{"title":"Atypical myopathy associated with box elder in Europe","authors":"E. J. Knowles,&nbsp;R. J. Piercy","doi":"10.1111/eve.14117","DOIUrl":"10.1111/eve.14117","url":null,"abstract":"&lt;p&gt;The case report by Jahn et al. (&lt;span&gt;2025&lt;/span&gt;) describes a case of atypical myopathy in Europe caused by ingestion of the protoxin hypoglycin A (HGA) from box elder seedlings. This is an important report. It reminds clinicians in Europe that trees other than The European sycamore (&lt;i&gt;Acer pseudoplatanus&lt;/i&gt;) may contain HGA and that there is a potential for other unfamiliar plant species to cause pasture-associated toxicities.&lt;/p&gt;&lt;p&gt;After many years of research, the pathogenesis of atypical myopathy, also known as seasonal pasture myopathy, is now well understood. The severe myopathy results from the ingestion of the seeds or seedlings of European sycamore (&lt;i&gt;Acer pseudoplatanus&lt;/i&gt;) in Europe and the box elder (&lt;i&gt;Acer negundo&lt;/i&gt;) in the USA (Valberg et al., &lt;span&gt;2013&lt;/span&gt;; Westermann et al., &lt;span&gt;2008&lt;/span&gt;). The seeds, seedlings, and leaves of these trees contain the protoxin HGA, and to a lesser extent its analogue methylenecyclopropylglycine (MCPrG; Bochnia et al., &lt;span&gt;2019&lt;/span&gt;). These protoxins are metabolised to the active toxins methylenecyclopropylacetyl-CoA (MCPA-CoA) and MCPrG-CoA, respectively, at tissue-specific rates and primarily in skeletal muscle (Sander et al., &lt;span&gt;2023&lt;/span&gt;). The toxic effects mainly occur in the highly-oxidative ‘slow-twitch’ type I muscle fibres such as the postural muscles, masseters, diaphragm and cardiac muscle (Cassart et al., &lt;span&gt;2007&lt;/span&gt;). The primary toxin, MCPA-CoA inhibits acyl-CoA dehydrogenase enzymes involved in the beta-oxidation of fatty acids and catabolism of branched-chain amino acids resulting in failure of mitochondrial energy generation and subsequently muscle cell death (Westermann et al., &lt;span&gt;2008&lt;/span&gt;). Inhibition of Acyl-CoA dehydrogenase enzymes causes an accumulation of their acyl-CoA substrates and the carnitine and glycine conjugates of those substrates in serum and urine, a characteristic metabolic profile known as multiple acyl-CoA dehydrogenase deficiency (MADD) (Westermann et al., &lt;span&gt;2008&lt;/span&gt;). The accumulation of acylcarnitines together with the protoxins (HGA and MCPrG) and the carnitine conjugates of the toxins (MCPA-carnitine and MCPF-carnitine) can be detected in serum by liquid-chromatography-mass-spectometry (LCMS) (Bochnia et al., &lt;span&gt;2019&lt;/span&gt;; González-Medina et al., &lt;span&gt;2021&lt;/span&gt;; Valberg et al., &lt;span&gt;2013&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;In many cases a diagnosis of atypical myopathy can be made relatively confidently based on the characteristic clinical signs, serum biochemical changes, the seasonal occurrence and, in Europe, the presence of sycamore (&lt;i&gt;Acer psuedoplatanus&lt;/i&gt;) seeds or seedlings on the pasture (Dunkel et al., &lt;span&gt;2018&lt;/span&gt;; González-Medina et al., &lt;span&gt;2017&lt;/span&gt;). Detection of serum HGA or MCPA-carnitine by LCMS may be useful to confirm the diagnosis and may be particularly useful to identify sub-clinically affected cases, or those with less-severe or unusual presentations or when a toxic (tree) source cannot r","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"37 5","pages":"231-233"},"PeriodicalIF":0.8,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eve.14117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
