Diagnosis, Treatment and Monitoring
of Hyperadrenocorticism

CAUTION: Federal (USA) law restricts this drug to use by or on the order of a licensed veterinarian. As with all drugs, side effects may occur. In field studies and post- approval experience, the most common side effects reported were: anorexia, lethargy/depression, vomiting, diarrhea, elevated liver enzymes, elevated potassium with or without elevated sodium, elevated BUN, decreased Na/K ratio, hypoadrenocorticism, weakness, elevated creatinine, shaking, and renal insufficiency. In some cases, death has been reported as an outcome of these adverse events. VETORYL Capsules are not for use in dogs with primary hepatic or renal disease, or in pregnant dogs. Refer to the prescribing information for complete details or visit www.Dechra-US.com.





Confirming the diagnosis of hyperadrenocorticism (HAC)
No test for HAC has 100% diagnostic accuracy. The diagnostic value of all endocrine tests will be significantly enhanced by performing them only when clinical signs consistent with HAC are present in the patient. Three endocrine diagnostic tests are available, al with particular advantages and disadvantages: Sensitivity & Specificity Urinary Cortisol to • Highest sensitivity of all three tests • To avoid false-positive results, urine samples should Creatinine Ratio (UCCR) makes it a great screening test be collected at home at least two days after a visit to a veterinary clinic • Highest confidence in a negative test • Collect first urine sample from patient in the morning • Lacks specificity • Specificity and sensitivity can be increased when urine from 2-3 days is pooled and collectively tested • False positives are relatively common and when the test is performed on dogs showing symptoms consistent with HAC • High sensitivity • Long test (8 hours) • High confidence in a negative test result • In some cases may differentiate between PDH and • Moderate specificity • False positives can occur • Considered the screening test of choice unless latrogenic HAC is suspected • Highest specificity of all three tests • Relatively short test (1 hour) • Highest confidence in a positive test • Test of choice if there is a history of exogenous steroid • Lacks sensitivity• False negatives are relatively common For detailed information on performing and interpreting these tests, please contact Dechra Veterinary Technical Services at (866) 933-2472 or your reference laboratory consult line.
Differentiating between types
It is necessary to differentiate between Pituitary Dependent Hyperadrenocorticism (PDH) and Adrenal Dependent Hyperadrenocorticism (ADH) to provide a more accurate prognosis and enable the full range of possible treatments to be discussed with the dog's owner.
Discriminatory tests available to differentiate between PDH and ADH include the low- and high-dose dexamethasone suppression tests, ultrasonography, and advanced imaging such as MRI and CT and measurement of endogenous ACTH.

These two dogs had clinical signs consistent with hypoadrenocorticism (lethargy, anorexia, collapse) and post-ACTH cortisol levels ≤ 0.3 µg/dL. Both dogs responded to trilostane discontinuation and supportive care, and one dog required continued treatment for hypoadrenocorticism (glucocorticoids and mineralocorticoids) after the acute presentation. Additional adverse reactions were observed in 93 dogs. The most common of these included diarrhea (31 dogs), lethargy (30 dogs), inappetence/anorexia (27 dogs), vomiting (28 dogs), musculoskeletal signs (lameness, worsening of degenerative joint disease) (25 dogs), urinary tract infection (UTI)/hematuria (17 dogs), shaking/shivering (10 dogs), otitis externa (8 dogs), respiratory signs (coughing, congestion) (7 dogs), and skin/coat abnormality (seborrhea, pruritus) (8 dogs). Five dogs died or were euthanized during the study (one dog secondary to adrenal necrosis, discussed above, two dogs due to progression of pre-existing congestive heart failure, one dog due to progressive central nervous system signs, and one dog due to Adrenocortical suppressant for oral use in dogs only. cognitive decline leading to inappropriate elimination). In addition to the two dogs with adrenal necrosis/rupture and the two dogs with hypoadrenocorticism, an additional four dogs were removed from the study as a result of possible trilostane-related adverse reactions, including collapse, lethargy, inappetence, and trembling.

post exposure prophylaxis (pep)

Post Exposure Prophylaxis (PEP) Occupational exposure Occupational exposure refers to exposure to potential blood-borne infections (HIV, HBV and HCV) that may occur in healthcare settings during performance of job duties. Post exposure prophylaxis (PEP) refers to comprehensive medical management to minimise the risk of infection among Health Care Personnel (HCP) following potential exposure to blood-borne pathogens (HIV, HBV, HCV). This includes counselling, risk assessment, relevant laboratory investigations based on informed consent of the source and exposed person, first aid and depending on the risk assessment, the provision of short term (four weeks) of antiretroviral drugs, with follow up and support. Who is at risk? All Health Care Personnel, including emergency care providers, laboratory personnel, autopsy personnel, hospital employees, interns and medical students, nursing staff and students, physicians, surgeons, dentists, labour and delivery room personnel, laboratory technicians, health facility sanitary staff and clinical waste handlers and health care professionals at all levels. Also at risk are public safety workers, including law enforcement personnel, prison staff, fire-fighters, workers in needle exchange programme and workers in HIV programmes. What is the risk? Health Care Personnel are at risk of blood-borne infection transmission through exposure of a percutaneous injury (e.g. needle-stick or cut with a sharp instrument), contact with the mucous membranes of the eye or mouth of an infected person, contact with non-intact skin (particularly when the exposed skin is chapped, abraded, or afflicted with dermatitis or contact with blood or other potentially infectious body fluids. potentially infectious body fluids Any direct contact (i.e., contact without barrier protection) with concentrated virus in a research laboratory or production facility requires clinical evaluation. Transmission of HIV infection from human bites is rarely reported. The average risk of acquiring HIV infection from different types of occupational exposure is low compared to risk of infection with HBV or HCV. In terms of occupational exposure the important routes are needle stick exposure (0.3% risk for HIV, 9–30% for HBV and 1–10% for HCV) and mucous membrane exposure (0.09% for HIV).e What is infectious and what is not? Exposure to blood, semen, vaginal secretions, cerebrospinal fluid, synovial, pleural, peritoneal, pericardial fluid, amniotic fluid and other body fluids contaminated with visible blood can lead to infection. Exposure to tears, sweat, saliva, urine and faeces is non-infectious unless these secretions contain visible blood. Step 1: First aid in management of exposure For skin — if the skin is broken after a needle-stick or sharp instrument:
