Study participants underwent two assessments at least 9 months apart including clinical, laboratory and NVC evaluations. Patients received immunosuppressive medications for their dermatomyositis, and ongoing disease activity was measured by the Myositis Intention to Treat Index (MITAX). NVC evaluation included assessment of capillary density, capillary apical diameter (mm), and the number of microhemorrhages per digit.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Microvascular abnormalities were present in most DM patients. Of these, capillary density (4.71 vs. 6.84,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.006) and mean apical diameter (56.09 vs. 27.79 \u03bcm,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.003) significantly improved over the study period in concordance with improving disease control (MITAX 8.53 vs. 2.64,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.002). Longitudinal analysis demonstrated that capillary density was independently associated with MITAX (\u03b2 = \u22121.49 [CI \u22122.49, \u22120.33],\n                    <jats:italic>p<\/jats:italic>\n                    = 0.013), but not other parameters such as C-reactive protein and creatinine kinase.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Nailfold capillary density is a dynamic marker of global disease activity in adult DM. NVC may be utilized as a non-invasive point-of-care tool to monitor disease activity and inform treatment decisions in patients with DM.\n                  <\/jats:p>","DOI":"10.3389\/fmed.2021.708432","type":"journal-article","created":{"date-parts":[[2021,8,10]],"date-time":"2021-08-10T01:45:02Z","timestamp":1628559902000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":25,"title":["Nailfold Capillaroscopy Abnormalities Correlate With Disease Activity in Adult Dermatomyositis"],"prefix":"10.3389","volume":"8","author":[{"given":"Dylan","family":"Johnson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charmaine","family":"van Eeden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naima","family":"Moazab","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Desiree","family":"Redmond","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecile","family":"Phan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie","family":"Keeling","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Gniadecki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan Willem","family":"Cohen Tervaert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Osman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,8,10]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"303","DOI":"10.1038\/nrrheum.2018.33","article-title":"Update on outcome assessment in myositis","volume":"14","author":"Rider","year":"2018","journal-title":"Nat Rev Rheumatol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"782","DOI":"10.1136\/annrheumdis-2017-211401","article-title":"2016 American college of rheumatology\/European league against rheumatism criteria for minimal, moderate, and major clinical response in juvenile dermatomyositis","volume":"76","author":"Rider","year":"2017","journal-title":"Ann Rheum Dis"},{"key":"B3","doi-asserted-by":"publisher","first-page":"578","DOI":"10.1038\/nrrheum.2010.104","article-title":"Assessing microvascular changes in systemic sclerosis diagnosis and management","volume":"6","author":"Cutolo","year":"2010","journal-title":"Nat Rev Rheumatol."},{"key":"B4","doi-asserted-by":"publisher","first-page":"e000507","DOI":"10.1136\/rmdopen-2017-000507","article-title":"EULAR\/ACR classification criteria for adult and juvenile idiopathic inflammatory myopathies and their major subgroups: a methodology report","volume":"3","author":"Bottai","year":"2017","journal-title":"RMD Open."},{"key":"B5","doi-asserted-by":"publisher","first-page":"885","DOI":"10.1136\/ard.2007.079756","article-title":"Scoring the nailfold microvascular changes during the capillaroscopic analysis in systemic sclerosis patients","volume":"67","author":"Sulli","year":"2008","journal-title":"Ann Rheum Dis."},{"key":"B6","doi-asserted-by":"publisher","first-page":"237","DOI":"10.1016\/j.berh.2013.03.001","article-title":"How to perform and interpret capillaroscopy","volume":"27","author":"Cutolo","year":"2013","journal-title":"Best Pract Res Clin Rheumatol."},{"key":"B7","doi-asserted-by":"publisher","first-page":"49","DOI":"10.1093\/rheumatology\/keg427","article-title":"International consensus outcome measures for patients with idiopathic inflammatory myopathies.
