Primary biliary cholangitis symptoms and effective treatment

Primary Biliary Cholangitis (PBC) is a chronic autoimmune disease that affects the small bile ducts within the liver. Over time, it leads to the gradual destruction of these ducts, causing bile to build up and damage liver tissue. This condition is most common in women over the age of 40 and may initially present with no noticeable symptoms. As it progresses, it can cause persistent fatigue, itchy skin, and yellowing of the eyes and skin (jaundice).In this article on Dalili Medical, we reveal the main causes of PBC, the early warning signs you shouldn't ignore, the latest diagnostic methods, and the most effective treatments currently available. We also share practical tips to help you live better with the disease and improve your daily quality of life.

1. How long can someone live with PSC?

Primary Sclerosing Cholangitis (PSC) progresses slowly, and many patients live for many years. Symptoms often develop gradually over 10 to 15 years. With careful medical follow-up, the progression of the disease can be slowed, and quality of life can be improved.

2. Is PSC a contagious disease?

❌ No, PSC is not contagious. It doesn’t spread through food, blood, or physical contact, as it results from an autoimmune dysfunction, not an infection.

3. Does alcohol play a role in the development of PSC?

❌ There is no proven direct link between alcohol consumption and the development of PSC. However, it is always best to avoid alcohol to protect the liver and reduce complications.

4. Can PSC be completely cured?

❌ There is no definitive cure for PSC at present. However, symptoms can be managed, and liver damage can be slowed with medications, regular follow-up, and nutritional support.

✅ Regular follow-up with a hepatologist helps determine the right timing.

⚠️ Foods and Drinks to Avoid with PSC

A proper diet is essential to reduce inflammation and support liver health. Avoid:

Raw or undercooked shellfish
- May carry harmful bacteria or viruses (e.g., Vibrio, hepatitis A) dangerous to the liver
- Cook seafood thoroughly before eating
Saturated and trans fats
- Found in butter, margarine, fried and fast foods
- Worsen liver fat buildup and inflammation
Simple carbohydrates
- White bread, sugar, pastries, sweets
- Can spike blood sugar and worsen insulin resistance
Excessive salt
- Increases fluid retention—especially risky for patients with ascites
Alcohol (all forms)
- Completely forbidden—it accelerates liver damage

✅ Dietary Recommendation:
Follow a liver-friendly diet that is:

Low in fat and salt
Rich in fruits and vegetables
Includes lean protein (well-cooked chicken and fish)
Hydration is key—drink plenty of water

❓ What Are the Causes of Primary Sclerosing Cholangitis (PSC)?

While the exact cause of PSC remains unknown, it is believed to result from a complex interplay among immune dysfunction, genetics, and environmental triggers. Key potential contributors include:

Autoimmune Dysfunction (Most Likely Cause)
The immune system mistakenly attacks the bile ducts, leading to chronic inflammation and progressive fibrosis, which obstructs bile flow and damages the liver.
Association with Inflammatory Bowel Disease (IBD)
About 70–80% of PSC patients also have ulcerative colitis or Crohn’s disease, indicating a strong link between intestinal immune dysregulation and PSC.
Genetic Predisposition
A family history of PSC or autoimmune diseases increases the risk. Certain genes like HLA‑B8 and DR3 are implicated, suggesting a hereditary component.
Environmental Factors
Hypothesized triggers include:
- Bacterial or viral infections
- Disruption of gut microbiota
- Exposure to toxins or chemicals
  However, none of these have been conclusively proven.
Gender and Hormonal Influence
PSC predominantly affects men, unlike PBC which is more common in women, suggesting possible hormonal or sex-related influences.

✅ Types of PSC | Primary Sclerosing Cholangitis Types

PSC manifests in several distinct forms, each with unique clinical and diagnostic features:

Classic PSC
- Most common type
- Affects both intrahepatic and extrahepatic bile ducts
- Often associated with ulcerative colitis
- Diagnosed via MRCP (Magnetic Resonance Cholangiopancreatography) or ERCP (Endoscopic Retrograde Cholangiopancreatography)
- Characterized by multiple strictures and irregular duct dilations (beading pattern)
Small‑Duct PSC
- Involves only the small bile ducts inside the liver
- Imaging often appears normal; diagnosis requires liver biopsy
- Typically has milder course, lower risk of bile duct cancer, and better long-term prognosis
PSC–AIH Overlap Syndrome
- Features combined PSC and autoimmune hepatitis (AIH)
- Patients often test positive for ANA and ASMA
- Respond well to immunosuppressive therapy (e.g., corticosteroids)
- Requires a dual treatment approach
IBD‐Associated PSC
- Most common subtype among PSC patients with inflammatory bowel disease
- PSC may precede, coincide with, or follow IBD diagnosis
- Colonic inflammation often less active, but PSC can silently progress

✅ Stages of PSC | Progression Overview

PSC typically progresses over several stages, from mild inflammation to liver failure:

Stage 1: Bile Duct Inflammation
- Early inflammatory changes in duct walls
- Usually asymptomatic
- Mild elevation in ALP and GGT found on blood tests
Stage 2: Biliary Strictures
- Partial fibrosis and duct narrowing
- Bile stasis develops
- Symptoms like itching, fatigue, and more pronounced enzyme elevations
Stage 3: Bridging Fibrosis
- Extensive liver fibrosis
- Signs of liver dysfunction appear: hepatosplenomegaly, ascites, and coagulation changes
Stage 4: Cirrhosis
- Liver architecture deteriorates into fibrotic tissue
- Complications include portal hypertension, esophageal varices with bleeding, severe ascites, and increased risk of cholangiocarcinoma
End‑Stage Liver Disease
- Complete loss of liver function
- Liver transplantation becomes essential

