Mean survival time of PLE?

• A. 1 week to 1 month
• B. 6 months to 1 year
• C. 1 month to >2 years
• D. >5 years

Answer: (C)

Prognosis for protein-losing enteropathy varies widely because it’s a syndrome caused by different underlying conditions, and each one responds differently to treatment. Some animals can live only weeks if the underlying disease is severe or not easily controlled, while others respond well to dietary management, immunosuppressants when indicated, and supportive care and can survive for months to years. That broad variability means the overall mean survival time falls roughly from about one month to more than two years, which best reflects the range seen across different causes and therapies. Shorter ranges would miss many longer-lived cases, and longer ranges are less representative of the typical cross-cause average.
