Patients have elevated plasma phytanic acid levels and high concentrations of phytanic acid in a variety of tissues leading to progressive tissue damage. Besides retinal degeneration or retinal dystrophy associated with adult onset retinitis pigmentosa, additional symptoms include chronic polyneuropathy, cerebellar ataxia, sensorineural hearing loss, anosmia, ichthyosis, as well as skeletal, cardiac, hepatic, and renal abnormalities. Current management includes avoidance of dietary sources of branched chain fatty acids and regular plasmapheresis to prevent accumulation of these compounds to ameliorate progressive neurological deficits. Two brothers with Refsum's disease who experienced progressive symptoms despite optimal diet and plasmapheresis were commenced on a novel therapy. We report the effect of the intestinal lipase inhibitor, Orlistat, which led to significant reduction (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mi>P<\/mml:mi><mml:mtext>-<\/mml:mtext><\/mml:math>value<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\"><mml:mo>&lt;<\/mml:mo><mml:mn>0.001<\/mml:mn><\/mml:math>on 2-sample unpaired<jats:italic>t<\/jats:italic>-test) of mean preplasmapheresis phytanic acid levels with retardation of the progression of most of their dermatological and neurological symptoms.<\/jats:p>","DOI":"10.1155\/2011\/482021","type":"journal-article","created":{"date-parts":[[2010,9,1]],"date-time":"2010-09-01T18:34:43Z","timestamp":1283366083000},"page":"1-5","source":"Crossref","is-referenced-by-count":5,"title":["Refsum's Disease\u2014Use of the Intestinal Lipase Inhibitor, Orlistat, as a Novel Therapeutic Approach to a Complex Disorder"],"prefix":"10.1155","volume":"2011","author":[{"given":"Nimalie J.","family":"Perera","sequence":"first","affiliation":[{"name":"Department of Clinical Biochemistry, Royal Prince Alfred Hospital, Sydney, Camperdown, NSW 2050, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barry","family":"Lewis","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Sydney, NSW 2006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huy","family":"Tran","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, John Hunter Hospital, Newcastle, NSW 2305, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Fietz","sequence":"additional","affiliation":[{"name":"National Referral Laboratory for Lysosomal, Peroxisomal and Related Genetic Disorders, SA Pathology at The Women's and Children's Hospital, North Adelaide, SA 5006, Australia"},{"name":"School of Molecular and Biomedical Science, University of Adelaide, Adelaide, SA 5005, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David R.","family":"Sullivan","sequence":"additional","affiliation":[{"name":"Department of Clinical Biochemistry, Royal Prince Alfred Hospital, Sydney, Camperdown, NSW 2050, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"98","reference":[{"issue":"8","key":"1","doi-asserted-by":"crossref","first-page":"403","DOI":"10.1093\/qjmed\/94.8.403","volume":"94","year":"2001","journal-title":"Monthly Journal of the Association of Physicians"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1046\/j.0022-3042.2002.00766.x"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M513198200"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M507528200"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1086\/346093"},{"issue":"2-3","key":"6","first-page":"7136","volume":"24","year":"2006","journal-title":"International Journal of Developmental Neuroscience"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M204639200"},{"issue":"8","key":"8","doi-asserted-by":"crossref","first-page":"772","DOI":"10.1007\/s00347-005-1239-x","volume":"102","year":"2005","journal-title":"Ophthalmologe"},{"issue":"9","key":"9","doi-asserted-by":"crossref","first-page":"559","DOI":"10.1177\/014107689108400919","volume":"84","year":"1991","journal-title":"Journal of the Royal Society of Medicine"},{"issue":"10","key":"10","doi-asserted-by":"crossref","first-page":"602","DOI":"10.1177\/014107688808101017","volume":"81","year":"1988","journal-title":"Journal of the Royal Society of Medicine"},{"issue":"3","key":"11","doi-asserted-by":"crossref","first-page":"171","DOI":"10.1177\/014107689308600319","volume":"86","year":"1993","journal-title":"Journal of the Royal Society of Medicine"}],"container-title":["Journal of Obesity"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jobe\/2011\/482021.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jobe\/2011\/482021.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jobe\/2011\/482021.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,6,3]],"date-time":"2023-06-03T03:23:56Z","timestamp":1685762636000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jobe\/2011\/482021\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":11,"alternative-id":["482021","482021"],"URL":"https:\/\/doi.org\/10.1155\/2011\/482021","relation":{},"ISSN":["2090-0708","2090-0716"],"issn-type":[{"value":"2090-0708","type":"print"},{"value":"2090-0716","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011]]}}}
