A 59-year-old woman with a baseline creatinine of 0.7\u2009mg\/dL presented with rash on her legs, night sweats and weight loss for 3 weeks. Further evaluation revealed IE. Her blood cultures grew gamma-haemolytic streptococcus, which subsequently cleared on appropriate antibiotic therapy. Her creatinine, however, progressively worsened requiring haemodialysis. Kidney biopsy showed immune complex-mediated necrotising and crescentic GN. She was started on plasmapheresis (PE) and high-dose steroids with rapid taper, with subsequent improvement in her creatinine to 0.8\u2009mg\/dL. She subsequently had aortic valve replacement and ventricular septal defect closure. She did not improve as expected with antibiotic therapy but turned around dramatically with steroids and PE. Our case supports the possible beneficial role of PE and steroids in IE-related crescentic GN that worsens despite appropriate antibiotic therapy, although the risks of immunosuppression and aggravating endocarditis need to be considered.<\/jats:p>","DOI":"10.1136\/bcr-2018-227672","type":"journal-article","created":{"date-parts":[[2019,3,14]],"date-time":"2019-03-14T10:55:40Z","timestamp":1552560940000},"page":"e227672","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Plasmapheresis and corticosteroids in infective endocarditis-related crescentic glomerulonephritis"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3209-8140","authenticated-orcid":false,"given":"Kunal","family":"Malhotra","sequence":"first","affiliation":[{"name":"Division of Nephrology, University of Missouri School of Medicine, Columbia, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Preethi","family":"Yerram","sequence":"additional","affiliation":[{"name":"Division of Nephrology, University of Missouri School of Medicine, Columbia, Missouri, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,3,14]]},"reference":[{"key":"2025082711192821000_12.3.e227672.1","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/15.11.1782"},{"key":"2025082711192821000_12.3.e227672.2","doi-asserted-by":"crossref","first-page":"371","DOI":"10.1016\/S0272-6386(84)80086-4","article-title":"Glomerulonephritis in bacterial endocarditis","volume":"3","author":"Neugarten","year":"1984","journal-title":"Am J Kidney Dis"},{"key":"2025082711192821000_12.3.e227672.3","first-page":"352","article-title":"Crescentic glomerulonephritis associated with bacterial endocarditis--antibiotics alone may be sufficient.
