Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Alcoholic and Non-alcoholic Fatty Liver Disease. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 1: A 50-year-old man with a history of alcohol abuse is found to have elevated liver enzymes, and a liver biopsy shows the microscopic features of steatosis. If the patient abstains from further drinking, this condition will most likely evolve into which of the following?
- A. Acute liver injury
- B. Chronic liver disease
- C. Cirrhosis
- D. Complete resolution (Correct Answer)
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Complete regression***
- Abstaining from alcohol can lead to **complete regression** of steatosis as the liver has a remarkable ability to heal and regenerate when inflammation is not present [1].
- With sustained abstinence, the liver enzymes can return to normal and the steatosis may resolve fully within months [1].
*Chronic hepatitis*
- Chronic hepatitis is characterized by ongoing **inflammation** and potential liver damage, which is not typically seen when a patient successfully abstains from alcohol.
- This condition usually occurs after prolonged liver injury, rather than as a direct evolution from steatosis with abstinence.
*Acute hepatitis*
- Acute hepatitis usually presents with **sudden onset of liver inflammation** often caused by viral infections or toxins, rather than alcoholic liver steatosis.
- In the context of alcohol, acute hepatitis would indicate recent and severe liver damage, which differs when the patient avoids further alcohol.
*Hyperplastic nodules*
- Hyperplastic nodules are associated with advanced liver disease, often seen in conditions like **cirrhosis**, rather than directly evolving from steatosis after alcohol cessation.
- These nodules develop as a compensatory response in chronic liver disease, which is not expected if the steatosis resolves.
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 2: Which of the following is the MOST common risk factor for hepatocellular carcinoma worldwide?
- A. HCV
- B. Alcohol
- C. HBV (Correct Answer)
- D. Aflatoxin exposure
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: HBV
- **Hepatitis B virus (HBV)** infection is the leading cause of **hepatocellular carcinoma (HCC)** globally, especially in regions with high endemicity like Southeast Asia and sub-Saharan Africa.
- Chronic HBV infection leads to persistent **inflammation and fibrosis** in the liver, increasing the risk of malignant transformation.
HCV
- **Hepatitis C virus (HCV)** is a significant risk factor for HCC, particularly in Western countries.
- While a major cause of chronic liver disease, its overall global prevalence as a cause of HCC is slightly lower than HBV.
Alcohol
- **Chronic alcohol consumption** can lead to alcoholic liver disease, cirrhosis, and subsequently increase the risk of HCC.
- However, worldwide, chronic viral hepatitis (HBV and HCV) accounts for a larger proportion of HCC cases compared to alcohol-related liver disease.
Aflatoxin exposure
- **Aflatoxins**, particularly **aflatoxin B1**, are potent liver carcinogens produced by certain fungi (e.g., *Aspergillus flavus*) that contaminate food crops.
- While significant in some regions, especially when combined with HBV infection, its global impact as a sole risk factor for HCC is less widespread compared to viral hepatitis.
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 3: Which of the following statements about alcoholic hepatitis is false?
- A. Gamma glutamyl transferase is raised
- B. Alkaline phosphatase is raised
- C. SGOT is raised > SGPT
- D. SGPT is raised > SGOT (Correct Answer)
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***SGPT is raised > SGOT***
- In **alcoholic hepatitis**, the ratio of **AST (SGOT)** to **ALT (SGPT)** is typically **2:1 or higher**, meaning SGOT is usually significantly higher than SGPT.
- This is because alcohol depletes **pyridoxal phosphate**, a cofactor for ALT, leading to relatively lower ALT levels.
*Gamma glutamyl transferase is raised*
- **Gamma-glutamyl transferase (GGT)** is frequently elevated in **alcoholic liver disease**, including alcoholic hepatitis [1].
- It serves as a sensitive marker for **biliary tract injury** and **alcohol consumption** [1].
*SGOT is raised > SGPT*
- This statement is **true** for alcoholic hepatitis, as the **AST (SGOT)** to **ALT (SGPT)** ratio is typically **2:1 or greater**.
- The disproportionately high AST is a characteristic feature reflecting the **mitochondrial damage** caused by alcohol within hepatocytes [2].
*Alkaline phosphatase is raised*
- **Alkaline phosphatase (ALP)** can be elevated in alcoholic hepatitis, although usually to a lesser extent than in obstructive jaundice [1].
- Its elevation often reflects superimposed **cholestasis** or **biliary inflammation** [1].
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 4: Which one of the following is not true about hepatocellular carcinoma?
- A. AFP is a marker
- B. Metastasis occurs late (Correct Answer)
- C. HBV is a risk factor
- D. Common in cirrhosis
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: Metastasis occurs late
- This statement is **false** because **hepatocellular carcinoma (HCC)** is known to **metastasize early**, often disseminating through the **portal vein** to the lung, bone, and brain [1].
