… Early diagnosis and treatment can slow the progression and improve patient quality of life. Prevalence increases with age. Often pets resist being held still for the blood draw as much or more than the actual collection itself! SDMA is also not affected by some factors that can alter lab machines’ ability to read certain values like lipemia, hemolysis or icterus. Lulich JP, Osborne CA, O'Brien TD, Polzin DJ. This biomarker will show elevated levels 17 months earlier than could be seen with creatinine,” says Dr. Rubin. What is considered a normal SDMA range? Any pain involved is associated with the collection of the blood sample, since a needle is used to pierce the skin and enter a blood vessel to draw the sample. The age of onset is often related to the size of the dog. In fact about one out of ten senior dogs will have some form of kidney disease over their lifetime while it is 1 out of 3 in senior feline patients over age 15. 1 in 10 dogs. 2. will develop some form of kidney disease in their lifetime. Prevalence increases with age. Ernst, R. et al. SDMA is derived from intranuclear methylation of L-arginine by protein-arginine methyltransferases; DIAGNOSTIC APPROACH TO CKD. What is SDMA? 7. PLoS One. SDMA reference range in kittens and adult cats is almost similar. An increased SDMA indicates decreased kidney function, which can occur as a result of acute kidney injury, chronic kidney disease (CKD), or both. 6. We don’t spam! It is more specific and less affected by other body conditions with weight and muscle loss, advanced age and disease state. Blood was collected from each dog on 9 occasions, and SDMA and sCr were measured in duplicate using commercially available assays. In cases of high SDMA levels, urine analysis and other evidence of kidney disease can be checked in puppies. In dogs with kidney disease, a SDMA/creatinine ratio (μg/mg) was calculated by dividing the SDMA concentration (μg/dL) by the creatinine concentration (mg/dL). Vet Clin North Am Small Anim Pract. SDMA increases earlier than creatinine in dogs and cats as kidney function decreases. SDMA is een gevoelige indicator voor de nierfunctie, die nierfunctieverlies al vanaf 25% detecteert. SDMA was first identified in human urine in the year 1970. SDMA is considered a sensitive and early marker (more sensitive than serum creatinine) of declining GFR in dogs and cats ( … Comparative performance of IDEXX SDMA Test and the DLD SDMA ELISA for the measurement of SDMA in canine and feline serum. Approximately 26% of cats have an increased SDMA. There is a newer test available that will allow your veterinarian to monitor renal function changes much earlier than previously detected. Rytlewski, K. et al. This test can detect reduced kidney function when creatinine, BUN (Urea), and urine specific gravity are all still normal. 2016 Nov;46(6):941-60. doi: 10.1016/j.cvsm.2016.06.010. 2016. Check your inbox or spam folder to confirm your subscription. Proc ACVIM Forum, 2015. acvim.org, accessed 2015. It gives more accurate and reliable value of glomerular filtration rate (GFR) than creatinine in dogs and cats. CKD cannot be reversed or cured but treatment and management aimed at reducing the contributing factors and symptoms can slow its progression. In dogs and cats lean body mass do not appear to influence serum SDMA levels. Chronic kidney disease is a major cause of mortality in dogs and cats. Our hypothesis was that SDMA can be an earlier marker of kidney injury compared to creatinine in dogs with AP. If serum or plasma SDMA is persistently >35 µg/dl in a … Serum SDMA reference levels in puppies have been determined slightly higher than the adult. Benefits of SDMA and early diagnosis of CKD. It can be due to acute kidney injury (AKI) or chornic kidney disease (CKD) in dogs and cats. Some common causes of kidney function changes and failure can require toxins, infections, inflammation of the kidney, kidney stones (calculi), Lyme disease, neoplasia, hypercalcemia (elevated calcium), and various inherited conditions of the kidney. All the research I’ve seen on the use of SDMA in dogs and cats (including the study referenced above) has been sponsored, at least in part, by IDEXX. Traditionally, creatinine has been the blood marker that is used in the clinic to monitor renal function. In dogs, chronic kidney disease is associated with aging, and