CoQ10 during dialysis: an oxidative-stress marker is not kidney recovery

A trial found a reduction in one oxidative-stress marker at its higher tested dose. It did not establish restored kidney function or improved survival.

What the study found

Eighty people on maintenance hemodialysis were randomized to two CoQ10 regimens or placebo for four months. Fifteen without a postbaseline visit were excluded, leaving 65 in the primary analysis. [1]

The higher tested regimen significantly reduced F2-isoprostanes relative to placebo; the lower regimen did not. Other oxidative and cardiac biomarkers and predialysis blood pressure did not significantly differ. [1]

What remains unanswered

The study was small and had baseline group differences. A laboratory marker is not direct evidence of kidney recovery, fewer cardiovascular events or freedom from dialysis. Funding and conflicts were not established from the abstract; high research doses are not personal instructions. [1]

A hypothetical distinction

Imagine a blood marker falls while the study does not measure recovery of organ function. Calling the result organ repair would add an outcome that was never demonstrated.
