Previous investigations on this regard were mainly conducted on chronic schizophrenia and lacked control for confounders. We aim to investigate the role of familial liability, childhood maltreatment and recent stress in determining cytokine abnormalities at the onset of psychosis.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291719001016_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>We recruited 114 first-episode psychosis (FEP) patients, 57 unaffected biological siblings of FEP patients, and 251 community-based controls. Plasma cytokines (IL-1<jats:italic>\u03b2<\/jats:italic>, IL-6, TNF-<jats:italic>\u03b1<\/jats:italic>, IFN-<jats:italic>\u03b3<\/jats:italic>, IL-4, IL-10 and TGF-<jats:italic>\u03b2<\/jats:italic>) were measured and differences across the groups analysed after adjusting for potential confounders.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291719001016_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>FEP had a higher pro- and anti-inflammatory cytokine profile (IL-1<jats:italic>\u03b2<\/jats:italic>, IL-6, TNF-<jats:italic>\u03b1<\/jats:italic>, IL-10 and TGF-<jats:italic>\u03b2<\/jats:italic>), which was not observed in unaffected siblings. Siblings presented decreased IL-1<jats:italic>\u03b2<\/jats:italic> when compared with patients and controls. Childhood maltreatment was associated with higher levels of TGF-<jats:italic>\u03b2<\/jats:italic> in both patients and siblings when compared with controls. Physical childhood abuse was associated with increased levels of TGF-<jats:italic>\u03b2<\/jats:italic> in FEP patients but with decreased levels in controls. Other childhood maltreatment subtypes or recent stressors did not affect cytokine levels in any of the groups.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291719001016_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>Normal or reduced cytokines in siblings represent possibly a protective factor and suggest that the identified inflammatory profile in FEP can be a real pathophysiological component of psychosis. Experience of childhood maltreatment may contribute as long-term immune priming for the TGF-<jats:italic>\u03b2<\/jats:italic> pathway, and increased levels of this cytokine in both patients and siblings exposed to childhood maltreatment point to a possible biological candidate of familial risk for psychosis.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0033291719001016","type":"journal-article","created":{"date-parts":[[2019,5,8]],"date-time":"2019-05-08T08:08:05Z","timestamp":1557302885000},"page":"1139-1147","source":"Crossref","is-referenced-by-count":53,"title":["Cytokine profile in first-episode psychosis, unaffected siblings and community-based controls: the effects of familial liability and childhood maltreatment"],"prefix":"10.1017","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9202-3987","authenticated-orcid":false,"given":"Fabiana","family":"Corsi-Zuelli","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Camila Marcelino","family":"Loureiro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosana","family":"Shuhama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helene Aparecida","family":"Fachim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo Rossi","family":"Menezes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo","family":"Louzada-Junior","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeria","family":"Mondelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina Marta","family":"Del-Ben","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2019,5,8]]},"reference":[{"key":"S0033291719001016_ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbi.2017.06.005"},{"key":"S0033291719001016_ref36","doi-asserted-by":"publisher","DOI":"10.1097\/PSY.0000000000000049"},{"key":"S0033291719001016_ref30","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpsychires.2007.04.002"},{"key":"S0033291719001016_ref35","doi-asserted-by":"crossref","first-page":"421","DOI":"10.1038\/nature13595","article-title":"Biological insights from 108 schizophrenia-associated genetic loci","volume":"511","author":"Ripke","year":"2014","journal-title":"Nature"},{"key":"S0033291719001016_ref39","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.0789-10.2010"},{"key":"S0033291719001016_ref8","doi-asserted-by":"publisher","DOI":"10.1017\/S003329170002105X"},{"key":"S0033291719001016_ref27","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2018.06.037"},{"key":"S0033291719001016_ref11","doi-asserted-by":"publisher","DOI":"10.1111\/acps.12217"},{"key":"S0033291719001016_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.psyneuen.2018.05.021"},{"key":"S0033291719001016_ref10","doi-asserted-by":"publisher","DOI":"10.1084\/jem.20030152"},{"key":"S0033291719001016_ref17","doi-asserted-by":"publisher","DOI":"10.1017\/S1461145710001653"},{"key":"S0033291719001016_ref37","doi-asserted-by":"publisher","DOI":"10.1038\/tp.2017.47"},{"key":"S0033291719001016_ref29","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbi.2016.09.008"},{"key":"S0033291719001016_ref33","article-title":"A meta-analysis of immune parameters, variability, and assessment of modal distribution in psychosis and test of the immune subgroup hypothesis","author":"Pillinger","year":"2018","journal-title":"Schizophrenia Bulletin"},{"key":"S0033291719001016_ref38","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2005.04.018"},{"key":"S0033291719001016_ref13","doi-asserted-by":"publisher","DOI":"10.1590\/S1516-44462001000300008"},{"key":"S0033291719001016_ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbi.2012.06.010"},{"key":"S0033291719001016_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/S0145-2134(02)00541-0"},{"key":"S0033291719001016_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2010.07.001"},{"key":"S0033291719001016_ref42","doi-asserted-by":"publisher","DOI":"10.1590\/1413-81232015203.15242014"},{"key":"S0033291719001016_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.schres.2013.03.027"},{"key":"S0033291719001016_ref28","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291716003263"},{"key":"S0033291719001016_ref25","doi-asserted-by":"publisher","DOI":"10.1001\/jamapsychiatry.2014.1332"},{"key":"S0033291719001016_ref18","unstructured":"First, MB , Spitzer, RL , Gibbon, M and Williams, JBW (1997) Structured clinical interview for DSM-IV axis I disorders SCID-I: clinician version, administration booklet.
