“…Popularmente conhecido como verme gigante do rim, Dioctophyma renale é o maior nematódeo já descrito que parasita animais (Mech & Tracy 2001) e também relatado em humanos (Sun et al 1986, Katafigiotis et al 2013. Os adultos têm morfologia cilíndrica, coloração vermelha e podem medir até um metro de comprimento (Monteiro et al 2002, Leite et al 2005, Alves et al 2007.…”

RESUMO A infecção em cães por Dioctophyma renale, relatada em diversas partes do mundo, é considerada incomum, na maioria das vezes. No entanto, em algumas regiões são descritos números crescentes da infecção e muitos dados da epidemiologia e do ciclo biológico do parasito ainda são obscuros. Dessa forma, o trabalho tem como objetivo descrever os aspectos epidemiológicos, clinicopatológicos e ultrassonográficos de casos de infecção por Dioctophyma renale em cães na região da Fronteira Oeste do Rio Grande do Sul. Foram estudados 28 casos de dioctofimose em cães necropsiados ou clinicamente avaliados, submetidos à ultrassonografia e cirurgia para retirada dos parasitos. Os cães errantes foram os mais acometidos e todos com possível acesso às margens do Rio Uruguai. As lesões renais e extrarrenais foram caracterizadas predominantemente por atrofia do parênquima renal com glomerulonefrite esclerosante e peritonite granulomatosa associada a parasitos adultos livres na cavidade abdominal e ovos, bem como migrações erráticas para o tecido subcutâneo. Por fim, os achados ultrassonográficos corresponderam, especialmente, a imagens transversais circulares de até 0,6 cm de diâmetro, com margem hiperecoica e centro hipoecoico. Esses achados foram patognomônicos para infecção por Dioctophyma renale, e o exame ultrassonográfico se mostrou indispensável para o diagnóstico definitivo durante a avaliação clínica. Os achados observados nesse estudo demonstram a importância dessa parasitose na região. Além disso, alertam para a importância do diagnóstico, que vem sendo subestimado, além de apontar a necessidade de mais dados acerca da epidemiologia da doença para que se chegue a métodos efetivos de controle.

Giant kidney worms in a patient with renal cell carcinoma

et al. 2016

SUMMARYDioctophyma renale (D. renale), or giant kidney worms, are the largest nematodes that infect mammals. Approximately 20 cases of human infection have been reported. We present a case of a 71-year-old man with a recent history of unintentional weight loss and painless haematuria, passing elongated erythematous tissue via his urethra. CT revealed a left renal mass with pulmonary nodules and hepatic lesions. On microscopy, the erythematous tissue passed was identified as D. renale. On subsequent renal biopsy, pathology was consistent with renal cell carcinoma. This is the first reported case of concomitant D. renale infection and renal cell carcinoma, and the second reported case of D. renale infection of the left kidney alone. BACKGROUND

“…Adult D. renale, the so-called "giant kidney worm", varies in size according to the number of the parasites present and the particular host infiltrated (Mehlhorn, 1993). Although, the parasite's natural hosts are the mustelids (Fyvie, 1971;Measures, 2001;Mech and Tracy, 2001) and ichthyophagous carnivores (Acosta et al, 2008;Ribeiro et al, 2009;Verocai et al, 2009), the nematode has been found in a great variety of carnivores, herbivores and omnivores as well as in man (Vladimova et al, 2002;Urano et al, 2001, Measures, 2001Sardjono et al, 2008;Ishizaki et al, 2010;Tokiwa et al, 2011;Katafigiotis et al, 2013;Pedrassani et al, 2014;Yang et al, 2016;Norouzi et al, 2017). In the mustelids, an extrarenal localization is rare, whereas in canines asymptomatic cases of dioctophymosis have been described with both renal and extrarenal parasite locations, as evidenced during surgery or necropsy (Pereira et al, 2006;Ferreira et al, 2010).…”

“…Extrarenal locations that have been described in canines include subcutaneous (Silveira et al, 2015), intramammary (Luna et al, 2003), subscrotal (Ortega, 1969), intragastric (Miranda et al, 1992), ovarian (Nava, 1964), intrathoracic and intra-abdominal (Morini and Grillo Torrado, 1978) tissues. In humans, D. renale is found more frequently in extrarenal locations (Beaver and Khamboonruang, 1984;Sun et al, 1986;Gutiérrez et al, 1989;Katafigiotis et al, 2013), at times resembling malignant tumors (Gu et al, 2012). In certain cases, the parasites have been identified by their renal involvement (Sardjono et al, 2008;Katafigiotis et al, 2013;Yang et al, 2016;Norouzi et al, 2017), along with one fatal case of a male with bilateral infiltration where the parasites were excreted in the urine (Venkatrajaiah et al, 2014).…”

SummaryDioctophymosis is a parasitic disease occasioned by the so-called "giant kidney worm", Dioctophyme renale, a nematode with an indirect life cycle. This parasite's definitive host is the mink, Mustela vison, though numerous wild and domestic mammals as well 1 as man can serve as final hosts. The worms also can be in ectopic locations in the body.We surveyed 692 canines by ecography, urine sampling, surgery, necropsy, and clinical examination and diagnosed 244 cases of dioctophymosis (35.3%). Of the cases of dioctophymosis identified, 30.7% were obtained by ecography, 45.9% by urinalysis, and 17.6% by both those techniques -in addition to positive findings through surgery (2.5%), necropsy (2.5%), and the spontaneous elimination of the parasites (0.8%). Cases of dioctophymosis were observed in animals as young as 4 months of age up to 15 years.The frequency of D. renale diagnosis throughout the sampling period varied significantly. There was a statistically significant association between risk factors (swimming in the river, eating frogs, fish or eels, drinking ditch water) and the prevalence of infection. It was discussed the period missing after infection in canines.
