CBmeter study: protocol for assessing the predictive value of peripheral chemoreceptor overactivation for metabolic...

Area of Science:

• Metabolic disease research
• Cardiovascular and respiratory physiology
• Biomedical engineering

Background:

• Early screening for metabolic diseases reduces healthcare burdens.
• Overactivated carotid bodies (CB) are linked to type 2 diabetes.
• Non-invasive assessment of CB activity could predict metabolic diseases, but no devices currently exist.

Purpose of the Study:

• To clarify the role of CBs in metabolic disease development.
• To guide the creation of new therapeutic strategies for early intervention.
• To potentially aid in patient classification for future CB modulatory treatments.

Main Methods:

• A non-randomized, multicentric, controlled clinical study involving 40 participants (20 control, 20 diabetic).
• Establishing a novel early diagnosis model for metabolic diseases.
• Utilizing respiratory and metabolic responses to 100% oxygen and a mixed meal challenge.

Main Results:

• Data from the CBmeter will be validated against gold standards for vital signs and glucose levels.
• Multivariate analysis using specialized software (CBview) will be performed.
• Clustering analysis and AI-based unsupervised learning will determine predictive value for diabetes.

Conclusions:

• The CBmeter study aims to validate a new diagnostic approach for metabolic diseases.
• Findings may lead to improved early detection and intervention strategies.
• Results could inform future therapeutic interventions targeting CB activity.
