Pulmonary function abnormalities are common in primary biliary cirrhosis (PBC) patients, particularly those with symptoms. Reduced diffusion capacity was frequently observed, suggesting significant lung involvement in this liver disease.

Area of Science:

  • Hepatology
  • Pulmonology
  • Internal Medicine

Background:

  • Primary biliary cirrhosis (PBC) is a chronic liver disease.
  • Pulmonary complications can occur in PBC patients.
  • The extent and nature of lung function abnormalities in PBC are not fully understood.

Purpose of the Study:

  • To investigate pulmonary function abnormalities in patients with primary biliary cirrhosis.
  • To compare lung function in PBC patients with healthy controls.
  • To identify factors associated with lung impairment in PBC.

Main Methods:

  • Pulmonary function tests were performed on 25 PBC patients.
  • Results were compared to 17 age- and sex-matched healthy subjects.
  • Patients were categorized based on symptoms and presence of chronic obstructive lung disease.

Main Results:

  • 56% of PBC patients exhibited lung function impairment.
  • Reduced diffusion capacity was observed in 36% of PBC patients, significantly more than controls.
  • Abnormalities were more prevalent in symptomatic PBC patients (72%) compared to asymptomatic ones (14%).
  • Obstructive lung disease was present in four patients.

Conclusions:

  • Lung function impairment, especially reduced diffusion capacity, is common in PBC.
  • Symptomatic PBC patients are more likely to have pulmonary abnormalities.
  • The lung findings in PBC resemble those seen in sarcoidosis.
