A preliminary investigation was performed to evaluate the use of a new, noninvasive technique for the localization of canine renal lesions by electrophoresis of urinary proteins. Urine specimens from six clinically healthy, nonproteinuric dogs and 12 dogs with persistent proteinuria were examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE). Urine electrophoretic patterns of proteinuric dogs were classified as glomerular (n=4), tubular (n=2), or mixed (glomerular and tubular) (n=6), based on the number and molecular weight of the silver-stained protein bands. Renal tissues from biopsies or necropsies were obtained from eight of the dogs with proteinuric disease. Interpretation of seven of eight electrophoretograms agreed with the histologic interpretation of renal lesions. We concluded SDS PAGE is a potentially valuable technique for detection and localization of renal lesions in dogs with proteinuric disease.  相似文献

Glomerular diseases are a leading cause of chronic kidney disease in dogs but seem to be less common in cats. Glomerular diseases are diverse, and a renal biopsy is needed to determine the specific glomerular disease that is present in any animal. Familial glomerulopathies occur in many breeds of dogs. However, most dogs with glomerular disease have acquired glomerular injury that is either immune-complex mediated or due to systemic factors, both of which are believed to be the result of a disease process elsewhere in the body (i.e., neoplastic, infectious, and noninfectious inflammatory disorders). A thorough clinical evaluation is indicated in all dogs suspected of having glomerular disease and should include an extensive evaluation for potential predisposing disorders. Nonspecific management of dogs with glomerular disease can be divided into 3 major categories: (1) treatment of potential predisposing disorders, (2) management of proteinuria, and (3) management of uremia and other complications of glomerular disease and chronic kidney disease. Specific management of specific glomerular diseases has not been fully studied in dogs. However, it may be reasonable to consider immunosuppressive therapy in dogs that have developed a form of glomerulonephritis secondary to a steroid-responsive disease (e.g., systemic lupus erythematosus) or have immune-mediated lesions that have been documented in renal biopsy specimens. Appropriate patient monitoring during therapy is important for maximizing patient care. The prognosis for dogs and cats with glomerular disease is variable and probably dependent on a combination of factors. The purpose of this article is to discuss the general diagnosis and management of dogs with glomerular disease.  相似文献

BACKGROUND: Oil Red O, a stain commonly used to demonstrate lipid in frozen tissue, also may be used to stain air-dried cytologic specimens. OBJECTIVE: The purpose of this study was to prospectively evaluate the value of Oil Red O in identifying lipid to aid in the differentiation of liposarcomas from other types of sarcoma. METHODS: Twelve tumor specimens from dogs were evaluated. The tumors were included in the study if initial cytologic evaluation indicated a sarcoma, and if histologic confirmation was available. Oil Red O was applied to all cytologic specimens. RESULTS: Tumor specimens were diagnosed histologically as liposarcoma (3 well-differentiated, 1 pleomorphic), hemangiopericytoma (n = 3), fibrosarcoma (n = 3), malignant fibrous histiocytoma (n = 1), and undifferentiated sarcoma (n = 1). Cytologic specimens from all liposarcomas showed strong positive staining of cytoplasmic vacuoles for lipid. Specimens from other sarcomas stained negative for Oil Red O, with the exception of weak, irregular positive staining in 1 hemangiopericytoma. CONCLUSION: Our results suggest that Oil Red O staining may be an easy, inexpensive, and useful diagnostic tool for the differentiation of liposarcoma from other mesenchymal neoplasms.  相似文献

The clinico-pathological findings are described in thirteen young dogs with advanced renal disease. All but three dogs were less than 2 years old. Some had signs of renal dysfunction since birth. Presenting signs were variable but anorexia, lethargy and weight loss were most frequent. All dogs had raised blood urea levels and most passed dilute urine; proteinuria and anaemia were variable findings. At necropsy all dogs had extra-renal lesions of renal failure and finely granular or lobulated, shrunken kidneys. The microscopical appearances of the kidneys were not those of amyloidosis, inflammatory or glomerular disease but were considered likely to be of developmental origin. The renal lesions were divided into three histologically distinct groups.
  • 1 Predominantly cystic and connective tissue changes, characterized by striking dilatation of glomerular capsular spaces and cortical tubules.
  • 2 Atypical connective tissue changes in which there were segmental bands of fibrous tissue containing primitive glomerular and tubular structures.
  • 3 Predominantly glomerular and connective tissue changes, characterized by varying degrees of glomerulosclerosis and widespread calcification of glomeruli, tubules and blood vessels.
All groups had cortical and medullary interstitial fibrosis but minimal inflammatory cell infiltrates.  相似文献

