It often gets mistaken for rheumatoid arthritis or lupus but typically improves within four weeks when the medication is stopped. A 51-year-old man with Graves\u2019 disease developed a rash and disabling joint pain in multiple areas within weeks of starting methimazole. Labs showed elevated liver enzymes and CRP, but no autoimmune markers. Symptoms improved quickly after a short steroid taper and stopping the drug. This case shows how AAS can mimic autoimmune disease and why it is important to recognize early to avoid unnecessary treatment.<\/jats:p>","DOI":"10.55729\/2000-9666.1579","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T01:13:12Z","timestamp":1773882792000},"page":"65-67","source":"Crossref","is-referenced-by-count":1,"title":["Don\u2019t Mistake It for RA: A Case of Antithyroid Arthritis Syndrome After Methimazole Initiation"],"prefix":"10.55729","volume":"16","author":[{"given":"Michael K.","family":"Viggiano","sequence":"first","affiliation":[{"name":"Hackensack Meridian Health Palisades Medical Center Internal Medicine Department, 7600 River Rd, North Bergen, NJ 07047"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Auda","family":"Baker","sequence":"additional","affiliation":[{"name":"Hackensack Meridian Health Palisades Medical Center Internal Medicine Department, 7600 River Rd, North Bergen, NJ 07047"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Palanker","sequence":"additional","affiliation":[{"name":"Hackensack Meridian Health Palisades Medical Center Internal Medicine Department, 7600 River Rd, North Bergen, NJ 07047"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayrton","family":"Bangolo","sequence":"additional","affiliation":[{"name":"1.\tHackensack Meridian Health Palisades Medical Center Internal Medicine Department, 7600 River Rd, North Bergen, NJ 07047"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Belyayeva","sequence":"additional","affiliation":[{"name":"Hackensack Meridian Health Palisades Medical Center Internal Medicine Department, 7600 River Rd, North Bergen, NJ 07047"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iyad","family":"Baker","sequence":"additional","affiliation":[{"name":"Hackensack Meridian Health Palisades Medical Center Internal Medicine Department, 7600 River Rd, North Bergen, NJ 07047"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34701","published-online":{"date-parts":[[2026,3,17]]},"container-title":["Journal of Community Hospital Internal Medicine Perspectives"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T09:53:27Z","timestamp":1788602007000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.gbmc.org\/jchimp\/vol16\/iss2\/13"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,17]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2026,3,17]]}},"URL":"https:\/\/doi.org\/10.55729\/2000-9666.1579","relation":{},"ISSN":["2000-9666"],"issn-type":[{"value":"2000-9666","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,17]]}}}