in simple terms can be considered to be the 'wearing out' of the kidney tissues. Symmetric dimethylarginine (SDMA) is considered an important biomarker of kidney dysfunction. It helps in the early detection of the kidney disease in dogs and cats. ANIMALS: Twenty apparently healthy adult dogs owned by clients or staff at a veterinary teaching hospital. Even better, 2 in 5 veterinarians in the U.S. are already including IDEXX SDMA in their routine testing, almost always at no added cost. 1,2; SDMA is betrouwbaarder dan kreatinine als biomarker voor de nierfunctie, omdat SDMA niet wordt beïnvloed door extrarenale factoren. Approximately 11% of dogs have an increased SDMA. Why should you run SDMA in all patients? Haemolysis can result into decreased SDMA serum concentrations. The IHC Group. Required fields are marked *. 1. Effects of prolonged oral supplementation with L-arginine on blood pressure and nitric oxide synthesis in preeclampsia. “SDMA is very sensitive and specific in cats. Besides early detection, SDMA also has the benefit that it is not affected by lean muscle mass. This makes it a more reliable tool for diagnosis of CKD (chronic kidney disease). This article will explain what we can learn from SDMA monitoring and how this test is run. High SDMA concentrations always do not mean renal dysfunction or the renal dysfunction was transient. Creatinine does not increase on bloodwork until 75% of renal function is lost. DOGS: If serum or plasma SDMA is persistently >18 µg/dl in a dog whose creatinine is <1.4 mg/dl (IRIS CKD stage 1 based on creatinine), this canine patient should be staged and treated as an IRIS CKD Stage 2 patient. More information can be found in the PetPlace.com library in these articles: Chronic Renal (Kidney) Failure (CRF) in Dogs and Acute Renal (Kidney) Failure (ARF) in Dogs. Why SDMA is recommended for dogs or cats? So it may have good prognostic value. SDMA is not meant to be used as a sole test- the results need to be evaluated in combination with other blood values (BUN, creatinine and others), urinalysis (especially urine specific gravity and protein level), blood pressure and potentially other tests depending on your dog’s history and clinical picture. The SDMA concentrations were higher in the hypothyroid dogs at T0 in comparison with the healthy dogs. Other tests should also be performed to ensure potential renal disease and associated complications. All the research I’ve seen on the use of SDMA in dogs and cats (including the study referenced above) has been sponsored, at least in part, by IDEXX. 1992;14(2):127153.– 2. A. et al. Kidney disease is common, with 1 in 3 cats 8 and 1 in 10 dogs 9 developing some form of kidney disease over their lifetimes. At early stages kidney disease has no visible signs and cats actually can hide disease even at advance stage so pets suffering from kidney disease may appear normal. A cohort study including fifty-four dogs with AP diagnosed using compatible clinical and laboratory parameters, abnormal SNAP … SDMA or Symmetric dimethylarginine is a biomarker and amino acid arginine that contains two methyl groups in a symmetrical orientation which is excreted by kidneys. Kidney failure, often referred to as renal failure, is a common medical condition in dogs. Methods: Retrospective study, whereby serum Cr concentrations were determined by enzymatic colorimetry and serum SDMA concentrations were determined by liquid chromatography-mass spectrometry in dogs with necropsy confirmed CKD. Epub 2016 Aug 5. When SDMA result is 15–19 µg/dL† NO The IDEXX SDMA™ Test is more reliable than creatinine. It will be included with standard blood chemistry tests. It is excreted from the bloodstream through the kidneys, if the kidneys aren’t able to filter as well as they should (like in chronic kidney disease or … This parameter has been validated in dogs and cats, and is now routinely available [ 21, 22 ]. Future insult to the kidneys can be avoided by taking precautions if diagnosed early. 