Thiamine deficiency observed in a cancer patient's caregiver

Objective Thiamine deficiency (TD) is recognized in various kinds of disease with associated loss of appetite including cancer; however, TD has not been recognized in the family caregivers of cancer patients to date. Method From a series of cancer patient caregivers, we reported an aged family caregiver who developed TD while caring for the cancer patient. Result The caregiver was a 90-year-old male. He had been accompanying his wife, who was diagnosed with colon cancer 4 years previously, on hospital visits as the primary caregiver, but because of psychological issues, he was recommended to visit the psycho-oncology department's “caregiver's clinic” for a consultation. Detailed examination revealed that his appetite had been only about 50% of usual from about one year before, and he had lost 12 kg in weight in one year. The diagnosis of TD was supported by his abnormally low serum thiamine level. Significance of the results This report demonstrates that there is a possibility that care providers could develop TD from the burdens associated with caregiving. TD should be considered whenever there is a loss of appetite lasting for more than 2 weeks, and medical staff should pay careful attention to the physical condition of care providers to prevent complications resulting from TD.
