The oedema decreased spontaneously over weeks and there was no evidence for a nephrotic syndrome; however, the blood tests revealed a moderate pancytopenia. The patient practiced excessive physical activity at work and in his spare time, and kept a very thorough training and weight diary. Owing to a high intake of energy and protein drinks he tried to optimise his physical performance and kept a normal body mass index \u00a0at 23.7. A bone marrow biopsy showed gelatinous bone marrow transformation, normally seen in critically ill patients or those with severe malnutrition. In this case, the cause is presumed to be excessive physical activity\/overtraining in combination with relatively insufficient nutrition.<\/jats:p>","DOI":"10.1136\/bcr-2013-009210","type":"journal-article","created":{"date-parts":[[2013,6,28]],"date-time":"2013-06-28T11:42:19Z","timestamp":1372419739000},"page":"bcr2013009210","source":"Crossref","is-referenced-by-count":1,"title":["How to exhaust your bone marrow"],"prefix":"10.1136","volume":"2013","author":[{"given":"Louise","family":"Salomo","sequence":"first","affiliation":[{"name":"Department of Nephrology, University of Copenhagen, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Morten","family":"Salomo","sequence":"additional","affiliation":[{"name":"Department of Haematology, University of Copenhagen, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven A W","family":"Andersen","sequence":"additional","affiliation":[{"name":"Department of Haematology, University of Copenhagen, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne-Lise","family":"Kamper","sequence":"additional","affiliation":[{"name":"Department of Nephrology, University of Copenhagen, Rigshospitalet, Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,6,21]]},"reference":[{"key":"2025082704110243000_2013.jun21_1.bcr2013009210.1","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1097\/00000478-200001000-00007","article-title":"Gelatinous transformation of the bone marrow: the spectrum of underlying diseases","volume":"2013","author":"Bohm","year":"2000","journal-title":"Am J Surg Pathol"},{"key":"2025082704110243000_2013.jun21_1.bcr2013009210.2","doi-asserted-by":"crossref","first-page":"864","DOI":"10.1097\/PEC.0b013e3181f9dcd1","article-title":"Exertional rhabdomyolysis\u2014when should we start worrying?
