ABSTRACT
A dog with bilateral renal dioctophymosis presented with stage 5 acute kidney injury, weight loss, vomiting, apathy, and hematuria. Laboratory tests showed creatinine of 17.2 mg/dL and Dioctophyme renale eggs in the urine. It underwent a 30-min session of hyperbaric oxygen preconditioning at a pressure of 2 ATA. Subsequently, bilateral nephroscopy was performed, without warm ischemia, using Amplatz-type renal dilators. Five parasites were removed, three females from the right kidney, one female from the left kidney, and one male from the abdominal cavity. After surgery, the patient continued doing daily hyperbaric oxygen therapy (HBOT) sessions and clinical therapy. Postoperative care consisted of analgesics, antimicrobials, antioxidants, gastric protector and fluid therapy. Ultrasound monitoring showed a reduction in the area of renal dilation and the hematological and biochemical tests showed rapid recovery from acute kidney injury. There was no bacterial growth in the urine sample collected directly from the kidneys. The patient had an excellent clinical progression and was discharged from hospital 7 days postoperatively, with creatinine values of 2.9 mg/dL. This is the first report of the use of nephroscopy in the treatment of dioctophymosis and indicates excellent chances of cure even in severe cases of bilateral parasitosis. HBOT was shown to be an ally in the clinical therapy of patients with D. renale by helping with stabilization and postoperative recovery.
ABSTRACT
Dioctophyme renale (Goeze 1782) has not previously been reported in the pampas fox (Lycalopex gymnocercus) (Fisher 1814), the most abundant canid of southern South America. A wild adult pampas fox female was found dead due to unknown causes in Santa Fe province, Argentina. Post-mortem examination revealed three red worms measuring 10, 11 and 15 cm long, each with an approximate width of 5 mm. All of them were found free in the abdominal cavity. The worms were all male and were identified through morphological examination and molecular analysis as D. renale. No worm was found in the kidneys. This study reports the first case of dioctophymatosis in the pampas fox in Argentina, increasing the range of wild aberrant host species infected by the giant kidney worm in the Neotropical region.

Dioctophyme renale has a worldwide distribution and has been diagnosed in several wild and domestic animals as well as in humans. As numerous reports in the literature exist concerning the presence of D. renale in different animal species, as well as its diagnosis, treatment, and confirmation in new geographic areas, we reviewed existing information to contribute to the knowledge of the etiology, biology, epidemiology, pathogenesis, symptoms, diagnosis, treatment, and prevention of D. renale. Results of dioctophymosis may range from asymptomatic infection to even death of the host. Diagnosis is based on data from morphology, imaging, and antibody testing, with surgical treatment being the most effective. A high potential for infection of pets exists when there is overlap with wild parasitized animals; given common risk factors for infections in humans, D. renale should be considered as having zoonotic potential.

Background: Dioctophymosis is caused by Dioctophyma renale, a parasite known as the giant kidney worm, that canparasitize the kidneys of domestic and wild animals. There are also reports of its occurrence in humans, thus revealing itszoonotic potential. In most cases, parasitized animals are asymptomatic. This parasite can cause atrophy or destroy therenal parenchyma, although ectopic locations may occur. The diagnosis is made through ultrasonography, based on thepresence of eggs in the urine, visualization of the parasite, or during necropsy. Therefore, the aim of this work was to reportthe case of a young dog infected with D. renale and subjected to nephrectomy in the state of Mato Grosso do Sul, Brazil.Case: A 6-month-old bitch with a clinical suspicion of hydronephrosis in the right kidney was referred to the VeterinaryHospital of Anhanguera-Uniderp University in the city of Campo Grande, MS. A physical examination of the patientrevealed an alteration in the urinary system. An abdominal ultrasound, urinalysis, complete blood count (CBC) tests andbiochemical profile were ordered. The erythrogram indicated erythrocytosis resulting from dehydration and loss of bodyfluids, while enzyme levels (creatinine, urea, alanine aminotransferase [ALT] and albumin) were within normal limits.The abdominal ultrasound showed the presence of a cylindrical and rounded structure characteristic of a nematode and inthe right kidney, and loss of renal parenchyma typical of D. renale infection. A urinalysis then revealed the presence ofhelminth eggs, confirming the diagnosis. The owner was informed about the need for nephrectomy of the affected rightkidney, which showed destruction of the renal parenchyma. One adult female and one adult male parasite were removedfrom inside the kidney, measuring approximately 50 cm and 35 cm in length. The patient was successfully treated, keptin hospital for observation, and returned two weeks later for reassessment of her...(AU)

Dioctophymosis is the disease caused by Dioctophyma renale, a large nematode, popularly known as giant kidney worm, and whose definitive hosts are the domestic dog and many wild mammal species. There are some reports of maned wolf parasitism by D. renale, however, in most cases the reports are restricted to the finding of the parasite during necropsy, without clinical assessment. The present report aimed to describe the clinical-therapeutic, ultrasonographic and pathological aspects of D. renale parasitism in a free-ranging maned wolf, emphasizing the treatment with an association of doramectin, praziquantel, pyrantel pamoate, and febantel that resulted in complete elimination of the parasite.(AU)
A dioctofimose é a doença causada pelo Dioctophyma renale, um nemátodo grande, popularmente chamado de verme gigante do rim e que tem como hospedeiro definitivo o cão doméstico e inúmeras espécies de mamíferos silvestres. Existem alguns relatos do parasitismo do lobo-guará por D. renale, contudo, na maioria das vezes, os relatos se restringem apenas ao achado do parasita durante a necropsia, sem a correlação clínica. O presente relato objetiva descrever os aspectos clínico-terapêuticos, ultrassonográficos e patológicos do parasitismo por D. renale em um lobo-guará de vida livre, enfatizando o tratamento com uma associação de doramectina, praziquantel, pamoato de pirantel e febantel, o que resultou na eliminação completa do parasita.(AU)

