A critical incident during marathon competition as a result of metabolic decompensation

A case of polyorganic insufficiency syndrome associated with coma, convulsive disorder, acute hepato-renal and respiratory dysfunction, hypovolemic shock, and hyperthermal syndrome in a 46 year-old participant ofa marathon competition is reported. The clinical picture was dominated by acute hepatic insufficiency treated with remaxol to activate substrate phosphorylation under effect of exogenous succinate for slowing down the development of energy deficit in mitochondria under condition of oxygen deficit. This case can be regarded as a variant of correction of mitochondrial dysfunction with the use of a mitochondria-targeted medication such as succinate-containing remaxol. This medication reduced AST and ALT activities and utilization of endogenous enzymes for succinate synthesis from alanine and aspartate under hypoxic conditions. Prescription of remaxol as a form of direct substitution therapy was dictated by pathogenetic considerations.
