Acne Diagnosis via P. acnes Ribotype Sequencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current acne treatments lack personalization and are not targeted at specific bacteria causing acne, leading to ineffective treatments and side effects, with no method to diagnose dominant bacterial strains at the time of diagnosis.
Innovation Solution
A method involving skin sample analysis to isolate bacterial DNA, amplify 16S ribosomal DNA, sequence, and type based on major ribotypes or microbiome types of P. acnes strains to diagnose acne and develop personalized treatments using vaccines, probiotics, or phage therapy targeting specific strains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional acne treatments are used, then acne symptoms may be reduced, but the treatments lack personalization and target specific bacteria, leading to ineffective treatments and side effects
Solution Approach 1:
The patent segments the acne treatment approach by first identifying and classifying specific P. acnes bacterial strains present in the patient's skin, then selecting targeted therapies (antibiotics, retinoids, or cosmetic procedures) based on the identified strain characteristics. This segmentation enables personalized treatment rather than applying a single conventional treatment to all patients.
Solution Approach 2:
The patent changes the treatment parameters by using molecular typing methods (such as 16S rRNA sequencing or PCR-based fingerprinting) to identify bacterial strain characteristics, then adjusting treatment selection based on these identified parameters. This allows the treatment approach to be customized to the specific bacterial profile of each patient.
2Adaptability or versatility
If molecular typing methods are implemented to identify specific bacterial strains, then personalized treatment can be achieved, but the diagnostic process becomes more complex and time-consuming
Solution Approach 1:
The patent replaces complex traditional culture-based diagnostic methods with molecular typing techniques such as PCR-based fingerprinting or 16S rRNA sequencing. These molecular methods provide more precise bacterial identification while streamlining the diagnostic process compared to conventional prolonged culture methods.
Solution Approach 2:
The patent uses molecular copying techniques (PCR amplification of bacterial DNA) to rapidly generate sufficient genetic material for typing and identification. This allows quick replication and analysis of bacterial genetic markers without requiring lengthy culture growth periods.
3Measurement precision
If comprehensive bacterial strain identification is performed, then accurate personalized treatment can be developed, but the time required for diagnosis increases
Solution Approach 1:
The patent performs preliminary molecular typing analyses (such as preparing DNA extracts or setting up PCR reactions) that can be completed rapidly, providing sufficient bacterial identification data for treatment decisions without requiring extended diagnostic periods. This preliminary action enables timely personalized treatment planning.
Solution Approach 2:
The patent substitutes time-consuming traditional bacterial culture methods with faster molecular identification techniques such as PCR-based fingerprinting or sequencing, which can identify bacterial strains in hours rather than days, thereby maintaining high identification accuracy while significantly reducing diagnosis time.

AI summary
Methods of diagnosing and treating patients afflicted with acne, including diagnosing one as having acne if the individual possesses RT4, RT5, RT7, RT8, RT9, or RT10. Methods for treating acne include administering an effective amount of a drug specifically targeting RT4, RT5, RT7, RT8, RT9, or RT10, such as small molecules, antisense molecules, siRNAs, biologics, antibodies, phages, vaccines, or combination thereof.
