stress hyperglycemia in cats

Struggling and lactate concentrations were predictive of hyperglycemia. Ankara Üniversitesi Veteriner Fakültesi Dergisi, 2019. Download Download PDF. Link KR, Rand JS. The results of the retrospective investigation show in cats transient hyperglycemia occurs more often (3.2%) than permanent hyperglycemia (0.57%). Stress hyperglycemia and insulin resistance are evolutionarily preserved responses that allow the host to survive during periods of severe stress. Fructosamine concentrations in hyperglycemic cats. These cats are scared but rather than become aggressive they remain crouched in the back of the cage, often have dilated pupils, and usually are flac- cid when handled. Diabetes (Diabetes Mellitus) in Cats - PetCoach pathogenesis and progression of feline DM. This is often a temporary increase in blood sugar, and while it warrants further observation, it may not be cause to diagnose chronic hyperglycemia or diabetes mellitus. Full PDF Package Download Full PDF Package. Cats in general are prone to high blood sugar, typically during times of stress, where glucose levels may reach 300-400mg. What triggers diabetes in cats? In general, cats are susceptible to high blood sugar level, commonly during periods of stress, where the glucose might reach about 300 to 400 milligrams. Dogs and cats in the early stages of nonclinical DM appear healthy, have a stable weight, and are usually identified as a result of Hypoglycemia most commonly occurs in cats with diabetes. 5 Though an oversimplified explanation, this . A particular issue in feline patients. Normal blood glucose in a cat ranges from approximately 80-150 mg/dL, but when cats are stressed (by going for a car ride, seeing the cat carrier, etc. Gluconeogenesis stimulated by lactate release is the likely mechanism for hyperglycemia in healthy cats in this model of acute stress. There is scarce information about the effects of stress-related hyperglycemia and its effect on insulin secretion and HOMA-IR. The cells metabolize the glucose to provide energy for your cat's everyday functioning. This needs further attention in future studies. It can make their blood sugar shoot up significantly above normal. Diabetes can be caused by an increased production of glucose and an insufficiency of insulin to assimilate the glucose. Feline hyperglycemia is the technical term for high blood glucose in cats. stress hyperglycemia in cats, corticosteroid administration, the pres-ence of concurrent insulin-resistant disease (hyperadrenocorticism, obesity), or as part of the early stage of developing DM. Home Community Stress hyperglycemia. Symptoms and Types However, cats present us with a unique challenge because their glucose levels can become markedly increased simply due to stress. In conclusion, stress hyperglycemia occurs in cats when their blood glucose level shoots up mainly because of stress. However, hyperglycemia can also be caused by stress, so further tests (i.e., levels of fructosamine) are needed. Home Community Stress hyperglycemia. In some circumstances, despite the pres- Results of routine hematological and urine laboratory tests ence of food, the cat did not show abnormal behavior (e.g., were within the reference range, except for the presence of when the owners were having breakfast in their bedroom or hyperglycemia (268 mg/dL, reference interval [RI]: 86-116 when . No variation in stress induced hyperglycemia among diabetic and non-diabetic patients or stress induced processes of To 200 or even higher. in this study, the investigators characterized the changes in blood glucose concentrations in healthy cats exposed to a short stressor and determined the associations between glucose concentrations, behavioral indicators of stress, and blood variables implicated in stress hyperglycemia (plasma glucose, lactate, insulin, glucagon, cortisol, … promote the stress induced hyperglycemia. Many cats are susceptible to "stress-induced" hyperglycemia in which the serum glucose concentrations may approach 300-400 mg/dl. Feline Stress Induces Examination Abnormalities. Effects of Allium tuncelianum on oxidative stress and hyperglycemia in rats with diabetes mellitus induced by streptozotocin. Stress hyperglycemia []. Research output: Contribution to journal › Article › peer-review history, and laboratory results. Diabetes mellitus (DM) is a common endocrinopathy in cats, with reported prevalence rates ranging from 0.4% to 1.2%. . 