Solution Overview

Problem

Current treatments for dermatitis, such as atopic dermatitis, face challenges including the instability of antibacterial enzymes like endolysins in aqueous solutions and the side effects of conventional steroid creams, as well as the non-specificity and resistance issues with antibiotics, necessitating an improved treatment approach.

Innovation Solution

A method involving the stabilization of proteins, specifically antibacterial endolysins, using a non-aqueous composition with cereal meal, particularly oatmeal, to enhance their stability and efficacy, and a treatment method for atopic dermatitis using these stabilized proteins in a non-aqueous composition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If endolysins are used in aqueous solutions for treating dermatitis, then they can exert their antibacterial effect, but they lose their activity over time due to instability

Engineering Contradiction:
Improvestability of endolysinVSAvoidduration of lytic activity
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent changes the physical state of the endolysin from aqueous solution to lyophilized powder form, and modifies the environmental parameters by incorporating it into a cereal meal matrix. This parameter change transforms the unstable aqueous solution into a stable solid formulation that maintains activity upon reconstitution, directly resolving the stability-duration contradiction.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cereal meal acts as an intermediary carrier that protects the endolysin protein from degradation. The matrix provides a protective environment that stabilizes the protein structure, allowing it to maintain its lytic activity over extended periods while remaining deliverable as a topical treatment for dermatitis.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If conventional steroid creams are used to treat dermatitis, then inflammation can be reduced, but side effects such as skin atrophy and HPA axis suppression occur

Engineering Contradiction:
ImproveinflammationVSAvoidside effects
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of bacterial infection in dermatitis into a beneficial treatment opportunity by using bacteriophage endolysins. These phage-derived enzymes specifically target and lyse bacterial cell walls, transforming the pathogenic bacterial presence into a therapeutic mechanism that eliminates the underlying cause rather than merely suppressing symptoms with steroids.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The treatment employs highly specific local action where endolysins target only the pathogenic bacteria responsible for dermatitis exacerbation. This specificity ensures that beneficial bacteria and host tissues are unaffected, eliminating the broad-spectrum harmful effects associated with conventional antibiotic and steroid treatments while maintaining effective anti-inflammatory and antibacterial activity.

Inventive Principle:
Principle #3Local quality

3Reliability

If antibiotics are used to treat dermatitis, then bacterial infection can be controlled, but non-pathogenic and beneficial bacteria are killed and resistance develops

Engineering Contradiction:
Improveantibacterial effectVSAvoidkilling of beneficial bacteria
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The endolysin treatment exhibits highly specific local quality by targeting only bacteria with specific cell wall structures. This specificity allows selective elimination of pathogenic bacteria while preserving beneficial flora, as the enzymatic action is restricted to matching bacterial targets through structure-activity relationships of the phage-derived enzymes.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent converts the presence of pathogenic bacteria, which cause harm in dermatitis, into a beneficial therapeutic target. The bacteriophage endolysins are designed to specifically recognize and lyse these pathogenic bacteria, transforming the harmful bacterial population into the basis for selective eradication while sparing beneficial microbes that lack the appropriate cellular targets.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

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

The stabilization of endolysins with cereal meal significantly increases their stability and maintains lytic activity at higher temperatures, providing a more effective and safer treatment option for atopic dermatitis with reduced side effects.

Implementation Method 1

Endolysins lose their activity over time when in aqueous solutions. When bringing the protein in a lyophilized form, the inventors found that using oatmeal as a carrier, the stability of the endolysin surprisingly increased.
