PATINO, John A.  and  OLIVERA, Mario J.. Gastro-allergic anisakiasis: The first case reported in Colombia and a literature review. Biomédica [online]. 2019, vol.39, n.2, pp.241-246. ISSN 0120-4157.  https://doi.org/10.7705/biomedica.v39i2.3936.

Anisakiasis is a zoonotic parasitic disease caused by consumption of raw or undercooked fish or seafood infected with nematodes of the Anisakis, Pseudoterranova or Contracaecum genera.

Here, we describe the first case of anisakiasis in Colombia and summarize the available literature. A 52-year-old female with a history of abrupt-onset sharp epigastric pain, nausea, vomit, diarrhea, and urticaria following fish consumption consulted the health service.

The physical examination revealed moderate tenderness of the epigastric region; the laboratory evaluation showed leukocytosis and a simple X-ray and ECG showed no abnormalities. The diagnosis was made by endoscopic examination, which revealed a thickened gastric wall and a moving larval worm. An Anisakis larva was found and extracted endoscopically, which relieved the pain of the patient.

Clinically, anisakiasis may present as a gastric, intestinal, extragastrointestinal or allergic disease. Diagnosis and treatment of anisakiasis are made by a dietary history, direct visualization and endoscopic extraction of possible larvae, which is the only effective therapy.

Keywords : Anisakis; nematoda; foodborne diseases; hypersensitivity; gastrointestinal diseases; Colombia.
