Vitamin D deficiency is associated with subclinical carotid atherosclerosis: the Northern Manhattan study.

Background And Purpose: The purpose of this study was to assess the association of vitamin D deficiency and indices of mineral metabolism with subclinical carotid markers that predict cardiovascular events.

Methods: Two hundred three community-dwelling adults (Northern Manhattan Study; age, 68 ± 11; age range, 50 to 93 years) had serum measurements (calcium, phosphorus, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, parathyroid hormone) and carotid ultrasound (plaque presence, number, maximal carotid plaque thickness, intima-media thickness).

Results: Adjusting for cardiovascular risk factors, plaque number was associated with phosphorus levels (β=0.

Normal vitamin D and low free estradiol levels in women on enzyme-inducing antiepileptic drugs.

Relationships between reproductive hormone levels, bone turnover marker levels, bone mineral density, and rates of bone loss were evaluated in premenopausal women with epilepsy taking enzyme-inducing antiepileptic drugs (EIAEDs: phenytoin or carbamazepine) or lamotrigine. Calciotropic and reproductive hormone levels, bone turnover marker levels, and bone mineral density were measured at baseline and 1 year. Bone mineral density did not differ between groups.

Low bone mass and high bone turnover in postmenopausal human immunodeficiency virus-infected women.

Context: Low bone mineral density (BMD) is commonly reported in young men and women with HIV infection, and fracture rates may be higher. With effective antiretroviral therapy (ART), the HIV population is aging. However, little is known about the skeletal status of postmenopausal women.

Characteristics of elderly patients admitted to an urban tertiary care hospital with osteoporotic fractures: correlations with risk factors, fracture type, gender and ethnicity.

Osteoporosis is a major public health problem in the United States of America and around the world, largely due to the morbidity and mortality associated with osteoporotic fractures. In the past decade, large epidemiologic studies have contributed greatly to our understanding of patients who fracture. However, most studies are limited to postmenopausal white women.