2, 03.2002, p. 121-122. (Personal experience of one canine caregiver indicates a reading can be 50+ points higher, depending on whether or not the pet liked the doctor or tech doing . Editorial: Stress Hyperglycemia and Diabetes Mellitus in Cats Editorial: Stress Hyperglycemia and Diabetes Mellitus in Cats Nelson, Richard 2002-03-01 00:00:00 results may lead to the erroneous perception that the diabetic cat is poorly controlled. [Stress hyperglycemia in cats] It may be difficult to differentiate the possible causes of hyperglycemia in the cat. Useful in confirming diagnosis in cats. An examination of an overly stressed cat may show elevations in heart and respiratory rates. Stress hyperglycemia describes the transient increase in blood glucose in sick cats or in cats displaying signs of fear. The symptoms of hyperglycemia will include: A cat who has been previously diagnosed with diabetes . Cats are easily stressed by blood draws, transportation to the veterinarian, separation from their caretaker, and other actions. 82 For glucose to reach a cell with reduced blood flow (ischemia, sepsis), it must diffuse down a concentration gradient from the bloodstream, across the interstitial space, and into the cell. Distinguishes hyperglycemic, cats without diabetes, from cats with diabetes and chronic hyperglycemia. / Nelson, Richard. 1-4 The vast majority of cats with experimentally induced diabetes developed an initial period of insulin resistance, with the associated persistent hyperglycemia directly reducing functional pancreatic beta cell mass. 18 Catecholamine & Cortisol Excess Conditions associated with elevated concentra - tions of catecholamines and/or cortisol produce hyperglycemia by inducing insulin resistance. A diabetic cat should receive treatment as soon as possible, as a constant excess of non-metabolized glucose can cause a lot of damage in the cat's body. Cats in basic are susceptible to high blood sugar, normally during times of stress, where glucose levels may reach 300-400mg. This means their blood sugar can spike up to 200 or even 300 mg/dL in severe cases! Gluconeogenesis stimulated by lactate release is the likely mechanism for hyperglycemia in healthy cats in this model of acute stress and careful handling techniques that minimize struggling associated with blood collection may reduce the incidence of stress hyperglyCEmia in cats. Cats are easily stressed by blood draws, transportation to the veterinarian, separation from their caretaker, and other actions. Any upset to the routine or misapplication of insulin can lead to the cat going into a hypoglycemic state. Some normal cats can have a condition called stress-induced hyperglycemia (high blood sugar). Handheld glucometers use a small drop of blood and an algorithm for species-specific adjustment related to the red blood cells and distribution of glucose to determine blood glucose levels. Blood glucose concentrations in cats with stress hyperglycemia were between 8.1 and 60.4 mmol/l (Median 10.3), in cats with diabetes mellitus between 8.5 and 70.0 (Median 27.7). Stress hyperglycemia poses a challenge for veteri- narians using blood glucose concentrations for diagnosis and management of diabetes mellitus in cats. Rand JS, Kinnaird E, Baglioni A, Blackshaw J, Priest J. J Vet Intern Med, (2):123-132 2002 MED: 11899027 This is because a diabetic cat requires a diligent, daily routine of timed feedings, insulin injections and moderate exercise. Acute mobilization of glucose. Changes in blood glucose concentration are associated with relatively rapid changes in circulating . Academia.edu is a place to share and follow research. 5 Cats in general are prone to high blood sugar, typically during times of stress, where glucose levels may reach 300-400mg. Abstract. Diabetes mellitus. Under stress (such as being in a veterinary office), these cats can rapidly develop high blood glucose levels (300-400 mg/dL; normal is 55-160 mg/dL). One of the most common is the AlphaTRAK 2 glucose monitor with canine- and feline-specific settings, but other glucometers can also be used. When cats get nervous (which is common during a vet visit), their blood sugar can be temporarily but significantly elevated just due to stress — even if the cat is otherwise perfectly healthy and not diabetic. It's in proportion to the blood glucose concentration over the lifespan of the glycated protein being measured. Aside from high stress scenarios, damaging drug interactions (such as with heartworm medication), and consumption of nutritional services including high glucose, the following are prospective causes to hyperglycemia: Low glucose intake within the body resulting in high blood glucose levels. Browse By Title: "Hyperglycemia Following Head Trauma" to "Hyperglycemia Decreases Acute Neuronal Ischemic Changes After Middle Cerebral Artery Occlusion in Cats" This is the same high glucose level that can be observed in some diabetic cats. PZI is still a good choice for long-term treatment of diabetes in cats, and is typically given subcutaneously twice daily. The current study suggested that hyperglycemia could trigger ER stress-ATF6-CHOP axis, inhibit β-catenin activation, accelerate in fl ammation, and deteriorate liver IRI, thus providing the . . Because cats, being cats, have a unique reaction to acute stress. While most cats are generally healthy, some develop medical conditions similar to humans, including hyperglycemia, or high blood sugar. In these uncertain cases a lab test known as a fructosamine concentration can be helpful. Hypoglycemia is defined as a blood glucose (sugar) concentration of less than 70 milligrams per deciliter (mg/dl) of blood. 