Abstract

Thiamine (vitamin B1) is a sulfur-containing, water-soluble vitamin that plays an essential role in energy metabolism and the tricarboxylic acid cycle. There is an increased need for vitamin B1 (1–1.2 mg daily) during pregnancy and lactation. Hyperemesis during pregnancy can cause severe polyneuropathy (Wernicke’s 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.
