Presented by: Nicole Nisly, MD About Today’s Presentation • I will discuss osteoporosis and focus on causes, treatment options and prevention • I will discuss medications and life style choices that can be of help • I will discuss some treatments that are not FDA approved • I have no conflict of interests to disclose About Dr. Nisly • Hello, my name is Dr Nicole Nisly, thank you for coming today • I am a Professor of Internal Medicine and work at the University of Iowa Iowa River Landing Clinic (319/467-2000) • My areas of expertise include Internal Medicine Primary Care, Complementary and Integrative Medicine, LGBTQ Health and Cultural Diversity in Health How do we get osteoporosis? • We reach our maximum bone mass normally by the age of 40 • As we age, we tend to lose bone mass, especially after menopause • Certain conditions make that loss happen faster Risk Factors for Osteoporosis http://www.shef.ac.UK/FRAX • Age (most fractures of the hip occur after age of 80) • Use of corticosteroids • Low Body weight • Smoking • Excessive alcohol use • Parental Hip Fx • Rheumatoid arthritis • • • • • • Previous ‘Fragility” fractures Malabsorption Early menopause Hypogonadism Chronic liver disease Inflammatory Bowel disease How do we know if we have osteoporosis? • For most women, they should be screened with a DEXA scan at age 65 • Sooner with increased risk factors (FRAX calculated risk of over 20% over 10 years) • For men: less certain but around age 70, sooner if at risk About DEXA Scan Results (dual energy xray absorptiometry) • This test measures bone mineral density (BMD). • T score compares your BMD to that of a young women around age 25 • Z score compares your BMD to someone of your age • Osteoporosis: T score of 2.5 or less SD • Osteopenia: T score between 1-2.5 SD • Z score of 2 or lower SD is abnormal How often do you test? • For women at average risk and T score between 2-2.49 SD or any risk factors, repeat every 2 years • T score between 1.5-1.99 SD, repeat in 3-5 years • T scores at 1-1.49 SD, repeat in 10-15 years • Address risk and benefit, including cost. The purpose of testing is to help decide when to treat and reduce risks Should I test early? • If you have the risk factors indicated previously or fragility fracture: test women starting at age 50 and men around 70 • Canadian osteoporosis Society recommends earlier testing for women and men between 5065 How to test? • DEXA scan of Hip and Lumbar spine preferred • Peripheral measurements of heel or ultrasound measurements while more available do not correlate well with fracture risk • Bone turnover markers are not cost effective in guiding evaluation or treatment Other Tests • Calcium • Biochemistry profile including Albumin and protein and Alkaline Phosphatase • 25-OH vitamin D • Complete Blood Count • Other tests in certain situations: • Cortisol, parathyroid hormone, celiac disease screening, 24 hr urinary calcium Pre-Menopausal Women & Children • Bone density testing should only be done in very specific situations of very high risk • Use Z scores instead of T scores to interpret test • Usual WHO guidelines apply to post menopausal women How about prevention? • Increase exercise and weight lifting, aim at 3 times per week for 30 minutes • Balance and fall prevention is important, exercises such as Tai-Chi may help • Gluten Free Diet and Low or High protein diet are discussed for specific cases • Vitamin D 3 in gel capsule: 600-4,000 IU daily (most people 600-1,000) • Calcium: diet is best source. Supplements The Issue of Calcium • Dietary sources: one serving of dairy: 300 mg 1 oz hard cheese, 8 oz of milk, 6 oz of yogurt) Greens, non dairy drinks • Supplements: calcium citrate absorbs better if using certain medications • Goal: 500-1,000 mg of supplement if needed Medications • Biphosphanates such as Alendronate, Risendronate, Ibandronate and the I.V. form of Zoledronic Acid increase bone mass and reduce fracture • SERM such as Raloxifene can decrease bone loss and reduce vertebral fracture • Others: parathyroid hormone shots, Strontium (not available in the US), Denosumab shots, calcitonin Natural Therapies • • • • • Tai chi Soy protein Ipriflavone (unproven) Previously discussed life style changes Environmental modifications such as night lights, removing rugs, using walkers, exercising regularly • QUIT SMOKING!! • Reduce alcohol What is CAM anyway? • A wide range of practices, new and old, at times safe, other times dangerous, widely used by patients worldwide, however… • In general, safety and efficacy are not yet well established, • Not commonly taught in medical schools and • Not commonly utilized in U.S. hospitals However… • Integrative Medicine and various Complementary or Holistic Therapies are making their way into the health care system in various formats • Education: Core Curriculum, Electives, Resident electives, Fellowships are growing in the U.S. Selected Alternative Medicine Systems and Techniques • Mind-body interventions • Alternative systems of medical practice • Biologically based therapies • Manipulative and body-based methods • Energy therapies Mind-body Interventions • Art therapy • Biofeedback • Dance/movement therapy • Hypnosis • Imagery • Meditation • Music therapy • Prayer and mental healing • Self-help support groups • Yoga Alternative Systems of Medical Practice • Acupuncture • Homeopathy • Ayurveda • Naturopathic medicine • Community-based • Traditional chinese medicine – Latin American community healthcare – Native American healthcare Why bother telling your doctor or pharmacist what will they do with that information? • Integrated care vs. uncoordinated care • Potential for: – Side-effects – Drug-dietary supplement interactions – Benefits Herbal Medicines • • • • • European Botanical Medicines Latin American Herbal Remedies Native American Herbal Agents Ayurvedic Herbal Agents Oriental Herbal Agents – Chinese – Japanese - Kampo Medicine Derived From Plants • • • • • • • • • • • • Aspirin Atropine Belladonna Capsaicin Cascara Cocaine Colchicine Digoxin Ephedrine Ergotamine Ipecac Opium • • • • • • • • • • • • Physostigmine Pilocarpine Podophyllum Psyllium Quinidine Reserpine Scopolamine Senna Taxol Tubocurarine Vincristine Vinblastine Klepser, 2000 St. John’s Wort • Drug Interactions (P450 1A2, 2C9, 3A4) • Activates a receptor, named PXR, in the liver and intestine, which accelerates drug metabolism. • It may interact with over 80% of drugs available in the U.S. market. I have a cold, allergy or something… • Mr. Sneezy comes in for refill of his allergy medication. • Typically he has symptoms during the ragweed season. • I have frequent colds, can I use Echinacea, he asks? Where do I go for reliable information? • NCCAM (http://nccam.nih.gov/) • ODS (http://ods.od.nih.gov/index.aspx) • NCI/OCCAM (http://www3.cancer.gov/occam/) – MD Anderson database (http://www.mdanderson.org/departments/CIMER/) • Natural Medicine Comprehensive Database (www.naturaldatabase.com) • Micromedex • Consumerlab.com Talk to your Doctor • Tell your health care providers about all the complementary and alternative practices you use. This will help ensure coordinated and safe care. • Be proactive. Don't wait for your health care providers to ask about your CAM use. • Make the most of the conversation. Bring a list of everything you use, keep a record of the information you receive, and ask questions if something is unclear. Using Supplements • Why I want to take the supplement • How I found out about it • Is it safe for me to take? Will it interact with any of my medications? • Is it likely to help me? • What else should I know about it? Where can I find more information? • Should I try this? If not, why not? Might something else be better?
