Overview
Aleutian disease (AD) in mink is a fatal viral condition characterized by immune complex formation leading to multi-organ damage, particularly affecting the kidneys and blood vessels. The disease manifests through chronic infection with Aleutian disease virus (ADV), resulting in immune complex glomerulonephritis and immune complex arteritis 12.Diagnosis
Detection of ADV-specific antibodies in serum
Histopathological evidence of immune complex glomerulonephritis and arteritis
Increased eosinophil infiltration in tissues
Demonstration of extracellular immune complexes containing viral antigen in affected tissues via immunofluorescence 12Management
No specific antiviral treatments mentioned; management focuses on supportive care
Monitoring and managing secondary complications such as renal failure and vasculitis
Immunosuppressive therapy may be considered to manage immune complex-related inflammation (specific drugs and doses not detailed) 12Special Populations
Pregnancy: Transplacental infection results in milder clinical manifestations with reduced plasmacytosis and immune complex formation, suggesting a partially immunologically controlled disease expression 1
Pediatrics: Not specifically addressed in provided abstracts
Elderly: Not specifically addressed in provided abstracts
Comorbidities: Management considerations for comorbidities like renal failure secondary to glomerulonephritis are implied but not detailed 12Key Recommendations
Monitor for and manage immune complex-related complications, particularly glomerulonephritis and arteritis, in infected mink (Evidence: Moderate) 12
Consider the unique presentation in transplacentally infected offspring, noting reduced immune complex formation and milder clinical signs, when assessing disease severity (Evidence: Moderate) 1
Supportive care and close monitoring are essential due to the lack of specific antiviral treatments (Evidence: Expert opinion) 12References
