McArdle disease is a common metabolic defect caused by an inherited deficit of myophosphorylase. These 2 diseases might have some clinical heterogeneity. Here, we discuss a McArdle disease case where insulin-dependent diabetes overshadows its early diagnosis. In this case, an insulin-dependent 22-year-old female patient with diabetes mellitus had been on diabetes treatment for 15\u2009years. Although her blood glucose was regulated, her anamnesis showed that muscle weakness, fatigue, cramps or myalgia never healed. Based on her anamnesis, the patient was asked to take a nonischemic forearm exercise test, which revealed significant elevation in levels of creatine kinase (5968-7906 U\/L), but no increase was found in lactate concentration, but a slight increase in ammonia concentration (not statistically significant) at the end of the test made us consider McArdle disease. A genetic test was done to confirm this possibility. A homozygous c.2128_2130delTTC\/p.Phe710del mutation was detected in the examination of exons of the PYGM gene, which confirmed the diagnosis of McArdle disease in our patient. According to the data, this is a rare case of McArdle disease with type 1 diabetes. During treatment for diabetes, if the above-mentioned symptoms are present in a patient, and especially if the patient\u2019s creatine kinase concentration is high, muscle diseases should be suspected. Therefore, we suggest that this case report will provide new insight to clinicians on metabolic defects in this disease and increase the patient comfort. In such cases, an early diagnosis should reduce health costs. <\/jats:p>","DOI":"10.1177\/1178626419861407","type":"journal-article","created":{"date-parts":[[2019,7,15]],"date-time":"2019-07-15T07:53:31Z","timestamp":1563177211000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A High Creatine Kinase Concentration Might Be a Sign of McArdle Disease in Patient With Type 1 Diabetes"],"prefix":"10.1177","volume":"12","author":[{"given":"Kader","family":"Ugur","sequence":"first","affiliation":[{"name":"Department of Internal Medicine (Endocrinology and Metabolism Diseases), School of Medicine, Firat University, Elazig, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yakup","family":"Aydogan","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine (Endocrinology and Metabolism Diseases), School of Medicine, Firat University, Elazig, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdurrahman","family":"Akgun","sequence":"additional","affiliation":[{"name":"Department of Pediatric (Metabolism Diseases), School of Medicine, Firat University, Elazig, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suleyman","family":"Aydin","sequence":"additional","affiliation":[{"name":"Department of Medical Biochemistry and Clinical Biochemistry (Firat Hormones Research Group), Medical School, Firat University, Elazig, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,7,15]]},"reference":[{"key":"bibr1-1178626419861407","doi-asserted-by":"publisher","DOI":"10.1530\/JOE-18-0120"},{"key":"bibr2-1178626419861407","first-page":"53","volume":"26","author":"Andreu AL","year":"2007","journal-title":"Acta Myol"},{"key":"bibr3-1178626419861407","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-006-0447-x"},{"key":"bibr4-1178626419861407","doi-asserted-by":"crossref","first-page":"82","DOI":"10.5606\/tftrd.2017.89083","volume":"63","author":"\u00c7ak\u0131r T","year":"2017","journal-title":"Turk J Phys Med Rehab"},{"key":"bibr5-1178626419861407","doi-asserted-by":"publisher","DOI":"10.1055\/s-0028-1093525"},{"key":"bibr6-1178626419861407","doi-asserted-by":"publisher","DOI":"10.1080\/01616412.2016.1243638"},{"key":"bibr7-1178626419861407","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa031836"}],"container-title":["Biochemistry Insights"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1178626419861407","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1178626419861407","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1178626419861407","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,10,4]],"date-time":"2024-10-04T06:39:24Z","timestamp":1728023964000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1178626419861407"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1]]},"references-count":7,"alternative-id":["10.1177\/1178626419861407"],"URL":"https:\/\/doi.org\/10.1177\/1178626419861407","relation":{},"ISSN":["1178-6264","1178-6264"],"issn-type":[{"type":"print","value":"1178-6264"},{"type":"electronic","value":"1178-6264"}],"subject":[],"published":{"date-parts":[[2019,1]]},"article-number":"1178626419861407"}}
