A Single Case Study of Hypermetabolism

Not Applicable

Completed

• Conditions: Hypermetabolism Due to Defect in Mitochondria; Luft Disease
• Interventions: Diagnostic Test: 18F FDG PET/CT

• Registration Number: NCT04805268
• Lead Sponsor: The Hospital for Sick Children

Brief Summary

In the Metabolic Disorder clinic at The Hospital for Sick Children, the investigators identified a male, proband with possible Luft's disease. The investigators hypothesize that Luft's disease is caused by excess or dysregulation of brown/beige fat tissue.

To address the hypothesis, the investigators would like to assess brown fat distribution and activity in this subject.

Detailed Description

The subject will undergo a fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F FDG PET/CT) at the Diagnostic Imaging unit of The Hospital for Sick Children.

Arm && Interventions

Group	Intervention	Description
One subject with possible Luft's disease	18F FDG PET/CT	18F-FDG will be administered I.V., approximately 1 hour prior to PET/CT scan.

Primary Outcome Measures

Name	Time	Method
Brown/beige fat tissue distribution and activity. Measurement tool- 18F FDG PET/CT (fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography)	1 day	Areas of 18F-FDG uptake on PET colocalizing with regions of fat will be identified on CT (-250to -10 Hounsfield Units) and quantified by Standard Uptake Value (SUV).
