Taeniasis: A possible cause of ileal bleeding

Area of Science:

• Medical parasitology
• Gastroenterology

Background:

• Taenia spp. (tapeworms) are cestodes with humans as definitive hosts.
• Human taeniasis, typically asymptomatic, results from ingesting undercooked meat with tapeworm larvae.
• Standard therapies include anthelmintics like albendazole, niclosamide, and praziquantel.

Observation:

• A case of acute ileal bleeding was observed in an Italian man.
• The patient presented with Taenia spp. infestation resistant to albendazole.
• The patient also had Helicobacter pylori-associated duodenal ulcers.

Findings:

• This case suggests a potential link between Taenia spp. infestation and gastrointestinal hemorrhage.
• Ileal bleeding is not a commonly recognized complication of taeniasis.
• The resistance to albendazole indicates a need for alternative treatment strategies.

Implications:

• This case expands the understanding of Taenia spp. complications, including potential gastrointestinal bleeding.
• It underscores the importance of considering parasitic infections in unexplained gastrointestinal bleeding.
• Further research is needed to explore the pathophysiology and management of severe taeniasis.
