Subject groups/Research projects
- Comparative Pathobiology:
Canine and feline liver and pancreas disease
Penny Watson’s research focuses on liver and pancreas disease in dogs and cats, particularly chronic disease and fibrosis. There is a strong focus on comparative pathology and identifying the relevance to humans as well as small animals. Her work on canine chronic pancreatitis, in collaboration with Prof Michael Herrtage and pathologists in Cambridge (Tim Scase, Aude Roulois and Fernando Constantino-Casas) and Glasgow and funded by BSAVA Petsavers, has defined the prevalence of lesions at post mortem and breed-related differences in pancreatic pathology which suggest differences in aetiology between breeds. Concurrent clinical studies funded by the Pet Plan Charitable Trust identified the same breed relationships and showed the importance of chronic pancreatitis in causing clinical disease in dogs. Initial work in English Cocker spaniels suggest a disease similar to autoimmune chronic pancreatitis in humans. Ongoing studies in English Cocker spaniels, in collaboration with Fernando Constantino-Casas at Cambridge and Professor Michael Day at Bristol are investigating whether their disease is similar to human IgG4+ related disease. Genetic studies are also ongoing in the breed with Julien Bazelle (clinical resident - residency completed 2013), David Sargan and Jesus Aguirre-Hernandez.
Cavalier King Charles spaniels (CKCS) have also been identified in this research as having an increased risk of chronic pancreatitis and ongoing work in this breed is investigating potential mechanisms of multi-organ fibrosis and the role of platelet-derived mediators including serotonin. The initial part of this work is funded by BSAVA Petsavers and is being undertaken with Fernando Constantino-Casas and James Warland (clinical resident) and in collaboration with veterinary colleagues Professor Michael Day from the University of Bristol, Claire Rusbridge from the University of Surrey and Brendan Corcoran from the University of Edinburgh.
Chronic hepatitis in dogs is another key research focus. Dr Nick Bexfield’s PhD funded by the Wellcome Trust and co-supervised by Penny Watson with Prof Jon Heeney and Laurence Tiley investigated the potential role of novel viruses in the disease and also described breed-related hepatitis in the English Springer Spaniel (ESS). Novel methods of viral discovery have so far failed to find a convincing aetiological agent. Nick also demonstrated that the recently described canine hepacivirus does not appear to be associated with chronic hepatitis in dogs and has shown an association between the dog leukocyte antigen and chronic hepatitis in the ESS. Ongoing work continues to investigate the genetics of the disease in the ESS and to try to identify the cause with the help and support of the breed health co-ordinators.
Biliary tract disease in dogs and cats is also an active research interest. An Emesis Council award has enabled Ben Harris (clinical resident – residency completed in 2012) to undertake a study of the prevalence and importance of biliary tract infections in dogs, including fluorescence in situ hybridization of dogs' livers in collaboration with Tristan Cogan at Bristol and other colleagues from the veterinary schools at Dublin, Bristol, Liverpool and Glasgow and at Dick White Referrals.
Penny also has ongoing interests in a number of smaller student and resident clinical research projects, particularly in gastroenterology and clinical nutrition. Congenital portosystemic shunts have been a long term interest, particularly medical management, and she has published a number of book chapters and reviews on pancreatitis and liver disease in dogs and cats.
