While higher levels of cortisol and MN were found only in a selected subgroup of highly compromised subjects (p &lt; 0.001 and p &lt; 0.005, respectively), \u03b2-endorphin increased significantly under conditions of moderate or severe intrauterine sufferance (p &lt; 0.001 in both cases). Due to higher levels of the opioid even during the initial stage of fetal discomfort we evaluated its characteristics as a possible clinical marker. Specificity was 88.5%, whereas the sensitivity of 65.6% in the moderately compromised subgroup increased to 88.9% in severely suffering fetuses. Although more accurate and mainly real-time information on the fetal health status is obtained by means of biophysical methods, the determination of amniotic fluid \u03b2-endorphin might be of clinical usefulness in prenatal diagnosis.<\/jats:p>","DOI":"10.1159\/000263952","type":"journal-article","created":{"date-parts":[[2009,11,27]],"date-time":"2009-11-27T20:36:55Z","timestamp":1259354215000},"page":"300-305","source":"Crossref","is-referenced-by-count":6,"title":["Stress Mediators in the Amniotic Compartment in Relation to the Degree of Fetal Distress"],"prefix":"10.1159","author":[{"given":"Alessandro","family":"Mauri","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annibale","family":"Volpe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,11,26]]},"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000263952","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T12:53:05Z","timestamp":1777553585000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000263952"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,11,26]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000263952","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,11,26]]}}}
