An increased plasma clozapine level above the therapeutic window may be associated with serious adverse events including paralytic ileus. Clozapine toxicity may occur in association with infection or after drug overdose. In a medical emergency situation, differentiating between a toxic clozapine ingestion and an infection-induced toxicity might be hindered by associated CNS changes and by the clozapine modulation of the inflammatory process. This may delay prompt initiation of a tailored treatment strategy. Here, we report a case of paralytic ileus developed within the context of clozapine toxicity. Although the underlying cause of toxicity was not clinically obvious, giving antimicrobial therapy resulted in an improvement in the patient\u2019s clinical condition. This report indicates the value of serum levels of C-reactive protein and desmethylclozapine, major metabolite of clozapine, in the treatment of aetiologically unclear clozapine toxicity.<\/jats:p>","DOI":"10.1155\/2012\/592784","type":"journal-article","created":{"date-parts":[[2012,8,15]],"date-time":"2012-08-15T17:00:08Z","timestamp":1345050008000},"page":"1-4","source":"Crossref","is-referenced-by-count":5,"title":["The Value of Desmethylclozapine and Serum CRP in Clozapine Toxicity: A Case Report"],"prefix":"10.1155","volume":"2012","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0340-4644","authenticated-orcid":true,"given":"Khalid","family":"Abou Farha","sequence":"first","affiliation":[{"name":"QPS Netherlands B.V. 9713 GZ Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andre","family":"van Vliet","sequence":"additional","affiliation":[{"name":"PRA International, 9471 GP Zuidlaren, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henderikus","family":"Knegtering","sequence":"additional","affiliation":[{"name":"Lentis Mental Health Organisation, 9725 AG Groningen, The Netherlands"},{"name":"Rob Giel Onderzoekscentrum, Department of Psychiatry, University Medical Centre Groningen, University of Groningen, 9700 RB Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Bruggeman","sequence":"additional","affiliation":[{"name":"Rob Giel Onderzoekscentrum, Department of Psychiatry, University Medical Centre Groningen, University of Groningen, 9700 RB Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"4","key":"1","volume":"13","year":"2005","journal-title":"Graylands Hospital Drug Bulletin"},{"issue":"1","key":"2","volume":"21","year":"2007","journal-title":"Jefferson Journal of Psychiatry"},{"issue":"3","key":"3","doi-asserted-by":"crossref","first-page":"159","DOI":"10.3371\/CSRP.5.3.7","volume":"5","year":"2011","journal-title":"Clinical Schizophrenia & Related Psychoses"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2180-11-112"},{"issue":"3","key":"6","first-page":"1375","volume":"283","year":"1997","journal-title":"Journal of Pharmacology and Experimental Therapeutics"},{"issue":"3","key":"7","first-page":"27","volume":"13","year":"2006","journal-title":"Primary Psychiatry"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s00213-004-1850-6"},{"issue":"15","key":"9","doi-asserted-by":"crossref","first-page":"6385","DOI":"10.1523\/JNEUROSCI.23-15-06385.2003","volume":"23","year":"2003","journal-title":"Journal of Neuroscience"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2003.048041"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1055\/s-2003-39980"},{"issue":"12","key":"12","first-page":"1379","volume":"25","year":"1997","journal-title":"Drug Metabolism and Disposition"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-977X(98)00036-4"},{"issue":"4","key":"15","doi-asserted-by":"crossref","first-page":"702","DOI":"10.1086\/514958","volume":"27","year":"1998","journal-title":"Clinical Infectious Diseases"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1097\/jcp.0b013e31815a257f"},{"key":"18","doi-asserted-by":"crossref","first-page":"660","DOI":"10.1007\/s11626-996-0017-7","volume":"34","year":"1998","journal-title":"In Vitro Cellular & Developmental Biology"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1038\/ncpgasthep0167"}],"container-title":["Case Reports in Psychiatry"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crips\/2012\/592784.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crips\/2012\/592784.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crips\/2012\/592784.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,7,2]],"date-time":"2019-07-02T18:05:41Z","timestamp":1562090741000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crips\/2012\/592784\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":16,"alternative-id":["592784","592784"],"URL":"https:\/\/doi.org\/10.1155\/2012\/592784","relation":{},"ISSN":["2090-682X","2090-6838"],"issn-type":[{"value":"2090-682X","type":"print"},{"value":"2090-6838","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
