Biliary neoplasms are uncommon in cats and affect older animals. A 12-year-old female crossbreed cat showed prostration, lethargy, apathy, and severe jaundice. Ultrasonography showed distention of the gallbladder associated with severe obstruction of the bile ducts with thickening of the biliary wall, forming amorphous masses of irregular contour and heterogeneous appearance directed to the lumen measuring up to 2 cm. Necropsy showed a gallbladder with a yellowish and soft nodule measuring 3 × 3 cm, compressing the extrahepatic bile duct, occluding the passage of bile. There were also firm, yellowish multifocal to coalescing nodules in the liver, ranging from 0.5 to 1 cm, affecting 10% of the organ, in addition to lungs with firm, yellowish multifocal nodules ranging from 0.2 to 0.5 cm, affecting 20% of the organ. Histologically, gallbladder and bile ducts had malignant epithelial neoplastic proliferation, which was organized into multiple papillary and ductal projections, separated by moderate fibrovascular stroma compatible with gallbladder adenocarcinoma. The liver and lungs also contained neoplastic structures with a ductal appearance and papilliform projections identical to those observed in the gallbladder. The immunohistochemical examination (IHC) showed intense positive staining of epithelial neoplastic cells for pan-cytokeratin (AE1/AE3) and no staining for vimentin (Clone V9). The diagnosis of gallbladder adenocarcinoma with metastasis in the liver and lungs was established based on the clinical, macroscopic, histopathological, and immunohistochemical findings.(AU)

Background: Despite being rare in domestic animals, pancreatic adenocarcinoma is the most common malignant tumor of the feline pancreas. Due non-specificity of clinical signs in cats and the late diagnosis of the neoplasm, it is necessary to understand this disease better, to contribute for the knowledge of its early recognition and treatment. Thus, this study aims to report a case of metastatic pancreatic ductal adenocarcinoma in a cat, focusing on the main clinical aspects, diagnosis, and prognosis of this disease, in addition to the description of the presentation of peritoneal carcinomatosis. Case: A 14-year-old male neutered mixed breed cat, was referred to the Feline Medicine Service (MedFel) of the Hospital de Clínicas Veterinárias (HCV) - Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, RS, with a history of hyporexia, constipation and increased abdominal volume for 3 days, besides mild difficulty in locomotion and progressive weight loss in the last 6 months. On the physical examination, the patient was alert, with a body condition score of 6/9; muscle condition score 1/4 and moderate dehydration of 7%. Popliteal lymph nodes were enlarged, and abdominal distension was evident. Around 200 mL of a slightly cloudy, straw-yellow liquid were drained from the abdominal cavity. After draining the fluid, a new abdominal palpation was performed, and there were fecal retention and a palpable mass in the right hypogastric region. The result of the cytological analysis of the fluid was consistent with a protein-rich transudate, suggesting neoplastic effusion of epithelial origin. Hematological and biochemical changes included leukocytosis due to neutrophilia, monocytosis, lymphopenia, thrombocytosis and azotemia. On abdominal ultrasound, the patient had free fluid in the abdominal cavity, and the gallbladder had discreet of biliary sludge. The intestines showed some corrugated segments with other segments lacking definition of its layers, and without peristaltic movements, suggesting intestinal neoplasia. Pancreas and adrenals were not visualized. On the chest X-ray, moderate opacification of lung fields with a diffuse interstitial pattern was observed, suggesting lung metastasis. The patient presented an acute worsening of the clinical condition and the owner requested euthanasia. The patient was referred for necropsy and based on the macroscopic and microscopic changes, the post-mortem diagnosis was metastatic pancreatic ductal adenocarcinoma with peritoneal carcinomatosis. Discussion: The clinical presentation of cats with exocrine pancreatic neoplasia is nonspecific, as clinical signs are common to several diseases, such as anorexia, vomiting, abdominal pain, weight loss with normal appetite, jaundice, depression, and lethargy. Complementary blood tests also do not provide data that could lead to the suspicion of pancreatic neoplastic disease. In the present case, the diagnosis of metastatic pancreatic ductal adenocarcinoma with peritoneal carcinomatosis was only possible post mortem. The pancreas is a difficult organ to assess adequately using most diagnostic imaging methods, so histopathology is still the method of choice for differentiating pancreatic tissue comorbidities. Therefore, exploratory laparotomy should be instituted to provide tissue samples from the pancreas and its metastases for histopathological diagnosis, whenever ultrasound or other imaging methods indicate suspicious abdominal changes. The literature reports that less than 10% of affected cats treated with complete surgical removal of the mass and chemotherapy alone will survive more than a year, and the average time for untreated cats is only 6 days. The prognosis of this disease is bad and most cats are euthanized, due to rapid clinical worsening. Therefore, diagnosis is essential to determine an adequate prognosis in advanced cases and to support therapeutic decisions or euthanasia.

