Contributor(s): Agnes Delauche, Rosanna Marsella

Introduction

  • Disease first recognized in 1981 and appeared to have largely died out, although recently a few cases reported.
  • Cause: remains unknown.
  • Signs: regurgitation, constipation, third eyelid protrusion.
  • Diagnosis: clinical signs.
  • Treatment: symptomatic only.
  • Prognosis: guarded although some animals appear to make a full recovery.

Pathogenesis

Etiology

  • No etiological agent has been identified.
  • A number of theories have been postulated:
    • The disease was a result of treatment of flea infestations.
    • The disease was related to a substance in dried cat food.
    • The disease was related to vaccination or worming programs.
  • But none have been substantiated with any evidence.

Pathophysiology

  • Changes occur in the autonomic and sympathetic nervous system with all autonomic ganglia being affected.
  • CNS lesions with degeneration of neurons often occurs in more acute cases.
  • Neurological dysfunction   →  
    • Megaesophagus Megaesophagus  →   regurgitation and can   →   death from inhalation pneumonia.
    • Urinary dysfunction   →   distended bladder with overflow incontinence Urinary incontinence.
    • Intestinal dysfunction   →   constipation.

Timecourse

  • Acute disease usually onsets over 48 hours may be up to 7 days.

Epidemiology

  • Many epidemiology studies have been performed in an attempt to characterize a possible etiological agent.
  • There does not appear to be any discernible pattern in the distribution of cases:
    • Rural/urban environments.
    • Males and females roughly equally affected.
    • Multicat and single cat households.
    • No consistent managemental factors between cases.
