to a patient. Transplant nursing is becoming even
more exciting, as medical professionals have developed
strategies within the last few decades that have
expanded the living donor pool. |
Terri Cook, RN, has met patients with such advanced
stages of lung disease that they couldn't even sneeze.
But, after these patients-some of whom were in wheelchairs-had
undergone lung transplants, Cook has seen them ride
horses in horse shows, run farms and play basketball.
"It's exciting when it works and people feel they
have such a benefit from transplants, and I guess that's
what keeps me doing [my work as a transplant coordinator],"
said Cook, coordinator and member of the lung transplant
team at Johns Hopkins Hospital in Baltimore.
Transplant nursing is becoming even more exciting,
as medical professionals have developed strategies within
the last few decades that have expanded the living donor
pool. The strategies also have allowed medical professionals
to perform rescue therapy on patients who produced antibodies
after their transplants to attack the donated kidney.
Gone are the days when kidney donors and recipients
had to be related and have compatible blood types with
a negative crossmatch-meaning that the recipient could
not have preformed antibodies against the donor's blood.
Today, medical professionals use plasmapheresis, which
removes antibodies, on kidney recipients whose blood
types are incompatible with their donors' or who have
positive crossmatches with their donors.
Then, kidney recipients undergo a procedure called
intravenous immunoglobulin (IVIG) to restore the antibodies
that would protect them from infection but not attack
the donated kidney. IVIG modulates the immune system
so that it either no longer makes the antibodies or
no longer responds to the donor's antigens, said Mary
Jo Holechek, MS, CRNP, CNN, nurse practitioner in the
adult abdominal organ transplant service at Hopkins.
The living donor pool also has increased because of
the advent of living liver donor transplants and the
laproscopic procedure for kidney donors.
Although only a handful of facilities in the United
States perform plasmapheresis, IVIG, living liver donor
transplants and laproscopic procedures, Holechek said
she sees more facilities using the procedures within
the next five to 10 years. As more facilities adopt
the procedures, more patients should receive transplants
and live longer, better-quality lives.
Medical professionals have used plasmapheresis, or
the procedure of removing a patient's plasma, where
antibodies reside, to treat various diseases since the
1970s. Hopkins began using the procedure on kidney patients
in 1994.
During the first plasmapheresis on a kidney patient
at Hopkins, the donor and recipient had a negative crossmatch
before the transplant; however, the procedure was used
on the recipient after the transplant because the recipient
had begun to produce large quantities of antibodies
to attack the donated kidney.
From this form of "rescue therapy," where
antibodies are removed after the kidney transplant,
pre-emptive therapy-or removing the antibodies before
the transplant-evolved, so that plasmapheresis could
be used even on recipients who showed a positive crossmatch
before the transplant. Hopkins first used the pre-emptive
procedure in 1998.
