RESUMEN
Despite the disease's long history, little progress has been made toward a treatment for rabies. The prognosis for patient recovery remains dire. For any prospect of survival, patients require aggressive critical care, which physicians in rabies endemic areas may be reluctant or unable to provide given the cost, clinical expertise required, and uncertain outcome. Systematic clinical research into combination therapies is further hampered by sporadic occurrence of cases. In this Perspective, we examine the case for a One Medicine approach to accelerate development of an effective therapy for rabies through the veterinary care and investigational treatment of naturally infected dogs in appropriate circumstances. We review the pathogenesis of rabies virus in humans and dogs, including recent advances in our understanding of the molecular basis for the severe neurological dysfunction. We propose that four categories of disease process need to be managed in patients: viral propagation, neuronal degeneration, inflammation and systemic compromise. Compassionate critical care and investigational treatment of naturally infected dogs receiving supportive therapy that mimics the human clinical scenario could increase opportunities to study combination therapies that address these processes, and to identify biomarkers for prognosis and therapeutic response. We discuss the safety and ethics of this approach, and introduce the Canine Rabies Treatment Initiative, a non-profit organization with the mission to apply a One Medicine approach to the investigation of diagnostic, prognostic, and therapeutic options for rabies in naturally infected dogs, to accelerate transformation of rabies into a treatable disease for all patients.

This article looks at the existing evidence-base by which veterinary surgeons can make welfare-focused treatment choices. Narrative and structured reviews were conducted. Papers were categorised under headings based on (1) themes in the UK Animal Welfare Act (AWA 2006) - behaviour, environment, nutrition, company and health; (2) iatrogenic harm induced by treatment; (3) decision-making methods, and (4) the subjects' context (e.g. home versus laboratory). There is more information available about 'overt' problems (e.g. acute disease), than 'covert' issues (e.g. chronic pain, lack of company and obesity). Forty of 109 papers covered pain, suffering, injury and disease, compared to 69 across four other themes in the AWA. Twelve papers were identified as focusing on welfare assessment and clinical decision-making. Veterinary surgeons should consider each of the five welfare themes described in the AWA in both veterinary practice and in determining veterinary research priorities.
