A Case of Intestinal Spirochete Infection Treated with Daikenchuto Extract

Abstract

Intestinal spirochetosis is a rare gastrointestinal infection caused by Brachyspira. Clinical manifestations vary, ranging from asymptomatic infection to gastrointestinal bleeding, diarrhea, or abdominal pain. Antimicrobial medications such as metronidazole are routinely given, but their clinical efficacy has not determined with any precision. We report a case of intestinal spirochetosis treated with daikenchuto extract with literature reviews. Treatment of intestinal spirochetosis can be difficult, and use of daikenchuto extract may be an option especially for patients with symptoms such as chronic diarrhea, abdominal distention, or change in flatus.