Membranoproliferative glomerulonephropathy was diagnosed in 5 of 7 adult Beagles from the same litter. Dogs were raised in more than 1 area of the United States. One died without evidence of renal disease when it was 3 years old. At 8 years of age, 2 dogs developed signs of uremia, including polyuria, polydipsia, and infrequent episodes of anorexia and vomiting. Serum biochemical variables and urine specific gravity values were consistent with renal azotemia. Both dogs had proteinuria. Although healthy, 3 of the 4 remaining Beagles had proteinuria. Of these 3, only 1 was azotemic. Membranoproliferative glomerulonephritis was diagnosed on the basis of results of histologic examination of renal biopsy specimens from 4 of the dogs. Electron microscopy performed on 3 of the renal biopsy specimens revealed identical lesions, consisting of an extremely thickened glomerular basement membrane with multilaminar splitting. Immunoglobulin or amyloid deposits were not detected. On the basis of similar clinicopathologic abnormalities, common genetic background, and identical histopathologic and electron microscopic findings, familial renal disease was diagnosed. Additional studies involving other related Beagles are needed to identify the hereditary nature of membranoproliferative glomerulonephropathy in Beagles.  相似文献

Forty dogs with canine leishmaniosis (CL) participated in this study, which was designed to investigate the effect of allopurinol on the progression of the renal lesions associated with this disease. The animals were allocated into 5 groups. Group A dogs (n = 12) had neither proteinuria nor renal insufficiency, group B dogs (n= 10) had asymptomatic proteinuria, and group C dogs (n = 8) were proteinuric and azotemic. Two more groups, CA and CB, comprising 5 dogs each, served as controls for groups A and B, respectively. Group A, B, and C dogs received allopurinol PO (10 mg/kg q12h) for 6 months, whereas group CA and CB dogs were placebo-treated. Serum biochemistry profile, urinalysis, urine protein/creatinine ratio, and glomerular filtration rate (GFR) measurements were carried out at the beginning of the study, the 3rd month, and the 6th month, whereas renal biopsies were carried out only at the beginning and the end of the trial. Membranoproliferative glomerulonephritis was the most common cause of chronic renal failure. Mesangioproliferative and tubulointerstitial nephritis were detected even in group A and CA dogs. Allopurinol not only lowered proteinuria in group B dogs but also prevented the deterioration of GFR and improved the tubulointerstitial, but not the glomerular, lesions in both group A and group B dogs. Further, it resolved the azotemia in 5 of the 8 dogs admitted with 2nd stage chronic renal failure (group C). Consequently, treatment with allopurinol is advisable in CL cases with asymptomatic proteinuria or 1st-2nd stage chronic renal failure.  相似文献

Although the nephropathy of visceral leishmaniasis (VL) is known both in humans and dogs, histopathologic alterations have not been thoroughly studied. We examined renal alterations in 55 dogs with naturally acquired VL compared with five noninfected dogs from an endemic area in northeastern Brazil. Glomerulonephritis was found in 55 dogs, interstitial alterations in 53 dogs, and tubular changes in 43 dogs with VL. The glomerular alterations found were minor glomerular abnormalities (n = 8, 14.5%), focal segmental glomerulosclerosis (n = 10, 18.2%), mesangial proliferative glomerulonephritis (n = 17, 32.7%), membranoproliferative glomerulonephritis, (n = 18, 30.9%), crescentic glomerulonephritis (n = 1, 1.8%), and chronic glomerulonephritis (n = 1, 1.8%). Morphometric and ultrastructural studies complemented the analysis. The five control animals exhibited no glomerular alterations. The glomerular lesions were related to functional alterations. Considering that the alterations of canine and human nephropathy in VL are very similar, the data obtained in this study constitute an important contribution to the understanding of canine and human VL nephropathy.  相似文献

