Guiding Patients on Safe and
Effective Use of Complementary
Medicine and Integrative Medicine –
Nicole Nisly, M.D.
What is CAM

CAM: Complementary and Alternative
Medicine
 a group of diverse medical and health
care systems, practices, and products
that are not generally considered part
of conventional medicine.
 CAM practices are often grouped into
broad categories, such as natural
products, mind and body medicine.
Integrative Medicine

Integrative Medicine:

Integrative Medicine is the practice of medicine
that reaffirms the importance of the relationship
between practitioner and patient, focuses on the
whole person, is informed by evidence, and
makes use of all appropriate therapeutic
approaches, healthcare professionals and
disciplines to achieve optimal health and
healing

Gerry A




56 year old man with recent diagnosis of locally
advanced pancreatic cancer, status post Roux en Y
surgery, prognosis < 6 months
Presented to CAM clinic to address use of
Complementary therapies in the setting of cancer
care.
Planned to follow oncologist’s recommendations
but also use CAM
“I have a feeling that my mission here is not
complete, I need your help”
Why should I address CAM or
consider Integrative Medicine
High utilization: coordination of care
 Potential for interactions and side-effects
 Patient’s trust, partnership and engagement
 Brings values and culture to health care
 Increased patient satisfaction
 Importantly: you may be surprised that
many benefits can be afforded by safe and
effective use, enhancing traditional care

Gerry’s regimen




A plant centered diet: morning burritos laced in onions,
garlic and spices, meditation, yoga, biking, guided
imagery, writing/blogging. No ETOH, smoking,
occasional coffee with minimal honey/unrefined sugar
No sugar, white flour, animal fat. Multiple servings of
plants daily (despite low income). Occasional coffee
Dietary supplement regimen was extensive and changed
regularly.
He researched the lay and scientific lit for new studies
daily, followed Drs Weil, Oz and other prominent CAM
figures
Criteria for advice on CAM





Recommend
 Evidence supports safety and efficacy
Accept, or discuss as option AFTER standard of
care or evidence-based treatment offered
 Efficacy is inconclusive, but safety is established
Discourage
 Evidence indicates inefficacy or serious risk
Discuss FDA approval, risks, document and follow
Know the evidence, keep personal beliefs in check,
you bring the evidence-based care, medical
knowledge and are responsible for safety and
efficacy and following the standards of care.
Gerry’s Medical Visit


“I read that cancer needs sugar, how about the use
of insulin and hypoglycemic therapy”
 Unsafe and not plausible to be effective,
however you could eliminate most simple and
refined sugars in your diet
Regarding neuropathy due to cancer treatment, I
would like to use high dose Vitamin B6
 I think Alpha Lipoic Acid has better data of
safety and efficacy for neuropathy and you
could use Vitamin B6 at higher than RDA but
no higher than UL, we will monitor levels
Gerry A - follow up
I knew him for over 5 years
 He went through 3 recurrences
 He died in his sleep presumably due to GI
bleeding at anastomotic site
 He came to CAM clinic every month and
discussed treatment and CAM use
 He rode his bike to clinic
 He spoke with my medical students
regularly and with other patients


New Requirements



Manufacturers are expected to follow "good manufacturing
practices" (GMPs) to ensure that dietary supplements are
processed consistently and meet quality standards.
Requirements for GMPs went into effect in 2008 for large
manufacturers and are being phased in for small
manufacturers through 2010.

Dietary Supplement Use National
Surveys

12 of children had used some form of CAM,
with 20% using a "natural products" (i.e.,
dietary supplements other than vitamins and
minerals) in the past 12 months. (National

 too expensive
 too focused on
curing vs
maintaining health
CAM perceived as:


less authoritarian,
empowering
congruent with
patient’s values
and personal
beliefs

Vitamin D facts





Fat soluble vitamin, the sunshine vitamin
Produced endogenously when ultraviolet sunrays
strike skin and trigger Vitamin D synthesis
It must be metabolized first in the liver to make
25-OH vitamin D and then kidney to make 1,25
OH vitamin D
Besides calcium absorption it modulates cell
growth, neuromuscular and immune function and
reduces inflammation
25-OH vitamin D best indicator of nutritional
status
Vitamin D and Cancer Care
Levels: in ng/mL <20 insufficient; 20-50
optimal; @50 potentially associated with
improved outcomes
 Amount needed for non obese adults who
are younger than 70: 600-800 IU daily
 Upper Tolerable Intake 4,000 IU daily
 Measure and target levels between 3050ng/mL (IOM/NCCAM)

Melatonin
Natural hormone produced in the body,
rises in the evening and lowers in the

 Most studied for jet lag, delayed sleep phase

Acupuncture Use in Pain



Acupuncture, among the oldest healing practices in the world, is part of
traditional Chinese medicine. In Acupuncture practitioners stimulate
specific points on the body—most often by inserting thin solid needles
through the skin. In traditional Chinese medicine theory, this regulates
the flow of qi (vital energy) along pathways known as meridians.
In the 2007 National Health Interview Survey, 1.4 percent of respondents
(an estimated 3.1 million Americans) said they had used acupuncture in
the past year.
Analysis of acupuncture data found that pain or musculoskeletal
complaints accounted for 7 of the top 10 conditions for which people use
acupuncture. Back pain was the most common, followed by joint pain,
neck pain, severe headache/migraine, and recurring pain.
Indications for acupuncture






Carpal tunnel syndrome, Fibromyalgia, Myofascial pain: mixed limited
data
Headache/migraine: A 2009 review found that acupuncture may help
tension headaches, however with migraines no difference found.
Low-back pain: According to clinical practice guidelines issued by the
American Pain Society and the American College of Physicians in 2007,
acupuncture is one of several CAM therapies physicians should consider
when patients with chronic low-back pain do not respond to conventional
treatment. RCT in 2009 found that actual acupuncture and simulated
acupuncture were equally effective and both were more effective than
conventional treatment for relieving chronic low-back pain.
Menstrual cramps, Neck pain, Tennis Elbow, Post-op dental pain:
promising but not definitive
Osteoarthritis/knee pain—Acupuncture appears to be effective for
osteoarthritis, particularly in the area of knee pain..