2002;16(2):123-132. Stress hyperglycemia occurs as a result of the increased hepatic output of glucose rather than impaired tissue glucose extraction . In states of chronic stress, stimulation of hepatic gluconeogenesis by excess glucocorticoids can cause high concentrations of glucose in sick cattle (around 300-500 mg/dL but as high as 1000 mg/dL) (e.g. In addition, renal glycosuria may be found in animals with renal tubular disease and occasionally with stress-induced hyperglycemia. Stress has been found to cause temporary hyperglycemia in cats (Rand et al., 2002), and therefore, blood glucose concentrations may be overestimated due to stress-induced changes in blood glucose. 16, No. J Vet Intern Med. Because cats, being cats, have a unique reaction to acute stress. While the circulating catecholamine inhibits insulin secretion from the beta cells, it tends to paradoxically boost the processes of gluconeogenesis and glycogenolysis in the liver. Insulin therapy is invariably adjusted, often by increasing the insulin dosage, and another blood glucose curve recommended 1 to 2 weeks later. Cats, however, show more variability in the presence of a stress leukogram and elevated ALP. Measurement of serum fructosamine can assist in differentiating between stress-induced hyperglycemia and diabetes mellitus. Some cats may have an increased level of glucose due to stress or excitement. The aims of this study were 1) to establish a reference range for fructosamine in cats using a commercial fructosamine kit; 2) to demonstrate that the fructosamine concentration is not increased by transient hyperglycemia of 90 min duration, simulating hyperglycemia of acute stress; and 3) to determine what percentage of blood samples submitted to a commercial laboratory from 95 sick . Insulin is a hormone produced by the pancreas that facilitates the passage of glucose into an animal's cells. In cats, stress can induce transient hyperglycemia that makes it harder to diagnose and manage diabetes. Symptoms depend on how quickly the blood glucose concentration decreases, but rarely occur until it falls below 50 mg/dl. Rapid heart rates can sometimes cause abnormal heart sounds that cannot be differentiated from sounds associated with real heart disease without an echocardiogram. Stress hyperglycemia is often associated with patient struggling and glucose values can be as high as 1088 mg/dl (60 mmol/l) and remain raised for up to 90-120 mins, with or without glucosuria. Symptoms of hyperglycemia in cats Tissue damage Wounds fail to heal on time Severe depression Nerves in the legs are affected Enlargement of liver Bloodshot eyes Cataract Dehydration Continuous hunger Obesity Weight loss Polyuria or increased urination Polydipsia or increased thirst In: Journal of veterinary internal medicine / American College of Veterinary Internal Medicine, Vol. In cats, stress hyperglycaemia is a major factor confusing diagnosis and monitoring of diabetes, and struggling can increase blood glucose by as much as 180 mg/dL (10 mmol/L). Careful handling techniques that minimize struggling associated with blood collection may reduce the incidence of stress hyperglycemia in cats. In cases of stress-induced hyperglycemia, the fructosamine concentrations are normal. These data suggest that moderate hyperglycemia (blood glucose of 140 to 220 mg/dL) maximizes cellular glucose uptake while avoiding hyperosmolarity. The most common cause of elevated blood glucose levels, also called hyperglycemia, in felines is a malfunction within a cat's endocrine system. This is called "stress hyperglycemia." So, other tests are used in addition to BG to help diagnose feline diabetes. In the early stages of disease, cats may present with vague signs such as "seems a little off" or "less interactive lately." Stress hyperglycemia can further complicate or delay diagnosis. The most common test for this in humans is . . In our study, hyperglycemia was induced using STZ (40 mg/kg b.w), STZ has the ability to preferentially affects pancreatic β-cells by causing toxicity. This is often a temporary increase in blood sugar, and while it warrants further observation, it may not be cause to diagnose chronic hyperglycemia or diabetes mellitus. This "stress hyperglycemia" can . The stress of a veterinary office visit or the mild restraint associated with obtaining a blood sample may significantly increase your cat's serum glucose value. Animals with overt diabet … This Paper. Prevalence of stress hyperglycemia in cats: a retrospective study of 646 cases P Frezoulis, N Soubasis, T Petanides, M Saridomichelakis, T Theodorou, D Kasabalis, A Papa, P Bouza-Rapti, T Chochlios, Theodora Tsouloufi, M Kritsepi-Konstantinou, T Rallis Dogs frequently show increased levels of alkaline phosphatase (ALP) and alanine aminotransferase. 