The aim of this study was to detect Leishmania infantum DNA by real-time PCR in urine from different groups of dogs with clinical leishmaniosis. Urine from 10 clinically healthy dogs and 43 dogs with clinical leishmaniosis diagnosed by positive serology and/or bone marrow PCR were studied. The group of 43 dogs with clinical leishmaniosis was divided into three subgroups: 13 dogs with renal insufficiency and proteinuria (urine protein-creatinine ratio greater than one), 13 dogs with only proteinuria, and 17 dogs with neither renal insufficiency nor proteinuria. The detection of Leishmania DNA was performed by light cycler real-time PCR using hybridization probes in each urine sample. Leishmania positive PCR was found in 47% (20/43) of the urine from leishmaniotic dogs, while all urine from clinically healthy dogs were negative. The percentages of positive Leishmania PCR were 85% (11/13) in dogs with renal insufficiency and proteinuria, 23% (3/13) in dogs with proteinuria and 35% (6/17) in dogs with neither renal insufficiency nor proteinuria. Dogs with renal insufficiency and proteinuria presented a statistical significant greater percentage of positive Leishmania PCR in urine when compared with the other subgroups (P<0.02). This study demonstrates the presence of Leishmania DNA in urine of dogs with leishmaniosis. Those dogs with severe renal damage present a greater number of Leishmania parasites in urine.  相似文献

In 51 dogs with predominantly massive urinary protein loss, the daily loss was quantified and glomerular and tubulointerstitial lesions from renal biopsies were characterised and graded using histology, immune fluorescence and electron microscopy. The highest median daily urinary protein loss occurred in dogs with membranous glomerulonephritis (median 380 mg kg-1 d-1) and renal amyloidosis (median 257 mg kg-1 d-1). Although in nine febrile dogs the urinary protein loss was transient, both glomerular and tubular lesions were diagnosed in five and seven of these dogs, respectively. The pattern of urinary proteins was determined using sodium dodecyl-sulphate polyacrylamide gel electrophoresis. The albumin fractional clearance (FC) was raised in 46 dogs, whereas the FCS of the low molecular weight (MW) protein fraction (MW less than 66,000) and high molecular weight protein fraction (MW more than 66,000) were raised in 42 and 28 dogs, respectively. Both the high molecular weight protein FC and albumin FC significantly correlated to the grade of glomerular lesions, whereas the low molecular weight protein FC only moderately significantly correlated to the grade of tubular lesions. The selectivity index, calculated as (formula; see text) did not differentiate between the various forms of glomerulopathies. The urinary lysozyme concentration was significantly correlated to the grade of tubular lesions. It is concluded that although quantitative and qualitative measurements of urinary proteins can provide additional clinical information, they do not have a reliable predictive value and histopathological examination of renal tissue is still necessary for the final diagnosis.  相似文献

The purpose of this retrospective study was to investigate the relationship among proteinuria consisting of immunoglobulin free light chains (FLCs), renal histopathologic findings, and routine markers of renal function in 11 dogs exposed to Leishmania infantum (n = 8), Ehrlichia canis (n = 2), and Babesia canis (n = 1). FLC proteinuria was suspected based on identification of a 22- to 27-kDa band by sodium dodecyl sulfate-agarose gel electrophoresis (SDS-AGE) and later confirmed by immunofixation electrophoresis. SDS-AGE identified an isolated band of 22-27 kDa in 8 dogs, whereas the remaining 3 had a 22- to 27-kDa band and an additional band of 67-72 kDa. The median urine protein-to-urine creatinine ratio was 0.37 (range, 0.11-2.24) and increased ratios were found in 6 dogs (54.5%) (reference value, <0.7). All dogs underwent histologic examination of renal percutaneous biopsy specimens and determination of serum creatinine and urea concentrations. Tissue samples for light microscopy were stained with hematoxylin-eosin, periodic acid-Schiff, Goldners trichrome, and methenamine silver. In the study group, the glomerular tufts, mesangium, tubulointerstitium, and vessels appeared unaffected. The median serum creatinine concentration in these 11 dogs was 1.3 mg/dL (range, 0.8-1.5 mg/dL; reference range, 0.6-1.5 mg/dL), whereas the concentration for urea was 28 mg/dL (range, 22-52 mg/dL; reference range, 20-50 mg/dL). All dogs had normal renal morphology and had normal serum creatinine and urea concentrations, suggesting that immunoglobulin FLC may be detected in the urine of dogs exposed to L. infantum, E. canis, and B. canis without any apparent structural or functional renal derangement.  相似文献

