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...

Abstract This study aimed to verify the occurrence of Dioctophyme renale in stray dogs in the city of Pelotas, in the state of Rio Grande do Sul, Brazil. The Laboratório Regional de Diagnóstico of the Universidade Federal de Pelotas received 146 wandering dogs for necropsy, sent by the City Hall of Pelotas from March 2012 to January 2020. Among the necropsied animals, seventeen dogs (11.64%) were diagnosed with dioctophymosis. Among these dogs, 11 were parasitized with one specimen in the right kidney, two dogs presented two specimens in the right kidney, and in other two dogs, the parasites were in the abdominal cavity. In one dog, two parasites were found in the left kidney; in another dog, both kidneys were parasitized, with two parasites in the right kidney and one in the left kidney. The data obtained in this study showed that the occurrence of D. renale in stray dogs in the city of Pelotas is high, and D. renale mainly parasitizes the right kidney.

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)

Resumo

Dioctophymosis is caused by Dioctophyme renale, a nematode that usually affects the right kidney of carnivores. The aim of this study was to report on a case of a dog with progressive weight loss and swollen abdomen that was diagnosed as presenting dioctophymosis. The patient underwent surgical treatment through which 34 nematodes were found, of which 18 were female and 16 were male, with a maximum length of 74 centimeters. The parasites were free in the abdominal cavity and inside the right kidney, and had caused peritonitis, free fluid, severe adherences between the abdominal organs and renal perforation. Parasitic diseases with a high number of specimens of this species are uncommon in dogs. The disease progresses with an inflammatory reaction and consequent formation of adherences and granulomatous tissue. This surrounds the eggs that were eliminated in the abdominal cavity by the free parasites. This disease occurs frequently in the city of Pelotas, Rio Grande do Sul, Brazil, where the patient of this report was living. To the best of authors knowledge, this is the case with the largest number of specimens of D. renale removed from a single dog in vivo.(AU)


A dioctofimose é causada por Dioctophyme renale, um nematódeo que geralmente afeta o rim direito de carnívoros. Este trabalho objetivou relatar o caso de um cão, com perda de peso progressiva e abaulamento abdominal, diagnosticado com dioctofimose. O paciente foi submetido a tratamento cirúrgico, o que permitiu o achado de 34 nematódeos, sendo 18 fêmeas e 16 machos, com tamanho máximo de 74 centímetros. Os parasitos encontravam-se livres na cavidade abdominal e no interior do rim direito, causando peritonite, formação de líquido livre, intensas aderências entre os órgãos abdominais e uma perfuração renal. Parasitoses com alto número de exemplares dessa espécie são incomuns em cães. Cursam com reação inflamatória, com consequente formação de aderências e tecido granulomatoso, envolvendo os ovos eliminados na cavidade abdominal pelos parasitos livres. A doença é frequente na cidade de Pelotas, Rio Grande do Sul, Brasil, área de origem da paciente afetada. De acordo com a pesquisa realizada, acredita-se que esse é o caso com o maior número de exemplares de D. renale removidos de um cão in vivo.(AU)

A dioctofimose em cães é uma doença parasitária registrada em vários estados do Brasil, incluindo o Rio Grande do Sul que afeta, principalmente, animais errantes que habitam áreas alagadas. A resolução do caso quando atinge apenas um rim é cirúrgica, sendo assim necessária à realização de anestesia geral para o procedimento de nefrectomia unilateral. Dessa forma, a busca por protocolos mais seguros que mantém a integridade renal é fundamental. O objetivo desse trabalho é relatar a anestesia para o procedimento de nefrectomia como tratamento de dioctofimose em um cão errante da cidade de Pelotas-RS. No presente caso, foi realizada medicação pré-anestésica, com acepromazina, cetamina associados amorfina, e indução com propofol. A manutenção do plano anestésico com isoflurano diluído em oxigênio a 100%, e foi ainda realizado o bloqueio epidural com bupivacaína e morfina para dessensibilização regional. Após o término do procedimento cirúrgico o paciente recebeu analgesia pós-operatória com meloxicam, tramadol e dipirona, e permaneceu na internação por 10 dias para monitoração da função renal e tratamento de doença dermatológica concomitante. O protocolo anestésico foi efetivo e sem maiores complicações, após alta médica foi levado para o canil da prefeitura, onde aguarda adoção.


