Special Issue Information

Dear Colleagues,

Endocrinology is a well-recognized subfield of Veterinary Internal Medicine, accounting for a relevant percentage of cases in daily practice. With the advent of new therapeutic approaches (such as new insulin therapies), monitoring strategies (for instance, the current use of continuous glucose monitoring systems for diabetic dogs and cats), genetic research and diagnostic tests (such as the use of UCCR in Addison’s disease) highlight the constant research progress of this field. This Special Issue focuses on the current trends of veterinary endocrinology, pointing to recent novelties and current challenges in well-known diseases.

Authors are invited to submit original research, case reports and review articles focusing on etiology, diagnosis, therapy, monitoring and/or prognosis of different topics of canine and feline veterinary endocrinology, including (but not limited to):

  1. Diabetes Mellitus;
  2. Hyper- and hypocortisolism;
  3. Hyper- and Hypocalcemia;
  4. Pheochromocytoma;
  5. Hypo- and Hyperthyroidism;
  6. Insulinoma;
  7. Pituitary tumors;
  8. Gastrointestinal endocrine tumors;
  9. Insulin therapies;
  10. Multiendocrine tumors;
  11. Hyper- and hypoaldosteronism.

We look forward to receiving your contributions.

Abstract
Hypercortisolism in dogs is frequently associated with systemic hypertension (SH). However, there are no studies evaluating the changes in systolic blood pressure (SBP) in dogs with adrenal-dependent hypercortisolism (ADH) during trilostane treatment or after adrenalectomy and their response to antihypertensive treatments.

Hypercortisolism in dogs is frequently associated with systemic hypertension (SH). However, there are no studies evaluating the changes in systolic blood pressure (SBP) in dogs with adrenal-dependent hypercortisolism (ADH) during trilostane treatment or after adrenalectomy and their response to antihypertensive treatments. For this reason, the objectives of this study were to evaluate the changes in SBP in dogs with ADH during the first year of trilostane treatment or after adrenalectomy, the relation with clinical control of hypercortisolism and certain laboratory parameters, and the response to antihypertensive drugs. Fourteen dogs newly diagnosed with ADH were prospectively included and evaluated at diagnosis (T0) and 1, 3, 6, and 12 months after (T1, T3, T6, and T12, respectively). Dogs were classified as hypertensive (HT; SBP ≥ 160 mmHg) and non-hypertensive. In HT dogs, benazepril was considered as the first-line drug, and, if necessary, amlodipine was prescribed. The prevalence of SH at T0 was 79%, and it was reduced to 25% at T12. Blood pressure (BP) was not associated with disease control or selected laboratory parameters at any endpoint. Only 22% of dogs with SH needed more than one drug to normalize their SBP. In all dogs surgically treated that were HT at T0, BP normalized at T3. Full article

Progesterone-related diabetes mellitus (PRDM) in dogs is known for its particular potential for diabetes remission. This narrative review aims to provide relevant detailed information on (1) the canine estrus cycle and its impact on canine diabetes mellitus (CDM) etiology and management, (2) the role of pyometra as a further cause of insulin resistance, and (3) useful individual therapeutic and preventive strategies. PRDM is recognized due to diestrus, exogenous progestogen exposure, pregnancy, and P4-production ovarian dysfunction. Pyometra represents additional inflammatory and septic negative influence on insulin sensitivity, and its diagnosis associated with CDM is therapeutically challenging. The estrus cycle’s hormone fluctuations seem to modulate peripheric insulin sensibility by influencing insulin receptor (IR) affinity and its binding capacity, as well as modulating tyrosine kinase activity. Pyometra was shown to negatively influence IR compensatory mechanisms to insulin resistance causing glucose intolerance. Spaying and pregnancy termination may cause diabetes remission in PRDM cases in a median time of 10 days (1–51). Pharmacological annulment of progesterone effects may benefit patients unable to undergo surgery; however, remission chances are virtually null. The ALIVE (Agreeing Language in Veterinary Endocrinology) project proposed new criteria for CDM diagnoses and subclinical diabetes recognition. These new concepts may increase the frequency of a PRDM diagnosis and, even more, its relevance. Spaying represents a preventive measure against pyometra and PRDM that should be individually assessed in light of its recognized benefits and harms. Full article
