What Is Idexx SDMA In Dogs

What range does a typical SDMA use?

A substantial rise in SDMA concentration is one that is bigger than the reference interval (more than 14 g/dL in cats and adult dogs, and greater than 16 g/dL in pups).

A higher-than-normal SDMA concentration indicates a compromised glomerular filtration rate (GFR). When SDMA readings are slightly elevated (15–19 g/dL), take action by running a thorough urinalysis. If there is chronic evidence of renal illness, use the algorithm to determine what to do next.

What levels in dogs signify renal failure?

SLE, often known as the “great imitator,” can present as a disease of the joints, kidney, skin, mucous membranes, or nails, making it challenging to diagnose. Numerous organ locations, including the kidneys, might be impacted by the animal’s unfavourable and aberrant immune reaction to its own body tissues and proteins.

The aberrant immunological molecules are caught in the glomeruli and blood arteries as the kidneys filter the blood, causing the kidney to leak protein. Glomerulonephritis is the next ailment, and the injured glomeruli can lead to various kinds of impaired kidney function.

The accumulation of a protein called amyloid can develop in any tissue of the body, even though it has not been demonstrated to be a result of an autoimmune illness. The most common organ affected is the kidney, and because kidney tissue cannot heal itself, renal amyloidosis can be particularly dangerous because the protein accumulation disrupts normal function.

Diagnosis of Kidney Failure

Increased thirst, or polydipsia, is one of the first symptoms an animal exhibits when renal failure starts to impact it. Increased levels of toxins and other metabolic waste products set off brain receptors that the blood is excessively concentrated, and as a result of a series of chemical events, the animal may feel dehydrated. To counteract this sensation, your dog drinks more water. This feeling of dehydration is exacerbated by actual water loss through the kidneys above normal levels because the kidneys are ineffective in retaining water in the body.

Increased thirst and water consumption (polydipsia) also lead to increased urine production. The increased urine production, known as polyuria, defies logic if the animal has kidney failure.

When the veterinarian suggests that the patient may be experiencing early renal failure, many pet owners are perplexed. “How can that be, it’s urinating a lot more than it typically does,” they frequently reply. The truth is that although more pee is being produced and excreted, it is becoming more and more diluted, and the toxins and waste products are not being carried out of the body with it.

Your veterinarian will use both a urine and blood sample to make the diagnosis of renal failure. If one is checked without the other, the diagnosis may not be accurate.

The kidneys are unable to concentrate urine in the majority of cases of renal failure. As a result, the Urine Specific Gravity measurement (SpG), which measures the urine’s concentration in relation to distilled water (SpG = 1.00), will show a dilute reading that is actually rather close to pure water.

Since the kidney’s tubules are responsible for conserving water while allowing unwanted metabolites and toxins to stay in the urine, when the tubules are damaged water conservation is less effective, which causes more water to flow through the tubules unreabsorbed and wash away in the now diluted urine.

The SpG in the majority of renal failure cases ranges from 1.008 to 1.012. A typical dog’s urine SpG will range from 1.020 to 1.040.

The urine specific gravity increases in a water deprivation test if the animal is denied access to water for 18 hours (i.e., the urine becomes more concentrated).

The urine in many cases of renal failure also contains protein or sugar, but in the majority of normal animals the urine contains little to no protein and no glucose. The animal is in a negative protein/energy balance due to the loss of, or failure to reabsorb, protein or sugar molecules after an initial passage into the tubular fluid. Muscle wasting and weight loss are symptoms of this condition. Additionally, because these animals don’t eat much, the additional stress of protein and energy loss in the urine tends to make maintaining a normal body weight all but impossible.

Patients who suffer from chronic renal failure may have blood and bacteria in their urine samples. Urine samples may frequently contain infectious pathogens, red and white blood cells, epithelial cells from the lining of the kidney and bladder structures, crystals, and protein plugs known as casts that develop from injured tubules. On the other hand, some patients’ urine is so watery and they are so thirsty that a urine sample may not reveal any cells or other debris at all, only a low specific gravity and extremely watery pee.

What are the early indications of canine renal failure?

The disease known as renal failure, sometimes known as kidney failure, can be brought on by a variety of illnesses that affect the kidneys and other organs. The kidneys of a healthy dog function to get rid of pollutants, control hydration, keep an appropriate electrolyte balance, and release hormones to make red blood cells. The kidneys are no longer functioning as effectively as they should in dogs that have renal failure.

Types of Kidney Failure in Dogs

Acute and chronic renal failure are the two main types encountered in canines.

Chronic Renal Failure: The progressive loss of kidney function over weeks, months, or years is the hallmark of chronic kidney failure. Degeneration of the kidneys brought on by ageing is often the cause of chronic renal failure in dogs. Although most dogs with chronic renal failure are unable to fully recover, this condition is frequently successfully treated, allowing them to live happily for several months or years.
Acute Renal Failure – Over a period of hours or days, kidney function abruptly declines, indicating acute kidney failure. The most common causes of this kind of renal failure are infections or toxin exposure. Acute renal failure is frequently curable if detected and treated in a timely manner.

