Abstract
Ethylmalonic acid (EMA) accumulates in tissues and biological fluids of patients affected by short-chain acyl-CoA dehydrogenase deficiency (SCADD) and ethylmalonic encephalopathy, illnesses characterized by neurological and muscular symptoms. Considering that the mechanisms responsible for the brain and skeletal muscle damage in these diseases are poorly known, in the present work we investigated the effects of acute EMA administration on redox status parameters in cerebral cortex and skeletal muscle from 30-day-old rats. Animals received three subcutaneous injections of EMA (6 μmol/g; 90 min interval between injections) and were killed 1 h after the last administration. Control animals received saline in the same volumes. EMA administration significantly increased thiobarbituric acid-reactive substances levels in cerebral cortex and skeletal muscle, indicating increased lipid peroxidation. In addition, carbonyl content was increased in EMA-treated animal skeletal muscle when compared to the saline group. EMA administration also significantly increased 2’,7’-dihydrodichlorofluorescein oxidation and superoxide production (reactive species markers), and decreased glutathione peroxidase activity in cerebral cortex, while glutathione levels were decreased only in skeletal muscle. On the other hand, respiratory chain complex I-III activity was altered by acute EMA administration neither in cerebral cortex nor in skeletal muscle. The present results show that acute EMA administration elicits oxidative stress in rat brain and skeletal muscle, suggesting that oxidative damage may be involved in the pathophysiology of the brain and muscle symptoms found in patients affected by SCADD and ethylmalonic encephalopathy.

Abstract
Ethylmalonic acid (EMA) accumulation occurs in various metabolic diseases with neurological manifestation, including short acyl-CoA dehydrogenase deficiency (SCADD) and ethylmalonic encephalopathy (EE). Since pathophysiological mechanisms responsible for brain damage in these disorders are still poorly understood, we investigated the ex vivo effects of acute intrastriatal administration of EMA on important parameters of energy and redox homeostasis in striatum from young rats. We evaluated CO(2) production from glucose, glucose utilization and lactate production, as well as the activities of the citric acid cycle (CAC) enzymes, the electron transfer chain (ETC) complexes II-IV (oxidative phosphorylation, OXPHOS) and synaptic Na(+),K(+)-ATPase. We also tested the effect of EMA on malondialdehyde (MDA) levels (marker of lipid oxidation) and reduced glutathione (GSH) levels. EMA significantly reduced CO(2) production, increased glucose utilization and lactate production, and reduced the activities of citrate synthase and of complexes II and II-III of the ETC, suggesting an impairment of CAC and OXPHOS. EMA injection also reduced Na(+),K(+)-ATPase activity and GSH concentrations, whereas MDA levels were increased. Furthermore, EMA-induced diminution of Na(+),K(+)-ATPase activity and reduction of GSH levels were prevented, respectively, by the antioxidants melatonin and N-acetylcysteine, indicating that reactive species were involved in these effects. Considering the importance of CAC and ETC for energy production and Na(+),K(+)-ATPase for the maintenance of the cell membrane potential, the present data indicate that EMA compromises mitochondrial homeostasis and neurotransmission in striatum. We presume that these pathomechanisms may be involved to a certain extent in the neurological damage found in patients affected by SCADD and EE.

Abstract
Predominant accumulation of ethylmalonic acid (EMA) in tissues and biological fluids is a characteristic of patients affected by short chain acyl-CoA dehydrogenase deficiency and ethylmalonic encephalopathy. Neurological abnormalities are frequently found in these disorders, but the mechanisms underlying the brain injury are still obscure. Since hyperlacticacidemia is also found in many affected patients indicating a mitochondrial dysfunction; in the present work, we evaluated the in vitro and ex vivo effects of EMA plus Ca(2+) on mitochondrial integrity and redox balance in succinate-supported brain organelles. We verified that the evaluated parameters were disturbed only when EMA was associated with exogenous micromolar Ca(2+) concentrations. Thus, we found that this short chain organic acid plus Ca(2+) dissipated the membrane potential and provoked mitochondrial swelling, as well as impaired the mitochondrial Ca(2+) retention capacity, resulting in a rapid Ca(2+) release and decreased NAD(P)H matrix content. In contrast, EMA was not able to stimulate mitochondrial hydrogen peroxide generation. We also observed that all these effects were prevented by the mitochondrial Ca(2+) uptake inhibitor ruthenium red and the mitochondrial permeability transition (MPT) inhibitors cyclosporin A (CsA) and ADP. Furthermore, mitochondria isolated from rat brains after in vivo intrastriatal administration of EMA was more susceptible to Ca(2+)-induced swelling, which was fully prevented by CsA and ADP. Finally, EMA significantly decreased striatal slice viability, which was attenuated by CsA. The data strongly indicate that EMA reduced the mitochondrial threshold for Ca(2+)-induced MPT reinforcing the role of this cation in EMA-induced disruption of mitochondrial bioenergetics. It is, therefore, presumed that EMA acting synergistically with Ca(2+) compromises mitochondrial energy homeostasis in the central nervous system that may explain at least in part the neurologic alterations presented by patients with abnormal levels of this organic acid.