✅ Symptoms of PSC

Early (often subtle):

Chronic unexplained fatigue
Persistent itching (pruritus)
Mild liver enzyme abnormalities (often incidentally discovered)

Advanced:

Jaundice (yellowing of skin and eyes)
Upper right abdominal pain
Dark urine, pale or clay‑colored stools
Unexplained weight loss, appetite loss
Recurrent fevers (especially during cholangitis)

Severe/Complicated:

Ascites (abdominal fluid buildup)
Enlarged liver and spleen
Gastrointestinal bleeding from varices
Hepatic encephalopathy (confusion, memory issues, impaired cognition)

Associated IBD symptoms:

Chronic diarrhea
Blood in stools
Abdominal cramps

✅ Complications of PSC

As PSC advances, the potential complications include:

Cirrhosis from chronic inflammation and fibrosis
Liver failure, often requiring transplantation
Cholangiocarcinoma (bile duct cancer) in approximately 10–15% of patients
Hepatocellular carcinoma—less common, but risk increases with cirrhosis
Recurrent cholangitis causing fever, pain, and exhaustion
Ascites due to portal hypertension or liver failure
Esophageal varices and gastrointestinal bleeding
Hepatic encephalopathy due to toxin accumulation in the brain
Fat‑soluble vitamin malabsorption (A, D, E, K) leading to bone fragility, bleeding tendencies, and immune dysfunction
Coexisting autoimmune diseases, frequently ulcerative colitis, Crohn’s disease, or rheumatologic disorders

✅ Diagnosis of PSC

Diagnosis involves combining clinical assessment, lab tests, imaging, and sometimes biopsy:

History & Physical Exam: Evaluate symptoms like itching, fatigue, jaundice, history of IBD or autoimmune conditions, and signs like hepatosplenomegaly
Blood Tests:
- Liver function (ALP, GGT) elevated
- Aminotransferases (ALT, AST) elevated to a lesser degree
- Bilirubin elevated in later stages
- Autoimmune markers: ANA, p-ANCA, SMA, and IgG4 level (to exclude IgG4‐related cholangitis)
Imaging:
- MRCP is the most accurate for detecting bile duct changes
- ERCP reserved for complex or therapeutic purposes due to higher risks
- Ultrasound may show liver enlargement or bile duct obstruction
Liver Biopsy: Not always necessary—used when imaging is inconclusive (e.g., small‐duct PSC), or to assess fibrosis
Diagnostic Criteria:
- Persistent elevation of ALP
- Characteristic bile duct changes on MRCP or ERCP
- Exclusion of other cholangiopathies (such as PBC, AIH, or IgG4‐associated disease)

Treatment of Recurrent Infections

Antibiotics, tailored to the specific bacteria involved
Preventive strategies to reduce the risk of recurrence, if necessary

Treatment of Osteoporosis

Vitamin D and calcium supplements
Bone-strengthening medications such as bisphosphonates in certain cases

3. Liver Transplantation

Liver transplant is the only definitive treatment in the following situations:

Severe deterioration of liver function
Recurrent episodes of acute cholangitis
Development of cholangiocarcinoma (bile duct cancer)

Note: Outcomes after transplantation are generally excellent, though PSC may recur in the transplanted liver in 10–20% of cases.

4. Regular Follow-up

Monthly or periodic blood tests to monitor liver function
MRCP or ERCP imaging regularly, depending on the case
Routine colonoscopies if the patient also has ulcerative colitis

General Recommendations

There is no specific diet for PSC, but a balanced diet rich in proteins and vitamins is recommended
Alcohol should be completely avoided
Vaccination is essential against:
- Hepatitis A and B
- Influenza
- Pneumococcus

✅ PSC Prevention & Self-Care Guidance

Although Primary Sclerosing Cholangitis (PSC) is a rare disease with no clearly defined cause, making complete prevention impossible, the following strategies may help:

Reduce the risk of complications
Preserve liver function
Improve quality of life

✅ 1. Monitor Associated Bowel Diseases

Over 70% of PSC patients also suffer from ulcerative colitis or other inflammatory bowel diseases (IBD)

Ongoing follow-up with a gastroenterologist is crucial
Colonoscopy every 1–2 years is recommended for early detection of colon cancer

✅ 2. Preventive Vaccinations

To protect the liver from viral infections:

Vaccine	Purpose
Hepatitis A	To prevent viral hepatitis A
Hepatitis B	To protect an already compromised liver
Influenza & Pneumococcus	To prevent common infections that may strain the liver

✅ 3. Avoid Alcohol and Hepatotoxic Substances

Alcohol accelerates liver damage and increases fibrosis risk
Avoid herbs or medications that may harm the liver without medical supervision

✅ 4. Healthy Diet

Eat balanced meals rich in fruits and vegetables
Limit animal fats and processed foods
Ensure proper absorption of fat-soluble vitamins (A, D, E, K), especially in case of deficiencies

✅ 5. Physical Activity

Engage in regular moderate exercise to boost immunity and circulation
Avoid a sedentary lifestyle that can worsen fatigue and muscle weakness

✅ 6. Periodic Liver Function Monitoring

Track liver enzymes (ALP, GGT), bilirubin, albumin, and INR
Perform MRCP scans as directed by your doctor

✅ 7. Genetic Counseling (if family history exists)

In rare cases, PSC may follow a genetic pattern. Genetic counseling may help with:

Assessing the risk of inheritance
Taking early preventive measures

❌ Final Note:

There is no guaranteed method to prevent PSC. However, early detection and effective management are key to reducing symptoms and slowing disease progression.
