Through modulation of the intestinal microbiota, probiotic supplements may moderate the effects of sleep disruption on the immune system. The aim of this study was to examine 14 days of daily probiotic supplementation on the acute response of acute phase proteins and immune markers to sleep disruption associated with night shift work (Australia and New Zealand Clinical Trials Registry: 12617001552370).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Individuals (mean age 41 \u00b1 11 yrs; 74% female) performing routine night shift were randomly assigned to a probiotic group (1 \u00d7 10<jats:sup>10<\/jats:sup> colony forming units (CFU) <jats:italic>Lactobacillus acidophilus<\/jats:italic> DDS-1 or 1 \u00d7 10<jats:sup>10<\/jats:sup> CFU <jats:italic>Bifidobacterium animalis<\/jats:italic> subsp. <jats:italic>lactis<\/jats:italic> UABla-12) or placebo (n= 29 per group). Participants undertook a 14-day supplementation period that coincided with a period of no night shifts followed by two consecutive night shifts. Blood samples were collected prior to the start of supplementation (V1), prior to commencing the first night shift (V2), after the first night shift (V3) and after the second night shift (V4). Serum was assessed for markers of stress (cortisol), acute phase response (C reactive protein (CRP), erythrocyte sedimentation rate, pentraxin), adhesion markers (serum E-selectin, mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1), and serum cytokines (interleukin (IL)-1ra, IL-1\u03b2, IL-6, tumor necrosis factor (TNF)-\u03b1, IL-10). Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) and a Fitbit activity tracker.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The groups were well balanced on key markers and the probiotic strains were well tolerated. The 14-day supplementation period that coincided with typical night-day sleep-wake cycles leading up to night shift (V1 to V2) was associated with significant changes in the placebo group in the concentration of serum cortisol (p = 0.01), pentraxin (p = 0.001), MAdCAM-1 (p = 0.001), and IL-1ra (p=0.03). In contrast, probiotic supplementation moderated changes in these serum markers from V1 to V2. No significant interaction effects (time by group) were observed for the serum markers prior to and after night shift work following probiotic supplementation due to the substantial changes in the serum markers that occurred during the normal sleep period from V1 to V2.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Probiotics may moderate the effects of anticipatory stress on the immune system in the lead up to night shift.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fimmu.2020.599547","type":"journal-article","created":{"date-parts":[[2021,1,28]],"date-time":"2021-01-28T17:38:06Z","timestamp":1611855486000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":27,"title":["Probiotics, Anticipation Stress, and the Acute Immune Response to Night Shift"],"prefix":"10.3389","volume":"11","author":[{"given":"Nicholas P.","family":"West","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lily","family":"Hughes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Ramsey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher J.","family":"Martoni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory J.","family":"Leyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allan W.","family":"Cripps","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amanda J.","family":"Cox","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,1,28]]},"reference":[{"key":"B1","doi-asserted-by":"crossref","DOI":"10.1213\/ANE.0000000000002698","article-title":"The Night Shift Nightmare","volume-title":"Anesth Analg","author":"Kiley","year":"2018"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2019.06.015","article-title":"A societal sleep prescription","volume":"103","author":"Walker","year":"2019","journal-title":"Neuron"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.00010.2018","article-title":"The sleep-immune crosstalk in health and disease","volume":"99","author":"Besedovsky","year":"2019","journal-title":"Physiol Rev"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbi.2007.04.003","article-title":"KP.