Dioctophymosis in dogs is a parasitic disease registered in several states of Brazil, including Rio Grande do Sul, mainly wandering animals that live in flooded areas. The resolution of the case is only a surgical measure, so it is necessary to perform general anesthesia for the unilateral nephrectomy procedure. In this way, a search for other data that maintains the ri is fundamental. The purpose of this work is to report anesthesia for the nephrectomy procedure as a treatment of dioctosis in a wandering dog in the city of Pelotas, RS. In the present case, premedication with acepromazine, ketamine associated with morphine, and induction with propofol were performed. The maintenance of the anesthetic plan with isoflurane was diluted in 100% oxygen, and it was also performed with epidural block with bupivacaine and morphine for regional desensitization. After the end of the clinical procedure, the patient received postoperative analgesia with meloxicam, tramadol and dipyrone and remained in the hospital for 10 days to monitor renal function and the concomitant dermatology process. The anesthetic protocol was effective and without major complications, after being discharged to the health service, where it was installed.

Background: Dioctophyme renale, also known as “giant kidney worm”, is a cosmopolitan parasite, which usually affects domestic and wildlife canids in wetlands. Nephrotomy and nephrectomy are the only treatment options. Laparoscopic nephrectomy for dioctophymosis was first performed in veterinary patients in the late 90’s. Canine pyometra is one of the most frequent surgical disorder in the small animal setting. The purpose of this study was to report a case of successful one-stage laparoscopic approach for nephrectomy and ovariohysterectomy in a bitch.Case: A female stray dog, rescued from a riverside community, was presenting hematuria. Abdominal echography revealed presence of Dioctophyme renale worms within the right renal parenchyma. Moreover, the uterus was moderately filled by anechoic content. The patient was clinically stable and undergone laparoscopy. A 10-mm trocar was established at the middle third of the right flank, followed by 12-mmHg CO2 insufflation. The telescope was inserted and a giant worm was seen free within the abdominal cavity. A second 10-mm port was inserted cranial and dorsally to the first one. The parasite was retrieved using a laparoscopic Kelly forceps. A third 5-mm trocar was inserted in a classic laparoscopic triangulation port positioning. Renal artery and vein were individually triple ligated using titanium clips and then transected. The right ovarian pedicle was sequentially coagulated and transected using laparoscopic bipolar forceps. The right kidney was then dissected and detached from the abdominal wall, followed by cauterization and transection of the left ovarian pedicle. The uterus was exposed out of the abdominal cavity through the 5-mm port access. Uterine body and vessels were double ligated using polyglactin 910, with transfixating ligatures, and then transected. The opening of the retrieval bag was exposed through the cranial port site incision.[...]

Background: Dioctophyma renale is a globally occurring nematode that parasites the kidneys, and to a lesser extent, can be found in other organs or free in the abdominal cavity. Has the capacity to destroy the renal parenchyma. For the most part, parasitized animals are asymptomatic. The diagnosis is made through urinalysis and ultrasonography. However most the cases are diagnosed only at necropsy. As treatment nephrectomy of the affected kidney is the technique of choice. Therefore, the aim of this work was to report the case of a dog, seven months old, treated surgically by nephrectomy of the right kidney due to the destruction of the renal parenchyma caused by D. renale.Case: A 7-month-old Australian Cattle Dog, with a history of hematuria, was attended in a Florianópolis Veterinary Hospital. At the physical examination of the patient, no change was found, being extremely active. Abdominal ultrasonography, urinalysis, CBC and biochemical profile were requested. Abdominal ultrasonography showed the presence of cylindrical and rounded structures, with a hyperechogenic wall and a hypoechogenic center, compatible with D. renale, located in the right kidney. Urinalysis revealed the presence of D. renale eggs. The erythrogram showed mild anemia and the leukogram showed neutrophilic leukocytosis. Calcium, creatinine, alkaline phosphatase, phosphorus, alanine aminotransferase and urea dosages showed values within normal limits. As treatment, nephrectomy of the right kidney was performed by laparotomy. The kidney was presented with destruction of the renal parenchyma and a single parasite was removed from its interior, measuring 54 cm in length. Histopathological analysis of the affected kidney revealed diffuse pronounced fibrous connective tissue proliferation, increased urinary space with decreased glomerular tuft and increased glomerular to tubule ratio. The nephrectomy was curative and ceased the patient’s hematuria.[...]

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)


Dioctophyme renale é um nematódeo zoonótico que parasita principalmente o rim de carnívoros silvestres e domésticos, e tem sido relatado com frequência no Brasil. Objetivou-se registrar o número de casos de cães e gatos diagnosticados com dioctofimatose por necropsia (1981 a 2014) e exame ultrassonográfico (2010 a 2015) em Pelotas-RS. 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 é um parasito que afeta tanto animais como humanos e tem como órgão de eleição o rim direito. Relata-se o caso clínico-cirúrgico de um paciente canino com histórico de eliminação de três exemplares de D. renale pela urina e presença de parasitos no rim esquerdo e na cavidade abdominal. No Hospital de Clínicas Veterinárias da Universidade Federal de Pelotas, foram realizados exames pré-cirúrgicos, entre eles a ultrassonografia abdominal, que identificou a localização dos nematódeos, e o exame de Doppler pulsado dos vasos intrarrenais, que demonstrou aumento nos índices resistivos nas regiões avaliadas. O paciente foi conduzido para a realização de laparotomia exploratória, sendo removidos 23 parasitos da cavidade abdominal. A presença de D. renale causa graves lesões nos rins e nos demais órgãos da cavidade abdominal, sendo essencial o diagnóstico precoce e a remoção dos nematódeos para recuperação do paciente.(AU)


