Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that active infections requiring antibiotics, other than known preventive medications, are excluded, which might imply some restrictions. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment Neocate Splash for inflammatory bowel disease?

Research shows that elemental diets can reduce symptoms like stool frequency and inflammation in patients with inflammatory bowel disease, suggesting that Neocate Splash, as an elemental diet, might be effective in managing these conditions. ^{1 2 3 4 5}

Is the elemental diet safe for humans?

Research shows that an elemental diet can be safely administered to patients with inflammatory bowel disease, with only temporary mild symptoms like nausea and bloating in some cases. ^{1 5 6 7 8}

How is the treatment Neocate Splash unique for inflammatory bowel disease?

Neocate Splash, an elemental diet, is unique because it provides nutrition in a form that is easily absorbed by the body, reducing inflammation and improving intestinal integrity without the need for starter regimens. It is administered through a nasogastric tube, allowing for constant infusion, which can lead to increased nutrient intake and improved nitrogen balance, making it different from traditional drug therapies. ^{1 2 3 9 10}

What is the purpose of this trial?

Background: Bacteria that live inside the stomach and intestines are important for health. Chronic granulomatous disease (CGD) and inflammatory bowel disease (IBD) can make people have unhealthy bacteria. This can lead to gastrointestinal (GI) problems. Researchers want to see if people with CGD and IBD feel better when they change the bacteria in the stomach by following a special liquid diet. Objective: To see if an elemental diet can change the bacteria in the stomach and intestines of people with CGD and IBD. Also, to see if this helps GI symptoms. Eligibility: People ages 8-65 years with CGD, CGD-associated colitis, and IBD. Design: Participants will first be screened with: Upper GI endoscopy and/or colonoscopy. A long, thin tube with a tiny camera at the end will be passed into the participant s body through the mouth or anus. Tissue will be collected. Participants will be sedated for the procedure. They will be sedated using a special mask or small plastic tube placed in an arm vein using a needle. Participants will be put on the special diet for up to 4 weeks. They will stay in the hospital for up to 2 weeks. They will have check-ups. They will have blood, urine, and stool samples collected. They will keep a symptom diary to record how they feel and any GI symptoms. Participants will have 2 follow-up visits. The first will be right after they finish the diet. The second will be 4 weeks later. They will have blood, urine, and stool samples collected. They will learn about re-introducing other foods into their diet.

Eligibility Criteria

This trial is for people aged 8-65 with Chronic Granulomatous Disease (CGD) and Inflammatory Bowel Disease (IBD). They should have certain levels of disease activity, be willing to stay in the hospital for up to two weeks, and consent to genetic testing. Pregnant individuals or those with conditions that make participation unsafe are excluded.

Inclusion Criteria

Able to provide informed consent

I am willing to have genetic tests done on my samples.

I am between 8 and 65 years old.

Exclusion Criteria

Pregnancy

Any condition that, in the opinion of the investigator, contraindicates participation in this study will be excluded from study participation.

I am currently on antibiotics for an infection, not just for prevention.

Treatment Details

Interventions

• Neocate Splash

Trial Overview The study tests if an elemental diet called Neocate Splash can improve gut health by changing stomach bacteria in patients with CGD and IBD. Participants will follow this liquid diet for up to four weeks, starting with a hospital stay, while their symptoms and health markers are monitored.

Participant Groups

Group I: 1 Experimental Treatment 1 Intervention

Participants will be on this diet for 4 weeks. The amount per serving will be determined on the basis of the participant s weight and caloric needs, as determined by a staff dietician.

Findings from Research

Diet plays a significant role in the onset and severity of inflammatory bowel diseases (IBDs), as it can influence immune system regulation and intestinal health.

While enteral nutrition is effective for treating pediatric Crohn's disease, there is a lack of research on the impact of whole food dietary interventions, highlighting the need for further studies to explore dietary patterns and their potential in managing IBD.

Elemental diets, used alongside drug therapy, show therapeutic effectiveness in treating active Crohn's disease, particularly in cases of small bowel involvement, comparable to traditional treatments like salazosulfapyridine and corticosteroids.

The elemental diet leads to physiological changes that may contribute to its effectiveness, such as reduced gastric and pancreatic secretions, altered gut bacteria, and improved nutrient absorption, making it suitable for conditions like acute small bowel disease and malnourishment.
