Young, insulin-dependent sufferers of Diabetes mellitus
can be afflicted with a number of conditions, caused by a malfunctioning
metabolism, such as rhenal failure, blindness, extensive damage to nervous
system and arteries with severe consequences for the blood supply to
the heart, brain or extremities. This disease is caused by the destruction
of insulin-producing islet cells in the pancreas. Glucose metabolised
through the intake of food cannot enter body cells in the absence of
insulin. This will cause multiple cell function failure.
As a treatment for Diabetes
mellitus Type I, insulin must therefore be injected at regular intervals
to ensure near-normal blood glucose levels. If levels cannot be maintained,
damage as described above and additional conditions will be the outcome.
Long-term damage is likely to occur.
This vicious cycle can be arrested
and reversed by a combined pancreas and kidney transplant, which will
eliminate both rhenal failure and establish a normal glucose metabolism.
A pancreas transplant only (without kidney) can be beneficial in exceptional
circumstances.
Side effects:
As with all other organ transplants, patients
will have to take medication on a life-long basis, to suppress the rejective
reaction of the immune system. These drugs are essential to keep transplanted
organs functioning and have to be taken at precise time intervals. The
required dosage must be determined by assessing levels in the blood
of the patient. One of the side effects of the procedure is an increased
vulnerability to bacterial, viral and fungal infections. Severe diseases
such as lymphoma may also be induced by a long-term intake of immune
system suppressing drugs.
Increased survival
chances:
Despite these side effects, the longer-term success
of a pancreas-kidney transplant is excellent, with more than 80% of
the organs still operational after 5 years. For young diabetics this
is good news: their survival chances are better and life quality improves
markedly as daily injections and frequent dialyses are no longer necessary.
There is no need to transplant patients who do not
suffer from diabetes-induced conditions and can keep their blood sugar
at normal levels.
