1st line – 

ursodeoxycholic acid

All patients should be treated with pharmacotherapy to modify disease progression. First-line treatment suitable for use in all patients is ursodeoxycholic acid.​[14][15]

Up to 40% of patients fail to respond adequately to ursodeoxycholic acid in terms of biochemical improvement and are at significantly increased risk of dying of PBC or needing liver transplantation.[47][48]​​ Non-response is more common in patients presenting below the age of 50.[47]

Ursodeoxycholic acid can cause nausea or weight gain but has no significant side effects.[63] Changing the pattern of dosing (building up the dose slowly or changing to multiple daytime dose from single night-time dose and vice versa) can improve tolerance. Treatment must be spaced away from colestyramine (by at least 4 hours) to avoid binding and reduction in the efficacy of both drugs.

Primary options

ursodeoxycholic acid: 12-16 mg/kg/day orally given in 3 divided doses

Additional treatment recommended for SOME patients in selected patient group

Elafibranor or seladelpar may be used in combination with ursodeoxycholic acid for patients with an inadequate response to ursodeoxycholic acid.

Elafibranor is a peroxisome proliferator-activated receptor (PPAR)-alpha and -delta agonist. Elafibranor is approved by the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) for use in combination with ursodeoxycholic acid in patients with inadequate response to ursodeoxycholic acid. It is also recommended for this indication by the National Institute of Health and Care Excellence in the UK.[49] In one phase 3 placebo-controlled trial of patients with PBC with an inadequate response to ursodeoxycholic acid, elafibranor significantly improved biochemical response (alkaline phosphatase level <1.67 times the upper limit of normal, with a reduction of ≥15% from baseline, and total bilirubin at or below the upper limit of normal) and reduced serum alkaline phosphatase compared with placebo at 52 weeks.[50] The most common adverse effects associated with elafibranor included abdominal pain, diarrhoea, nausea, and vomiting.[50] Elevated creatine phosphokinase levels and muscle injury were also more common in patients who received elafibranor, including one patient who developed serious rhabdomyolysis.[50]

Seladelpar is a PPAR-delta agonist. Seladelpar is approved by the FDA and EMA for use in combination with ursodeoxycholic acid in patients with an inadequate response to ursodeoxycholic acid. In one phase 3 trial, seladelpar significantly improved biochemical response, alkaline phosphatase normalisation, and reduced moderate-to-severe pruritus at 12 months compared with placebo.[51] Adverse effects more common with seladelpar treatment included headache, abdominal pain, nausea, and abdominal distention.[51]

Elafibranor and seladelpar are not recommended for patients who have or develop decompensated cirrhosis.

In some cases, non-response reflects the presence of a more inflammatory process with some features typical of autoimmune hepatitis. Treatment for patients with suspected PBC/autoimmune hepatitis overlap is directed at the predominant histological pattern of injury.[15] See Autoimmune hepatitis.

Primary options

elafibranor: 80 mg orally once daily

OR

seladelpar: 10 mg orally once daily

antipruritic treatment

Treatment recommended for ALL patients in selected patient group

The severity of pruritus in PBC is not related to the severity of the underlying disease and is, accordingly, not well treated by disease-modifying drugs.

Ursodeoxycholic acid is associated with paradoxical itch in some patients. If itch develops or worsens shortly after commencing these treatments, discontinuation or addition of anti-pruritic therapy should be considered.

First-line treatment is colestyramine.[14][15]​​[57]​​ Colestyramine is safe but can be poorly tolerated because of its bitter taste. Adding fruit juice can be helpful. It is important that it be spaced away from ursodeoxycholic acid and all other oral drugs by at least 4 hours, because of the potential for colestyramine to bind to ursodeoxycholic acid and to alter absorption of other drugs and fat-soluble vitamins.

Second-line treatment is instituted if patients are either unresponsive to, or intolerant of, colestyramine. Either rifampicin or naltrexone is recommended.[14][15]​​[58][59]

Rifampicin can cause hepatocellular dysfunction, and it should be introduced cautiously and with liver serum biochemistry monitoring. Deterioration in liver function and elevation of serum liver enzymes with rifampicin are indications for its discontinuation.[58][59][60]​ Patients should also be warned about reddish-orange discolouration of tears, sweat, and secretions.

Some patients may experience an opiate withdrawal-like reaction after starting naltrexone. The dose should be increased gradually.[15]

Selective serotonin-reuptake inhibitors (e.g., sertraline) may be used in the management of cholestatic itch, when patients are unresponsive to the above treatments.[15]

Antihistamines (e.g., hydroxyzine and diphenhydramine) sometimes have a non-specific anti-pruritic effect, which may be due to their sedative properties, but are not recommended as specific therapy; they are, however, useful adjuncts for some.[15]

There are limited series data to support physical approaches to pruritus treatment (using, for example, molecular adsorbent recirculating system [MARS], plasmapheresis, or nasobiliary drainage) in patients resistant to medical treatment. MARS is a proprietary system that can be utilised in conjunction with renal replacement systems to provide an additional albumin dialysis element.

Primary options

colestyramine: 4 g orally once to twice daily

Secondary options

rifampicin: 150 mg orally once daily initially, increase gradually according to response, maximum 600 mg/day given in 4 divided doses

OR

naltrexone: 25-50 mg orally daily

Tertiary options

sertraline: 50-100 mg orally once daily

OR

hydroxyzine: 25 mg orally every 6-8 hours when required

OR

diphenhydramine: 25-50 mg orally every 4-6 hours when required, maximum 300 mg/day

lifestyle modification

Treatment recommended for ALL patients in selected patient group

At present there are no licensed interventions for the management of fatigue in PBC.[14][15]​​​[62]

There are reports associating fatigue with sleep disturbance and with autonomic dysfunction, suggesting that review and modification of lifestyle issues and drugs that may worsen sleep abnormality or autonomic dysfunction is appropriate.[41][42]​ All other treatments for fatigue are experimental.

It is important to identify other disease processes and therapies linked to PBC either directly or indirectly, which may be contributing to the fatigue. These include other autoimmune conditions such as hypothyroidism or autoimmune anaemias, and comorbidities such as type 2 diabetes.[15]

1st line – 

liver transplantation

Liver transplantation is an effective treatment for end-stage PBC. Transplantation is an occasionally indicated treatment for severe and resistant cholestatic itch, if all other treatments have been exhausted.[15][61]

Mayo risk score and Model for End-Stage Liver Disease (MELD) are effective at predicting risk of death in advanced liver PBC and can be useful tools in the timing of transplantation.

Donor organ shortages, and the potential for rapid deterioration to occur in patients with advanced disease, mean that the timing of referral to a transplant unit needs to be considered carefully.

Bilirubin concentration is a useful indicator. Patients with concentrations of 51.3 micromol/L (>3 mg/dL) should be considered for referral to a transplant unit, and patients with concentrations of bilirubin 102.6 micromol/L (>6 mg/dL) should be actively considered for transplantation.

It is now recognised that PBC can recur in the transplanted organ in up to one third of patients.[54]

At present there is no consensus regarding approaches to either the prevention or treatment of post-transplant recurrence, although use of ursodeoxycholic acid in both contexts is widespread. Studies have shown the administration of ursodeoxycholic acid and ciclosporin (a calcineurin inhibitor) may have a role in reducing disease recurrence.​[54][55]​ Further studies in this area are needed.
