow-up time of 745 days, immunoglobulin G (IgG) OCB remained detectable in 74% of patients, the proportion of patients with a pathological IgG index went down from 70% to 46%, and the proportion of patients with a pathological NFL went down from 72% to 24%. In patients with follow-up time >1500 days, IgG OCB were detectable in 50% of patients, 14% had a pathological IgG index and none a pathological NFL. Conclusions: Intrathecal immunoglobulin production and NFL were lower after treatment with aHSCT, decreased over time and were normalised in a significant portion of patients. This challenges the notion that OCB are unaffected by therapeutic intervention in MS.