Urine analysis, serum biochemical profile and a cortical wedge biopsy for histopathological examination was performed on 42 South African National Defence Force (SANDF) dogs from around the country. The only significant finding on urine analysis and serum biochemistry was a relatively large number (16/42) of dogs with elevated serum inorganic phosphate levels. Histopathology revealed that only 9 of the animals had normal kidneys reflected in the wedge biopsy material, with over 50% of them showing signs of glomerular pathology (primarily mesangioproliferative glomerulonephritis). Other conditions detected histopathologically were haemosiderosis (47% of animals), focal nephrosis (2.4%), membranoproliferative glomerulonephritis (2.4%), focal interstitial nephritis (4.7%) and acute tubular nephrosis (4.7%). The lesions observed were of limited distribution and extent; this histopathological finding may account for the absence of significant abnormalities on urine analysis or serum biochemistry profiles. It appears from these results that a large percentage of the SANDF population would be expected to have mild renal lesions, but that these lesions are not severe enough to lead to clinical signs. The findings of this study are similar to those of randomly selected populations of non-military dogs performed in other areas of the world, which also demonstrated an unexpectedly high incidence of histopathological renal pathology in dogs considered healthy. These lesions may well, however, play a role in later life, and it is recommended that military veterinarians maintain an index of suspicion for renal disease, particularly glomerular disease. The aetiology of the histopathological lesions is unknown.  相似文献

Background: Proteinuria is a feature of pyometra‐associated renal dysfunction, but its prevalence and clinical relevance are not well characterized. Objectives: To define which subset of dogs with pyometra has clinically relevant kidney injury by quantification of proteinuria; light, immunofluorescence, and electron microscopic examination of kidney biopsy specimens; and measurement of urinary biomarkers. Animals: Forty‐seven dogs with pyometra. Ten clinically healthy intact bitches of comparable age. Methods: Prospective study. Routine clinicopathological variables including urinary protein to creatinine ratio (UPC) were analyzed. Validated assays were used to quantify urinary biomarkers for glomerular (urinary albumin, urinary immunoglobulin G, urinary C‐reactive protein, urinary thromboxane B2) and tubular function (urinary retinol‐binding protein, urinary N‐acetyl‐β‐d ‐glucosaminidase). Kidney biopsy specimens from 10 dogs with pyometra and dipstick urine protein concentrations of 2+ or 3+ were collected during ovariohysterectomy. Urinalysis was repeated within 3 weeks after surgery in 9 of the 10 dogs. Results: UPC (median, range) was significantly higher in dogs with pyometra (0.48, 0.05–8.69) compared with healthy bitches (0.08, 0.02–0.16) (P < .01). Twenty‐two of 47 dogs with pyometra had UPC>0.5, 12 had UPC>1.0, and 7 had UPC>2.0. Glomerulosclerosis and tubulointerstitial nephritis were common kidney biopsy findings in proteinuric dogs with pyometra. Dogs with glomerulosclerosis (5/10), either global or focal and segmental, had UPC>1.0 at ovariohysterectomy and afterward. Dogs with structural glomerular and tubular changes mostly had urinary biomarker to creatinine ratios above the 75th percentile. Conclusion: Dogs with pyometra and UPC>1.0 or high ratios of urinary biomarkers appear likely to have clinically relevant renal histologic lesions and require monitoring after ovariohysterectomy. Future studies should evaluate the role of pyometra‐associated pathogenic mechanisms in causing or exacerbating focal and segmental glomerulosclerosis in dogs.  相似文献

