Contrast-enhanced MRI and FibroScan can be used with comparable results for the assessment of liver fibrosis in patients with PBC and seem to supplement each other. MR-spectroscopy represents the best method for highly accurate noninvasive measurement of liver steatosis.

In non-cirrhotic, early-stage, primary biliary cirrhosis the 13C-methacetin breath test and the 13C-galactose breath test reliably indicate decreased liver function. The 13C-galactose breath test can also predict the histological score.

Treatment of primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) with ursodeoxycholic acid (UDCA) has been in common use since 1985. In PBC, treatment with UDCA improves laboratory data, liver histology, enables a longer transplantation-free interval and prolongs disease survival. Because UDCA is unable to cure the disease newer drugs or combination therapies are still needed. Studies with UDCA and immunosuppressants such as prednisone, budesonide and azathioprine have shown that in selected patients combination therapy may be superior to UDCA monotherapy. PSC is treated successfully with UDCA and endoscropic dilatation of the bile duct strictures. Treatment of extrahepatic manifestations of cholestatic liver disease such as pruritus, fatigue, osteoporosis and steatorrhea can be problematic and time-consuming.

Sulindac in combination with UDCA further improves liver biochemistries in patients with PBC who responded incompletely to UDCA alone.

A 22-year-old man without pre-existing medical conditions presented to our hospital with a progressive reduction of his physical overall performance, muscle weakness of the extremities, and diarrhea for the last 2 months concomitant with elevated liver enzymes and creatine kinase activity. After ruling out infectious diseases, neoplasia, and autoimmune disorders as a cause of these symptoms, the histology of liver and muscle samples led us to suspect a diagnosis of a rare lipid metabolism disorder. Molecular biologic testing provided the diagnosis of multiple acyl-coA dehydrogenase deficiency with ubiquinone deficiency and late onset. The course of disease was complicated by liver failure and severe pneumonia requiring ventilatory assistance. With the substitution of riboflavin and ubiquinone, the patient showed a gradual recovery of his clinical presentation and an improvement of his laboratory tests. A congenital lipid metabolic disorder might be a rare cause of severe myopathy and hepatopathy in a young adult.