Background: Trypanosoma evansi is the most common protozoan in tropical and subtropical regions of the world, due to its ability to maintain and be transmitted by vectors such as Stomoxys spp. and Tabanus spp. This protozoan causes high morbidity and mortality rates in horses in African, American and Asian countries. In the years 2021 and 2022, a high mortality rate was reported among horses with symptoms associated with Trypanosoma spp. in the municipality of Arauca, department of Arauca, Colombia. The investigation described here was therefore carried out, seeking to identify the pathogens and risk factors that led to the death of the horses in this region of Colombia. Cases: Blood samples were collected from Colombian criollo horses and dogs, as were samples of ticks, flies and horseflies that infested the horses. A variety of tissue samples were removed from the horses a few min after their death for histopathological analysis. Two questionnaires were applied to obtain information about the horses and the environment in which they live. The results of the clinical examination revealed pale mucous membranes, jaundice, high fever, dehydration and lethargy. The horses were also infested with Amblyomma mixtum (17.6%) and Dermacentor nitens (82.4%) ticks, and with Tabanus pungens (74%), Tabanus spp. (26%), and Stomoxys calcitrans flies (100%), while the dogs were infested with Rhipicephalus sanguineus s.l. (77.7%) and Amblyomma mixtum (22.2%) ticks. The blood smear test results revealed the presence of Trypanosoma spp. in 66.6% (n = 4) of the horse blood samples, and in 50% (n = 1) of the dog blood samples. PCR performed to identify the Trypanosoma species confirmed the presence of T. evansi. Histological examination of the spleen revealed the involvement and dissemination of T. evansi in the tissues. The horses also showed the presence of Equine Infectious Anemia Virus (EIAV). Discussion: This is the first updated specific report of T. evansi in criollo horses in the savannah flood zone of the municipality of Arauca, Colombia. The main risk associated with T. evansi infection in horses was found to be infestation with the natural vector T. pungens and the mechanical vector S. calcitrans, which are efficient ectoparasites for the transmission of this parasite. The presence of T. evansi in dogs represents a constant risk to horses, because dogs may serve as a reservoir for the maintenance of the hemoparasite in the population under study. Another risk factor for horses could be the presence of vampire bats (Desmodus rotundus), a species of bat that has been described as a vector and reservoir of T. evansi in Colombia. The presence of EIAV antibodies in the horses under study can be attributed to the exposure of sick horses to vectors of this virus, such as Tabanus spp., S. calcitrans and inanimate needle-shaped fomites. This is the first study that identifies the coinfection of T. evansi and EIAV in horses in the floodplain region of Colombia. In view of the importance of these 2 pathologies to the health of horses, a greater number of tests and a larger animal population will be required to determine if this coinfection is the cause of the death of criollo horses in this region of Colombia. Lastly, the owners reported that pharmacological control with trypanocides has not been successful in most of the outbreaks that occurred during the years 2021 and 2022. This may suggest that Trypanosoma evansi is developing resistance to these drugs; therefore, specific studies will be required in the future to test this hypothesis.

A icterícia é considerada como a pigmentação amarelada de regiões corpóreas como esclera, pele e mucosas. É uma manifestação presente em variadas doenças e pode ser classificada em icterícia pré-hepática, hepática ou pós-hepática. A categorização dos tipos de icterícia e suas identificações são fundamentais para que haja um maior conhecimento acerca do seu local de ocorrência, da sua gravidade e progressão. A condição pode ser observada em cães e gatos, e cada tipo pode estar associado a doenças distintas como processos hemolíticos, doenças hepatocelulares, obstruções de fluxo biliar, dentre outros. O diagnóstico da manifestação pode ser determinado por meio dos dados coletados na anamnese, exame clínico e/ou complementar, este último mediante necessidade. O tratamento varia e depende da causa base que esteja associada como terapias medicamentosas a intervenções cirúrgicas.

