Thiamine and diabetes: back to the future?

Area of Science:

• Endocrinology
• Nutritional Science
• Diabetology

Background:

• Historical links between thiamine (vitamin B1) and diabetes date back to the 1940s.
• Thiamine deficiency is implicated in diabetic neuropathy, with supplementation showing potential benefits.
• Evidence suggests thiamine's positive effects on microvascular cells involved in diabetic complications since 1996.

Purpose of the Study:

• To review the existing evidence on thiamine's role in managing diabetic complications.
• To highlight the potential of thiamine and benfotiamine in treating diabetic neuropathy and microangiopathy.
• To identify the gap in research regarding thiamine's effect on diabetic retinopathy.

Main Methods:

• Review of historical reports and scientific literature on thiamine and diabetes.
• Analysis of in vitro and animal models investigating thiamine's effects on microvascular cells.
• Evaluation of pilot studies on thiamine's impact on diabetic nephropathy.

Main Results:

• Thiamine and benfotiamine gained acceptance for diabetic neuropathy treatment in the late 1990s.
• Studies indicate beneficial effects of thiamine on diabetic microangiopathy and nephropathy.
• The role of thiamine in preventing or treating diabetic retinopathy remains largely uninvestigated.

Conclusions:

• Thiamine is a safe, water-soluble vitamin with demonstrated benefits for certain diabetic complications.
• Lack of patentability hinders large-scale clinical trials, impeding further investigation and potential therapeutic application.
• Diabetic patients may be missing out on a potential therapeutic strategy due to research funding limitations.
