Canine hyperadrenocorticism (cHAC) is a common chronic disease usually caused by a benign ACTH-producing tumour of the pituitary. The disease leads to decreased welfare of the affected animal. Effective diagnosis and subsequent treatment can result in complete normalisation of the quality of life of the pet, though it is hampered by the need for a confident and experienced attending clinician, initiating and completing the diagnostic and management process. It is further limited by the lack of accurate diagnostic tests and monitoring tools. As such, cHAC is a good example of various conditions in veterinary medicine which represent a hurdle for inexperienced clinicians to provide the expected service to the animal.

Current mainstream treatment of cHAC is focused on inhibition of adrenal cortisol production, despite the origin of the problem usually being located in the pituitary.

The project aims to identify novel methodology to optimise the diagnostic process involved in determining the presence of cHAC, which might also be translatable to the diagnosis of other diseases, as well as novel methodology to monitor and fine-tune cHAC treatment response.

SMART Objectives:

  • To develop a range of epidemiology-related skills and knowledge (available as part of the RVC Epidemiology Master’s taught programme and within the VetCompass group) (Milestone 0-12 months).
  • To develop and validate novel hyperadrenocorticism monitoring tools (0-12 months)To acquire an understanding of the application of natural language processing and participate, as a team member, in the preparation of VetCompass-derived clinical data of dogs with and without hyperadrenocorticism for further computerised interrogation (milestone: 0-12 months)
  • To analyse the differences between the two VetCompass-based populations at different time points prior to diagnosis by using novel technology platforms that specifically exploit machine learning paradigms (milestones 12-32 months)
  • Using the above gained insights into the differences, to develop a predictive diagnostic function for cHAC to enable more effective and earlier diagnosis of the condition and validate this function by application on unanalysed original VetCompass data-set (milestones 32-38 months)
  • To characterise the canine corticotroph pituitary adenoma receptor profile using a validated Multi-plex system and banked pituitary samples, to aid selection of potential pituitary inhibitors (38-42 months)
  • To participate in the running of the RVC Small Animal Endocrinology Research Clinics (0-48 months)Write up of thesis, followed by viva (milestones 38-48 months)
