The aim of this study was to assess whether circulating SIRT1 varies consistently with leptin, ghrelin, body mass index (BMI), and IgG reactive to hypothalamic antigens in anorexia nervosa (AN). Fifty-four subjects were evaluated: 32 with AN and 22 normal-weight control subjects. Serum levels of SIRT1, leptin, ghrelin, and IgG reactive to hypothalamic antigens were evaluated by ELISA. Results showed that serum SIRT1 is increased in patients with AN, and the amount is decreased in relation to the duration of the illness. SIRT1 concentration approaches the values obtained for the control group, although the difference is still statistically significant. A negative correlation between serum SIRT1 values and leptin or BMI values has been found. On the contrary, a positive correlation between SIRT1 and ghrelin or IgG specific for hypothalamic antigens is reported. These findings suggest that a peripheral evaluation of SIRT1 could be a possible clinical\/biochemical parameter related to AN. In addition, we can assume that SIRT1 is related to autoantibody production and may correlate with the intensity\/severity of AN. Thus, reducing the production of autoantibodies specific for hypothalamic cells could be a sign of improvement of the clinical condition.<\/jats:p>","DOI":"10.3390\/jpm13060928","type":"journal-article","created":{"date-parts":[[2023,5,31]],"date-time":"2023-05-31T03:59:35Z","timestamp":1685505575000},"page":"928","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Association between Blood SIRT1 and Ghrelin, Leptin, and Antibody Anti-Hypothalamus: A Comparison in Normal Weight and Anorexia Nervosa"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3439-340X","authenticated-orcid":false,"given":"Andrea","family":"Amerio","sequence":"first","affiliation":[{"name":"Department of Neuroscience, Rehabilitation, Ophthalmology, Genetics, Maternal and Child Health (DiNOGMI), Section of Psychiatry, University of Genoa, 16132 Genoa, Italy"},{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Escelsior","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Rehabilitation, Ophthalmology, Genetics, Maternal and Child Health (DiNOGMI), Section of Psychiatry, University of Genoa, 16132 Genoa, Italy"},{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleonora","family":"Martino","sequence":"additional","affiliation":[{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"},{"name":"Dietetics and Clinical Nutrition Unit, Genoa University, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonella","family":"Strangio","sequence":"additional","affiliation":[{"name":"Department of Experimental Medicine (DiMeS), Section of Human Anatomy, University of Genoa, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2003-2101","authenticated-orcid":false,"given":"Andrea","family":"Aguglia","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Rehabilitation, Ophthalmology, Genetics, Maternal and Child Health (DiNOGMI), Section of Psychiatry, University of Genoa, 16132 Genoa, Italy"},{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo","family":"Marcatili","sequence":"additional","affiliation":[{"name":"Department of Mental Health, Fondazione IRCCS San Gerardo dei Tintori, 20900 Monza, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benedetta","family":"Conio","sequence":"additional","affiliation":[{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4194-1547","authenticated-orcid":false,"given":"Samir Giuseppe","family":"Sukkar","sequence":"additional","affiliation":[{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"},{"name":"Dietetics and Clinical Nutrition Unit, Genoa University, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniele","family":"Saverino","sequence":"additional","affiliation":[{"name":"IRCCS Ospedale Policlinico San Martino, 16132 Genoa, Italy"},{"name":"Department of Experimental Medicine (DiMeS), Section of Human Anatomy, University of Genoa, 16132 Genoa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2013).
