Abstract
Among 30 consecutive patients diagnosed with primary biliary cirrhosis (PBC) in Taiwan, 27 were females and the median age of symptom onset was 54.5 years. Most had similar clinical manifestations to those reported in the Western countries, but ascites and oesophageal varices as commonly found at the late stages of cirrhosis of liver were noted in nine patients (30%) and 13 patients (43%) respectively. Only one patient was asymptomatic. Hyperbilirubinaemia was noted in 21 patients (70%) and hypoalbuminaemia in 8 patients (27%). All patients had elevated serum alkaline phosphatase and alanine aminotransferase and 28 (93%) had antimitochondrial antibodies. Ten out of 21 patients (48%) were positive in antinuclear antibodies, of which most were of speckled type. Sixteen out of 18 patients (89%) had elevated serum IgM levels. Interestingly, only one of 26 patients (3.8%) was positive for hepatitis B surface antigen, in contrast to its high prevalence (15%) in the Taiwan population. Special associated diseases, including systemic lupus erythematosus, scleroderma, malignant lymphoma and hepatocellular carcinoma, were each noted in one patient respectively. Eight patients had a history of gallstones before the diagnosis of PBC. The mean follow‐up period was 23.6±19.8 months, and nine patients died during that period. In conclusion, the clinical manifestations of PBC in Taiwan are similar to those in Western countries, but most of our cases were at later stages.