2015;29(4):1036–1044. It can also be affected by decreased muscle mass, dehydration, Addison’s disease, low blood pressure or other causes of decreased cardiac function, and muscle trauma or inflammation. ‡ To see the proof and a complete list of references, visit idexx.eu/sdma. In AKI dogs, SDMA and creatinine were positively correlated (p = 0.006 r = 0.7). In pets developing chronic kidney disease (CKD) Kidney: chronic kidney disease, SDMA exceeded the reference interval earlier than serum creatinine in the majority of animals, on average 9.8 months earlier in dogs and 17 months earlier in cats. 1–3 SDMA is an exciting new test that will allow your veterinarian to monitor changes in values over time to help evaluate response to therapy/treatment, monitor progression of renal disease, decide when additional treatments should be added, and identify sudden worsening in your dog’s chronic kidney disease. Any increase in SDMA concentration above the reference interval (greater than 14 µg/dL in cats and adult dogs; greater than 16µg/dL in puppies) is considered meaningful. The IDEXX SDMA Test Algorithm will help you take the appropriate steps towards confirming disease and diagnosis when SDMA is increased. 6. SDMA Test and Early Kidney Insufficiency IDEXX Laboratories introduced a new test, the SDMA, for detecting loss of kidney function in 2015. Stable over a year at -20°C or -80°C and for two weeks at 4°C. 2018 Oct 15;13(10):e0205030. Save my name, email, and website in this browser for the next time I comment. Toy breeds attain adulthood earlier than giant breeds. Acute Renal (Kidney) Failure (ARF) in Dogs, ©Copyright 1999 - 2021. SDMA (symmetric dimethylarginine) is the amino acid, arginine, that contains two methyl groups (dimethyl) in a symmetrical orientation. 2018. Cats and dogs having borderline increase in serum SDMA and creatinine concentration should be tested again after two weeks of initial screening and every three months to assess the renal function performance and stability. The IDEXX SDMA Test: Diagnose kidney disease in dogs and cats earlier. It is slightly higher in growing puppies than adult dogs. Sources. 2015. It is very uncommon when creatinine is increased and SDMA concentration is normal. Aid in differentiating renal versus non-renal causes of elevations in BUN and creatinine Comparative performance of IDEXX SDMA Test and the DLD SDMA ELISA for the measurement of SDMA in canine and feline serum. Approximately 1 in 3 cats and 1 in 10 dogs will eventually develop kidney disease. Symmetric Dimethylarginine: Improving the Diagnosis and Staging of Chronic Kidney Disease in Small Animals. 7. Dogs with normal creatinine (AP and AKI 1 dogs) had SDMA above reference range in 38% and 33% of cases, respectively. It does not appear to be absorbed in the renal tubules of influenced by many non-renal factors. Yeramilli, M. et al. All Rights Reserved, Chronic Renal (Kidney) Failure (CRF) in Dogs, Acute Renal (Kidney) Failure (ARF) in Dogs. It has shown that in humans dietary arginine has no effect on serum SDMA concentrations so it remains unaffected with diet. Approximately 11% of dogs have an increased SDMA. METHODS: Prospective, observational study. What Does SMDA Blood Test Reveal in Dogs? Serum SDMA helps in the prediction of the impact of the hyperthyroidism treatment on kidney function test in cats and helps in identifying which cat will become azotemic after treatment. SDMA or Symmetric dimethylarginine is a biomarker and amino acid arginine that contains two methyl groups in a symmetrical orientation which is excreted by kidneys. Creatinine is not useful in diagnosing kidney health until almost 75% or kidney function is lost but SDMA does it as early as 25% both in chronic and acute kidney injury. 1. and . The first clinical study in veterinary patients was published in 2008 for SDMA levels associated with CKD (Chronic Kidney Disease) in cats. 2014. Dogs with kidney disease should be transitioned onto a kidney support diet, as studies show that it is the best way to treat and manage this disease. Dogs with kidney disease often have vomiting and signs of nausea and need to be treated with anti-sickness medication. In cases of untreated hyperthyroidism increased GFR and loss of muscle mass is common which can hide underlying CKD but SDMA is only slightly affected by hyperfiltration and not affected by lean body mass. Monitoring during rehydration therapy for patients with elevated BUN and creatinine 2005. There are many causes of renal failure and decreased kidney function over time (also known as chronic kidney disease or CKD). Kidney disease is common, with 1 in 3 cats 8 and 1 in 10 dogs 9 developing some form of kidney disease over their lifetimes.