Causes of Kidney Failure in Dogs

Renal failure may result from any disorder that affects the kidneys, including:

Congenital diseases include underlying illnesses, inherited problems, and birth defects such cysts and kidney absence in one or both kidneys.
Bacterial illnesses – Leptospirosis is one bacterial infection that can affect your dog’s body, inflaming the kidneys and killing off the renal cells.
Toxicosis: When toxins or poisons are accidentally consumed by your dog, it might result in kidney damage.
Dental disease – If bacteria accumulates on your dog’s teeth and gums, it may result in an advanced form of the condition. The kidneys, heart, and liver of your dog could suffer damage if that bacteria were to enter its bloodstream and internal organs.
Cells degrade and die as your dog ages, a condition known as geriatric degeneration. This occurs throughout the body, especially in the kidneys where it may cause renal failure and illness.

Symptoms of Kidney Failure in Dogs

You may observe one or more of the following symptoms if your dog has kidney failure:

Loss of weight
nausea and diarrhoea
White gums
instability or stumbling
chemical odour in the air
significant appetite loss
Significant changes in water use
Urine volume changes, either rising or falling
oral sores
urethral blood
Lethargy
Seizures

Get your dog to the vet as soon as possible if he is exhibiting symptoms of kidney failure. It is crucial to receive an accurate diagnosis and start therapy as soon as feasible in order to produce positive treatment outcomes.

Treatment for Kidney Failure in Dogs

Treatment will depend on your dog’s overall health and the underlying cause of their kidney issues, as it does with many other disorders.

If your pet has severe renal failure, immediate and intensive care will be needed, frequently in the intensive care unit at your veterinary clinic. However, if detected early, milder forms of acute renal failure may be treated at home with fluids, antibiotics, and medicines. In some circumstances, treating canine acute renal failure with dialysis may be advised.

The main goals of chronic renal failure treatment will be to delay the disease’s progression and enhance your dog’s quality of life. Treatment options for chronic kidney disease symptoms include nausea, fluid imbalances, and changes in blood pressure may include drugs as well as dietary adjustments for your dog.

Many dogs who receive treatment for chronic renal failure go on to live long, happy lives. Specific nutrients, nutritional supplements, or a therapeutic diet may be advised to assist manage your dog’s illness and enhance your dog’s quality of life.

Preventing Kidney Failure in Dogs

When dogs eat chemicals, tainted foods, or stuff they shouldn’t eat, like grapes or chocolate, they frequently develop acute renal failure. Pay close attention to the items in your home that could poison your dog to help prevent the development of acute renal failure in dogs. Keep poisonous items like antifreeze, prescription drugs for humans, and potentially hazardous foods well away from your dog.

Chronic kidney failure typically develops with age and is genetically predisposed, making prevention much more challenging. To counter this, routine wellness examinations twice a year at your primary care veterinarian’s clinic will assist to improve the likelihood of identifying symptoms quickly so that treatment may start before the issue gets worse.

What does a dog’s SDMA test look for?

Dog health issues might be challenging to diagnose. Veterinarians can easily diagnose chronic kidney disease (CKD) in its advanced stages, but it can be quite difficult to spot in its early stages. This is because to the possibility that symptoms like increased drinking and urination, a loss of appetite, and less energy could be absent, minor, or related to another health issue. Veterinarians required an animal-specific diagnostic tool to enhance early kidney function detection. The symmetric dimethylarginine (SDMA) test was discovered to accomplish this.

In a blood test, what is idexx SDMA?

A novel renal biomarker called symmetric dimethylarginine (SDMA) should be used in conjunction with creatinine, BUN, and a urinalysis to better accurately and quickly diagnose kidney illness. Additionally, SDMA has been included in the staging recommendations for chronic renal disease from the International Renal Interest Society (IRIS) (CKD).

What makes dogs’ SDMA levels so high?

A higher-than-normal SDMA* concentration indicates a compromised glomerular filtration rate (GFR). An increase in SDMA concentration can result from both primary renal disease and secondary kidney insults, such as concurrent illness. Investigate increased SDMA levels using this algorithm to identify whether an injury is acute, active, or chronic. Use the method to control and monitor an enhanced SDMA as well as to do additional research and management.

What canine meals aid in kidney repair?

