This condition is associated with a pro-inflammatory state; however, the role of immunity in symptom severity remains unclear. Total cholesterol, white blood cells, neutrophils, lymphocytes, platelets, iron, folate, vitamin D and B12 were dosed in 84 female AN outpatients. Mildly severe (Body Mass Index\u2014BMI \u2265 17) versus severe (BMI &lt; 17) patients were compared using one-way ANOVAs or \u03c72 tests. A binary logistic regression model was run to investigate the potential association between demographic\/clinical variables or biochemical markers and the severity of AN. Patients with severe anorexia (compared to mild forms) were older (F = 5.33; p = 0.02), engaged in more frequent substance misuse (\u03c72 = 3.75; OR = 3.86; p = 0.05) and had a lower NLR (F = 4.12; p = 0.05). Only a lower NLR was predictive of severe manifestations of AN (OR = 0.007; p = 0.031). Overall, our study suggests that immune alterations may be predictive of AN severity. In more severe forms of AN, the response of the adaptive immunity is preserved, while the activation of the innate immunity may be reduced. Further studies with larger samples and a wider panel of biochemical markers are needed to confirm the present results.<\/jats:p>","DOI":"10.3390\/nu15051133","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T01:37:52Z","timestamp":1677202672000},"page":"1133","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Clinical and Peripheral Biomarkers in Female Patients Affected by Anorexia: Does the Neutrophil\/Lymphocyte Ratio (NLR) Affect Severity?"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8493-0779","authenticated-orcid":false,"given":"Alice","family":"Caldiroli","sequence":"first","affiliation":[{"name":"Department of Mental Health and Addiction, Fondazione IRCCS San Gerardo dei Tintori, Via G.B.
