Thiamin is closely involved in carbohydrate metabolism, and in thiamin\u2010deficient states, increased lactic acid levels can be found, exacerbated by critical illness. This integrative literature review focused on the relationship between supplemental thiamin, lactate clearance, and impact on mortality in sepsis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A search in PubMed, Embase, and CINAHL was conducted for literature published between January 2016 and January 2021. We included observational studies and clinical trials with \u226510 participants. We excluded studies involving pediatric (&lt;18 years old) populations, animal studies, case studies, dropout rate of &gt;20%, nonhospitalized patients, or patients receiving comfort measures only.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 48 full\u2010text articles were assessed for eligibility, with 15 evaluated for this integrative review. Included were five retrospective, two prospective observational, and eight randomized controlled trials. In almost all retrospective studies, thiamin administration was associated with decreased mortality, and in observational studies, with decreased lactate and improved clinical outcomes. In clinical trials, thiamin with or without vitamin C\/hydrocortisone did not impact clinical outcomes or mortality. However, four trials testing intravenous thiamin 200\u2013500\u2009mg two to three times daily for up to 3 days reported improved lactate clearance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Thiamin supplementation may improve lactate clearance when administered in the first 24\u2009h. Those deficient in thiamin may benefit more from supplementation. The combination of thiamin, vitamin C, and\/or hydrocortisone may not be advantageous. Lactate reduction in response to thiamin needs further rigorous research.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ncp.10930","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T06:28:57Z","timestamp":1673504937000},"page":"580-601","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Impact of supplemental thiamin on lactate levels in adults with septic shock"],"prefix":"10.1002","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9802-6839","authenticated-orcid":false,"given":"Paul A.","family":"Blakeslee","sequence":"first","affiliation":[{"name":"Clinical Nutrition Program Maine Medical Center  Portland Maine USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristiina","family":"Hyrk\u00e4s","sequence":"additional","affiliation":[{"name":"Center for Nursing Research and Quality Outcomes Maine Medical Center  Portland Maine USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0000000000003342"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2016.0287"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/SHK.0000000000000958"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/nchembio.2172"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/2608318"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-018-5213-x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCE.0000000000000087"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/SHK.0000000000000861"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/1178633719862776"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0000000000000742"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrc.2016.09.023"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000018894"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2016.04.32"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1515\/jbcpp-2018-0075"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/MCO.0b013e32834b8911"},{"key":"e_1_2_8_17_1","volume-title":"Evidence Analysis Manual: Steps in the Academy Evidence Analysis Process","author":"Research, International and Strategic Business Development Team, Academy of Nutrition and Dietetics","year":"2016"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0000000000001572"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12871-020-01195-4"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0000000000003311"},{"key":"e_1_2_8_21_1","article-title":"The effect of thiamine administration on interleukin\u20106 (Il\u20106) enzyem, lactate and sequential organ failure assessment (SOFA) score in patients with sepsis","volume":"9","author":"Nasution AH","year":"2020","journal-title":"J Drug Alcohol Res"},{"issue":"6","key":"e_1_2_8_22_1","first-page":"288","article-title":"Intravenous thiamine as an adjuvant therapy for hyperlactatemia in septic shock patients","volume":"22","author":"Harun NF","year":"2019","journal-title":"Crit Care Shock"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrc.2017.08.022"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0000000000002613"},{"issue":"6","key":"e_1_2_8_25_1","article-title":"Effect of intravenous vitamin C, thiamine, and hydrocortisone (the metabolic resuscitation protocol) on early weaning from vasopressors in patients with septic shock.
