There is an increased need for vitamin B1 (1\u20131.2\u2009mg daily) during pregnancy and lactation. Hyperemesis during pregnancy can cause severe polyneuropathy (Wernicke\u2019s encephalopathy) as a result of thiamine deficiency. Thiamine deficiency has also been associated with beriberi. A number of atypical cases with reversible right heart failure and severe pulmonary hypertension have also been reported in non-pregnant individuals, but have never been reported in pregnancy. Here we present five such cases of thiamine deficiency with neurological and cardio-pulmonary manifestations. <\/jats:p>","DOI":"10.1177\/1753495x20960906","type":"journal-article","created":{"date-parts":[[2020,10,14]],"date-time":"2020-10-14T06:22:03Z","timestamp":1602656523000},"page":"263-268","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["A case series of rare neurological and cardio-pulmonary manifestations of thiamine deficiency in pregnancy and lactation"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2357-2522","authenticated-orcid":false,"given":"Nivedita","family":"Hegde","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"AJ","family":"Ashwal","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shrayva","family":"Deekonda","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KK","family":"Suresh","sequence":"additional","affiliation":[{"name":"Department of Radiology, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,10,13]]},"reference":[{"key":"bibr1-1753495X20960906","first-page":"134","volume":"27","author":"Martin PR","year":"2003","journal-title":"Alcohol Res Health"},{"key":"bibr2-1753495X20960906","unstructured":"Martel JL, Franklin DS.