Abstract
Ethylmalonic acid (EMA) accumulates in tissues of patients affected by short-chain acyl-CoA dehydrogenase deficiency and ethylmalonic encephalopathy, illnesses characterized by variable neurological symptoms. In this work, we investigated the in vitro and in vivo EMA effects on Na(+), K(+)-ATPase (NAK) activity and mRNA levels in cerebral cortex from 30-day-old rats. For in vitro studies, cerebral cortex homogenates were incubated in the presence of EMA at 0.5, 1, or 2.5 mM concentrations for 1 h. For in vivo experiments, animals received three subcutaneous EMA injections (6 μmol g(-1); 90-min interval) and were killed 60 min after the last injection. After that, NAK activity and its mRNA expression were measured. We observed that EMA did not affect this enzyme activity in vitro. In contrast, EMA administration significantly increased NAK activity and decreased mRNA NAK expression as assessed by semiquantitative reverse transcriptase polymerase chain reaction when compared with control group. Considering the high score of residues prone to phosphorylation on NAK, this profile can be associated with a possible regulation by specific phosphorylation sites of the enzyme. Altogether, the present results suggest that NAK alterations may be involved in the pathophysiology of brain damage found in patients in which EMA accumulates.

Abstract
Ethylmalonic encephalopathy (EE) is a rare metabolic disorder caused by dysfunction of ETHE1, a mitochondrial dioxygenase involved in hydrogen sulfide (H2S) detoxification. Patients present in infancy with psychomotor retardation, chronic diarrhea, orthostatic acrocyanosis and relapsing petechiae. High levels of lactic acid, ethymalonic acid (EMA) and methylsuccinic acid (MSA) are detected in body fluids. Several pathways may contribute to the pathophysiology, including isoleucine, methionine and fatty acid metabolism. We report on a 15-month-old male presenting with typical EE associated with a homozygous ETHE1 mutation. We investigated oral isoleucine (150 mg/kg), methionine (100 mg/kg), fatty acid loading tests and isoleucine-restricted diet (200 mg/day) for any effects on several metabolic parameters. Before loading tests or specific dietary interventions, EMA, C4-C5 acylcarnitines and most acylglycines were elevated, indicating functional deficiency of short chain acyl-CoA (SCAD) as well as all branched acyl-CoA dehydrogenases. Excretion of EMA and n-butyrylglycine increased following each of the loads, and isoleucine led to increased levels of derivative metabolites. An isoleucine-restricted diet for 8 days corrected some of the abnormalities but led to no obvious clinical improvement and only partial effects on EMA. A principal component analysis supports the inference that these dietary conditions have consistent effects on the global metabolic profile. Our results suggest that multiple pathways modulate EMA levels in EE. They might all interact with H2S toxicity. Prolonged dietary interventions involving the restriction for branched aminoacids, fatty acids and methionine could be discussed as auxiliary therapeutical strategies in EE.

Abstract
Our aim was to compare urinary ethylmalonic acid (EMA) levels in subjects who had no apparent clinical reason to have increased levels of this substance but were suffering from non-specific CNS impairment, and healthy controls. Urinary EMA concentrations detected by (1)H-NMR spectroscopy were studied in 130 subjects with CNS impairment of unknown origin (with no definite diagnosis, no specific symptoms or signs, and normal common biochemical and metabolic screening results) and 130 age- and sex-matched healthy subjects. EMA levels exceeding two standard deviations (SD) above normal (i.e. 8.1 mmol/molCn) were found in a subgroup of CNS-impaired patients and healthy controls. EMA levels exceeding 2 SD above normal were fourfold prevalent in the urine of patients with non-specific CNS impairment compared to from the EMA levels in healthy controls. Moreover, we found that the level exceeding > 8.1 mmol/molCn (i.e. > + 2 SD) had sufficient discrimination accuracy in identifying subjects with non-specific CNS impairment; the level exceeding 12 mmol/molCn (i.e. > + 6 SD) reaches suitable accuracy (i.e. 100% specificity and 78.6% sensitivity). These observations are of importance, as we found that subtle increases in urinary EMA levels are frequent in patients with non-specific CNS impairment. The reasons for this association remain unknown.
