PBC and statins

Primary biliary cirrhosis (PBC) is frequently associated with hypercholesterolemia and with an increased cardiovascular morbidity and mortality.

Statins are safe in PBC patients(1)

A trial investigating treatment with low-dose atorvastatin for 12 months was found to be safe in early-stage PBC

• the statin treatment was shown to effectively reduce total cholesterol, LDL-C, LDL triglycerides, and improve vascular function, without affecting cholestasis progression. Therefore, statin therapy should be considered in PBC patients with additional risk factors for cardiovascular disease
• no statistical differences in liver enzymes were observed except a transient increase of alkaline phosphatase

Statins in modulation of disease:

• in a small study (3) simvastatin significantly (P<0.05) reduced serum levels of total cholesterol, LDL cholesterol, alkaline phosphatase, glutamyltransferase, and immunoglobulin M
  • the study authors stated that '..The lipid lowering potency of the HMG-CoA reductase inhibitor simvastatin was confirmed in hypercholesterolemic patients with PBC. The drug might also prove useful as modulator of cholestasis and of immune response in this disease...'
