Lung probe aims to cut antibiotic overuse

Health Desk—March 31, 2017: Researchers believe that a new lung probe that diagnoses bacterial infections could prevent unnecessary use of antibiotics in intensive care units.

The fibre-optic tube can show within 60 seconds whether a patient needs to be treated with the drugs, according to the sources.

The researchers claim that proteus technology can tackle the emergence of bacteria that are resistant to antibiotics.

Proteus has received £2m of funding from the Wellcome Trust.

It will also be boosted by nearly £1m from the CARB-X antibiotic resistance project co-funded by the US government and Wellcome.

Proteus uses chemicals that light up when they attach to specific types of bacterial infection.

This fluorescence is detected using fibre-optic tubes that are small enough to be threaded deep inside patients' lungs.

The research team hope it could "revolutionise the way critically-ill patients and others with long-term lung conditions are assessed and treated".

Doctors currently rely on X-rays and blood tests for diagnosis, but these can be slow and imprecise.

Patients are often treated with antibiotics as a precaution, which exposes them to potential side effects.

Dr Kev Dhaliwal, who is leading the project at the University of Edinburgh, said, "We need to understand disease in patients better so that we can make better decisions at the bedside’’.

Tim Jinks, of the Wellcome Trust, said: "Drug-resistant infection is already a huge global health challenge - and it is going to get worse.

"We need global powers to work together on a number of fronts - from the beginning to the end of the drug and diagnostic development pipeline."

The project has been developed by scientists at the universities of Edinburgh, Heriot-Watt and Bath.
