Caracterização molecular das infecções pelos poliomavírus humanos JC e BK em pacientes renais crônicos candidatos a transplante renal no Estado do Acre

O presente trabalho investigou a ocorrência de infecção pelos poliomavírus JCV e BKV na população de pacientes com doença renal crônica, no Estado do Acre e em um grupo controle de indivíduos sem doença renal. Foram examinadas 100 amostras de urina do grupo de Pacientes e 99 amostras de urina do grupo Controle. Após a extração do DNA, a PCR foi usada para a amplificação de 173pb do gene que codifica o antígeno-T de ambos os vírus. A diferenciação entre as infecções por JCV e por BKV foi realizada por meio da digestão enzimática do produto amplificado, usando-se endonuclease de restrição. Esse estudo não identificou a presença do BKV nas amostras de urina do grupo de Pacientes e do grupo Controle. O JCV foi identificado em 11,1% (11/99) dos indivíduos do grupo Controle e em 4% (4/100) dos indivíduos do grupo de Pacientes. Foi encontrada diferença estatisticamente significante entre os grupos de Pacientes e Controle quanto à média de Uréia (p < 0,001), onde a média no grupo de Pacientes foi significantemente maior do que a média no grupo Controle. Estes resultados sugerem que os elevados níveis de uréia excretada na urina, a baixa celularidade urinária, a diminuição do “washout” (limpeza) da bexiga e o tempo para a análise das amostras, justifiquem a baixa prevalência de infecção encontrada no grupo de pacientes renais crônicos; pois esses fatores podem diminuir a quantidade de vírus na urina ou podem atuar como inibidores da PCR. Esse estudo sugere a necessidade de aumentar a sensibilidade dos testes para a identificação desses vírus.

Ultrasound analysis of a canine patient with renal disease and chronic liver disease undergoing treatment with intravenous stem cells

With the improvement in quality of life of animals, it is increasingly frequent clinical care of elderly patients, which present renal disorders, including chronic renal failure. Recent studies report the use of stem cells to treat renal failure, which would improve the levels of urea and creatinine, and in renal ultrasound evaluation. With the present work, the idea is to report a case of ultrasonographic evaluation in a patient with chronic renal failure, liver disease and splenic nodule, which underwent stem cell therapy, where there was an improvement in the sonographic evaluation of part of the liver.

Aspectos Nutricionais na Doença Renal Crônica em Cães

It is understood by Chronic Renal Failure (CRF) or Stage IV Chronic Kidney Disease (CKD) the morbid state in which there is a substantial and irreversible loss of functional capacity, metabolic and endocrine function in both kidneys, leading to a framework of dehydration, azotemia, electrolyte imbalance, anemia, uremic syndrome, secondary hyperparathyroidism, among other conditions that make the patient's life without treatment unfeasible. An adequate nutritional support to patients with CKD at any stage aims to maintain a good clinical condition and an attempt to delay the progression of the disease. The basis of a diet for patients with CKD is the restriction in this protein being of high biological value, low-phosphorus, high energy density, fiber and antioxidants combined with a good dietary practices that allow the patient a good quality of life

Aborgadens no tratamento do cão portador de insuficiência renal crônica

Chronic Renal Failure (CRF) is the most common disease among dogs of any breed. It is the cause of high levels of morbidity and death rate in dogs. It's important to have an early diagnostic of the dogs condition and immediately start a supportive treatment for CRF. In this research we are discussing the most common types of treatment focused in reducing the progression of this disease and better quality of life for the animal with IRC

Falência renal aguda em pequenos animais

The pets, mostly dogs and cats are susceptible to a variety of situations that can lead to acute kidney failure, such as infection and intoxication, besides other common causes such as dehydration or other pre-existing diseases. The abrupt decrease in renal function in these animals characterizes a severe clinical condition and requires specialized veterinary medical care since it increases the death. Early diagnosis is an important factor for the survival of these animals and so is the appropriate treatment. New technologies on diagnosis and treatment of serious diseases in veterinary medicine have made acute renal failure successfully reversed by hemodialysis in cases where conventional therapy may not be effective. In cases like that, hemodialysis treatment may be the only chance of survival for the animals, which makes this therapy more and more important and necessary, especially in referral centers of veterinary assistance

Dexmedetomidine on renal ischemia-reperfusion injury in rats: assessment by means of NGAL and histology

Background: Ischemic acute kidney injury is a common occurrence in the perioperative period and in critical patients admitted to intensive care units. The reestablishment of blood supply may worsen injury through the ischemia-reperfusion (I/R) mechanism. We investigated the effect of dexmedetomidine on the kidneys of rats subjected to an experimental I/R model. Methods: 34 rats anesthetized with isoflurane was undergone right nephrectomy and randomly assigned to four groups: Control C (saline solution); Dexmedetomidine D (dexmedetomidine); Sham S (saline solution); Sham with Dexmedetomidine SD (dexmedetomidine). The serum levels of neutrophil gelatinase-associated lipocalin (NGAL) were measured at time-points T1 (following stabilization), T2 (ischemia), T3 (reperfusion), T4 (12 h after of I/R). The kidneys were subjected to histological examination. Results: The NGAL levels were significantly higher at T4 compared with T1. Upon histological examination, the left kidneys in groups C and D exhibited a similar extent of cell injury. Conclusion: The levels of NGAL did not indicate either protection against or worsening of kidney injury. Histological examination for acute tubular necrosis showed that dexmedetomidine did not protect the kidneys from I/R.

Morphological, immunohistochemical and molecular study of renal lesions in canine visceral leishmaniasis (CVL)

Canine visceral leishmaniasis (CVL) is an anthropozoonosis characterized by a clinically chronic progressive disease. Non lymphoid organs are also affected, especially the kidneys. Dogs with leishmaniasis usually die with renal failure despite treatment. Haematoxylin-eosin (HE) staining in kidney tissue sections has low sensitivity for parasite identification. Immunohistochemistry (IHC) and polymerase chain reaction (PCR) are efficient methods for Leishmania sp. antigen and DNA detection in cases of low parasite burden. The present study aims to identify renal lesions of CVL and correlate them with microscopic findings determined by histochemistry, IHC and PCR. Both IHC and PCR provided similar positivity for amastigote identification, 3/20 animals (15%), thus increasing detection of the parasite in renal tissues when compared with histopathologic examination. The lesion most commonly observed with visceral leishmaniasis-positive canine kidney tissue was membranoproliferative glomerulonephritis, followed by interstitial nephritis without correlation to the number of amastigotes.

Manejo da insuficiência renal aguda em cães e gatos

Acute renal failure (ARF) may be defined as a subtle loss of renal function, leading to accumulation of nitrogenated substances. Several causes may lead to the development of ARF in an animal, including severe shock, intense blood loss, hypotension, dehydration, hypovolemia, deep anesthesia and nephrotoxins. Fluid therapy remains the basis of ARF treatment in animals. Thee therapeutic objective is to normalize fluid balance, solve hemodynamic problems and promote urine production. The objective of the present study is to review the procedures to manage acute renal failure in dogs and cats.
