Can a simple Five-Step protocol save leptospirosis Patients' kidneys?
NCT ID NCT05425524
First seen Oct 02, 2026 · Last updated Oct 02, 2026
Summary
Leptospirosis is a bacterial infection spread through water contaminated by animal urine, and it can lead to serious kidney damage. Researchers at Chulalongkorn University are testing a five-step hospital care bundle for adults admitted with suspected leptospirosis. The bundle guides doctors through rapid testing, antibiotics within an hour of blood cultures, intravenous fluids, and staged management of kidney injury. The trial measures whether patients who receive the bundle have less acute kidney injury in the first 72 hours than those who receive usual care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a five-step hospital care bundle for leptospirosis
- What this could lead to
- If the bundle works, hospitals could adopt a standard set of steps that helps protect leptospirosis patients from acute kidney injury.
- What could go wrong
- The trial may show the bundle does not reduce kidney injury compared with usual care. Results from one hospital setting may not apply everywhere, and the bundle adds steps that could be hard to follow consistently.
