Solution Overview

Problem

Current methods for diagnosing diabetes mellitus, particularly type II, face challenges due to the instability of adrenomedullin, making reliable plasma-based diagnoses unreliable, and existing methods do not effectively utilize midregional proAdrenomedullin (MR-proADM) for diabetes diagnosis.

Innovation Solution

A method for in-vitro diagnosis and risk stratification of diabetes mellitus using midregional proAdrenomedullin (MR-proADM) or its partial peptides, combined with other markers, to determine the severity and complications of diabetes, employing techniques like immunoassays and lateral-flow tests for rapid and accurate assessments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adrenomedullin is used as a diagnostic marker for diabetes mellitus, then the diagnosis can be made based on the known relationship with diabetic microangiopathy, but the short duration and instability of adrenomedullin in plasma make reliable diagnosis impossible

Engineering Contradiction:
Improvediagnostic reliabilityVSAvoidplasma half-life of adrenomedullin
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent segments the adrenomedullin protein into different parts: the unstable N-terminal region and the stable C-terminal region (MR-proADM). By measuring only the stable C-terminal fragment, the patent achieves reliable diagnosis while avoiding the instability problem of the full adrenomedullin molecule.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and measures only the stable midregional proAdrenomedullin (MR-proADM) fragment from the complete adrenomedullin structure. This extraction of the stable fragment allows for reliable plasma-based diagnosis without being affected by the short half-life of the complete adrenomedullin molecule.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If existing proAdrenomedullin determination methods are used, then sepsis diagnosis is improved, but the suitability for diabetes mellitus diagnosis is not established and requires further validation

Engineering Contradiction:
Improvediagnostic suitability for diabetesVSAvoidvalidation and adaptation requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the universal diagnostic approach by using MR-proADM for multiple indications including both sepsis and diabetes mellitus. The same stable fragment and measurement methodology serve different diagnostic purposes, reducing the need for separate validation systems while establishing reliability across different disease contexts.

Inventive Principle:
Principle #6Universality (Multi-functionality)
