Thiamine Deficiency Is Common and Underrecognized in Emergency Department Oncology Patients

Area of Science:

• Oncology
• Emergency Medicine
• Nutritional Science

Background:

• Wernicke's encephalopathy in oncology patients can stem from poor thiamine intake, independent of alcohol use.
• High metabolic demands in acute illnesses, common in emergency departments (ED), can worsen thiamine deficiency.
• Oncology patients face increased risk of thiamine deficiency due to poor nutrition and high metabolic needs.

Purpose of the Study:

• To determine the incidence of thiamine deficiency in oncology patients presenting to the ED.
• To identify potential risks and consequences of untreated thiamine deficiency in this population.
• To assess current treatment practices for thiamine deficiency in ED oncology patients.

Main Methods:

• A single-center prospective cohort study design was employed.
• Included were acutely ill oncology patients and age/sex-matched controls without cancer history.
• Whole blood thiamine levels were measured; patients with prior alcohol use or thiamine treatment were excluded.

Main Results:

• Thiamine deficiency was significantly more prevalent in oncology patients (28.7%) compared to controls (8.5%).
• The odds of thiamine deficiency were 4.4 times higher in oncology patients.
• No oncology patients identified with thiamine deficiency received treatment in the ED.

Conclusions:

• Acutely ill oncology patients frequently present with thiamine deficiency.
• There is a substantial and concerning gap in the diagnosis and treatment of thiamine deficiency in this patient group within the ED setting.
• This deficiency poses a risk for Wernicke's encephalopathy and other related disorders if unaddressed.
