What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new device called AIRE, which may help diagnose small intestinal bacterial overgrowth (SIBO). SIBO occurs when excessive bacteria grow in the small intestine, causing symptoms like bloating and stomach pain. Current tests for SIBO lack accuracy, so the trial aims to determine if AIRE, a handheld breath analyzer, can improve diagnosis by measuring hydrogen levels in the breath. Suitable candidates for this trial have experienced ongoing digestive issues for more than three months and have received a SIBO diagnosis from their doctor. Participants will need a smartphone with Bluetooth to use the device. As an unphased trial, this study offers patients the chance to contribute to innovative research that could enhance SIBO diagnosis.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you have used antibiotics in the last 30 days.

What prior data suggests that this device is safe for diagnosing SIBO?

Studies have shown that a hydrogen breath test safely checks for small intestinal bacterial overgrowth (SIBO). The AIRE device, a handheld breath analyzer, is available and widely used. It measures hydrogen in breath to help identify SIBO.

Research indicates that people generally find the AIRE device easy to use, with many safely performing tests at home. These studies report no harmful side effects, suggesting the device is safe for those considering joining a clinical trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Most treatments for Small Intestinal Bacterial Overgrowth (SIBO) involve antibiotics that target bacterial overgrowth directly. However, the AIRE device offers a different approach by using a hydrogen breathalyzer to help diagnose SIBO through breath analysis. Researchers are excited about this method because it provides a non-invasive, quick way to identify SIBO, potentially leading to faster and more accurate diagnosis. This could allow for more targeted treatment plans, improving patient outcomes and reducing unnecessary antibiotic use.

What evidence suggests that this breath analyzer is effective for diagnosing SIBO?

Studies have shown that the AIRE device, used by participants in this trial, can effectively measure hydrogen levels in breath, crucial for diagnosing small intestinal bacterial overgrowth (SIBO). Research indicates that the device's results align with other breath tests, such as lactulose and glucose tests, showing about a 33% positive detection rate. This handheld breath analyzer is easy to use and helps identify SIBO by detecting excess hydrogen, a sign of bacterial overgrowth. While traditional tests are accurate about 50% of the time, the AIRE device provides a practical, portable option for home testing. ^{6 7 8 9 10}

Are You a Good Fit for This Trial?

This trial is for adults over 18 with chronic gastrointestinal symptoms like nausea, bloating, or abdominal pain and a clinical diagnosis of SIBO. Participants must be able to eat normally and use a smartphone with Bluetooth. Those on recent antibiotics, with inflammatory bowel disease, or on restrictive diets cannot join.

Inclusion Criteria

Access to a smartphone with Bluetooth capability

I have had GI symptoms like nausea or bloating for over 3 months due to scleroderma.

I can undergo the lactose breath test.

Exclusion Criteria

I have a history of inflammatory bowel disease.

I have taken antibiotics in the last 30 days.

You are currently on a special diet, like a low FODMAP diet.
