Advances in Management of Mitochondrial Myopathies
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This review discusses mitochondrial myopathies, genetic disorders arising from mutations in mitochondrial or nuclear DNA, in human patients. It covers pathophysiology, genetics, and clinical features, focusing on treatment and management. The authors state that no particular treatment currently exists, and that management guidelines are based on expert opinion, with therapies largely aimed at symptom relief and quality of life, commonly involving vitamins and cofactors, though the authors note evidence for their benefit is still lacking. The review states that elamipretide has shown promising results in earlier studies, with phase III trials still ongoing, and calls for a multidisciplinary management approach and further clinical trials of existing and novel experimental therapies.
Abstract
Mitochondria, the energy factories of human organisms, can be the cause of a variety of genetic disorders called mitochondrial myopathies. Mitochondrial diseases arise from genetic alterations in either mitochondrial DNA (mtDNA) or nuclear DNA (nDNA) and can manifest with great heterogeneity, leading to multiorgan dysfunction. The purpose of this article is to concisely review the pathophysiology, genetics and main clinical features of mitochondrial myopathies, focusing mainly on the treatment and management of these disorders. Currently, a particular treatment for mitochondrial myopathies does not exist, while the available guidelines concerning management are based on experts' opinions. The therapeutic options currently applied largely aim at symptom relief and amelioration of patients' quality of life. The most commonly used regimens involve the administration of vitamins and cofactors, although hard evidence regarding their true benefit for patients is still lacking. Recent studies have demonstrated promising results for elamipretide; however, phase III clinical trials are still ongoing. Regarding patient management, a multidisciplinary approach with the collaboration of different specialties is required. Further clinical trials for the already applied treatment options, as well as on novel experimental therapies, are of utmost importance in order to improve patients' outcomes.
