ObjectivesAlthough beriberi is considered a forgotten disease in the West, Kashmir has a rice-eating population that has beriberi in endemic proportions. Patients with a thiamine deficiency (TD) occasionally present with gastrointestinal (GI) symptoms, including nausea, recurrent vomiting, loss of appetite, and abdominal discomfort. Together these often respond to thiamine, which points to gastric beriberi.MethodsPatients with GI symptoms suggestive of TD were recruited from the Department of Medicine at the Government Medical College and its associated hospital, SMHS, in Srinagar, India. Patients were evaluated for serum thiamine levels, serum lactate, biochemical parameters, and transabdominal ultrasonography after ruling out the usual causes of acute abdominal pain and vomiting.ResultsA total of 27 patients were recruited with a mean age of 47.28 ± 20.84 y. The mean lactate of patients at the time of admission was 6.43 ± 5.22 mmol/L, and the mean lactate at the time of discharge was 1.23 ± 0.50 mmol/L. All patients had a history of consuming polished rice, washed two to three times before cooking, as the staple diet. The most common GI symptoms were recurrent vomiting, nausea, and loss of appetite. All of the patients responded to the thiamine treatment, and showed improvement in their GI symptoms and decreased serum lactate levels within 2 to 6 h of their hospital stay.ConclusionsGastric beriberi is a rare presentation of TD that can lead to severe GI symptoms and lactic acidosis. Given the rapid response to thiamine, it is the standard-of-care treatment in such cases. Thus, clinicians should suspect TD when patients present with either mild or moderate-to-severe GI symptoms and raised blood lactate.Copyright © 2022 Elsevier Inc. All rights reserved.
