In case of failure of one procedure, the best sequential choice was a polymerase chain reaction analysis after a negative histology. Of the five strategies tested for cases with predominant focal neurological involvement, the stereotaxis cerebral biopsy evidenced the highest expected value. However, using quality\u2010adjusted life\u2010years considering the morbidity of methods, intestinal biopsy for PCR determination was the best choice.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In patients with Whipple's disease having predominant digestive involvement, intestinal biopsies for histology should be indicated first and, if negative, a bacterial polymerase chain reaction determination should be the next option. Although the molecular polymerase chain reaction assessment of cerebral biopsies has the highest diagnostic yield in neurological Whipple's disease, its associated morbidity means that analyses of intestinal samples are more appropriate.<\/jats:p><\/jats:sec>","DOI":"10.1111\/j.1365-2036.2006.02822.x","type":"journal-article","created":{"date-parts":[[2006,2,27]],"date-time":"2006-02-27T17:05:56Z","timestamp":1141059956000},"page":"833-840","source":"Crossref","is-referenced-by-count":10,"title":["Decision analysis: an aid to the diagnosis of Whipple's disease"],"prefix":"10.1111","volume":"23","author":[{"given":"M.","family":"OLMOS","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"SMECUOL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"MAURI\u00d1O","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
