Primary Biliary Cholangitis (PBC): Specialist Care
Whether you’re newly diagnosed, seeking a second opinion, or struggling to respond to first-line treatment, Dr Nadir Abbas offers the most advanced, safe care to protect your liver and help you live well.
What is Primary Biliary Cholangitis (PBC)?
Primary Biliary Cholangitis (PBC) is a long-term autoimmune liver disease. Your immune system mistakenly attacks the small bile tubes inside your liver. This causes bile to build up, leading to liver scars (cirrhosis) or liver failure if left untreated.
As a primary biliary cholangitis specialist and leading PBC specialist UK, Dr Abbas is here to stop this damage. You do not have to face this alone.
As Seen On
Stages of PBC
Early
Mild portal inflammation around the bile ducts. Often no symptoms. PBC can be detected incidentally via blood tests.
Intermediate
Inflammation spreads beyond the portal tracts. Symptoms such as fatigue or itch may begin.
Advanced
Bridging fibrosis is detectable on FibroScan or biopsy. Symptoms are more prominent.
Cirrhosis
Established cirrhosis. Requires HCC surveillance and specialist management. Preventable with early treatment.
PBC progresses gradually over many years. With effective treatment, most patients remain in the early stages and enjoy a normal life expectancy.
Regular monitoring, including FibroScan liver stiffness measurement and blood tests, allows Dr Abbas to track your stage and adjust treatment accordingly.
Symptoms of Primary Biliary Cholangitis
PBC symptoms are sometimes dismissed or misattributed for years, delaying diagnosis. If you recognise any of the following, a specialist review is advisable.
The most common PBC symptoms are:
- Persistent fatigue
- Skin itching (Pruritus)
- Abnormal liver blood tests
- Dry eyes & dry mouth
- Pain or discomfort in the upper right side of the abdomen
- Jaundice, fluid retention (ascites), portal hypertension (in advanced stages only)
Causes of Primary Biliary Cholangitis
The exact reason people get PBC is not fully known, but it is a long-term autoimmune disease. Here’s how it may develop:
Immune System Mistake
Your body’s natural defences lose the ability to tell the difference between “good” bile ducts and “bad” germs.
Genetic Links
PBC is more common in women over 40, and it may run in some families.
Triggers
In people who are already at risk, certain things in the world around them might “switch on” the immune attack.
Bile Build-up
When the tubes are damaged, bile stays in the liver and causes swelling and damage.
How Does Our PBC Specialist Diagnose It?
Dr Abbas has extensive experience evaluating both typical and atypical presentations, including AMA-negative PBC and PBC–autoimmune hepatitis overlap syndrome.
PBC Specialist Consultation
A full 30-minute check with Dr Abbas. He uses his deep PhD knowledge to map out your health.
Exact Blood Tests
Deep blood checks for specific PBC markers, like AMA.
Painless FibroScan
A quick, safe scan. It measures liver scars exactly, without using needles or biopsies.
Liver Biopsy (If Required)
Histological confirmation in complex or atypical cases; it is not always necessary.
Treatments for Primary Biliary Cholangitis
First Line Treatment
Ursodeoxycholic Acid (UDCA) is the main medicine used to treat PBC. About 6 out of 10 people get better with it. It helps your liver work better, lowers inflammation, and can keep your life expectancy normal.
Second Line Treatments
If UDCA does not help enough, other treatments include:
Obeticholic acid (OCA/Ocaliva)
Helps improve liver blood tests and liver health over time.
Elafibranor (Iqirvo)
Helps the liver and can reduce itching.
Bezafibrate
Can help with liver tests and itching. Used carefully in the UK.
Seladelpar
A newer medicine that helps with itching and liver health.
Symptom Management
- Itching: Many patients have strong itchiness. Medicines like colestyramine, rifampicin, naltrexone, sertraline, or newer IBAT inhibitors can help.
- Bone Health: PBC can affect bones, so patients often get a DEXA scan.
- Liver Checks: Patients with advanced PBC may need regular liver scans to watch for liver cancer.
Advanced Care for Non-Responding PBC
Around 40% of PBC patients have an incomplete response to first-line treatment (UDCA). For these patients, second-line therapies are now available, and timely escalation is critical.
Dr Abbas’s PhD research focused specifically on optimising outcomes for this group, and he is directly involved in initiating patients on next-generation treatments, including obeticholic acid, elafibranor, and bezafibrate.

Frequently Asked Questions
PBC is a chronic autoimmune liver condition affecting the small bile ducts. It predominantly affects women over 40, with an estimated prevalence of 1 in 1,000 women in this age group in the UK. It remains underdiagnosed — many patients are identified incidentally through routine blood tests showing elevated ALP or GGT.
PBC cannot be fully cured, but it can be effectively controlled. First-line treatment with UDCA works well in approximately 60% of patients, often normalising life expectancy. For non-responders, second-line therapies such as obeticholic acid and elafibranor can significantly slow progression and improve symptoms. Early diagnosis is key.
Diagnosis requires at least two of three criteria: a cholestatic pattern on blood tests (elevated ALP/GGT); anti-mitochondrial antibodies (AMA-M2), found in over 95% of patients; and/or liver biopsy. In AMA-negative cases, PBC-specific antinuclear antibodies (anti-sp100, anti-gp210) may be diagnostically significant. FibroScan assesses the degree of liver fibrosis non-invasively.
Consider a specialist second opinion if: your symptoms remain unexplained after initial investigation; you have not responded fully to UDCA; your diagnosis is atypical or AMA-negative; you are considering second-line therapies; or you simply want reassurance from a nationally recognised expert. Dr Abbas welcomes referrals and self-referrals from across the UK.
Cholestatic itch is one of the most distressing symptoms of PBC. Several treatments are available, including colestyramine, rifampicin, naltrexone, and sertraline. Newer agents — including IBAT inhibitors and elafibranor — have shown particular benefit. Dr Abbas takes a structured, stepwise approach to itch management, tailored to each patient’s tolerance and response.
A UDCA non-responder is someone whose liver blood tests do not normalise adequately after 12 months of UDCA treatment, as defined by validated criteria (Paris-II, Toronto, or POISE). This affects approximately 40% of PBC patients and signals an increased risk of disease progression. These patients require prompt consideration of second-line therapies — an area of specific expertise for Dr Abbas.