- Early metastasis is a significant factor contributing to the **poor prognosis** of HCC even when the primary tumor is relatively small.
*AFP is a marker*
- **Alpha-fetoprotein (AFP)** is a widely used **tumor marker** for HCC, particularly in surveillance and diagnosis [1].
- While elevated AFP levels can indicate HCC, they are **not always present** and can also be elevated in other conditions such as hepatitis or cirrhosis.
*HBV is a risk factor*
- **Hepatitis B virus (HBV)** infection is a **major global risk factor** for developing HCC, especially in endemic regions.
- Chronic HBV infection leads to **chronic inflammation** and **fibrosis** in the liver, significantly increasing the risk of malignant transformation.
*Common in cirrhosis*
- HCC is overwhelmingly common in patients with **cirrhosis**, regardless of its etiology (e.g., chronic hepatitis, alcohol abuse, non-alcoholic fatty liver disease) [1].
- The **regenerative nodules** and chronic inflammation associated with cirrhosis create a fertile ground for the development of **dysplastic foci** and ultimately HCC [1].
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 5: Focal or confluent periportal necrosis, along with ballooning degeneration of hepatocytes, with or without Mallory bodies and megamitochondria, is suggestive of?
- A. Acute Hepatitis B
- B. Chronic Hepatitis B
- C. Alcoholic liver injury (Correct Answer)
- D. Primary HCC
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Alcoholic liver injury***
- Characterized by **focal or confluent periportal necrosis** and **ballooning degeneration** of hepatocytes, often in the context of alcohol abuse [1].
- Presence of **Mallory bodies** and **megamitochondria** further supports this diagnosis, linking it to alcohol consumption [1,2].
*Chronic Hepatitis B*
- Typically presents with **chronic inflammation** and **fibrosis**, not focal necrosis and ballooning degeneration [2].
- Lack of **Mallory bodies**, which are more specific to alcoholic liver damage [1,2].
*Primary HCC*
- Usually associated with **mass lesions** in the liver rather than necrosis and ballooning degeneration.
- HCC is characterized by malignant changes and **poorly differentiated cells**, not primarily necrotic hepatocytes.
*Acute Hepatitis B*
- More commonly presents with a diffuse inflammatory response and **hepatocyte necrosis**, but not specifically with ballooning degeneration and Mallory bodies [2].
- The necrosis seen is often more general rather than focal or periportal specifically.

Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 6: Which of the following is a sign of reversible injury in alcoholic liver disease?
- A. Cytoplasmic vacuole (Correct Answer)
- B. Pyknosis (nuclear shrinkage)
- C. Loss of cell membrane integrity
- D. Nuclear karyolysis (nuclear dissolution)
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Cytoplasmic vacuole***
- The presence of **cytoplasmic vacuoles** in liver cells indicates fatty change, which is a **reversible injury** in alcoholic liver disease [1][2].
- This injury allows the liver to recover if **alcohol consumption** is ceased, highlighting its reversible nature [1].
*Nuclear karyolysis*
- **Nuclear karyolysis** signifies severe cellular damage and necrosis, indicating an irreversible process [2].
- This feature involves the dissolution of the nucleus, which does not align with reversible injury.
*Loss of cell membrane*
- Loss of the **cell membrane** indicates irreversible damage, leading to cell death rather than a reversible condition [2].
- This change is associated with significant cellular impairment, contrary to the concept of recovery.
*Pyknosis*
- **Pyknosis**, the condensation of chromatin in the nucleus, suggests irreversible cellular injury and impending necrosis [2].
- It is often a precursor to cell death and is not indicative of reversible damage in liver pathology.

Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 7: Patient with Type I diabetes mellitus, with complaints of polyuria. Which of the following will occur normally in his body?
- A. Increased protein synthesis
- B. Glycogenesis in muscle
- C. Decreased cholesterol synthesis
- D. Increased conversion of fatty acid to acetyl CoA (Correct Answer)
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Increased conversion of fatty acid to acetyl CoA***
- In response to **insulin deficiency** and **hyperglycemia** in Type 1 diabetes, the body shifts from carbohydrate to fat metabolism.
- This leads to increased **lipolysis**, releasing fatty acids that are then converted to **acetyl CoA** in the liver for energy or ketone body production.
*Incorrect: Increased protein synthesis*
- **Insulin** is an **anabolic hormone** that promotes protein synthesis; its deficiency in Type 1 diabetes leads to decreased, not increased, protein synthesis.
- Instead, there's often increased **protein catabolism** to provide substrates for gluconeogenesis.
*Incorrect: Glycogenesis in muscle*
- **Insulin** is required for the uptake of glucose into muscle cells and its subsequent conversion to **glycogen (glycogenesis)**.
- In Type 1 diabetes, the lack of insulin significantly impairs muscle glucose uptake and glycogenesis.
