Summary

This trial tests whether giving intravenous thiamine (vitamin B1) alongside standard treatment helps people with diabetic ketoacidosis recover faster. Diabetic ketoacidosis is a serious condition where the blood becomes too acidic. The study includes adults hospitalized with this condition and compares thiamine to a placebo. Researchers will measure how quickly acidosis resolves and whether hospital stays are shortened.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
thiamine (vitamin B1)
What this could lead to
If it works, this could speed up recovery from diabetic ketoacidosis and reduce hospital stays.
What could go wrong
This is a small Phase 2 trial, so results may not be conclusive. Thiamine is generally safe, but it may not provide added benefit over standard care.
