Additional Associations and Complications

Associations and potential complications of primary biliary cholangitis (PBC) may extend beyond symptoms of pruritus, fatigue, and depression and may include the following:

  • Thyroid disease1
  • Systemic sclerosis including its variant, CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia)1,2
  • Celiac disease1
  • Osteoporosis2
  • Hyperlipidemia2
  • Renal tubular acidosis2
  • Malabsorption of fats, resulting in steatorrhea and fat-soluble vitamin deficiency (uncommon except in the late stages of the disease)2
  • Portal hypertension2
  • Ascites2
  • Variceal hemorrhage2
  • Hepatic encephalopathy2
  • Jaundice2
  • Liver failure2

Other potential complications

  • Additionally, as many as one-third of patients with PBC are diagnosed with another autoimmune disease. The most frequent concomitant diseases include Raynaud syndrome, rheumatoid arthritis, autoimmune thyroid disease, and Sjögren syndrome5,6

aIn a study of 1032 patients, the NIH enrolled patients from 23 tertiary referral centers for liver diseases in the United States. Random digit-dialed controls (n=1041) were matched for sex, age, race, and geographical location. The study evaluated associations between the rates of comorbidity in affected individuals.3