Dioctophyme renale is a parasite that attacks animals as well as humans and has the right kidney as a preferred target organ. This document reports the case of a clinical-chirurgical canine patient with a history of elimination of three D. renale samples through its urine and presence of parasites at its left kidney and abdominal cavity. Pre-cirurgical exams were performed at the Veterinary Hospital of the Federal University of Pelotas. Among these exams, abdominal ultrasonography identified the nematode's location and the Pulse-Doppler of the intrarenal vessels showed an increase in the resistive indices of the evaluated areas. An Exploratory Laparotomy was conducted with the patient who had 23 parasites removed from its abdominal cavity. The presence of D. renale causes severe lesions at kidneys and other organs of the abdominal cavity, for this reason early diagnosis and nematode´s removal are essential for the patient's recovery.(AU)

This study reports a case of parasitism by Dioctophyme renale in a supernumerary kidney and abdominal cavity of a female cat in Brazil. The three-year-old cat of indeterminate breed presented abdominal distension and was taken to the University of Contestado Veterinary Hospital in Canoinhas, state of Santa Catarina, since the owner suspected pregnancy. An ultrasound scan did not confirm pregnancy but revealed parasitism in the kidney. This case is worth reporting because domestic cats are rarely hosts of this nematode species.


Relata-se um caso de parasitismo por Dioctophyme renale em rim supranumerário e em cavidade abdominal de um gato do Brasil. Uma fêmea adulta, não castrada, sem raça definida e com aproximadamente três anos de idade, foi encaminhada ao Hospital Veterinário da Universidade do Contestado, em Canoinhas-SC, com aumento de volume abdominal e o proprietário suspeitava de gestação. Após ultrassonografia foi descartada a gestação e foi detectado parasitismo em rim. Como gatos domésticos são considerados hospedeiros incomuns desse parasita, relata-se o presente caso.

Resumo

A dioctofimose é uma parasitose causada pelo Dioctophyma renale (Goeze, 1782) de ocorrência mundial e acomete animais domésticos e silvestres. Em março de 2010, um exemplar adulto (macho) de Galictis cuja (Molina, 1782), encontrado morto por atropelamento no município de Guaíra, Paraná foi encaminhado ao laboratório de Patologia Veterinária de Universidade Federal do Paraná (UFPR), Campus Palotina, para a realização da necropsia. O cadáver apresentava bom estado nutricional e autólise moderada. Foram observados três exemplares de parasitos na cavidade abdominal, mas os rins encontravam-se preservados. Os parasitos foram fixados em formol acético e encaminhados ao laboratório de Parasitologia Veterinária da UFPR para identificação. Os exemplares coletados foram identificados como Dioctophyma renale, sendo duas fêmeas, uma com 39cm de comprimento por 4mm de largura e a outra com 16cm de comprimento por 4mm de largura e, um macho com 16cm de comprimento por 3mm de largura. O presente trabalho relata a ocorrência de parasitismo por D. renale em G. cuja na região oeste do estado do Paraná.(AU)


Dioctophymosis is a parasitic disease caused by Dioctophyma renale (Goeze, 1782) with a worldwide occurrence and affects domestic animals as well as wildlife. In March 2010, a ferret adult male, Galictis cuja (Molina, 1782), found dead by trampling in the county of Guaíra, state of Paraná, Brazil, was necropsied in the Veterinary Pathology Laboratory at Campus Palotina, Federal University of Paraná. The animal was in good nutritional condition and moderate autolysis. Three specimens of parasites were found in the abdominal cavity, but the kidneys were preserved. The parasites were fixed in acetic formaldehyde and sent to the Veterinary Laboratory of Parasitology, Campus Palotina, for identification. The parasites were identified as Dioctophyma renale, two females, one a 39cm long and 4mm wide and the other 16cm long and 4mm wide, and a male 16cm long and 3mm wide. This paper reports D. renale parasitism in G. cuja in the western of Paraná state, Brazil.(AU)