Dioctophymatosis is caused by the giant kidney worm Dioctophyme renale which occurs in dogs, cats, and wild mammals. In Brazil, the disease has been diagnosed in dogs from several states around the country. In the present study, the occurrence of D. renale larvae in snakes from southern of Brazil is reported. Three specimens of Philodryas patagoniensis (Serpentes: Dipsadidae) (common names in Brazil: parelheira, papa-pinto) roadkill in the county of Capão do Leão, State of Rio Grande do Sul, southern Brazil, were necropsied. Two third-stage larvae of D. renale were found in the coelomic cavity of P. patagoniensis. This study reveals a new host for D. renale larvae in the southern region of the State of Rio Grande do Sul, Brazil. This particular geographic area of the country has stood out as several cases of D. renale infection have been reported in a number of vertebrates from this region including domestic dogs and cats and wild animals such as carnivores, fish, and freshwater turtles.(AU)

Dioctophyme renale is a zoonotic nematode that parasites the kidneys of wild and domestic carnivores, and it has been reported frequently in Brazil. The aim here was to register the number of cases of dogs and cats diagnosed with dioctophymosis by necropsy (1981 to 2014) and ultrasound examination (2010 to 2015) in Pelotas-RS. In this context, a survey was conducted on dioctophymosis cases diagnosed at the Veterinary Pathology Laboratory (LPV) and Veterinary Clinical Hospital (HCV) of the Federal University of Pelotas (UFPel), and at a specialist veterinary imaging diagnostics clinic. In total, 95 cases were registered. The high series of the disease in dogs can be related to the presence of a large number of stray and semi-domestic dogs in the city, and also due to the ingestion of intermediate hosts of D. renale parasitized with the infective larvae. Thus, it can be concluded that Pelotas is a city with favorable conditions for the occurrence of dioctophymosis with high rate of disease in recent years.(AU)

Nesse contexto, foi realizado um inquérito de casos de dioctofimatose em animais de companhia no Laboratório de Patologia Veterinária (LPV) e no Hospital de Clínicas Veterinária (HCV) da Universidade Federal de Pelotas (UFPel), e em uma clínica veterinária especializada em diagnóstico por imagem, totalizando 95 casos registrados. A elevada casuística da doença em cães pode estar relacionada à presença de um grande número de cães errantes e semi-domiciliados na cidade, e também devido à ingestão dos hospedeiros intermediários de D. renale parasitados com a larva infectante. Assim, conclui-se que Pelotas é uma cidade propícia para a ocorrência de dioctofimatose, com elevada casuística da doença nos últimos anos.(AU)

Dioctophyme renale is a nematode that can be found parasitizing the kidney, peritoneal cavity and, rarely, other organs of canids and mustelids. This disease has high occurrence in the municipality of Três Barras, state of Santa Catarina, thus making this an interesting area to study the epidemiological aspects of infection by D. renale in dogs. Among 197 dogs, 14.2% showed the parasite eggs in urine and 16.4% showed IgG antibodies anti-D. renale in serum samples according to the indirect ELISA method; among seropositive dogs, 15 (37.5%) animals did not show any parasite eggs in their urine. Parasitism was more frequent in females, and there was no finding of interference from age on parasitism. Factors such as water potential and presence of paratenic hosts in the studied region were reported by the owners of dogs and may have contributed to the occurrence of parasitism.(AU)

ABSTRACT
O lobo-guará (Chrysocyon brachyurus) é o maior canídeo da América do Sul, sendo classificado como quase ameaçado de extinção pela União Internacional para a Conservação da Natureza e dos Recursos Naturais e como uma espécie vulnerável pelo Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis. A espécie possui área de vida extensa, ocorrendo inclusive em áreas onde conflitos entre animais silvestres e populações humanas podem acontecer. Sabe-se que o lobo-guará pode ser infectado por diversos parasitas. Neste estudo, é apresentado um novo registro do verme gigante renal (Dyoctophyma renale Goeze 1972) encontrado em lobo-guará, no estado de Goiás. Esse parasita já foi encontrado em outros estados brasileiros, sendo associado a taxas de mortalidade em populações de lobo-guará. A ocorrência desse parasita no estado de Goiás é uma informação crucial para avaliar tanto a distribuição geográfica quanto a influência potencial desse parasita na sobrevivência do lobo-guará no Brasil.

The maned wolf (Chrysocyon brachyurus) is the largest canid of South America and is classified as Near Threatened by International Union for Conservation of Nature. This species has a large home range and often occurs in areas where human-wildlife conflicts are likely to take place. The maned wolf has been previously shown to be infected by a diversity of parasite species. Here we present a new record of the giant kidney worm (Dyoctophyma renale Goeze 1972) in the maned wolf found in the State of Goiás, central Brazil. This parasite has been also found in other Brazilian states and has been shown to be linked to C. brachyurus mortality rates. The occurrence of this parasite in the State of Goiás is a crucial piece of information for evaluating the distribution as well as the potential influence of this parasite on the plight of the maned wolf in Brazil.
