Shoshin beriberi is a fulminant form of wet beriberi, but there are no large-scale studies detailing the clinical features of this disease. We investigated the clinical features and outcomes of Shoshin beriberi using data from a nationwide database in Japan.

Using the Diagnosis Procedure Combination database, we identified patients with Shoshin beriberi between July 2010 and March 2021. We retrospectively investigated the characteristics, comorbidities, treatment, and in-hospital mortality of patients with Shoshin beriberi. The chi-square test or Fisher's exact test was used for categorical variables, and the Mann-Whitney U-test was used for continuous variables.

We identified 62 patients with Shoshin beriberi. The median (interquartile range) age was 63 (48-69) years. Furthermore, 54 patients were male (87%). The most common comorbidity was alcohol-related disorder (34%). The median (interquartile range) length of hospital and intensive care unit stays were 17 (range, 10-35) and 5 (range, 1-9) days, respectively. The proportion of patients who received venoarterial extracorporeal membrane oxygenation, intra-aortic balloon pump, continuous renal replacement therapy, and mechanical ventilation was 11, 5, 29, and 63%, respectively. Among the patients with Shoshin beriberi, 53% received 2 or more catecholamines or inotropes. The in-hospital mortality was 23%. Impaired consciousness at admission was significantly related to in-hospital death (P < 0.001).

The present study is the first and largest to describe the clinical features of patients with Shoshin beriberi using a nationwide database. Impaired consciousness at admission was significantly associated with in-hospital death.
