NEPHROTIC
SYNDROME
About Your
Diagnosis
Each kidney is composed of 1
million fine filters to cleanse the blood of poisons. They are designed to keep
the desired components in the bloodstream and to excrete the harmful substances.
Sometimes there is “leakiness” of the filter leading to the loss of
proteins from the blood. The loss of these proteins can result in swelling
(edema), seen initially in the ankles and face. This entity is termed nephritic
syndrome. There are a variety of kidney problems that can lead to nephrotic
syndrome: the most common are primary inflammatory states of the kidney (called
glomerulonephritis), and there are other
diseases
that can damage the kidney as a
consequence. The condition is not transmissible. Nephrotic syndrome is seen
frequently in kidney practice, although it is unusual in a general practice. It
can vary in severity from patient to patient. Typically, most patients see their
physician because of swollen ankles/legs, or even a swollen face observed at
first rising in the morning. The doctor finds protein in the urine on testing.
Subsequent blood tests will confirm the diagnosis of nephritic syndrome. In
order for a cause to be diagnosed, to direct therapy, you may see a nephrologist
for a biopsy. This is where the physician takes a small piece of kidney tissue
with a special needle (no surgery usually needed). All patients with nephrotic
syndrome will have a tendency to high cholesterol levels in the blood. Some
patients have a progressive loss in kidney function after developing this
condition.
Living With Your
Diagnosis
Nephrotic syndrome is a
painless condition under most circumstances. Patients may gain massive amounts
of water weight, to their distress and discomfort. Pain may be a sign of an
underlying new infection, a clot in the leg or pelvis (especially if accompanied
by redness and local tenderness), or inflammation in the abdomen. There will be
a tendency to hold on to the water and salt that you take with your diet; hence
the need for diet modification. You will have a high cholesterol level that
might require medications to help improve it, in addition to the dietary
recommendations your doctor will
suggest.
Treatment
Initially,
the doctor will begin “water pills” (diuretics) to remove excess
water (e.g., furosemide [Lasix]). Occasionally you might need to rest in
hospital so the Lasix can be given by vein to be more effective. It is ideal to
weigh yourself daily to see how successful the diuretic therapy is. There are
additional and alternative diuretics that may be used, depending on the severity
of the nephritic edema and its responsiveness. Depending on your biopsy results,
you might be offered treatment with powerful drugs against inflammation:
prednisone, cyclophosphamide, or chlorambucil, for example. Your doctor will
want you to remain as active as possible because nephrotic syndrome is
associated with an increased tendency to develop clots in the
legs.
There are side effects seen with
these drugs. Lasix can cause a rash, low blood pressure, and low potassium and
magnesium levels (these will be monitored closely by your physician). Prednisone
can lead to hypertension, high blood glucose, stomach irritation, osteoporosis,
and changes in the skin, to name a few (your physician can counsel you on the
remainder of effects).
The
DOs
• Do stay out of bed and
mobile to encourage fluid loss and discourage
clots.
• Do take the diuretic pills
as often as they are prescribed. They may prove less effective because of poor
absorption from the gut, so large doses might be
needed.
• Do take the dietary and
fluid intake to heart: the purpose of the therapy is to reduce the amount of
salt and water in your system.
• Do
avoid foods rich in cholesterol.
• Do
eat plenty of calories to help keep your strength up while the treatment is
underway.
• Do weigh yourself daily
and keep a log to map your progress and halt a
decline.
The
DON’Ts
• Don’t become
sedentary.
• Don’t
smoke.
• Don’t take
over-the-counter pills (especially nonsteroidal drugs like ibuprofen or
Naproxen) that will confound the medical management of nephritic
syndrome.
• Don’t forget the
diet and fluid restrictions to help you get better
faster.
• Don’t forget your
medicines. Call the physician if there is a problem taking
them.
• Don’t forget to weigh
yourself to monitor progress.
When to
Call Your Doctor
Call your physician if
you have shortness of breath, or pain in the chest, abdomen, or legs. Call if
you have fevers or chills. Record your weights and let your doctor know how the
treatment is going. Always tell your doctor if you have problems with the
therapy. A simple, timely explanation may go a long way to reassure you and your
family members.
