Oral Hydrogen Peroxide Delivery for Inflammatory Bowel Disease
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for inflammatory bowel diseases like ulcerative colitis and Crohn's disease are inadequate in effectively addressing the underlying bacterial virulence and immune response issues, particularly in maintaining epithelial health and reducing inflammation.
Innovation Solution
The use of hydrogen peroxide, either directly or through a generator system, is administered via an oral or inhalable delivery system to target the gastrointestinal tract or airways, downregulating bacterial virulence factors and enhancing the body's antimicrobial defenses by stimulating NOX1 and DUOX2 activity, thereby reducing disease pathology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatments are used for inflammatory bowel disease, then current standard therapy is maintained, but bacterial virulence and inflammation are not effectively addressed
Solution Approach 1:
The patent applies this principle by utilizing hydrogen peroxide, which can be harmful to bacteria at certain concentrations, to downregulate bacterial virulence factors. The hydrogen peroxide triggers a stress response in pathogens that paradoxically reduces their pathogenicity, converting a potential harmful agent into a beneficial therapeutic tool for reducing bacterial virulence and treating IBD.
Solution Approach 2:
The patent employs parameter changes by modulating the concentration and timing of hydrogen peroxide administration. By controlling the dosage parameters and using delivery systems that release hydrogen peroxide at specific locations and times, the treatment optimizes the downregulation of virulence factors while minimizing harmful effects, thereby improving treatment effectiveness.
2Object-generated harmful factors
If hydrogen peroxide is administered to downregulate bacterial virulence, then bacterial virulence factors are reduced, but potential tissue damage from hydrogen peroxide may occur
Solution Approach 1:
The patent applies local quality by using delivery systems that target hydrogen peroxide release to specific locations in the gastrointestinal tract where bacterial virulence is most problematic. This localized approach ensures that hydrogen peroxide is concentrated at sites of infection and inflammation, maximizing its effect on bacterial virulence while minimizing exposure to and damage of surrounding healthy tissue.
Solution Approach 2:
The patent employs partial action by administering controlled, low doses of hydrogen peroxide that are sufficient to trigger the downregulation of virulence factors but insufficient to cause significant tissue damage. This partial action approach leverages the threshold effect where moderate hydrogen peroxide levels activate protective immune responses and reduce bacterial pathogenicity without overwhelming the tissue with harmful oxidative stress.
3Reliability
If hydrogen peroxide levels are increased to enhance antimicrobial defenses, then immune response is improved, but oxidative stress may be increased
Solution Approach 1:
The patent applies feedback by utilizing the body's existing antioxidant systems and immune responses as a regulatory mechanism. The administered hydrogen peroxide triggers a feedback loop where the host's antioxidant defenses are upregulated, and the immune system responds to control bacterial infections. This feedback mechanism ensures that hydrogen peroxide levels remain within a therapeutic window that enhances antimicrobial defense while preventing excessive oxidative stress.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach accelerates recovery, reduces inflammation, and supports tissue restitution by downregulating bacterial virulence and enhancing the body's antimicrobial defenses, providing a localized and sustained increase in hydrogen peroxide levels at the target site.
Implementation Method 1
hydrogen peroxide act as a potent, negative regulator of the LEE pathogenicity island in attaching and effacing (A/E) human and murine enteropathogenic E. coli resulting in downregulation of bacterial virulence factors
Implementation Method 2
stimulating NOX1 and DUOX2 activity, thereby reducing disease pathology

AI summary
A delivery system comprising hydrogen peroxide or a hydrogen peroxide generator system, for use in a method for the treatment or prevention of inflammatory bowel disease in a mammal, is described. The method comprises a step of orally administering to the mammal the delivery system, wherein the delivery system is formulated for oral delivery and release of the hydrogen peroxide or hydrogen peroxide generator system in-situ at a target location in the mammalian gastrointestinal tract. Also described is an oral dosage delivery system comprising hydrogen peroxide or a hydrogen peroxide generator system, in which the delivery system is configured for oral administration to a mammal and release of the hydrogen peroxide or hydrogen peroxide generator system at a target location within the mammalian gastrointestinal tract thereby effecting a localised increase in hydrogen peroxide levels at the target location in the mammalian gut or airways.
