Primary Biliary Cholangitis
Guidance Statements
Diagnosis
- Biochemical evidence of cholestasis based on ALP elevation.
- Presence of AMA, or other PBC-specific autoantibodies, including sp100 or gp210, if AMA is negative.
- Histologic evidence of nonsuppurative destructive cholangitis and destruction of interlobular bile ducts
3. Liver biopsy to rule out concomitant AIH or other liver disease should be considered in PBC patients when the alanine aminotransferase activity is more than 5 times the upper limit of normal.
4. In cases of suspected PBC/AIH overlap, treatment should be targeted at the predominant histological pattern of injury.
Therapy
6. For patients requiring bile acid sequestrants, UDCA should be given at least 1 hour before or 4 hours after the bile acid sequestrant.
7. Biochemical response to UDCA should be evaluated at 12 months after treatment initiation to determine whether patients should be considered for second-line therapy.
8. Patients who are inadequate responders to UDCA (Table 1) should be considered for treatment with OCA, starting at 5 mg/day.
9. Fibrates can be considered as off-label alternatives for patients with PBC and inadequate response to ursodeoxycholic acid, although fibrates are discouraged in patients with decompensated liver disease.
10. OCA is contraindicated in patients with advanced cirrhosis. This is defined as cirrhosis with current or prior evidence of liver decompensation (e.g., encephalopathy, coagulopathy) or portal hypertension (e.g., ascites, gastroesophageal varices, or persistent thrombocytopenia). Furthermore, we would recommend careful monitoring of any patient with cirrhosis, even if not advanced, receiving OCA.
Management of Symptoms
Pruritis
12. The following agents can be used for pruritus refractory to anion-exchange resins:
a. Rifampicin 150 to 300 mg twice daily.
b. Oral opiate antagonists such as naltrexone titrated to a dose of 50 mg daily.
c. Sertraline 75 to 100 mg daily.
Dry Mouth
a. Artificial tears should be used initially.
b. Pilocarpine or cevimeline can be used in patients for whom symptoms are refractory to artificial tears.
c. Cyclosporine or lifitegrast ophthalmic emulsion can be used in those whose disease is refractory to other agents, preferably under the supervision of an ophthalmologist.
14. The following therapies should be used for xerostomia and dysphagia:
a. Over-the-counter saliva substitutes can be tried.
b. Pilocarpine or cevimeline can be used if patients remain symptomatic despite saliva substitutes.
Management of Portal Hypertension
16.Regular screening for hepatocellular carcinoma with cross-sectional imaging at 6-month intervals is currently advised for men and patients with cirrhosis.
Osteopenia/Osteoporosis
18.Oral alendronate (70 mg weekly) or other effective bisphosphonates should be considered if patients are osteoporotic. Oral bisphosphonates should be avoided if patients have acid reflux or known varices.
Hyperlipidemia
Fat-Soluble Vitamins
Liver Transplantation
Follow-Up of PBC
Liver tests every 3-6 months |
---|
TSH annually |
Bone mineral densitometry every 2 years |
Vitamins A, D, E and prothrombin time annually if bilirubin >2.0 |
Upper endoscopy every 1-3 years if cirrhotic, Mayo risk score >4.1, or transient elastography shows a score ≥17 kPa* |
Ultrasound with or without alpha fetoprotein in patients with known or suspected cirrhosis† and men every 6 months |
Changes from the 2018 PBC Guidelines
Two guidance statements that were published in the 2018 practice guidance on PBC have been revised as follows:
9. Fibrates can be considered as off-label alternatives for patients with PBC and inadequate response to ursodeoxycholic acid, although fibrates are discouraged in patients with decompensated liver disease.
10. OCA is contraindicated in patients with advanced cirrhosis. This is defined as cirrhosis with current or prior evidence of liver decompensation (e.g., encephalopathy, coagulopathy) or portal hypertension (e.g., ascites, gastroesophageal varices, or persistent thrombocytopenia). Furthermore, we would recommend careful monitoring of any patient with cirrhosis, even if not advanced, receiving OCA.
