What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing whether taking probiotics can help people with Type 1 diabetes by improving their gut health and reducing inflammation. Previous studies have shown that probiotics can reduce inflammation and improve gut health in both animals and humans with Type 1 diabetes.

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 have used probiotics within 1 month before the screening. If you have a severe, active disease that requires chronic medication, you may not be eligible, except for well-controlled autoimmune thyroiditis/hypothyroidism.

Is the probiotic treatment safe for humans?

Probiotic supplementation, including products like Visbiome, has been well-tolerated in studies, with high participant adherence and no reported adverse events, suggesting it is generally safe for human use. ^{1 2 3 4 5}

How does the treatment Visbiome differ from other treatments for type 1 diabetes?

Visbiome is a probiotic treatment that aims to improve gut health and reduce inflammation, which may help manage type 1 diabetes by addressing gut microbiota imbalances. Unlike traditional treatments that focus on insulin regulation, Visbiome targets the gut environment to potentially modify disease progression. ^{1 4 5 6 7}

What data supports the effectiveness of the treatment Visbiome for Type 1 Diabetes?

Research suggests that probiotics, like those in Visbiome, may help reduce inflammation, which is linked to Type 1 Diabetes. A study showed that probiotics could lower inflammation in siblings of Type 1 Diabetes patients, indicating potential benefits for managing the condition. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

This trial is for boys and girls aged 5-17 who were diagnosed with Type 1 diabetes in the last 90 days, have certain autoantibodies, haven't used immunomodulatory drugs, and show a specific level of insulin production. It's not for those on chronic meds (except controlled thyroid issues), pregnant teens, or recent probiotic users.

Inclusion Criteria

Your body produces a certain amount of a substance called C-peptide after eating a meal. If the amount is higher than a certain level, you may not be able to participate in the study.

I have tested positive for diabetes-related autoantibodies.

I have not received any immune system modifying treatments.

Exclusion Criteria

I am not pregnant and can have children.

Any condition that, in the investigator's opinion, may compromise study participation or may confound the interpretation of the study results

I have diabetes, but it's not Type 1.

Published Research Related to This Trial

In a study involving 96 children aged 8-17 with newly diagnosed type 1 diabetes, the probiotics Lactobacillus rhamnosus GG and Bifidobacterium lactis Bb12 did not significantly improve beta-cell function compared to a placebo over a 6-month period.

While there were no severe adverse effects reported, the probiotic group showed a higher incidence of thyroid autoimmunity, although this was also present at baseline, indicating the need for further research to determine the safety and efficacy of these probiotics in managing type 1 diabetes.

The study will involve 96 children aged 8 to 17 with newly diagnosed type 1 diabetes, testing the effects of probiotics Lactobacillus rhamnosus GG and Bifidobacterium lactis Bb12 on beta-cell function over 6 months.

The primary outcome will measure changes in C-peptide levels after meals, which is crucial for assessing insulin production and beta-cell function in these children.

Probiotic supplementation significantly reduced fasting blood glucose levels in type 1 diabetes mellitus (T1DM) patients, with a decrease of about 31.24 mg/dL based on a meta-analysis of five randomized controlled trials involving 356 participants.

Despite the positive effect on fasting blood glucose, probiotics did not show significant improvements in other key measures like HbA1c, C-peptide, or insulin requirements, indicating that while they may help with blood sugar control, more research is needed to fully understand their role in T1DM management.

A 6-week trial of a dietary supplement containing high-amylose maize-resistant starch modified with acetate and butyrate (HAMSAB) in adults with long-standing type 1 diabetes (T1D) showed increased levels of beneficial short-chain fatty acids (SCFAs) in stools and plasma, indicating a positive shift in gut microbiota composition.

While the supplement did not change glucose control or insulin requirements overall, participants with the highest SCFA levels experienced better glycemic control, suggesting that targeting dietary SCFAs could help improve immune profiles and promote better management of T1D.
