[Glucose-induced hyperlactatemias in thiamine deficiency]
Thiamine deficiency can cause dangerous lactate levels when receiving parenteral nutrition with carbohydrates. High-dose thiamine therapy is recommended before carbohydrate administration if deficiency is suspected.
Area of Science:
- Biochemistry
- Nutrition Science
- Medical Research
Context:
- Parenteral nutrition (PN) is limited by dose-dependent hyperlactatemia.
- Thiamine deficiency can exacerbate lactate accumulation, particularly with glucose loads.
- Risk factors include alcohol abuse and conditions like esophageal strictures.
Purpose:
- To investigate the impact of thiamine deficiency on lactate levels during glucose loading in rats.
- To establish the link between thiamine deficiency and potential lactate acidosis in the context of PN.
- To provide recommendations for preventing hyperlactatemia in patients receiving PN.
Summary:
- An eight-week thiamine-deficient diet in rats significantly elevated lactate levels compared to controls.
- Glucose loading in deficient rats led to pronounced hyperlactatemia and acidosis.
- High-dose thiamine therapy is advised prior to carbohydrate-based PN if deficiency is suspected.
Impact:
- Highlights the critical role of thiamine in glucose metabolism during PN.
- Informs clinical practice regarding the prevention of hyperlactatemia in at-risk patients.
- Suggests a proactive therapeutic approach to mitigate PN-related complications.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
