Résumé
Resumen La anisakiasis es una enfermedad parasitaria zoonótica causada por el consumo de pescados o mariscos crudos o poco cocidos infectados con nematodos de los géneros Anisakis, Pseudoterranova y Contracaecum. Se describe el primer caso de anisakiasis en Colombia y se resume la literatura médica disponible. Una mujer de 52 años de edad consultó por dolor epigástrico agudo de inicio abrupto, náuseas, vómitos, diarrea y urticaria después de consumir pescado. El examen físico reveló sensibilidad moderada en el epigastrio. El examen de laboratorio evidenció leucocitosis, en tanto que la radiografía simple y el electrocardiograma no reflejaron ninguna anormalidad. El diagnóstico se hizo mediante una endoscopia de vías digestivas altas, la cual reveló engrosamiento de la pared gástrica y un parásito en movimiento. Se encontró una larva de Anisakis y se la extrajo por endoscopia, lo que alivió el dolor de la paciente. Clínicamente, la anisakiasis puede presentarse como una enfermedad gástrica, intestinal, en otros sistemas o alérgica. El diagnóstico se hace con base en la elaboración del historial alimentario del paciente y la visualización directa de las larvas; el único tratamiento efectivo consiste en su extracción endoscópica.
Abstract 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.

Several reports on taeniasis and cysticercosis in Vietnam show that they are distributed in over 50 of 63 provinces. In some endemic areas, the prevalence of taeniasis was 0.2-12.0% and that of cysticercosis was 1.0-7.2%. The major symptoms of taeniasis included fidgeted anus, proglottids moving out of the anus, and proglottids in the feces. Clinical manifestations of cysticercosis in humans included subcutaneous nodules, epileptic seizures, severe headach, impaired vision, and memory loss. The species identification of Taenia in Vietnam included Taenia asiatica, Taenia saginata, and Taenia solium based on combined morphology and molecular methods. Only T. solium caused cysticercosis in humans. Praziquantel was chosen for treatment of taeniasis and albendazole for treatment of cysticercosis. The infection rate of cysticercus cellulosae in pigs was 0.04% at Hanoi slaughterhouses, 0.03-0.31% at provincial slaughterhouses in the north, and 0.9% in provincial slaughterhouses in the southern region of Vietnam. The infection rate of cysticercus bovis in cattle was 0.03-2.17% at Hanoi slaughterhouses. Risk factors investigated with regard to transmission of Taenia suggested that consumption of raw meat (eating raw meat 4.5-74.3%), inadequate or absent meat inspection and control, poor sanitation in some endemic areas, and use of untreated human waste as a fertilizer for crops may play important roles in Vietnam, although this remains to be validated.
