The main cause of kidney injury is acute tubular necrosis from medications or myoglobinuria, though clinicians should be aware of a wide variety of possible aetiologies. We present the case of a 44-year-old woman with stable anti-Jo1 dermatomyositis, who presented with acute kidney injury. During her hospital course, she was diagnosed with double-positive disease characterised by circulating anti-glomerular basement membrane antibody and myeloperoxidase antineutrophil cytoplasmic antibody and renal biopsy revealing crescentic glomerulonephritis with linear staining of capillary wall for IgG.<\/jats:p>","DOI":"10.1136\/bcr-2018-224475","type":"journal-article","created":{"date-parts":[[2018,7,24]],"date-time":"2018-07-24T13:22:39Z","timestamp":1532438559000},"page":"bcr-2018-224475","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Double-positive with positive anti-glomerular basement membrane antibody and ANCA-positive disease in a patient with dermatomyositis"],"prefix":"10.1136","volume":"2018","author":[{"given":"Eric J","family":"Dein","sequence":"first","affiliation":[{"name":"Internal Medicine, Johns Hopkins Bayview Medical Center, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Crespo-Bosque","sequence":"additional","affiliation":[{"name":"Rheumatology, Johns Hopkins Hospital and Health System, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Homa","family":"Timlin","sequence":"additional","affiliation":[{"name":"Rheumatology, Johns Hopkins, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duvuru","family":"Geetha","sequence":"additional","affiliation":[{"name":"Nephrology, Johns Hopkins University, Baltimore, Maryland, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,7,24]]},"reference":[{"key":"2025082801493948000_2018.jul24_1.bcr-2018-224475.1","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1097\/MD.0000000000000015","article-title":"The spectrum of renal involvement in patients with inflammatory myopathies","volume":"93","author":"Couvrat-Desvergnes","year":"2014","journal-title":"Medicine"},{"key":"2025082801493948000_2018.jul24_1.bcr-2018-224475.2","doi-asserted-by":"crossref","unstructured":"Hellmark T , Segelmark M .