Kidney specimens from 12 dogs with congenital portosystemic shunts were examined histologically. Glomerulopathy of variable severity was present in the kidney sections of all 12. Marked irregular thickening of the glomerular capillary wall was the most prominent pathological change, the renal interstitium being largely unaffected. The severity of lesions was not correlated with the age of dogs at the time of necropsy. An immunoperoxidase technique failed to demonstrate significant IgA or IgG deposition in affected glomeruli. Proteinuria was generally mild or absent despite significant glomerular lesions, except in dogs with concurrent urinary tract infection.  相似文献

This report describes an uncommon case of nonamyloidotic fibrillary glomerulonephritis. A 5-year-old female European cat was presented with nephrotic syndrome. Serum biochemistry and urinalysis revealed a mild increase in cholesterol, low total protein, severe hypoalbuminemia, and high proteinuria with a high protein-to-creatinine ratio. An histologic examination revealed an interstitial nephritis and a diffuse glomerulonephritis, with multifocal thickening of the Bowman's capsule. Transmission electron microscopy showed widespread fibrillary deposits in the glomerular basement membrane and in the mesangium. These fibrils ranged between 18 and 26 nm in diameter and were Congo red negative, which allowed their differentiation from amyloid. Immunohistochemistry demonstrated expression for immunoglobulin M (IgM) and immunoglobulin G (IgG) within the mesangium. Renal deposits of Congo red-negative amyloid-like fibrils have been described in humans, horses, monkeys, and dogs. This is the first report of noncongophilic fibrillary glomerulopathy in a cat.  相似文献

In a 10-year retrospective study, we evaluated the clinicopathologic features and renal immunofluorescence patterns of glomerulonephritis in 41 dogs. On the basis of results of histologic examinations, the dogs were segregated into 3 groups, including membranous (n = 12), mesangioproliferative (n = 15), or membranoproliferative glomerulonephritis (n = 14). No significant differences existed among groups in regard to age or duration of illness. Most dogs had been ill for one month or longer. The proportion of dogs with azotemia, anemia, and hyperphosphatemia were not different among the disease groups. Proportion of dogs with hypoalbuminemia and the severity of hypoalbuminemia were not different among groups. Highest urine protein losses and 24-hour urine protein/creatinine ratios developed in dogs with membranous glomerulonephritis. Although hypoalbuminemia and hypercholesterolemia were common (49%), the formation of edema or ascites was not (15%) and, therefore, few dogs had all of the classic features of the nephrotic syndrome. Few dogs suffered thromboembolic complications. Antinuclear antibody titers developed in 11 dogs, the highest titers developing in dogs with polyarthritis and systemic lupus erythematosis. Cellulose acetate electrophoresis detected alpha 2 and beta 1 globulin spikes in most dogs (87%). Results of renal immunofluorescence testing were positive in 36 dogs, using polyvalent antisera for immunoglobulins (Ig)G, IgA, IgM, and/or antisera for complement factor C3. When monovalent antisera for IgG, IgA, and IgM, and fibrinogen were used, immunofluorescence was not observed as often. The major fluorescent pattern was discrete multifocal segmental granular glomerular fluorescence, consistent with immune-complex deposition. Two dogs had linear glomerular staining patterns; however, antibodies directed against normal glomerular basement membrane were not found via elution studies. A high prevalence of glucocorticoid excess (treatment with glucocorticoids and spontaneous hyperadrenocorticism) (34%), chronic inflammatory skin disease (27%), neoplasia (17%), polyarthritis (12%), and systemic lupus erythematosis (7%) were observed as clinical problems concurrent with glomerulonephritis. In 5 dogs, treatment of glomerulonephritis with prednisolone (0.5 to 1.1 mg/kg) did not result in beneficial effects and in fact appeared to be detrimental, leading to azotemia and worsening proteinuria and physical condition in some of the dogs.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

