Background
Microbiology
- Gastrointestinal flagellated protozoan parasite
Life Cycle
- Unclear, but may inoculate humans via pinworm eggs
Clinical Manifestations
- There exists some debate about its pathogenicity
- Many cases are asymptomatic and incidental on stool ova & parasite
- Attributable symptoms, when present, vague abdominal pain, bloating, diarrhea, fatigue, weight loss and anorexia
Management
- Look for coinfection with Enterobius vermicularis
- If symptomatic, treat with:
- Iodoquinol 650 mg orally three times daily for 20 days
- Paromomycin 25–35 mg per kg per day orally, in three divided doses, for 7 days
- Metronidazole 500–750 mg orally three times daily for 10 days, though this may be associated with a higher rate of recurrence
