**Question:** Features of Acute Fulminant Hepatic failure include all of the following Except:

A. Increased G6PD activity
B. Severe jaundice
C. Hypoalbuminemia
D. Hypotension

**Core Concept:**
Acute Fulminant Hepatic Failure (AFHF) is a life-threatening condition characterized by rapid deterioration of liver function, leading to liver failure and subsequent multiorgan dysfunction. The primary cause is usually a viral hepatitis infection, such as hepatitis A, B, or E. In such cases, the liver is overwhelmed and fails to perform its crucial functions, including detoxification, bile production, and clotting factor synthesis.

**Why the Correct Answer is Right:**
The correct answer is **Increased G6PD activity**. G6PD (Glucose-6-phosphate dehydrogenase) is an enzyme that plays a crucial role in the defense against oxidative stress by catalyzing the reduction of 6-phosphogluconate to ribulose-5-phosphate in the pentose phosphate pathway.

**Why Each Wrong Option is Incorrect:**

A. **Severe jaundice** is a prominent feature of AFHF, as it occurs due to the inability of the liver to clear bilirubin from the bloodstream.
B. **Severe jaundice** is also a key feature of AFHF, as it arises from the impaired synthesis of bilirubin conjugation enzymes in the liver.
C. **Hypoalbuminemia** is a common finding in acute liver failure, as the liver synthesizes albumin and other plasma proteins. In AFHF, the liver is unable to produce sufficient amounts of albumin, leading to hypoalbuminemia.
D. **Hypotension** is a potential feature in AFHF, as the liver plays a critical role in regulating blood pressure through the synthesis of vasoactive substances like nitric oxide. However, this option is incorrect because hypotension is not exclusive to AFHF and can be present in other critical conditions as well.

**Clinical Pearl:**
A correct understanding of the key features of AFHF is crucial for diagnosing and managing this life-threatening condition promptly. The presence of severe jaundice, hypoalbuminemia, and hypotension should raise suspicion for acute liver failure. Treatment typically involves supportive care, including hemodialysis, vasopressors, and liver transplantation in severe cases.
