Neurotoxicity presented by patients undergoing hematopoietic stem cell transplantation: a scoping review

Abstract

Objective

To map the types of neurotoxicity presented by patients undergoing Hematopoietic Stem Cell Transplantation.

Methods

This is a scoping review, guided by the method proposed by the Joanna Briggs Institute, and followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews recommendations. The search for studies was carried out between the months of July and August 2020 and took place in databases and in national and international theses and dissertations portals.

Results

The final sample consisted of 71 scientific articles, all in English. There was a highlight for the year 2018 with 14 (19%) publications. There was a prevalence of studies carried out in the United States of America with 29 (40.8%). Regarding the population, all (100%) articles are about patients undergoing hematopoietic stem cell transplantation who presented neurotoxicity. Regarding the chemotherapeutic agents used in the pre-transplantation regimen of hematopoietic stem cells, seven (9.8%) used the combination of Fludarabine and Cyclophosphamide, followed by Cyclosporine and Tacrolimus in six (8.4%), Cyclosporine in four (5.6%), Fludarabine in three (4.2%). As for the neurotoxicity presented in patients undergoing transplantation, the posterior reversible encephalopathy syndrome was evidenced in 19 (26.7%) studies. It should be noted that other studies have identified this syndrome, but have reported different symptoms.

Conclusion

The neurotoxicity presented by patients undergoing hematopoietic stem cell transplantation are posterior reversible encephalopathy, posterior reversible leukoencephalopathy, Wernicke’s encephalopathy, hypertensive encephalopathy, metabolic encephalopathy, limbic encephalopathy, hemorrhagic complications and seizures.