You might be considering what to feed your dog especially and whether to make their food yourself or buy a brand that is manufactured commercially. Making your dog’s food in your kitchen gives you more control because you know exactly what it contains (aside from what he gets in the yard when you are not looking). There are several commercial diets, nevertheless, that might also be effective. The food must satisfy your dog’s nutritional needs whether you want to feed them a homemade diet or buy them kibble. Feed dogs with kidney problems a diet rich in high-quality protein, low in phosphorus and sodium, and supplemented with omega-3 fatty acids, such as a combination of good quality meat, vegetables like bell peppers, and either fish, flax, sardines, or anchovies. A good variety of proteins is preferred, ideally raw. Avoid kibble, commonly referred to as dry food, as it might dehydrate an animal. Making your own dog food can take a lot of time and effort, but if you do, make sure to follow a recipe so you don’t forget any essential items. In order to create a comprehensive and balanced diet, additional nutrients must be supplied in addition to the main food components. And it can be challenging to provide those nutrients effectively and in the proper amounts at home.

Remember that you can and should modify this diet based on what is available, especially over the course of a week, as one of its key tenets. In the veterinary world, there is a lot of discussion and speculation about what constitutes a balanced diet. Over the course of the week, the main suggestion is:

12–15% meaty bone
10% to 30% organ meat
30 to 50 percent of the meat is muscle.
5% fish

Keep added fats to a minimum, avoid starch, and most importantly, give your dog variety. Fish is always an excellent choice, but just once or twice a week is plenty.

If you can discover food that can satisfy your dog’s dietary needs, commercial diets can be suitable for dogs with kidney illness. Unfortunately, the majority of pet store meals contain too much phosphorus to have the intended effect. Your dog will require less phosphorus as their kidney illness worsens. For your dog’s renal diet, high moisture content food is essential. The gold standard for eating is a raw diet that includes high-quality protein. Commercial raw dog foods are available for purchase.

You could see the following qualities listed on commercial dog food:

Organic: These foods aren’t exposed to ionising radiation, pesticides, fertilisers, preserving agents, or genetically engineered organisms. Antibiotics and growth hormones are not administered to the animal if it is meat. This distinction is crucial for renal diets since it indicates that the food is toxin-free, which reduces the stress on your pet’s existing organ function.
Low levels of phosphorus are recommended because they raise survival chances and are likely to decrease the course of renal disease. Phosphorous to Calcium Ratio: Phosphorous should be low. The ratio of calcium to phosphorus ought to be higher.
Fresh Food: In reality, what is meant by “fresh food” is how bioavailable it is to your dog. In other words, food that is simple to digest will deliver the most nourishment.
Raw food diets, also referred to as the Biologically Appropriate Raw Food (BARF) diet (bones and raw food), include uncooked meats as well as various fruits, vegetables, cereals, and vitamins.
No Kibble: As mentioned above, feeding kibble to dogs that have kidney illness is not a good idea. It causes a dehydrated dog to become even more dehydrated.
Canned: When feeding your dog with kidney problems, canned food is unquestionably a better option than kibble. Although it has greater moisture, salt or other preservatives would be added to keep it fresh in the can. This is not the best for your dog. Food that is canned must go through heat processes, which depletes it of several vitamins.
Reduced Sodium: Low sodium diets are recommended since high sodium diets aggravate renal damage and raise blood pressure.
Increased Omega-3 Fatty Acids: In certain kidney regions, Omega-3 Fatty Acids aid in reducing inflammation and hypertension. They also aid in enhancing renal performance.
Increased B-Vitamins: You may make up for the B-vitamins your dog loses through pee by giving them more of them in their meals. Water-soluble B vitamins are lost more quickly in sick kidneys.
Additional antioxidants: Antioxidants protect against cellular deterioration and strengthen the immune system.
Decreasing Phosphorus: As was already said, reduced phosphorus can help dogs with kidney disease have better renal function and live longer.
Dietary Fat/Calories: A dog’s kidneys may become overworked if they consume too much fat in their food. However, when your dog has kidney disease, they can tolerate larger levels of fat in their food, so it might be a smart approach to boost their calorie intake.
Reduce Nitrogenous By-Products and Waste: High levels of nitrogen in the blood are frequently caused by urea, creatinine, and other bodily wastes. The disorder known as uremia is brought on by incorrect waste product excretion. The poor filtration of the kidneys might cause nitrogen to accumulate to extremely high levels. In other words, when the kidney is in late-stage failure, nitrogen levels rise and can be detected in the blood. In order to lessen the nitrogenous byproducts, proteins should be lowered at this point.
Potassium Citrate: When blood bicarbonate levels in all phases of renal illness are low, this supplement increases them. Your dog’s blood’s bicarbonate level drops as a result of their blood becoming more acidic due to reduced kidney function.

However, high-quality commercial dog food for a dog with kidney problems should have the following:

Animal products
Fruits and vegetables whole
Fresh
80 to 85% of the total weight is water
Simple to Digest Proteins

The Association of American Feed Control Officials (AAFCO), which controls the sale and distribution of food and medications for animals, has rules that your dog’s food must adhere to.
