Ichthyosis-Sclerosing Cholangitis (ISC)

Ichthyosis-sclerosing cholangitis (ISC) Syndrome is a rare medical condition that affects both the skin and the liver. Below is an easy-to-understand breakdown of this condition.

• Ichthyosis: A skin disorder characterized by dry, thickened, scaly, or flaky skin.
• Sclerosing Cholangitis: A liver disease where the bile ducts inside and outside the liver become scarred, narrowed, or damaged.

Types:

While ISC is a unique condition itself, both ichthyosis and sclerosing cholangitis have various types. Here’s a summary:

1. Ichthyosis:
   • Ichthyosis Vulgaris: Common type with dry, scaly skin.
   • X-linked Ichthyosis: Caused by a genetic mutation and affects males.
   • Lamellar Ichthyosis: Thick, plate-like scales.
   • Harlequin Ichthyosis: Severe and rare; thick skin covers the body.
   • Congenital Ichthyosiform Erythroderma: Red, scaly skin.
2. Sclerosing Cholangitis:
   • Primary Sclerosing Cholangitis (PSC): The most common type, cause is unknown.
   • Secondary Sclerosing Cholangitis: Caused by a known event or condition.

While the precise classification can be detailed, in essence, there’s primary and secondary forms based on the cause.

1. Primary: Originates in the bile ducts.
2. Secondary: Caused by an external factor, such as surgery or infection.

Causes:

It’s often challenging to pinpoint an exact cause, but potential triggers include:

1. Genetic mutations
2. Infections
3. Autoimmune reactions
4. Bile duct injuries
5. Surgery-related complications
6. Medications
7. Toxins
8. Chronic alcohol use
9. Parasitic infections
10. Liver diseases
11. Cystic fibrosis
12. Previous liver transplant
13. Gallstones
14. Tumors
15. Immune system abnormalities
16. Chronic pancreatitis
17. HIV
18. Primary biliary cirrhosis
19. Inflammatory bowel disease
20. Viral hepatitis

Symptoms:

The syndrome manifests as a mix of skin and liver-related symptoms:

1. Dry, scaly skin
2. Itchy skin
3. Fatigue
4. Yellowing of the eyes and skin (jaundice)
5. Enlarged liver
6. Abdominal pain
7. Fever
8. Chills
9. Dark urine
10. Pale stool
11. Weight loss
12. Loss of appetite
13. Night sweats
14. Enlarged spleen
15. Swelling in the legs
16. Bloating
17. Chest pain
18. Difficulty breathing
19. Nausea and vomiting
20. Confusion

Diagnostic Tests:

To diagnose ISC syndrome, doctors might use:

1. Blood tests
2. Liver function tests
3. MRI scan
4. Ultrasound
5. Endoscopic retrograde cholangiopancreatography (ERCP)
6. Liver biopsy
7. Genetic testing
8. Magnetic resonance cholangiopancreatography (MRCP)
9. Physical examination
10. Urine tests
11. Skin biopsy
12. X-rays of bile ducts
13. Serum bile acids test
14. Cholangiography
15. Percutaneous transhepatic cholangiography (PTC)
16. Liver enzyme test
17. Complete blood count (CBC)
18. Antimitochondrial antibodies (AMA) test
19. Liver stiffness measurement
20. Antinuclear antibodies (ANA) test

Treatments:

Addressing both skin and liver components is vital:

1. Moisturizing creams
2. Topical steroids
3. Retinoids
4. Antibiotics (for bacterial infections)
5. Antihistamines
6. Ursodeoxycholic acid (liver disease treatment)
7. Endoscopic dilation of bile ducts
8. Liver transplant
9. Vitamin supplements
10. Phototherapy for skin
11. Bile duct surgery
12. Physical therapy for itching
13. Antipruritic medications
14. Omega-3 supplements
15. Immunosuppressive drugs
16. Balloon dilation
17. Bile acid sequestrants
18. Therapeutic endoscopy
19. Cholestyramine (for itching)
20. Antiviral medications
21. Biliary drainage
22. Stent placement
23. Percutaneous transhepatic biliary drainage
24. Lifestyle changes (healthy diet, exercise)
25. Pain relievers
26. Antioxidant supplements
27. Cool baths
28. Removal of gallstones
29. Probiotics
30. Avoiding alcohol

Drugs:

These are commonly prescribed:

1. Ursodeoxycholic acid
2. Cholestyramine
3. Rifampicin
4. Naltrexone
5. Steroids (prednisone)
6. Azathioprine
7. Methotrexate
8. Cyclosporine
9. Mycophenolate mofetil
10. Antihistamines (e.g., diphenhydramine)
11. Topical corticosteroids
12. Retinoids (e.g., acitretin)
13. Calcium channel blockers
14. Immunosuppressants (e.g., tacrolimus)
15. Antivirals (e.g., lamivudine)
16. Antibiotics (e.g., metronidazole)
17. Ursodiol
18. Obeticholic acid
19. Fenofibrate
20. Budesonide