Resumo

Background: Dioctophyma renale or giant worm is a parasite that has hematophagous habits and it is found worldwide. It is most commonly observed in stray and wild domestic carnivores. It affects several wild and herbivore animals. Even though it is a zoonosis, it rarely affects humans. Its diagnosis is occasionally made during surgeries and necropsies, by the presence of eggs or the parasite itself in the urine. Its epidemiology, with a complex life cycle, starts with the eggs containing the first stage larvae, which are then ingested by its intermediate host, an aquatic oligochaete (annelid) (Lumbriculus variegatus) and the definitive host is infected by ingestion of this latter or its paratenic host, namely fish and frog. The purpose of this study was to report two Dioctophyma renale cases with different life cycles, one in the left inguinal region of a dog and the other one in an ulcerated tumor in the right I2 teat of a bitch. Case: The first case consisted of a 5-month old mongrel dog weighting 8 kg, whose owner’s main complaint was a large growth observed in the left inguinal region of the animal. No other alterations were identified at the general physical examination. An exploratory surgical procedure was immediately chosen, at which time the parasite was detected. The antibiotic prophylaxis used enrofloxacin 5 mg/kg and the pre-emptive analgesic was flunixin meglumine 1.1 mg/kg, both applied intramuscularly. Ketamine5 mg/kg associated with xylazine 2 mg/kg, administrated intravenously was used in the anesthesia, and its maintenance was made with ketamine. An incision was made to the skin, subcutaneous tissue, muscles and peritoneum in order to access the inguinal region, at which time the parasite was found. The second case was an 8-year-old mongrel bitch, not spayed and weighting 15 kg, which was taken to the Hospital of Universidade Estadual do Maranhão (UEMA), Brazil. At clinical examination, an increase in volume and the presence of an ulcer were observed in the right I2 abdominal teat. Based on this, regional mastectomy was indicated for T3, I1 and I2. The hemogram did not reveal any important alterations. The antibiotic prophylaxis used benzathine penicillin 40 mg/kg and the pre-emptive analgesic was flunixin meglumine 1.1 mg/kg, applied intramuscularly. Ketamine5 mg/kg associated with diazepam 0.5 mg/kg, administrated intravenously, was used for the induction of anesthesia. The anesthesia was maintained with halothane in a semi-closed circuit. An elliptical incision was made to the medium caudal line, with dilatation and ligation of the mammary artery, followed by removal of the teats. After surgery, the parasite was found upon incision of the part removed. During the entire transoperative procedure, the animals received 10 mL/ kg Ringer Lactate/hour. Discussion: The identification of the parasite was based on its morphological characteristics, particularly regarding size and color. The surgical findings were accidental. The parasite is identified during necropsy or when its eggs are found in urine, or when the parasite itself is eliminated. Excretory urography and ultrasound do not reveal the parasite, but they may indicate a renal dysfunction. Several parasites can be found in the same host. Only one female and one male were observed in each of the cases. The most efficient treatment is the surgical removal of the parasite and, in some cases, nephrotomy and nephrectomy are also indicated. The patients fully recovered from the condition. Organs must always be observed in procedures involving or not cavities.

Resumo

A dioctofimose é uma afecção pouco comum em cães, causada pelo Dioctophyma renale, que ocorre com maior frequência em animais errantes. Quando um único rim é parasitado, os pacientes podem não apresentar sinais clínicos devido à compensação pelo rim contralateral. Não havendo terapia clínica efetiva para a dioctofimose, o tratamento indicado é a nefrotomia ou nefrectomia, na dependência da gravidade da lesão. Foi atendido no Hospital Veterinário da Universidade de Passo Fundo (UPF) um canino, fêmea, castrado, sem raça definida, com aproximadamente um ano e pesando 12 kg, proveniente de um abrigo de animais de rua da cidade de Passo Fundo (RS), apresentando hematúria e emagrecimento progressivo há 30 dias. Através dos exames complementares realizados, foi constatado parasitismo do rim direito por D. renale. O presente relato descreve o emprego alternativo da nefrectomia videolaparoscópica como um método seguro e efetivo para o tratamento de dioctofimose em um cão e os meios utilizados para o diagnóstico.


Dioctophymosis is a less common disease in dogs caused by Dioctophyma renale, which occurs more frequently in stranded animals. When there’s only one kidney affected, there may not be detectable symptoms because there’s compensation by the other healthy kidney. Since there is no effective clinical therapy for dioctophymosis, nephrotomy or nephrectomy are the two proposed treatments, depending on the severity of the lesion. A one-year-old spayed female mongrel dog weighing 12 kg was referred to the Veterinary Hospital at the University of Passo Fundo (UPF), brought from an animal shelter at the City of Passo Fundo, RS, Brazil, presenting hematuria and progressive weight loss for about 30 days. Complementary examination showed evidences of parasitism of the right kidney by D. renale. This report describes the alternative use of videolaparoscopic nephrectomy as a safe and effective method in the treatment of dioctophymosis in a dog and the means utilized for diagnosis.