OBJECTIVE: To evaluate results of SDS-agarose gel electrophoresis (AGE) of urinary proteins for use in defining glomerular and tubulointerstitial derangements, investigate patterns of high-molecular-weight (HMW) proteins for differentiating among glomerular disorders, and assess low-molecular-weight (LMW) proteins as markers of severity of tubulointerstitial disease in dogs. ANIMALS: 49 dogs with increased serum creatinine concentrations or abnormal renal protein loss. PROCEDURE: Urinary proteins were examined by use of SDS-AGE and differentiated on the basis of molecular weight. The HMW proteins (> or = 69 kd) were considered indicative of glomerular origin, whereas LMW proteins (< 69 kd) were of tubular origin. Renal specimens were examined by use of light microscopy. Glomerular and tubulointerstitial lesions were differentiated by use of the classification for the World Health Organization and semiquantitative grading, respectively. RESULTS: Sensitivity of SDS-AGE was 100% for detection of glomerular lesions and 92.6% for tubulointerstitial lesions; specificity was 40% and 62.5%, respectively. Although HMW urinary proteins were not significantly associated with the type of glomerular lesion, LMW urinary proteins were significantly associated with the grade of tubulointerstitial damage. Detection of 12- or 15-kd proteins or both was highly indicative of a severe tubulointerstitial lesion. CONCLUSIONS AND CLINICAL RELEVANCE: SDS-AGE of urinary proteins in dogs represents a noninvasive test with high sensitivity for identifying glomerular and tubulointerstitial damage, but low specificity limits its validity as a stand-alone test to differentiate between glomerular and tubulointerstitial lesions. The test is particularly useful for identifying dogs with advanced tubulointerstitial disease but cannot be used to characterize glomerular disorders.  相似文献

A study was made of the nephropathy in canine leishmaniasis produced in ten adult dogs naturally infected with Leishmania infantum. Renal function analyses were performed (uraemia, creatinaemia, plasma proteins, biochemistry and urinary sediment), the humoral immune response (fluorescent antibodies and levels of serum IgG, IgM and IgA) was assessed and histopathological studies were carried out. Correlation of the results showed acute renal insufficiency which was reversible in two animals (endotheliomesangial glomerulonephritis) and irreversible in four cases corresponding to glomerulonephritis in its Type I and Type II proliferative forms; extensive increase in the glomerular basal membrane, proliferation of mesangial cells and growth of the mesangial matrix were observed, as was a widespread incidence of immune complex deposits. Two animals showed chronic renal insufficiency. Lack of renal changes (minimal-changes glomerulonephritis) in two dogs was accounted for in one animal by an almost complete absence of symptoms and in the other by chronic viscerocutaneous symptoms; neither showed more than a slight immunoglobulin response.  相似文献

In 75 bitches with pyometra single urine samples were examined for gamma-glutamyl transferase (gamma-GT), protein, glucose, specific gravity, bacteria, red blood cells and white blood cells. Serum samples were examined for urea, creatinine, inorganic phosphate and gamma-GT. Biochemical findings were compared with the degree of illness (clinical signs). Twenty one bitches had no signs of renal disease. Seventeen showed only glomerular damage indicated by proteinuria without signs of proximal tubular damage. Thirty seven bitches had increased urinary gamma-GT levels, indicating proximal tubular lesions, which were associated with proteinuria in 35 and renal failure in 16 of them, and worse clinical findings. In all bitches with pyometra serum levels of gamma-GT were comparable to values in control bitches. Glomerular dysfunction seemed to precede proximal tubular lesions, so that gamma-GT-uria in bitches with pyometra was not an early but rather a late indication of a more profound degree of renal dysfunction, that is, proximal tubular renal damage developed after glomerular dysfunction and preceding renal failure.  相似文献

Glomerular disease in the dog is not only a common form of renal disease but also an important cause of chronic renal failure. The presence of immune complexes in glomerular capillary walls is a major cause of canine glomerular disease and is commonly referred to as glomerulonephritis. Leakage of plasma proteins, principally albumin, across the damaged glomerular capillary walls results in persistent proteinuria--the clinicopathological hallmark of glomerulonephritis. Recent evidence suggests that, in addition to being a marker of disease, persistent proteinuria is associated with progressive glomerular and tubulointerstitial lesions and loss of additional nephrons. Perhaps the best treatment for glomerulonephritis is the identification and correction of any underlying inflammatory, immune-mediated or neoplastic disease that results in the deposition or formation of glomerular immune complexes. In cases of idiopathic glomerulonephritis, angiotensin-converting enzyme inhibitors have been shown to decrease proteinuria and potentially slow disease progression.  相似文献
