Thiamine Use in Hospitalized Patients: A Clinical Review.

Area of Science:

• Biochemistry
• Clinical Nutrition
• Internal Medicine

Background:

• Thiamine (vitamin B1) is essential for human metabolism.
• Dietary sources include grains, legumes, and pork.
• Deficiency can result from short bowel syndrome, malnutrition, alcohol use, or diuretics.

Purpose of the Study:

• To review indications for thiamine supplementation in hospitalized patients.
• To analyze historical and emerging uses of thiamine.
• To propose a framework for thiamine supplementation.

Main Methods:

• Literature review of thiamine supplementation.
• Analysis of studies on thiamine use in various clinical scenarios.
• Synthesis of evidence for supplementation guidelines.

Main Results:

• Thiamine supplementation is a primary treatment for Wernicke's encephalopathy.
• It's used to prevent deficiency during refeeding in at-risk patients.
• Emerging research explores its use in sepsis, lactate clearance, and delirium.

Conclusions:

• Thiamine deficiency requires prompt identification and treatment.
• Supplementation is crucial for specific conditions like Wernicke's encephalopathy and refeeding syndrome.
• Further research supports expanding thiamine use in critical care settings.
