Perspective targeted diagnosis and therapy of mitochondrial bioenergetics across different diagnoses

Important metabolic variables that lead to the development of many diseases, including "mitochondrial diseases," include increased oxidative stress and mitochondrial malfunction. Given that the clinical picture and metabolic alterations in individuals suspected of having mitochondrial illnesses lack distinct characteristics, the development of sensitive and specific diagnostic techniques to detect alterations in mitochondrial bioenergetics is imperative. High-resolution respirometry (HRR), is a minimally invasive technique that enables the analysis of mitochondrial function in platelets taken from peripheral blood. This method allows for the detection of even the most subtle changes prior to disease development. HRR can identify minute variations in mitochondrial bioenergetics. Determining mitochondrial function and endogenous levels of CoQ10 in platelets can aid in the early detection of pathobiochemical changes in mitochondria and assessment of treatment efficacy. When combined with the measurement of endogenous coenzyme Q10 levels, HRR may be an effective approach for early identification of compromised mitochondrial function along with monitoring the therapeutic outcomes. Supplementing with coenzyme Q10, applying molecular hydrogen, transplanting mitochondria, and applying platelet-rich plasma (PRP) are some of the therapeutic strategies utilized to enhance mitochondrial function and reduce oxidative stress (Tab. 1, Fig. 1, Ref. 62).