3 Risks for similar complications are poorly defined in dogs and cats, but a few studies have suggested links between hyperglycemia and outcome in nondiabetic dogs with cardiac disease 4 and sepsis. Stress hyperglycemia (the "white coat" syndrome some pets display with visits to the veterinarian) can approach diabetic levels, and can in some instances be high enough to cause glycosuria--glucose in the urine. Rand JS, Kinnaird E, Baglioni A, Blackshaw J, Priest J. BG may exceed the renal threshold (approximately 260 mg/dl [14-16 mmol/L] and result in glucosuria) Diabetes mellitus is a common endocrine problem in dogs and cats caused by inadequate insulin production or peripheral insulin resistance. As discussed earlier, cats are prone to stress hyperglycemia, which means their blood sugar goes up when they are . The frequency and degree of stress-hyperglycemia and its relation to different types of primary diseases was proven. Cats can develop a short-term elevation in blood glucose as a response to stress, known as stress hyperglycemia. stress hyperglycemia can also be present in diabetic cats that are easily removed from the cage and do not resist the blood sampling procedure. This is typically a temporary increase in blood sugar, and while it necessitates more observation, it might not be cause to identify chronic hyperglycemia or diabetes mellitus. It can make their blood sugar shoot up significantly above normal. Stress hyperglycemia results in a new glucose balance, allowing a higher blood 'glucose diffusion gradient' that maximizes cellular glucose uptake in the face of maldistributed microvascular flow [23]. The oxidative stress is often seen related to inflammation in many dysfunctions, especially, DM (Muriach et al., 2014). This problem can cause a normal blood sugar level of 82 to 122 mg/dl to go up to or over 500 in cats. Ali Bilgili. In cats, stress-induced hyperglycemia is a frequent problem, and multiple blood and urine samples may be required to confirm the diagnosis. o NOTE: Stress can cause hyperglycemia, . clinical sign of advanced feline diabetes is a plantigrade stance. Diagnosing Feline Diabetes. Fructosamine (frook-TOH-sah-meen) is a sugar-albumin complex that forms in chronic hyperglycemic conditions. 41. However, stress alone can result higher blood-sugar levels (up to 300 to 400) in cats without diabetes, attributed to a surge of released adrenaline. A glucose concentration of greater than or equal to 140 mg/dl (7.77 mmol/l) in the fasted animal was defined as hyperglycemia. Diagnosing feline diabetes can be challenging due to their propensity to develop stress-induced hyperglycemia. Serum fructosamine is formed by glycosylation of serum protein such as albumin and the concentration of fructosamine in serum is directly related to blood glucose concentration. Helps evaluate long-term control and owner compliance with insulin treatment. Furthermore, both the admission as well as the mean glucose level during the hospital stay is strongly associated with patient outcomes. Moreover, this is often a provisional increase in the blood sugar, and though it warrants more observation, it might not cause to analyze chronic hyperglycemia, or even diabetes mellitus. Blood glucose concentrations in cats with diabetes mellitus were significantly higher than in cats with stress hyperglycemia. One product, PZIVet™ , a preparation of 90% beef insulin and 10% pork insulin, was removed from the market last year, but PZI is still available from compounding pharmacies. Acute stress hyperglycemia in cats is associated with struggling and increased concentrations of lactate and norepinephrine. This process results in a waste product called ketones. Many cats are susceptible to "stress-induced" hyperglycemia. This test gives a rough average of a cat's blood glucose concentration over the last two weeks, so would not be affected by stress hyperglycemia. Diabetes mellitus is a condition that occurs in cats which is characterized by high blood sugar. Up to 30% of patients can have blood glucose levels greater than 200mg/dl after trauma and higher than normal values in the majority of