ABSTRACT Infectious agents cause serious diseases in humans worldwide and are responsible for the high rate of morbidity and mortality. The prevalence and epidemiology of infectious disease (HCV) in the hospital visited patients referred by the physicians through the initial findings and their associated risk factors were studied in Swat. The data of 174 infected patients were collected during the period of 2015 to 2017 from two clinical laboratories of Tehsil Matta Swat. Inform consent form was taken before blood collection. After taking informed consent blood samples were collected and ICT test was performed and then ICT positive cases were conform through PCR. A total of 174 ICT positive samples [106 male and 68 females] were included in this study. Age was considered from 10 to 72 years. Of the 174 ICT strip positive, 99 [63 males, 36 females] were confirmed through PCR. The prevalence rate was recorded 56.89%. I.V/I.M injection was recorded in 100% of the individuals. Visits to the barber shop was reported in (58%) of the individuals, married individuals were (81.0), surgical operation was reported in (44.8%), sharing toothbrush was observed in (29.9%), piercing was reported in (39.7%), family history was reported in (26.4%), dental treatment was observed in (21.8%), jaundice were (13.2%) and tattooing was (1.7%). Blood transfusion, surgical operations, Jaundice, family history and dental treatment were found significant risk factors for acquiring HCV infection. It was concluded that proper implementation of precautionary measures should be needed to control the spread of HCV in far near future.

Bacillary hemoglobinuria (BH) is a histotoxic infection caused by Clostridium haemolyticum that affects mostly cattle parasitized with trematodes. The aim of present study was to describe an atypical case of BH in a cow without access to flooded areas and without parasitism by Fasciola hepatica. After eight days of sternal decubitus and apathy, a Nellore cow was euthanized and necropsied. During postmortem examination, mild jaundice, black urine and multifocal lesions in the liver were observed. Histopathology revealed multifocal coagulation foci of necrosis in liver and basophilic bacillary structures, which were confirmed as C. haemolyticum by bacterial isolation, PCR and sequencing techniques. This is the first description of BH in cattle in Minas Gerais state, Brazil and highlight the need for of inclusion of BH as differential diagnosis even in animals not parasitized by trematodes.(AU)

Caroli syndrome is characterized by a combination of intrahepatic biliary ductal ectasia and congenital ductal fibrosis due to the failure of involution of ductal plates and large intrahepatic ducts. This study aims to report Caroli syndrome in a dog, with emphasis on clinical characteristics, complementary examinations, and diagnostic approach. A 1-year-old mixed-breed intact male dog was presented with a 7-day history of acute vomiting and anorexia. Clinical evaluation revealed severe jaundice, abdominal pain, dehydration, lethargy, and abdominal distension. Ultrasonography revealed hepatic cysts filled with fluid. Exploratory laparotomy was performed to clarify the imaging findings; however, the dog died shortly after surgery. Postmortem examination revealed that the liver was reduced in size and had multiple interconnected and distended saccular dilations. The bile ducts were markedly dilated and replaced a large part of the liver parenchyma. Multiple small cysts were also observed in the kidneys. Microscopically, the hepatic lesions were characterized by extensive bridging fibrosis associated with proliferating and ectatic bile ducts contiguous with the biliary tree. Marked fibrosis and small cysts were observed in the kidneys. Therefore, a final diagnosis of Caroli syndrome was made. While uncommon, this syndrome should be considered as a differential diagnosis for young dogs with biliary cysts and hepatic fibrosis.


