“…After 6 years of follow-up, the patients with overlap had significantly worse clinical outcomes than the nonoverlap PBC patients, thus confirming the potential importance of using liver biopsy to establish the correct diagnosis. 23 It was recognized that in one study, the presence of AMA and cholestatic enzymes in a middle aged woman had a 98% positive predictive value for the presence of PBC, 3 obviating the need for a liver biopsy for diagnostic purposes. However, this study was conducted and validated in centers of excellence for PBC by experienced investigators.…”

“…It is less useful in assessing improvement in patients with mild to moderate disease, a group which may actually be the most responsive to therapy. Response of ALP to therapy has been shown to be a good correlate of both survival 17 and liver histology 3 in PBC and is used globally in clinical practice to predict the progression of the disease; it is therefore an acceptable therapeutic criterion to monitor PBC treatment. Analysis of UDCA trials demonstrated that normalization of ALP, when assessing a large group, was associated with better survival than expected.…”

“…In fact, some have proposed that, although a diagnosis of AMA-positive PBC can be made without a liver biopsy, a diagnosis of AMA-negative PBC cannot be made without one. 25 It is estimated that approximately 5% to 8% of cases of PBC are negative for AMA. 13,18,21 These patients follow a clinical course similar to that of AMA-positive patients.…”

“…• The need for liver biopsy in all patients with primary biliary cirrhosis and primary sclerosing cholangitis. In most cases the diagnosis can be established without liver biopsy on the basis of a cholestatic pattern of liver chemistries and either antimitochondrial antibodies in primary biliary cirrhosis [23] or cholangiography in primary sclerosing cholangitis [24]; scoring systems based on readily ascertained clinical variables can be used to assess prognosis and response to therapy [22,23]. • The need for protocol liver biopsies in all liver transplant recipients.…”
