Complementary and Alternative Medicine, Dietary Supplements, and Medications
CAM- Where is it? • A 14 yr old athlete with moderate, persistent asthma comes to clinic. He has an asthma action plan and has been adherent with his controller medication. Now he wants to try a breathing technique (Buteyko) so he can “get off” his meds. • A 3 yr old comes to the clinic for a well-child check-up. On exam you find a right otitis media. She is asymptomatic and you recommend watchful waiting. The parents would like to try a homeopathic remedy because they had heard that homeopathy worked better than placebo for children with an ear infection. Answer: Everywhere

Complementary and Alternative Medicine (CAM) • Complementary and alternative medicine • A group of diverse medical and health care systems, practices, and products • Not considered part of conventional medicine • Some scientific evidence exists regarding CAM therapies • For most, questions of safety and efficacy persist • Complementary medicine is used together with conventional medicine. Alternative medicine is used in place of conventional medicine. http://nccam.nih.gov/health/whatiscam/
Integrative or Holistic Medicine • Integrative combines mainstream medical therapies and CAM therapies for which there is some high-quality scientific evidence of safety and effectiveness. • “Healing-oriented medicine that takes account of the whole person (body, mind, and spirit), including all aspects of lifestyle. It emphasizes the therapeutic relationship and makes use of all appropriate therapies, both conventional and alternative.” http://nccam.nih.gov/health/whatiscam/ http://www.integrativemedicine.arizona.edu/about2.html
Major Classes of CAM Enhance the mind’s capacity to affect bodily function and symptoms • Chiropractice • Osteopathy • Massage Alternative medical systems Mind-body interventions Biologically -based therapies Manipulative & body-based methods Energy therapies • Homeopathic • Naturopathic • Traditional Chinese and Ayurvedic treatments • Dietary supp • Herbs • Foods • Vitamins • Natural • substances • Biofield therapy • Bioelectro- • magnetic • therapy http://nccam.nih.gov/
CAM Utilization Reasons for using CAM: • Consistentwith patient’s and families values: natural, and empowering • CAM providers are “patient-centered”, dedicated to promotinghealth. • Conventionaltherapies are perceived to be emotionally or spiritually without benefitConventional therapies are not effective or are associatedwith side effects. • CAM use is a circular: usage determines number of CAM practitioners

Conventional Medicine, Evidence? • Most conventional physicians believe in unconventional medicine because it is not scientific • What is evidence-based medicine? Treatment that will improve patient outcomes by well-designed, appropriately powered, randomized, controlled clinical trials. • There is not good evidence (Grade A) that many of the commonly used therapies in conventional medicine are effective (ex: heparin, aspirin, and warfarin). • The principal distinguishing characteristic of unconventional and conventional medicine therapies is the source of introduction. • Conventional therapies are introduced by mainstream Western physicians and scientists, whereas most unconventional modalities are introduced by "outsiders." • One of the reasons that most unconventional modalities are not evidence based is that the majority of them were introduced prior to the 20th Century
Whole Medical Systems Complete systems of theory and practice that evolved independently Traditional systems of medicine that are practiced by individual cultures throughout the world Includes traditional Chinese medicine, Ayurvedic medicine, homeopathy, naturopathy

Biologically Based - Supplements What is a supplement? Regulated by FDA http://www.fda.gov no requirements for FDA testing manufacturers responsible for ensuring product safety label requirements safety alerts: http://www.cfsan.fda.gov/~dms/ds-warn.html
Energy Medicine Veritable - energy that can be measured Includes sound, visible light, magnetism Putative – energy that has yet to be measured human beings are infused with a subtle form of energy Includes qi (ki in Japanese); doshas; prana, homeopathic resonance
Energy Medicine - Acupuncture Few complications Scientific evidence? post chemotherapy management of nausea pain relief NIH Consensus Statement (1997) http://consensus.nih.gov/1997/1997Acupuncture107html.htm

Clinical Trials and CAM Why are there so few CAM clinical trials? Drug companies have to do studies to go on the market—supplement companies do not, so clinical trials sponsored by supplement companies are rare Alternative treatments are often customized for a specific person. Clinical trials try to prove something works for most people. Belief systems of some CAM practitioners do not agree with the idea of Western studies, so they do not participate CAM has only recently become “legit” in the scientific community
Dietary Supplements RUN THE WHOLE GAMUT!!! vitamins- C, E. minerals- Ca, Se amino acids-lysine fats- fish oil hormones- DHEA herbs- ginseng phytochemicals-garlic etc
FDA Regulations Protect Consumers • FDA regulates: Drugs are highly regulated by FDA • Vitamins & minerals regulated as foods • Supplements are considered safe until demonstrated to be hazardous by FDA • Herbals & botanicals totally unregulated
Who Benefits?Those at risk for developing nutritional deficiencies only! • People with vit, mineral deficiency • Vegans- vit D, B12 • Pregnant women- folate • Elderly persons- B12/folate • People at risk of osteoporosis- Ca, vit D • People at risk of losing blood- Fe • People on restricted diets- vit, minerals
Hormones • HGH • EPO • BHCG • Steroids
Human Growth Hormone • Normally secreted by the pituitary • Normal function of GH is growth and development of every body system, including bone and muscle • Can be stimulated by propanolol, vasopressin, clonidine, and levodopa • Synthetic growth hormone
Side Effects: • Acromegaly (may be irreversible) • Peripheral Neuropathy • Coronary Artery Disease • Cardiomyopathy • Diabetes, Hypothyroidism, arthritis • No available urine test available, but banned by NCAA and IOC
Erythropoietin • Hormone released by the kidneys in response to low Hct • Stimulates RBC production from bone marrow • Has recently been manufactured by recombinant DNA technique • Can increase Hct in renal patients by up to 35%, lasting up to 7 months • Used most by cyclists
Blood Doping • Induced Erythrocythemia: An increase in Hb following reinfusion of an athlete’s blood • Goal: to increase the oxygen-carrying capacity of Hb • Has been used as far back as 1947 • 1984: seven US Olympic cyclists guilty • Banned by IOC in 1985
Detection: • Blood doping and Erythropoietin: banned by IOC • No known urine test to detect • Testing: Measured Hct >50 • Measurement of serum Fe and Bilirubin to detect hemolysis after frozen PRBC transfusion
