Gnatostomiasis cutánea, primer caso confirmado en Colombia

Abstract

: estudio patológico e identificación del espécimen Leonardo F. Jurado: contribución en la identificación del parasito, revisión de la historia clínica y de la literatura científica pertinente Todos los autores participaron en la escritura del manuscrito. La gnatostomiasis es una zoonosis parasitaria causada por algunas especies del género de helmintos Gnathostoma. La presentación clínica es muy variada y su diagnóstico constituye un desafío; es endémica en países tropicales y subtropicales, y la transmisión se asocia con el consumo de carne de animales acuáticos, cruda o mal cocida. En las últimas décadas, el creciente turismo internacional y el consumo de alimentos exóticos, han provocado un notable aumento de casos de la enfermedad. En nuestro país no se ha reportado ningún caso confirmado de gnatostomiasis. Se presenta el caso de un hombre colombiano de 63 años de edad, viajero frecuente al exterior, que consultó por presentar síntomas gastrointestinales. Durante la hospitalización desarrolló una lesión cutánea en el flanco abdominal derecho, de la cual se extrajo una larva cuya descripción morfológica permitió clasificarla como Gnathostoma spinigerum. Se trata de la primera confirmación de un caso importado de gnatostomiasis en Colombia. En este artículo se discuten las generalidades, la etiología, la patogenia y el tratamiento de la enfermedad, con especial énfasis en las características particulares de este paciente. Gnatostomiasis cutánea, primer caso confirmado en ColombiaPalabras clave: gnatostomiasis/diagnóstico, Gnathostoma, Larva migrans, parasitosis intestinales, zoonosis, Colombia. doi: http://dx.doi.org/10.7705/biomedica.v35i4.2547 Cutaneous gnathostomiasis, first confirmed case in ColombiaGnathostomiasis is a parasitic zoonosis caused by some species of helminthes belonging to the genus Gnathostoma. It has a wide clinical presentation and its diagnosis is a challenge. Tropical and subtropical countries are endemic, and its transmission is associated with eating raw or undercooked meat from fresh water animals. Increasing global tourism and consuming exotic foods have produced a noticeable rise in cases of the disease in the last decades. However, in our country, there has not been any confirmed case of gnathostomiasis previously reported. We present the case of a 63-year-old Colombian man with an international travel history, who presented with gastrointestinal symptoms. During the hospital stay, he developed a cutaneous lesion on the upper right abdominal quadrant, where later, a larva was found. A morphological study allowed us to identify it as Gnathostoma spinigerum. As such, this is the first report of an imported case of gnathostomiasis confirmed in Colombia. This article describes the principles, etiology, pathogenic cycle and treatment of this disease with special considerations to our patient's particular features.

Case Report: Ocular Gnathostomiasis in Venezuela Most Likely Acquired in Texas

“…1,2 In addition, few sporadic indigenous gnathostomiasis cases have been reported from several South American countries 16 such as Brazil, 4,5 Peru, 6 Argentina, 17 and Colombia. 18 Nevertheless, not much attention has been paid for gnathostomiasis in Venezuela, until recent report of an indigenous case of cutaneous gnathostomiasis in a 25-year-old man who went to Apure State for game fishing and consumed a raw freshwater fish. 19 Similar to the present case, the first gnathostomiasis case in Colombia 18 was a 63-year-old male international traveler with a recent history of travel to the United States.…”

Game fishing, especially in angling spots in United States, seems to be an important risk factor for gnathostomiasis.…”

Abdominal angiostrongyliasis, report of two cases and analysis of published reports from Colombia

“…Third, underdiagnosis makes it difficult to establish a real incidence. It is important to take into account that due to social and cultural changes during the last decades such as the increase in international tourism and migration trends 33 , the epidemiological pattern of this disease has changed. For this reason, cases may appear outside of its originally endemic area.…”

Gnathostomiasis: an emerging infectious disease relevant to all dermatologists

“…Imported and autochthonous cases have been recently reported in Brazil 7 , 15 , Colombia, 16 and Korea. 17 In the specific case of Brazil, one patient developed gnathostomiasis after traveling to Peru, while the patient reported by Vargas was infected after consuming local raw peacock bass ( Cichla spp ) during a fishing trip to the state of Tocantins.…”
