An 81-year-old man was sent to nephrologist because of significantly increased creatinine (1.5\u20131.9\u2009mg\/dL) noted for 3 months. He had well-controlled diabetes but no history of kidney disease. He had no chronic diarrhoea or intestinal surgery. He was a health-minded individual who had read extensively about benefit of antioxidants. Initial work-up was unrevealing. Within a few weeks after first visit, he developed acute symptomatic worsening kidney injury with nausea, vomiting and creatinine up to 6.8\u2009mg\/dL. Repeat examination of the urine sediment revealed casts containing calcium oxalate crystals. A deeper dietary history revealed widespread oxalate precursor consumption. A kidney biopsy confirmed oxalate nephropathy. Restriction of oxalate consumption combined with adequate hydration, oral calcium acetate resulted in partial renal recovery without need for haemodialysis.<\/jats:p>","DOI":"10.1136\/bcr-2019-231284","type":"journal-article","created":{"date-parts":[[2019,9,16]],"date-time":"2019-09-16T21:07:24Z","timestamp":1568668044000},"page":"e231284","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":16,"title":["Diet-induced oxalate nephropathy"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6696-1424","authenticated-orcid":false,"given":"Barbara","family":"Clark","sequence":"first","affiliation":[{"name":"Medicine, Allegheny Health Network, Pittsburgh, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad Wisam","family":"Baqdunes","sequence":"additional","affiliation":[{"name":"Medicine, Allegheny Health Network, Pittsburgh, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory M","family":"Kunkel","sequence":"additional","affiliation":[{"name":"School of Medicine, Drexel University, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,9,16]]},"reference":[{"key":"2025082723555818000_12.9.e231284.1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.4061\/2011\/146927","article-title":"Vitamin C-induced oxalate nephropathy","volume":"2011","author":"Lamarche","year":"2011","journal-title":"Int J Nephrol"},{"key":"2025082723555818000_12.9.e231284.2","first-page":"593","article-title":"Primary hyperoxaluria type I","volume":"87","author":"Watts","year":"1994","journal-title":"QJM"},{"key":"2025082723555818000_12.9.e231284.3","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(05)82207-3"},{"key":"2025082723555818000_12.9.e231284.4","doi-asserted-by":"crossref","first-page":"430","DOI":"10.5414\/CNP71430","article-title":"An unusual complication of treatment with orlistat","volume":"71","author":"Karamadoukis","year":"2009","journal-title":"Clin Nephrol"},{"key":"2025082723555818000_12.9.e231284.5","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2006.10.004"},{"key":"2025082723555818000_12.9.e231284.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.soard.2005.07.002"},{"key":"2025082723555818000_12.9.e231284.7","doi-asserted-by":"crossref","first-page":"2320","DOI":"10.1681\/ASN.V7112320","article-title":"Secondary oxalosis: a cause of delayed recovery of renal function in the setting of acute renal failure","volume":"7","author":"Alkhunaizi","year":"1996","journal-title":"J Am Soc Nephrol"},{"key":"2025082723555818000_12.9.e231284.8","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.151327"},{"key":"2025082723555818000_12.9.e231284.9","doi-asserted-by":"crossref","first-page":"354","DOI":"10.5414\/CN109118","article-title":"Oxalate nephropathy following vitamin C intake within intensive care unit","volume":"88","author":"Colliou","year":"2017","journal-title":"Clin Nephrol"},{"key":"2025082723555818000_12.9.e231284.10","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1053\/j.ajkd.2017.08.002","article-title":"\u201cGreen Smoothie Cleanse\u201d\u00a0causing acute oxalate nephropathy","volume":"71","author":"Makkapati","year":"2018","journal-title":"Am J Kidney Dis"},{"key":"2025082723555818000_12.9.e231284.11","doi-asserted-by":"crossref","first-page":"109","DOI":"10.1016\/j.krcp.2014.03.003","article-title":"Peanut-induced acute oxalate nephropathy with acute kidney injury","volume":"33","author":"Park","year":"2014","journal-title":"Kidney Res Clin Pract"},{"key":"2025082723555818000_12.9.e231284.12","doi-asserted-by":"publisher","DOI":"10.1016\/S1521-6918(03)00108-2"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-231284","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T06:56:04Z","timestamp":1756364164000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-231284"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9]]},"references-count":12,"journal-issue":{"issue":"9","published-online":{"date-parts":[[2019,9,16]]},"published-print":{"date-parts":[[2019,9]]}},"alternative-id":["10.1136\/bcr-2019-231284"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-231284","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,9]]}}}
