Clinic records of all AVN cases diagnosed up to July 2009 in HIV-positive patients attending North Middlesex Hospital, London, UK were retrospectively reviewed. For each case, one control was randomly selected, matched for gender, age, nadir CD4 count and date of HIV diagnosis. Of 15 symptomatic AVN cases identified, eight were in women. Univariate analysis demonstrated significant associations between AVN and a history of systemic steroid use ( p\u2009=\u20090.004) and cumulative exposure to protease inhibitor ( p\u2009=\u20090.03). Physicians should be aware of the risk of AVN with steroid use, the importance of early diagnosis and avoidance of other risk factors in order to prevent further joint involvement if possible.<\/jats:p>","DOI":"10.1177\/0956462413482814","type":"journal-article","created":{"date-parts":[[2013,7,10]],"date-time":"2013-07-10T21:39:40Z","timestamp":1373492380000},"page":"799-803","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Avascular necrosis in HIV patients: a case\u2013control study"],"prefix":"10.1177","volume":"24","author":[{"given":"GG","family":"Whitlock","sequence":"first","affiliation":[{"name":"Centre for Sexual Health & HIV Research, Research Department of Infection and Population Health, University College London, London, UK"},{"name":"North Middlesex University Hospital NHS Trust, Sterling Way, London, UK"},{"name":"The Mortimer Market Centre, Central and North West London NHS Foundation Trust, Mortimer Market, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Herbert","sequence":"additional","affiliation":[{"name":"North Middlesex University Hospital NHS Trust, Sterling Way, London, UK"},{"name":"The Mortimer Market Centre, Central and North West London NHS Foundation Trust, Mortimer Market, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Copas","sequence":"additional","affiliation":[{"name":"Centre for Sexual Health & HIV Research, Research Department of Infection and Population Health, University College London, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Gilson","sequence":"additional","affiliation":[{"name":"Centre for Sexual Health & HIV Research, Research Department of Infection and Population Health, University College London, London, UK"},{"name":"The Mortimer Market Centre, Central and North West London NHS Foundation Trust, Mortimer Market, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JG","family":"Ainsworth","sequence":"additional","affiliation":[{"name":"North Middlesex University Hospital NHS Trust, Sterling Way, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,7,10]]},"reference":[{"issue":"2","key":"bibr1-0956462413482814","first-page":"87","volume":"13","author":"Williams I","year":"2012","journal-title":"HIV Med"},{"key":"bibr2-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1001\/jama.296.7.844"},{"key":"bibr3-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1086\/319745"},{"key":"bibr4-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1086\/428837"},{"key":"bibr5-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/41.10.1200"},{"key":"bibr6-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1177\/1076029607310217"},{"key":"bibr7-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1590\/S1413-86702007000100009"},{"key":"bibr8-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1089\/aid.2004.20.909"},{"key":"bibr9-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1086\/322779"},{"key":"bibr10-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1097\/00126334-200009010-00003"},{"key":"bibr11-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1007\/s00774-010-0245-5"},{"key":"bibr12-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijantimicag.2003.05.006"},{"key":"bibr13-0956462413482814","doi-asserted-by":"publisher","DOI":"10.1097\/QAD.0b013e32834af637"},{"key":"bibr14-0956462413482814","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-137-1-200207020-00008"},{"key":"bibr15-0956462413482814","doi-asserted-by":"crossref","unstructured":"Mehta P, Nelson M, Brand A, et\u00a0al.
