Reported PML incidence rates among SLE patients based on observational studies ranged from 1.0 to 2.4 cases\/100,000 person-years. Of the 35 case reports, three cases were exposed to no immunosuppressant drugs at PML diagnosis, five cases had minimal immunosuppression, 23 cases had immunosuppression, and four cases were indeterminate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The evidence from this literature review suggests that, while PML is a very rare disease in SLE patients, there does appear to be an increased risk of PML associated with SLE compared to the general population, potentially due to immunosuppression, other contributing factors in their underlying disease, treatments prescribed to manage disease, or some combination of these factors. Additional large observational studies, designed to assess exposure to drugs of interest and complicated treatment histories, are needed to provide further evidence about potential mechanisms contributing to the onset of PML in SLE patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0961203315622819","type":"journal-article","created":{"date-parts":[[2016,1,7]],"date-time":"2016-01-07T20:07:48Z","timestamp":1452197268000},"page":"617-626","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":69,"title":["Progressive multifocal leukoencephalopathy in patients with systemic lupus erythematosus: a systematic literature review"],"prefix":"10.1177","volume":"25","author":[{"given":"C E","family":"Henegar","sequence":"first","affiliation":[{"name":"Worldwide Epidemiology, GlaxoSmithKline, Research Triangle Park, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A M","family":"Eudy","sequence":"additional","affiliation":[{"name":"Worldwide Epidemiology, GlaxoSmithKline, Research Triangle Park, USA"},{"name":"Gillings School of Global Public Health, The University of North Carolina at Chapel Hill, Chapel Hill, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V","family":"Kharat","sequence":"additional","affiliation":[{"name":"Worldwide Epidemiology, GlaxoSmithKline, Research Triangle Park, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D D","family":"Hill","sequence":"additional","affiliation":[{"name":"Worldwide Epidemiology, GlaxoSmithKline, Research Triangle Park, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D","family":"Bennett","sequence":"additional","affiliation":[{"name":"Worldwide Epidemiology, GlaxoSmithKline, Research Triangle Park, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Haight","sequence":"additional","affiliation":[{"name":"Global Clinical Safety and Pharmacovigilance, GlaxoSmithKline, Research Triangle Park, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,1,6]]},"reference":[{"key":"bibr1-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcv.2009.12.006"},{"key":"bibr2-0961203315622819","first-page":"2051","volume-title":"Principles and practices of infectious diseases","author":"Tan CS","year":"2009"},{"key":"bibr3-0961203315622819","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1093\/brain\/81.1.93","volume":"81","author":"Astrom KE","year":"1958","journal-title":"Brain"},{"key":"bibr4-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1086\/597126"},{"key":"bibr5-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.21277"},{"key":"bibr6-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.10450"},{"key":"bibr7-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1016\/B978-1-4160-4044-6.50171-0"},{"key":"bibr8-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1126\/science.1103492"},{"key":"bibr9-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1097\/00019052-200406000-00019"},{"key":"bibr10-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1086\/595299"},{"key":"bibr11-0961203315622819","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2012-201638"},{"key":"bibr12-0961203315622819","unstructured":"Coloma PM.\n                      Mining electronic healthcare record databases to augment drug safety surveillance\n                      .
