Diagnosis
The nature of the symptoms in conjunction with
abnormalities in the blood and urine tests helps to determine the level of
diagnosis and treatment. For example, if a person has normal kidney function
and the protein levels in the urine are mildly above normal, your doctor will
discuss closely monitoring your kidney function, as well as recommending
lifestyle and dietary changes. If the condition should change, as in worsening
kidney function or higher levels of proteinuria, your doctor will often recommend a kidney biopsy to help determine the type of process occurring.
The
kidney biopsy procedure is usually performed by a nephrologist or
interventional radiologistma type of doctor who does this type of
procedure quite frequently. The kidney biopsy is not surgery and is
commonly done in the radiology department. The sample that is required
is roughly the same size as the white part of your finger.
nail.
The whole procedure takes roughly twenty minutes and will be fully
explained to you. After the sample is obtained, it will be sent to a
pathologist who specializes in kidney disease, who will then examine the
biopsy specimen under a microscope to determine the process of
inflammation. This procedure's risks include bleeding, so you will be
asked to stay in the hospital overnight for observation.
Causes of the Inflammation
What
causes the inflammation in these disorders? What is the trigger that
predisposes the kidney to be the recipient of these high-level
inflammatory syndromes? Why are some people more inclined than others to
get this? Part of the answer to these complex questions may be as
simple as the food choices we make.
We
can all develop allergies to the foods that we eat. In some people,
these food allergies can trigger a significant inflammatory reaction in
the kidneys causing either GN or NS. A prevalent example is an allergy
to gluten, which is a common ingredient in many types of bread,
including wheat and rye. A gluten allergy can cause an inflammatory
process in your stomach and intestines called celiac disease. Having
celiac disease increases your risk of developing any form of nephritis
or nephrotic syndrome. There have been several cases reported of either
NS or GN in people who had celiac disease. The advent of gluten free
foods has been a blessing to those with this syndrome.
In
another study, adults diagnosed with NS who ate a low allergy diet had a
dramatic reduction in proteinuria. Moreover, in a study focusing on
children who had been diagnosed with NS, there was a dramatic reduction
in proteinuria when cow's milk was removed from the diet. And many of the children's urine protein levels
remained low in follow-up. There are other reported cases where just by
changing the nature of their diets, patients with other types of GN
like IgA nephropathy were able to maintain kidney function and reduce
proteinuria.
So
what does this information suggest? It hints that there may be
something in the food we are eating that is triggering nephritis or NS.
But is it the preservatives, the food additives, or the coloring? Is the
way the food is prepared? Or, is it a residual effect of how the farm
animals are raised? Unfortunately, it isn't yet clear but hopefully will
be sometime soon.
The
information in these studies also suggests that one initial method of
treating these conditions should be a low-allergy, inflammatory-free
diet. It also suggests that figuring out what food allergies are present
may be of benefit. Why certain people are more affected than others,
however, remains a mystery.
Standard Treatment Approaches
The
severity of kidney disease and the amount of protein in the urine will
determine the degree of treatment. For those patients with mild disease -
minimal proteinuria and normal or near-normal kidney function - your
kidney doctor will likely monitor you closely. She will be asking you to
obtain blood work on a routine basis to watch your kidney function, as
well as for a urine test to follow your protein levels. In addition, she
will prescribe either an ACE Inhibitor or ARB for its protein-reducing
properties, and will closely follow your blood pressure and cholesterol
levels. If you have significant edema, especially in your legs, your
doctor may start you on a diuretic like furosemide (Lasix) to help with
the swelling.
If
your kidney function is abnormal or you are spilling a significant
amount of protein in your urine, your doctor will likely talk with you
about starting treatment with medications that can affect your immune
system. This includes the use of medication such as prednisone,
cyclosporine (Neoral, Sandimmune, or Gengraf), cyclophosphamide
(Cytoxan), and mycophenolic acid (Cellcept). These medications
are not without side effects. Some of them, including cyclosporine
(Neoral, Sandimmune, or Gengrat) and myoophenolic acid (Cellcept), are
also used for those who have undergone an organ transplant and need them
to suppress their immune systems in order to prevent rejection. You
need to speak with your kidney doctor at length regarding the benefits
and risks of initiating such treatment. If your kidney function has been
severely affected by the inflammatory process (GFR < 10 ml/min), you
may also be asked to start dialysis. To find out more, you can check out Diagnosis Of Chronic Kidney Disease.
