We studied 20 female patients, aged 51 +/- 13.6 years old, with the diagnosis of Primary Biliary Cirrhosis (PBC) to assess osteopenia, main involved sites and its relation to menopause, some parameters of mineral metabolism and the degree of histological liver involvement. The diagnosis of PBC was based in histological, clinical and laboratory features. Bone densitometry was measured with a dual-photon densitometer and compared with values of a normal female population from the laboratory. When compared to controls, studied patients had a significantly lower lumbar spine bone density and total bone mineral content and a non significantly lower density in femoral neck and total body. Serum calcium, phosphorus, magnesium, PTH and urinary calcium/creatinine ratio were within normal limits. Lumbar spine density was not significantly lower in patients with more severe liver histological involvement and in postmenopausal women. No correlation was found between the duration of postmenopausal period and the degree of osteopenia. It is concluded that patients with PBC have a clear lumbar spine osteopenia and a lower total mineral content and that these parameters worsen in a non significant fashion in subjects along with liver histological involvement and with the length of post menopausal period.

UI MeSH Term Description Entries
D008105 Liver Cirrhosis, Biliary FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cholangitis involves the destruction of small intra-hepatic bile ducts and decreased bile secretion. Secondary biliary cholangitis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D015519 Bone Density The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