A síndrome de Caroli é caracterizada pela combinação de ectasia biliar intra-hepática e fibrose ductal congênita, que se devem a falha na involução das placas ductais dos grandes ductos intra-hepáticos. Esse trabalho tem a intenção de reportar um caso de síndrome de Caroli em um canino, com ênfase em suas características clínicas, exames complementares, e abordagem diagnóstica. Um canídeo de um ano de idade, sem raça definida, apresentou um histórico clínico de sete dias de vômito agudo e anorexia. A avaliação clínica revelou severa icterícia, dor abdominal, desidratação, letargia e distensão abdominal. A ultrassonografia foi sugestiva de cistos hepáticos preenchidos por fluido. Uma laparotomia exploratória foi realizada para esclarecer os achados de imagem, porém, o cão morreu logo após a cirurgia. O cão foi submetido a exame de necropsia, onde se observou fígado diminuído em tamanho e com múltiplas dilatações saculares distendidas e interconectadas entre si. Os ductos biliares estavam acentuadamente dilatados e substituíam grande parte do parênquima hepático. Nos rins, múltiplos pequenos cistos eram observados. Microscopicamente as lesões hepáticas eram caracterizadas por extensa fibrose em ponte, associada a ductos biliares ectáticos e proliferados, que eram contíguos a árvore biliar. Nos rins, marcada fibrose e pequenas formações císticas foram observadas. Baseado na associação dos achados clínicos e patológicos, o diagnóstico de síndrome de Caroli foi feito. Mesmo que incomum, essa síndrome deve ser considerada como um diagnóstico diferencial para cães jovens com ductos biliares císticos e fibrose hepática.

Resumo

A platinosomose é uma importante enfermidade hepatobiliar parasitária que acomete felinos, sendo eles de vida livre ou semi domiciliados. O agente etiológico é o trematódeo Platynosomum spp. E a doença é popularmente conhecida como "envenenamento por lagartixa". As manifestações clínicas da platinosomose são inespecíficas assim como é incomum a observação de lesões hepáticas, o que dificulta o diagnóstico. Felinos possuem o hábito de caça e ao ingerir esses pequenos invertebrados, podem dar continuidade ao ciclo da platinosomose, uma vez que esses animais são os hospedeiros definitivos deste parasito. Esse trematódeo se aloja com frequência no trato biliar dos gatos, causando lesões e possível obstrução do ducto biliar. O grau de comprometimento das lesões hepáticas está na dependência tanto da imunidade, quanto da carga parasitária do animal. O diagnóstico de eleição é o exame parasitológico de fezes, embora ainda seja considerado pouco sensível, sendo relevante a utilização de outras ferramentas diagnósticas. O exame ultrassonográfico permite a observação de alterações hepáticas e até mesmo do próprio parasito no interior do ducto biliar, contribuindo para elucidação dessa enfermidade. Foi atendido no Hospital Veterinário "Luiz Quintiliano de Oliveira", um felino com histórico de icterícia, e ao exame clínico observou-se escore corporal magro e desidratação em 8%. Após avaliação clínica do animal, o mesmo foi encaminhado para o setor de Diagnóstico por Imagem para avaliação ultrassonográfica abdominal, durante o exame visibilizou-se aumento das dimensões hepáticas, edema de parede em vesícula biliar e a presença pequena de estrutura filiforme, hiperecogênica, em seu interior.(AU)


Platinosomiasis is an importante parasitic hepatobiliary disease that affects felines, whether they live freely or semi-domiciled. The etiological agent is the trematode Platynosomum spp. And the disease is popularly known as "lizard poisoning". The clinical manifestations of platinosomiasis are non-specific and the observation of liver lesions observed are, which makes the diagnosis difficult. Felines have a hunting habit and by ingesting these small invertebrates, they can continuing the platinosomiasis cycle, since these animals are the definitive hosts of this parasite.This trematode frequently lodges in the biliary tract of cats, causing injury and possible obstruction of the bile duct. The degree of involvement of liver lesions is in dependence on both immunity and the parasite load of the animal. The diagnosis of choice is the parasitological examination of feces, although it is still considered not very sensitive, and the use of other diagnostic tools is relevant. The ultrasonographic examination allows the observation of hepatic alterations and even the parasite itself inside the bile duct, contributing to the elucidation of this disease. He was treated at the "Luiz Quintiliano de Oliveira", a feline with a history of jaundice, and the clinical examination showed a lean body score and dehydration of 8%. After clinical evaluation of the animal, he was referred to the Diagnostic Imaging Department for abdominal ultrasonography evaluation, during the exam it was seen an increase in the hepatic dimensions, edema of the gallbladder wall and the small presence of a filiform, hyperecogenic structure inside.(AU)


