Question

A 48-year-old male with acute hepatic failure is being evaluated for liver transplantation. His urine test shows ethylene glycol positivity. Which of the following constitutes an absolute contraindication to liver transplantation?

• A. HIV infection
• B. Urine ethylene glycol positive
• C. Coronary artery disease with EF 40%
• D. Coronary artery disease with 85% stenosis

Hint:

Absolute contraindications to liver transplant include: Severe irreversible extrahepatic disease (severe cardiopulmonary disease, extensive active extrahepatic malignancy), irreversible profound neurological brain injury, active uncontrolled sepsis, and active/ongoing substance abuse without completion of a mandatory rehabilitation/observation period.

Answer 1

The Correct Option is B

Concept:
A middle-aged man is presenting with fulminant acute liver failure (ALF) and is currently undergoing urgent evaluation for an orthotopic liver transplant. Toxicology screening reveals active positivity for ethylene glycol.
The question asks to identify which of the provided clinical scenarios definitively represents an absolute, non-negotiable contraindication to proceeding with a liver transplant.
Explanation:
• The evaluation for liver transplantation is incredibly rigorous because donor organs are an exceedingly scarce and valuable medical resource. Transplant centers strict criteria to ensure maximum survival benefit.

• An absolute contraindication implies that performing the transplant would either be futile, inherently fatal to the patient, or a gross misuse of the organ due to certain graft failure.

• Ethylene glycol is a highly toxic industrial alcohol (commonly found in antifreeze). Acute, massive ingestion is often an intentional suicide attempt and rapidly causes profound systemic toxicity, including severe high-anion-gap metabolic acidosis, acute anuric kidney injury (due to oxalate crystal deposition), and catastrophic, irreversible neurological anoxic brain damage.

• In the context of liver transplant evaluation, active poisoning with a substance like ethylene glycol (Option B) is an absolute contraindication for two main reasons: First, the systemic extrahepatic organ damage (especially irreversible neurological injury) makes survival post-transplant impossible. Second, active substance abuse and acute, uncontrolled psychiatric crises (like a lethal suicide attempt) strictly preclude a patient from emergency listing until prolonged psychiatric clearance is achieved.

• Historically, HIV infection (Option A) was considered a contraindication; however, with modern highly active antiretroviral therapy (HAART), well-controlled HIV is now widely accepted as perfectly safe and is no longer an absolute contraindication for transplantation.

• Mild to moderate Coronary Artery Disease (CAD) and heart failure (Options C and D) are considered significant relative contraindications. These patients can often undergo pre-transplant cardiac optimization, such as coronary stenting or medical management, allowing them to eventually survive the hemodynamic stress of the surgery. They are not automatic absolute contraindications.
Final Answer:
Active ethylene glycol poisoning, reflecting acute toxic ingestion with massive systemic extrahepatic injury, constitutes an absolute contraindication to emergency liver transplantation.
