Small-Duct Sclerosing Cholangitis

Primary Sclerosing Cholangitis (PSC) is a complex liver disease that can affect people of all ages. In this simplified guide, we will break down the types, causes, symptoms, diagnostic tests, treatments, and drugs related to PSC in plain English. Our goal is to make this information easily understandable, so everyone can grasp the basics of this condition.

Types of Primary Sclerosing Cholangitis:

  1. Classical PSC: The most common form of PSC, affecting the bile ducts inside and outside the liver.
  2. Small-Duct PSC: A less common type where only the small bile ducts inside the liver are affected.

Possible Causes of Primary Sclerosing Cholangitis:

  1. Autoimmune Factors: PSC may be linked to the body’s immune system mistakenly attacking the bile ducts.
  2. Genetics: Family history of PSC can increase the risk.
  3. Inflammation: Ongoing inflammation in the liver can lead to PSC.
  4. Infections: Some infections might trigger PSC in susceptible individuals.
  5. Environmental Factors: Certain toxins or pollutants may play a role.
  6. Gut Health: Changes in gut bacteria could contribute to PSC.
  7. Inflammatory Bowel Disease (IBD): PSC is often seen in people with IBD, like Crohn’s disease or ulcerative colitis.
  8. Viral Infections: Viruses such as Epstein-Barr may be linked to PSC.
  9. Medications: Some drugs might be associated with PSC.
  10. Hormones: Hormonal imbalances could potentially influence PSC development.
  11. Dietary Factors: Diet may affect the risk of developing PSC.
  12. Obesity: Being overweight or obese may increase the risk.
  13. Smoking: Smoking is a possible risk factor.
  14. Alcohol: Excessive alcohol consumption may contribute to PSC.
  15. Geography: PSC is more common in certain regions.
  16. Age: PSC can occur at any age, but it’s often diagnosed in young adults.
  17. Gender: Men are more commonly affected than women.
  18. Liver Flukes: Parasitic infections can trigger PSC in some cases.
  19. Metabolic Conditions: Conditions like diabetes may increase PSC risk.
  20. Unknown Factors: In some cases, the exact cause remains unclear.

 Common Symptoms of Primary Sclerosing Cholangitis:

  1. Fatigue: Feeling very tired is common in PSC.
  2. Itching (Pruritus): Skin itching, often worse at night, can be bothersome.
  3. Jaundice: Yellowing of the skin and eyes due to bile buildup.
  4. Abdominal Pain: Discomfort or pain in the upper right abdomen.
  5. Dark Urine: Urine may become dark in color.
  6. Pale Stools: Stools may appear pale or clay-colored.
  7. Weight Loss: Unintended weight loss can occur.
  8. Loss of Appetite: A reduced desire to eat.
  9. Fever: Low-grade fever may be present.
  10. Nausea: Feeling queasy or sick to the stomach.
  11. Vomiting: Some people with PSC may vomit.
  12. Enlarged Liver or Spleen: The liver or spleen might become bigger.
  13. Joint Pain: Joint discomfort or inflammation.
  14. Osteoporosis: Weakened bones due to poor nutrient absorption.
  15. Dry Eyes or Mouth: Known as sicca syndrome, it can cause dryness.
  16. Gallstones: An increased risk of gallstones exists.
  17. Skin Rash: Some skin conditions are associated with PSC.
  18. Depression: Emotional well-being can be affected.
  19. Cognitive Issues: Rarely, cognitive problems may occur.
  20. Blood in Stool: This could be a sign of gastrointestinal bleeding.

Diagnostic Tests for Primary Sclerosing Cholangitis:

  1. Blood Tests: Liver function tests and specific markers.
  2. Imaging: MRCP (Magnetic Resonance Cholangiopancreatography) or ERCP (Endoscopic Retrograde Cholangiopancreatography) to visualize bile ducts.
  3. Liver Biopsy: A small sample of liver tissue is examined.
  4. Ultrasound: To assess liver and bile ducts.
  5. CT Scan: Provides detailed images of the liver and surrounding organs.
  6. Liver Function Testing: Measures how well the liver is working.
  7. Cholangiography: Dye is injected to outline bile ducts.
  8. Endoscopic Ultrasound: Combines ultrasound with an endoscope.
  9. FibroScan: Measures liver stiffness, an indicator of liver damage.
  10. Colonoscopy: To check for associated IBD.
  11. Magnetic Resonance Elastography (MRE): Evaluates liver stiffness.
  12. Liver Enzyme Tests: Assess enzyme levels in the blood.
  13. Serum Autoantibodies: Checks for autoimmune markers.
  14. Inflammatory Markers: Measure inflammation in the body.
  15. Bile Duct Brushing: Collects cells for examination.
  16. Lipid Profile: Evaluates blood fat levels.
  17. 24-Hour Urine Collection: Checks for liver-related abnormalities.
  18. Antinuclear Antibodies (ANA) Test: Screens for autoimmune disorders.
  19. Percutaneous Transhepatic Cholangiography (PTC): Visualizes bile ducts via a catheter.
  20. Liver MRI with Contrast: Enhanced MRI for detailed liver assessment.
