Nephrology 2015-2019 Flashcards
What is the clinical significance of weight in regards to cats with CKD?
Cats have lost an average of 8.9% of body weight prior to diagnosis
patients that weigh < 4.2 kg had a poorer prognosis
Weight loss is accelerated after diagnosis of CKD
What is the overal prevalence of SIRS and sepsis in cats presented to a veterinary teaching hospital?
6.2% sepsis
Mortality rate of 33% for septic cats
(javma 2017)
What role does serum magnesium play in cats with chronic kidney disease?
Inversely associated with plasma FGF23
Hypomagnesemia in 12% - independently associated w/ death
Magnesium difference not significant in multivariablel analysis
Hypomagnesemia mostly seen in cats w/ IRIS stage 4
(JVIM 2018)
How does magnesium correlated with CKD and nephrolithiasis?
Hypermagnesium in 38% and hypomagnesemia in 14.3%
Negaitve correlation with iCa, positive correlationwith phosphorus
Cats with with CKD and nephrolithiasis and magnesium derrangements had higher mortality rate (JFMS 2019)
What biochemical abnormality most strongly correlates with tubulointerstinal damage?
serum creatinine
What correlation between urolithiasis and chronic kidney disease has been noted in cats?
Prevalence of CKD is higher in cats with uroliths
Negative association of CKD w/ cystoliths
(javma 2017)
What is the overall prevalence of hemorrhagic cystitis in dogs treated with cyclophosphamide and furosemide concurrently?
3.6% in a study of 55 dogs
(javma 2016)
What is the correlation between BUN and SDMA in hemodialysis?
For every 10% increase in BUN reduction rato, there is a 6.2 ug.dL decreased in SDMA. (JVIM 2019)
What biochemical abnormalities are more likely to occur with patients that are seroreactive for borrelia C6?
Thrombocytopenic, azotemic, hyperphosphatemic, anemic, neutrophilic
Hematuria, pyuria more likely, even w/ neg culture
Histopathology often has immune complex glomerlular nephritis
What are the key clinicopathologic and histopathologic renal abnormalities noted in patients with confirmed coccidioidomycosis?
63% proteinuric - 25% clinically relevent
13% azotemic
54% of histopathology results had changes suggestive of immune complex glomerular nephritis - 71% had proteinuria
Is cPL linked to survival in hemodialysis-dependent AKI dogs.
No
No sig difference between survival or dialysis dependent or nondialysis dependent
What factors are associated with an increased risk for positive urine culture?
Low USG, female sex, CKD stage 1 (CKD 4 less, - sample size low, may not be accurate) (JVIM 2019)
Is administration of HES expected to increase AKI in cats?
When administered cummulative dose of 98.5 ml/Kg over median of 4 days - no
Effects of Hydroxyethyl starch 130/0.4 on serum creatinine concentration and development of acute kidney injury in nonazotemic cats JVIM 2017
What are considered to be prognositc factors associated with survival in dogs with CKD
BCS < 4/9 (1.6)
hyperphos (3.2)
muscle atrophy (2.3)
increased creat (1.4)
increased UPC (3.1 )
increased Calcium Phosphorus Produc (4)
increased FGF-23 (2.6)
Survival times for each IRIS CKD stage were sig different
(JVIM 2018)
What are the known long-term outcomes of cats serving as kidney donors?
Median hospitalization 3.5 days
84% had no long term effects
7% developed renal insufficiency or died or developed urinary tract disease (javma 2016)
How does HES impact AKI grade and serum creatinine concentration in dogs?
AKI grade not significantly different at evaluated short and long term points
Number of days was associated with increased AKI grade
cummulative dose did not affect
What percentage of CKD patient with a positive urine culture are symptomatic?
30% of dogs had positive culture 8% symptomatic
E. coli most common
More dilute urine a risk factor
(JVIM 2019)
What are known risk factors for the development of candida urinary tract infection in dogs?
ABX admin w/in 30 days, immunosuppression
DM and hospitalization NOT associated (JVIM 2019)
What is the surivival rate of uroabdomen?
79% - more complications = increased mortality
creatining not associated
What is the clinical significance of cystatin C in cats with hyperthyroidism and CKD?
Cannot predict CKD and does not change after treatment
Serum cystatin C concentrations in cats with hyperthyroidism and CKD JVIM 2016
What breeds are overrepresented as serorreactive for Borrelia C6?
Retrievers and mixes
Which of the following most accurately correlates with GFR: creatinine, SDMA, cystatin C
creatinine > SMA > cystatin c
Comparison of the diagnostic value of symmetric dimethylarginine, cystatin C, and creatinine for detection of decreased glomerular filtration rate in dogs JVIM 2019
What urinary marker may increased before UPC in familial amyloidosis in Abyssinian cats?
urinary Serum Amyloid A
What correlations can be drawn between periodontal disease and CKD in cats?
Periodontal disease had increased risk of associated CKD - highest for IRIS 3 and 4
Increased risk with age
Purebred more likely - Siamese, Himalayan, Abyssinian
General anesthesia w/ 1 yr before study and cystitis at any ponit increased risk
DM or hepatic lipidosis associated with decreased risk (osmotic diuresis in DM and increased BW with hepatic lipidosis)
