Several
elements of Osteoporosis are held in question or thought of as controversial;
such as the term osteopenia as well as the medications and their use.
The
definition of osteoporosis is porous bone, causing the bone to lose mass and its
supporting structure. The shape of the bone may remain intact until a fracture
occurs. A measurement of -2.5 or more, determined through bone mineral density
testing, is considered to indicate sufficient bone lose to be called
osteoporosis. In 1992, the World Health
Organization (WHO) set measurements of -1.0 to -2.5 to be osteopenic and -2.5
or more osteoporosis. Physicians and
drug companies have since used the designation osteopenia as a pathological
condition of pre-osteoporosis and began treating it with the same medications
used for the severe condition of osteoporosis. Originally, the term osteopenia was
used to identify a group of people who were at high risk of bone fracture; only
the emergence of a problem and not a pathological condition (What is osteopenia?,
n.d.).
Why
is this controversial? The designation
of osteopenia was only to be used to point to a potential problem and not a pathological
condition; however, became a diagnosable condition. The new diagnosis was used for treatment
purposes and has caused the number of women taking osteoporosis medications to
increase substantially. Osteoporosis
went from a rare but serious condition to one that was affecting or potentially
affecting millions of American women (Maxwell, 2011). These women were then prescribed medications
to slow or prevent bone loss; however, did all these women need to take
medications?
Pros and Cons
Cons:
Medications such as Fosamax and Actonel were originally developed to be used
for those diagnosed with osteoporosis (a severe condition) to reduce fracture
risks. Some of the side effects of the medications are serious and do not
necessarily show to be effective in bone loss management in those considered
osteopenic (Murphy, 2009; Maxwell, 2011). These side effects were “heartburn,
indigestion, nausea, inflammation of the esophagus and, in some cases, death of
the jaw bone” and serious
eye problems
(Ramaley, 2008, para. 4; Murphy, 2009). The side effects were thought to be acceptable
to offset the high risk of fracture from osteoporosis. For women diagnosed with osteopenia where the
risk of fracture is lower, these medications may be more than is needed and may
cause harm. There are other means to
control bone loss in those with a slightly lower bone mass with fewer side
effects (i.e. exercise & diet and lifestyle changes). A 2002 study to determine better guidelines
for bone mineral testing and treatments by a federal committee chaired by Al
Berg, M.D., head of the University of Washington's Department of Family
Medicine, “concluded that testing should be targeted to women 65 or older and
that DEXA testing should be limited to the hip” (Ramaley, 2008, para.7). This supported the premise that women were
being overly tested and medicated for this condition.
Pros:
Education on health conditions is the best way to prevent them. Before 1974 only 23% of Americans had ever
heard of Osteoporosis (Maxwell, 2011).
Many American women suffered from this debilitating condition without
relief or forms of treatment. Fracture
rates were high in these older women. These
fractures were considered a normal part of aging. With the WHO setting the standard for
diagnosis and the drug companies’ modes of determining the severity of the condition
and drugs for treatment, fractures and the condition of osteoporosis were
recognized and reduced. The thought of
preventing bone loss in younger women (50 – 65 years old) thus, preventing or
delaying the condition, was the rationale behind the designation of osteopenia.
Recognizing
that DEXA and the current standard deviations are not enough to properly diagnose
fracture risk and osteoporosis; has pointed W.H.O. to develop other tools to
consider lifestyle as well as pathological indicators. The FRAX tool is an online program used to
predict a 10 year probability of hip fracture using individual patient
lifestyle indicators and testing data (Gavalas, 2011). Although, this is not a foolproof tool it
does use more than the bone mineral density score to predict fracture risks. Research
continues to look at better ways to estimate fracture risks and diagnosis osteoporosis
more accurately.
Controversy
is a positive part of research. It is a motivator to continue to study and
review conditions, treatments, and methods of determination of any new or
current disease designation.