these patients can be seen [ 7 ]. Alternatively, the cat's person can perform the glucose curves at home with the use of a glucometer, an in-home glucose-measuring device. A1C testing is not affected by it, giving the veterinarian a high degree of confidence in their diagnosis and management protocol for their feline patients. Typical findings include hyperglycemia, glucosuria, and stress leukogram, as well as increased cholesterol and triglycerides. Hyperglycemia in hospitalized humans is associated with a higher risk for certain complications and may affect mortality. The levels of glucose in the blood of a feline with diabetes may be as high as 600 mg per dL. These are relatively easy to use and most people can become quite comfortable using them. Causes of Type 1 and Type 2 cat diabetes The biggest factor under our control is a cat's weight. Blood glucose concentrations in cats with stress hyperglycemia were between 8.1 and 60.4 mmol/l (Median 10.3), in cats with diabetes mellitus between 8.5 and 70.0 (Median 27.7). Stress hyperglycemia is common in critically ill patients and appears to be a marker of disease severity. The following investigation was on transient hyperglycemia in 320 cats. Symptoms and Types Cats presenting persistent classic clinical signs of diabetes, such as polydipsia (PD), polyuria (PU), and weight loss despite good appetite should be further monitored for corroborative laboratory test results showing hyperglycemia and glycosuria. Plasma immune-reactive insulin (IRI) was estimated by RIA. 18,19 Prior to diagnosing a patient with diabetes mellitus, clinicians should take stress responses into account. Clinicians, researchers and policy makers have assumed this association to be causal with the widespread adoption of protocols and programs for tight in . Not influenced by stress hyperglycemia in cats. The cause of hyperglycemia in these cats is unknown however IR or undetected stress-related hyperglycemia is possible. . Stress hyperglycemia and diabetes mellitus in cats. cats.2-4,8,15 -19 < Increasing age Cats over 7 years old are at greatest risk.2,4,18 < Breed Burmese cats have been reported to have a higher risk in studies from Australia, New Zealand and Europe.2,20,21 < Physical inactivity indoor and inactive cats are at increased risk.2,3,20,22 < Gender Male cats and neutered cats are at higher risk.2 . Stress (Excitement) Hyperglycemia. This PowerPage reviews the key principles of recognizing and managing diabetic dogs and cats. Acute pancreatitis. Because stress-induced hyperglycemia can result in blood glucose concentrations of 300 mg/dL to 400 mg/dL, it can confound the interpretation of blood glucose results. A urine sample may help in confirming the diagnosis. When a sick cat becomes hyperglycemic, the body can't use glucose for fuel and starts breaking down fats for energy. Although fast- ing blood glucose greater than 200 mg/dL is consistently At the time of stress, cats glucose level can touch 300 to 400 mg. Good tool for assessing for the presence of diabetic remission. proximal duodenal obstruction; see below). Stress hyperglycemia can lead to false diagnosis especially in cats. To 200 or even higher. Stress-induced hyperglycemia may cause serum glucose elevations of up to 300-400mg/dl and result in falsely elevated blood glucose level tests. Catecholamine excess (pheochromocytoma in dogs, stress hyperglycemia in cats) acts at the levels of liver, muscle and kidney to counter the action of insulin but usually is not a significant contributor to IR because the catecholamine release is episodic. Client Concerns and History • Weight loss (or owner's perception that a diet is finallyworking) • Drinking more . To diagnose feline diabetes, veterinarians use the following tests: Fasting blood-sugar level : Test results that show a blood-sugar level over 200 indicate the possibility of diabetes. A fructosamine test is a blood test that is used in animals to measure the average level of glucose control over the past few weeks. Below is an overview of Hypoglycemia in Cats followed by detailed information about the causes . Treatment. ), they get a temporary increase in their blood sugar (called a "stress hyperglycemia"). Acute stress hyperglycemia in cats is associated with struggling and increased concentrations of lactate and norepinephrine. In cats, stress hyperglycaemia is a major factor confusing diagnosis and monitoring of diabetes, and struggling can increase blood glucose by as much as 180 mg/dL (10 mmol/L). Stress-induced hyperglycemia may cause serum glucose elevations of up to 300-400mg/dl and result in falsely elevated blood glucose level tests. Method of measurement Blood glucose (BG) values of 144-360 mg/dL (8-20 mmol/L) may be falsely elevated due to stress.
