He discovers chronic kidney disease only by breathing

Researchers from the University of Rome, Tor Fergata, developed a specialized surgical mask that could Discover chronic kidney disease (ERC) Patient breath analysis only.

The results of the study were published in ACS Scientific Journal and indicates that this technology can Facilitate early diagnosis and Unfortunate monitoring of ERC.

What is chronic kidney disease?

ERC occurs when the kidneys gradually lose its ability to liquidate the body’s metabolism waste. According to the Civil Hospital in GuadalajaraEstimate that About 11 % of the Mexican population suffer from this disease Mexico was a pioneer in the number of people who needed dialysis. Many cases are not diagnosed on timeBecause in its early stages, it may not have clear symptoms.

Currently, the diagnosis is done By analyzing blood and urine to detect the volatileBut researchers seek Economic and non -expanded alternatives Which allows to determine the disease more easily.

How does the mask work?

The developed device using Italian equipment uses an integrated chemical sensor between the eliminated mask layers. This sensor consists of silver electrodes coated with a conductor polymer, modified with the Porphyrin, and sensitive chemical compounds for some gases.

When a person with a kidney disease, he releases high levels of ammonia and other volatile compounds such as ethanol, bobanol and anustune. The sensor interacts with these gases, which generates a measurable change in the electrical resistance, which is then analyzed by an electronic reader connected by the cables.

What results did the study showed?

The team tested the mask in 100 people, including nearly half of them had a confirmed diagnosis of ERC. The sensor is able to identify patients who suffer from kidney disease properly in 84 % of cases (real positive) and people who have no disease in 88 % of cases (real negative).

The researchers also noted that the collected data can help estimate the ERC stadium, which is linked to clinical management and medical decision -making.

“The implementation of this technology is expected to improve the management of patients who suffer from ERC by facilitating timely identification of changes in the development of the disease,” said Sergio Bernardini and Niessa Nook, authors of the study.

Advantages against traditional methods

Using a mask equipped with chemical sensors is an option with many advantages:

• Not expanded, unlike blood tests.
• Economic, compared to laboratory tests.
• Portable and easy to use, even from clinical environments.
• Continuous monitoring capabilities, useful in patients with previous diagnosis.

Although the sensor does not replace the current clinical methods, it can It is used as a quick examination tool Or as part of the detection programs in the population with high risk of ERC.

The following steps for the mask

The study is progressing in the development of portable techniques and early diagnosis on the basis of human respiration.

The researchers note that more tests in wide and varied groups are required, as well as improvements in the e -reader minimization of the final marketing.
