Things you
should know about kidney disease and lupus
by Groshan Fabiola
Studies revealed that about a
third of patients that have systemic lupus erythematosus can develop a kidney
disease called lupus nephritis or lupus glomerulonephritis.Lupus nephritis
usually shows very few signs. It doesn't cause pain or burning during urination
and also it does not produce pain in the abdomen or back.The first symptom the
patient with lupus nephritis usually experiences is puffiness in the legs,
ankles or fingers. This happens because the loss of protein in the urine may
lead to fluid retention with weight gain and swelling.
Sometimes the fact that a patient has lupus nephritis is discovered only after
urine studies are made. It is very possible that if there is made another urine
test, the urine abnormalities to disappear. But there are patients in which the
abnormal findings on urine studies persist or can become even worse in time.
This kind of patients require more studies to determine the best treatment to
control the disease, because there appears the risk for loss of kidney function.
It is important to know that patients having lupus can experience some symptoms
that confuse them and think they have lupus nephritis. For example infections of
the urinary tract with burning on urination, or medications used in lupus
treatment may produce signs that can start the confusion.There are some tests
that can be done in order to find out if a patient has lupus nephritis.
Urinalysis is the most used and the most simple test to do. A urine sample is
studied to find out if there is protein and blood cells which are not normally
found in the urine.If in the urine sample there are found red blood cells, white
blood cells, casts(excretion in the urine of protein or blood cells that collect
within the tubules of the kidney), or there is discovered the presence of
protein, there exists the possibility of lupus nephritis, and further tests are
necessary.Sometimes, it is done a urine collection over a period of 24 hours to
measure the kidneys' ability to filter waste products.
Blood studies can also be performed, and we can mention the blood urea nitrogen
and serum creatinine. These are tests that are made to find out if waste
products are being removed properly by the kidney and are not building up in the
blood.By measuring the serum albumin, it can be determined if there is a low
protein level in the blood, and chemistry studies such as the serum sodium,
potassium, and bicarbonate determine the imbalances of salt and water in the
blood.There can be also made blood tests in order to determine if there are
abnormalities of the immune system.
An intravenous sonogram or pyelogram can be made to determine the size and shape
of the kidneys. Usually this test takes place before a kidney biopsy.The kidney
biopsy takes place in order to confirm the diagnosis of lupus nephritis. It is
made by inserting a needle through the skin of the back and removing a tiny
piece of the kidney.Then, the small part taken from the kidney is analyzed under
the microscope in order to determine how much inflammation or permanent damage
is present within the kidney.
There are four most common types of nephritis: focal or diffuse proliferative
nephritis, mesangial nephritis and membranous nephritis.
The treatment for lupus nephritis must be individualized, because there are
different patients having different needs. It is important that all factors that
appear to be taken in consideration when deciding the treatment.General
principles of medical management of kidney disease include anti-hypertensive
drugs to control increased blood pressure, diuretic agents to help eliminate
excess fluid, changes in the diet to control the intake of salt, proteins and
calories. These are very important in lupus nephritis.
Corticosteroids are often used to treat lupus nephritis. We can mention here
prednisolone, prednisone and methylprednisolone. There still are some unanswered
question about how corticosteroids work and how they may be most effectively
used. Usual, high doses of corticosteroids are given until there appears
improvement in the lupus nephritis. Then , the dose is reduced, but there is
done a careful observation by the physician to make sure that the nephritis
doesn't get worse.If corticosteroids are given for long periods, there can
appear side effects, like easy bruising, increase in appetite and fluid
retention with weight gain, cataracts, thinning of the hair, an increase in the
risk of infection, diabetes and other.
When patients do not respond at corticosteroid treatment, they are given
Cytotoxic or immunosuppressive drugs such as azathioprine or cyclophosphamide.
The effect of these drugs is to block the function of the immune system.As a
result, further damage to the kidneys is prevented. However, even if these drugs
may be beneficial, they can also bring serious complications.
Although there is appropriate treatment, there are patients that develop
progressive loss of kidney function and renal failure. This requires the use of
artificial dialysis, and that can be done by hemodialysis or peritoneal
dialysis.Also, it can be made a kidney transplantation, and it is known that
this has been very successful in patients with renal failure from lupus
nephritis.
Over the years, science advanced in the understanding of what causes lupus
nephritis, and there were made improvements in ways to treat patients.
