Bone disorders in chronic liver disease Collier JHepatology 2007[Oct]; 46 (4): 1271-8Osteomalacia rarely occurs in adult patients with chronic liver disease despite a low serum vitamin D level being reported in up to two-thirds of patients with cirrhosis. In contrast, osteoporosis, which increases the risk of vertebral fractures, occurs in 12%-55% of patients with cirrhosis. Although the prevalence is probably falling, as shown by a fall from 57%-26% in patients with biliary disease requiring liver transplantation over the last 2 decades, it still accounts for significant patient morbidity. Bone density also falls in the first 3 months after liver transplantation, and pretransplant fractures are predictive of posttransplant fractures. Many of the known risk factors for postmenopausal osteoporosis exist in the cirrhotic population, such as excess alcohol intake, steroid use, poor nutrition, and hypogonadism. There is also an increased risk of osteoporosis in patients without cirrhosis, particularly those with hemochromatosis and biliary disease. The diagnosis is made with bone density measurements. The effective treatment is largely based on evidence from postmenopausal osteoporosis as there have been only a few small clinical trials of patients with chronic liver disease. Bisphosphonates are the mainstay of treatment; they have been shown to be effective in biliary disease and are well tolerated.|Bone Density/physiology[MESH]|Bone Diseases/*etiology/physiopathology[MESH]|Chronic Disease[MESH]|Humans[MESH]|Liver Diseases/*complications/physiopathology[MESH]|Osteomalacia/etiology/physiopathology[MESH]|Osteoporosis/etiology/physiopathology[MESH]|Risk Factors[MESH] |
