Although there
is still no cure for diabetes, treatment options are now
better than ever, whether a person has type 1 or type 2
diabetes, all thanks to the marriage of modern medicine
to modern technology. Areas such as self-monitoring
blood glucose levels and administering insulin have seen
the most significant improvements. Self-monitoring is a
key component of successful diabetes management, and
refers to the blood glucose/sugar test that a person
does themself. The test has always been done by pricking
a finger and applying a drop of blood to a strip, with
the strip then inserted into a portable machine for
interpretation of the levels of blood sugars and/or
ketones. The newest blood glucose meters allow for
testing from alternative sites other than the
fingertips, such as from the upper arm, forearm, base of
the thumb, and from the thigh. These sites tend to be
less sensitive than the fingertips, and are a desirable
alternative especially when testing children. However,
as promising as these new monitors seem to be, they may
have some drawbacks. There’s a possibility of the blood
test not being as accurate when samples are gathered
from alternative sites as opposed to samples taken from
the fingertips. The reason for the difference is because
the concentration levels of glucose may be quite
different in other areas of the body than from the
fingertips. Concentrations of glucose levels tend to
change rapidly after meals, insulin or exercise, and
alternative sites for glucose monitoring may show any
changes more slowly than when blood is drawn from the
fingertips. If you are using an alternative glucose
monitoring device, be sure to still check glucose levels
from the fingertips if you think your blood sugar is
low, if you are still unsure of what your symptoms are
when you become hypoglycemic (low blood sugar level), or
if the results do not agree with the way you feel.
Although it’s
been around for over 25 years, continual advancements
and improvements have made the insulin pump a great
option for children and adults who must give themselves
daily insulin injections. The pump is usually worn
discreetly on a belt/waistband, in a pocket, or under
clothing, and there are a variety of clips, cases and
fashion accessories to help make the pump easy to wear.
No larger than a pager, the insulin pump contains a
cartridge filled with fast-acting insulin, and can be
programmed by the pump’s internal computer by the person
wearing it, accessible by a screen and several buttons.
Once programmed, a precise motor pushes insulin from the
cartridge through a tube and into the body. The tubing
that connects the pump to the body comes in various
lengths (from 24” to 42”) and is quite durable. To get
the insulin under the skin, an infusion set is worn,
which uses a metal insertion needle (about the size of
an insulin syringe needle) to insert a tiny, flexible
plastic tube into the fat just beneath the skin. The
infusion set is usually placed into the abdomen,
buttocks or hip area. After insertion, the metal needle
is removed and the infusion set is then taped securely
in place. A new infusion set is inserted every 2 to 3
days, depending on individual usage. When the infusion
set is inserted properly, it usually won’t be felt or
noticed the entire time it’s worn. Most infusion sets
have a quick disconnect mechanism, allowing the user to
temporarily unhook the pump and tubing for bathing,
swimming, contact sports or intimacy, and afterward, the
pump can be reconnected with a simple click.
New, improved
pumps also have multiple safety features that ensure
against accidental insulin delivery. All insulin pumps
run multiple safety checks every second and have
sensitive alarms that detect problems such as blocked
insulin flow and programming errors. Because the pumps
set off an alarm and “lock up” in the event of any
internal problem, there is virtually no chance of
accidental insulin delivery. They allow for people with
diabetes to effectively deal with changes in their
activity levels, busy schedules, changes in diet, and
changes in blood glucose level because of hormonal
changes. This is one reason why they are being
prescribed with greater frequency for young children and
young adults, since their activity levels and diet
levels change frequently. Although these new pumps work
great, it is still important to continue to take blood
samples in order to monitor your glucose levels. Insulin
pumps tend to be a bit pricey - between $4,000 and
$6,000 - but many insurance plans will cover the cost of
the pump and the supplies that go along with it, greatly
reducing the out-of-pocket expense of a person or
family. Remember that insulin pumps are usually
considered to be “durable medical equipment” to most
insurance companies. The pump companies have people who
will work with your doctor as well as with your
insurance company to try and get everything approved.
Should you not be approved for a pump the first time
around, don’t give up; many insurance companies know
less about these pumps than you do, so stay informed and
educate them if you must, in order to receive what you
need.
