ABSTRACT

Background

There is a lack of studies analyzing the association between oral mucositis (OM) and nutritional imbalance in children during hematopoietic stem cell transplantation (HSCT). The aim of this study was to compare the risk factors for OM and nutritional imbalance during HSCT in pediatric patients with nonmalignant diseases (NMD) and malignant diseases (MD).

Methods

Data on age, sex, primary disease, transplantation type, conditioning regimen, GVHD prophylaxis, gastrointestinal toxicity, OM, percent body weight loss or gain, nutritional repositioning, and overall survival (OS) were retrospectively collected from the 132 medical records. The data were then compared between patients with NMD (n = 70) and MD (n = 62).

Results

OM had a similar severity between the groups. The primary risk factor for OM in the NMD group was the conditioning regimen with busulfan, while in the MD group it was GVHD prophylaxis with cyclosporin and methotrexate. OM did not have an impact on body weight loss or gain in any of the groups. In the NMD, body weight gain due to fluid overload was more pronounced and associated with a lower age range. OS was similar between the groups and was not affected by OM.

Conclusions

OM pattern was similar in pediatric patients with or without MD, but the factors that determined these oral lesions were different. There were disparities in body weight changes between the two groups, and these changes were not associated to OM.

Conflicts of Interest

The authors declare no conflicts of interest.
