Coenzyme Q10 administration has no effect on sICAM-1 and metabolic parameters of pediatrics with type 1 diabetes mellitus

Background: Endothelial dysfunction (ED) plays a key role in the development and progression of microvascular and macrovascular complications in pediatrics with type 1 diabetes mellitus (T1DM). Coenzyme Q10 (CoQ10) is a nutraceutical with a known anti-inflammatory and anti-oxidant activity. This study was conducted to evaluate the potential effect of CoQ10 on ED and various metabolic parameters. Methods: This prospective randomized open-label pilot study was conducted on 49 T1DM pediatric patients. Seven healthy non-diabetic pediatric subjects who didn't receive treatment were included as a control group. Eligible patients were randomly allocated into either group I (n = 25); received 100 mg of CoQ10 in addition to standard treatment or group II (n = 24); received standard treatment only. The levels of; soluble intracellular adhesion molecule-1 (sICAM-1), glycated hemoglobin (HbA1c), fasting blood glucose (FBG), lipid profile, serum creatinine and liver function tests were assessed for both groups at baseline and after 3 months of treatment. Results: At baseline, compared to an age-matched healthy control group sICAM-1 levels were significantly elevated in group II diabetic patients (276.5 (231.6-320.66) vs 221.8 (177.9-267.1 ng/ml), p = 0.042. After 3 months of treatment no significant difference was observed in sICAM-1, HbA1c, FBG, lipid profile, serum creatinine and liver function tests between the two study groups. A positive correlation was found between sICAM-1 and HbA1c throughout the study (r = 0.308, p = 0.0054). Conclusion: Administration of CoQ10 for 3 months in T1DM pediatric patients was well tolerated but had no favorable effect on ED or metabolic parameters.

Automated summary

The study found that administration of CoQ10 for 3 months in T1DM pediatric patients was well tolerated but had no favorable effect on endothelial dysfunction or metabolic parameters. There was a positive correlation between sICAM-1 and HbA1c throughout the study.
