Rev Esp Enferm Dig. 2024 Oct;116(10):564-565. doi: 10.17235/reed.2024.10621/2024.

Abstract

We present 4 clinical cases of intestinal spirochetosis. The first one presents with chronic diarrhea, and spirochetes are detected in random biopsies. The second is homosexual, HIV+, presents rectal bleeding, colonoscopy shows a straight ulcer and spirochete biopsies show negative treponema PCR. The third was also homosexual, HIV+, asymptomatic, with a chance finding of spirochetosis. The last case is also a chance histological diagnosis in a patient with inactive ulcerative colitis without lesions. Intestinal spirochetosis appears to be transmitted sexually and by consumption of contaminated water. The majority are asymptomatic cases but could cause lesions including ulcerations and symptoms. Treatment is only recommended in symptomatic or immunosuppressed patients. It must be distinguished from lesions caused by Treponema pallidum.