*Incorrect: Decreased cholesterol synthesis*
- In uncontrolled Type 1 diabetes, there is actually **increased cholesterol synthesis**, not decreased.
- The increased availability of **acetyl CoA** (from enhanced fatty acid oxidation) provides substrate for cholesterol synthesis via the **HMG-CoA reductase pathway**.
- This contributes to the **dyslipidemia** commonly seen in poorly controlled diabetes, including elevated LDL cholesterol and total cholesterol levels.
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 8: All of the following are complications of cirrhosis, EXCEPT:
- A. Spontaneous bacterial peritonitis
- B. Portal hypertension
- C. Hepatic encephalopathy
- D. Hypercalcemia (Correct Answer)
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Hypercalcemia***
- While liver disease can lead to **metabolic derangements**, severe hypercalcemia is not a direct or typical complication of **cirrhosis** itself.
- Causes of hypercalcemia are usually related to **parathyroid dysfunction**, **malignancy**, or specific drug effects.
*Spontaneous bacterial peritonitis*
- This is a common and serious infection of the **ascitic fluid** that occurs in patients with cirrhosis, often without an obvious source of infection.
- It is a direct consequence of impaired immune function and bacterial translocation in **advanced liver disease**.
*Portal hypertension*
- This condition is a hallmark of cirrhosis, resulting from increased resistance to blood flow through the fibrotic liver [1].
- It leads to many other complications such as **ascites**, **esophageal varices**, and **splenomegaly** [1].
*Hepatic encephalopathy*
- This is a neuropsychiatric syndrome caused by the accumulation of toxins normally cleared by the liver, such as **ammonia**, in the systemic circulation [1].
- It is a significant complication of **cirrhosis** and often indicates advanced liver failure [1].
Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 9: A chronic alcoholic patient presents with increasing abdominal girth. A liver biopsy reveals reddish inclusions within the hepatocytes. What are these inclusions composed of?
- A. Hemosiderin
- B. Intermediate filaments (Correct Answer)
- C. Triglycerides
- D. Glycogen
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Intermediate filaments***
- In chronic alcoholic patients, reddish inclusions within hepatocytes are characteristic of **Mallory bodies** (also known as alcoholic hyaline) [1].
- Mallory bodies are aggregates of **intermediate filaments**, specifically **cytokeratin filaments**, that have been damaged.
*Hemosiderin*
- **Hemosiderin** is an iron-storage complex and appears as **golden-brown granules** within cells [1].
- While iron overload can occur in alcoholic liver disease, hemosiderin is not the primary component of the reddish inclusions described as Mallory bodies.
*Triglycerides*
- **Triglycerides** accumulate in hepatocytes in **fatty liver disease** (steatosis), which is common in alcoholics [1].
- These appear as clear lipid vacuoles rather than reddish inclusions.
*Glycogen*
- **Glycogen** is a branched polysaccharide of glucose, found in the cytoplasm, and appears as clear vacuoles or small, periodic acid-Schiff (PAS)-positive granules.
- Hepatic glycogen accumulation is not described as reddish inclusions in the context of alcoholic liver disease.

Alcoholic and Non-alcoholic Fatty Liver Disease Indian Medical PG Question 10: Which of the following is a histopathological feature of extrahepatic biliary atresia?
- A. Hepatocyte ballooning degeneration
- B. Parenchymal cholestasis
- C. Marked bile duct proliferation (Correct Answer)
- D. Fibrosis of the hepatic duct
Alcoholic and Non-alcoholic Fatty Liver Disease Explanation: ***Marked bile duct proliferation***
- Extrahepatic biliary atresia is characterized by the progressive obliteration of the **extrahepatic bile ducts**, leading to a compensatory **proliferation of intrahepatic bile ducts**. [1]
- This proliferation is a hallmark histopathological finding, reflecting the body's attempt to establish alternative drainage pathways. [1]
*Hepatocyte ballooning degeneration*
- This feature is more characteristic of acute and chronic **hepatitis**, particularly alcoholic hepatitis or non-alcoholic steatohepatitis (NASH).
- While it can occur in severe cholestasis due to toxin accumulation, it is not a primary or specific finding for biliary atresia.
*Parenchymal cholestasis*
- **Parenchymal cholestasis** refers to the accumulation of bile within the hepatocytes and bile canaliculi, which can be seen in many forms of liver disease including biliary atresia.
- However, it is a general sign of impaired bile flow within the liver and not a specific diagnostic feature distinguishing biliary atresia from other cholestatic conditions. [1]
*Fibrosis of the hepatic duct*
- While **fibrosis** does occur in biliary atresia, it typically affects the **extrahepatic bile ducts** themselves (leading to their obliteration).
- The question asks for a histopathological feature, and while fibrosis is present, **marked bile duct proliferation** within the liver parenchyma is a more specific and prominent microscopic feature used in diagnosis. [1]