La platinosomosis es una importante enfermedad parasitaria hepatobiliar que afecta a los gatos, ya sean de vida libre o semi-domiciliados. El agente etiológico es el trematodo Platynosomum spp. Y la enfermedad se conoce popularmente como "envenenamiento por gecko". Las manifestaciones clínicas de la platinosomosis son inespecíficas y la observación de lesione hepáticas es poco frecuente, lo que dificulta el diagnóstico. Los felinos tienen el hábito de la caza y al ingerir estos pequeños invertebrados pueden continuar el ciclo de platinosomosis, ya que estos animales son los hospedadores definitivos de este parásito. Este trematodo se aloja con frecuencia en el tracto biliar de los gatos, provocando lesiones y posible obstrucción del conducto biliar. El grado de afectación de las lesiones hepáticas depende tanto de la inmunidad como de la carga parasitaria del animal. El diagnóstico de elección es el examen parasitológico de heces, aunque todavía se considera insensible, siendo relevante el uso de otras herramientas diagnósticas. El examen ecográfico permite la observación de alteraciones hepáticas e incluso del propio parásito fuera de la vía biliar, contribuyendo al esclarecimiento de esta enfermedad. Un felino con antecedentes de ictericia, fue atendido en el Hospital Veterinario "Luiz Quintiliano de Oliveira", y el examen clínico mostró un índice corporal magro y deshidratación en 8%. Después de la evaluación clínica del animal, se derivó al sector de Diagnóstico por Imagen para evaluación de ecografía abdominal, durante el examen se observó aumento de las dimensiones hepáticas, edema de la pared vesicular y pequeña presencia de una estructura filiforme hiperecogénica em su interior.(AU)

Resumo

Capillaria hepatica é um nematódeo hepatotrópico da família Capillariidae, que acomete principalmente roedores, os quais são considerados reservatórios, podendo infectar também, com menor frequência, cães, gatos e o homem, pois possui potencial zoonótico, sendo responsável pela capilariose hepática. A infecção verdadeira ocorre através da ingestão de ovos embrionados infectantes liberados do fígado, após morte e decomposição do hospedeiro, por canibalismo ou por predação. A infecção espúria acorre através da ingestão de ovos não embrionados, encontrados no solo ou pela ingestão de fígado de mamíferos infectados com C. Hepatica, causando um quadro de pseudoparasitismo. Os sinais clínicos nos animais acometidos pela infecção verdadeira, podem ser inespecíficos ou associados a doença hepática como, vômito, diarreia, dor abdominal, icterícia e encefalopatias. O objetivo deste trabalho foi relatar um caso de infecção espúria por C. hepatica em canino doméstico, no município de Pelotas, Rio Grande do Sul, Brasil, diagnosticado a partir da observação de ovos do parasito em exame coproparasitológico.(AU)


Capillaria hepatica is a hepatotropic nematode of the Capillariidae family, which mainly affects rodents, which are considered reservoirs, and may also infect, less frequently, dogs, cats and humans, as it has zoonotic potential, being responsible for hepatic capillarosis. True infection occurs through ingestion of infective embryonated eggs released from the liver, after death and decomposition of the host, by cannibalism or predation. The spurious infection occurs through the ingestion of non-embryonic eggs, found in the soil or by the consumption of the liver of mammals infected with C. hepatica, causing pseudoparasitism. Clinical signs in animals affected by true infection may be nonspecific or associated with liver disease such as vomiting, diarrhea, abdominal pain, jaundice and encephalopathies. The objective of this study was to report a case of infection by C. hepatica in a domestic canine, in the city of Pelotas, Rio Grande do Sul, Brazil, diagnosed from the observation of parasite eggs in a coproparasitological examination.(AU)

La verdadera infección se produce por la ingestión de huevos embrionados infecciosos liberados del hígado, después de la muerte y descomposición del huésped, por canibalismo o depredación. La infección espuria se produce por la ingestión de huevos no embrionarios, que se encuentran en el suelo o por el consumo del hígado de mamíferos infectados con C. hepatica, provocando pseudoparasitismo. Los signos clínicos en animales afectados por una infección verdadera pueden ser inespecíficos o estar asociados con enfermedades hepáticas como vómitos, diarrea, dolor abdominal, ictericia y encefalopatías. El objetivo de este estudio fue reportar un caso de infección espuria por C. hepatica en un canino doméstico, en la ciudad de Pelotas, Rio Grande do Sul, Brasil, diagnosticado a partir de la observación de huevos de parásitos en un examen coproparasitológico.(AU)

