Thirty-two of 242 allogeneic hematopoietic stem cell transplantation patients had a fluoride level measured because of pain.
After 1 year and 2 years, 15.3% and 35.7% of patients, respectively, had an elevated fluoride level.
Serum creatinine, estimated glomerular filtration rate, alkaline phosphatase, and voriconazole concentration did not predict for fluoride excess and associated pain.
After voriconazole discontinuation, pain resolved (31.8%) or improved (37%) in most patients.