New
Treatment Options
Insulin Pump
Implants - researchers are currently working to develop
an insulin pump which can be permanently implanted to
measure blood sugar levels and deliver the exact amount
of insulin needed. A device such as this would make
it possible to mimic the action of natural insulin
delivery.
Insulin Capsule
Implant - scientists are making progress with an insulin
capsule which can be implanted to continuously produce
insulin and releases it into the bloodstream. It
contains insulin-secreting cells that borrow nutrients
from the body, allowing it to keep producing insulin
indefinitely. One of the challenges in creating such an
implant was to overcome the natural reaction of the
body’s immune system to reject and destroy a foreign
object. Luckily, with the use of microchip technology, a
capsule has been created that will not come under the
attack of the body’s immune system. Before an implant
such as this can be placed on the market, tests must
still be done in order to determine the long-term usage
and ideal dosage level needed to perfect it for general
use, which is still several years away.
Insulin Inhalers
- although daily injections of insulin would still be
needed, inhaled insulin is currently in clinical trials
and may be headed for quick approval from the Food and
Drug Administration (FDA). These inhalers are about the
size of a flashlight and use a rapid-acting insulin
which is sprayed and inhaled into the mouth. Coating the
mouth, throat and tongue, the insulin is able to pass
quickly into the bloodstream.
Insulin Pill -
believe it or not, the discovery of a new polymer
substance may allow for the development of an effective
insulin pill. When the polymer is used to coat a pill,
it allows insulin to get into the bloodstream without
being destroyed by the digestive system. So far, it has
only been tested in animals, and some experts are
questioning whether insulin in a pill form would prove
to be safe or useful, since dosing requirements are is
so critical and vary so often.
Continuous
Monitoring Device - The FDA has approved a
wristwatch-like device that provides more information
for managing diabetes. It is intended to be used along
with, but not as a replacement for, the fingertip blood
test to monitor glucose, in order to ensure accurate
results. Called the GlucoWatch Biographer, it works by
extracting fluid through the skin by sending out tiny
electric currents. The watch can be worn up to 12
consecutive hours, producing 3 monitor readings every
hour, even while you’re asleep. An alarm will sound if
blood glucose levels are detected to be dangerously low,
or if a measurement was skipped. The watch can detect
the presence of both by excessive sweat. The device is
available only by prescription to detect trends and
track patterns in glucose levels in adults age 18 and
older.
Islet Cell
Transplant - this new treatment comes from a technique
known as an islet cell transplant which has shown
promise in people with type 1 diabetes. Islet cells are
found in the pancreas, and the procedure, called the
Edmonton technique, has resulted in seven patients
becoming insulin free for up to 14 months after
treatment. Clinical trials have now begun at 10 national
diabetes centers to see if the insulin reversal can be
successful with more patients. The Edmonton technique
uses islet cells from two or more donor pancreases. The
cells are transplanted into a person with diabetes and
then special medications are given to prevent rejection
of the new islet cells. One difficulty with the
transplant is that even though a person may become free
of the need to take insulin, the medications to prevent
rejection of new tissue must be taken for a lifetime,
and these medications can have side effects.
Gene Therapy -
recent reports show that research into gene therapy for
different aspects of diabetes is beginning to show some
promise. Scientists have identified a gene called SHIP2
that appears to regulate insulin, which would make SHIP2
a potential gene therapy target for the treatment of
type 2 diabetes aimed at improving the individual’s
insulin regulation. There’s also a protein that blocks
the overgrowth of blood vessels in the eyes which
is being studied as a possible form of gene therapy for
diabetic retinopathy, and it may also be used to treat
macular degeneration.
A Possible
Vaccine Against Diabetes? - scientists have developed
the world’s first drug that stops the destruction of
pancreatic beta cells in humans. It offers the
possibility of preventing type 1 diabetes in people at
high risk and of halting its progress in people newly
diagnosed with it. The vaccine contains a drug which is
a peptide (a type of protein). By modifying a small
portion of the protein, a drug has been created which
can selectively block the activity of immune cells which
tend to attack the pancreas. In other words, the drug or
“vaccine” deactivates the cells which attack the
pancreas without interfering with the rest of the body’s
immune system.
