Two hundred and twenty stool samples from patients with a variety of HIV related conditions were analysed for faecal alpha 1 antitrypsin. Patients with intestinal Kaposi's sarcoma had a significantly raised faecal alpha 1 antitrypsin value and hypoalbuminaemia. A faecal alpha 1 antitrypsin value of greater than 0.3 mg\/g wet stool has a sensitivity of 94% and a specificity of 76% for the diagnosis of intestinal Kaposi's sarcoma in HIV positive individuals. Patients with cytomegalovirus and bacterial enteritis had raised faecal alpha 1 antitrypsin values but levels were normal for all other intestinal pathologies compared with pathogen negative stool. The combination of faecal alpha 1 antitrypsin concentration greater than 0.2 mg\/g, a negative stool culture for enteric bacteria, and the absence of palatal Kaposi's sarcoma has a sensitivity of 55% and specificity of 88% for the diagnosis of enteric cytomegalovirus infection.<\/jats:p>","DOI":"10.1136\/gut.38.2.206","type":"journal-article","created":{"date-parts":[[2007,9,18]],"date-time":"2007-09-18T17:41:31Z","timestamp":1190137291000},"page":"206-210","source":"Crossref","is-referenced-by-count":8,"title":["Faecal alpha 1 antitrypsin as a marker of gastrointestinal disease in HIV antibody positive individuals."],"prefix":"10.1136","volume":"38","author":[{"given":"D","family":"Sharpstone","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Rowbottom","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Nelson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Gazzard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1996,2,1]]},"reference":[{"key":"ref_1","first-page":"288","article-title":"Nutritional status, gastrointestinal dysfunction, and survival in patients with AIDS","volume":"84","author":"Chlebowski, R.T.; Grosvenor, M.B.; Bernhard, N.H.; Morales, L.S.; Bulcavage, L.M.","year":"1989","unstructured":"Chlebowski RT, Grosvenor MB, Bernhard NH, Morales LS, Bulcavage LM.
