Metabolic Effects of Medium-Chain Fatty Acids in Patients with Medium-Chain Acyl-CoA Dehydrogenase Deficiency and Healthy Individuals

Not Applicable

Recruiting

• Conditions: Medium-chain Acyl-CoA Dehydrogenase Deficiency
• Interventions: Other: Medium-Chain Fatty Acid (MCFA); Other: Long-Chain Fatty Acid (LCFA)

• Registration Number: NCT06623032
• Lead Sponsor: University of Copenhagen

Brief Summary

The aim of this project is to investigate the physiological effects of intake of long-chain fatty acids (LCFA) and medium-chain fatty acids (MCFA) in patients with Medium-Chain Acyl-CoA Dehydrogenase Deficiency (MCADD) and healthy individuals

Detailed Description

Male and female MCADD patients and healthy individuals will be included in this study which is a randomized intervention study in a cross over design consisting of two separate test days.

The study involves two test days of four hours each, during which the participants ingests either medium-chain fatty acids (MCFA) or long-chain fatty acids (LCFA) in the form of triacylglycerol oils. The order of fatty acid oils ingested is determined by randomization.