Background: Iatrogenic gallbladder perforation during laparoscopic cholecystectomy (LC) is a common complication and occurs in at least one third of human patients undergoing LC. This is attributed to the fragility of the gallbladder wall associated with mucocele and cholecystitis, in addition to the need for repetitive gripping and traction of the gallbladder during its manipulation with laparoscopic instruments. As complications from this event are rare in human patients, conversion to laparotomy is not routinely indicated and the adverse consequences of bile spillage are minimized by abundant irrigation of the peritoneal cavity and adequate antimicrobial therapy. On the other hand, there is little information regarding the outcome of laparoscopic management of this complication in laparoscopic cholecystectomies in dogs, particularly since most surgeons indicate conversion in these cases. Thus, we describe a case of biliary peritonitis that developed in a dog after laparoscopic management of iatrogenic perforation of the gallbladder during a laparoscopic cholecystectomy, in a case of gallbladder mucocele. To the best of our knowledge, there are no reports of biliary peritonitis following laparoscopic management of iatrogenic gallbladder perforation during LC in dogs. Case: A 14-year-old Poodle was referred for clinical evaluation with selective appetite, recurrent episodes of hyporexia, and abdominal discomfort. Ultrasound findings characterized chronic liver disease and gallbladder mucocele. The patient was referred for laparoscopic cholecystectomy, during which the gallbladder was iatrogenically perforated, with extravasation of a large volume of bile content. This complication was managed by copious abdominal irrigation via laparoscopic access and antimicrobial therapy. On the second postoperative day, the patient started to present apathy, hyporexia, emesis, and jaundice. The patient remained hospitalized in the intensive care unit for stabilization and monitoring through hematological examinations and serial abdominal ultrasound. Due to progressive worsening of the clinical picture, an exploratory laparotomy was performed ten days after the initial surgical procedure. This examination showed multiple adhesions and the presence of bile residues adhered to numerous points on the peritoneal surface and pancreas. Despite the intensive treatment instituted, death occurred 10 h after the second surgical procedure. Discussion: The high risk of gallbladder perforation during laparoscopic cholecystectomies correlates with the dissection step or repetitive grasping and traction of the gallbladder with laparoscopic instruments. Conversion is not routinely indicated and laparoscopic management is considered effective in humans. However, in this case, the presence of a large volume of extravasated semisolid bile content and its adherence to the mesothelial surface made it impossible to remove it in its entirety despite the abundant irrigation of the abdominal cavity, resulting in a picture of biliary peritonitis in the postoperative period. In view of the reported negative outcome, the authors encourage the adoption of measures that minimize the risk of gallbladder perforation when performing LC in dogs. These include the use of atraumatic instruments or aspiration of bile content before surgical manipulation. Cases in which such a complication is recorded should be carefully monitored to enable early diagnosis and treatment of biliary peritonitis. Furthermore, conversion should be considered when there is extravasation of large volumes of bile, particularly in the presence of gallbladder mucocele, until future studies establish the safety and effectiveness of laparoscopic management of this complication.

ABSTRACT Purpose: To investigate experimentally the effects of Tropifexor, a farnesoid X receptor agonist, on liver injury in rats with obstructive jaundice. Methods: Forty healthy Wistar albino female rats were divided randomly in selected groups. These groups were the sham group, control group, vehicle solution group, Ursodeoxycholic acid group and Tropifexor group. Experimental obstructive jaundice was created in all groups, except the sham one. In the blood samples obtained, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin and direct bilirubin levels were established and recorded. Additionally, liver malondialdehyde, myeloperoxidase and catalase enzyme activity in the tissue samples were studied. Histopathological analysis was also performed. Results: No statistical difference was found between the control group and the Tropifexor group when AST, ALT and ALP values were compared. However, it was found that the Tropifexor group had statistically significant decreases in the values of GGT, total bilirubin and direct bilirubin (p < 0.05). Additionally, Tropifexor decreased the median values of malondialdehyde and myeloperoxidase, but this difference was not statistically significant compared to the control group. Finally, the Tropifexor group was statistically significant in recurring histopathological liver damage indicators (p < 0.05). Conclusions: Tropifexor reduced liver damage due to obstructive jaundice.

