- Original description
Osteoporosis is a health problem of major proportions. It affects more than 40 million Americans and results in more than 2 million fractures annually among Medicare patients alone. Hospital admissions for osteoporotic fractures exceed those of heart attacks, strokes and breast cancer combined. Osteoporosis is commonly considered a disease associated with menopause. This estrogen deficiency related bone loss is characterized by high bone turnover with increased resorption without commensurate changes in bone formation. It is in contrast to age-related bone loss, which starts as early as in the fourth decade of life and continues with increasing age. Age-related bone loss is usually associated with lower bone turnover and decreased bone formation is the main abnormality.Read full original descriptionShow less
Novel Precision Medicine Approach to Treatment of Osteoporosis Based on Bone Turnover - Follow Up Study
Osteoporosis is a health problem of major proportions. It affects more than 40 million Americans and results in more than 2 million fractures annually among Medicare patients alone. Hospital admissions for osteoporotic fractures exceed those of heart attacks, strokes and breast cancer combined. Osteoporosis is commonly considered a disease associated with menopause. This estrogen deficiency related bone loss is characterized by high bone turnover with increased resorption without commensurate changes in bone formation. It is in contrast to age-related bone loss, which starts as early as in the fourth decade of life and continues with increasing age. Age-related bone loss is usually associated with lower bone turnover and decreased bone formation is the main abnormality.
Current therapies do not address age-related bone loss and the special needs of the age-related osteoporosis population is currently ignored. This is to a great degree due to difficulties associated with the bone biopsy necessary for unequivocal determination of bone turnover status. Thus, the current standard of care relies on starting with an antiresorber, which is of limited effectiveness in age-related osteoporosis, and in fact impedes the effectiveness of the appropriate anabolic medication. In a current ongoing study - Novel precision medicine approach to treatment of osteoporosis based on bone turnover. EIRB#70781; efforts are focused on addressing this particular problem.
Our follow-up study seeks to achieve one specific aim: to compare effectiveness of Alendronate vs Teriparatide after participants have been switched at the end of treatment at year one, to the other drug at year two for the same duration of treatment.
Inclusion: Diagnosed Osteoporosis by DXA (BMD t-score = -2.5 with or without fragility fractures); Prior enrollment and completion of therapy in the "Novel precision medicine approach to treatment of osteoporosis based on bone turnover" trial.3) Premenopausal, menopausal, and post-menopausal females; 45 years old and older; Normal levels of Vitamin D; Absence of all exclusion criteria on clinical workup. Patients diagnosed as osteoporotic due to the presence of.
Exclusion: Planned or anticipated oral surgery within the next 12 months; Chronic alcoholism and/or drug addiction; Prior radiation therapy (external beam or implant radiation) involving the skeleton (only if randomized to the bone forming drug (anabolic Forteo®)); Systemic illnesses or organ diseases that may affect bone (except type 1 or type 2 diabetes mellitus); Clinical condition that may limit study participation (e.g., heart diseases (unstable angina), lung diseases (severe COPD), other infections); Abnormalities of the esophagus (tube connecting the mouth to the stomach) which delay esophageal emptying such as stricture (narrowing) or achalasia (a condition that prevents normal swallowing); Have a history of malignancy (cancer), not including non-melanoma skin cancer; Have other bone diseases that are not linked to age or menopause; Pregnant or trying to become pregnant or are breastfeeding; Use of systemic anticoagulation (blood thinner); Planning to move out of the area within 18 months of the study; Inability to stand or sit upright for at least 30 minutes; Vitamin D (Calcidiol) level below the normal range (below 20ng/mL).
