Coenzyme Q10 (drug): This prospective study aims to evaluate the effect of 12 week CoQ10 supplementation (300 mg/day) on liver fat content (assessed by FibroTouch CAP) in MDM patients with m.3243A\>G mutation. An exploratory case control design will compare baseline characteristics among MDM patients, type 1 diabetes patients, and healthy controls.

Study summary
Mitochondrial diabetes mellitus (MDM) is a rare subtype of diabetes caused by mitochondrial dysfunction, often accompanied by hepatic steatosis. Coenzyme Q10 (CoQ10), a key electron carrier and antioxidant, may improve mitochondrial function and lipid metabolism. This prospective study aims to evaluate the effect of 12-week CoQ10 supplementation (300 mg/day) on liver fat content (assessed by FibroTouch CAP ) in MDM patients with m.3243A\>G mutation. An exploratory case-control design will compare baseline characteristics among MDM patients, type 1 diabetes patients, and healthy controls. This study is the first to explore the link between mitochondrial defects and hepatic fat accumulation specifically in MDM, and to test CoQ10 as a potential therapy, offering new insights for both MDM and MAFLD management.

Primary outcome measure(s)
Liver Fat Quantification — From enrollment to the end of treatment at 12 weeks The degree of hepatic fat deposition is assessed using the Controlled Attenuation Parameter (CAP) value measured by FibroTouch ultrasound imaging. The CAP value, expressed in dB/m, indicates the severity of hepatic steatosis, with higher values reflecting more advanced fat accumulation in the live.