Background: Hepatic cysts are rarely described in association with infections by Platynosomum sp. Infected animals are most often asymptomatic, and the severity of symptoms is associated with the number of biliary tract parasites, which may lead to cholangitis and cholangiohepatitis. Although platinosomiasis is often associated with cholangitis and cholangiohepatitis, it rarely is with polycystic disease. For the parasite's life cycle to occur, the infected cat must eliminate the eggs in the feces and three intermediate hosts are needed: snails, terrestrial isopods and vertebrates like the frog or the gecko. The eggs are ingested by the snails, then the miracids are released and matured into the mother sporocyst form, which originates child sporocysts containing the cercariae, that leave the mollusks for the soil and are ingested by the terrestrial isopod in which the cercariae matures until metacercariae. Vertebrates ingest terrestrial isopods and are ingested by felines. The present study aimed to report an unusual case of platinosomiasis with the development of multiple hepatic cysts. Case: A mixed breed male kitten was admitted with a history of apathy, hyporexia, increased abdominal volume and jaundice. In the ultrasound examination, we could see hepatomegaly and several hypoecogenic rounded structures, similar to cysts. There was an increase of serum concentration of the hepatic enzymes alanine transaminase and gamma glutamyl transferase enzyme. The parasite's eggs were investigated in the patient's feces using the simple sedimentation method, with a negative result. The animal was submitted to celiotomy and it was possible to observe several cystic structures in the liver. The cysts content was sent to cytology and culture. Cytology result was compatible with liver cyst and there was no bacterial growth in the culture. Bile fluid was collected and sent for Platynosomum sp. research using the centrifugal sedimentation test in formalin-ether solution, which allowed the parasite's eggs to be observed. The cat was treated with praziquantel,silymarin, S-Adenosyl methionine, and ursodeoxycholic acid. The patient gradually improved from jaundice and there was a reduction in abdominal volume. Discussion: This report describes a case of platinossomiasis associated with polycystic liver disease in a domestic cat, which seems to be an uncommon presentation. Most infected cats are asymptomatic, but some animals may exhibit anorexia, apathy, increased abdominal volume due to hepatomegaly and/or ascitis and jaundice. Although infestation in domestic cats is relatively common, its association with liver cysts is rare or poorly reported in the literature, representing a diagnostic challenge, which makes mandatory the inclusion of this differential diagnosis in polycystic liver diseases in cats. The diagnosis of this parasitosis can be made based on the association among clinical signs, laboratory tests and ultrasound examination, but the definitive diagnosis is usually made by visualizing the parasite's eggs. In the case described, it was not possible to observe parasite's eggs in the patient's feces, but in the bile. Platynosomum sp. infection should always be considered as a differential diagnosis in cases of polycystic liver disease in cats, especially in countries with tropical or subtropical climate. Early diagnosis and appropriate treatment were fundamental for the improvement of the patient's clinical condition.

Background: Capillaria hepatica is a nematode, zoonotic, with worldwide distribution. The main hosts are rodents, nevertheless other mammals can be affected. Although the parasite has high affinity for the liver, it rarely causes a hepaticdisease in domestic animals and humans. The diagnosis is difficult and usually a biopsy is required. The treatment is difficult and is based in anti-helminthic and corticoid, but prevention is the best strategy against the disease. The aim of thepresent report is to describe a case of hepatic capillariosis in a dog approaching the clinical signs, diagnosis and therapeutic.Case: A 12-year-old Brazilian Terrier bitch, with a history of visit to the farm and regular hunting of rats, frogs, birds andother wild animals, was attended with hyporexia and apathy. At the physical exam the dog presented elevation of rectaltemperature, intense jaundice and abdominal pain. In the biochemical exams was noticed a slight increase in globulins anda sharp increase in alkaline phosphatase (AP), total, direct and indirect bilirubin, suggesting a liver injury. In the ultrasonographic exam, hepatomegaly with dispersed hyperechoic areas were observed, suggesting hepatic steatosis. The patientwas treated with ursodesoxicolic acid and S-adenosil metionin for 30 consecutive days, showing a clinic improvement.Two months after the end of the treatment the animal worsened, showing jaundice, ascites, motor incoordination, weakness, difficulty in food and water ingestion and changes in the mental state. In the complete blood count was observed amacrocytic hypochromic regenerative anemia, leukocytosis with neutrophilia and monocytosis and thrombocytopenia.In biochemical exams was detected decrease in creatinine and albumin and increase in alanine aminotransferase and AP,suggesting hepatopathy by biliary obstruction. There were performed exams for leishmania and ehrlichiosis that testednegative. In the ultrasonographic exam it...
